Title:
METHOD FOR IMPLEMENTING MULTICAST BROADCAST SERVICE SWITCHING, AND RELATED DEVICES
Document Type and Number:
WIPO Patent Application WO/2022/171122
Kind Code:
A1
Abstract:
Provided are a method for implementing multicast broadcast service switching, and related devices. The method is applied to an SMF corresponding to a user equipment, wherein a source base station that the user equipment accesses before switching supports an MBS, the user equipment has established an MBS session at the source base station before switching, and a target base station that the user equipment accesses after switching does not support the MBS. The method comprises: acquiring a PDU session associated with an MBS session, wherein S-NSSAI of the PDU session is the same as S-NSSAI of the MBS session, and the DNN of the PDU session is the same as a DNN of the MBS session; acquiring an MBS session identifier of the MBS session; acquiring, according to the MBS session identifier and from a PCF, policy rule information corresponding to the activated MBS session, wherein there is one or more pieces of policy rule information; and according to the policy rule information corresponding to the activated MBS session, establishing, on the PDU session, a quality-of-service stream corresponding to the activated MBS session, wherein there is one or more quality-of-service streams.
