The present invention provides a quick search, access and registration of a system capable of receiving a mobile communication service by a mobile terminal (UE). Particularly, in the state of moving between multiple systems using system multi-registration information of a SIM. The present invention relates to a system search registration method of a portable terminal which detects, connects and registers with an optimal system quickly.

The mobile terminal (UE: USER EQUIPMENT) is a wireless communication with the other party anytime, anywhere and easily while moving within the registered and registered mobile communication service area, the individual directly carry, move and communicate.

The mobile terminal (UE) is provided with a mobile communication service in a service area operated by another operator out of the registered mobile communication service area by a roaming service sharing a corresponding database, and the mobile communication service A realm can be each country (COUNTRY).

The GSM (GLOBAL SYSTEM FOR MOBILE COMMUNICATION) mobile communication system operates a limited frequency resource in a TDMA (TIME DIVISION MULTIPLE ACCESS) method, so that a plurality of subscribers (SUBSCRIBER) or a mobile terminal (UE: USER) EQUIPMENT) is a digital system that occupies allocated channels at the same time and communicates on the move, and is a standard mobile communication system commonly selected in the EUROPE region.

In Europe, a GSM mobile communication system is commonly used and a roaming service is provided. Therefore, the mobile terminal UE may be moved to any country or carry a UE mobile terminal. If this is inconvenient, carry the subscriber information module (SIM: SUBSCRIBER IDENTITY MODULE), which records the subscriber's personal information including the subscriber's financial information, the mobile telephone number, the registered mobile communication system, and the operation information of the mobile terminal. When renting a mobile terminal (UE) and attaching and connecting the SIM (SIM), it is possible to immediately connect to a mobile communication system by roaming and receive a service.

The GSM mobile terminal searches for a mobile communication system that can be connected, selects a system having the best condition, and connects the last connected system to RPLMN (REGISTERED PUBLIC LAND MOBILE NETWORK), and registers a system registered with HPLMN. (HOME PUBLIC LAND MOBILE NETWORK), a system that is stored in the SIM of the mobile terminal, retrieved and connected to the system is called PLMN (PUBLIC LAND MOBILE NETWORK).
In the mobile communication system, a change in a base station or a system currently registered by a mobile terminal due to a mobile state is generally referred to as handover.

When roaming by using the mobile terminal (UE), there is a problem that it takes a relatively long time in the process of searching for and registering the optimal system that can be connected, so that the system search registration by the roaming service is improved and speeded up. There is a need for development.
