摘要

The automatic selection of a mobile unit (12) as a function of the distance from a central station (10) with a radio message transmitter/ receiver (14). The central station has a geographic position calculation unit (18). The mobile station has a relative position calculation (28, 30, 32) responding to a central station input, indicating the geographic position. A delay is introduced (36) following a function of the distance between the taxi and the mobile phone. The mobile selected is that with the fastest response to the central station.
