If it is determined in step S620 that the slave device is a device registered as a collective location confirmation service target, the wireless access device transmits collective positioning service information including its own identification information, slave device identification information, received signal strength of the slave device, To the management server (S622). Then, the management server performs a collective positioning service. That is, the management server can transmit the location information of the wireless access device to the master device corresponding to the slave device identification information as the slave device location information.

If it is determined in step S618 that there is no database in which the group location service object information is stored, the wireless access device transmits a group location service object confirmation request signal including its own identification information and slave device identification information to the management server (S624). Then, the management server searches the provided database and determines whether the slave device identification information is registered as a collective location confirmation service target. If it is determined that the device is registered as a target of the group location service, the management server performs the group location service.

On the other hand, the location checking service method can be created by a program, and the codes and code segments constituting the program can be easily deduced by a programmer in the field.
