A system is disclosed in which a data network is associated with an application function (AF). When there is a change of data network access identifier (DNAI), a Session Management Function (SMF) sends a notification of a user plane management event to the application function (AF), and when a target data network is associated with another application function (target AF), the SMF also sends a notification of a user plane management event to the target AF.

This application discloses example application instance address translation methods. One example method includes receiving, by a control plane device from a mobile edge cloud control device, an address of a target application instance of an application service accessed by a terminal. The control plane device can then send the address of the target application instance to a first user plane device. The control plane device can then instruct the first user plane device to set, as the address of the target application instance, a destination address of an uplink packet that is of the terminal and is associated with the application service.

Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and equipment for handover are provided. The method includes informing, by a source base station, a source core network whether a direct data forwarding path is available, determining, by the source core network, whether to use direct data forwarding or indirect data forwarding, informing, by the source core network, a target core network of information of direct data forwarding, indirect data forwarding or data forwarding being not possible, informing, by the target core network, a target base station of the information of direct data forwarding, indirect data forwarding or data forwarding being not possible, and allocating, by the target base station, tunnel information for data forwarding.

A wireless User Equipment (UE) controls a wireless data service that is received from a wireless communication network over a radio band. In the wireless UE, a radio wirelessly exchanges user data with the communication network over the radio band to receive the wireless data service. The radio wirelessly receives a communication performance metric from the wireless communication network over the radio band. The communication performance metric characterizes the wireless data service received by the wireless UE over the radio band. In the wireless UE, user circuitry translates the communication performance metric into a service instruction for the wireless UE over the radio band. The radio wirelessly transfers the service instruction for the wireless UE to the wireless communication network over the radio band. The wireless communication network modifies the wireless data service for the wireless UE responsive to the service instruction.

A gateway station switching method and apparatus. When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station.
