Abstract: A network slice selection policy updating method and an apparatus are disclosed. The method includes sending, by a terminal device, configured network selection assistance information on the terminal device to an AMF, where the network selection assistance information includes a first slice identifier. The method further includes receiving, by the terminal device, allowed network selection assistance information and indication information that are returned by the AMF, where the allowed network selection assistance information includes a second slice identifier, and the indication information indicates that the second slice identifier corresponds to the first slice identifier. This can prevent the terminal device from initiating an unnecessary session establishment procedure, and save network resources.

Abstract: The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.

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.
