Abstract

Apparatus, and an associated method, for facilitating call connection with a selected service center from a mobile node. A mobile node is provided with short dialing codes used in a network with which the mobile node is registered by SMS messages sent thereto, such as pursuant to registration procedures. Values of the short dialing codes downloaded to the mobile node are stored at a storage location, such as at a SIM card, indexed together with corresponding codes normally used by a user of the mobile nodes, such as the codes used in the home network of the mobile node. When a user places a call to a service center, the stored values are retrieved, and transposed, if needed, to ensure better that the call to the selected service center is successfully completed.

Description

APPARATUS AND ASSOCIATED METHOD TO FACILITATE THE GENERATION OF A CALL CONNECTION IN A RADIO COMMUNICATION SYSTEM WITH A SERVICE CENTER IDENTIFIED BY A CODE OF SHORT MARKING BACKGROUND OF THE INVENTION The present invention generally relates to a way to facilitate the generation of a call connection originated by a user of a mobile node placed at a service center that can be identified by a short dialing code, such as a dialing code 9-1-1 or 9-9-9. More particularly, the present invention relates to an apparatus, and an associated method, by which the dialing digits entered by the user are allowed to be transferred to dialing digits used to identify a selected service center in the network at the which mobile node is registered, thereby allowing a call connection to be formed with the service center. Many aspects of modern society require the use of modern communication systems through which to communicate information to carry out a communication service. Many different types of communication systems have been developed to enable the realization of many different types of communication services. Scientific discoveries and technological advances have allowed, and continue to allow them to develop and deploy new types of communication systems. New communication systems generally allow information to be communicated at high speeds and from, and between, locations in which communications have not previously been available. Among the advances that have been adapted for use in many modern communication systems are advances in digital communication technologies. The use of digital communication techniques provide several advantages, mainly those related to the ability to provide improved communication efficiencies in the communication system in which digital communication techniques are used. And, the information, once digitized, can communicate during discrete intervals. A radio communication system is an exemplary type of a communication system. The information is communicated between the communication stations of a radio communication system over radio communication channels defined over a portion of the electromagnetic spectrum. Many radio communication systems make use of digital communication techniques to make communications between the radio communication stations operable in them. Due to the limitations of broadband regularly associated with radio communication systems, the use of communication techniques digital is particularly advantageous when they are adapted for use in a radio communication system. Radio communication systems provide several advantages in contrast to cable-connected equivalents. For example, the costs associated with the installation and initial deployment of a radio communication system are generally less than the corresponding costs required to install and deploy a wired equivalent. And, a radio communication system is suitable for implementation as a mobile communication system. In a mobile communication system, the mobility of communications is provided to one or more communication stations. A cellular communication system is a type of radio communication system. The network infrastructures of successive generations of cellular communication systems have been installed over significant portions of populated areas of the world. And, those systems have achieved significant levels of use. Although the types of communication services that can be performed by means of a cellular communication system are increasing, cellular communication systems are still used, in significant parts, to perform a telephone communication of voice information. Telephone communications are made, typically, in a cellular communication system through the use of a mobile station. A mobile station is a portable radio transceiver, typically of dimensions that allow it to be carried in the hand by a user. The user purchases the access to communicate through the mobile station through the communication system or purchase access to the system. A GSM cellular communication system (Global System for Mobile Communications) is an example of a cellular communication system that uses digital communication techniques. The GSM system operates according to the standards and protocols established in an operational specification promulgated by the ETSI (European Telecommunications Standards Institute). The GSM system defines a communication scheme that uses a combination of frequency division multiple access (FDMA) and time division multiple access (TDMA) communication schemes. Networks built to operate in accordance with the GSM system's operational specification have been installed throughout many areas. And, the GSM system has become one of, if not the, type of dominant cellular communication system in the world. A cellular communication system IS-95 (Interim Standard 95) is another exemplary cellular communication system. An IS-95 system using a CDMA communication scheme (multiple access by code division). And the operating standards for a UMTS system (universal mobile phone service) are undergoing developments. The mobile stations that are operated in a GSM system, as well as other mobile stations, are constructed, typically to mimic the operation of conventional telephone stations. That is, mobile stations are typically operable to both originate and terminate telephone calls in the ways that correspond, at least from the user's perspective, to ways in which conventional telephone stations are used to originate and terminate telephone calls. Calls placed elsewhere end in the mobile station through the generation of a call connection, and calls originating in the mobile station for termination elsewhere by means of a call connection. According to the placement of the call, the signaling is generated with the mobile station according to a procedure for initiating a call. When a call is terminated at a mobile station, an alert is generated, such as a ring tone, on the mobile node as part of the startup procedure. The alert alerts the user of the mobile station of the call placement of the mobile station. And, the user of the mobile station allows the generation of the call connection with the acceptance of the call in response to the alert. The call is accepted in an analogous manner in the manner by which the user of the device connected by conventional cable takes a station connected by busy cable. When a call originates in the mobile station, the user initiates the origin of the call by entering the dialing digits that identify the terminating station, ie, the called party, in which the call is placed or terminated. . Once the dialing digits have been entered, the call signal procedures are performed to initiate the call. The call signaling procedures are generally transparent to the user. Short codes are sometimes used to identify certain designated service centers in some areas. That is, the short dialing codes identify the designated service centers. In the United States, for example, some areas have 9-1-1 emergency services centers. Sometimes it refers to code 9-1-1 as an emergency number. A person who places the order for emergency assistance enters the 9-1-1 code into a telephone station. The call is routed to an appropriate 9-1-1 service center. The 9-1-1 service center provides the facilities for a quick response to the call. But in other areas, different codes are used apart from code 9-1-1, to identify the emergency service center. For example, in the United Kingdom, an emergency service center is accessed by telephone from a telephone station by entering a code 9-9-9. Short-dial codes are sometimes also used to identify other service centers. For example, directory service centers are accessed by telephone in some areas of the United States through the entry of code 4-1-1. In parts of the United Kingdom, a directory service center is accessed by telephone by entering a code 1-9-2. Likewise, in an analogous manner, the assistance of the operator is accessed by telephone in some areas through the entry of the dial digit ^ 0 '. In some other areas, the assistance of the operator is accessed through the entry of a short code 1-0-0. A user of the mobile node is generally aware of the short dial digits that identify the service centers selected in the area in which the user of the mobile station is accustomed. However, due to the inherent mobility of the mobile node, the mobile node may be located in an area that uses other dialing digits to identify the service centers selected than the dialing digits with the which the user is used to. For example, the user of the mobile node may be accustomed to dialing digits 9-1-1 to identify an emergency service center. But the user, together with the mobile station, may be located in an area in which other dialing digits are used, such as dialing code 9-9-9 to identify the emergency service center. If the dialing code is associated with a service center that the user of the mobile station attempts to call differs from the dialing code that is used in the area from which the call is placed, the call is not routed to the appropriate service center . Therefore, a way is needed to better provide the placement of a call from a mobile station to a service center identified by a short dialing code. That is, a way is needed to take into account the inherent mobility of a mobile station so that a service center that is accessed through the entry of short dialing digits by a user of a mobile station remains accessible without having Consider the position of the mobile station when placing the call to a service center. In view of this background information related to the placement of a call from a call to a service center by means of a communication system of radio is that significant improvements have been developed to the present invention. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 illustrates a functional block diagram of a radio communication system in which one embodiment of the present invention is operable. Figure 2 illustrates a representation of the stored dialing codes according to the operation of one embodiment of the present invention and the indexing together with it also according to the operation of one embodiment of the present invention. Figure 3 illustrates a sequence message diagram representative of the signals generated during the operation of an embodiment of the present invention. Figure 4 illustrates an exemplary message generated during the operation of an embodiment of the present invention by which to provide a mobile node with short dial code indications in an area in which the mobile node is positioned. Accordingly, the present invention advantageously provides an apparatus, and an associated method, by which to facilitate the generation of a call connection of a call originated by a user of a mobile node placed at a service center and identifiable by a user. short dialing code, such as dialing code 9- 1-1 or 9-9-9. Through the operation of one embodiment of the present invention, a way is provided by which to allow the dialing digits entered by a user to be transposed into dialing digits used to identify a selected service center. A call connection is generated even if the short dialing code used in the network in which the mobile station is traveling differs from the dialing code normally used by the user to originate a call to the service center. In one aspect of the present invention, the short dialing codes that identify service centers in the area in which the mobile station is positioned are downloaded to the mobile station once the mobile station registers with the network. When the mobile station enters another area that needs a renewed registration, the short dialing codes are again downloaded to the mobile station, so that the values of the current short dialing codes are stored and maintained in the mobile station. The user of the mobile node needs to be aware of the short dialing codes with which the user is normally associated, or otherwise cause the entry of the dialing digits, such as by means of a speed dialing procedure. That is, the digits of Dialing normally used by the user continue to be used to identify the service center once the origin of a call to a service center has started. However, the entered digits are transposed, if necessary, to the mobile node in a number that allows the call connection to be generated. In another aspect of the present, the downloaded short dialing codes that are downloaded to the mobile node, such as during the registration of the mobile node, are stored in the mobile node. Subsequently, when a user of the mobile node initiates the origin of a call to a selected service center, the dialing digits entered, or caused to enter, by the user are indexed together with the corresponding values downloaded to the mobile node. The corresponding value, that is, the values corresponding to the entered values, are replaced by the dialing digits entered, and the call is placed at the call station identified by the substitution dial digits. That is, the dialing digits entered are transposed into other dialing digits to allow the end of the call. In another aspect of the present invention, the dialing digits downloaded, downloaded to the mobile node, are stored in a storage element that allows updating the contents of the memory thereof. In a GSM cellular communication system, or other analog, using SIM (Subscriber Identity Module) cards, the short dial codes downloaded are stored in a SIM card of the mobile node. When a call to a service center is initiated later, the dialing digits entered associated with the initiation of the service call origin are indexed together with the corresponding values stored in the SIM card. The corresponding values are replaced by the entered values, and the call is placed in the service center using the appropriate dial digits for the area in which the mobile node is positioned. In an IS-95 or other analog cellular communication system using R-UIM cards, short dialing codes are stored in the R-UIM (Removable User Identification Module) card of the mobile node. In one implementation, according to the registration of the mobile node with the network, a message of the SMS (Short Message Service) is sent to the mobile node. The SMS message is generated, for example, from an Envelope command message in which the short dial digit used to identify the service centers in which the mobile node is positioned is encapsulated therein. When received in the receiving part of the mobile node, the SMS message is sent to the SIM card, and the encapsulated values are stored in the SIM card. When the mobile node is subsequently re-registered, another SMS message is downloaded to the mobile node, and the updated values of the dialing codes are stored over the dialing codes existing in the SIM card. Therefore, the user of the mobile node is able to originate a call to a selected service center using the short dial digits known to the user. The replacement of the short dialing digits used in an area in which the mobile node is positioned is performed to allow the call connection of the call to the appropriate service center. The delayed call connection, or failure to generate call connections, is less likely to occur through the operation of a modality of the present invention. Therefore, in these and other aspects the apparatus, and the associated method, is provided for a radio communication system having a mobile node operable by a user to communicate with a part of the network of a communication network. At least one first service center is coupled to the network part. A call originated by the user in the mobile node is selectively routed to at least one first service center selected to generate a call connection between them. It facilitates the routing of the call to, at least, the first center of selected service. A first storage element stores first values that identify, at least, the first service center. One of the first selected values is used by the user of the mobile node when initiating the origin of the call to at least one first selected service center. A second storage element stores second values that identify at least the first service center. The second values are used in a part of the network of the communication network in which the mobile node is registered in the present. An indexer is coupled to the first stored element and the second stored element. The indexer indexes together one of the first selected values when it is used by the user initiating the origin of the telephone call, to one of the corresponding second values. Referring first to Figure 1, a mobile communication system, generally shown at 10, provides communications with mobile nodes that allow mobility at least in the entire area covered by the communication system. In the Figure a representative mobile node 12 is shown. In the exemplary implementation, the communication system generates a multiple user system that allows a plurality of concurrent communication sessions with a plurality of mobile nodes. The additional mobile nodes can also be represented in the Figure, analogous to the representation of the mobile node 12 to represent other mobile nodes with which communication sessions are carried out. In the exemplary implementation shown in the Figure, the communication system 10 generates a cellular communication system that operates, in general, in accordance with the parameters and operating protocols established in a GSM operating specification (Global System for Mobile Communications) . In other implementations, the communication system is representative of cellular communication systems operable according to other operation specifications, such as the IS-95 system mentioned above or a UMTS system. And, more generally, the communication system is representative of any of the various types of radio communications that provide telephone communications. Accordingly, although the exemplary operation of a modality of the present invention will be described with respect to its implementation in a cellular communication system operable in accordance, generally, with a variant of a GSM operation specification, in other implementations, the of the present invention are analogously operable in any of the various radio communication systems. The communication system includes a portion of the fixed network with which the mobile node 12 communicates. The communications are made between the part of the network and the mobile node by means of radio channels defined on radio links that extend between the part of the network and the mobile node. The data communicated by the network part to the mobile node communicates on downlink channels defined on a radio downlink. And, the data communicated by the mobile node to the part of the network communicates on uplink channels defined on a radio uplink. Here, the downlink is represented by the arrow 14 that extends between the part of the network and the mobile node. And, the uplink is represented by the arrow 16 that extends between the mobile node and the network part. Both, the control data and the traffic data are communicated over several channels defined on the downlink and the uplink. The network portion of the communication system is shown, here, to include two GSM networks, a first GSM network 18 and a second GSM network 22. The networks 18 and 22 are connected together, in a conventional manner, by means of a signaling network, here a signaling network 24 SS7. Other signaling networks, in other implementations, interconnect networks 18 and 22. For example, in another implementation, an X.25 network interconnects GSM networks 18 and 22.

Each of the GSM networks 18 and 22 are operated according to a variant of the GSM operation specification. Each of the networks is generated from radio network elements that allow telephone communication with the mobile station 12 when the mobile station is positioned within the coverage area encompassed by the separate networks. Each network includes, for example, a base transceiver station 26 (BTS) and a base station controller 28 (BSC) coupled thereto. The base transceiver station includes a radio transceiver circuitry for transmitting and receiving data communicated over the downlink and uplink channels to the mobile stations, such as the mobile station 12. The base station controller, on the other hand, is coupled to a mobile switching center / visited location register (MSC / VLR) 32. A local location register (HLR) is also shown to generate a portion of each of the networks of GSM, functionally coupled to a mobile switching center / associated visited location register. Each of the networks 18 and 22 also includes a center 38 (SMS-C) of short message services (SMS). Each of the short message service centers is operable to generate SMS messages and selectively send SMS messages to mobile stations, such as mobile station 12. Of particular significance for an embodiment of the present invention, the SMS center sends SMS messages selected according to the registration of a mobile node with which the short message service center is associated. The network 24 SS7, or another analogous network, which interconnects the networks 18 and 22, generates a signaling network to provide signaling connections, and others, between the networks. The signaling network here is also shown to include a switching node that generates a signaling transfer point (STP). Other types of networks, other than GSM networks 18 and 22, are also connected to the 24 SS7 network. A public switched telephone network or an integrated services digital network, for example, are each also connected to the SS7 network. An exemplary service center, here a service center 44, is functionally coupled to the SS7 network. The service center 44 is connected, for example, by means of a public switched telephone network or a digital network of integrated services to the SS7 network. A service center is, alternatively, connectable to the network part of the communication system in another location or through another connection. The service center 44 is representative of any call location identified by a coded sequence of digits. More particularly, here, the exemplary service center is representative of a call location identified by a first short code in the first network 18 and identified by a second code in the second network 22. The service center 44 is representative, for example, of an emergency dispatch center. As previously noted, the emergency dispatch center is identified, in different areas, by different short marking codes. In one area, for example, the center is identified by the short dial code 9-1-1. And, in another area, the service center is identified by the short dialing code 9-9-9. Alternatively, the service center 44 is representative of, for example, a directory service center. In some areas, the directory service center is identified by a first short dialing code, such as 4-1-1. And, in other areas, the directory service center is identified with a second short dialing code, such as 1-9-2. And, the service is also representative, alternatively, of an operator assistance center that, for example, is identified by the dialing code of? 0 'and in other areas, by the dialing code of 1-0-0. Other various service centers are also represented by the exemplary service center 44, accessible by telephone by entering an appropriate short dialing code. A call connection is generated with the service center through procedures to initiate a call when a call originates from a call station origin, such as the mobile node 12. The mobile node includes, in a conventional manner, a user interface that typically includes a telephone keypad operable by a user to initiate a telephone call, such as a call to the service center. In the Figure, the mobile node is shown to include a user interface 48, generated from a user input driver 50 and a user screen 52. When a user of the mobile node initiates a call to a selected service center, the user activates the keys of the telephone keypad and enters the dialing code associated with the user of the mobile node attempting to communicate by telephone according to a generated call connection. with a call station. And, more particularly, here, when the user attempts to place a call to the service center 44, the user enters the short dialing code associated with the service center. Because the short dialing code associated with the service center may differ, depending on which network the mobile node is registered, the proper routing of the call to the service center, to allow a call connection to be generated with it requires that the dialing digits used in the network be used, through which the mobile node communicates when it requests the call. The operation of a modality of this invention provides a way by which to better ensure that the correct short dialing code is used when a call connection is requested to be generated with a service center. And, according to one embodiment of the present invention, the mobile node includes an apparatus 58 of one embodiment of the present invention. When a mobile node is initially powered on, it enters the coverage area of a network, such as networks 18 or 22, and at additional selected intervals, the mobile node registers with the network part of the communication system. Several conventional methods are carried out by the communication system according to the registration of the mobile node, including, for example, the authentication of the mobile node to communicate by means of the part of the network of the communication system. Additionally, according to one embodiment of the present invention, during the registration procedures, the SMS service center of the network with which the mobile node is registered generates and causes an SMS message to be communicated to the mobile node. The SMS message includes values that identify the short dialing codes used in the network to identify the selected service centers. Therefore, the mobile node is provided with the short dialing codes used in the network to which the mobile node registers. The information contained in the SMS message is then used by the node mobile when a call is placed to a selected service center. The elements of the apparatus 58 incorporated into the mobile node are functionally represented. And, the functions carried out by the functional elements are carried out in any desired manner such as, for example, by algorithms executable by the processing circuitry. The apparatus 58 shown here includes an SMS message detector 62 that is coupled to, or part of, the receiving circuitry of the mobile node. The SMS message detector operates to detect the SMS message sent to the mobile node. The detections made by the detector are provided to the indexer 64. The indexer 64 is also part of the apparatus 58. The indexer includes, or is coupled to, a storage element 66. The indexer 64 operates to index values of id codes downloaded to the mobile node as part of the SMS message sent during the registration procedures and detected by the detector 62 together with the permanently stored values of the identification codes that are associated with the mobile node or the user thereof, with the service centers. The permanently stored values are those, for example, of the local network in which the mobile node is normally registered. Indexing the values stored permanently with the downloaded values generate an association between the separated values, allowing to compare the values and the use of the appropriate values when a call is subsequently placed at a selected service center. The values, indexed together, are stored in the storage element 66. In the exemplary implementation, the storage element is incorporated into a SIM card. In an IS-95 system that uses R-UIM devices, the storage element is incorporated into it. The values are available for later retrieval when a call is subsequently placed on the mobile node to a selected service center. In the exemplary implementation, the values remain stored in it until a later registration, and the subsequent download of an SMS message alters the values. Therefore, the values of the short dial digits are used in the network with which it is registered, the mobile node is updated, as necessary, to ensure that the dialing codes used in the network are always available in the node mobile. The apparatus 58 further includes a transponder 72 which engages both the indexer and the user input driver 50 of the user interface 48. When a call is placed by a user of the mobile node to a service center, the transponder realizes the placement Of the call. That is, when the user enters a shortened dialing code that the user associates with a service center, the values entered by the user are provided to the transponder. And, in response to the code entered, the transponder operates to transpose the values entered with the values stored in the storage element 56 if the values differ. The surrogate values are then provided to the transmitting part of the mobile node, and the normal calling procedures are used to place the call to the service center. A call connection, which would not otherwise be made to the selected service center, is generated through the operation of the apparatus 58. And, the services, then, are capable of being provided by the service center. The transposition of the short dialing code entered in the dialing code necessary to generate the call connection in the area comprised by the network with which the mobile node is registered is carried out automatically, without the need for the user to know about the transposition of the dialing codes. Figure 2 illustrates a representation, shown generally at 76, representative of the dialing codes stored in the storage element 66. A first set of codes is designated in column 78 as the codes of the permanent service center that are used in the local network associated with the mobile node. And, a second set of codes, indicated in column 82, is used in the network with which the mobile node is registered, downloaded to the mobile node according to the registration procedures, to be stored in the storage element, and dynamically updated as appropriate. Each of the codes is identified with a purpose, represented here by the revenues in column 84. In the exemplary implementation in which the mobile node generates a GSM mobile terminal, the storage element 66 is incorporated into the SIM card of the GSM. mobile node. In an alternative implementation, the SMS message that is delivered to the mobile node is used to generate a database of all the networks in which the mobile node can be moved. In this implementation, the SMS message does not need to be delivered to the mobile node with each registration of the mobile node in a new network. In such an implementation, additional storage capacity is required in the SIM for storage of the information lists. Figure 3 illustrates a message sequence diagram, generally shown at 92, representative of the operation of the communication system 10, shown in Figure 1 according to the operation of one embodiment of the present invention. Again, the operation is described with respect to an implementation in which the system of communication generates a GSM system. The analogous operation can be described with respect to the system that is operable according to another operation standard. The mobile station initiates registration with the network, here, the network 18, and the registration procedures are carried out, as indicated by segment 94. And, as indicated by segment 96, mobile originating USSDs are generated by the mobile node and sent to the wireless network. The wireless network, in turn, sends over a request for operator specific short codes, indicated by segment 98, which are delivered to the USSD service center. The codes are retrieved and returned, indicated by segment 102, to the SMS center. The SMS center, in turn, generates an SMS message, indicated by segment 104 that contains the operator-specific short codes of the service centers. An SMS message, indicated by segment 106, is sent on a radio downlink channel, to be delivered to the mobile node. In the exemplary implementation, the SMS message is a wraparound message that passes through the reception circuitry of the mobile node to storage, here the SIM card. The sending of the encapsulated message is indicated by the segment 108. When the information is stored in the SIM card, a response is provided from the terminal, indicated by the segment 112. The mobile node is able to access the contents of the card SIM, here indicated by segment 114. The sequence diagram of the message also illustrates the return of a completed mobile response, indicated by segment 116, sent by the mobile node to the wireless network 18, and an acknowledgment message is passed on. receipt, indicated by segment 118, to the SMS center and, as indicated by segment 122, to the USSD server. Then an acknowledgment of the short codes specific to the operator of the request, indicated by segment 124, is returned to the wireless network and, in turn, to the mobile device, indicated by segment 126. Figure 4 illustrates another diagram of message sequence, generally shown at 132. The sequence diagram 132 of the message is representative of an additional operation of the communication system according to an embodiment of the present invention. First, and as indicated by segment 134, the records of the mobile node are carried out with a wireless network, here again the wireless network 18, and the convention registration procedures. Then, and as indicated by segment 136, an initial DP is sent by the wireless network to the communication server. A command, indicated by segment 138, is returned to the SMS service center to send codes to the mobile station. And, as indicated by segment 140, a specific short code message is provided from the operator of download to the wireless network, and the message of short message services is sent, as indicated by the segment 142 to the mobile node. An encapsulated SMS message is sent by the mobile node to the SIM card, indicated by the segment 144. A response is provided from the terminal, indicated by the segment 146. From then on, a procedure for obtaining the data is carried out. response, indicated by segment 148. A mobile terminated response is generated and sent, indicated by segment 152 to the wireless. Messages are sent, indicated by segments 154 and 156, to server c. A subsequent file change notification message, indicated by segment 158 is selectively provided by the SIM card to the structure of the mobile node. The foregoing descriptions are of preferred examples for implementing the invention, and the scope of the invention should not necessarily be limited by this description. The scope of the present invention is defined by the following claims:
