Abstract
The method for joining a multicast broadcast service (MBS) session includes: receiving, by the network device, MBS information sent by a User Equipment, UE; determining according to the MBS information, by the network device, information of a first Session Management Function, SMF, that currently serves an MBS session corresponding to the MBS information; and sending, by the network device, the MBS information to the first SMF according to the information of the first SMF, so that the first SMF handles the UE joining into the MBS session. In this way, the network device obtains the SMF that currently serves the MBS session by querying, so that one MBS session is only served by one SMF, avoiding the situation that SMFs serve the same MBS session, and simplifying the MBS session management.
