ENSURING NETWORK CONTROL OF SIMULTANEOUS ACCESS TO NETWORK SLICES WITH APPLICATION AWARENESS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18029931 titled 'ENSURING NETWORK CONTROL OF SIMULTANEOUS ACCESS TO NETWORK SLICES WITH APPLICATION AWARENESS

Simplified Explanation

This patent application describes a system and method for controlling access to network slices with application awareness in a cellular communications system.

  • The method involves a wireless communication device sending application identifiers (IDs) to a Policy and Control Function (PCF) via an Access and Mobility Management Function (AMF).
  • The wireless communication device then receives User Equipment (UE) Route Selection Policy (URSP) rules from the PCF via the AMF, which are based on the application IDs.
  • The PCF obtains information about mutually exclusive network slices and generates URSP rules based on the application IDs and the information about the network slices.
  • The PCF then sends the URSP rules to the wireless communication device via the AMF.


Original Abstract Submitted

Systems and methods are disclosed herein for ensuring network control of simultaneous access to network slices with application awareness. In one embodiment, a method performed in a cellular communications system comprises, at a wireless communication device, sending, to a Policy and Control Function (PCF) via an Access and Mobility Management Function (AMF), application identifiers (IDs) of applications used by the wireless communication device and receiving, from the PCF via the AMF, one or more User Equipment (UE) Route Selection Policy (URSP) rules that are based on the application IDs. The method further comprises, at the PCF, obtaining information about one or more mutually exclusive network slices, generating the one or more URSP rules based on the application IDs and the information about the one or more mutually exclusive network slices, and sending the one or more URSP rules to the wireless communication device via the AMF.
