Abstract: A network entity is proposed for controlling the use, by a user equipment, of network slices of a communication network comprising a plurality of slice support areas. Each slice support area comprises at least one cell, and all cells of a given slice support area support the same network slices. A registration area for the registration of the user equipment with the communication network comprises at least one slice support area. The network entity is adapted to transmit, to the user equipment, slice support information for at least one slice support area of the communication network. The slice support information for a given slice support area indicates at least one network slice supported by the given slice support area and/or at least one network slice not supported by the given slice support area.

Abstract: The disclosure provides data transmission methods and apparatuses. One example method includes when the terminal device needs to perform the cross-network movement, the terminal device sends a message to a network element of a network accessed by the terminal device, to notify that the terminal device is to perform the cross-network movement from a source network to a target network. Therefore, during the movement of the terminal device, a network side pauses transmission of user plane data of the terminal device, and buffers data that is not sent before the terminal device performs the cross-network movement. After accessing the target network, the network side sends the buffered data to the terminal device.

Abstract: This application relates to the field of communications technologies, and discloses a method and apparatus. The method includes: A real base station receives a first uplink NAS message and an identifier of a first device. The real base station obtains a first hash value of first system information of a cell corresponding to the identifier of the first device. The real base station sends an N2 message to a core network device, where the N2 message includes the first uplink NAS message and the first hash value of the first system information. The core network device receives the N2 message from the real base station, and sends an integrity protected first downlink NAS message to a terminal, where the first downlink NAS message is forwarded by the real base station to the terminal, and the first downlink NAS message includes the first hash value of the first system information.
