Abstract

Method and apparatus for providing a solution to the handoff problem includes negotiation of new media codes (coders/decoders) for utilization in cases where the two devices involved in the handoff are incompatible. Although mobile IP (MIP) is presently utilized to perform handoff procedures, this technique lacks a trigger mechanism to initiate handoff between two different devices which communicate with two different networks or one common network. In addition, MIP does not address the issue of compatibilities between media types, codes and supported bit rate. The handoff utilizes a session protocol (SIP) message for handoff.

Claims

1. A communication device comprising:

circuitry configured to;

generate a first message associated with an email address of a user of a remote device; and

transmit the first message over a communication network to establish a communication session with the remote device.

2. The communication device of claim 1 wherein the first message is a session initiation protocol (SIP) message.

3. The communication device of claim 2 wherein the first message is a SIP INVITE message.

4. The communication device of claim 1 wherein the circuitry is configured to receive a second message in response to the first message.

5. The communication device of claim 4 wherein the second message is a SIP message.

6. The communication device of claim 1 wherein the first message further indicates an Internet Protocol (IP) address or a telephone number.

7. The communication device of claim 1 wherein the communication session comprises video.

8. The communication device of claim 1 wherein the communication device is a mobile UE.

9. The communication device of claim 1 wherein the first message is sent to a service server.

10. A method for use in a communication device for establishing a communication session with a remote device, the method comprising:

generating a first message associated with an email address of a user of the remote device; and

transmitting the first message over a communication network to establish a communication session with the remote device.

11. The method of claim 10 wherein the first message is a session initiation protocol (SIP) message.

12. The method of claim 11 wherein the first message is a SIP INVITE message.

13. The method of claim 10 further comprising receiving a second message in response to the first message.

14. The method of claim 13 wherein the second message is a SIP message.

15. The method of claim 10 wherein the first message further indicates an Internet Protocol (IP) address or a telephone number.

16. The method of claim 10 wherein the communication session comprises video.

17. The method of claim 10 wherein the communication device is a mobile UE.

18. The method of claim 10 wherein the first message is sent to a service server.
