First Claim
1. A service communication system for mobile vehicles, comprising:
- a cellular telephony interface in individual ones of the mobile vehicles, for establishing telephony events over a cellular network with a base station;
a global positioning system in individual ones of the mobile vehicles for determining global position from transmissions from GPS satellites;
a network of base stations for receiving and broadcasting to the mobile vehicles, and for bridging events between cellular and public switched telephone service (PSTN) protocol;
a network-level switching system connected by first telephony trunks to the base stations and enabled to retrieve GPS position from the telephony events; and
a plurality of communication centers each enabled to respond to service requests connected to the network-level routing system by second telephony trunks;
wherein the network-level switching system has a table associating GPS positions with individual ones of a plurality of specific geographic regions and individual ones of the plurality of communication centers also with individual ones of the plurality of geographic regions and routs the telephony events to communication centers within the geographic region according to the associations, and wherein individual ones of the communication centers each comprise a telephone switching apparatus connected by a computer telephony integration (CTI) link to a CTI processor for monitoring and controlling the connected telephone switching apparatus, and the network switching system comprises a network-level CTI processor connected to a network-level switch, and wherein the CTI processors at network and communication center level are interconnected by a data link separate from the second telephony trunks.

Abstract
A service communication system for mobile vehicles has a cellular telephony interface in individual ones of the mobile vehicles, for establishing telephony events over a cellular network with a base station, and a global positioning system in individual ones of the mobile vehicles for determining global position from transmissions from GPS satellites. A network of cellular base stations receives from and broadcasts to the mobile vehicles, lo and bridges events between cellular and public switched telephone service (PSTN) protocol. A unique network-level routing system is connected by first telephony trunks to the base stations and enabled to retrieve GPS position from the telephony events, and is connected by other trunks to a plurality of service centers connected to the network-level routing system, which determines a destination for individual ones of the telephony events among the plurality of service centers according to the retrieved GPS position.
