Abstract: An application service server, a region-based information processing method, and user equipment are provided. In the method, an initial message is received, identification information is determined according to the location information of the initial message, and a preprocessed message is generated. The initial message includes a notification content corresponding to the location information, and the location information is defined by a geographic coordinate system. The identification information is provided by a geographic information service. The preprocessed message includes the notification content and the identification information.

Abstract: A method for determining the position of a mobile node applied to a roadside unit (RSU) is provided. The RSU and a plurality of mobile nodes form a communication network of a road. The method includes the steps of: obtaining, by, via at least one sensor, first road information, wherein the first road information provides absolute position distribution information associated with the mobile nodes; receiving, by a communication device, second road information from a first mobile node of the mobile nodes, wherein the second road information provides relative position distribution information associated with the first mobile node and second mobile nodes adjacent to the first mobile node; and determining, by a comparison device, the position of the first mobile node on the road according to the first road information and the second road information.

Abstract: 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.
