PROBLEM TO BE SOLVED: To exactly guide the route of mobile object and to exactly transmit map information by storing uncommunicatable or communicatable area information and automatically starting communication when the mobile object in a disable area at the time of communication moves its position calculated from a position detecting means into the communicatable area. SOLUTION: While loading mobile communication equipment 10, the mobile object is traveled according to the prescribed route on the map information provided from a map storage means 3. Corresponding to the map information, an area storage means 4 stores the communication disable area or communication enable area on an optical disk 41 or a magnetic disk 42. It is discriminated whether communication is interrupted during the move of mobile object or not and when the communication is interrupted, while searching the map storage means 3 and the area storage means 4, information is read out for showing whether the communication is enabled at a current position on the map information or not. When it is judged the mobile objects enters the communication enable area on the map information during movement, a communicating means 2 communicates with the destination to communicate again and recovers the communication. |
