A method and apparatus for call quality troubleshooting and mitigation may include polling network communication path elements to determine network performance data, receiving a call quality alert from at least one communication unit, the call quality alert indicating degraded call quality of a call session, and analyzing the network performance data from the network communication path elements and the at least one communication unit to determine a cause of the alert and at least one action to mitigate the cause of the alert. The apparatus for call quality troubleshooting and mitigation may include a memory for storing data from network communication path elements and data from at least one communication unit, and a processor operating to poll network communication path elements to determine network performance data, to store a call quality alert received from at least one communication unit in the memory, and to the network performance data from the network communication path elements and the at least one communication unit to determine a cause of the alert and at least one action to mitigate the cause of the alert. The method and apparatus may further include correlating the data from the network communication path elements with the data from the at least one communication unit and invoking a real-time network topology investigation module to determine the cause of the call quality alert.

Method and system for automated call troubleshooting and resolution

A telecommunications system having a first PS network, second PS network and a third circuit-switched core network includes a system for terminating a legacy domain circuit-switched communication upon receipt of a trigger signal requesting termination of communication. The system includes first and second functional entities in each network. The first and second functional entities of the first network can communicate signals over an interface using a PS protocol. The first and second functional entities of the second network can communicate signals over an interface using a PS protocol. The first functional entity of the first network can communicate packet data to and from the first functional entity of the second network. The second functional entity of the first network communicates a PS protocol signal to the second entity of the second network, which then communicates a circuit-switched protocol signal to and from the third circuit-switched protocol core network to terminate the circuit-switched communication.
