Problems solved by technology

In this way, it is undoubtedly a waste of time to successfully register to a new network and use its services
In addition, there may be a time difference between the new network coverage area where the mobile terminal arrives and the previous network coverage area, and there is currently no active time zone update mechanism for the mobile terminal

Embodiment Construction

[0020] The method for identifying the geographic location of a mobile terminal proposed by the present invention is described in detail in conjunction with the accompanying drawings as follows.

[0021] The method of the present invention is especially applied to a single-mode mobile terminal working on a GSM network, or a multi-mode mobile terminal whose working network includes a GSM network. Such as figure 1 As shown, a method for identifying the geographic location of a mobile terminal according to an embodiment of the present invention includes steps:

[0022] S1. The mobile terminal receives and reads the broadcast channel message, and obtains the location area identification code.

[0023] When the mobile terminal leaves from the local area or country and arrives in another area or country, if it is in the power-off state, it will receive and read the GSM broadcast channel (BCH) message during the power-on process; if it is in the power-on state, it will be lost first ...

Abstract

The invention discloses a method for identifying geographic locations of mobile terminals. The method includes that firstly, the mobile terminals receive and read broadcast channel information and acquire location area identification codes; and secondly, the geographic locations of the mobile terminals can be identified according to the location area identification codes. The mobile terminals can actively quickly identify geographic locations thereof and synchronize time zones, and accordingly, quick network registration of the mobile terminals can be realized according to relevant network information corresponding to the geographic locations.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for identifying the geographic location of a mobile terminal. Background technique [0002] The mobile terminal can continue to use in another region or country after leaving the local region or country. This process is called roaming. Roaming can only be carried out between domestic cities with compatible network standards and already connected to the Internet or between regions or countries that have signed a bilateral roaming agreement. After the mobile terminal re-registers to the contracted network in the region or country, it can use the network operator service provided. [0003] In the prior art, after the mobile terminal arrives in another region or country, it will try to register in all the networks it can access, because there may be unsubscribed conditions in all the networks it can access, that is, registration unsuccessful case. In this way...
