Abstract

A network architecture uses an Application Server Autonomous Access (ASAA) server which allows paging and call routing across different types of wireless and wireline access networks. The ASAA server provides connectivity between an external voice or data network and a wireless transmit/receive unit (WTRU). The external voice or data network may be a public switched telephone network (PSTN) or a public data network (PDN), so that the connectivity between the external network and the WTRU is provided through the access networks using data from the ASAA server.

Claims

1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

the WTRU receiving a first message from a server via an access network; and

the WTRU sending a second message to the server via the access network, wherein the second message is responsive to the first message, and the second message indicates an identity of the access network through which the WTRU sends the second message.

2. The method of claim 1, wherein the first message is a paging request message, and the second message is a paging response message.

3. The method of claim 1, further comprising:

the WTRU receiving a service via the access network in response to sending the second message.

4. The method of claim 3, wherein the receiving the service includes receiving data from a public switched telephone network (PSTN) or a public data network (PDN).

5. The method of claim 1, further comprising:

the WTRU registering with the server via a second access network,

wherein the access network is based on a first access technology, the second access network is based on a second access technology, and the first access technology and the second access technology are different.

6. The method of claim 1, wherein the receiving the first message and the sending the second message are performed using Internet Protocol (IP).

7. The method of claim 1, wherein the server is an Application Server Autonomous Access (ASAA) server.

8. A wireless transmit/receive unit (WTRU), the WTRU comprising:

circuitry configured to receive a first message from a server via an access network; and

circuitry configured to send a second message to the server via the access network, wherein the second message is responsive to the first message, and the second message indicates an identity of the access network through which the WTRU sends the second message.

9. The WTRU of claim 8, wherein the first message is a paging request message, and the second message is a paging response message.

10. The WTRU of claim 8, further comprising:

circuitry configured to receive a service via the access network in response to sending the second message.

11. The WTRU of claim 10, wherein the circuitry configured to receive the service is configured to receive the service by receiving data from a public switched telephone network (PSTN) or a public data network (PDN).

12. The WTRU of claim 8, further comprising:

circuitry configured to register the WTRU with the server via a second access network, wherein the access network is based on a first access technology, the second access network is based on a second access technology, and the first access technology and the second access technology are different.

13. The WTRU of claim 8, wherein:

the circuitry configured to receive the first message is configured to receive the first message using Internet Protocol (IP); and

the circuitry configured to send the first message is configured to send the first message using IP.

14. The WTRU of claim 8, wherein the server is an Application Server Autonomous Access (ASAA) server.

15. A method of providing services to a wireless transmit/receive unit (WTRU), the method comprising:

sending a first message to the WTRU via a plurality of radio access networks;

receiving a second message from the WTRU via one of the radio access networks of the plurality of radio access networks, the second message indicating an identity of the one radio access network through which the WTRU sends the second message; and

routing a service to the WTRU via the one radio access network.

16. The method of claim 15, wherein the first message is a paging request message, and the second message is a paging response message.

17. The method of claim 15, wherein the sending the first message is performed in response to an incoming call to the WTRU;

and

wherein the routing the service includes routing the incoming call.

18. The method of claim 15, wherein the sending the first message is performed in response to a request for communications with the WTRU.

19. The method of claim 18, wherein the request for communications is received from a public switched telephone network (PSTN) or a public data network (PDN).

20. The method of claim 15, wherein the sending the first message and receiving the second message is performed using Internet Protocol (IP).
