Abstract
A method and apparatus is disclosed for providing continuation of a communication call as a user moves from the coverage area of one communication network to the coverage area of another communication network having different access media and different applications. A voice, data, video or multimedia call involving multiple end-points which may be located on different networks may be placed on hold pursuant to a pause request made by a user of one of the end-points. The networks include processors programmed to interrupt and recognize specified signals, such as a pause request signal, and to respond by providing reconnection identification information. The user making a pause request may generate a reconnection request in a different network to continue the paused call on the new network by using a calling device that is compatible with the access media and applications provided by the new network. Each network has the capability of communicating with processors associated with other networks to establish a new route for the call so that once a reconnection request is received, the call may be resumed.
