Abstract

A memory stores at least one item of parameter setting information corresponding to respective available environments which are initially set by the user. When the wireless communication function of a portable wireless communication device is made active by powering on, etc., a control section controls a wireless section to allow a search of any wirelessly accessible terminal present within reach of a radio signal. Then the control section infers available environments by comparing the result of the search with surrounding terminal information stored in the memory. Also, the control section reads out control parameter setting information stored in the memory in accordance with the result of the inference and sets the read-out control parameter setting information to the wireless section.

Claims

1. A communication device having a control parameter relating to the communication, the communication device comprising:

a searching unit configured to search any other accessible communication device; and

a control unit configured to compare the result of search by the searching unit and information in association with the result of search and the control parameter, and set the control parameter as a control parameter for use in the communication on the basis of the comparison decision.

2. The communication device according to claim 1, wherein the control unit makes the comparison decision between the number of communication devices contained the information and the number of communication devices searched by the searching unit.

3. The communication device according to claim 1, wherein the control unit updates the information based on the result of the comparison decision between the result of search at the time of starting the communication and the information.

4. The communication device according to claim 3, wherein the control unit calculates the appearance frequency of respective communication devices from the communication devices contained the information and the communication devices searched by the searching unit, and updates the information based on the result of the calculation.

5. A communication device according to claim 1, further comprising display unit which display a result of setting the control parameter by the control unit.

6. A method for setting control parameter of a communication device having a control parameter relating to communication, the method comprising:

searching for any other accessible communication device; and

comparing the result of search and information in association with the result of search and the control parameter, and set the control parameter as a control parameter for use in the communication on the basis of the comparison decision.

7. The method according to claim 6, wherein the comparison decision is made between the number of communication devices contained the information and the number of communication devices searched by the searching step.

8. The method according to claim 6, further comprising updating the information based on the result of the comparison decision between the result of the search at a time of starting the communication and the information.

9. The method according to claim 8, wherein the updating the information based on an appearance frequency of respective communication devices which are calculated from the communication devices contained the information and the communication devices searched by the searching step.

10. The method according to claim 6, further comprising displaying a result of setting the control parameters.

11. A wireless communication device for carrying out wireless communication based on the Bluetooth standard, having various kinds of control parameters for the wireless communication based on the Bluetooth standard including a connectable mode, a security mode, a presence/absence of a dial-up network service, a presence/absence of a LAN access service, a presence/absence of an object push service and a presence/absence of a file transfer service, the wireless communication device comprising:

a searching unit configured to search any other wireless accessible communication devices capable of making wireless communication based on the Bluetooth standard; and

a control unit configured to compare the result of search and information in association with the result of search and the control parameter, and set the control parameter as a control parameter for use in the wireless communication, on the basis of the comparison decision.

12. A method for setting control parameters of a wireless communication device for carrying out wireless communication based on the Bluetooth standard, having various kinds of control parameters for the wireless communication based on the Bluetooth standard including a connectable mode, a security mode, a presence/absence of a dial-up network service, a presence/absence of a LAN access service, a presence/absence of an object push service and a presence/absence of a file transfer service, the method comprising:

searching for any other wireless communication devices; and

comparing the result of the search and information in association with the result of search and the control parameter, and set the control parameters as control parameters for use in the wireless communication on the basis of the comparison decision.
