Abstract

When a radio communication device inputs a target place, it receives information of a radio control apparatus at the target place and those on the route from a database or a radio control apparatus. Upon reception of identification information of the radio control apparatus, the radio communication device compares it with the information of the radio control apparatus, and notifies the comparison result, thereby confirming its current position.

Claims

1. A radio communication device communicating via a base station, comprising:

input unit for inputting identification information for specifying a communication device;

determination unit for determining whether or not execution of a guidance function regarding a place of the communication device specified by the identification information has been instructed by user operation;

communication unit for communicating with the communication device specified by the identification information; and

transmission unit for transmitting the identification information to the base station as information for execution of the guidance function if it is determined that the execution of the guidance function has been instructed and for transmitting the identification information to the base station as information for communication with the communication device if it is determined that the execution of the guidance function has not been instructed.

2. The device according to claim 1, wherein the guidance function is a navigation function, which executes navigation to the place of the communication device specified by the identification information.

3. The device according to claim 2, wherein the navigation function executes navigation on the basis of information received from another apparatus.

4. The device according to claim 2, wherein the navigation function executes navigation on the basis of identification information of a radio base station.

5. A control method of a radio communication device comprising input unit for inputting identification information for specifying a communication device communicated via a base station, the method comprising the step of:

determining whether or not execution of a guidance function regarding a place of the communication device specified by the identification information has been instructed by user operation; and

transmitting the identification information to the base station as information for execution of the guidance function if it is determined that the execution of the guidance function has been instructed and transmitting the identification information to the base station as information for communication with the communication device if it is determined that the execution of the guidance function has not been instructed.

6. The method according to claim 5, wherein the guidance function is a navigation function, which executes navigation to the place of the communication device specified by the identification information.

7. The method according to claim 6, wherein the navigation function executes navigation on the basis of information received from another apparatus.

8. The method according to claim 6, wherein the navigation function executes navigation on the basis of identification information of a radio base station.
