Abstract

A network is provided comprising at least one access point and one access-controlling node whereby the identity of the station can be approved by the access controlling node. The at least one access-controlling node issues at least one Inter-Access Point Protocol message causing the access point with which the station is currently associated to disassociate the given station thereby terminating the access for the given station.

Claims

1. A network comprising at least one access point (AP) and one access controlling node, the access points making use of the Inter-Access Point Protocol (IAPP) for communication, wherein at least one mobile station may associate with the access points, wherein the identity of the mobile station can be approved by the access controlling node, wherein:

the access controlling node monitors whether a given mobile station has access to any of a given subset of access points and monitors an account relating to the given mobile station associated with a given access point of the subset of access points; and

,

if detecting that the account relating to the given mobile station has a balance of zero,

the at least one access-controlling node issues at least one IAPP message causing the access point of the subset with which the mobile station is currently associated to disassociate the given mobile station, thereby terminating access for the given mobile station.

2. The network according to claim 1, wherein the access controlling node is an authentication server connected to the Internet.

3. The network according to claim 2, wherein a second access control node is provided, the second access control node being a gateway node.

4. The network according to claim 2, wherein the access controlling node issues an IAPP ADD-notify message.

5. The network according to claim 2, wherein the access controlling node issues an IAPP MOVE-notify message.

6. The network according to claim 3, wherein the access controlling node issues a Lock out request to the gateway node.

7. An access controlling node for connecting to a group of access points, the access points making use of the Inter-Access Point Protocol (IAPP) for communication and providing access to at least one mobile station, wherein the identity of the mobile station can be approved by the access controlling node, wherein:

the access controlling node monitors whether a given mobile station has access to any of a given subset of access points and monitors an account relating to the given mobile station associated with a given access point of the subset of access points; and

,

if detecting that the account relating to the given mobile station is zero,

the access-controlling node issues at least one IAPP message causing the access point of the subset with which the mobile station is currently associated to disassociate the given mobile station, thereby terminating access for the given mobile station.

8. A method of terminating access for a Wireless Local Area Network (WLAN) mobile station, comprising the steps of:

monitoring whether a given mobile station has access to any of a given subset of access points and monitoring an account relating to the given mobile station associated with a given access point of the subset of access points; and

,

if detecting that the account relating to the given mobile station has a balance of zero,

issuing an Inter-Access Point Protocol (IAPP) message causing the access point of the subset with which the given station is associated to disassociate the given station.
