The present invention relates to a mobile communication terminal, and more particularly, to an automatic number conversion method in a dual mode mobile communication terminal.

In WCDMA IMT-2000, subscribers are assigned two numbers. An International Mobile Subscriber Identity (IMSI) number on a USIM card and a Mobile Subscriber ISDN (MSSISDN) number on a terminal. The IMSI number is a 15-digit unique number assigned to a mobile communication terminal at the time of subscription. This number is unique worldwide (used for international roaming services). The 15-digit number consists of a mobile country code (3 digits), a mobile network code (2 digits), and a mobile subscriber identification number (10 digits). Telephone number in GSM network means MSISDN number and consists of country code, network code and directory number.

The Dual SIM card, which is provided by the GSM network, allows users to switch between two phone numbers. In this case, the two phone numbers are fixed values on the SIM card. If the user wants to change the number to the third number, the user cannot change it, so the purpose of Dual SIM is not 100% saved. For this reason, if you want to change the number is a inconvenience to buy a new SIM card. In the case of the existing dual SIM, two MSISDN information is read from the SIM card and two IMSI values are matched one-to-one to provide only two numbers to the user. However, this number is not easy to change, so when the user wants to change the number, there is a problem that you need to purchase a new SIM card, or update the MSISDN and IMSI value using a service center.

The present invention has been made to solve the above problems, and an object thereof is to provide an automatic number conversion method of a dual mode mobile communication terminal. If you want to change the phone number of the dual-mode mobile communication terminal, use the STK (SIM Tool Kit) to send the desired number (MSISDN) to the mobile network and receive new IMSI and MSISDN information through SMS and update it to the SIM card. Allows you to use a phone number (MSISDN).

According to an aspect of the present invention, there is provided a mobile communication terminal having a subscriber identity module (SIM) card, the method comprising: generating a message including call activation information of the terminal; Sending the message; Receiving a registered call activation message from a mobile communication network; And storing the message.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a broadband communication network for dual SIM automatic number conversion according to the present invention.

In a broadband communication network (GSM), there is generally a Subscriber Identity Module (SIM) that can be plugged in and disconnected from a mobile communication terminal. The SIM stores information about a particular user. SIMs have a well-defined limited functionality, and network side visitor location registers (VLRs) and home location registers (HLRs) can interoperate different types of SIM cards. The dual-mode mobile communication terminal includes a controller (MSC, VLR, HLR, etc.) coupled to the wireless transceiver for bidirectional communication with one of a number of different networks, such as GSM networks and Universal Mobile Telecommunications System (UMTS) networks. do. Here data storage modules such as SIM / USIM or UICC (UMTS integrated circuit card) are readablely coupled to the controller. The module then stores information that specifies the scope of module operation in each of an identifier and a number of different networks. The Home Location Register (HLR) is a database that contains semi-permanent mobile subscriber information. The subscriber information of the home location register includes the International Mobile Subcriber Identity (IMSI), the information on the recent visit location registration, and the service limitation and sufficient information on the routing of the call during the mobile terminal period. The Visitor Location Register is a database that registers the location of a terminal outside the home exchange center (MSC). The terminal frequently announces its location through the nearest base station, and the VLR is registered with the base station ID closest to the terminal. The visitor locator (VLR) attempts to exchange messages between the switching centers (MSCs) and track them to send the messages to their destinations, as well as long distance connections for normal connectivity. When the terminal is outside, the MSC sends a message to the HLR to which the subscriber belongs by using routing information (tracking route) stored in a signaling transfer point (STP). Signaling System 7 (SS7) Gateway is a communication protocol that shifts the burden of PSTN data traffic congestion to a broadband communication network. It is responsible for basic call setup, management and release, wireless roaming, and wireless subscriber authentication. The authentication center (AuC) verifies the validity of the subscriber using the received IMSI and checks the availability of the terminal using the Electronic Serial Number (ESN). The parameters required for authentication are transmitted between the network and the terminal. If the data that is shared match, the service request is accepted.

In step S200 check if there is a NEW MSISDN (telephone number) registration menu selection key input. If there is a corresponding key input, the SIM Tool Kit (STK) program is driven (S201). The SIM Tool Kit (STK) is a program applied to a SIM card and displayed on the terminal as a menu item. STK is an application program interface that allows a SIM card to issue commands to a terminal, the scope of which performs menu display, user input acquisition and SMS message transmission and reception. The most important features include user authentication and security commands in the form of SMS, including IMSI and MSISDN numbers. In step S202, a new MSISDN number is received by a new number assignment module (NAM). The new MSISDN information is transmitted to the broadband communication network using the STK (SEND_SMS) command (S203). The IMSI and MSISDN are searched for based on the SMS information received from the broadband communication network, and it is determined whether or not registration is possible (S204). At this time, if the requested number is busy or unavailable, a Reject message is received (S205), and a registered IMSI and MSISDN number are received from the home location register (HRL) of the broadband communication network (S206). Receive new MSISDN and IMSI in STK (SMS_PP_DOWNLOAD) format and store in SIM card memory area. At this time, the SIM card automatically updates the registrant information (S207). In addition, the number registration result is displayed on the display using the DISPLAY_TEXT command. The REFRESH (Reset) _STK command is used to update the MSISDN and the IMSI number from the authentication center (AuC) of the GSM network (S208). In step S209, a new telephone number (MSISDN) setting is completed.

3A and 3B are exemplary views illustrating a dual SIM automatic number conversion registration process according to an embodiment of the present invention.

<HLR # 1> registers IMSI numbers from 310-68-4451000 to 310-68-4451005 from two other MSCs. <HLR # 2> is a case where an IMSI number is given in the range of 310-68-5568095 to 310-68-5568100 from two identical MSCs according to a new number request. At this time, the mobile number IMSI = 310-68-5568099 is requested from <HLR # 2> to <HLR # 1>. <STP # 1, # 2> classifies home location register according to IMSI number classification. In <MSC # 1> and <MSC # 2>, call call routes by MSISDN and HLR are determined. The MSISDN of the mobile number = 415-387-8884 is registered in <HLR # 1> and is confirmed as the <MSC # 2> path. At this time, the mobile number MSISDN = 415-387-8884 is stored in <HLR # 1> and transmits the number to the dual mode mobile communication terminal.

4 is a block diagram showing an International Mobile Subscriber Identity (IMSI) number consisting of 15 digits.

The IMSI number is a 15-digit unique number assigned to a mobile communication terminal at the time of subscription. This number is unique worldwide (used for international roaming services). The 15-digit number consists of a mobile country code (MCC: 3 digits), a mobile network code (MNC: 2 digits), and a mobile subscriber identification number (MSIN: 10 digits).

As described above, the present invention enables the user to input the MSISDN as an automatic number conversion method in the dual mode mobile communication terminal and receive the IMSI and MSISDN authentication from the broadband communication network, thereby enabling the phone number to be used more efficiently.
