본 발명은 이동통신단말기에 관한 것으로, 특히 네트웍 위치등록시 이동통신단말기의 IMSI 재생(Refresh) 방법에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to an IMSI refresh method of a mobile communication terminal when registering a network location.

종래의 3GPP(3rd Generation Partnership Project)의 USIM(User Service Identity Module) 규격에는 IMSI 재생(Refresh)에 의하여 USIM은 단말에 두개 이상의 IMSI를 번갈아 활성화(Activate)할 수 있다. 그러나 IMSI 재생(Refresh)이 단말과 어떻게 연동하여 효율적인 서비스를 제공할 수 있는지는 언급되지 않는다.According to the USIM (User Service Identity Module) standard of the 3rd Generation Partnership Project (3GPP), the USIM may alternately activate two or more IMSIs in the terminal by IMSI refresh. However, it is not mentioned how IMSI Refresh can provide an efficient service in conjunction with the UE.

상술한 바와 같은 문제점을 해결하기 위하여 본 발명은, IMSI 재생(Refresh)과 통신 Network Selection관점에서 2개 이상의 IMSI가 있는 USIM에서 효율적인 네트웍 위치등록 방법을 제공하는데 그 목적이 있다.In order to solve the above problems, an object of the present invention is to provide an efficient network location registration method in a USIM having two or more IMSIs in terms of IMSI refresh and communication network selection.

이상과 같은 목적을 달성하기 위한 본 발명의 특징은, 국제이동가입자식별(IMSI)번호 2개의 모드를 가지는 이동통신단말기에 있어서 활성화된 IMSI 1모드로 통신네트웍에 위치등록 메세지를 송신하는 단계; 상기 통신네트웍으로부터 위치등록 거부 메세지를 수신하는 경우, 상기 단말내 IMSI 재생(Refresh)에 의해 IMSI 2가 활성화 되는 단계; 상기 활성화된 IMSI 2모드로 통신네트웍에 위치등록 메세지를 송신하는 단계 및 상기 통신네트웍으로부터 위치등록 메세지를 수신하는 단계를 포함하는데 있다.A feature of the present invention for achieving the above object comprises the steps of: transmitting a location registration message to a communication network in an IMSI 1 mode activated in a mobile communication terminal having two modes of mobile subscriber identity (IMSI) number; When receiving a location registration rejection message from the communication network, activating IMSI 2 by refreshing the IMSI in the terminal; And transmitting a location registration message to a communication network in the activated IMSI 2 mode and receiving a location registration message from the communication network.

이하 본 발명이 바람직한 실시 예들을 첨부한 도면을 참조하여 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 등록정보 및 인증을 위한 정보를 포함하는 IMSI 구성도이다.1 is a block diagram of an IMSI including registration information and information for authentication according to the present invention.

국제 이동가입자 식별(International Mobile Subscriber Identity;이하 IMSI)번호인 IMSI는 가입자 식별 모듈(SIM/USIM) 카드에 내장된다. 총 15자리수로 구성되며 단말기의 국적을 식별(MCC; 3 digits)하는 코드, 이동국의 홈네트웍(Home PLMN)을 식별(MNC; 2 digits)하는 코드 및 네트웍(PLMN)내의 이동국을 식별(MSIN; 10 digits)하는 숫자이다. 본 발에 따른 IMSI에는 필수사항인 단말기 위치등록 정보를 전송하기위한 다중접속을 통한 동적 서비스를 받기위한 프로토콜 제어기술(SCM)을 포함하고, SLOT_CYCLE_INDEX가 변경될 확률이 많으므로 이 파라메터로 인하여 등록이 수행된다. 또 마지막 등록 시간(Last Registration Time)정보, 귀착한 기지국 아이디(BSC_ID) 등을 포함한다. 상기 열거한 정보는 필수적인 등록 및 인증을 위한 정보이고 그외 상황에 따른 단말기 옵션 정보도 나타낸다. IMSI, an International Mobile Subscriber Identity (IMSI) number, is embedded in a subscriber identity module (SIM / USIM) card. It consists of 15 digits in total and codes for identifying the nationality of the terminal (MCC; 3 digits), codes for identifying the home PLMN of the mobile station (MNC; 10 digits). IMSI according to the present invention includes a protocol control technology (SCM) for receiving dynamic services through multiple access for transmitting terminal location registration information, which is mandatory, and because SLOT_CYCLE_INDEX is likely to change, registration is not possible due to this parameter. Is performed. Last registration time (Last Registration Time) information, the resulting base station ID (BSC_ID) and the like. The above-listed information is required for registration and authentication, and also indicates terminal option information according to other situations.

도 2는 본 발명에 따른 IMSI 재생(Refrsh)에 의한 네트웍 위치등록을 나타낸 블럭도이다.2 is a block diagram showing network location registration by IMSI playback according to the present invention.

무선 엑세스 네트웍(Radio Access Network; RAN)으로 이동통신단말기와 접속되는 통신네트웍 A, B, C는 각각의 위치등록 단말기를 식별하기 위한 국제 이동가입자 식별(International Mobile Subscriber Identity; IMSI)번호를 홈위치등록기(HLR)에 저장하고 있다. 위치등록 메세지를 각 통신네트웍에 송출하는 이동통신단말기에는 위치등록 정보를 포함하는 IMSI 1, IMSI 2를 범용 가입자 식별 모듈(USIM)카드에 저장된다. 하나의 통신네트웍으로 위치등록 메세지를 송신하기 위해서 단말기의 IMSI 1이 활성화(Activate) 상태가 된다. 이때 IMSI 1의 위치등록 정보에의한 우선순위가 높은 통신네트웍을 선별하여 접속한다(20). 우선순위에 따라 차례로 위치등록 메세지를 수신하는 통신네트웍(A, B, C)에서 IMSI 1을 포함한 단말기의 등록 상태를 판단한다. 하나의 통신네트웍으로부터 위치등록 실패 메세지를 수신하는 단말기는 다음 우선순위인 네트웍으로 위치등록을 시도한다. IMSI 1에 의한 모든 통신네트웍(A, B, C)으로부터 단말기 위치등록이 실패한 경우 USIM 카드에 IMSI 1에 의한 통신네트웍(A, B, C)의 위치등록이 불가함을 나타내는 메세지를 수신한다(21). USIM 카드에 메세지를 저장하고 IMSI 재생(Refresh)을 수행한다. 이때 단말기 USIM 카드는 두 번째 모드인 IMSI 2가 활성화(Activate)된다. 이때 IMSI 2의 위치등록 정보에의한 우선순위가 높은 통신네트웍을 선별하여 접속한다(23). 우선순위에 따라 차례로 위치등록 메세지를 수신하는 통신네트웍(A, B, C)에서 IMSI 2를 포함한 단말기의 등록 상태를 판단한다. 적어도 하나의 통신네트웍으로부터 위치등록 메세지를 수신하여(22) USIM 카드에 기지국 아이디(BSC_ID)를 포함하여 위치등록 정보를 갱신한다. Communication networks A, B, and C, which are connected to a mobile communication terminal through a radio access network (RAN), are assigned an International Mobile Subscriber Identity (IMSI) number to identify each location registration terminal. It is stored in the register (HLR). The mobile communication terminal which transmits a location registration message to each communication network stores IMSI 1 and IMSI 2 including location registration information in a universal subscriber identity module (USIM) card. In order to send a location registration message to one communication network, IMSI 1 of the terminal is activated. At this time, the communication network with high priority based on the location registration information of IMSI 1 is selected and connected (20). The registration status of the terminal including the IMSI 1 is determined in the communication networks A, B, and C which receive the location registration message in order according to the priority. The terminal receiving the location registration failure message from one communication network attempts to register the location to the next priority network. If the terminal location registration fails from all communication networks A, B and C by IMSI 1, a message indicating that the location registration of communication networks A, B and C by IMSI 1 cannot be received in the USIM card ( 21). Save the message on the USIM card and perform IMSI Refresh. At this time, the terminal USIM card is activated (IMSI 2), the second mode. At this time, the communication network of high priority based on the location registration information of IMSI 2 is selected and connected (23). The registration status of the terminal including the IMSI 2 is determined in the communication networks A, B, and C which receive the location registration message in order according to the priority. A location registration message is received from at least one communication network (22) to update the location registration information including the base station ID (BSC_ID) in the USIM card.

도 3은 본 발명에 따른 IMSI 재생(Refresh)에 의한 네트웍 위치등록을 나타낸 흐름도이다.3 is a flowchart illustrating network location registration by IMSI Refresh according to the present invention.

S300 단계에서 이중모드 USIM 카드의 IMSI 1이 활성화된다. IMSI 1의 위치등록 정보에의한 우선순위가 높은 통신네트웍에 위치등록 메세지를 송신한다(S301). 이때, 통신네트웍에서 수신한 IMSI 1을 포함한 단말기의 등록상태를 판단한다. IMSI 1에 의한 위치등록이 실패한 경우 네트웍으로부터 위치등록 실패 메세지를 수신한다(S303). 우선순위에 의한 모든 통신네트웍으로부터 위치등록이 실패한 경우 USIM 카드에서 IMSI 재생(Refresh)을 수행한다. USIM 카드의 IMSI 2가 활성화되어(S304) 통신네트웍으로 위치등록 정보를 포함한 IMSI 2를 송신한다(S305). 적어도 하나의 통신네트웍으로부터 위치등록 메세지를 수신한다. 이때 단말기는 대기상태가 된다(S306). In step S300 IMSI 1 of the dual mode USIM card is activated. The location registration message is transmitted to the communication network of high priority based on the location registration information of IMSI 1 (S301). At this time, the registration state of the terminal including the IMSI 1 received from the communication network is determined. If location registration by IMSI 1 fails, a location registration failure message is received from the network (S303). If location registration fails from all communication networks by priority, IMSI Refresh is performed on USIM card. IMSI 2 of the USIM card is activated (S304) and transmits IMSI 2 including location registration information to the communication network (S305). Receive a location registration message from at least one communication network. At this time, the terminal is in the standby state (S306).

상술한 바와 같이 본 발명은 네트웍 위치등록시 이동통신단말기의 IMSI 재생(Refresh)방법을 제공함으로써, 2개 이상의 IMSI를 포함한 USIM에서 효율적인 네트웍 위치등록을 가능하게 한다. As described above, the present invention provides an IMSI refresh method of a mobile communication terminal when registering a network location, thereby enabling efficient network location registration in a USIM including two or more IMSIs.
