Abstract

An improved system and method for wireless data transmission across a variety of telecommunications services operating under a variety of standards is disclosed. The system and method operate by separating the call and connection control in mobile access, providing a generic call control mechanism offering uniformity in communications and allowing a separate connection control mechanism to handle the physical and virtual channel connections.

Claims

1. A telecommunications system for connecting a mobile subscriber terminal to a service node, said system comprising:

a Mobile Services Center in radio communication with said mobile subscriber terminal and in wireline communication with said service node;

radio call control means within both said Mobile Services Center and said mobile subscriber terminal, said radio call control means coordinating said radio communication therebetween; and

service call control means within both said Mobile Services Center and said mobile subscriber terminal, said service call control means coordinating said wireline communication with said service node, said service call control means within said Mobile Services Center being connected to said radio call control means therein, and said service call control means within said mobile subscriber terminal being disconnected from said radio call control means.

2. The telecommunications system according to claim 1, further comprising:

wireless network resource handling means, within said Mobile Services Center, for coordinating resources used by said radio call control means and said service call control means.

3. The telecommunications system according to claim 2, wherein said wireless network resource handling means allocates said resources if said radio and wireline communications are accepted.

4. The telecommunications system according to claim 2, wherein said wireless network resource handling means rejects allocation of said resources if said radio or wireline communications are rejected.

5. The telecommunications system according to claim 1, further comprising:

a fixed-side call control means, within said Mobile Services Center and connected to said service call control means therein, for coordinating said wireline communication with said service node.

6. The telecommunications system according to claim 5, wherein said fixed-side call control means coordinates said wireline communication pursuant to a given one of a multiplicity of telecommunications networks attached thereto.

7. The telecommunications system according to claim 1, further comprising:

interworking function means, within said Mobile Services Center, for converting a radio communication from said Mobile subscriber terminal to a given wireline communication mode.

8. The telecommunications system according to claim 7, wherein said interworking function means coordinates said conversion pursuant to a given one of a multiplicity of wireline communication modes.

9. The telecommunications system according to claim 1, further comprising:

an asynchronous transfer mode means for connecting said Mobile Services Center to said service mode.

10. The telecommunications system according to claim 9, wherein said asynchronous transfer mode means is a Broadband Integrated Services Digital Network.

11. The telecommunications system according to claim 1, wherein said service node is a gateway to another telecommunications system.

12. The telecommunications system according to claim 11, wherein said service node is a gateway between a Transmission Control Protocol/Internet Protocol network.

13. In a telecommunications system having a mobile subserver terminal in communication with a Mobile Services Center (MSC), said Mobile Services Center being in wireline communication with a service node, a method for connecting said mobile subscriber terminal (MT) to said service node, said method comprising the steps of:

receiving, within an MSC service call controller within said mobile subscriber terminal, a call setup request from an MT service call controller within said mobile subscriber terminal to said service node, said call setup request containing therein interface connection parameters;

forwarding, from said MSC service call controller, said interface connection parameters of said call setup request to an MSC wireless call controller within said Mobile Services Center;

establishing a resources link between said mobile subscriber terminal and said service node; and

upon establishment of said resources link, forwarding, from said MSC wireless call controller to an MT wireless call controller within said mobile subscriber terminal, a call setup request reply to said call setup request, thereby establishing a communication link between said mobile subscriber terminal and said service node.

14. The method according to claim 13, wherein, in said step at receiving, said call setup request is a high-level message pursuant to an ISDN protocol.

15. The method according to claim 13, wherein, in said step of establishing the resources link, a resource handler connected to said MSC wireless call controller establishes said resources link.

16. The method according to claim 15, wherein the resource handler converts said interface connection parameters to a plurality of radio access parameters associated with said resources link.

17. The method according to claim 13, wherein, after said step of receiving the call setup request, the MSC service call controller forwards a plurality of service parameters to a fixed-side call controller, said fixed-side call controller establishing said resources link.
