Abstract: A communication system has a cellular telephony interface in individual ones of two or more mobile vehicles, a position determination system in individual ones of the mobile vehicles, a network of cellular base stations coupled to the mobile vehicles, individual base stations coupled to one or both of a packet-switched or a line-switched telephony system, a router coupled to the base stations and enabled to retrieve GPS position from the telephony events, and a plurality of service centers coupled to one or both of the telephony systems. Telephony events from individual ones of the mobile vehicles are routed according to position reported by the position determination system.

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.
