Granular network access control and methods thereof
First Claim
1. A method by a base station, the method comprises:
- determining a system information block (SIB) including an application category to be barred and a value related to a barring timer; and
transmitting the SIB to the terminal,wherein, if a service request for an application is triggered, whether a category of the requested application belongs to the application category to be barred is checked,wherein whether the service request is to be held is determined in response to the checking result, andwherein the service request is held until the barring timer is expired.

Abstract
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.

6. A base station, the base station comprising:
-
a transceiver; and at least one processor configured to; determine a system information block (SIB) including an application category to be barred and a value related to a barring timer; and transmit the SIB to the terminal, wherein, if a service request for an application is triggered, whether a category of the requested application belongs to the application category to be barred is checked, wherein whether the service request is to be held is determined in response to the checking result, and wherein the service request is held until the barring timer is expired. - View Dependent Claims (7, 8, 9, 10)

11. A method by a terminal, the method comprising:
-
receiving a system information block (SIB) including an application category to be barred and a value related to a barring timer from a network; identifying, if a service request for an application is triggered, a category of the requested application; checking whether the category of the requested application belongs to the application category to be barred; determining whether the terminal holds the service request in response to the checking result; and holding the service request until the barring timer is expired. - View Dependent Claims (12, 13)

14. A terminal comprising:
-
a transceiver; and at least one processor configured to; receive a system information block (SIB) including an application category to be barred and a value related to a barring timer from a network, identify, if a service request for an application is triggered, a category of the requested application, check whether the category of the requested application belongs to the application category to be barred, determine whether the terminal holds the service request in response to the checking result, and hold the service request until the barring timer is expired. - View Dependent Claims (15, 16)
