Abstract
Implemented on a vehicle, a communication system used to notify a passenger of an incoming telephone call. The communication system includes a telephony system assigned to one or more passenger(s) of the vehicle. The telephony system includes a passenger control unit ("PCU") and a passenger control handset ("PCH") coupled to the PCH, both having processing capability. Either of these units may process telephone information transferred to the telephony system, and in response of detecting a telephone call command, perform a call notification scheme to indicate to the passenger(s) that an incoming telephone call has arrived.
