    摘要: A system and method for extending the cellular range of communications using a vehicle telematics unit. The system includes the vehicle telematics unit which is connected with other vehicle hardware and includes wireless cellular capability for communicating from the vehicle to a call center or other facilities via a wireless communication system. The method carried out by the system includes identifying a cellular base station in wireless communication with a vehicle telematics unit; attempting an emergency call via the identified cellular base station using the vehicle telematics unit; determining that a forward link portion of a cellular signal between the vehicle telematics unit and the identified cellular base station lacks sufficient strength to place the attempted emergency call; and transmitting emergency communications via the identified cellular base station using a reverse link portion of the cellular signal based on the determination.

    摘要: A system and method of extending the range of a vehicle telematics unit includes determining that a vehicle telematics unit is outside of a geographic range beyond which time division multiple access (TDMA) transmissions sent from the vehicle telematics unit to a base station arrive at the base station after a time slot allocated to the vehicle telematics unit in a time frame has passed; calculating a time delay that causes the TDMA transmissions to arrive at the base station in the allocated time slot of a subsequent time frame; and sending TDMA transmissions from the vehicle telematics unit at a time determined using the time delay.
