Abstract
A method and apparatus for intercepting calls within a wireless communications system. In particular, the present invention provides a call intercept component and a number of control points. Each of the control points is associated with a layer or component within the wireless communications system that handles messages associated with a mobile station within the wireless communications system. Each control point monitors messages received at the component or layer associated with the control point. The messages are examined to determine whether the message is appropriate for interception. If the message is appropriate for interception, the message is then sent the call interception layer. In turn, the call interception layer formats data from the message and routes it to a destination.
