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.

Claims

1. A method by a base station, the method comprises:

transmitting access information including a barring category and a value of timer to a terminal; and

receiving a service request for an application, if the service request is triggered and a category of the application does not belong to the barred category, wherein a transmission of the service request is barred until the value of timer is expired, if the category of the application belongs to the barred category.

2. The method of claim 1, wherein the application is deactivated until the value of timer is expired, if the category of the application belongs to the barred category and the application is running.

3. The method of claim 1, wherein the category includes at least one of an application category, traffic category, quality of service (QoS) category, a bearer type category, a logical channel group category, or a priority level category.

4. The method of claim 1, wherein the value of the timer is determined based on a priority level of the category of the application.

5. The method of claim 1, wherein each application in the terminal is mapped to the barred category.

6. The method of claim 1, wherein the access information is included in at least one of a system information message (SIB), a radio resource control (RRC) message, or a random access channel (RACH) reject message.

7. The method of claim 1, wherein the service request is transmitted via at least one of an explicit service request message, a packet data network (PDN) connectivity request, a bearer resource modification request, a scheduling request (SR), a buffer status report (BSR) message or a bearer resource allocation request.

8. A base station, the base station comprises:

a transceiver configured to receive and transmit a signal; and

at least one processor configured to;

transmit access information including a barring category and a value of timer to a terminal, and

receive a service request for an application, if the service request is triggered and a category of the application does not belong to the barred category,

wherein a transmission of the service request is barred until the value of timer is expired, if the category of the application belongs to the barred category.

9. The base station of claim 8, wherein the application is deactivated until the value of timer is expired, if the category of the application belongs to the barred category and the application is running.

10. The method of claim 8, wherein the category includes at least one of an application category, traffic category, quality of service (QoS) category, a bearer type category, a logical channel group category, or a priority level category.

11. The base station of claim 8, wherein the value of the timer is determined based on a priority level of the category of the application.

12. The base station of claim 8, wherein each application in the terminal is mapped to the barred category.

13. The base station of claim 8, wherein the access information is included in at least one of a system information message (SIB), a radio resource control (RRC) message, or a random access channel (RACH) reject message.

14. The base station of claim 8, wherein the service request is transmitted via at least one of an explicit service request message, a packet data network (PDN) connectivity request, a bearer resource modification request, a scheduling request (SR), a buffer status report (BSR) message or a bearer resource allocation request.
