Abstract
Abstract A mobile telecommunications system includes aplurality of base stations (10) each being communicatable with a mobile station (16) by radio, and a telecommunications network (22) accommodating the plurality of base stations (10) for switching communications to the plurality of base stations (10). A system center (26) is connected to said telecommunications network (22) for selecting an optimum route on the basis of instantaneous traffic conditions. Any of the base stations (10) transmits to the mobile station (16) base station data representative of the base station (10). When the mobile station (16) sends a guidance request for requesting route guidance data, the telecommunications network (22) reports the guidance request to the system center (26). The system center (26) 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 (16) over the telecommunications network (22).
