Abstract

The embodiment of the present application provides a data updating method and a device. A terminal obtains an equivalent public land mobile network (EPLMN) information from a server. The EPLMN information includes at least one PLMN information, and the EPLMN information can be updated at the server side; The terminal loads the EPLMN information, and the loaded EPLMN information is used for matching the target PLMN obtained by searching a network by using the PLMN information in the EPLMN information in the process of registering the terminal with a network.

Description

technical field [0001] The embodiments of the present application relate to the technical field of mobile communications, and in particular to a data update method and device, and a terminal device. 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. PLMN is identified by Mobile Network Code (MNC, Mobile Network Code) and Mobile Country Code (MCC, Mobile Country Code). , Universal Subscriber Identity Module) corresponding to the PLMN in the International Mobile Subscriber Identification Number (IMSI, International Mobile Subscriber Identification Number), for a certain user, there is only one PLMN to which it belongs, that is, HPLMN. [0003] When the terminal roams to other countries, it can specify some equivalent PLMNs (EPLMN, Equivalent PLMN). Because the EPLMN of some do...
