SYSTEM AND METHODS FOR USER EQUIPMENT STORING REJECTED NETWORK SLICE SELECTION ASSISTANCE INFORMATION PER ACCESS TYPE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17815502 titled 'SYSTEM AND METHODS FOR USER EQUIPMENT STORING REJECTED NETWORK SLICE SELECTION ASSISTANCE INFORMATION PER ACCESS TYPE

Simplified Explanation

The patent application describes a method and system for maintaining rejected network slice selection assistance information (NSSAI) in User Equipment (UE) when Single Network Slice Selection Assistance Information (S-NSSAI) is not available due to the maximum number of UEs reached per access type.

  • The UE receives a Non-Access Stratum (NAS) message from the network, which includes information about rejected S-NSSAI(s) and the cause for their unavailability.
  • Based on the received S-NSSAI(s) information, the UE determines the access type on which the rejected S-NSSAI(s) is applicable.
  • The UE then maintains a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of UEs reached per access type.

Potential applications of this technology:

  • This technology can be applied in cellular networks where network slicing is used to provide different services with varying requirements.
  • It can help in managing network resources efficiently by keeping track of rejected S-NSSAI(s) and their applicable access types.

Problems solved by this technology:

  • The method and system solve the problem of handling rejected S-NSSAI(s) when they are not available due to the maximum number of UEs reached per access type.
  • It allows the UE to maintain a record of rejected NSSAI for future reference and decision-making.

Benefits of this technology:

  • By maintaining rejected NSSAI information, the UE can avoid unnecessary rejections and improve the overall user experience.
  • It enables better resource allocation and management in the network by keeping track of rejected S-NSSAI(s) and their applicable access types.


Original Abstract Submitted

A method and system in the User Equipment (UE) for maintaining rejected network slice selection assistance information (NSSAI) for Single Network Slice Selection Assistance Information (S-NSSAI) not available due to maximum number of UEs reached per access type. The method comprises receiving a Non-Access Stratum (NAS) message including at least one of a registration accept, registration reject or CONFIGURATION UPDATE COMMAND message along with at least one of rejected Single Network Slice Selection Assistance Information (S-NSSAI(s)) information and a cause for the S-NSSAI not available due to maximum number of UEs reached from a network. Thereafter, the method includes determining by the UE an access type on which the rejected S-NSSAI(s) is applicable based on the received S-NSSAI(s) information and then maintaining a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of the UEs reached per access type based on the determination.
