Claim of US Patent No. 9,504,021

1. A method of operating a Long Term Evolution (LTE) evolved NodeB (eNodeB) to control LTE Carrier Aggregation (CA) for LTE
User Equipment (UE), the method comprising:
wirelessly exchanging first data with the LTE UE using the LTE CA to support at least an LTE Quality-of-Service Class Identifier
5 (QCI 5) data bearer for Internet Protocol Multimedia Session (IMS) signaling;

detecting if the LTE UE accepts at least one of an LTE QCI 1 data bearer for conversational voice call services and an LTE
QCI 2 data bearer for conversational video services while the LTE CA and the LTE QCI 5 data bearer are active, and in response,
disabling the LTE CA for the LTE UE; and

wirelessly exchanging second data with the LTE UE over the LTE QCI 5 data bearer and the at least one of the LTE QCI 1 data
bearer and the LTE QCI 2 data bearer without using the LTE CA in response to the disablement.
