摘要： An aspect of the disclosure provides a method of network slice management performed by a Communication Service Management Function (CSMF). The method includes receiving service requirements and receiving capability exposure information. The method further includes transmitting network slice requirements in accordance with the service requirements and capability exposure information. In some embodiments the capability exposure information is received from a Network Slice Management Function (NSMF). In some embodiments the network slice requirements are transmitted to the NSMF. Other aspects are directed to methods implemented by an NSMF and a Network Sub-Slice Management Function (NSSMF). Other aspects are directed to the network functions themselves.

摘要： This application provides an information transmission method when a terminal device accesses a serving radio access network (RAN) device. The terminal device receives an identifier of a first cluster-data function (C-DF) associated with the serving RAN device from the serving RAN device, where the first C-DF is located in a radio access network and stores current data of the terminal device. When the terminal device camps on the serving RAN device longer than or equal to a first threshold, the terminal device stores the identifier of the first C-DF.

摘要： This application discloses a communication method and apparatus. The method includes: receiving, by a first device, a first message, where the first device is a primary access network device of a terminal device in a first state, the terminal device in the first state does not send channel state information to the first device, and a core network device and the first device reserve a data plane connection of the terminal device in the first state; determining, by the first device based on the first message, that a second device is a secondary access network device of the terminal device in the first state; sending, by the first device, a second message to the second device, where the second message is used to request to add the second device as the secondary access network device of the terminal device in the first state.

摘要： 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.

摘要： Example network management methods and network devices are described. One example method includes obtaining a configuration parameter by a first network device. The configuration parameter includes a network slice instance identifier and an access and mobility management function identifier corresponding to the network slice instance identifier, and/or a network slice subnet instance identifier and an access and mobility management function identifier corresponding to the network slice subnet instance identifier. The first network device sends the configuration parameter to a second network device. According to embodiments of the present disclosure, a unique access and mobility management function corresponding to a network slice instance and/or a network slice subnet instance can be selected.
