Abstract: An information indication method is provided, including: A terminal-side device receives first higher layer signaling from a network-side device, where the first higher layer signaling is used to configure N bandwidth parts BWPs, and N is a positive integer. The terminal-side device receives downlink control information from the network-side device, where the downlink control information includes an indication field. When N is less than a maximum quantity of BWPs that can be configured through the first higher layer signaling when the terminal-side device is in a connected mode (for example, an RRC connected mode) or a maximum quantity of BWPs that can be determined by using candidate bit states of the indication field that is used to determine an active BWP and that is in the downlink control information, the indication field indicates a position of the active BWP located in an initial BWP and the N BWPs.

Abstract: A congestion/overload control method and apparatus are provided. The method includes: learning, by a gateway device, information about network access time of a User Equipment (UE) or UE group; and rejecting or discarding, by the gateway device, session management request messages of the UE or UEs in the UE group beyond the network access time of the UE or UE group; or discarding, by the gateway device, data of the UE or the UEs in the UE group beyond the network access time of the UE or UE group. Embodiments of the present invention can perform congestion/overload control differentially on the UE or UEs in the group, implement congestion/overload control on the gateway device, avoid congestion/overload caused by a large number of UEs on the gateway device, and improve the efficiency of congestion/overload control.

Abstract: The present disclosure relates to a user data processing apparatus and method, and a system. In the user data processing apparatus disclosure, an interface management unit receives user data; at least two service units process the user data, where the at least two service units include a session unit and at least one of a bearer unit, a service flow unit, or a content unit; the interface management unit determines the session unit configured to process the user data, and sends the received user data to the determined session unit; and the session unit determines another service unit configured to process the user data. After receiving the user data, the GW-U determines the service unit configured to process the user data, and processes the user data by using the service unit determined by the GW-U. This improves processing flexibility of the GW-U.
