Abstract

The embodiment of the invention discloses a network selection method and a terminal, and relates to the technical field of communication. The method includes the steps that the terminal judges whether a first searched cell meets preset conditions; if the first searched cell meets the preset conditions, the terminal obtains a mobile country code (MCC) of the cell according to system information of the cell; the terminal inquires a roaming network list and determines a public land mobile network (PLMN) according to the MCC of the cell, an MCC corresponding to a subscriber identity module (SIM) card of the terminal, a mobile network code (MNC) corresponding to the SIM card and a network selection strategy; the terminal initiates a registration process according to the determined PLMN. The network selection method is suitable for a mobile terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network selection method and a terminal. Background technique [0002] With the increasing globalization of the economy, people have more and more opportunities to go abroad, and people have higher and higher requirements for mobile phones and other terminals when roaming internationally. Many users hope that one mobile phone and one SIM (Subscriber Identity Module, customer identification module) card can be used in all countries in the world. When the mobile phone is roaming internationally, in order to achieve normal communication, the operator of the SIM card used by the mobile phone needs to sign a roaming agreement with the local operator. [0003] There are at least the following problems in the prior art: when a mobile phone searches for a registration network, it generally selects the network with the best signal for registration, and the selection process need...
