A mobile telecommunications system includes a plurality of base stations each being communicatable with a mobile station by radio. A telecommunications network accommodates the plurality of base stations for switching communications to the plurality of base stations. A system center is connected to the telecommunications network for selecting an optimum route on the basis of instantaneous traffic conditions. Any of the base stations sends to the mobile station base station data representative of the base station. When the mobile station sends a guidance request for requesting route guidance data, the telecommunications network reports the guidance request to the system center. The system center selects, in response to the guidance request, an optimum route matching instantaneous traffic conditions and transmits optimum route data representative of the optimum route to the mobile station over the telecommunications network.

Route guidance system for provding a mobile station with optimum route

A mobile telecommuncations system has multiple base stations each defining a miniature service zone and capable of communicating with mobile stations present in the service zone over a radio link. Geographically associated ones of the base stations are spaced apart from each other by an area which is not responsive to electromagnetic waves on the radio links, whereby the base stations are allowed to share the same frequency for the electromagnetic waves. The base stations are interconnected to an on-road vehicle telecommunications network which switches communications to the base stations.
