Abstract

The AIN model as defined by the ITU-T in their Q.1200 series of specifications uses event trigger mechanism via detection points in the Basic Call State Model (BCSM) to communicate with and sup- port advanced services in the network. However the Call Control Agent Function (CCAF) in the termi- nal is designed to support services based on the fixed BCSM in the Network and no mechanism exists to modify its behavior. The CCAF is normal- ly customized for the desired advanced service. This limits the terminal capabilities.

INTELLIGENT CALL CONTROL AGENT

1 PROBLEM STATEMENT 2 SOLUTION

The AIN model as defined by the ITU-T in their
4.1200 series of specifications uses event trigger mechanism via detection points in the Basic Call State Model (BCSM) to communicate with and sup- port advanced services in the network. However the Call Control Agent Function (CCAF) in the termi- nal is designed to support services based on the fixed BCSM in the Network and no mechanism exists to modify its behavior. The CCAF is normal- ly customized for the desired advanced service. This limits the terminal capabilities.

  The limitation can be overcome by having a Basic Call State Model in the CCAF in the terminal. The Call Model in the CCAF would interact with the BCSM in the network, provide detection points to its user thereby providing an easy and generic mechanism to alter the behavior of the agent and offer many more combinations of advanced ser- vices. Figure 1 shows the Call Control Agent Call Model for the normal behavior.
