Methods and apparatus for controlling the transmission and/or reception of safety messages by portable wireless user devices
First Claim
1. A method of operating a communications device, comprising:
- generating device location information based on at least one of a received signal or inertial guidance information; and
controlling at least one of a safety message monitoring operation or a safety message transmission operation based on the generated device location information, said step of controlling including controlling;
(i) a safety message monitoring periodicity that determines a rate at which monitoring for safety messages is performed and a safety message monitoring duty cycle based on the generated device location information or (ii) a safety message transmission periodicity that determines a rate at which safety message transmissions are made by said communications device; and
wherein the safety message monitoring periodicity or the safety message transmission periodicity is increased when it is determined that the communications device is at a location with higher vehicular traffic than at another location with lower vehicular traffic.

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.

11. A computer program product for use in a communications device, the computer program product comprising:
-
a non-transitory computer readable medium comprising; code for causing at least one computer to generate device location information based on at least one of a received signal or inertial guidance information; and code for causing said at least one computer to control at least one of a safety message monitoring operation or safety message transmission operation based on the generated device location information, said code for causing said at least one computer to control at least one of a safety message monitoring operation or transmission operation including code for causing said at least one computer to control a safety message monitoring periodicity that determines a rate at which monitoring for safety messages is performed or a safety message transmission periodicity that determines a rate at which safety message transmissions are made by said communications device, and code for causing said at least one computer to control a safety message monitoring duty cycle based on the generated device location information; and wherein said code for causing said at least one computer to control a safety message monitoring periodicity or a safety message transmission periodicity causes said at least one computer to increase the safety message monitoring periodicity or the safety message transmission periodicity when it is determined that the communications device is at a location with higher vehicular traffic than at another location with lower vehicular traffic.
