Network searching method, device and terminal

Abstract

The embodiment of the invention provides a network searching method, device and terminal. The network searching method comprises the following steps: acquiring wireless spectrum information of the environment located by a mobile terminal, and extracting an effective frequency point from the wireless spectrum information; detecting whether the effective frequency point is the target frequency pointof the network searching of the terminal; if the effective frequency point is the target frequency point of the network searching of the terminal, performing network searching according to the targetfrequency point and a network system corresponding to the target frequency point. Before interacting information with a base station, the effective frequency point in the environment is firstly searched, and the target frequency point therein is determined, and finally, the network searching is performed according to the target frequency point and the network system corresponding to the target frequency point, the ineffective interaction time between the mobile terminal and the base station can be greatly reduced, thereby shortening the network searching duration and improving the network searching efficiency.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, device and terminal for searching a network. Background technique [0002] In wireless communication, a mobile terminal needs to search for a wireless network first, find a suitable network for registration, and successfully access the network before enjoying the network service provided by the operator. When the mobile terminal is restarted or the geographical location is changed, the network may be disconnected. It is necessary to search the network again and establish a connection to ensure normal communication and data transmission. [0003] When the mobile terminal searches the network again, it will first perform the system scan operation, that is, scan the multiple historical frequency band information saved in the last successful network search, and initiate registration to the base station in turn according to the historical frequency ban...
