Abstract
Disclosed is a method and system for managing carriers on which a wireless communication system serves a UE over an established radio-link-layer connection. As disclosed, a base station serves the UE with carrier aggregation service using (i) a first carrier as a primary carrier for the UE and (ii) a second carrier as a secondary carrier for the UE. While serving the UE, the system determines that the base station should serve the UE with the carrier aggregation service using (i) the first carrier as the secondary carrier and (ii) the second carrier as the primary carrier. In response to the determination and while maintaining the established radio-link-layer connection with the UE, the system causes the base station to serve the UE with the carrier aggregation service using (i) the first carrier as the secondary carrier and (ii) the second carrier as the primary carrier.
