Abstract

Apparatus, a method and a computer program product periodically determine one or more temperature thresholds and configuration settings attributable to one or more user equipment coupled to a vehicle. The one or more determined temperature thresholds and configuration settings are sent to the one or more user equipment in a thermal management scheme message. The one or more user equipment are adapted to adjust an operational threshold in response to the received thermal management scheme message.
