System and method for controlling handover
First Claim
1. A method of controlling handover of a mobile station conducting a communications session in a mobile communications network, the network including a plurality of radio access domains, each having a radio access technology associated therewith, the method comprising:
- receiving a trigger from the mobile station indicating a requirement for handover, wherein said requirement specifies a change in radio access technology requirements;
testing at least one possible handover meeting said requirement for handover against network policy; and
controlling handover in accordance with said requirement for handover and said network policy;
wherein said requirement for handover is an application requirement, and wherein said application requirement is unrelated to radio signaling quality.

11. An apparatus for a mobile communications network, the mobile communications network comprising a plurality of radio access domains, each having a radio access technology associated therewith, the apparatus configured to communicate with a plurality of radio access domains, the apparatus further configured to:
-
receive a trigger from the mobile station indicating a requirement for handover, wherein said requirement specifies a change in radio access technology requirements; test at least one possible handover meeting said requirement for handover against said network policy; and control handover in accordance with said requirement for handover and said network policy; wherein said requirement for handover is an application requirement, and wherein said application requirement is unrelated to radio signaling quality.

12. A computer-readable medium comprising a program for performing a method of controlling handover of a mobile station conducting a communications session in a mobile communications network, the network including a plurality of radio address domains, each having a radio access technology associated therewith, the method comprising:
-
receiving a trigger from the mobile station indicating a requirement for handover, wherein said requirement specifies a change in radio access technology requirements; testing at least one possible handover meeting said requirement for handover against network policy; and controlling handover in accordance with said requirement for handover and said network policy; wherein said requirement for handover is an application requirement, and wherein said application requirement is unrelated to radio signaling quality.

13. A method of conducting handover in a mobile communications network including a plurality of radio access domains, wherein each radio access domain has a radio access technology associated therewith, the method comprising, in response to receipt from a mobile station of a requirement for handover specifying a change in radio technology requirements, conducting handover in accordance with a handover algorithm, said algorithm taking network policy data and said change in radio access technology requirements as input during a handover decision process. wherein said requirement for handover is an application requirement, and wherein said application requirement is unrelated to radio signaling quality.
