Exchange of voice and video between two cellular or wireless telephones

Abstract

This invention satisfies a need for exchanging video between two wireless terminals over a new 4G network. It would be impractical to design the service to operate over existing 2G and 3G networks. These older networks exhibit lack of throughput needed for extensive videophone service since they were originally designed for voice service. This invention will employ the new 4G network to allow a terminal to select the proper bandwidth needed to send either voice only or video and voice over the same wireless connection. Use of class of service characters combined with the receiving terminal address sent by the originating terminal will allow the wireless carrier to process the call as a video to video call by accessing a “caller ID” table distinct from the normal voice “caller ID” table. The new originating “caller ID” will be selected from this table and forwarded to the receiving terminal causing it to enter video mode automatically and to use a distinctive ring tone.
