Public land mobile network (PLMN) identification switching method, base station and communication network

Abstract

An embodiment of the invention provides public land mobile network (PLMN) identification switching method, base station and communication network and relates to the field of communication. The base station can control user equipment to perform PLMN identification switching. The method includes: by the base station, acquiring a first PLMN identification list; by the base station, controlling the user equipment to perform PLMN identification switching according to the first PLMN identification list; wherein the first PLMN identification list is configured by the base station and used for indicating the switchable PLMN identifications corresponding to each first identification currently supported by the base station, each first identification comprises one or more of a base station identification, an operator identification and a cell identification, and the PLMN identification switching includes network switching and network reorientation. The PLMN identification switching method, base station and communication network is applicable to PLMN switching.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for switching between public land mobile network identities, a base station and a communication network. Background technique [0002] In a wireless mobile network, the coverage of each cell is limited, and UE (User Equipment, user equipment) often needs to be handed over due to movement or other reasons to ensure service continuity. [0003] In the prior art, when an operator needs a user to switch between multiple PLMN id (Public Land Mobile Network identification, public land mobile network identification) mobile networks, the MME (Mobility Management Entity, mobile management entity) of the core network sends The base station sends an HRL (Handover Restriction List, Handover Restriction List), which contains an EPLMN (Equivalent PLMN, equivalent public land mobile network) list, and the EPLMN list also contains a list of PLMN identities of multiple mobile operators. The PL...

[0004] However, the HRL provided by the core network in the existing network is an optional field, and some core networks may not support this field

When the base station needs to perform handover between PLMN identities, but the core network cannot support HRL, the base station cannot know whether to perform handover between PLMN identities and which PLMN identities can be used as handover targets, so it cannot perform handover between PLMN identities
