The present invention relates to a method and system for calling a terminal using a mobile communication network. More specifically, a method for easily and quickly calling the other party by a simple operation of inputting the other party's telephone number to be called with a specific code on the keypad of the mobile communication terminal owned to call the other party; It's about the system.

As is well known, with the recent rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also wireless Internet access, video communication and video message transmission using mobile communication terminals. In addition, due to the rapid spread of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such as a considerable amount of contact generated through human communication.

Conventionally, a mobile communication terminal knows that even if a call connection attempt is made to a mobile communication terminal and the call connection is not successful until a predetermined time passes and the call connection attempt is completed, the user even knows that a call connection attempt is made to his mobile terminal. Could not. In order to compensate for the above disadvantages, when a call connection attempt fails, a service for simply providing a call connection attempt has been provided. For example, when five attempts to connect a call fail, a phrase such as “5 missed calls” is displayed on the mobile communication terminal to inform the user that there have been five call failures.                         

However, the service that provides only the fragmentary information that there have been several call connection failures does not provide any information about the caller. In order to solve this drawback, a caller identification service (CID) has recently been provided. Caller ID display service is a service that displays the caller's telephone number and the time the call was received on the called party's mobile terminal or display terminal before the call is initiated. By using the calling party number display service, the called party can grasp the phone number of the calling party and contact them.

Although there is a kind of calling method such as caller ID display service, the process of calling the other party using a mobile communication terminal is cumbersome and time consuming.

1 is a flowchart illustrating a process of calling a counterpart using a conventional mobile communication terminal.

In the process of calling a counterpart using a conventional mobile communication terminal, a caller first activates a message menu by operating a message button on a keypad of his mobile communication terminal (S100). Then, the caller selects a call menu by operating a key button on the activated message menu (S102), and inputs a call number which is a phone number of the other party by operating a key button (S104). When the caller completes the input of the call number and completes the input by pressing an input completion button, for example, a 'confirm' button, the mobile communication terminal outputs a screen for confirming whether to proceed with the call of the input call number (S106). When the caller inputs a key button for call progress on the output screen of step S106, the mobile communication terminal sends a call signal for the input call number to the mobile communication network to complete the call operation (S108).

Of course, there are some differences in the calling process according to the manufacturer of the mobile communication terminal, but in general, it is cumbersome to select a plurality of menus as described in FIG. There is a problem that takes a lot of time. Such a complicated calling method is not only troublesome and inconvenient for users who are familiar with the operation of the mobile communication terminal, but is also recognized as a serious problem that often occurs when the other party is not available to users who are not used to the operation of the mobile communication terminal. It is true.

The present invention is to solve the above-mentioned problem, the user to conveniently and quickly enter the other party's phone number to be called with a specific code on the keypad of the mobile communication terminal owned in order to call the other party conveniently and quickly It is an object to provide a method and system that can be called.

According to an object of the present invention for solving the above problems, a call system for calling a counterpart using a mobile communication network, comprising: a caller terminal for receiving a specific code and call number and transmitting a call; A mobile switching center receiving a call transmitted from the calling terminal through a wireless base station, determining that the call is a calling call, and generating and transmitting a call message transmission signal; An SMS server configured to receive the call message transmission signal, generate a call message, and transmit the call message through the mobile communication network; And a called terminal for receiving and outputting the call message from the mobile communication network.

According to another object of the present invention, a call method for calling a counterpart using a mobile communication network, comprising: (a) receiving, by a mobile base station, a call transmitted from an originating terminal through a wireless base station; (b) determining whether the received call is a call for invoking a called terminal; (c) generating and transmitting a call message transmission signal when it is determined that the call is made; And (d) receiving and outputting, by the called terminal, a call message through the mobile communication network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

2 is a simplified block diagram of a code based calling system 200 in a mobile communication network in accordance with a preferred embodiment of the present invention.

Code-based calling system 200 according to a preferred embodiment of the present invention is the source terminal 210, source wireless base station 220, source mobile switching center 230, home location register 240, SMS server 250 ), The short message service center 260, the called party mobile switching center 270, the called party wireless base station 280, and the called party terminal 290.

The calling terminal 210 is a terminal calling the called terminal 290 using a mobile communication network. Here, the mobile communication network is a communication network including the reference numerals 220 to 280.

Meanwhile, according to a preferred embodiment of the present invention, the method of calling the called terminal 290 by the calling terminal 210 is a code based method rather than a conventional menu based method. Here, the code-based method is a method of notifying a mobile communication network, especially a switch, that a call sent from the calling terminal 210 is a call for a specific purpose, not a normal voice call call. Therefore, in the code-based scheme, a specific code is added and sent to indicate a call for a specific purpose.

In the code-based calling system 200 according to the preferred embodiment of the present invention, the calling terminal 210 indicates that the call is a call prior to the telephone number of the called terminal 290 in order to call the called terminal 290. Assign a specific code to send a call. For example, according to an embodiment of the present invention, the call for the call sent from the calling terminal 210 may be configured in a format in which a specific code such as * 82 # precedes the call number. Therefore, the caller can call the other party by a simple operation of pressing the * 82 # and then inputting the telephone number of the called terminal 290. Of course, in the embodiment of the present invention, the specific code may be changed as much as possible.

In addition, the code-based calling system 200 according to an embodiment of the present invention provides not only an individual counterpart call but also a function of calling a counterpart on a group basis. In order to call the other party in groups, one or more group information is input to the calling mobile switching center 230 in advance to store the group data. Then, the caller can call one or more counterparts at the same time by entering a group call code and then entering a group number to call in succession. That is, according to an embodiment of the present invention, the personal call code and the group call code are set differently, in the case of a personal call, the "person call code + the other party's telephone number" is input, and in the case of a group call, the "group" Call code + group number "is entered.

The originating radio base station 220 generally performs functions such as mobility guarantee, handoff, and radio support management of the mobile communication terminal. This wireless base station comprises a base station transmitter 222 and a base station controller 224 and supports both synchronous and asynchronous. In this case, the base station transmitter 222 may be configured as a base transceiver station (BTS) and the base station controller 224 may be configured as a base station controller (BSC). In the case of asynchronous mode, the base station transmitter is a radio transceiver subsystem (RTS). The base station controller may be configured as a radio network controller (RNC).

The originating mobile switching center 230 performs basic and additional service processing, incoming and outgoing call processing of a subscriber, location registration procedure and handoff procedure, and interworking with other networks. In general, a mobile switching center in an Interim Standard (IS) -95 A / B / C system includes an Access Switching Subsystem (ASS) that performs distributed call processing, and an Interconnection Network Subsystem that performs centralized call processing. Subsystems include Central Control Subsystem (CCS), which is responsible for centralizing operations and maintenance, and Location Registration Subsystem (LRS), which stores and manages information for mobile subscribers.

Meanwhile, the calling mobile switching center 230 checks a specific code included in the call transmitted from the calling terminal 210 to determine whether the call is a voice call or a call including a personal call and a group call. . When the calling party exchange 230 determines that the received call is a calling call, one or more telephone numbers included in the individual and the corresponding group of the called party and the telephone number of the calling party terminal 210 are included in the call message transmission signal. Included and sent to the SMS server 250.

On the other hand, since the configuration and operation of the reference numerals 270 and 280 are the same as the source radio base station 220 and the source mobile switching center 230, a detailed description thereof will be omitted. In addition, in the embodiment of the present invention, for convenience of explanation, the calling party and the called party are divided and described as shown in FIG. 2, but the calling party and the called party may be changed depending on circumstances.

The Home Location Register (HLR) 230 receives location information of the mobile communication terminal from a Visitor Location Register (VLR) (not shown) that is generally installed in the mobile switching centers 230 and 270. It performs functions such as registration recognition, registration deletion, and location check. In addition, the home location register 230 stores profile information of the mobile communication terminal. Here, the profile information includes a mobile identification number (MIN), an electronic serial number (ESN), and subscribed mobile communication service information of the mobile communication terminal. Therefore, when providing a code-based calling service according to an embodiment of the present invention to registered subscribers only, the calling party mobile switching center 230 checks profile information stored in the home location register 230 and determines whether to provide the service. .

The short message service (SMS) server 250 receives a call message transmission signal from the calling mobile switching center 230, and generates a call message for each of one or more telephone numbers included in the received call message transmission signal. Transfer to the service center 260. Here, the call message generated by the SMS server 250 includes the telephone number of the calling terminal 210.

The Short Message Service Center (SMSC) 260 receives the call message transmitted from the SMS server 250 and transmits the call message to the corresponding called party terminal 290. Here, the short message service center 260 temporarily stores the received call message and transmits the call message to the called terminal 290 (Store and Forward). The short message service center 260 repeatedly sends the call message at predetermined intervals until the acknowledgment signal of the short message is received from the called terminal 290, and deletes the stored call message if the acknowledgment signal is transmitted. do.

3 is a flowchart illustrating a code-based call service process according to a preferred embodiment of the present invention.

A user who wants to call a specific counterpart or a plurality of counterparts simultaneously inputs a specific code and a calling number using the calling terminal 210 (S300). Here, the specific code and call number to be input will be different according to the private call and the group call. For example, in the case of a personal call, a code for a personal call and the other party's telephone number are input, and in the case of a group call, a code for a group call and a group number are input.

A user who inputs a specific code and a calling number consecutively sends a call by pressing a button having a confirmation function such as a "send" button on the keypad of the calling terminal 210 (S302). The call sent by the calling terminal 210 is received by the calling mobile switching center 230 via the calling wireless base station 220 (S304).

The calling mobile switching center 230 that receives the call transmitted from the calling terminal 210 determines whether the received call is a call based on a code according to an embodiment of the present invention (S306). Here, the originating mobile switching center 230 checks a specific code included in the received call to determine whether the call is a call.

If the calling mobile switching center 230 determines that the call is a call as a result of the determination in step S306, the calling mobile switching center 230 generates a call message transmission signal and transmits it to the SMS server 250. In more detail, when it is determined that the received call is a group call, the calling mobile switching center 230 checks the telephone number of at least one called terminal 290 included in the received group number and transmits a call message transmission signal. Create Here, the call message transmission signal transmitted by the calling party mobile switching center 230 includes a phone number of the calling party terminal 210 and a phone number of one or more called party terminals 290.

Of course, the calling party mobile switching center 230 processes the corresponding service if it is determined that the call is not a call for determining in step S306. For example, the originating mobile switching center 230 processes voice calls or data communications.

Upon receiving the call message transmission signal from the calling mobile switching center 230, the SMS server 250 generates a call message for each called terminal 290 and transmits it to the short message service center 260 (S312). Upon receiving the call message, the short message service center 260 transmits each call message to the corresponding destination terminal 290 through the mobile communication network. The called terminal 290 receives and outputs an incoming message transmitted through the mobile communication network (S314).

The above description is merely illustrative of the present invention, and those skilled in the art will appreciate that various modifications can be made without departing from the essential features of the present invention. Accordingly, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments. It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto shall be construed as being included in the scope of the present invention.

As described above, the call of the other party using a conventional mobile communication terminal is cumbersome and complicated to use in a menu-based manner, while the code-based calling service according to an embodiment of the present invention directly uses a corresponding code without going through a complicated menu selection step. There is an advantage that it is convenient and quick to use because it is called by input.                     

Therefore, in the conventional menu-based method, it is possible to provide a familiar and simple calling service to users who are not familiar with the operation of the mobile communication terminal, thereby improving service quality and functioning as a new communication revenue source. .
