First Claim
Patent Images
1. A method for communications device operation in a multi-carrier communications system, the method comprising:
- computing a bandwidth requirement;
transmitting a handover request to a server controller, wherein the handover request comprises the bandwidth requirement;
receiving a response responsive to the handover request; and
in response to determining that the handover request was granted, initiating a handover.

9. A method for server controller operation, the method comprising:
-
receiving a handover request from a communications device, the handover request comprising a bandwidth requirement; requesting a carrier allocation from each of one or more potential target controllers, wherein each carrier allocation is based on the bandwidth requirement; receiving the carrier allocation from each of the one or more potential target controllers; selecting a target controller from the one or more potential target controllers, wherein the selecting is based on the carrier allocations from the one or more potential target controllers; and sending a response to the handover request to the communications device, wherein the response comprises the carrier allocation from the selected target controller. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for target controller operation, the method comprising:
-
receiving a carrier allocation request from a serving controller, the carrier allocation request comprising a secondary carrier requirement of a communications device; determining a carrier allocation based on the carrier allocation request; and transmitting the carrier allocation to the serving controller. - View Dependent Claims (18, 19, 20)
