The present invention relates to a mobile multimedia network search registration for a roaming service of a mobile multimedia terminal, and more particularly, it relates to a method and apparatus for manually selecting and registering one of mobile multimedia networks in a list, And more particularly, to a network connecting apparatus and method for a wireless terminal that uses a roaming service quickly and easily.

UNIVERSAL MOBILE TELECOMMUNICATION SYSTEM (UMTS) system uses the GSM (Global System for Mobile Communication) method widely used in Europe and other areas, and can transmit high-speed data over 2 Mbps. (3GPP) mobile communication system capable of accessing the Internet while moving, in a place where the same method is used anywhere in the world.

The GSM scheme used in Europe is a type of time division multiple access (TDMA) scheme that uses a 900 MHz radio frequency band and a 1.8 GHz radio frequency band, It uses GSM1800 or DIGITAL CORDLESS SYSTEM (DCS) method to expand radio frequency resources, and uses GSM and DCS together as a PCS (PERSONAL COMMUNICATION SYSTEM) concept.

A third generation mobile communication system capable of multimedia communication in the European region is called a universal mobile telecommunication system (UMTS), and data is transmitted at a high speed of 2 Mbps or higher using a radio frequency signal of 2.1 GHz band, (ASYNCHRONOUS) system using WCDMA and similar concept to IMT-2000, the next generation mobile communication system in Korea.

That is, a conventional mobile communication system in Europe uses a GSM system including a DCS, which is a kind of time division multiple access (TDMA) system, and a next generation mobile communication system capable of multimedia communication, (UMTS) scheme, which is a division multiple access (CDMA) scheme.

The user equipment (UMTS) mobile terminal moves freely in a service area formed by a radio access network (RAN) of a mobile communication system registered in a local area (LOCATION REGISTERED) It immediately communicates with the desired party anytime and anywhere via the communication path established by the monitoring and control of the MSC (Mobility Switching Center) and the switching (SWITCHING).

The service area is formed by a base station (RAN) including a base station controller (BSC). A signal close to a base station (RAN) is good in the service area, In the outskirts of the service area or in areas with many obstacles, the communication quality is poor because a lot of noise is mixed.

In Europe where the above-mentioned GMS method and the UMTS method are used, a plurality of countries are adjacent to each other. In addition, since there are many service providers in one country, when the communication quality of the currently connected communication network is low, It provides a ROAMING service using mobile communication services of adjacent communication networks.

As described above, the UMTS mobile terminal has a function of searching for and connecting to a UMTS network of another adjacent business entity, and there are an automatic method and a manual method for the network search and connection.

A procedure for searching a network and creating a list when the UMTS network is searched and accessed manually; a procedure for selecting and accessing and registering a desired network from the searched NETWORK list (LIST) .

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

Accordingly, there is a need to develop a technique for quickly and easily accessing a neighboring multimedia network having a good communication quality by simplifying the manual network search and connection procedure of the mobile multimedia terminal as described above.

Hereinafter, a passive network connection method of a conventional mobile multimedia terminal will be described with reference to the accompanying drawings.

FIG. 1 is a functional block diagram of a general mobile communication system, FIG. 2 is a flowchart of a conventional method of connecting a passive network of a mobile multimedia terminal, and FIG. FIG. 2 is a flowchart of a mobile communication network connection procedure of a mobile terminal; FIG.

1, a mobile terminal (UE) 10 wirelessly connects within a service area formed by a first base station (RAN) 20, and a first mobile switching center The mobile communication service provided by the first mobile switching center 30 is provided.

When the mobile terminal 10 is located in the outer area of the service area formed by the first base station 20, the mobile communication service quality is degraded.

When the outer service area of the first base station 20 where the portable terminal 10 is located is included in the service area of the Nth base station 25 and the signal quality of the Nth base station 25 is good, The mobile terminal 10 is connected to the Nth base station 25 and registers its location with the Nth mobile switching center 35 so that it continues to receive mobile communication services by ROAMING.

When the mobile terminal 10 accesses and registers an Nth network by the Nth base station 25 and the Nth mobile switching center 35, If it is found in the above, the Nth base station should be manually selected and a connection request is made, and the location should be registered in the connected state according to the request.
The manual search of the network directly selects a network by a user. Generally, the manually searched network is a network that has frequently communicated, and is a network with a high probability of receiving a smooth communication service.

As described above, there is a problem in that the neighboring networks are searched, connected, and registered to take a minimum of about 5 seconds to a maximum of about 40 seconds, depending on the frequency environment.

Also, even when connecting to and registering with another network using a network search list (LIST) created in the network search, it takes the same time every time, and until the registration is completed, There is a problem that the communication service can not be provided.

Hereinafter, a conventional passive network access method for a mobile multimedia terminal will be described with reference to FIG.

If the user wishes to access another UMTS network manually using the mobile terminal 10 in step S10, the mobile terminal 10 searches all the UMTS networks for receiving a signal in the vicinity thereof, (S20).

The time required for searching and listing the UMTS network in which the neighboring signals are received in the step S20 is different depending on the surrounding radio wave environment, (U8110 basis), the above-mentioned 40 seconds or longer is not allowed, and the mobile terminal UE is in a state in which it can not perform other functions until the search is completed.

The list (LIST) completed and searched as described above is output through the corresponding display unit of the mobile terminal (UE), and is displayed, so that it can be confirmed.

(S30), and a connection request to the selected network is transmitted to the corresponding base station (S40) by manually searching for a list displayed as above, manually selecting a preferred or required UMTS network, (S40), the location of the mobile terminal (UE) is registered with the mobile switching center (MSC) of the connected network to receive the roaming mobile communication service (S50).

Even in the case of the time required for wireless connection and registration to the selected network as described above, a time of at least about 5 seconds to a maximum of about 40 seconds is required although there is a difference depending on the surrounding radio wave environment, It is recognized that the mobile communication service by roaming can be provided because the registration completion message of the mobile switching center (MSC) is received and displayed when the mobile communication terminal is registered without being allowed any more time.

When the quality of service of the mobile network registered by manual search and selection is low as described above, it is possible to access another mobile network selected manually from the existing network list. In such a case, It takes about 40 seconds.

Hereinafter, with reference to FIG. 3, a flow of a conventional mobile communication method of a mobile communication network will be described.

FIG. 3 is a flow chart illustrating a signal processing for manually connecting to a UMTS network in a mobile terminal. When a mobile network manual search request signal is applied to a control unit through an input / output unit integrally provided in the mobile terminal (ST10), the control unit controls the radio unit to search for a UMTS network in which a signal is received from a neighbor, and creates a list of the found MMS network (ST20) (ST30).

(ST40), the input / output unit applies a request signal for manually connecting to the manually selected multimedia network to the control unit (ST50) .

The control unit receiving the manual connection request controls the radio unit, establishes a radio connection with the base station of the corresponding multimedia network, and requests location registration. Therefore, the control unit informs the mobile switching center (MSC) of the corresponding multimedia network The location is registered (ST60).

When the LOCATION REGISTRATION is completed, the mobile switching center (MSC) notifies the mobile terminal UE of the completion of location registration through the base station (RAN), and the radio unit notified of the location registration is applied to the control unit. The location registration success message is output through the display unit included in the input / output unit, so that the user recognizes that the location registration is completed in the UMTS network that is manually requested to connect (ST70).

However, since it takes about 5 seconds to 40 seconds for the network search and takes about 5 seconds to 40 seconds for the network connection registration, There is a problem that it takes time from about 10 seconds to about 80 seconds at maximum.

Therefore, with the above-described configuration, there is a problem that the conventional UMTS NETWORK connection is complicated and unnecessarily time-consuming until registration is completed.

The present invention preliminarily records and stores a list of the UMTS network to be manually connected, searches for the list, and requests a manual access to the selected UMTS network, thereby reducing the processing procedure and time, The present invention provides a network connecting apparatus and method for a portable terminal.

According to an aspect of the present invention, there is provided a mobile communication system including a search registration unit for searching for and connecting to a wireless base station network wirelessly received at a level connectable by a control signal, A control unit for controlling the search registration unit to search for and record a list of a wireless base station network wirelessly received at a connectable level, and to monitor a location registration by accessing a selected network; A list unit for recording and outputting a list of a mobile station base station network inputted by a user under the control of the control unit; And a keyboard unit connected to the control unit, for inputting a connection request signal of the selected MMS base station network and a control command for operation.
