Abstract

The invention provides a network reselection method and a mobile terminal. The method comprises the steps of detecting signal strength under a network resided by a mobile terminal; if the signal strength is smaller than a preset signal strength threshold, searching frequency points supporting target networks from an LTE (Long Term Evolution) frequency point information list; obtaining the lowest access threshold of the frequency points supporting the target network and carrying out resection measurement on the frequency points supporting the target networks; determining one frequency point from the frequency points supporting the target networks as a target frequency point according to the lowest access threshold of the frequency points supporting the target networks and a resection measurement result; and switching the network resided by the mobile terminal to the network of the target frequency point. According to the network reselection method provided by the embodiment of the invention, when the signal strength of the mobile terminal is weak, the network can be switched to a narrowband cellular network with relatively high coverage capability, so the mobile terminal can carry out normal communication, and the communication capability of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network reselection method and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals such as mobile phones and tablet computers have become indispensable tools in people's daily life. People have higher and higher requirements on mobile terminals, especially the communication capabilities of mobile terminals. However, when a user brings a mobile terminal into a place with a poor network signal, such as an underground garage or a stairwell in a building, the communication signal of the mobile terminal will be weakened or even in a state of no service, resulting in a decrease in the communication capability of the mobile terminal. affect user experience. [0003] When a current mobile terminal enters a place with weak signal strength, it generally performs network reselection to switch the current network to a...
