ABSTRACT:
A wireless network is provided for restricting the number of mobile terminal devices which are managed by the base station device for wireless communication with one another. The base station device has a mobile terminal confirming database for registering mobile terminal devices allowed to be subscribers to the wireless network, and a mobile terminal managing database for registering presently-managed mobile terminal devices. The wireless transfer request from one of the mobile terminal devices is tested to determine whether the request-issuing mobile terminal device is one of the subscribers. If the request is accepted, then the identification of the request-issuing mobile terminal device is registered into the managing database.
