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.
Claims17
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.
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.
