摘要： 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.

摘要： 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.
