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 routing system connected by first telephony trunks to the base stations and enabled to retrieve GPS position from the telephony events; and
a plurality of service centers connected to the network-level routing system by second telephony trunks;
wherein the network-level routing system determines a destination for individual ones of the telephony events among the plurality of service centers according to the retrieved GPS position.

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, 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.
