System and method for monitoring and reporting telematics unit communication network system acquisition and scanning performance

摘要

A system and method for monitoring and reporting telematics unit communication network system acquisition and scanning performance is disclosed herein. An example of the method includes monitoring a scan of all cellular networks that are available to a vehicle telematics unit, and during the monitoring, recognizing a predetermined trigger. In response to the predetermined trigger, a memory buffer in the telematics unit stores data associated with at least one of performance or outcome of the scan. At least some of the stored data is transmitted from the telematics unit to a server in selective communication with the telematics unit.
