Abstract

A system and method for endpoint handoff in a hybrid peer-to-peer networking environment are provided. In one example, the method includes logging into the peer-to-peer network by a first endpoint. The first endpoint directly notifies a second endpoint that the second endpoint is to transfer an active communication session existing between the second endpoint and a third endpoint from the second endpoint to the first endpoint. The first endpoint receives session parameters associated with the active communication session directly from the second endpoint and directly notifies the third endpoint that the first endpoint is online. The first endpoint then re-establishes the active communication session with the third endpoint using the session parameters.

Claims

1. A method for endpoint handoff in a networking environment comprising:

receiving, by a first endpoint device, session parameters associated with a communication session from a second endpoint device, wherein the session parameters indicate that the communication session exists between the second endpoint device and a third endpoint device, and wherein the session parameters identify at least one type of information being sent between the second and third endpoint devices during the communication session;

sending, by the first endpoint device, information for the communication session to the third endpoint device after receiving the session parameters, wherein the information corresponds to the at least one type of information;

sending, by the first endpoint device, an instruction to the second endpoint device to stop sending the information for the communication session to the third endpoint device;

determining, by the first endpoint device, that the information for the communication session is not being received from the third endpoint device;

communicating, by the first endpoint device, with the third endpoint device to re-establish the communication session, wherein the communicating includes sending, by the first endpoint device, a message to the third endpoint device instructing the third endpoint device to stop sending the information and to not send a termination message; and

receiving, by the first endpoint device, the information for the communication session from the third endpoint device after the communication session is re-established with the third endpoint device.

2. The method of claim 1 further comprising sending a query, from the first endpoint device, to the second endpoint device in order to identify whether the second endpoint device is involved in any communication sessions.

3. The method of claim 2 further comprising receiving, by the first endpoint device, presence information about the second endpoint device in response to logging into a peer-to-peer network, wherein the query message is sent only after receiving the presence information.

4. The method of claim 1 further comprising:

detecting, by the first endpoint device, that the second endpoint device is within a defined range of the first endpoint device; and

sending a query, from the first endpoint device, to the second endpoint device in order to identify whether the second endpoint device is involved in any communication sessions.

5. The method of claim 1 further comprising sending, by the first endpoint device, an instruction to the second endpoint device to terminate the communication session between the second and third endpoint devices without signaling the termination to the third endpoint.

6. The method of claim 1 further comprising sending, by the first endpoint device, an instruction to the second endpoint device to transfer all communication sessions in which the second endpoint device is engaged to the first endpoint device prior to receiving the session parameters.

7. The method of claim 1 further comprising sending, by the first endpoint device, an instruction to the second endpoint device to perform at least one action, wherein the action differs depending on whether the second endpoint device is a cellular telephone or a personal computer.

8. The method of claim 1 wherein the information is audio.

9. The method of claim 1 wherein the information is video.

10. The method of claim 1 wherein the information is data.

11. A method for endpoint handoff in a networking environment comprising:

sending, by a first endpoint device, an instruction to a second endpoint device to transfer all communication sessions in which the second endpoint device is engaged to the first endpoint device;

receiving, by the first endpoint device, session parameters associated with at least one communication session from the second endpoint device, wherein the session parameters indicate that the communication session exists between the second endpoint device and a third endpoint device, and wherein the session parameters identify at least one type of information being sent between the second and third endpoint devices during the communication session;

sending, by the first endpoint device, an instruction to the second endpoint device to stop sending information for the communication session to the third endpoint device without signaling the termination to the third endpoint; and

engaging, by the first endpoint device, in the communication session with the third endpoint device after receiving the session parameters.

12. The method of claim 11 further comprising sending a query, from the first endpoint device, to the second endpoint device in order to identify whether the second endpoint device is involved in any communication sessions.

13. The method of claim 12 further comprising receiving, by the first endpoint device, presence information about the second endpoint device in response to logging into a peer-to-peer network, wherein the query message is sent only after receiving the presence information.

14. The method of claim 11 further comprising:

detecting, by the first endpoint device, that the second endpoint device is within a defined range of the first endpoint device; and

sending a query, from the first endpoint device, to the second endpoint device in order to identify whether the second endpoint device is involved in any communication sessions.

15. A first endpoint device comprising:

a hardware platform; and

an architecture having

a graphical user interface (GUI) configured to provide user access to an endpoint engine;

an operating system configured to provide access to the hardware platform; and

the endpoint engine coupled to the GUI and the operating system, the endpoint engine having a plurality of functional components configured for;

receiving session parameters associated with a communication session from a second endpoint device, wherein the session parameters indicate that the communication session exists between the second endpoint device and a third endpoint device, and wherein the session parameters identify at least one type of information being sent between the second and third endpoint devices during the communication session;

sending information for the communication session to the third endpoint device after receiving the session parameters, wherein the information corresponds to the at least one type of information;

sending an instruction to the second endpoint device to stop sending the information for the communication session to the third endpoint device;

determining that the information for the communication session is not being received from the third endpoint device;

communicating with the third endpoint device to re-establish the communication session, wherein the communicating includes sending, by the first endpoint device, a message to the third endpoint device instructing the third endpoint device to stop sending the information and to not send a termination message; and

receiving the information for the communication session from the third endpoint device after the communication session is re-established with the third endpoint device.

16. The first endpoint device of claim 15 wherein the first endpoint device is a cellular telephone.

17. The first endpoint device of claim 15 wherein the first endpoint device is a personal computer.

18. A first endpoint device comprising:
