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: Embodiments of the present disclosure provide an anchor gateway switching method, apparatus, and system. The method includes: determining, by a control plane (CP) device, to switch a source anchor gateway; obtaining, by the CP device, location information of a terminal; determining, by the CP device, a target anchor gateway based on the location information; and sending, by the CP device, a modification request message to an software defined network (SDN) controller, where the modification request message includes an identifier of the terminal and an identifier of the target anchor gateway, the modification request message is used to notify the SDN controller to: update, based on the identifier of the terminal and the identifier of the target anchor gateway, a forwarding flow table corresponding to a downlink packet, and send an updated forwarding flow table to an SDN switch

Abstract: A method for establishing a tunnel between local gateways, and a gateway are disclosed. The method includes: determining, by an RGW, that UE is handed over from an S-LGW to a T-LGW, where before the UE is handed over, a packet of a local service of the UE is forwarded by the S-LGW between the UE and an application server of the local service, and the local service includes a same service that is deployed on the S-LGW and that is accessed by the UE before and after the UE is handed over; sending, by the RGW to the S-LGW and the T-LGW respectively, a first request message and a second request message to request to establish a tunnel, where the tunnel is used to transmit the packet of the local service between the S-LGW and the T-LGW; and establishing the tunnel between the S-LGW and the T-LGW.

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.
