Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] At present, when the resident network of the terminal equipment is the VPLMN, the periodic search principle defined in the 3GPP specification can be used to implement HPLMN reselection. However, when the terminal device has returned to the HPLMN coverage area from the VPLMN, if the reselection timer has not expired or the terminal device is not in the Idle state, then the terminal device cannot perform HPLMN search and reselection operations at this time. Th...

Abstract

Disclosed are an HPLMN reselection method and a terminal device, which relate to the field of communications and solve the problem that a terminal device cannot return to an HPLMN in time due to the fact that a reselection timer does not time out or the terminal device is not in an idle state where the terminal device has returned from a VPLMN to a coverage region of the HPLMN. The scheme involves: a resident network of a first terminal device being a VPLMN; the first terminal device receiving resident network information comprising a PLMNID of a PLMN and sent by a second terminal device; determining whether the PLMN is an HPLMN of the first terminal device according to the PLMNID; and same being reselected to the HPLMN when it is determined that the PLMN is the HPLMN of the first terminal device. The embodiments of the present invention are applied to the process of HPLMN reselection.

Description

technical field [0001] The embodiment of the present invention relates to the field of communications, and in particular to a HPLMN reselection method and a terminal device. Background technique [0002] With the advancement of science and technology, wireless communication technology that can meet the needs of information exchange such as multimedia, diversification, globalization and personalization has emerged at the historic moment, and with the continuous development of communication technology, the network realized by wireless communication technology, that is, wireless The application of communication network is also more and more extensive. The wireless communication network built by the operator is called a public land mobile network (Public Land Mobile Network, PLMN), and different operators may build their own PLMN. Among them, the PLMN built by the operator contracted with the user is called the user's home network, which is usually represented by the home publi...
