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

[0023] 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.

[0024] The method of the present invention is especially applied to a single-mode mobile terminal working on a CDMA network, or a multi-mode mobile terminal whose working network includes a CDMA 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:

[0025] S1. The mobile terminal searches for the strongest pilot message, and obtains a system identification code (SID). Specifically, this step further includes:

[0026] S1.1 The mobile terminal acquires available frequency points and searches for the strongest pilot message, where the strongest pilot message is the pilot message with the highest power received at the location of the mobile terminal. When the mobile...

Abstract

The invention discloses a geographical position identification method of a mobile terminal. The geographical position identification method of the mobile terminal comprises the steps of: S1, searching the strongest pilot frequency message by the mobile terminal, and obtaining a system identification code, and S2, identifying the geographical position at which the mobile terminal is according to the system identification code. According to the method disclosed by the invention, active and rapid geographical position identification of the mobile terminal is achieved, and a time zone is synchronized, thereby achieving rapid registering of a network according to related network information corresponding to the geographical position.

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...
