Problems solved by technology

[0004] (1) There is no network coverage in the area where the device is located, such as: some mountainous areas without network coverage, etc.;
[0005] (2) Although there is network coverage in the area where the device is located, the signal is weak and the user cannot maintain a normal communication state;
[0007] (4) There is a problem on the network side, such as: the base station fails, etc.
This is due to the unstable signal in mountainous areas and the power consumption caused by repeated network scans by the device

Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] In the mobile communication network, due to its mobility, the terminal may continuously enter or leave areas in different network coverage conditions, such as no network coverage area, weak network signal area, and strong network coverage area. If the network cannot be searched, or the network is found to be lost after searching the network, it will search the network repeatedly in order to obtain the link with the network in time and restore the normal communication state. The present invention is realized in the above-mentioned mobile communication network environment.

Abstract

The invention discloses a terminal and a network searching method thereof, wherein the method comprises the following steps that: the terminal uses a positioning system to obtain a self position, acquires network coverage information corresponding to the obtained position, and uses the network coverage information to carry out network searching. The invention reduces unnecessary power consumption, and prolongs the service life and the standby time of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal and a network search method thereof. Background technique [0002] The terminal communication device cannot search the network after starting, or finds that the network is lost after searching the network. In this way, it will search the network repeatedly in order to obtain the link with the network in time and restore the normal communication state. [0003] The phenomenon that the terminal communication device cannot search for the network, or the network is lost after searching for the network, can be divided into the following situations: [0004] (1) There is no network coverage in the area where the device is located, such as: some mountainous areas without network coverage, etc.; [0005] (2) Although there is network coverage in the area where the device is located, the signal is weak and the user cannot maintain a normal communication state; [0006] (3) A...
