AI Technical Summary

Technical Problem

In 5G communication systems, resource quota management of network slices is difficult to effectively handle, and when the network slice resources that the user equipment (UE) attempts to access has reached its upper limit, it is difficult for the prior art to gracefully handle the conversion of rejection and resource availability.

Method used

By introducing a backoff timer mechanism between the user equipment (UE) and the network entity, when the resource quota reaches the upper limit, the access request is rejected and the timer is set, and the registration is attempted after the timer expires to avoid resource waste.

Benefits of technology

It achieves graceful processing of access requests when the resource quota reaches the upper limit, avoid resource waste, and improves the system's resource utilization efficiency and user experience.

Abstract

A method performed by a user equipment (UE) in a wireless communication system, comprising: sending a registration request message including network slice assistance information (NSSAI) corresponding to a slice to a network entity; receiving a response message including rejection information about registration for the slice when resource allocation has reached an upper limit; and determining to suspend the registration request for the slice based on the response message, wherein the rejection information about registration for the slice includes information about a backoff timer or information about a rejection reason.
