Abstract: Aspects of the invention disclose a method and system for automatically updating traffic incident data for in-vehicle navigation. This includes, but is not limited to, a method and system of notifying one or more traffic providers of a traffic accident when a telematics provider receives an automated accident notification from a vehicle. The notification prompts the traffic provider to investigate the traffic accident immediately using manual techniques (monitoring police scanners, visual confirmation by aircraft, etc.) and accurately updates its traffic information in a more timely manner. In turn, the traffic information received by the telematics unit from traffic provider is more accurate. This allows the telematics unit navigation system to provide accurate navigation directions to the subscriber while driving through traffic congested areas.

Abstract: The disclosed examples illustrate a system and method that prevent excessive current drain through the network access device (NAD) of a telematics unit and provide flexible discontinuous-receive management. Normally, when in a Standby State and where communication service is unavailable, the NAD may dissipate current at rate many times more than where communication service is available. A Standby Counter provides the length of the time interval for Standby State or the sleep cycle. Certain of the disclosed examples prevent excessive vehicle battery drain by operating the telematics unit in a first mode wherein a sleep cycle value of the telematics unit is above a first predetermined threshold, and if the communication service is available, operating the telematics unit in a second mode wherein a sleep cycle value is in a range from zero to the first predetermined threshold.
