Abstract

The embodiment of the invention discloses a network search method and apparatus. The method comprises the following steps: when a terminal device is started up or is in a no-service state, obtaining a first mobile country code MCC in a network identifier in a currently searched public land mobile network PLMN; obtaining the network identifier of the PLMN of a first country corresponding to the first MCC from a first preset list according to the first MCC, wherein the first preset list comprises the network identifiers of PLMNs of a plurality of countries; and updating the obtained network identifier of the PLMN of the first country to an equivalent public land mobile network EPLMN list and / or an equivalent local public land mobile network EHPLMN list of the terminal device, and performing network search according to the updated EPLMN list and / or the EHPLMN list. By adoption of the network search method and apparatus disclosed by the invention, the problem of relatively low network search efficiency of the terminal device in an equivalent network search caused by inaccurate network equivalency or incomprehensive network equivalency, and the user communication experience is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for searching a network. Background technique [0002] Public Land Mobile Network (PLMN, Public Land Mobile Network) is a network established and operated by the government or its approved operators for the purpose of providing land mobile communication services for the public. This network is usually interconnected with the public switched telephone network to form an entire regional or national scale communication network. The network identifier of the PLMN is usually a series of digital codes, for example, the network identifier of the PLMN of China Mobile is 46000, the network identifier of the PLMN of China Unicom is 46001, and so on. [0003] With the improvement of people's living standards, more and more users carry terminal devices (such as mobile phones) abroad for travel or business trips. When users perform roaming communicati...
