METHOD AND APPARATUS FOR SUPPORTING PRIORITY OF NETWORK SLICE IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18143196 titled 'METHOD AND APPARATUS FOR SUPPORTING PRIORITY OF NETWORK SLICE IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application is about a communication system that supports high data transmission rates in 5G or 6G networks.

  • The system includes an Access and Mobility Management Function (AMF) entity that performs various tasks.
  • The AMF entity receives a registration request message from a User Equipment (UE) device, which includes a request for Network Slice Access Stratum (AS) Group (NSAG) information.
  • The AMF entity also receives NSAG information from another entity, which includes Single-Network Slice Selection Assistance Information (S-NSSAI) priority information and mapping information between S-NSSAI and NSAG identity.
  • The AMF entity transmits at least one of the NSAG information or NSAG Tracking Area (TA) boundary information to a Policy Control Function (PCF) entity.
  • The AMF entity receives NSAG priority information from the PCF entity based on the NSAG information.
  • Finally, the AMF entity transmits a registration response message to the UE, which includes at least one of the NSAG information, NSAG TA boundary information, or NSAG priority information.


Original Abstract Submitted

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) entity in a wireless communication system includes receiving, from a UE, a registration request message comprising a network slice access stratum (AS) group (NSAG) information request, receiving, from another entity, NSAG information including single-network slice selection assistance information (S-NSSAI) priority information and mapping information between the S-NSSAI and an NSAG identity, transmitting, to a policy control function (PCF) entity, at least one of the NSAG information or NSAG tracking area (TA) boundary information, receiving, from the PCF entity, NSAG priority information based on the NSAG information, and transmitting, to the UE, a registration response message including at least one of the NSAG information, the NSAG TA boundary information, or the NSAG priority information.
