Handover method, base station and communication network between public land mobile network identities

Abstract

Embodiments of the present invention provide a method for handover between public land mobile network identifications, a base station, and a communications network, so that a base station can control user equipment to be handed over between PLMN identifications. The method for handover between PLMN identifications includes: acquiring, by a base station, a first PLMN identification list, where the first PLMN identification list is configured by the base station and is used for indicating a handover allowed PLMN identification corresponding to each first identification currently supported by the base station, and the first identification includes one or more of a base station identification, an operator identifier, and a cell identifier; and controlling, by the base station according to the first PLMN identification list, user equipment to be handed over between PLMN identifications, where the handover between the PLMN identifications includes network handover and network redirection. The method for handover between public land mobile network identifications, the base station, and the communications network provided in the embodiments of the present invention are used for handover between public land mobile networks.

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 MobileNetwork identification, public land mobile network identification) mobile networks, the MME (Mobility Management Entity, mobile management entity) of the core network sends a Send HRL (Handover Restriction List, handover restriction list), the HRL contains EPLMN (Equivalent PLMN, equivalent public land mobile network) list, the EPLMN list contains multiple mobile operators PLMN identification list, the base station can according to the PLM...

Problems solved by technology

[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
