Wireless LAN system capable of re-transmission under management of a base station device to a destination mobile terminal device
First Claim
1. A wireless LAN system having a plurality of mobile terminal devices and a plurality of base station devices each capable of managing said mobile terminal devices, and a wired LAN connecting the base station devices for communicating with each other, wherein the base station devices register identifications of all presently managed mobile terminal devices in a first database, and each mobile terminal device registers an identification of a base station device by which said mobile terminal device is presently managed in a second database, a wireless communication takes place between a base station device and a mobile terminal respectively specified by the respectively registered identifications, and communication between mobile terminal devices managed by base station devices takes place through the base station devices and the wired LAN, including:
- the mobile terminal devices comprising means for issuing a registration request through a wireless communication; and
each base station device comprising a third database for presetting identifications of the mobile terminal devices allowed to subscribe to the system, means for deciding to accept the registration request based on whether or not identification of the request-issuing mobile terminal device is registered in the third database, means for registering acceptance of the request-issuing mobile terminal device into the first database, and means for informing the request-issuing mobile terminal device that the request is successfully accepted.

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.

18. A base station device capable of performing a bidirectional wireless communication with mobile terminal devices through a wireless network and performing a communication with another base station device through a wired LAN, and having a mobile terminal managing database for holding identification of currently managed mobile terminal devices, comprising
a mobile terminal confirming database for pre-setting identification of mobile terminal devices which are allowed as subscribers of said wireless network; -
means for refusing a request from a mobile terminal for which identification is not found in the mobile terminal confirming database; and means for registering identification of a mobile terminal device in the mobile terminal managing database when identification of the mobile terminal device is found in said mobile terminal confirming database.

19. A wireless network control method for a wireless communication network comprising a plurality of mobile terminal devices including a method for restricting the number of mobile terminal devices which are managed by a base station device in said network;
- the base station device having a first database which contains identifications of all mobile terminal devices which are allowed as subscribers to said network and a second database which holds identifications of all presently-managed mobile terminal devices, including the steps of;
pre-setting in said first database identifications of the mobile terminal devices which are allowed as subscribers of the base station device in the wireless network; receiving, by the base station device, a registration request through a wireless communication from one of the mobile terminal devices; deciding, by the base station device, whether to accept the wireless registration request based on whether or not identification of the request-issuing mobile terminal device is preset in said first database; registering, by the base station device, acceptance of the request-issuing mobile terminal device into the second database if said identification of the request-issuing mobile terminal device is preset in said first database; and informing the request-issuing mobile terminal device that the request has been successfully accepted. - View Dependent Claims (20, 21)

22. A wireless network control method for controlling a wireless LAN system wherein mobile terminal devices are managed by a base station device in a wireless communication network and the base station device has a mobile terminal managing database which holds identifications of presently managed mobile terminal devices, including the steps of:
-
assigning, with the base station device, a first mobile terminal device a data transmission slot; responsive to the assignment, sending, by the first mobile terminal device, data directly to a second mobile terminal device in a wireless communication; receiving the data, by the base station device, while the data is being sent directly between the first and second mobile terminal devices in the wireless communication; detecting, by the base station device, receivability of the second mobile terminal device; and re-transmitting, by the base station device, the received data to the second mobile terminal device if the second mobile terminal has communication failure and the second mobile terminal device is registered in the mobile terminal managing database. - View Dependent Claims (23, 24, 25, 26)
