Abstract: A first communication network transfers a signaling message for a call to a second communication network. The signaling message indicates a first identifier that represents a connection through the first communication network to the second communication network. The second communication network processes the signaling message to select a second identifier. The first communication network transfers a user communication for the call to the second communication network. The user communication has a header indicating the first identifier. In response to the first identifier, the second communication network modifies the first identifier in the header to the second identifier. The second communication network transfers the user communication to a destination node in response to the second identifier in the header of the user communication.

Abstract: A communication system receives a signaling message for a voice communication and processes the signaling message to select a route identifier. The system selects a processing technique for the voice communication, such as compression or encryption. The system processes the voice communication with the selected processing technique. The system adds the selected route identifier to the voice communication. The system adds a processing indicator to the voice communication. The system transfers the voice communication with the route identifier and the processing indicator.

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: 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: IP routes are established between route processors. The route processors change message addresses, so that signaling and data messages between users or between users and a soft switch are routed through the route processors. The route processors transfer data messages over the IP routes and monitor performance of the IP routes. The performance data is provided to a route manager that manages the IP routes to avoid undesirable service quality.

Abstract: A communication method comprises: processing a first message from the user CPE to select a circuit switch from a plurality of circuit switches, and selecting an identifier and a DS0 to route user communications from the user CPE to the circuit switch; transferring a second message indicating the identifier and the DS0 and transferring an SS7 IAM to the circuit switch; receiving the user communications from the user CPE in a packet format having the identifier in headers, and routing the user communications in the packet format based on the identifier in the headers; and receiving the second message and the user communications in the packet format, and in response, converting the user communications from the packet format into a DS0 format and transferring the user communications in the DS0 format over the DS0 to the one circuit switch.

Abstract: Signaling processors process signaling to transfer first and second control messages indicating interworking information. Interworking units receive the control messages and user communications, and in response, convert the user communications into packet communications having the interworking information in headers. Communication devices receive the packet communications from the interworking units and route the packet communications over optical communication paths based on the interworking information in the headers. The communication devices receive the routed packet communications and transfer the routed packet communications to the interworking units. The interworking units receive the second control messages and the routed packet communications, and in response, to convert the routed packet communications into the user communications and transfer the user communications.

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.
