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.

Abstract: Embodiments of the present disclosure disclose a function scheduling method, a device, and a system. The method includes: sending, by a control plane network element, a first request to a user plane network element, where the first request is used to request the user plane network element to perform a first function, and the first function is a function supported by both the control plane network element and the user plane network element; and disabling, by the control plane network element, the first function. In the solutions of the embodiments of the present disclosure, a function supported by both the user plane network element and the control plane network element can be flexibly processed.

Abstract: The present disclosure relates to the field of wireless communications technologies, and provides a communication method. The method includes: receiving, by a control plane entity (CPE), a request message, where the request message includes identification information of user equipment (UE); determining, by the CPE, whether a suspend function of the UE corresponding to the identification information is allowed to be enabled; and if the CPE determines that the suspend function of the UE is allowed to be enabled, sending, by the CPE, a message to a radio access network node (RAN node) connected to the UE, where the message includes indication information indicating that the suspend function is allowed to be enabled.

Abstract: Embodiments of the present disclosure disclose example service flow transmission methods and apparatus. One example method includes where a first gateway device determines a target service currently performed by UE, performs a bearer processing operation to obtain a target bearer corresponding to the target service, and binds a service flow of the target service to the target bearer. The first gateway device anchors the target bearer to a target gateway, and implements, by using the target gateway, service flow transmission between the UE and a network that corresponds to the target service. In some instances, a service flow can be bound to a bearer obtained after performing a bearer operation and the bearer can be anchored to an appropriate gateway.

Abstract: In a communication method, when a terminal device initiates establishment of a session of an Ethernet type, a virtual local area network management function entity in a communications system may determine a virtual local area network identifier of a user group to which the terminal device belongs. In this way, a user plane function entity in the session of the terminal device may allocate a plurality of virtual ports to a virtual local area network whose identifier is the virtual local area network identifier and may broadcast the Ethernet broadcast frame on the plurality of virtual ports.
