APPARATUS AND METHOD FOR MANAGING USER PLANE FUNCTION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18457191 titled 'APPARATUS AND METHOD FOR MANAGING USER PLANE FUNCTION IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a method performed by an access and mobility management function (AMF) in a wireless communication system. The method involves receiving a registration request message from a user equipment (UE) with a packet data network (PDN) connection established. The registration request message includes a first single-network slice selection assistance information (S-NSSAI) associated with the PDN connection. The AMF determines a second S-NSSAI associated with a packet data unit (PDU) session corresponding to the PDN connection based on the first S-NSSAI. The AMF then transmits information regarding the second S-NSSAI to a user plane function (UPF) via a session management function (SMF) to request modification of N4 session.

  • The method involves receiving a registration request message from a UE with an established PDN connection.
  • The registration request message includes a first S-NSSAI associated with the PDN connection.
  • The AMF determines a second S-NSSAI associated with a PDU session based on the first S-NSSAI.
  • The AMF transmits information regarding the second S-NSSAI to a UPF via an SMF to request modification of N4 session.

Potential Applications

  • This technology can be applied in wireless communication systems to manage and modify network slices for different PDN connections and PDU sessions.
  • It can be used to optimize network resources and improve the overall performance of the wireless communication system.

Problems Solved

  • The method solves the problem of efficiently managing network slices and PDU sessions in a wireless communication system.
  • It provides a streamlined approach to modify N4 sessions based on the S-NSSAI associated with PDN connections and PDU sessions.

Benefits

  • The method simplifies the process of modifying N4 sessions by using S-NSSAI information.
  • It allows for better resource allocation and optimization in wireless communication systems.
  • The method improves the overall efficiency and performance of the network.


Original Abstract Submitted

In accordance with an embodiment of the disclosure, a method performed, by an access and mobility management function (AMF), in a wireless communication system, the method comprising receiving, from a user equipment (UE) with a packet data network (PDN) connection established, a registration request message including a first single-network slice selection assistance information (S-NSSAI) associated with the PDN connection, determining a second S-NSSAI associated with a packet data unit (PDU) session corresponding to the PDN connection based on the first S-NSSAI, and transmitting an information regarding the second S-NSSAI to a user plane function (UPF) via a session management function (SMF) to request modification of N4 session.
