CN103298075A - Fast network selection method of dual-mode terminal - Google Patents

Abstract

The invention provides a fast network selection method of a dual-mode terminal and relates to the technical field of mobile communication. The fast network selection method includes: S1, powering up and starting up the dual-mode terminal, and selecting located geographical location of the present starting-up by a user; S2, searching network information and determining the geographical location by a background of the dual-mode terminal synchronously with the step S1; S3, if the user selects the geographical location, stopping searching of the background of the dual-mode terminal and switching to a matched roaming mode to select a network according to an international roaming mode corresponding to the geographical location selected by the user in the step S1; and if the dual-mode terminal determines the located geographical location of the present starting-up according to the network information before the geographical location selection of the user, canceling the user selection, and thereby the dual-mode terminal enters a normal working mode. By the mode of selecting the geographical location by the user and automatically searching the geographical location by the dual-mode terminal concurrently, the located geographical location of the dual-mode terminal can be fast determined when the dual-mode terminal is started up, so that determination of a required terminal mode can be accelerated, and fast network selection is realized.

Description

The method of the quick network selection of dual-mode terminal

Technical field

The present invention relates to the mobile communication technology field, be specifically related to the method for the quick network selection of a kind of dual-mode terminal.

Background technology

Present CDMA/GSM/UMTS dual-mode terminal (comprising dual-mode dual-standby and double-mode single-standby terminal) is when carrying out international roaming, need at first judge its geographic location, thereby according to the demand of international roaming service, determine that it still is the GSM/UMTS pattern that terminal is finally used the CDMA pattern.Owing to when start, can not determine the geographical position at terminal place fast, terminal can only start the pattern that terminal is supported successively according to certain particular order, for example according to GSM/UMTS pattern after the first CDMA pattern, in each pattern, determine the geographical position by the information of searching for relevant operator.

The deficiency of this method is owing to will rely on the operator's informaiton of network side to determine the geographical position, which kind of no matter from pattern search, all can cause needing the long period to determine no network in the area of not having this mode of priority network, switch to another pattern again and search net, can determine terminal seat reason position, total meeting consuming time is long.Therefore, at above deficiency, the invention provides the method for the quick network selection of a kind of dual-mode terminal.

Summary of the invention

(1) technical problem of Xie Jueing

At the deficiencies in the prior art, the invention provides the method for the quick network selection of a kind of dual-mode terminal, the present invention selects geographical position and dual-mode terminal to search for the parallel mode in geographical position automatically by the user, when start, can determine the dual-mode terminal geographic location fast, thereby accelerate to determine required terminal pattern, improved the efficient of network selection.

(2) technical scheme

For realizing above purpose, the present invention is achieved by the following technical programs:

The method of the quick network selection of a kind of dual-mode terminal comprises following steps:

S1, dual-mode terminal power up startup, and the user selects this start geographic location;

S2, synchronous with step S1, dual-mode terminal backstage search network information is determined the geographical position;

S3, if the user has at first selected the geographical position, the international roaming pattern of the geographical position correspondence of selecting according to user among the step S1, the search of dual-mode terminal backstage stops, the roam mode that switches to coupling is carried out network selection; If before the user selects the geographical position, dual-mode terminal has been determined this start geographic location according to the network information, and the cancellation user selects, and dual-mode terminal enters normal mode of operation.

Preferably, the user among the step S1 selects the geographical position at this start place by the geographical position choice menus that ejects.

Preferably, dual-mode terminal in backstage search network information mode is among the step S2: the flow process of search second pattern is sought the network information after search first pattern earlier.

Preferably, described first pattern is the CDMA pattern, and second pattern is the GSM/UMTS pattern.

Preferably, the international roaming pattern of the described geographical position correspondence among the step S3 is set at three classes: CDMA mode region, CDMA mode prioritization zone and GSM/UMTS mode prioritization zone.

(3) beneficial effect

The invention provides the method for the quick network selection of a kind of dual-mode terminal, the present invention selects geographical position and dual-mode terminal to search for the parallel mode in geographical position automatically by the user, when start, can determine the dual-mode terminal geographic location fast, thereby accelerate to determine required terminal pattern, realize quick network selection.

Fig. 2, be that the user selects start geographic location schematic diagram by the geographical position choice menus that ejects.

Embodiment

Regard to the method for the quick network selection of a kind of dual-mode terminal proposed by the invention down, by reference to the accompanying drawings 1,2 and embodiment describe in detail.

CDMA/GSM/UMTS dual-mode terminal (comprising dual-mode dual-standby and double-mode single-standby terminal) can have been realized quick network selection by the method for the quick network selection of dual-mode terminal in each start process when international roaming at present.

The method of the quick network selection of dual-mode terminal comprises following steps:

At first, dual-mode terminal powers up startup, and the user selects this start geographic location by the geographical position choice menus that ejects; Dual-mode terminal is determined the geographical position in backstage search network information.

Dual-mode terminal in backstage search network information mode is: the flow process of search second pattern is sought the network information after search first pattern earlier;

Described first pattern is the CDMA pattern, and second pattern is the GSM/UMTS pattern; Also can be, first pattern be the GSM/UMTS pattern, and second pattern is the CDMA pattern; How the set basis actual conditions are selected.

Secondly, if the user has at first selected the geographical position, the international roaming pattern of the geographical position correspondence of selecting according to the user, the search of dual-mode terminal backstage stops, and the roam mode that switches to coupling is carried out network selection; If before the user selects the geographical position, dual-mode terminal has been determined the dual-mode terminal geographical position according to the network information, and the cancellation user selects, and dual-mode terminal enters normal mode of operation.

The international roaming pattern of described geographical position correspondence is set at three classes: the international roaming pattern of described geographical position correspondence is set at three classes: CDMA mode region, CDMA mode prioritization zone and GSM/UMTS mode prioritization zone, as shown in Figure 2, the corresponding CDMA mode region in China's Mainland and Macao, corresponding CDMA mode prioritization zone, ground such as the U.S., Canada, Japan, Korea S, Taiwan, other is as corresponding GSM/UMTS mode prioritization zones such as Europe.

Above execution mode only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
