  • Technique for Monitoring a Call
    Publication number: 20120178413
    Abstract: A technique for monitoring a call associated with a connection established via a Media Gateway node (MGW) is described. The Media Gateway node (MGW) is controlled by a Media Gateway Controller node (MGC). The Media Gateway node (MGW) and the Media Gateway Controller node (MGC) belong to a layered network (LN). A method implementation of this technique comprises the steps of detecting a loss of communication between the Media Gateway Controller node (MGC) and the Media Gateway node (MGW) and logging the loss of communication together with a time stamp of the detected communication loss to be used for determining a charging time of the call.
