Abstract: A quality of service (QoS) parameter processing method and a system, where the method includes a session management function device obtaining a core network (CN) packet delay budget (PDB) between a first access network device and a first user plane function device, and sending the CN PDB to the first access network device via a context update response message, where the first access network device is a target access network device serving a terminal device after a handover. After receiving the CN PDB, the first access network device determines an access network (AN) PDB between the terminal device and the first access network device based on the CN PDB and an end-to-end PDB between the terminal device and the first user plane function device, and then schedules an air interface resource between the terminal device and the first access network device based on the AN PDB.

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.
