Abstract
A vehicle user can request emergency or roadside assistance from a response center by activating a button in the vehicle. The global positioning system is used to continuously store the vehicle location. A cellular telephone network is used to contact a response center and transfer a data string via modem containing information to assist the response center in acting on the request. The response center sends a termination tone to the vehicle upon satisfactory completion of the request. If the vehicle loses contact with the response center prior to receiving the termination tone, it attempts to reestablish communication with the response center.
