Description

How to determine network system using JPPS {NETWORK SYSTEM DECISION METHOD USING GLOBAL POSITIONING SYSTEM}

The present invention relates to a mobile terminal, and more particularly, to a network system determination method using GPS in a multi-mode terminal.

The current wireless telecommunications business has entered the 3rd generation telecommunications era, which provides a more reliable and flexible communication system than the previous generation.

In other words, in the first generation analog communication system, only voice calls were serviced. In the second generation digital communication system, fax and data services were added to the first generation voice calls. In the third generation mobile communication system, high-speed data services and new services were added. Video (TV), audio service (MUSIC) and Internet access are now available.

The third generation mobile communication system is largely divided into North America's synchronous CDMA2000 and Europe's asynchronous UMTS, and the second generation mobile communication system is also divided into North America's CDMA and Europe's GSM.

However, in general, communication systems already installed in one region or country cannot be replaced with new communication systems as soon as possible due to cost problems and the time required to secure and install equipment.

Accordingly, the second generation mobile communication system and the third generation mobile communication system may coexist in the same region or country for a certain period of time when users do not feel uncomfortable or want a low price communication service.

Therefore, in the third generation mobile communication system, development of a multi-mode terminal supporting a global roaming network system is required.

However, conventionally, in an environment in which a second generation and a third generation mobile communication system coexist,

The user should be able to efficiently access the network system according to the area where the user is located or the characteristics of the desired service.

Accordingly, the present invention provides a multi-mode terminal with multi-mode support for overcoming local boundaries and limitations of usage in order to improve the conventional problems, so as to support fast system acquisition and a user-friendly environment using a GPS positioning system. An object of the present invention is to provide a method for determining a network system using the invention GPS.

In order to achieve the above object, the present invention provides a network connection method of a mobile terminal equipped with a CDMA, WCDMA, and GSM method, comprising: setting a multi-mode automatic search function and receiving GPS location information on a current location; Determining a communication mode available at the received current location, setting a portable terminal in the mode determined above, and acquiring system information; And after setting the portable terminal in the basic mode, obtaining the system information.

The operation of the present invention is performed when the mobile terminal is moved from the power off state to the CDMA or GSM / WCDMA region and is disconnected from the network system while being powered on or moved from the power on state to the CDMA or GSM / WCDMA region. It features.

Therefore, in the case of a mobile terminal operating in multi-mode (CDMA, GSM, WCDMA), the present invention uses a GPS at the first power-on or system loss to determine the current location, and then selects one of the communication modes. It determines whether to operate and operates in the corresponding communication mode to provide a smooth communication service to the user.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of a system for determining a network system in an embodiment of the present invention, as shown here, a mobile terminal (hereinafter referred to as a mobile phone) 110, a base station 121, 122, a GPS satellite ( 130) including.

The mobile phone 110 is equipped with location information of the boundary of each region and information on the communication mode that can be provided in the region.

That is, the mobile phone 110 requires the following conditions.

1. The mobile phone 110 mounts location information for each country or region and communication mode information according to the location information in an internal memory. At this time, the location information and communication mode information can be input by the manufacturer or distributor and updated periodically.

2. The mobile phone 110 is configured to receive the current location information from the GPS satellite 130 or to receive the location measurement information of the external GPS receiver by using the built-in GPS receiver.

Accordingly, the mobile phone 110 checks the current location by comparing the GPS location information and the location information mounted in the internal memory, determines the communication mode available at the current location, and then communicates with the base station 121 or 122 to determine the corresponding network system information. Acquire and obtain a communication connection information by reflecting the obtained network system information.

3. The mobile phone 110 is configured to allow the user to arbitrarily select the communication mode recognition of the current location, obtain network system information on the recognized communication mode, and the corresponding operation.

4. The mobile phone 110 is configured to operate in a preset default mode when communication mode recognition or network system information acquisition fails in the multi-mode.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

First, the mobile phone 110 is moved to the CDMA or GSM / WCDMA region in the power-off state, the GPS satellite 130 when the connection to the network system is disconnected while moving to the CDMA or GSM / WCDMA region in the power-on state Receive location information from the device and check the supportable communication modes according to the location information in the internal memory.

Accordingly, the mobile phone 110 obtains network system information from the base station 121 or 122 after setting to the corresponding communication mode so as to be in a communicable state.

That is, in the embodiment of the present invention, the mobile phone 110 obtains network system information by performing the same operation as that of FIG. 2, which will be described below.

First, the mobile phone 110 checks whether the multi-mode automatic search is set.

At this time, when the mobile phone 110 moves from the CDMA region to the GSM / WCDMA region or moves from the GSM / WCDMA region to the CDMA region while recognizing that the multi-mode auto discovery function is set, or is powered on in the power-off state Check if the network system information could not be obtained while moving in the on state.

At this time, if it is determined that the network system information is not obtained while the power is turned on after the area movement in the power-off state or the area is moved in the power-on state, the mobile phone 110 receives the current location information from the GPS satellite 130.

Accordingly, the mobile phone 110 compares the GPS location information with the location information stored in the internal memory, checks the available communication mode according to the current location, sets the checked communication mode, and sets the identified communication mode with the base station 121 or 122. Communicate and obtain network system information to enable communication.

If the multi-mode search function is not set, the GPS location information is not received, or the communication mode at the current location is not confirmed, the mobile phone 110 sets the base mode 121 or 122 to a preset default mode. And communicate with the network system information.

As described in detail above, the present invention automatically determines a communication mode at a corresponding location when network system information is not obtained in a multi-mode (CDMA, WCDMA, GSM) communication environment, and based on the communication mode. By obtaining the information to be in a communicable state, a smooth communication service can be provided to the user, thereby improving user convenience and satisfying the user's satisfaction.
