Abstract

Method and apparatus for use by mobile communication devices for communicating short messages of the emergency type via wireless communication networks. A user input request for communicating a short message is received through a user interface of the mobile device. If the user input request is for an emergency message, a second message center address is read from the memory and provided in a message center address field of the short message. The network identifies the second message center address in the message center address field and, in response, causes the short message to be sent to the emergency message center which is local to the network. This way, when the mobile device is visiting a non-home wireless network, the short message is routed to the appropriate local emergency message center.

Description

METHODS AND APPLIANCES FOR USE IN THE COMMUNICATION OF EMERGENCY-TYPE SHORT MESSAGES FROM DEVICE DEVICES MOBILE COMMUNICATION DESCRIPTION OF THE INVENTION The present disclosure relates generally to the communication of short messages from a mobile communication device 'via a wireless communication network, and more particularly to the communication of short messages (ie, Short Message Service). or SMS messages) of the emergency type when the mobile communication device is operating in a wireless (non-local) network visiting outside of its local wireless network. In current communication systems, a user of a mobile communication device can often communicate by sending a Short Message through the Short Message Service ("SMS"). When the user sends a SMS message, it is usually routed to the SMS Service Center ("SMS-SC") of the user's local network. For example, if the user's local network was in New York, NY, their SMS messages would be routed to their local network SMS-SC in New York, NY even though it sends a SMS message while it is touring London, England, and is outside of your local network For most applications, routing SMS messages to the user's local network SMS-SC does not present any problems, but there are certain situations, such as a SMS message requesting emergency assistance, where it would be preferable for the SMS message to be sent to an SMS-SC in the currently visited network and its content sent to an entity that provides local emergency assistance. Currently, to provide local emergency assistance to the user, it would be necessary for a Short Message Entity ("SME") receiving in the user's local network to provide the details of the emergency SMS message to a local SME in a visited network. currently where the user requires emergency assistance. Such mechanisms can be quite complex and expensive, and may well introduce delays and ineffective assistance. Methods and apparatuses for being used by mobile communication devices for communicating short messages of emergency type by means of wireless communication networks are described herein. In an illustrative example, a first address of the message center associated with a local message center and a second address of the message center associated with an emergency message center are stored in the memory of the mobile device. The memory can be a removable memory module, such as a Subscriber Identity Module (SIM), for the mobile device. A request for user input to communicate a short message is received through a user interface of the mobile device. If the user's entry request is identified as being an emergency message, the second address of the message center is read from the memory and is provided in an address field of the message center of the short message. The short message having the second address of the message center in the address field of the message center is then transmitted by the mobile device to the wireless network. The network identifies the second address of the message center in the address field of the message center and, in response, causes the short message to be sent to the emergency message center which is local to the network. In this way, when the mobile device visits a non-local wireless network, the short message can be routed to the appropriate local emergency message center. The mobile device can receive the second address of the message center in a transmission channel of the wireless network and store it by associating it with a wireless network identification of the wireless network. In an alternative technique, an indicator (e.g., a Transport Protocol ID) of the short message is set to indicate that the short message is an emergency message instead of providing the second destination message in the address field of the center of messages. BRIEF DESCRIPTION OF THE DRAWINGS FIGURE 1 is a block diagram of a system of communication which includes a mobile communication device for communicating by means of a wireless communication network; FIGURE 2 is a more detailed example of a mobile device used in the wireless network of FIGURE 1; FIGURE 3 is a simplified exemplary wireless network environment in which the techniques of the present disclosure can be practiced; FIGURE 4 is an exemplary flow chart illustrating a routing process of a short emergency type message originated by the mobile device to a local short message service center; FIGURE 5 is an exemplary block diagram of the wireless communication network configured to route the short message to a local destination in accordance with FIGURE 4; FIGURE 6 is an exemplary flow chart illustrating a routing process of an emergency short message originated by the mobile device to a local short message service center; FIGURE 7 is an exemplary block diagram of the relevant components of the mobile device configured to route the short message to a local destination in accordance with FIGURE 6; FIGURE 8 is an illustrative example of a visual screen of the mobile device which displays indications to be used when sending short emergency messages of the mobile device; FIGURE 9 is a process flow diagram for describing a method to be used in communicating short emergency messages originating from the mobile device; and FIGURE 10 is a process flow diagram for describing a method to be used when transmitting emergency address information via the wireless network. Methods and apparatuses for being used by mobile communication devices for communicating short emergency messages via wireless communication networks are described herein. In an illustrative example, a first address of the message center associated with a local message center and a second address of the message center associated with an emergency message center are stored in the memory of the mobile device. The memory can be a removable memory module, such as the Subscriber Identity Module (SIM), for the mobile device. A user's input request is received to communicate a short message through a user interface of the mobile device. If the user's entry request is identified as an emergency message, the second The message center address is read from the memory and is provided in an address field of the message center of the short message. The short message having the second address of the message center in the address field of the message center is then transmitted by the mobile device to the wireless network. The network identifies the second address of the message center in the address field of the message center and, in response, causes the short message to be sent to the emergency message center which is local to the network. In this way, when the mobile device visits a non-local wireless network, the short message can be routed to the appropriate local emergency message center. The mobile device can receive the second address of the message center in a transmission channel of the wireless network and store it by associating it with a wireless network identification of the wireless network. In an alternative technique, an indicator (e.g., a Transport Protocol ID) of the short message is set to indicate that the short message is an emergency message instead of providing the second destination message in the address field of the center of messages. To illustrate the basic architecture of the network, FIGURE 1 shows a block diagram of a communication system 100 which includes a mobile communication device 102 which communicates through a network 104 wireless communication. In the preferred embodiment, the mobile communication device 102 is a mobile station and therefore this term is used substantially throughout the specification. The mobile station 102 preferably includes a visual screen 112, a keyboard 114, and perhaps one or more user interface (Ul) 116 auxiliaries, each of which is coupled to a controller 106. The controller 106 also couples to a circuit system 108 of radio frequency (RF) transceiver and antenna 110. In most modern communication devices, the controller 106 is integrated as a central processing unit (CPU) which operates the operating system software in a memory component (not shown). The controller 106 will normally control the complete operation of the mobile station 102, while the signal processing operations associated with the communication functions are typically performed in the RF transceiver circuit system 108. The controller 106 contacts the screen 112 of the device to display the received information, stored information, user inputs and the like. The keyboard 114, which may be a telephone-type numeric keypad or full alphanumeric keyboard (preferably a full QWERTY type keyboard), is normally provided for inputting data for storage in the mobile station 102, information for transmission to the network 104, a telephone number for placing a telephone call, commands to be executed in the mobile station 102, and possibly other inputs different from the user. As a hand-held portable / mobile electronic device, the mobile station 102 includes a battery interface 134 for receiving and carrying one or more rechargeable batteries 132. The battery 132 provides electrical power (most if not all) to the electrical circuit system in the mobile station 102, and the battery interface 134 provides an electrical and mechanical connection for the battery 132. The battery interface 134 is coupled to a regulator 136 which provides a regulated V voltage for all electrical components of the device. The mobile station 102 sends communication signals to and receives communication signals from the network 104 on a wireless link via the antenna 110. The RF transceiver circuit system 108 and antenna 110 perform functions similar to those of the base station 120 and the tower 118 of the antenna, including for example modulation / demodulation and possibly encoding / decoding and encryption / decryption. It will be apparent to those skilled in the art that that RF transceiver circuit system 108 will be adapted to the particular wireless network or networks in which the mobile station 102 intends to operate.

The mobile station 102 operates using a Subscriber Identity Module (SIM) 140 which is connected to or inserted into the mobile station 102 at an interface 142 of the SIM. The SIM 140 is a type of a conventional "smart card" used to identify an end user (or subscriber) of the mobile station 102 and to customize the device, among other things. Without the SIM 140, the wireless terminal is not fully operational for communication through the wireless network 104. By inserting the SIM 140 into the wireless terminal, an end user can have access to any and all of its subscribed services. In order to identify the subscriber, the SIM 140 contains some user parameters such as an International Mobile Subscriber Identity (IMSI). In addition, the SIM 140 is typically protected by a four-digit Personal Identification Number (PIN) which is stored therein and only the end user knows it. An advantage of using the SIM 140 is that the end users are not necessarily bound to any simple physical wireless device. Typically, the only element that personalizes a wireless terminal is a SIM card. Therefore, the user can access the subscribed services using any wireless terminal equipped to operate with the user's SIM. The mobile station 102 may consist of a single unit, such as a data communication device, a cell phone, a multi-function communication device with voice and data communication capabilities, a personal digital assistant (PDA) that enables wireless communication, or a computer that incorporates a internal modem. Alternatively, the mobile station 102 may be a multi-module unit comprising a plurality of separate components, including but not limited to a computer or other device connected to a wireless modem. In particular, for example, in the block diagram of the mobile station of FIGURE 1, the circuit system 108 of RF transceiver and antenna 110 can be implemented as a radio modem unit that can be inserted into a port on a computer laptop In this case, the laptop computer could include the screen 112, the keyboard 114, and one or more auxiliary UIs 116, and the controller 106 incorporated as the computer's CPU. It is also contemplated that a computer or other equipment normally not capable of wireless communication may be adapted to connect to and effectively assume control of the RF transceiver circuit 108 system and antenna 110 of a single unit device such as one of those described. previously. In FIGURE 1, the mobile station 102 communicates through the wireless communication network 104. In the FIGURE 1, the wireless network 104 is a network which operates in accordance with the Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS) technologies. The wireless network 104 includes a base station 120 with a tower 118 of the associated antenna, a Mobile Switching Center (MSC) 122, a Local Location Register (HLR) 150, a General Service Support Node of General Radio Service per Packet (GPRS) (SGSN) 126, and one GPRS Gateway Support Node (GGSN) 128. The MSC 122 is coupled to the base station 120 and to a telephone network, such as a fixed line network 124 (e.g. , Public Switched Telephone Network or PSTN). The SGSN 126 is coupled to the base station 120 and the GGSN 128, which in turn is coupled to a private or public data network 130 (such as the Internet). The HLR 150 is coupled to the MSC 122, SGSN 126, and GGSN 128. The base station 120, including the associated sub-controller and antenna tower 118, provides wireless network coverage for a particular coverage area commonly referred to as a "cell". " The base station 120 transmits communication signals to and receives communication signals from the mobile stations within its cell via the tower 118 of the antenna. The base station 120 normally performs such functions as modulation and possibly coding and / or encryption of signals that are going to transmitting to the mobile station in accordance with particular communication protocols and parameters, usually predetermined, under the control of its controller. The base station 120 similarly demodulates and possibly decodes and deciphers, if necessary, any communication signals received from the mobile station 102 within its cell. Communication parameters and protocols may vary between different networks. For example, a network may employ a different modulation scheme and operate at different frequencies than other networks. The wireless link shown in the communication system 100 of FIGURE 1 represents one or more different channels, typically different radiofrequency (RF) channels, and associated protocols used between the wireless network 104 and the mobile station 102. An RF channel is a limited source that must be retained, typically due to full bandwidth limits and limited battery power of the mobile station 102. Those skilled in the art will appreciate that a real-time wireless network may include hundreds of cells, each served by a different base station and transceiver, depending on the desired complete expansion of the network coverage. All controllers of the base station and base stations can be connected by multiple switches and routers (not shown), controlled by multiple controllers net. For all mobile stations 102 registered with a network operator, permanent data (such as the user profile of the mobile station 102) as well as temporary data (such as the current location of the mobile station 102) are stored in the HLR 150 In case of a voice call to the mobile station 102, the HLR 150 is searched to determine the current location of the mobile station 102. A Visitor Location Register (VLR) of the MSC 122 is responsible for a group of location areas and stores the data of those mobile stations that are currently in their area of responsibility. This includes portions of the permanent mobile station data that has been transmitted from the HLR 150 to the VLR for faster access. However, the VLR of the MSC 122 can also allocate and store local data, such as temporary identifications. Optionally, the VLR of the MSC 122 can be improved for more efficient coordination of GPRS services and functionality and without GPRS (eg, search for people, voice calls to the circuit which can be done more efficiently by SGSN 126, and location updates). of GPRS and without GPRS combined). The MSC 122 is also coupled to a Short Message Service Service Center (SMS-SC) 154 which is a message center for the communication of Short Message Service (SMS) messages. The SMS makes use of the SMS-SC 154 which acts as a storage system and transmits to retransmit short messages. Messages are stored in the network until the destination device becomes available, so an end user can receive or transmit an SMS message at any time, whether a voice call is in progress or not. Being part of the GPRS network, the GPRS Service Support Node (SGSN) 126 is at the same hierarchical level as the MSC 122 and continues tracking individual mobile station locations. The SGSN 126 also performs security and access control functions. The GPRS Gateway Support Node (GGSN) 128 provides intercommunication of networks with switched networks to external packets and connects with the SGSNs (such as the SGSN 126) via an IP-based GPRS core network. The SGSN 126 performs authentication procedures and configuration of figures based on the same algorithms, keys, and criteria as in an existing GSM. In a conventional operation, the cell selection can be performed autonomously by the mobile station 102 or by the base station 120 which instructs the mobile station 102 to select a particular cell. The mobile station 102 informs the wireless network 104 when it selects again another cell or group of cells, known as a routing area. In order to access the GPRS services, the mobile station 102 first makes its presence known to the wireless network 104 by performing what is known as a "connection" of the GPRS. This operation establishes a logical link between the mobile station 102 and the SGSN 126 and makes the mobile station 102 available to receive, for example, calls by means of the SGSN, notification of incoming GPRS data, or SMS messages in the GPRS. In order to send and receive data from the GPRS, the mobile station 102 helps activate the data address of the packet that it wants to use. This operation makes known mobile station 102 for GGSN 128; the intercommunication of networks with external data networks can start from then on. The user data can be transmitted transparently between the mobile station 102 and the external data networks using, for example, encapsulation and tunneling. The data packets are equipped with GPRS-specific protocol information and are transmitted between the mobile station 102 and the GGSN 128. As apparent from the above, the wireless network includes fixed network components including RF transceivers, amplifiers, controllers of the base station, network servers, and servers connected to network. Those skilled in the art will appreciate that a wireless network can be connected to other systems, possibly including other networks, not shown explicitly in FIGURE 1. A network will normally be transmitted at least to some type of paging and system information continuously, even if not packet data is actually exchanged. Although the network consists of many parts, all of these parts work together to result in certain behaviors in the wireless link. FIGURE 2 is a detailed block diagram of a preferred mobile station 202 which can be used in system 100 of FIGURE 1. Mobile station 202 is a two-way communication device having at least data communication capabilities and voice, including the ability to communicate with other computer systems. Depending on the functionality provided by the mobile station 202, it can be called a data messaging device, a two-way person search, a cell phone with data messaging capabilities, a wireless Internet device, or a data communication device. (with or without telephone capabilities). The mobile station 202 includes a battery interface 254 for receiving one or more rechargeable batteries 256. Such a battery 256 provides electrical power to most if not the entire electrical circuit system in the mobile station 202, and the battery interface 254 provides an electrical and mechanical connection for it. The battery interface 254 is coupled to a regulator (not shown in FIGURE 2) which regulates power to the entire circuit system. The mobile station 202 will normally incorporate a communication subsystem 211, which includes a receiver 212, a transmitter 214, and associated components, such as one or more antenna elements 216 and 218 (preferably integrated or internal), local oscillators 213 ( LOs), and a processing module such as a digital signal processor (DSP) 220. The communication subsystem 211 is analogous to the RF transceiver circuit system 108 and the antenna 110 shown in FIGURE 1. As will be apparent to those experts in the field of communications, the particular design of the communication subsystem 211 depends on the communication network in which the mobile station 202 intends to operate. The requirements for accessing the network will also vary depending on the type of network used. In GPRS networks, for example, access to the network is associated with a subscriber or user of mobile station 202. A GPRS device therefore requires a Subscriber Identity Module, commonly called a SIM card (ie, SIM 262 of FIGURE 2), in order to operate in the GPRS network. Without the SIM 262 inserted in a SIM interface 264, the station 202 mobile would not be fully functional. The functions of local communication or without network (if any) may be operable, but the mobile station 202 will not be able to perform any of the functions involving communications in the network. SIM 262 includes those features described in relation to FIGURE 1 (ie, those described for SIM 140 of FIGURE 1). The mobile station 202 can send and receive communication signals in the network after the registration of the network is required or the activation procedures have been completed. The signals received by the antenna 216 through the network are input to the receiver 212, which can perform such common receiver functions as signal amplification, frequency downconversion, filtering, channel selection, and the like, and in the example shown in FIGURE 2, analog to digital (A / D) conversion. The A / D conversion of a received signal allows more complex communication functions such as demodulation and decoding to be performed in the DSP 220. Similarly, the signals to be transmitted are processed, including modulation and coding, by example, by the DSP 220. These processed DSP signals are input to the transmitter 214 for digital to analog (D / A) conversion, frequency increase conversion, filtering, amplification and transmission in the network. communication via antenna 218. The DSP 220 not only processes communication signals, but also provides transmitter and receiver control. For example, the gains applied to the communication signals at the receiver 212 and the transmitter 214 can be controlled adaptively through automatic gain control algorithms implemented in the DSP 220. The mobile station 202 includes a microprocessor 238 (which is a implementation of the controller 106 of FIGURE 1) which controls the complete operation of the mobile station 202. The communication functions, including at least data and voice communications, are performed through the communication subsystem 211. The microprocessor 238 also interacts with sub-systems of the additional device such as a screen 222, a flash memory 224, a random access memory (RAM) 226, auxiliary input / output (I / O) subsystems 228, a serial 230 port, a keyboard 232, a speaker 234, a microphone 236, a short-range communications subsystem 240 and any other device subsystem generally designated at 242. The control and data lines extend between a SIM interface 264 and the microprocessor 238 to communicate data between them and for control. Some of the subsystems shown in FIGURE 2 perform functions related to communication while other subsystems can provide device functions or "residents". Notably, some subsystems such as keyboard 232 and screen 222, for example, can be used for both communication-related functions, such as entering a text message for transmission in a communication network, and resident device functions. such as a calculator or to-do list. The operating system software used by the microprocessor 238 is preferably stored in a persistent store such as a flash memory 224, which may alternatively be a read-only memory (ROM) or similar storage element (not shown). Those skilled in the art will appreciate that the operating system, specific device applications, or parts thereof, can be temporarily loaded into a volatile store such as RAM 226. The microprocessor 238, in addition to its operating system functions, preferably allows the execution of software applications in the mobile station 202. A predetermined configuration of applications which controls the basic operations of the device, including at least voice and data communication applications, will normally be installed in the mobile station 202 during its manufacture. A preferred apparatus that can be charged to the mobile station 202 can be a personal data manager (PIM) apparatus that has the ability to organize and manage user-related data elements such as, but not limited to, e-mail, calendar events, voice mails, appointments, and task elements. Naturally one or more memory stores are available in the mobile station 202 and the SIM 256 to facilitate the storage of PIM data elements and other information. The PIM application preferably has the ability to send and receive data elements through the wireless network. In a preferred embodiment, the PIM data elements are integrated, synchronized and seamlessly updated by the wireless network, with the corresponding information elements of the user of the mobile station stored and / or associated with a central computer system thereof. In this way a central replica computer is created in the mobile station 202 with respect to such elements. This is especially advantageous where the central computer system is the user's office computer system of the mobile station. Additional applications may also be loaded to the mobile station 202 through the network, an auxiliary I / O subsystem 228, serial port 230, short-range communications subsystem 240, or any other suitable subsystem 242, and installed by a user in RAM 226 or preferably a non-volatile store (not shown) for execution by the microprocessor 238. Such flexibility in the installation of the application increases the functionality of the mobile station 202 and can provide device functions, improved communication-related functions, or both. For example, secure communication applications may allow electronic commerce functions and other financial transactions to be performed using the mobile station 202. In a data communication mode, a received signal such as a text message or web page download will be processed by the communication and input subsystem 211 for the microprocessor 238. The microprocessor 238 will preferably also process the signal for input to the screen 222 or alternatively to the auxiliary I / O device 228. A user of mobile station 202 can also write data elements, such as e-mail messages or short message service (SMS) messages, for example, use keyboard 232 together with screen 222 and possibly device 228 of I / Or auxiliary. The keyboard 232 is preferably a complete alphanumeric keyboard and / or a telephone-type keypad. These written elements can be transmitted in a communication network through the communication subsystem 211. The handling and delivery of information from the email message will be described later in connection with Figures 4-6.

For voice communications, the complete operation of the mobile station 202 is substantially similar, except that the received signals would be output to the horn 234 and the signals for transmission would be generated by the microphone 236. The audio I / O subsystems or alternative voice, such as a voice message recording subsystem may also be implemented in the mobile station 202. Although the preferred audio or voice signal output is primarily achieved through the speaker 234, the display 222 may also be used to provide an indication of the identity of a calling party, the duration of a voice call, or other information related to the voice call, as some examples. Serial port 230 in FIGURE 2 is typically implemented in a personal digital assistant (PDA) communication device for which synchronization with an end-user desktop computer is a desirable, albeit optional, component. The serial port 230 allows an end user to configure the preferences through an external device or software application and extends the capabilities of the mobile station 202 by providing information or software downloads to the mobile station 202 instead of through a wireless communication network. The alternate download path, for example, may be used to load an encryption key to station 202 mobile through a direct connection and therefore reliable and secure to thereby provide secure device communication. The short-range communications subsystem 240 of FIGURE 2 is an additional optional component which provides communication between the mobile station 202 and different systems or devices, which need not necessarily be similar devices. For example, subsystem 240 may include an infrared device and associated components and circuits, or a Bluetooth ™ communication module to provide communication with similarly permitted devices and systems. Bluetooth ™ is a registered trademark of Bluetooth SIG, Inc. FIGURE 3 is an exemplary environment of the relevant components of the wireless communication system 100 of FIGURE 1 in which the present techniques can be practiced in at least one of the modes prefer them. In this example, the mobile device 102 is displayed when visiting and registering in a non-local wireless communication network 304 ("local network") which has a local SMS-SC 306. Typically, an SMS message transmitted by the mobile device 102 will reach its local SMS-SC 154 associated with its local wireless network 110 through the local wireless network 304 and a communication network 302 such as a traditional fixed line communication network or a wide area network. However, for a certain type of SMS messages, such as an SMS message requesting emergency assistance, the SMS message transmitted from the mobile device 102 is routed to the local SMS-SC 306 on the local wireless network 304, and the The content of the SMS message is sent to an entity that provides local emergency assistance. FIGURE 4 is an exemplary flow chart 400 illustrating a routing process of a short message originated by a mobile visitor device (e.g., mobile device 102 in FIGURE 3) to a local short message service center (FIG. for example, SMS-SC 306 in FIGURE 3) by a local wireless network (e.g., wireless network 304 in FIGURE 3) according to at least one of the preferred embodiments. In block 402 of FIGURE 4, the local wireless network receives a message from the SMS that has a message destination from the mobile device. Typically, the message destination is the address of the intended recipient which is manually inserted or selected by the user of the mobile device, known as the Transport Protocol Destination Address ("TP-DA"). In the case of a short emergency type message, the TP-DA will be a short telephone code such as "911", "112", "999", or any predefined code known to indicate that the short message concerns an emergency situation. . He mobile device also automatically inserts the routing information (ie the local SMS-SC address) to the message for delivery. In response to receiving the message from the mobile device, the local wireless network evaluates the TP-DA and routes the short message to an appropriate SMS-SC. It should be noted that the local wireless network has a stored list of predefined short message destinations, which are used to route the SMS message from the mobile device to an appropriate local destination. The predefined short message destinations can be or include a plurality of emergency center destinations such as, but not limited to, the police, the fire department, the hospital, "911", "112", "999", or any other destinations associated with emergency centers. In block 404 of FIGURE 4, the local network compares the destination of the message (ie, the TP-DA) with the stored list of predefined short message destinations. If a match is found in block 404, the local wireless network routes the SMS message from the mobile device to a local destination corresponding to the predefined destination of the matching short message in the list of predefined short message destinations in block 406 of FIGURE 4. The local destination can be a local SMS-SC or a locally located emergency center. Each destination of the center Emergency may have a corresponding short message destination for a locally located emergency center. The local wireless network can route the SMS message to a local destination in several ways, including replacing the destination of the original message with the local destination and transmitting the short message to the local destination; transmit the short message to the local destination; and generating a new short message having the local destination, attaching the original short message to the new short message, and transmitting the new short message having the short message appended to the local destination. FIGURE 5 is an exemplary block diagram 500 of the network components of the local wireless network configured to route the emergency short message to the local destination according to FIGURE 4. The local wireless network 104 has a message receiver 550 shorts configured to receive a short message having a message destination from a locally registered mobile device such as the mobile device 102 of Figures 1-3. The local wireless network 104 has a memory device 504, which is configured to store the previously described list of predefined short message destinations. A message destination evaluator 506 is coupled to both the short message receiver 550 and the memory 504, and is configured to match the message destination with a predefined destination of short messages from the list of predefined short message destinations in memory 504. A message destination re-director 508 is coupled to the message destination evaluator 506, and is configured to redirect the short message to a local destination corresponding to the predefined short message destination that matches the list of predefined short message destinations. The message destination redirector 508 may also be configured to replace the message destination with the local destination. A short message transmitter 510 is coupled to a message destination re-director 508 and is configured to transmit the short message to the local destination (such as the local SMS-SC 306 of Figure 3). The short message transmitter 510 can also be configured to transmit the short message to the local destination. The local wireless network 304 may also have a message generator 512 coupled to the message destination re-director 508 and the short message transmitter 510, and be configured to generate a new short message having the local destination and to append the short message to the new short message. Alternatively, the mobile device can itself direct the SMS message to an appropriate local destination, such as the local SMS-SC. To illustrate, Figure 6 is an exemplary flow chart 600 illustrating a routing process of the SMS message originated by the mobile device to the local SMS-SC by the mobile device according to at least one of the preferred embodiments. The mobile device may use one or more of its processors (e.g., the microprocessor) to perform the steps of the method, or more particularly, the functional components described below in connection with Figure 7. In block 602 of Figure 6 , the mobile device receives a list of predefined destinations of short messages, which was previously described. The mobile device can receive the list of predefined short message destinations when registering in a non-local network of the mobile device, such as the local network 304. In block 604 of Figure 6, the mobile device generates a message from the SMS that has a message destination. Typically, as described above, the message destination is the address of the intended recipient which is manually inserted or selected by the user of the mobile device, known as the Transport Protocol Destination Address ("TP-DA"). In the case of a short emergency type message, the TP-DA will be a short telephone code such as "911", "112", "999", or any predefined code known to indicate that the short message concerns an emergency situation. . The mobile device also automatically inserts the routing information (ie, the address of the local SMS-SC) to the message for delivery as well. The mobile device compares the message destination with the list of predefined short message destinations in block 606 of FIGURE 6. If the message destination matches a predefined short message destination in the list of predefined short message destinations, the The mobile device transmits the SMS message to a local destination corresponding to the predefined short message destination that matches the list of predefined short message destinations in block 608 of Figure 6. For example, the mobile device can transmit the SMS message to the local destination when replacing the original message destination with the local destination corresponding to the predefined short message destination that matches the local local predefined destination list. Figure 7 is an exemplary block diagram 700 of the mobile device 102 which is configured to route a short message to the local SMS-SC according to Figure 6. The mobile device 102 can integrate the functional components of Figure 7 into one or more of its processors (for example, the microprocessor). As shown, the mobile device 102 has a receiver 702 which is configured to receive the list of predefined short message destinations previously described from the local wireless network 304. The mobile device 102 also has a memory device 704 coupled to receiver 702 which is configured to store the list of predefined short message destinations. The receiver 702 can be configured to receive the list of predefined short message destinations only after the mobile device 102 registers in a non-local network, such as the local wireless network 304. The mobile device 102 also has a short message generator 706, which is configured to generate a short message having a message destination. A destination comparator 708 is coupled to the memory device 704 and the short message generator 706, and is configured to match the message destination with a predefined short message destination from the list of predefined short message destinations stored in the device 704. of memory. A transmitter 710 is coupled to the destination comparator 709, and configured to transmit the short message to a local destination corresponding to the predefined short message destination that matches the list of predefined short message destinations. The destination comparator 708 can further be configured to replace the message destination with the local destination corresponding to the predefined short message destination that matches the local predefined destination local list. Figure 8 is an illustrative example of the visual screen 222 of the mobile device for displaying Information and indications to be used when initiating short messages from the mobile device. The methods of the user interface to be described can be employed in any technique described herein to originate short messages from the mobile device. In general, the processor of the mobile device may be operative to cause the information and indications of Figure 8 to be displayed on the visual screen 222 in response to a user's input request to send a short message. The processor receives alphanumeric text information for the short message in an alphanumeric text input field 852, which the user can manually enter via the user interface via the keyboard 232 or the like. In Figure 8, the alphanumeric text information in the alphanumeric text entry field 852 indicates that the short message is of the emergency type, saying "Help! Please send help to 416 W Bartol, Chicago". The processor also receives information from the destination address (for a number or telephone code) in a destination field 850 for the short message, which the user can manually enter via the keyboard 232 or the like as well. In Figure 8, the destination address information indicates that the short message is an emergency type, since it is a short telephone code for "911". The processor may cause one or more than one plurality of visual indications 830 are displayed on the visual screen 222. Any of the visual indications 830 can be selected or operated by the user of the mobile device using any suitable input device of the mobile device, such as the keyboard 232 (for example, arrow keys up / down and left / right), wheel displacement, tracking ball, as examples, which can use an 812 cursor or placeholder. In Figure 8, the visual indications 830 include an indication 854 for sending messages to be used when sending short messages in a standard, general manner. The visual indications 830 may also include an 802 indication of emergency messages to be used when sending emergency short messages for general emergency services. Other visual indications 830 which can be displayed are more specific and include, as examples, an indication 804 of emergency messages for police services, an indication 806 of emergency messages for fire services, and an indication 808 of emergency messages for ambulance / hospital services. Although the visual indications 830 are shown in Figure 8 as user-actuable objects such as graphical user interface (GUI), the visual indications 830 can alternatively be displayed as functions in a list of menu functions. More generally, any suitable emergency function can be provided in the user interface to be used when sending emergency messages. When the alphanumeric text information has been entered in the alphanumeric text input field 852, and one of the visual indications 830 has been triggered or selected by the user, the processor causes the short message to be processed and sent to the appropriate destination. In one variation, none or all the indications 802, 804, 806, and 808 visuals for emergency services may be displayed before and / or instead of displaying any field 850 of the destination address and / or alphanumeric text entry field 852. In this case, the user navigates through the options presented on the visual screen 222 until the visual indications 802, 804, 806, and 808 are displayed for emergency services. Depending on the situation, the user activates or selects one of the visual indications 802, 804, 806, or 808 corresponding to the emergency situation through the user interface. A detection of driving one of these visual indications 802, 804, 806, or 808 causes the processor to identify or select the appropriate routing / destination information corresponding to the visual indications 802, 804, 806, or 808 from its memory, insert such information into the delivery message (for example, see the discussion below), and display the alphanumeric text entry field 852 for the user to manually enter the alphanumeric text information through the user interface. The field 850 of the destination address and the selected destination address may or may not be displayed on the visual screen 222. In another variation, the alphanumeric text information may be predefined alphanumeric text information which is pre-populated by the processor of the mobile device without any textbook entry required by the user. Therefore, with the use of the visual indications 802, 804, 806 and 808, the user does not need to try to enter any destination address but only selects an appropriate visual indication 802, 804, 806, and 808 corresponding to the situation of emergency. This should be especially important in cases where the user is unfamiliar with the location of the visit where such destination addresses may be unknown or different from those of the local location. Figure 9 is a process flow diagram for describing a method to be used in the communication of emergency short messages originating from the mobile device. The techniques described in relation to Figure 9 can be performed by the mobile communication device using one or more of its processors (for example, the microprocessor). Complementary techniques may be performed by one or more entities or network components in the wireless network, such as the Mobile Switching Center (MSC), or the General Service Packet Radio Service (GPRS) Support Node (SGSN) ). To communicate short messages in relation to the process of Figure 9, the memory of the mobile device 102 stores a first address of the message center associated with a local message center and a second address of the message center associated with a message center. emergency. Preferably, the memory used to store the first and second addresses of the message center is a removable memory module, such as a SIM. As an example, the second address of the message center can be stored in the removable memory module (for example, the SIM) as provided in Table 1 below (see the fields shifted Y + 19 to Y + 30): Table 1. Address Field for the Emergency Service Center Address As another example, the second address of the message center can be stored in a new field of the removable memory module as provided in Table 2 below (see bytes 1 -12): Table 2. Address Field for the Address of the Emergency Service Center The second address of the message center can be called a "global title" address that has a valid format according to E.164 or another type of suitable format (for example, E.212 or E.214). The second address of the message center can be an address that is directly associated with the emergency message center or, alternatively, an address that is indirectly associated with the message center where multiple communication breaks are made in the network until The appropriate emergency message center is reached. Alternatively, the second address of the message center may not be a valid address but only serve as an indication for the network to perform the routing of the emergency message for the short message, where the appropriate message center address for the message center emergency is identified from a stored table based on the indication of the second address of the message center in the short message and inserted in the short message for routing. To begin with respect to Figure 9, the mobile device 102 originates the communication of a short message through the wireless communication network (step 950 of Figure 9). The short message is indicated as an SMS originated by the mobile (MO) or "MO-SMS" in Figure 9. This short message may or may not be an emergency message.

The short message may be input to the mobile device 102, for example in any of the ways described above in relation to Figures 6-8. In general, the processor of the mobile device 102 identifies a request for user input from the user via the user interface to communicate the short message. The processor identifies whether the user's input request is for the emergency message, and this can be detected, for example, in any of the ways described above in relation to Figures 6-8. If the user's login request is identified as being a non-emergency message, the processor reads the first address of the message center from the memory and provides the first address of the message center in an address field of the message message center short. On the other hand, if the user's input request is identified as being an emergency message, the processor reads the second address of the message center from the memory and provides the second address of the message center in the address field of the message center. messages of the short message. In the present embodiment, the address field of the message center may be a Data Destination Address field per RP of the short message (see specification document TS 24,011, section 7.3.1.2). The short message is then transmitted through the wireless communication network in the air interface in step 950 of Figure 9. In general, when the short message is an emergency message, the second address of the message center in the short message is used by the network to identify that the short message is an emergency type. Based on identifying this address, the network essentially intercepts such a message and directs it to the appropriate local message center for handling and transmitting the emergency message to the appropriate emergency destination. When the mobile device 102 visits a non-local wireless network, this local message center is not the local message center of the local wireless network. Details are now described regarding the handling and network processing of the short message. The short message originated by the mobile device 102 is received and processed by any suitable network component or node, such as MSC 122 or SGSN 126. It should be noted that emergency short messages are processed by the network with a higher priority about and in advance of short messages of non-emergency type. Assuming the operation by the MSC 122, MSC 122 is operative to read the address of the message center, inserts it into an address field of the short message service center, and transmits the short message for further processing in the network. In this modality, the field of the service center is an OA field of Service Center Address of the SMS OPERATION of transmitting MO of TS29.002. In addition, the short message is transmitted to a Signaling Connection Control Part (SCCP), which may be a part of the MSC 122. In response to receiving the message, the SCCP operates to read the address of the service center from the transmitted short message and compares it with a stored address associated with the handling of the emergency message (see, for example, address 904 of the emergency SMS-SC of Figure 9). In this modality, the stored address is the same address or fixed indication for all carriers for messaging or emergency management (global or regional). It should be noted that, in this layer, the address of the message center of the short message can be called an E.164 Global Title Address. If there is a match between the address of the service center of the short message and the stored address, then the SCCP operates to replace the address of the message center with an address of the message center corresponding to a local message center (e.g. SMS-SC 306) assigned to process emergency messages. Again, it should be noted that short emergency type messages are processed over the network with a higher priority over and in advance of short non-emergency messages. Otherwise, the The message center address of the short message is not changed to the one corresponding to the local emergency message center. Alternatively, if a match exists based on the comparison, the SCCP operates to configure the destination (for example, Destination Point Code or DPC in the Message Transfer Part or MTP layer) to correspond to the local message center (for example, example, SMS-SC 306) assigned to process emergency messages; otherwise, the destination of the short message is not changed to correspond to the local emergency message center. Therefore, if the short message is of the emergency type, the short message is communicated from the SCCP and routed through the SMS intercommunicating with the MSC (SMS I MSC) 902 (step 952 of Figure 9) to the message center local (for example, SMS-SC 306) associated with the address of the message center (step 954 of Figure 9). The SMS-SC 306 can then appropriately route the short message to a local emergency destination 906 (police, fire, ambulance, etc.) (step 956 of Figure 9). When apparent, when the mobile device 102 visits a non-local wireless network, the local message center (e.g., SMS-SC 306) is in fact local and not the local message center of the local wireless network; therefore the emergency message is properly communicated to local authorities in or near the visited wireless network instead of the local authorities in or near the local wireless network. On the other hand, if the short message is non-emergency type, then the short message is communicated from the SCCP and routed through the SMS I MSC 902 (steps 952 of Figure 9) (or other SMS I MSC) to the center of local messages (e.g., SMS-SC 154) associated with the address of the message center (step 960 of Figure 9). The local SMS-SC 154 can then appropriately route the short message to a destination 908 as previously indicated by the user when the short message originated (step 962 of Figure 9). In a particular embodiment, the second address of the message center for emergency services may be regularly or periodically broadcast in a control or broadcast channel over the wireless communication networks for reception, storage, and use by mobile communication devices for such purposes. This is particularly useless when the second address of the message center represents the actual direct or indirect address of the local message center which handles the emergency messages. To illustrate, Figure 10 is a flow chart of the basic process for describing a method to be used in broadcasting emergency address information over the wireless network. As disclosed in Figure 10, broadcast information 1002, 1004, and 1006 is regularly or periodically broadcast by wireless network 304 to a specific repetition rate. The mobile communication devices operating in the wireless network 304, such as the regular mobile device 102 or periodically receive such broadcast information while it is stored in the memory. Since the wireless network 304 can change the emergency address or other information from time to time, most of the current broadcast information is always used by mobile devices for the processing of short messages. When the updated address information is received, the mobile device 102 operates to store the updated address information in order to thereby replace the information of the previous address. The second address of the message center can be stored in the memory of the mobile device by associating it with a wireless network identification of the wireless communication network. For example, the wireless network identification may be or include an identification of the PLMN, pairs of Mobile Country Code (MCC) and Mobile Network Code (MNC), or System Identifications (SID), etc. Table 3 below illustrates a way in which the second address of the message center can be stored in the memory (e.g., the removable memory module) of the mobile device: Table 3. Address Field for the Address of the Emergency Service Center Associated with the Wireless Network Identification. Therefore, the mobile device 102 can maintain the storage of the emergency message center addresses for a particular wireless network, and can store a plurality of such addresses associated with a large number of different wireless networks. Thus, when the mobile device 102 is roaming or visiting a non-local wireless network (e.g., wireless network 304), it can use the address of the emergency message center for that particular wireless network. The following Table 4 is an example which illustrates a format in which the address of the emergency message center can be broadcast on the control or broadcast channel over the wireless network: Table 4. Dissemination Information Which Includes the Emergency Address. In an alternative technique, a flag of the short message is configured to indicate that the short message is an emergency message instead of providing the second destination message in the address field of the message center. By using such technique, the address of the message center may remain as the address of the local message center or other suitable address before transmission from the mobile device. More explicitly, if the user's input request is identified as being an emergency message, the indicator in the short message is configured by the mobile device to indicate that the short message is an emergency message. On the other hand, if the user's input request is identified as being for a non-emergency message, the indicator in the short message is configured by the mobile device to indicate that the short message is not an emergency message. Preferably, the indicator is configured appropriately in a Transport Protocol Identifier (TP-ID) field of the short message. The indicator in the TP-ID to handle emergency messages can be provided as illustrated in the example below: Field of TP-ID Bits Description 543210 000000 Short Message Type 0 000001 Replace Short Message Type 1 000010 Replace Short Message Type 2 000011 Replace Short Message Type 3 000100 Replace Short Message Type 4 000101 Replace Short Message Type 5 000110 Replace Short Message Type 6 000111 Replace Short Message Type 7 001000 Emergency SMS (NEW) 001001..011101 Reserved Processing of the short message over the network can be done in the same way as previously described in relation to Figure 9, except that the MSC / SGSN operates to read the indicator from the transmitted short message and compare it with a stored indicator for the handling of emergency messages. If there is a match between the short message indicator and the stored indicator, then the MSC / SGSN operates to replace the address of the message center with a message center address corresponding to a local message center (e.g., SMS-SC 306) assigned to process emergency messages; otherwise, the short message is processed in a normal manner where the address of the message center (eg, address of the local message center) is left unchanged in the address field of the message center. Therefore, methods and apparatuses for being used by mobile communication devices for communicating emergency short messages via wireless communication networks have been described. In an illustrative example, a first address of the message center associated with a local message center and a second address of the message center associated with an emergency message center is stored in the memory of the mobile device. The memory can be a removable memory module, such as a Subscriber Identity Module (SIM), for the mobile device. A user's input request is received to communicate a short message through a user interface of the mobile device. If the user's input request is identified as being for an emergency message, the second address of the message center is read from the memory and is provided in an address field of the message center of the short message. He short message having the second address of the message center in the address field of the message center is then transmitted by the mobile device to the wireless network. The network identifies the second address of the message center in the address field of the message center and, in response, causes the short message to be sent to the emergency message center which is local to the network. In this way, when the mobile device visits a non-local wireless network, the short message can be routed to the appropriate local emergency message center. The mobile device can receive the second address of the message center in a broadcast channel of the wireless network and store it by associating it with a wireless network identification of the wireless network. In an alternative technique, an illustrative technique for being used by a mobile communication device when communicating a short message of emergency type by means of a wireless communication network involves the acts of receiving, through a user interface, a request for user input for communicating a cut message-providing a message center address corresponding to a local message center in an address field of the message center of the short message; if the user's entry request is identified as being for an emergency message: set an indicator in the short message to indicate that the short message is an emergency message; if the user's entry request is identified as a non-emergency message: configure the indicator in the short message to indicate that the short message is not an emergency message; and cause the short message to be transmitted to the wireless communication network. The indicator in the short message comprises a Transport Protocol Identifier (TP-ID). In another embodiment, an illustrative technique for use by a network node (such as a mobile switching center or GPRS Service Switching Node) when communicating a short emergency-type message from a mobile communication device through a network wireless communication involves the acts of receiving a short message having a destination address in a destination address field, a message center address in a message center address field which corresponds to a local message center, and an indicator in an indicator field which indicates whether the short message is an emergency message; cause the short message to be routed to the local message center based on the address of the message center if the indicator indicates that the short message is a non-emergency message; and cause the short message to be routed to an emergency message center different from the local message center if the indicator indicates that the short message is an emergency message. While the preferred embodiments of the invention have been described and illustrated, it should be understood that the invention is not so limited. Numerous modifications, changes, variations, substitutions and equivalents will occur to those skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
