본 발명은 DBDM(Dual Band Dual Module) 단말기용 USIM(Universal Subscriber Identify Module)에 관한 것으로서, 특히 IMSI(International Mobile Subscriber Identity)뿐만 아니라 단말기 고유번호(ESN)가 저장되어 있는 DBDM 단말기용 USIM에 관한 것이다. The present invention relates to a Universal Subscriber Identify Module (USIM) for a Dual Band Dual Module (DBDM) terminal, and more particularly to a USIM for a DBDM terminal in which a terminal unique number (ESN) is stored as well as an International Mobile Subscriber Identity (IMSI). .

현재 국내 통신사업자는 2G 동기식 서비스를 하고 있으나, 점차 3G 비동기식 서비스로 옮겨 가고 있는 추세이다. Currently, domestic telcos are providing 2G synchronous services, but they are gradually moving to 3G asynchronous services.

기존의 2G 동기식 단말기로는 3G 비동기식 서비스를 이용할 수 없기 때문에 3G 서비스를 받을 수 있는 전용단말기가 있어야 하는데, 아직까지는 2G 동기식 서비스가 주류를 이루고 있어서 2G 및 3G 서비스 모두를 수용할 수 있는 겸용 단말기가 요구된다.Since existing 2G synchronous terminals cannot use 3G asynchronous services, there should be a dedicated terminal that can receive 3G services. Required.

DBDM 단말기가 바로 2G 및 3G 겸용 단말기로서, 동기식 및 비동기식 통신에서 모두 사용될 수 있다.DBDM terminals are 2G and 3G combined terminals, which can be used in both synchronous and asynchronous communications.

동기식에서는 그 기술표준에 따라 1개 단말기에 1개 신호만을 보내도록 규정하고 있다. 이를 위해 단말기 내부에 단말기 고유번호(ESN)를 저장하여 통신망에 등록하여야 한다. In the synchronous type, only one signal is sent to one terminal according to the technical standard. To this end, the terminal unique number (ESN) must be stored in the terminal and registered in the communication network.

비동기식에서는 단말기와 함께 스마트 카드(Smart Card)의 일종인 SIM(Subscriber Identity Module)이 제공된다. SIM은 개인의 이동성을 보장하는 것으로 사용자는 자신의 단말기가 아니더라도 다른 단말기에 SIM을 삽입하여 이동서비스를 받을 수 있다. SIM에는 가입자 식별코드가 저장되어 있어서 무선통신 시스템에 접속시 사용자 인증용으로 사용된다. In asynchronous mode, a terminal is provided with a subscriber identity module (SIM), which is a kind of smart card. The SIM guarantees the mobility of the individual and the user can receive the mobile service by inserting the SIM into another terminal even if it is not his terminal. The SIM stores a subscriber identification code and is used for user authentication when accessing a wireless communication system.

USIM은 SIM보다 한층 진화된 것으로서, 지금까지 가입자 식별모듈(SIM), 사용자 식별모듈(UIM) 등 이동통신 서비스 종류별로 나뉘어져 있던 식별장치를 통합한 개념이다.USIM is more advanced than SIM, and is a concept of integrating identification devices divided by mobile communication service type such as subscriber identification module (SIM) and user identification module (UIM).

USIM에는 가입자 식별코드로서 IMSI(International Mobile Subscriber Identity)가 저장되어 있어서, 비동기식 무선 통신망에 접속시 사용자 인증용으로 사용된다.USIM stores an International Mobile Subscriber Identity (IMSI) as a subscriber identification code and is used for user authentication when accessing an asynchronous wireless communication network.

또한, USIM에는 IMSI뿐만 아니라 사용자에 관한 여러 정보를 담고 있어서 단 말기를 이용한 전자상거래 및 글로벌 로밍서비스를 지원할 수 있으며, 교통카드나 전자화폐로도 사용될 수 있다. In addition, the USIM contains not only IMSI but also various information about the user, and can support electronic commerce and global roaming service using a terminal, and can also be used as a transportation card or electronic money.

비동기식 IMT―2000인 WCDMA 서비스를 계획하고 있는 국내 통신업체는 동기 및 비동기 서비스가 모두 가능한 DBDM 단말기를 개발하고 있으며 동시에 이 DBDM 단말기에 삽입되는 USIM을 개발하고 있다. Domestic carriers planning WCDMA service, asynchronous IMT-2000, are developing a DBDM terminal capable of both synchronous and asynchronous services, and at the same time, developing a USIM inserted into the DBDM terminal.

현재 DBDM 단말기는 USIM에 IMSI를 저장하여 두고, 비동기식 통신망에서는 IMSI의 일치를 확인하여 사용되고, 동기식 통신망에서는 상기한 ESN 및 IMSI가 쌍으로 일치될 때 망에 정상적으로 등록되어 사용된다. Currently, the DBDM terminal stores the IMSI in the USIM. In the asynchronous communication network, the IMSI is used to confirm the match of the IMSI.

그런데, 현재 DBDM 단말기를 설계할 때 ESN을 동기식 모뎀에 저장하고, USIM에는 IMSI만 저장하고 있다. However, when designing a DBDM terminal, the ESN is stored in the synchronous modem, and only the IMSI is stored in the USIM.

이와 같이 ESN 및 USIM을 각각 따로 저장하게 되면, 개인의 이동성이 보장되지 않는다는 문제점이 있다. 즉, 동기식 모뎀에 ESN을 저장하게 되면 USIM이 DBDM 단말기에 종속되기 때문에 다른 DBDM 단말기에 자신의 USIM을 삽입하여 동기식 통신망의 서비스를 이용할 수 없다는 문제점이 있다. As such, when the ESN and the USIM are stored separately, there is a problem that individual mobility is not guaranteed. In other words, if the ESN is stored in the synchronous modem, the USIM is dependent on the DBDM terminal, so that the service of the synchronous communication network cannot be used by inserting its USIM into another DBDM terminal.

본 발명은 상기와 같은 문제점을 해결하기 위해서 창안된 것으로서, 동기식 통신망에서도 개인의 이동성을 보장할 수 있도록 이동통신 서비스를 위한 인증에 사용되는 ESN이 저장되어 있는 DBDM 단말기용 USIM을 제공하는 것을 목적으로 한다. The present invention was devised to solve the above problems, and an object of the present invention is to provide a USIM for a DBDM terminal in which an ESN used for authentication for a mobile communication service is stored so as to guarantee individual mobility even in a synchronous communication network. do.

이를 위해, 본 발명에 의한 DBDM 단말기용 USIM은 단말기 고유번호(ESN)가 저장된 메모리와, 상기 메모리에 저장된 ESN이 이동통신 서비스를 위한 인증에 사용될 수 있도록 단말기 본체에 저장된 ESN을 불활성화시키는 ESN 불활성 수단을 포함하여 구성된다. To this end, the USIM for DBDM terminal according to the present invention is ESN deactivation means for deactivating the ESN stored in the terminal body and the ESN stored in the terminal body so that the ESN stored in the memory can be used for authentication for mobile communication services It is configured to include.

이하, 첨부된 도면을 참조하여 본 발명을 설명하면 다음과 같다. Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 적용되는 DBDM 단말기의 개략적인 구성을 나타낸다. 1 shows a schematic configuration of a DBDM terminal applied to the present invention.

도 1에 도시된 바와 같이, DBDM 단말기(1)는 CDMA 모뎀 프로세서(2) 및 WCDMA 모뎀 프로세서(3)를 포함하여 구성한다. As shown in FIG. 1, the DBDM terminal 1 comprises a CDMA modem processor 2 and a WCDMA modem processor 3. As shown in FIG.

CDMA 모뎀 프로세서(2)는 동기식 모뎀으로서 동기식 통신을 처리하는데 사용되고, WCDMA 모뎀 프로세서(3)는 비동기식 모뎀으로서 비동기식 통신을 처리하는데 사용된다. 따라서, DBDM 단말기(1)는 두 가지 통신방식이 모두 사용 가능한 겸용 단말기이다. The CDMA modem processor 2 is used to handle synchronous communications as a synchronous modem, and the WCDMA modem processor 3 is used to handle asynchronous communications as an asynchronous modem. Therefore, the DBDM terminal 1 is a combined terminal in which both communication methods can be used.

USIM(4)은 DBDM 단말기(1)에 삽입되어 사용된다. The USIM 4 is inserted into the DBDM terminal 1 and used.

USIM(4)에는 통신 서비스를 받는데 필요한 인증을 위한 데이터 및 사용자의 개인정보가 저장되어 있다. The USIM 4 stores data for authentication and personal information of a user required for receiving a communication service.

통신 서비스를 받는데 필요한 인증을 위한 데이터란 사용자 식별코드(IMSI)로서, 무선 통신망에 등록된 사용자 식별코드와 USIM(4)에 저장된 사용자 식별코드가 일치할 때 서비스를 받을 수 있다. The data for authentication required to receive the communication service is a user identification code (IMSI), and the service can be received when the user identification code registered in the wireless communication network and the user identification code stored in the USIM 4 match.

비동기식에서는 사용자 식별코드만 일치하면 서비스를 이용할 수 있으나, 동기식에서는 사용자 식별코드와 함께 단말기 고유번호(ESN)가 쌍으로 일치해야 서비스를 이용할 수 있다. In asynchronous mode, the service can be used only if the user identification code is matched. In synchronous mode, the service can be used only when the user identification code and the terminal identification number (ESN) match in pairs.

종래에는 단말기 고유번호가 CDMA 모뎀 프로세서(2)에 등록되어 있고 USIM(4)에는 IMSI만이 저장되어 있어서, USIM(4)이 DBDM 단말기(1)에 종속되어 있었다. 그러나, 본 발명에서는 ESN을 USIM(4)에도 저장함으로써 DBDM 단말기(1)에 대한 USIM(4)의 종속성을 제거한다. Conventionally, the terminal unique number is registered in the CDMA modem processor 2 and only the IMSI is stored in the USIM 4, so that the USIM 4 is subordinate to the DBDM terminal 1. However, in the present invention, the ESN is also stored in the USIM 4 to eliminate the dependency of the USIM 4 on the DBDM terminal 1.

본 발명에 의한 USIM(4)이 DBDM 단말기(1)에 삽입되면 CDMA 모뎀 프로세서(2)에 저장된 ESN이 불활성화되고 USIM(4)에 저장된 ESN 및 ISMI가 함께 읽혀져 비동기식 서비스를 위한 인증에 사용된다. When the USIM 4 according to the present invention is inserted into the DBDM terminal 1, the ESN stored in the CDMA modem processor 2 is deactivated, and the ESN and ISMI stored in the USIM 4 are read together and used for authentication for asynchronous service. .

도 2는 본 발명에 의한 USIM(4)의 개략적인 내부 구성도이다. 2 is a schematic internal configuration diagram of the USIM 4 according to the present invention.

도 2에 도시된 바와 같이, USIM(4)은 단말기 고유번호(ESN)가 저장된 메모리(10)와, 상기 메모리(10)에 저장된 ESN이 이동통신 서비스를 위한 인증에 사용될 수 있도록 DBDM 단말기(1)의 CDMA 모뎀 프로세서(2)에 저장된 ESN을 불활성화시키는 ESN 불활성화 수단(20)을 포함한다. As shown in FIG. 2, the USIM 4 includes a memory 10 in which a terminal unique number (ESN) is stored, and a DBDM terminal 1 so that the ESN stored in the memory 10 can be used for authentication for a mobile communication service. ESN deactivation means 20 for deactivating the ESN stored in the CDMA modem processor 2).

상기 메모리(10)는 USIM(4)에 예비적으로 마련된 64KB 공간 이상의 메모리로서, 단말기 고유번호(ESN)가 저장되어 있다. The memory 10 is a memory of 64 KB or more space preliminarily provided in the USIM 4, and stores a terminal unique number (ESN).

상기 ESN 불활성화 수단(20)은 DBDM 단말기(1)의 CDMA 모뎀 프로세서(2)에 저장되어 있는 ESN과 USIM(4)에 저장되어 있는 ESN의 상호 충돌을 방지하기 위해, USIM(4)이 DBDM 단말기(1)에 삽입될 때 DBDM 단말기(1)의 CDMA 모뎀 프로세서(2)에 저장된 ESN을 불활성화 시켜서 USIM(4)에 저장된 ESN만이 서비스 인증에 사용될 수 있도록 한다. The ESN deactivation means 20 uses the DBIM of the DBN terminal 1 to prevent the ESN stored in the CDMA modem processor 2 and the ESN stored in the USIM 4 from interfering with each other. When inserted into the terminal 1, the ESN stored in the CDMA modem processor 2 of the DBDM terminal 1 is inactivated so that only the ESN stored in the USIM 4 can be used for service authentication.

상기한 바와 같이, 본 발명은 USIM에 단말기 고유번호(ESN)를 저장하여 둠으로써 비동기식 통신망에서뿐만 아니라 동기식 통신망에서 개인의 이동성을 보장하는 효과가 있다. As described above, the present invention stores the terminal unique number (ESN) in the USIM, thereby ensuring the mobility of the individual in the synchronous communication network as well as in the asynchronous communication network.

즉, 사용자는 자신의 USIM을 어떤 DBDM 단말기에라도 삽입함으로써 단말기에 종속되지 않고 즉시 통신 서비스를 이용할 수 있는 효과가 있다. In other words, by inserting the USIM into any DBDM terminal, the user can use the communication service immediately without being dependent on the terminal.
