Method, apparatus, and system for processing network sharing
First Claim
1. A method for processing network sharing, the method comprising:
- receiving, by a mobility management network element, an access request sent by a user equipment;
determining, by the mobility management network element, whether the user equipment supports network sharing;
selecting, by the mobility management network element, a circuit switched domain public land mobile network identifier (CS domain PLMN ID) to provide a service for the user equipment, wherein selecting, by the mobility management network element, the CS domain PLMN ID comprises;
sending, by the mobility management network element, a message to a prior mobility management element of the user equipment to obtain the CS domain PLMN ID;
when the user equipment does not support network sharing, sending, by the mobility management network element, a location update request message to a mobile switching center or visitor location register (MSC/VLR), wherein the location update request message comprises;
a location area identity (LAI) comprising a common public land mobile network identifier (PLMN ID), andthe CS domain PLMN ID selected by the mobility management network element; and
sending, by the mobility management network element, an access accept message to the user equipment, wherein the access accept message includes the LAI comprising the common PLMN ID to be used by the user equipment for accessing the MSC/VLR.
