Abstract

An access point has a connection to a wide area network, and is configured to allow a device to connect thereto, and includes an Application Programming Interface for allowing a remote application to connect to the access point over the wide area network, and to obtain information relating to the device connected to the access point. In particular, the access point is configured to allow a device to connect thereto over a wireless interface, and to provide bearer translation such that traffic over the wireless interface can be directed over the wide area network. The Application Programming Interface may then allow the application to obtain information relating to a connection status of a wireless device associated with the access point.

Claims

1. An access point, having a connection to a wide area network, and being configured to allow a device to connect thereto, and comprising an Application Programming Interface for allowing a remote application to connect to the access point over the wide area network, and to obtain information relating to the device connected to the access point.

2. An access point as claimed in claim 1, configured to allow a device to connect thereto over a wireless interface.

3. An access point as claimed in claim 2, configured to allow a device to connect thereto over a cellular wireless interface.

4. An access point as claimed in claim 3, configured to transmit and receive traffic from and to the device connected thereto over the wide area network.

10. An access point as claimed in claim 2, wherein the Application Programming Interface allows the remote application to obtain information relating to a set of devices that are permitted to connect to the access point over the wireless interface.

11. An access point as claimed in claim 2, wherein the Application Programming Interface allows the remote application to obtain information relating to network connections of a specific device connected to the access point over the wireless interface.

12. An access point as claimed in claim 1, further configured to allow a device to connect thereto over a local area network, wherein the Application Programming Interface allows the remote application to obtain information relating to the device connected to the access point over the local area network.

13. An access point as claimed in claim 1, having a NAT traversal client, allowing a remote application to obtain the information from the Application Programming Interface.

14. An access point as claimed in claim 1, wherein the application is able to obtain the information from the Application Programming Interface for use while the application is running.

15. An access point as claimed in claim 1, wherein the connection to the wide area network is a connection to a public wide area network.

16. An access point as claimed in claim 15, wherein the public wide area network is the internet.

5. An access point as claimed in 2, wherein the Application Programming Interface allows the remote application to obtain information relating to the device connected to the access point over the wireless interface.

6. An access point as claimed in claim 5, wherein the Application Programming Interface allows the remote application to obtain information as to whether a specific device is attached to or detached from the access point over the wireless interface.

7. An access point as claimed in claim 6, wherein the Application Programming Interface allows the remote application to obtain information as to whether the specific attached device is in idle mode or is in a call or data session over the wireless interface.

8. An access point as claimed in claim 5, wherein the Application Programming Interface allows the remote application to obtain information relating to capabilities of one or more specific device connected to the access point over the wireless interface.

9. An access point as claimed in claim 5, wherein the Application Programming Interface allows the remote application to obtain information relating to a quality of an RF connection between the access point and one or more specific device connected to the access point over the wireless interface.

17. An access point, having a connection to a wide area network, and being configured to allow a device to connect thereto over a wireless interface, and to provide bearer translation such that traffic over the wireless interface can be directed over the wide area network, the access point further comprising an Application Programming Interface for allowing an application to connect to the access point, and to obtain information relating to a connection status of a device associated with the access point.

18. An access point as claimed in claim 17, wherein the information relating to the connection status of the device associated with the access point comprises information as to whether a specific device is attached to or detached from the access point.

19. An access point as claimed in claim 17, wherein the information relating to the connection status of the device associated with the access point comprises information as to whether the device is in idle mode or is in a call or data session.

20. An access point as claimed in claim 17, wherein the information relating to the connection status of the device associated with the access point comprises information relating to an RF connection between the device and the access point.

21. A core network node, connected over a wide area network to a plurality of access points, wherein the core network node comprises a database linking each of a plurality of wireless device identities to at least one respective access point of said plurality of access points, and containing an updatable IP address for each of said access points, and wherein, in response to a query from an application referring to a wireless device identity, the core network node supplies said updatable IP address for the access point linked to the wireless device identity.

22. A core network node as claimed in claim 22 wherein, when a wireless device may be connected to a plurality of said access points, the core network node supplies an IP address of a mobility server, which is in turn able to direct a message from the application to an appropriate one of said plurality of said access points.
