Problems solved by technology
[0003] However, in the existing technology, for terminal devices that have signed different service packages under the same DNN, the SMF network element discovery strategy adopted is the same when the session is activated, so the existing technology cannot meet the operator's service package deployment requirements

The embodiment of the invention provides a session management network element discovery method, device and system, relates to the field of communication, and can provide differentiated session management network element discovery strategies for terminal devices signed with different service packages under the same DNN. The method specifically comprises the following steps: a network function storage function network element receives a first identifier from a mobile management network element, wherein the first identifier is used for identifying an attribution of terminal equipment; the network function storage function network element determines a first session management network element according to the first identifier, and an attribution identifier of the first session management network element is the same as the first identifier; and the network function storage function network element sends the identifier of the first session management network element to the mobile management network element. The method is used for discovering the session management network element.
Description
technical field [0001] The present application relates to the communication field, in particular to a method, device and system for session management network element discovery. Background technique [0002] At present, in the fifth generation (the 5th, 5G) network, some operators expect to adopt different session management functions for different service packages with the same data network name (DNN) when planning service packages. (session management funcion, SMF) network element discovery policy. For example, such as the general package and specific package of enhanced mobile broadband (eMBB) service, the DNN of the two service packages is the same (both are eMBB services), but in the cross-region access scenario, the operator may wish to A terminal device that subscribes to the general package of the eMBB service selects the visited SMF network element for services; while a terminal device that subscribes to a specific service package for the eMBB service selects the h...
