摘要： A communication method applied to an integrated access and backhaul (IAB) system includes: a child node receives a first radio resource control (RRC) reconfiguration message from an access network device via a parent node, where the first RRC reconfiguration message includes a random access-free indication. The child node starts a timer. The child node sends a first RRC reconfiguration complete message to the access network device via the parent node. The child node receives first indication information from the parent node, where the first indication information indicates to stop the timer. The child node stops the timer.

摘要： 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.

摘要： 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.

摘要： This disclosure relates to a terminal device, a network device, a method of cell selection, and a wireless communications system. In the method of cell selection, a terminal device sends cell information of at least one cell in a first wireless communications system to a second network device in a second wireless communications system, so that the second network device can select a target cell in the first wireless communications system, and the terminal device accesses the target cell selected by the second network device, and accesses a core network in the first wireless communications system by using a first network device to which the target cell belongs. The terminal device provides the cell information, and the second network device selects the target cell. This implements cell selection in the future evolved first wireless communications system.
