Validation of mobile stations in unlicensed radio access networks
First Claim
1. An access controller in an unlicensed radio access network, the access controller adapted to communicate with the core network portion of a public mobile communication network and connected to a broadband packet-switched network, said access controller being adapted to receive messages from mobile stations communicating via an unlicensed radio interface with access points connected to said broadband packet-switched network, said access controller comprising:
- a screening module for monitoring information received from a mobile station and a connection controller coupled to said screening module for controlling the connection between the mobile station and the access controller, wherein said screening module is adapted to determine whether a mobile station is permitted to connect to said access controller and said connection controller is adapted to terminate a connection with the mobile station if the screening module determines that the mobile station is not permitted to connect to the access controller.

Abstract
An unlicensed-radio access network includes an access controller (303) adapted to communicate with the core network portion of a public mobile communication network (20) and connected to a broadband packet-switched network (302). The access controller receives messages from mobile stations via the broadband packet-switched network. The access controller comprises a screening module (3031-3034) for monitoring information received from a mobile station and a connection controller (3035) coupled to the screening module for controlling the connection between the mobile station and the access controller. The screening module is adapted to determine whether a mobile station is permitted to connect to the access controller, and the connection controller is adapted to terminate a connection with the mobile station if the screening module determines that the mobile station is not permitted to connect to the access controller.

10. An access controller in an unlicensed radio network the access controller adapted to communicate with the core network portion of a public mobile communication network and connected to a broadband packet-switched network, said access controller being adapted to receive messages from mobile stations communicating via an unlicensed radio interface with access points connected to said broadband packet-switched network, wherein said access controller comprises
a module for extracting at least part of a subscriber identity from information received from said mobile station to obtain a network operator identity for said mobile station, a table containing permitted and/or barred network operator identities coupled to said subscriber identity extractor module, and a connection controller coupled to said module for controlling the connection between the mobile station and the access controller, wherein said subscriber identity extractor module is adapted to compare an extracted network operator identity with network operator identities stored in said table to determine whether said extracted network operator identity is valid and said connection controller is adapted to terminate a connection with the mobile station if the extracted network operator identity is deemed invalid.

11. An access controller in an unlicensed radio network the access controller adapted to communicate with a core network portion of a public mobile communication network and connected to a broadband packet-switched network, said access controller being adapted to receive messages from mobile stations communicating via an unlicensed radio interface with access points connected to said broadband packet-switched network, wherein said access controller comprises
a module for extracting at least part of an equipment identity from information received from said mobile station and a connection controller coupled to said screening module for controlling the connection between the mobile station and the access controller, wherein said equipment identity extracting module is adapted to comparing said extracted equipment identity with a list of permitted and/or barred equipment identities to determine whether said extracted equipment identity is authorised and said connection controller is adapted to terminate a connection with the mobile station if the equipment identity is deemed not authorised.

12. An access controller in an unlicensed radio network the access controller adapted to communicate with a core network portion of a public mobile communication network and connected to a broadband packet-switched network, said access controller being adapted to receive messages from mobile stations communicating via an unlicensed radio interface with access points connected to said broadband packet-switched network, said access controller comprising:
-
a module for monitoring traffic between said mobile station and said access controller and said mobile station and the core network portion; and
a connection controller coupled to said screening module for controlling the connection between the mobile station and the access controller, wherein said monitoring module is adapted to determine whether the pattern or nature of transactions initiated in said mobile station is abnormal and said connection controller is adapted to terminate a connection with the mobile station if the pattern or nature of transactions initiated in said mobile station is deemed abnormal.

13. A method of validating a mobile station in an unlicensed radio access network, wherein the unlicensed radio access network includes an access controller adapted to communicate with the core network portion of a public mobile communication network and connected to a broadband packet-switched network, said access controller being adapted to receive messages from mobile stations communicating via an unlicensed radio interface with access points connected to said broadband packet-switched network, said method comprising the steps of:
-
monitoring information received from a mobile station to determine whether a mobile station is permitted to connect to said access controller, and terminating a connection with the mobile station if it is determined the mobile station is not permitted to connect to the access controller.
