Wireless local communication network, access control method for a wireless local communication network and devices suitable therefor
First Claim
1. A wireless local communication network, comprising:
- at least one wireless communication terminal, at least one access point unit with a transceiver for communication with the wireless communication terminal via an air interface, an access control server, connected to the access point unit, with an access control module for checking the access authorization of the wireless communication terminal, an access control module for checking the access authorization of the wireless communication terminal, a request module, in the wireless communication terminal, for transmission of a prepaid value code via the air interface to the access point unit, a value code database, a validation module, in the access control module, for validation of the received value code in the value code database, a clearance module, in the access control module, for clearance of access to access-controlled communication network modules for the wireless communication terminal, and a cancellation module, in the access control module, for cancellation of the received validated value code in the value code database, whereby the access point unit comprises a communication module for transmission to the access control server of the prepaid value code and of an operator identification.

Abstract
In a wireless local communication network, a so-called Wireless Local Area Network (WLAN) a prepaid value code is transmitted from a wireless communication terminal via an air interface to an access point unit of the wireless local communication network, a so-called access point. The validity of the received value code is checked in a value code database by a centralized access control server. If applicable, the access to the wireless local communication network and to communication networks connected thereto, for example the Internet, is cleared for the wireless communication terminal. After the clearance, a monetary amount is credited to the operator of the access point unit and the validated value code is cancelled in the value code database.

11. A computer program product comprising:
- a computer-readable medium with computer program code means, contained therein, for control of a processor of an access control server connectible to a wireless local communication network in such a way that the access control server validates in a value code database a prepaid value code received from a wireless communication terminal over an air interface of the wireless local communication network, wherein the access control server clears access to the wireless local communication network for the wireless communication terminal and wherein the access control server cancels in the value code database the received validated value code, and
wherein the computer program product comprises further computer program code means which control the processor of the access control server in such a way that the access control server credits a monetary amount to an operator of an access point unit of the wireless local communication network, which operator is identified through an operator identification which has been received from the access point unit which has transmitted the prepaid value code to the access control server. - View Dependent Claims (12)
