Abstract: The present invention discloses a wireless network access control method and an apparatus. The method includes: configuring, by a wireless network, an independent access control parameter for each network slice, so as to implement differential access control, by the network, on access to different network slices that is initiated by a terminal device. In addition, a core network or a radio access network initiates network slice overload control or a network slice access control parameter adjustment based on resource usage of each network slice in the network. By separately controlling and adjusting the access control parameter of each network slice, it is ensured that impact between network slices is minimized.

Abstract: This application provides a mobility management method and a communication apparatus. The method includes: A first DU receives a first measurement result reported by a terminal device, determines, based on the first measurement result, target beam information for the terminal device to perform mobility management and/or a target cell corresponding to the target beam information, notifies a CU of the target beam information and/or the target cell, and requests, through the CU, a second DU to confirm whether to accept the target beam information and/or the target cell. The first measurement result includes measurement results corresponding to a current serving cell of the terminal device and at least one non-serving cell of the terminal device.

Abstract: A communication method and apparatus. The method may be applied to a 4G system, a 5G system, and/or a future communication system such as a 6G system. The method includes: a splitting protocol layer entity of a terminal device configures a first sequence number SN of a splitting protocol layer in a first splitting protocol layer data packet, and configures a second SN of the splitting protocol layer in a second splitting protocol layer data packet. The splitting protocol layer entity of the terminal device sends the first splitting protocol layer data packet to a first protocol layer entity corresponding to a first access network device, and sends the second splitting protocol layer data packet to a first protocol layer entity corresponding to a second access network device.

Abstract: A radio access network RAN device receives a first message, where the first message includes identifiers of one or more first network slices, and the identifiers of the one or more first network slices are the same as identifiers that are of the one or more first network slices and that are included in a non-access stratum NAS request message sent by a terminal device to a core network CN device by using the RAN device; and the RAN device sends a second message including network slice redirection information to the terminal device, where the network slice redirection information includes at least one of network slice remapping information and terminal device redirection information, and the network slice redirection information is obtained after the RAN device performs network slice redirection decision-making on the one or more first network slices.
