Abstract: A communication method and apparatus includes: a network device separately sends configuration parameters of power saving signaling to terminal devices. Then, the network device sends downlink control information carrying the power saving signaling to the terminal device through a physical downlink control channel based on a payload of the DCI and/or a search space set. The configuration parameter of the power saving signaling includes the payload of the DCI and the search space set. The payload of the DCI indicates a quantity of bits of the DCI. The DCI is used to carry the power saving signaling and is transmitted through the physical downlink control channel (PDCCH). The search space set is used to determine a monitoring occasion of the PDCCH.

Abstract: The present disclosure relates to implementing policy control. In one example communication system, a core network exposes a service policy to an application server, and the application server authorizes user equipment with the service policy. Before accessing a service provided by the application server, the user equipment pushes, to the core network, the service policy that needs to be used to access the application server. A core network device performs policy control such as charging, QoS, routing, gating control, or redirection on a service flow or a data packet between the user equipment and the application server according to the service policy pushed by the user equipment.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a gateway system, so as resolve a technical problem of a complex network structure caused due to that different network architectures need different gateways. The gateway system provided in the present invention separates a control plane from a forwarding plane. A gateway controller is configured to complete a control function, and may control respective generation of control information for data packets of multiple different protocol types. A gateway forwarding device is responsible for forwarding, and may be controlled by the gateway controller to receive and send data packets of various protocol types. In a multi-standard access architecture, only one or few such gateway systems may need to be accessed instead of accessing multiple different gateways, thereby simplifying a network topology structure, and facilitating network maintenance.
