Video-telephony and inter-phony signal transmitting and receiving process for e.g. cellular telephone, involves using local wireless communication protocol to establish wireless connection between terminal and communication system

摘要

The process involves using a local wireless communication protocol e.g. Bluetooth communication protocol, that establishes a local wireless connection (2) between a mobile communication terminal (3) e.g. cellular telephone, and a video-telephony and/or inter-phony communication system (1). The system (1) comprises a central device (12) and an external device (11). Independent claims are also included for the following: (A) a mobile communication terminal implementing a video-telephony and inter-phony signal transmitting and receiving process (B) a video-telephony and/ or inter-phony system implementing a video-telephony and inter-phony signal transmitting and receiving process.
