Abstract

Access category management objects may be configured for use in support of access category configurations of a user equipment (UE). Various methods for a UE configuration with access categories are disclosed. Signaling methods by a radio access network of access barring parameters such as a signaling method for a partial list of access barring parameters with explicit signaling of access category indexes and a signaling method for a full list of access barring parameters where access categories are signaled using a bitmap are disclosed. Access control parameters and an access control architecture in terms of access control function distribution within the UE protocol sublayers, solutions that address the impact of access control in a connected mode on a buffer status report, logical channel prioritization and flow control between the UE AS and UE NAS, and details regarding access barring checks are also disclosed.

First claim

What is claimed is:

1. A wireless transmit/receive unit (WTRU) comprising:
a processor;
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving a non-access stratum (NAS) configuration message, the NAS configuration message comprising information associated with one or more operator-defined access category values, the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier;
upon determining to initiate an access attempt, determining that the access attempt is associated with the first operator-defined access category value;
receiving system information related to access category barring;
determining whether the access attempt is barred, based on the first operator-defined access category value the access attempt is associated with and based on the system information related to access category barring; and
on a condition that the access attempt is determined to not be barred, initiating a radio resource control (RRC) connection establishment procedure.

2. The WTRU of claim 1 , wherein, in addition to the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier, the first operator-defined access category value of the one or more operator-defined access category values is associated with an application.

3. The WTRU of claim 1 , wherein the information indicates that a second operator-defined access category value is associated with an application, and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

4. The WTRU of claim 1 , wherein the information indicates that a second operator-defined access category value is associated with a network slice, and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

5. The WTRU of claim 1 , wherein the information indicates that a second operator-defined access category value is associated with a quality-of-service class identifier (QCI), and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

6. A method, implemented by a wireless transmit-receive unit (WTRU), comprising:
receiving a non-access stratum (NAS) configuration message, the NAS configuration message comprising information associated with one or more operator-defined access category values, the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier;
upon determining to initiate an access attempt, determining that the access attempt is associated with the first operator-defined access category value;
receiving system information related to access category barring;
determining whether the access attempt is barred, based on the first operator-defined access category value the access attempt is associated with and based on the system information related to access category barring; and
on a condition that the access attempt is determined to not be barred, initiating a radio resource control (RRC) connection establishment procedure.

7. The method of claim 6 , wherein, in addition to the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier, the first operator-defined access category value of the one or more operator-defined access category values is associated with an application.

8. The method of claim 6 , wherein the information indicates that a second operator-defined access category value is associated with an application, and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

9. The method of claim 6 , wherein the information indicates that a second operator-defined access category value is associated with a network slice, and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

10. The method of claim 6 , wherein the information indicates that a second operator-defined access category value is associated with a quality-of-service class identifier (QCI), and upon the determining to initiate the access attempt, further determining that the access attempt is associated with the second operator-defined access category, and wherein the determining whether the access attempt is barred is further based on the second operator-defined access category value the access attempt is associated with.

11. A system comprising:
One or more processors; and
memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving a non-access stratum (NAS) configuration message, the NAS configuration message comprising information associated with one or more operator-defined access category values, the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier;
upon determining to initiate an access attempt, determining that the access attempt is associated with the first operator-defined access category value;
receiving system information related to access category barring;
determining whether the access attempt is barred, based on the first operator-defined access category value the access attempt is associated with and based on the system information related to access category barring; and
on a condition that the access attempt is determined to not be barred, initiating a radio resource control (RRC) connection establishment procedure.

12. The system of claim 11 , wherein, in addition to the information indicating that a first operator-defined access category value of the one or more operator-defined access category values is associated with an operating system identifier, the first operator-defined access category value of the one or more operator-defined access category values is associated with an application.

13. The system of claim 11 , wherein the information indicates that a second operator-defined access category value
