  • Route guidance system for provding a mobile station with optimum route data in response to a guidance request together with base station data indicative of an identification of a base station
    Patent number: 5187810
    Abstract: 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.
