The present invention relates to the registration of the UTM network search for roaming services of the UTM mobile terminal, and in particular, by manually selecting one of the listed UTM network and access registration, the procedure and the time required The present invention relates to a passive network access device and a method of a mobile terminal using a roaming service quickly and simply.

The UMTS (Universal Mobile Telecommunication System) system uses the Global System for Mobile Communication (GSM) method, which is widely used in other regions, especially in Europe, and enables high-speed data transmission of 2 Mbps or more. The third generation (3GPP) mobile communication system capable of connecting to the Internet while moving while using the same method anywhere in the world.

The GSM method used in Europe is a kind of time division multiple access (TDMA) method, which uses a 900 MHz radio frequency band and a 1.8 GHz radio frequency band, and uses the 1.8 GHz band. It is used to expand radio frequency resources, also known as GSM1800 or DIGITAL CORDLESS SYSTEM (DCS), and combines the GSM and DCS to operate under the concept of PCS (PERSONAL COMMUNICATION SYSTEM).

The third generation mobile communication system capable of multimedia communication in the European region is called UMTS (Universal Mobile Telecommunication System), and transmits data at a high speed of 2 Mbps or more using a radio frequency signal of 2.1 GHz band and a broadband code. It is an asynchronous (ASYNCHRONOUS) method that uses WCDMA, and is similar to IMT-2000, the next generation mobile communication system in Korea.

That is, the existing mobile communication system in Europe uses the GSM system including the DSC which is a type of time division multiple access (TDMA) system, and the next generation mobile communication system capable of multimedia communication is a code. The UMTS method, which is a division multiple access (CDMA) method, is used.

The UMTS mobile terminal (UE: USER EQUIPMENT) moves freely in a service area formed by a corresponding base station (RAN: RADIO ACCESS NETWORK) of a mobile communication system registered (LOCATION REGISTERED). Through a communication path established by monitoring, controlling, and switching of a switching center (MSC: MOBILE SWITCHING CENTER), it instantly communicates with a desired party anytime, anywhere.

The service area is formed by a base station (RAN) including a base station controller (BSC), and within the service area, a signal sensitivity is good at a place close to the base station (RAN), and a signal sensitivity is bad at a far place. In the outer area of the service area or the area with many obstacles, noise is mixed a lot, so communication quality is poor.

In the European region using the GS and UTM methods, many countries are adjacent to each other, and since there are many service providers in one country, if the communication quality of the currently connected communication network is low, access to other adjacent communication networks. The registration provides a roaming service using a mobile communication service of an adjacent communication network.

As described above, the UMTS mobile terminal is provided with a function of searching for and connecting to a neighboring operator's NETWORK. The network searching and accessing includes an automatic method and a manual method.

In the case of searching and accessing a UMTS network by the manual method, a procedure of searching for a network and creating a list, and a procedure of selecting and accessing and registering a desired network from the searched network list. There is.

The manual procedure of searching and accessing the UMTS network varies depending on the surrounding environment, but it takes about 5 seconds up to 40 seconds.

Therefore, there is a need to develop a technology for quickly and simply connecting to a neighboring UTM network having good communication quality by simplifying the manual network searching and access procedure of the UTM mobile terminal as described above.

Hereinafter, a passive network connection method of a UTM mobile terminal according to the prior art will be described with reference to the accompanying drawings.
