A method, a mobile device, and a system for message transmission of a vulnerable road user (VRU) are provided. The method is adapted to a first mobile device of a first VRU and includes the following steps. Whether there exists a target mobile device within a preset range of the first VRU is determined, where the target mobile device is a mobile device that has already broadcast a personal safety message (PSM). When the target mobile device exists within the preset range, whether to broadcast a first PSM is determined according to a relative distance between the target mobile device and an intersection as well as a relative distance between the target mobile device and the first mobile device. When the target mobile device doesn't exist within the preset range, the first PSM is broadcast.

Method, mobile device, and system for the message transmission of a vulnerable road user

A method of dynamic adjusting a generation frequency of messages in vehicular networks is provided, including: receiving updating requests and emergent degree of the vehicle event, and then determining whether the generation frequency of messages meets the dynamic change of the vehicle, if not satisfied, selecting a different adjustment method according to the event emergent degree. When the event is emergent, its generation frequency can be raised immediately by an interruptive adjustment and to suppress the generation frequency of messages of the others. Conversely, adjusting its generation frequency by a progressive adjustment and reducing the generation frequency of messages of the other lower-priority vehicles. According to the present disclosure, it prevents lower priority messages from occupying the channel overly, and emergency messages with higher priority can be satisfied immediately when it needed.

System of dynamically adjusting generation frequency of messages in vehicular networks and method thereof

An automatic photographing method is provided. The method includes the steps of: receiving a dialing message from a telecommunications network; recognizing a phone number from the dialing message, and controlling a camera module to take at least one photo according to the dialing message; and performing image processing to the photo to generate photo data corresponding to the phone number.
