GRANULAR NETWORK ACCESS CONTROL AND METHODS THEREOF

摘要

A method and system that enhances the existing access barring mechanism as specified in the current 3GPP specification is disclosed. The method disclosed provides enhancing the access barring mechanism to accommodate application level barring between the User equipment (UE) and the network. The method disclosed individually restricts or permits access of network to every requesting application on the UE, based on granular category of the application and priority levels of the application within the granular category. The method disclosed also specifies handling of back-off timers; reject cause values and Access Point Name (APN) configuration by Access Stratum (AS) and Non Access Stratum (NAS) layer to support application level barring of UEs using the enhanced access barring mechanism. The enhanced access barring mechanism enables providing service to applications independent of other barred applications or priorities. The method disclosed provides a mechanism for access control for connected mode UEs.
