Abstract: Dynamically modifiable call processing logic includes creating a Basic Call State Machine (BCSM) which is an instantiation of a dynamically executable Call Model having one or more initialization files and one or more shared library functions. The Call Model supplies the BCSM with Advanced Intelligent Network (AIN) compliant basic call processing logic as well as other features and configuration instructions. The BCSM is provided with a number of states, each of which corresponds to a point-in-call (PIC). Each PIC includes one or more substates and may include one or more trigger detection point (TDP). Each TDP includes at least one trigger.

Abstract: Apparatus and methods for the lawful intercept of mobile telecommunication are provided. The A Interface at a base station subsystem is bridged with a Y-cable, and a copy of the data on the telecommunications lines are forwarded to a switch. The out-of-band control information such as SS7 signalling information is forwarded to a processor which continuously monitors the mobile identification numbers and/or telephone numbers of called and calling parties and compares the numbers to a database of to-be-tapped numbers. Upon finding a match, the processor causes the switch to provide the copy of the channel on which the call is being carried to a listening device.
