FIELD OF THE INVENTION
The present invention relates to the field of telecommunication communications transport and processing.
SUMMARY OF THE INVENTION
The present invention is directed to a telecommunication system for transporting a call through an asynchronous transfer mode system. The telecommunication system comprises a first communication device adapted to transport a call in a time division multiplex format. The call has user communications and call signaling. The telecommunication system further comprises a second communication device adapted to receive the user communications. A signaling processor is included to receive the call signaling from the first communication device, to process the call signaling to select a connection to the second communication device, and to transport a first processor control message designating the selected connection.
The telecommunication system also comprises an interworking unit adapted to receive the first processor control message from the signaling processor and to receive the user communications from the first communication device. The interworking unit converts the user communications from the time division multiplex format to asynchronous transfer mode cells that identify the selected connection and transports the user communications to the second communication device over the selected connection. The interworking unit monitors the user communications for a call trigger and transports an interworking unit control message to the signaling processor notifying the signaling processor of the call trigger.
The signaling processor is adapted to receive the interworking unit control message and, in response thereto, to process the interworking unit control message to select a third connection to the third communication device. The signaling processor transports a third processor control message designating the third selected connection. The interworking unit is further adapted to receive the interworking unit control message and, in response thereto, to process the interworking unit control message to process the user communications.
Still further, the present invention is directed to a call trigger system for transporting a call between a first communication and a second communication device device through an asynchronous transfer mode system. The call has user communications. The system comprises an interworking unit adapted to receive the user communications from the first communication device on a first connection and to transport the user communications to the second communication device on a second connection. The interworking unit monitors the user communications to detect a call trigger and, upon detection of the call trigger, transports a first control message containing call trigger data.
The call trigger system further comprises a signaling processor adapted to receive the first control message and, in response thereto, to process the call trigger data to select a processing option, and to transport a second control message designating the selected processing option. The interworking unit receives the second control message and, in response thereto, interworks the user communications for the processing option.
In another aspect, the present invention is a telecommunication system for transporting a call through an asynchronous transfer mode system. The call has user communications. The system comprises a first communication device adapted to transport the call over a first connection and a second communication device adapted to receive the user communications from the first communication device over a second connection. The system further comprises a tone detector adapted to monitor the user communications to detect a tone in the user communications and to transport a tone detector control message containing tone data upon detecting the tone.
The telecommunication system also includes a signaling processor adapted to receive the tone detector control message and, in response thereto, to process the tone data to select a processing option. The signaling processor transports a first control message designating the selected processing option. An interworking unit is included in the telecommunication system and is adapted to interwork the user communications between the first communication device and the second communication device, to receive the first control message from the signaling processor, and in response thereto, to interwork the user communications for the processing option.
In yet another aspect, the present invention is a system for transporting a call through an asynchronous transfer mode system. The call has user communications. The system comprises a first communication device adapted to transport the call over a first connection, a second communication device adapted to receive the user communications from the first communication device over a second connection.
The system further comprises an interworking unit adapted to interwork the communications between the first and second connections, to monitor the user communications to detect a call trigger in the user communications, and to transport an interworking unit control message containing call trigger data upon detecting the call trigger. The system also comprises a signaling processor adapted to receive the call data from the interworking unit and, in response thereto, to process the call trigger data to select a processing option. The signaling processor transports a first control message designating the selected processing option. The interworking unit is adapted to receive the user communications from the network, to receive the first control message from the signaling processor, and in response thereto, to interwork the user communications for the processing option.
In still another aspect, the present invention is directed to a method for transporting a call in an asynchronous transfer mode system. The call has user communications and call signaling. The method comprises processing the call signaling in a signaling processor to determine a selected first connection and transporting a first control message designating the selected first connection. The user communications are received in an interworking unit and interworked to asynchronous transfer mode cells that identify the selected first connection designated in the second processor control message. The user communications are monitored to detect a call trigger with call data. The call trigger data is processed to determine a processing option.
Still further, the present invention is a method for transporting a call in an asynchronous transfer mode system. The call has user communications. The method comprises monitoring the user communications to detect a call trigger with call trigger data. The call trigger data is processed to determine a processing option. A control message designating the selected connection is transported from a signaling processor. The user communications are received at an interworking unit and interworked for the processing option designated in the control message.
In yet another aspect, the present invention is a method for processing a call in an asynchronous transfer mode system. The call has user communications and call signaling. The method comprises processing the call signaling to select a connection over which the user communications are to be transported. The method further includes interworking the user communications on a call-by-call basis between a non-asynchronous transfer mode format and asynchronous transfer mode formatted cells that identify the selected connection, transporting the user communications over the selected connection, and monitoring the user communications to detect a call trigger having call trigger data. The call trigger data is processed to select a processing option for the user communications.
In still another aspect, the present invention is a system for processing a call from a first communication device in an asynchronous transfer mode syste
