Abstract:
1. A method for monitoring a call associated with a connection established via a Media Gateway node, the Media Gateway node being controlled by a Media Gateway Controller node, the method comprising: detecting a loss of communication between the Media Gateway Controller node and the Media Gateway node; 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; determining, in response to a re-establishment of the communication between the Media Gateway Controller node and the Media Gateway node, whether the connection associated with the call is still active at the Media Gateway node; determining the charging time based on the time stamp of the detected communication loss in response to determining that the connection associated with the call is not still active upon the re-establishment of the communication between the Media Gateway Controller node and the Media Gateway node.
