    Abstract: This application provides a handover control method, an admission control method, and a communication apparatus. A first access network device obtains mapping information between an access network slice instance of a second access network device and a network slice; the first access network device determines, based on the mapping information, that the second access network device supports a first network slice associated with a service currently performed by a terminal device; and the first access network device sends first request information to the second access network device, where the first request information is used to request to enable the terminal device to access the second access network device, and then the second access network device performs admission control. In this technical solution, continuity of a network slice service can be ensured when the terminal device performs handover between access network devices, and impact on a core network can be reduced.

    Abstract: This application provides a communication method and a communication apparatus. A terminal device receives first information, where the first information indicates at least one supported network slice, the at least one supported network slice includes a network slice supported by a first cell and/or a network slice supported by a first access device, the first cell includes a cell currently accessed by the terminal device, and the first access device includes an access device currently accessed by the terminal device; the terminal device receives second information, where the second information indicates at least one allowed network slice; and the terminal device processes a session establishment request of a first service based on the first information and the second information, so that a waste of resources for transmission of the session establishment request can be reduced.

    Abstract: A communication method and a communication apparatus are provided to send, to a terminal device by using an RRC message, information about at least one first network slice corresponding to a first identifier. The method includes: a first access network device broadcasts a first identifier, where the first identifier identifies information about a first access network slice; and the first access network device sends a radio resource control RRC message to a terminal device, where the RRC message includes information about at least one first network slice corresponding to the first identifier.

    Abstract: The present disclosure relates to methods and communication apparatus for providing a network slice. In one example method where an access network device accessed by a terminal device does not support a network slice requested by the terminal device, the terminal device sends a network slice identifier, corresponding to a protocol data unit (PDU) session, to the access network device by including the network slice identifier in an radio resource control (RRC) message. The access network device may learn of the network slice identifier, and when the access network device does not support the network slice, search, in an access network device corresponding to a neighboring cell, for a target second access network device that supports the network slice.

    Abstract: 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.
