Abstract

Concepts and technologies disclosed herein are directed to service aware carrier aggregation. According to one aspect disclosed herein, an eNodeB (“eNB”) can learn, via a primary serving cell (“PSC”), that a user equipment (“UE”) has a capability to utilize a carrier aggregation feature. The eNB can receive policy information and service information, and can learn, via the PSC, a service requested by the UE. The eNB can determine, based at least in part upon the policy information, the service information, and the service, whether to implement the carrier aggregation feature to provide the service to the UE. When the eNB determines that the carrier aggregation feature is to be implemented, the eNB can inform the UE to reconfigure a radio resource control (“RRC”) configuration to include the PSC and a secondary serving cell (“SSC”). The eNB can allocate physical media resources for the service from the PSC and the SSC.

First claim

We claim:

1. An eNodeB that provides a primary serving cell and a secondary serving cell, the eNodeB comprising:
a carrier aggregation service aware scheduler;
a primary serving cell agent;
a processor; and
a memory component storing instructions that, when executed by the processor cause the processor to perform operations comprising
establishing, with a user equipment, a radio resource control connection via a primary component carrier corresponding to the primary serving cell,
generating and sending a capability inquiry to the user equipment,
in response to the capability inquiry, receiving, by the primary serving cell agent, from the user equipment, capability information indicating that the user equipment is capable of implementing a carrier aggregation feature,
receiving, by the carrier aggregation service aware scheduler, policy information from the primary serving cell agent,
receiving, by the carrier aggregation service aware scheduler, service information from the primary serving cell agent,
learning, by the carrier aggregation service aware scheduler, a service requested by the user equipment,
determining, based at least in part upon the policy information, the service information, and the service requested by the user equipment, whether to implement the carrier aggregation feature to provide the service to the user equipment,
when the eNodeB determines that the carrier aggregation feature is to be implemented, requesting, by the carrier aggregation service aware scheduler, the user equipment to reconfigure the radio resource control connection to add a secondary component carrier corresponding to the secondary serving cell, and
allocating, by the carrier aggregation service aware scheduler, physical media resources for the service from both the primary serving cell and the secondary serving cell.

2. The eNodeB of claim 1 , wherein the policy information comprises a rule that specifies a condition under which the user equipment should utilize the carrier aggregation feature on a service-specific basis.

3. The eNodeB of claim 1 , wherein the service information specifies a plurality of services available to the user equipment.

4. The eNodeB of claim 1 , wherein the operations further comprise, when the eNodeB determines that the carrier aggregation feature is not to be implemented, maintaining the radio resource control connection.

5. The eNodeB of claim 1 , wherein allocating physical media resources for the service from both the primary serving cell and the secondary serving cell is based upon a bandwidth requirement of the service.

6. The eNodeB of claim 5 , wherein allocating physical media resources for the service from both the primary serving cell and the secondary serving cell is further based upon radio link control buffer status.

7. The eNodeB of claim 1 , wherein requesting, by the carrier aggregation service aware scheduler, the user equipment to reconfigure the radio resource control connection comprises requesting, by the carrier aggregation service aware scheduler, the user equipment to reconfigure the radio resource control connection to add a further secondary serving cell.

8. A method comprising:
establishing, by an eNodeB that provides a primary serving cell and a secondary serving cell, with a user equipment, a radio resource control connection via a primary component carrier corresponding to the primary serving cell;
generating and sending, by the eNodeB, a capability inquiry to the user equipment;
in response to the capability inquiry, receiving, by a primary serving cell agent, from the user equipment, by the eNodeB, capability information indicating that the user equipment is capable of implementing a carrier aggregation feature;
receiving, by a carrier aggregation service aware scheduler of the eNodeB, policy information from the primary serving cell agent;
receiving, by the carrier aggregation service aware scheduler of the eNodeB, service information from the primary serving cell agent;
learning, by the carrier aggregation service aware scheduler of the eNodeB, a service requested by the user equipment;
determining, by the eNodeB, based at least in part upon the policy information, the service information, and the service requested by the user equipment, whether to implement the carrier aggregation feature to provide the service to the user equipment;
when the eNodeB determines that the carrier aggregation feature is to be implemented, requesting, by the carrier aggregation service aware scheduler of the eNodeB, the user equipment to reconfigure the radio resource control connection to add a secondary component carrier corresponding to the secondary serving cell; and
allocating, by the carrier aggregation service aware scheduler of the eNodeB, physical media resources for the service from both the primary serving cell and the secondary serving cell.

9. The method of claim 8 , wherein the policy information comprises a rule that specifies a condition under which the user equipment should utilize the carrier aggregation feature on a service-specific basis.

10. The method of claim 8 , wherein the service information specifies a plurality of services available to the user equipment.

11. The method of claim 8 , further comprising, when the eNodeB determines that the carrier aggregation feature is not to be implemented, maintaining the radio resource control connection.

12. The method of claim 8 , wherein allocating physical media resources for the service from both the primary serving cell and the secondary serving cell is based upon a bandwidth requirement of the service.

13. The method of claim 12 , wherein allocating physical media resources for the service from both the primary serving cell and the secondary serving cell is further based upon radio link control buffer status.

14. The method of claim 8 , wherein requesting, by the carrier aggregation service aware scheduler of the eNodeB, the user equipment to reconfigure the radio resource control connection comprises requesting, by the carrier aggregation service aware scheduler of the eNodeB, the user equipment to reconfigure the radio resource control connection to add a further secondary serving cell.

15. A computer-readable storage medium comprising computer-executable instructions that, when executed by a processor of an eNodeB, which provides a primary serving cell and a secondary serving cell, cause the eNodeB to perform operations comprising:
establishing, with a user equipment, a radio resource control connection via a primary component carrier corresponding to the primary serving cell;
generating and sending a capability inquiry to the user equipment;
in response to the capability inquiry, receiving, by a primary serving cell agent, from the user equipment, capability information indicating that the user equipment is capable of implementing a carrier aggregation feature;
receiving, by a carrier aggregation service aware scheduler, policy information from the primary serving cell agent;
receiving, by the carrier aggregation service aware scheduler, service information from the primary serving cell agent;
learning, by the carrier aggregation service aware scheduler, a service requested by the user equipment;
determining, based at least in part, upon the policy information, the service information, and the service requested by the user equipment, whether to implement the carrier aggregation feature to provide the service to the user equipment;
when the eNodeB determines that the carrier aggregation feature is to be implemented, requesting, by the carrier aggregation service aware scheduler, the
