Abstract:
Safety message monitoring operations and/or safety message transmission operations are controlled for a mobile wireless communications device. The periodicity with regard to safety message monitoring and/or safety message transmissions is varied based on the environment of the mobile wireless device. The transmission power level with regard to safety message transmissions is varied based on the environment of the mobile wireless device. In some embodiments, safety message monitoring and transmission operations are disabled when the mobile device is determined to be inside a building or inside a vehicle. In some embodiments, safety message monitoring rate and safety message transmission rate is varied as a function of proximity to vehicular traffic and/or the level of detected vehicular traffic. In some embodiments, safety message transmission power level is varied as a function of proximity to vehicular traffic and/or the level of detected vehicular traffic.
