  • Call failure recording
    Patent number: 7502447
    Abstract: A method and device for recording call failure information in a data transmission system is provided. The failure logs generated in response to a failure event include a failure type and a first timestamp. A log record is created for a first failure log based on the failure type, and storied in a log record storage. Whenever a further failure log is generated in response to the same failure event, the further failure log includes said failure type and a current timestamp, so that it will receive the same identifier. The log record is updated to document the current timestamp.
