Abstract: This application discloses a load relocation method, apparatus, and a system. The method includes determining, by a communications network entity, a target access management entity for load relocation; and sending, to an access network entity, an identifier of an original access management entity and an identifier of the target access management entity or an address of the target access management entity with respect to the access network entity. The access network entity sends a message from a user equipment (UE) to the target access management entity based on the identifier of the original access management entity carried in the message from the UE. In the foregoing solution, signaling overheads in a load relocation process are reduced and load relocation efficiency is improved.

Abstract: A congestion/overload control method and apparatus are provided. The method includes: learning, by a gateway device, information about network access time of a User Equipment (UE) or UE group; and rejecting or discarding, by the gateway device, session management request messages of the UE or UEs in the UE group beyond the network access time of the UE or UE group; or discarding, by the gateway device, data of the UE or the UEs in the UE group beyond the network access time of the UE or UE group. Embodiments of the present invention can perform congestion/overload control differentially on the UE or UEs in the group, implement congestion/overload control on the gateway device, avoid congestion/overload caused by a large number of UEs on the gateway device, and improve the efficiency of congestion/overload control.

Abstract: A method, device and system for creating resources during a user equipment (UE) hands over from a non-3rd Generation Partnership Project (non-3GPP) system to a 3GPP system are provided. A serving gateway (Serving GW) receives a first resource request message, such as Create Default Bearer Request message, including handover indication information indicating the handover from a mobility management network device, e.g., a MME. As the received resource request message includes the handover indication information, the Serving GW includes the handover indication information in a second resource request message and then sends the second resource request message to a PDN GW. After receiving the second resource request message, the PDN GW policy and charging control (PCC) rules to be used by the UE in the 3GPP access system so as to create the resources used by the UE in the 3GPP system.

Abstract: A session management method, device, and system, such that a terminal can access a local data network using a local user plane function (UPF) network element even when the terminal is out of a management area of a remote anchor session management function (SMF) network element. The method includes: receiving, by an intermediate session management network element, one or more local data network access identifiers (DNAIs); and determining, by the intermediate session management network element, a target DNAI based on current location information of a terminal and the one or more local DNAIs, where the target DNAI is used to select a local session management network element for the terminal.
