Methods and nodes for facilitating a PDU session procedure in interworking networks

Abstract:

A method at a first node for facilitating a PDU session procedure for a UE in a first communication network, wherein the first communication network is interworking with a second communication network, and a second node supporting the interworking is selected for managing the PDU session, the method comprising: determining an indication which indicates whether the PDU session supports interworking with the second network; and sending the indication to the second node. According to various aspects and embodiments of the method, allocation of resources can be improved and the deployment can be simplified.
