Embodiment Construction

[0066] In order to solve the above technical problems, the general idea of ​​the technical solution in the embodiment of the present invention is as follows:

[0067] A session management method and device, when the UE is in an idle state in the non-3GPP access, if a data notification request for the PDU session of the UE in the non-3GPP access is received, according to the obtained user Judging whether to page the UE through the 3GPP access or send a notification message to the UE through the 3GPP access based on the information representing whether the PDU session can be reactivated in the 3GPP access, or further combine the Whether the UE can enter the connected state in the non-3GPP access determines whether to page the UE through the 3GPP access.

[0068] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation met...

Abstract

The present invention discloses a session management method and device. When a UE is in an idle state in the non-3GPP access, if a data notification request for a PDU session of the UE in the non-3GPP access is received, then judging whether to page the UE through the 3GPP access or send a notification message to the UE through the 3GPP access according to the obtained information indicating whether the PDU session can be reactivated in the 3GPP access, or Furthermore, judging whether to use the 3GPP access to page the UE in consideration of whether there is an available non-3GPP access around the UE solves the technical problem of waste of paging resources in the session management process in the prior art.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a session management method and device. Background technique [0002] UE (User Equipment, user terminal) is connected to the core network network architecture through 3GPP (3rd Generation Partnership Project, third generation partnership project) access and non-3GPP access, such as figure 1 shown. figure 1 The explanation of each flag in is as follows: [0003] HPLMN (Home Public Land Mobile Network, Home Public Land Mobile Network); [0004] AMF (Access Control And Mobility Management Function, access control and mobility management function); [0005] SMF (Session Management Function, session management function); [0006] IWF (Inter Working Function, interoperability function); [0007] UPF (User Plane Function, user plane function); [0008] N1, N2, N3, N4, N6, N11, NWu, Y1 and Y2 are communication interfaces in the network architecture. [0009] For a U...
