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 hybrid peer-to-peer networking environment comprising:

logging into the peer-to-peer network by a first endpoint;

notifying directly, by the first endpoint, 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;

receiving, at the first endpoint, session parameters associated with the active communication session directly from the second endpoint;

notifying directly, by the first endpoint, the third endpoint that the first endpoint is online; and

re-establishing, by the first endpoint, the active communication session with the third endpoint using the session parameters.
