ABSTRACT:
The present invention is a method and system for transferring calls among communicating devices connected through a public network. The service is offered by a public network to permit a party in a ongoing conversation to transfer a call to another communicating device that may be more convenient to use, such as from a mobile telephone experiencing static to a land-based telephone, or from a home telephone to a mobile phone as a party leaves the home. In a method according to the invention, the network first establishes a connection between two communicating parties. The network then receives from one of the parties a request to transfer the call to another communications device. The network then transfers the call. The invention may be entirely network-based, in which case there may be a database of transferee devices stored on the network. Alternatively, the invention may be hybrid network-based and premises equipment-based, in which case the database of transferee devices may be stored in the premises equipment.
