Abstract

The invention provides a method and device for automatically selecting a network for a mobile terminal, which are used for network selection switching of the mobile terminal between a first network and a second network. The mobile terminal resides in the first network; and the method comprises the following steps of: A, acquiring a locus function for operation of the mobile terminal according to position information of the mobile terminal; B, calculating a network selection switching function of the mobile terminal according to the locus function for the operation of the mobile terminal; C, establishing a network switching region of the mobile terminal according to the network selection switching function and regions covered by the first network and the second network; and D, performing network selection switching in a corresponding network switching mode according to the network switching region where the mobile terminal is positioned and/or the signal intensity of the second network. The method and device for automatically selecting the network for the mobile terminal can switch the mobile terminal rapidly to a home network, and improves the network aware effect of a user.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for automatically selecting a network by a mobile terminal. Background technique [0002] In the prior art, the mobile terminal can switch from the currently resident visiting PLMN (VPLMN) to the home PLMN (HPLMN) in the following two ways: [0003] Method 1. When the mobile terminal switches from the currently resident visiting PLMN (VPLMN) to the home PLMN (HPLMN), it needs to manually execute a search command to check whether there is an HPLMN in the area where the mobile terminal is currently located. If HPLMN is present, you can manually switch back to HPLMN. Since the mobile terminal cannot accurately and automatically discover whether there is an HPLMN in the current coverage area, when the user is talking, even if the current HPLMN network signal coverage is good, it cannot switch back to the HPLMN from the VPLMN in time, resulting in t...
