Client-Based Multimode Handover in Communication Systems
First Claim
1. A communication system comprising:
- a first communication device being in communication with a second communication device via a communication connectivity to a first communication network, the first communication device having a first handover module operable to handover communication connectivity from the first communication network to a second communication network; and
the second communication device having a second handover module cooperatively operable with the first handover module to maintain communication between the second communication device and the first communication device while the first handover module operates to handover communication connectivity from the first communication network to the second communication network.

Abstract
A communication system having a first communication device being in communication with a second communication device via a communication connectivity to a first communication network. The first communication device having a first handover module operable to handover communication connectivity from the first communication network to a second communication network. The second communication device having a second handover module cooperatively operable with the first handover module to maintain communication between the second communication device and the first communication device while the first handover module operates to handover communication connectivity from the first communication network to the second communication network.

13. A method of handover comprising:
-
establishing a first communication path between a local communication device and a remote communication device via a first network connection of the local communication device; communicating a first message having an identity information from the local communication device to the remote communication device via the first communication path, wherein the remote communication device confirms receipt of the identity information; forming a second network connection at the local communication device and sending a second message having the identity information via the second network connection to the remote communication device; establishing a second communication path between the local communication device and the remote communication device via the second network connection at the local communication device in response to receiving the second message; and terminating the first communication path. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method for a client-based handover process comprising:
-
establishing a first communication path between a local communication device and a remote communication device via a first network connection of the local communication device; sending, by the local communication device, a first message having an identifying information of the first communication device across the first network connection to the remote communication device; determining, by the local communication device, to form a second communication path between the local communication device and the remote communication device by utilizing a second network connection of the local communication device; sending, by the local communication device, a second message having the identifying information across the second network connection of the local communication device; establishing the second communication path between the local communication device and the remote communication device via the second network connection of the local communication device; and terminating the first communication path.

23. A method for a client-based handover process comprising:
-
establishing a first communication path between a remote communication device and a local communication device via a first network connection of the local communication device; receiving, by the remote communication device, a first message having an identifying information of the first communication device, the first message being received from the first network connection; receiving, by the remote communication device, a second message having the identifying information, the second message being received from the second network connection; establishing a second communication path between the local communication device and the remote communication device utilizing the second network connection of the local communication device; and terminating the first communication path.
