Title:
COMMUNICATION METHOD AND APPARATUS FOR MULTICAST AND BROADCAST SERVICE, AND MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/170817
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a communication method and apparatus for a multicast and broadcast service, and a medium and an electronic device. The communication method comprises: receiving a DM creation or update request sent by an NEF, wherein the DM creation or update request includes a data set identifier for indicating a user equipment policy, a data subset identifier for indicating that a data type is an MBS, a data keyword for indicating a multicast or broadcast address, a data sub-keyword for indicating network slice information and a data network name or for indicating an MBS session identifier, and a data set for indicating MBS data; sending a DM creation or update response to the NEF; and sending a DM notification request to a PCF, wherein the DM notification request is used for making the PCF transmit, to a UE, user equipment policy information indicating that a user equipment policy type is the MBS. By means of the technical solution of the present application, MBS information can be transmitted to a user equipment in a standardized manner, thereby reducing the development cost and test cost of the user equipment.
