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.
Claims3
An apparatus for detecting communication network delays, comprising:
- a receiver for receiving a message from a vehicle, said message comprising a time stamp indicating when the message was transmitted;
- a processor for determining a time that the message was received, for determining a time difference between the time stamp and the time when the message was received, for comparing the time difference to a predetermined time, for determining a number of messages received having a time difference greater than said predetermined time, and for generating a notification if said number of messages received having a time difference greater than said predetermined time exceeds a predetermined number;
- and
- an interface for providing said notification to an entity.
A signal-bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform a method for detecting communication network delays, said method comprising operations of:
- receiving a message from a vehicle, said message comprising a time stamp indicating when the message was transmitted;
- determining a time that the message was received;
- determining a time difference between the time stamp and the time when the message was received;
- comparing the time difference to a predetermined time;
- determining a number of messages received having a time difference greater than said predetermined time;
- and
- generating a notification if said number of messages received having a time difference greater than said predetermined time exceeds a predetermined number.
