METHOD AND DEVICE FOR PROVIDING LOCAL DATA NETWORK INFORMATION TO TERMINAL IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17923086 titled 'METHOD AND DEVICE FOR PROVIDING LOCAL DATA NETWORK INFORMATION TO TERMINAL IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The present disclosure is about a method for providing local data network information to a terminal in a wireless communication system. The method involves deciding to add a protocol data unit (PDU) session anchor-user plane function (PSA-UPF) based on the mobility of the terminal. The PDU session is then established with the added PSA-UPF, and a PDU path is configured for the downlink and uplink between the PSA-UPF and the terminal. Finally, a PDU session modification command is transmitted to the terminal to instruct the addition of a new PSA-UPF.

  • The method involves providing local data network information to a terminal in a wireless communication system.
  • The decision to add a PSA-UPF is based on the mobility of the terminal.
  • The PDU session is established with the added PSA-UPF.
  • A PDU path is configured for the downlink and uplink between the PSA-UPF and the terminal.
  • A PDU session modification command is transmitted to the terminal to instruct the addition of a new PSA-UPF.

Potential applications of this technology:

  • This technology can be applied in 5G or pre-5G communication systems to support higher data transmission rates.
  • It can be used to enhance the performance and efficiency of communication systems beyond 4G LTE.
  • The method can be implemented in wireless networks to improve the overall user experience and enable faster data transmission.

Problems solved by this technology:

  • The method solves the problem of providing local data network information to a terminal in a wireless communication system.
  • It addresses the challenge of deciding when to add a PSA-UPF based on the mobility of the terminal.
  • The method solves the problem of establishing a PDU session and configuring a PDU path for efficient data transmission.

Benefits of this technology:

  • This technology enables higher data transmission rates beyond 4G LTE systems.
  • It improves the overall performance and efficiency of wireless communication systems.
  • The method enhances the user experience by enabling faster data transmission and improved connectivity.


Original Abstract Submitted

The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a higher data transmission rate beyond a 4G communication system such as LTE. A method, according to one embodiment of the present disclosure, is a method for providing local data network information to a terminal from a session management function (SMF) entity in a wireless communication system, the method comprising the steps of: according to the mobility of a terminal, deciding, on the basis of first information, to add a protocol data unit (PDU) session anchor-user plane function (PSA-UPF) for a PDU session; establishing the PDU session with the PSA-UPF which has been decided to be added; configuring a PDU path for a downlink and an uplink between the PSA-UPF and the terminal; and transmitting, to the terminal, a PDU session modification command for instructing the addition of a new PSA-UPF, wherein the first information may include at least one among policy and charging control (PCC) information, and local data network (DN) configuration information which is received from a policy control function (PCF) entity.
