  • Method and apparatus for detecting communication network delays
    Patent number: 6810235
    Abstract: A method and apparatus for detecting communication network delays. In general, messages from vehicles are time stamped, and then the time stamp is compared to a time that each message is received by a central station. A processor at the central station then determines a time difference between the time stamp and the received time. The time difference is then compared to a predetermined time. If more than a predetermined number of messages is received by the central station exceeding the predetermined time, a notification is sent to an entity, such as personnel at the central station.
