METHOD AND SYSTEM FOR COMMUNICATING TELEMATICS MESSAGES |
摘要 |
Disclosed is a method and system for communicating standardized telematic messages among a plurality of telematic devices. A telematic message is received by a message router from one of the telematic devices. The message router selects a destination device and transmits the message to the destination device, where the message is processed. In one embodiment, the message router determines whether the destination device is available to receive a message before transmitting the message. If the destination device is not available, the message is maintained in memory. In another embodiment, a time-to live parameter is assigned to the message and the message is removed from memory of the time-to live expires before the destination device becomes available. In a further embodiment, a priority parameter is assigned to the message and the processing of a prior message is interrupted if a new message is received that has a higher priority parameter than the previously received message. |
