Abstract:
In a communication network, circuit-based switches transfer signaling that indicates first circuit-based connections and transfer user communications over the first circuit-based connections. A signaling processor processes the signaling to select header information and second circuit-based connections. The signaling processor transfers control messages indicating the header information and the second circuit-based connections. A first interworking system receives the control messages and the user communications, and in response, transfers the user communications in packets having the header information. A second interworking system receives the control messages and the packets, and in response, transfers the user communications over the second circuit based connections to a plurality of other communication networks.
Abstract:
A communication system comprises a signaling processor and an interworking unit. The signaling processor receives and processes signaling for a call to select a connection and a first bandwidth rate. The signaling processor transfers a first message indicating the connection and the first bandwidth rate. The interworking unit receives the first message and user communications for the call, and in response, transfers the user communications over the connection at the first bandwidth rate. The interworking unit detects a trigger in the user communications, and in response, transfers the user communications over the connection at a second bandwidth rate.
Abstract:
A signaling processor receives a first signaling message indicating a called telephone number for the call. The signaling processor processes the called telephone number from the first signaling message to determine if call validation is required. If the call validation is not required, then the signaling processor processes the called telephone number to determine routing information without the call validation. If the call validation is required, then the signaling processor determines if the call is valid, and if the call is valid, then the signaling processor processes the called telephone number to determine the routing information. The signaling processor transfers a second signaling message indicating the routing information for the call.
Abstract:
A signaling processor processes a first message to select a TDM connection for the call and transfers a second message indicating the selected TDM connection. The interworking unit receives the second message and user communications for the call in a packet format, converts the user communications from the packet format to a TDM format, and transfers the user communications in the TDM format over the selected TDM connection. The interworking unit monitors the user communications for a trigger after call set-up and during the call, and if the trigger is detected, transfers a third message indicating the trigger. The signaling processor receives and processes the third message to select routing information for routing the call to a service platform and transfers a fourth message indicating the selected routing information to route the call to the service platform.
Abstract:
The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates control messages that identify the selection and transfers the control messages to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages.
