Abstract

The embodiment of the invention provides a network redirection method and device and user equipment. According to the technical scheme, when the user equipment is in network redirection, a target cell is searched on a target frequency point specified by a network side; and if the public land mobile network PLMN of the target cell is an unidentified PLMN, the user equipment takes the target cell as a cell of an equivalent public land mobile network EPLMN, and initiates network registration to the target cell. According to the technical scheme, when the user equipment is in network redirection, if the searched target cell belongs to the unidentified PLMN, the target cell is taken as a cell of the RPLMN to initiate network registration, so that the problem of network redirection failure caused by the fact that the user equipment does not initiate network registration to the unidentified PLMN in the prior art is solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a network redirection method, device, and user equipment. Background technique [0002] With the continuous update of the network system, changes in the network planning of various operators, and the construction of inter-network roaming and other factors, operators may add new PLMNs on the basis of their original PLMNs, thereby adding new PLMN identifiers. Newly added PLMN identities, especially some PLMN identities that are still in the testing stage and have not been officially used by operators may not be recognized by some user equipment, and belong to unrecognized PLMNs. [0003] According to the existing protocol, the user equipment will only initiate registration with an unidentified PLMN when there is no network, but in the network redirection scenario, it will not initiate registration with an unidentified PLMN, resulting in netwo...
