Network slice multicast method and apparatus
A network slice multicast method includes generating, by an access network device, a first message. The network slice multicast method further includes sending, by the access network device, the first message to a user equipment (UE). The first message comprises a first network slice identifier and configuration information of a multicast traffic channel, and the first network slice identifier corresponds to the multicast traffic channel.

4. The method according to claim 1 , wherein the configuration information of the multicast traffic channel comprises at least one of:
a last subframe configuration, a data modulation and coding value, a scheduling period, a logic channel identifier, a duration timer, a discontinuous reception (DRX) inactivity timer, or a scheduling period start offset.
5. The method according to claim 1 , further comprising:
sending, by the access network device on the multicast traffic channel, multicast data corresponding to a network slice.
6. A network slice multicast method, comprising:
receiving, by a user equipment (UE), a first message from an access network device, wherein the first message comprises a network slice identifier and configuration information of a multicast traffic channel, and the network slice identifier corresponds to the multicast traffic channel; and
receiving, by the UE on the multicast traffic channel, multicast data corresponding to a network slice.
7. The method according to claim 6 , wherein the first message further comprises a temporary mobile group identity (TMGI), and the TMGI corresponds to the network slice identifier.
