System and method for controlling a call processing system
First Claim
1. A communication system to handle a plurality of calls comprising:
- a plurality of call processors that process signaling messages for the calls, and in response, transfer control messages for the calls and transfer data messages for the calls;
a plurality of interworking units that receive the control messages and user communications for the calls and interwork the user communications between a first communication format and a second communication format in response to the control messages; and
a control system that receives and processes the data messages for the calls to maintain an active call database having call data for active ones of the calls, wherein the control system receives a query, and in response, processes the active call database to identify one of the active calls that satisfies the query.

Abstract
A communication system that comprises call processors, interworking units, and a control system handles a plurality of calls. The call processors process signaling messages for the calls, and in response, transfer control messages for the calls and transfer data messages for the calls. The interworking units receive the control messages and user communications for the calls and interwork the user communications between a first communication format and a second communication format in response to the control messages. The control system receives and processes the data messages for the calls to maintain an active call database having call data for active ones of the calls. The control system receives a query, and in response, processes the active call database to identify one of the active calls that satisfies the query.

11. A method of operating a communication system to handle a plurality of calls, the method comprising:
-
in a plurality of call processors, processing signaling messages for the calls, and in response, transferring control messages for the calls and transferring data messages for the calls; in a plurality of interworking units, receiving the control messages and user communications for the calls and interworking the user communications between a first communication format and a second communication format in response to the control messages; and in a control system, receiving and processing the data messages for the calls to maintain an active call database having call data for active ones of the calls, and receiving a query, and in response, processing the active call database to identify one of the active calls that satisfies the query. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
