Abstract

An Application Server Autonomous Access (ASAA) system for providing autonomous access to a wireless infrastructure by devices employing different types of access technology. The system includes a server, having an associated data storage device, for storing at least one policy, and a plurality of subnetworks, coupled to server, for providing access to the server. The plurality of subnetworks employ at least two different types of access technology. A plurality of wireless transmit/receive units (WTRUs) are wirelessly coupled to at least one of the subnetworks. The server monitors the wireless coupling and, depending upon the at least one policy, switches the WTRUs between different ones of the subnetworks.

Claims

1. A method of providing wireless telecommunication services, implemented in at least one network node, the method comprising:

maintaining a mobility policy and a list of a plurality of access networks which are available for the wireless transmit/receive unit (WTRU) to connect, wherein the plurality of access networks comprise a first access network including a first access technology and a second access network including a second access technology that is different from the first access technology;

communicating with the WTRU via the first access network using Internet Protocol (IP);

obtaining a permanent identity for the WTRU;

sending mobility-related information regarding the first and the second access network to the WTRU based on the mobility policy and the permanent identity; and

communicating with the WTRU via the second access network using IP in response to a transition of the WTRU from the first access network to the second access network.

2. The method of claim 1 further comprising communicating through a public data network (PDN).

3. The method of claim 1 further comprising receiving location information regarding the WTRU from a registration procedure.

4. The method of claim 1 wherein the mobility policy is based on location information.

5. The method of claim 1 wherein the mobility policy is based on access network profile information.

6. The method of claim 1 wherein the mobility policy is based on network capability information.

7. The method of claim 1 wherein the mobility-related information is provided to the WTRU via a push service.

8. The method of claim 1 wherein the first access network includes one of a wireless local area network (WLAN), a wireless private area network (WPAN), a universal mobile telecommunications system (UMTS) of a terrestrial radio access network (UTRAN), a code division multiple access (CDMA) 2000 network, a small office/home office (SOHO) network, a Bluetooth network, an IEEE 802.11 network, an IEEE 802.15 network or a ZigBee network.

9. The method of claim 1 wherein the second access network includes one of a wireless local area network (WLAN), a wireless private area network (WPAN), a universal mobile telecommunications system (UMTS) of a terrestrial radio access network (UTRAN), a code division multiple access (CDMA) 2000 network, a small office/home office (SOHO) network, a Bluetooth network, an IEEE 802.11 network, an IEEE 802.15 network or a ZigBee network.

10. A method of providing wireless telecommunication services, implemented in at least one network node, the method comprising:

maintaining a mobility policy and a list of a plurality of access networks which are available for the wireless transmit/receive unit (WTRU) to connect, wherein at least two of the plurality of access networks are based on different access technologies;

communicating with the WTRU via a first access network using Internet Protocol (IP);

obtaining a permanent identity for the WTRU;

sending mobility-related information regarding the first and the second access network to the WTRU based on the mobility policy and the permanent identity; and

communicating with the WTRU via a second access network using IP in response to a transition of the WTRU from the first access network to the second access network;

wherein at least one of the first access network and the second access network is included in the list of the plurality of access networks.

11. The method of claim 10 further comprising communicating through a public data network (PDN).

12. The method of claim 10 further comprising receiving location information regarding the WTRU from a registration procedure.

13. The method of claim 10 wherein the mobility policy is based on location information.

14. The method of claim 10 wherein the mobility policy is based on access network profile information.

15. The method of claim 10 wherein the mobility policy is based on network capability information.

16. The method of claim 10 wherein the mobility-related information is provided to the WTRU via a push service.

17. The method of claim 10 wherein the first access network includes one of a wireless local area network (WLAN), a wireless private area network (WPAN), a universal mobile telecommunications system (UMTS) of a terrestrial radio access network (UTRAN), a code division multiple access (CDMA) 2000 network, a small office/home office (SOHO) network, a Bluetooth network, an IEEE 802.11 network, an IEEE 802.15 network or a ZigBee network.

18. The method of claim 10 wherein the second access network includes one of a wireless local area network (WLAN), a wireless private area network (WPAN), a universal mobile telecommunications system (UMTS) of a terrestrial radio access network (UTRAN), a code division multiple access (CDMA) 2000 network, a small office/home office (SOHO) network, a Bluetooth network, an IEEE 802.11 network, an IEEE 802.15 network or a ZigBee network.
