METHODS AND NODES FOR FACILITATING A PDU SESSION PROCEDURE IN INTERWORKING NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18151387 titled 'METHODS AND NODES FOR FACILITATING A PDU SESSION PROCEDURE IN INTERWORKING NETWORKS
Simplified Explanation
The abstract describes a method for facilitating a Protocol Data Unit (PDU) session procedure for a User Equipment (UE) in a 5th Generation System (5GS) network that is interworking with an Evolved Packet System (EPS) network. The method involves selecting a Packet Data Network Gateway Control plane Function+Session Management Function (PGW-C+SMF) to manage the PDU session and determining whether the PDU session supports interworking with the EPS network based on the UE's capability and subscription data. An indication is then sent to the PGW-C+SMF to indicate whether the PDU session supports interworking with the EPS network.
- The method is used in a 5GS network that is interworking with an EPS network.
- It involves selecting a PGW-C+SMF to manage the PDU session.
- The method determines whether the PDU session supports interworking with the EPS network based on the UE's capability and subscription data.
- An indication is sent to the PGW-C+SMF to indicate the interworking support of the PDU session.
Potential Applications
- This method can be applied in 5G networks that are interworking with existing EPS networks.
- It can be used to facilitate seamless communication between different generations of networks.
- The method ensures efficient management of PDU sessions in interworking scenarios.
Problems Solved
- The method solves the problem of managing PDU sessions in a 5GS network that is interworking with an EPS network.
- It addresses the challenge of determining the interworking support of PDU sessions based on UE capability and subscription data.
Benefits
- The method simplifies the process of managing PDU sessions in interworking scenarios.
- It ensures seamless communication between different generations of networks.
- The method improves the efficiency of PDU session management in 5GS networks.
Original Abstract Submitted
A method at an Access and mobility Management Function (AMF) for facilitating a Protocol Data Unit (PDU) session procedure for a User Equipment (UE) in a 5th Generation System (5GS) network, wherein the 5GS network is interworking with an Evolved Packet System (EPS) network, and a Packet Data Network Gateway Control plane Function+Session Management Function (PGW-C+SMF) supporting the interworking is selected for managing the PDU session. The method comprises determining whether the PDU session supports interworking with the EPS network, based on at least one of a capability of the UE and a subscription data of the UE; and sending an indication which indicates whether the PDU session supports interworking with the EPS network to the PGW-C+SMF.
