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.

1. A method for defining User Equipment (UE) behavior when an independent granular network access control is indicated by a network, wherein said method comprises:
receiving at least one granular category in an indication from said network after a requesting application initiates a service request to access said network; checking whether said requesting application belongs to said at least one granular category independent of said barred category by said UE; confirming whether said granular category of said requesting application belongs to said barred category; and holding said service request till an access barring is alleviated for said granular category, if said granular category of said requesting application belongs to said barred category.
