The present invention uses a home service in a multinational service provider system by multi-operating IMSI information of a mobile terminal, and in particular, records and manages the temporary information of all systems operated by a multinational mobile service provider of a franchise type in a table. The present invention relates to a multi-temporary information operating apparatus and method of a portable terminal which registers a location to a home system quickly and uses a home service since the temporary information is selected and operated by a refresh command.

The mobile communication system uses a registered mobile terminal (MS: MOBILE STATION or ME: MOBILE EQUIPMENT) to form a service area formed by a corresponding base station (RAN: RADIO ACCESS NETWORK) of the system or mobile network. By freely moving inside, the mobile switching center (MSC: MOBILE SWITCHING CENTER) monitors, controls, and switches the communication path established by SWITCHING. It is a high-tech wireless communication device that moves everywhere.

The portable terminal is compact and lightweight for portability and mobility, and the utilization time is low because the time used for actual communication is small, and the low portable terminal (MS) as described above is used to increase the utilization rate and increase the practicality and convenience of real life. Various additional services, for example, TV (TV), wireless Internet, multimedia messages, cameras, infrared communication, Bluetooth communication, providing additional services, such as games, new additional services continue to be developed and added.

The mobile communication system uses a limited and limited radio frequency resource to allow a plurality of subscriber portable terminals to simultaneously occupy and move the allocated channel, and to divide and allocate the limited radio frequency resource to each channel. It is classified into various techniques by the method.

The representative method of the frequency division operation method of the mobile communication system is developed and developed mainly in Korea and the USA, and is convenient in a multinational environment centered on a code division multiple access (CDMA) method and Europe (EUROPE). There is a GSM (GLOBAL SYSTEM FOR MOBILE COMMUNICATION) method developed and developed to use it easily, but as the high-speed multimedia communication method is developed, it is developing in a manner that gathers the advantages of the two systems.

In the European region in which the GS method is operated, countries are adjacent to each other, so that the movement between countries is relatively easy, and when moving between countries, a mobile communication service provider is different.

The mobile terminal is called a registered operator system home system (HPLMN: HOME PUBLIC LAND MOBILE NETWORK), roaming (ROAMING) system that is not registered subscription, but provides a mobile communication service limited by the contract between the operators It is called (PLMN).

In addition, multinational operators have emerged as franchises that have built their own service network system in various countries due to the expansion of operators.

The GSM mobile terminal is assigned an IMSI (IMTER: INTERNATIONAL MOBILE STATION IDENTIFICATION) number corresponding to an electronic serial number (ESN) and recorded in a SIM.

When the operating power is supplied to the portable terminal, the location information is registered by registering various information registered in the SIM with the system. The system registers SIM information of the SIM with its own system. If it is, it provides a home service, and if it is confirmed that it is subscribed to another system, it provides a roaming service.

In the SIM, other necessary information is recorded and updated and managed, including the last registered system information LPLMN, the recently registered system information RPLMN, and the home system information HPLMN. The IMSI information is recorded and managed in units of ELEMENTARY FILE (EF) files.

The mobile communication system analyzes SIM information input during the location registration process of the mobile terminal, extracts IMSI information, and searches for a corresponding database, and thus is registered in its own system. ) If it is a number (IMSI) registered in its own system to provide a home service, and if it is a registered (IMSI) number registered to another system provides a roaming service.

The home service can use all the additional services provided by the mobile communication system, and the roaming service is limited to voice level communication and the like, and the communication cost is also expensive.

Accordingly, a mobile terminal registered to any one service provider system among a plurality of mobile communication service providers operated by the multinational service provider is configured to receive a home service in a system operated by the corresponding multinational service provider that is a franchise. There is a need to develop skills.

Hereinafter, a temporary information operating method of a portable terminal according to the prior art will be described with reference to the accompanying drawings.

1 is an explanatory diagram of a service area movement state of a general GSM mobile terminal, and FIG. 2 is a flowchart of a method for registering temporary information locations of a mobile terminal according to the prior art.

Referring to the attached Figure 1, for example, the first gsm mobile terminal 30 is managed and operated by the corresponding mobile communication service provider of the United Kingdom (UL: UNITED KINGDOM) (Location Information Code 234) In the service area 15 formed by the base stations 234-01 and 10, the location registration (LOCATION REGISTRATION) and the home service (HOME SERVICE) are provided using the relevant IMSI information.

The mobile terminal 30 moves to the Italy (ITALY) area due to travel, etc., and the service area of the base station 20, which is operated by the mobile communication service provider in the Italy (location information code 222) area ( SERVICE AREA (25), the mobile terminal (30 ') provides the relevant (IMSI) information to the base station (222-02) (20), the location registration (LOCATION REGISTRATION), roaming It is provided with mobile communication service of origination and reception by service (ROAMING SERVICE).

Since the GS portable terminals 30 and 30 'are registered to subscribe to the service provider mobile communication system including the base station 10 located in the UK, the service area 15 of the base station 10 is homed. In a service provider mobile communication system provided with a service (HOME SERVICE) but including a base station 20 located in Italy, roaming is registered and roaming in the service area 25 of the base station 20. Receive a service (ROAMING SERVICE).

The home service uses all the supplementary services provided by the service provider, but the roaming service is provided with a basic voice level communication service by calling and receiving, and the communication service fee is relatively expensive.

In addition, in the case of multinational mobile communication service providers, the location information code (LAC: LOCATION AREA CODE), communication area information (MCC: MOBILE COUNTRY CODE), communication network information (MNC: MOBILE NETWORK CODE), Manage service providers who construct and operate the system based on the base station unique number (CELL ID).

However, if the same service provider is operated, and the country area is different, the temporary (IMSI) information registered in each system is different, so roaming location registration before being assigned the temporary (IMSI) number registered in the country There is a problem with roaming service.

However, access to a system managed by the same service provider and settlement of communication charges using the mobile communication service in the same rate system may be separately arranged.

Therefore, even when a multinational service provider manages and accesses a mobile communication system in a different country, there is a problem in that roaming registration and roaming service should be provided.

Hereinafter, a temporary information location registration method of a portable terminal according to the prior art will be described with reference to FIG. 2.

The portable terminal 30, 30 ', when the operating power is switched from the OFF state to the ON state is applied or moved to a service area that changes the system by traveling, moving, etc., Last access system (LPLMN: LAST PLMN) that searches for and receives system information capable of wireless access in the vicinity (S10) and records and manages system information of a cell (CELL) received from the searched base station in the SIM unit of the mobile terminal. It is determined whether the information is the same (S20).

If the system information of the last access cell and the system information of the currently located cell is the same in the determination (S20), the location registration for receiving a home service is provided (S90), and the system information of the currently located cell is different from the information of the last access cell. In operation S30, it is determined whether the information is included in the connected system (RPLMN: REGISTERED PLMN) information.

If it is included in the system information that was connected in the determination (S30), the home service is registered (S90), if not included, it is determined whether it is included in the home system (HPLMN: HOME PLMN) information (S40), Register the home service (S90).

If it is not included in the home system information in the determination (S40), it is determined whether the user (USER) is included in the information of the designated system (S50), and if it is not included in the information of the system designated by the user in the determination (S50). It is determined whether the operator is included in the designated system information (S60).

If it is not included in the system information specified by the operator in the determination (S60), the roaming area (ROAMING AREA) is displayed (S70), the location registration in the system of the cell currently located to use the roaming service (S80).

Standards related to the location registration of the mobile terminal are described in more detail in 3GPP, 24.008 CORE NETWORK PROTOCOLS, STAGE 3, 31.111 USIM APPLICATION TOOLKIT (USAT) and the like.

In the prior art of the above configuration, since there is only one piece of interim (IMSI) information allocated to the mobile terminal, even if one operator manages a plurality of service networks in a franchise form, the system may be different in different countries or different in network configuration. When connected, there is a problem in that a roaming system is divided and a roaming service is used.

In addition, a system managed by the same operator as described above may be registered in the operator-specified system list, but the priority is lower than that of the user-specified system list, so that the time required to register is longer, and other networks in the process of registering are registered. There is a problem such as a possibility to connect to (NETWORK).

In addition, if it is determined that an inappropriate mobile terminal (INVALID ME / MS) from a specific network (NETWORK), no further attempts to connect to another network (NETWORK), emergency communication (EMERGENCY, such as 119, 112, etc.) in the current cell system There is a problem that the limited service (LIMITED SERVICE) state is not provided any more mobile communication service except for CALL).

According to the present invention, if a service provider registering a mobile terminal is a multinational operator based on a franchise, it records and manages temporary information registered in a system of all the countries in which it operates, as a table, and whether the information of a cell currently located by STI is included in the table.
