摘要： Methods, systems and computer program products for filtering generally-broadcast messages received by a movable unit based on current spatial position, stored trajectory history, and probable future trajectories. A current spatial position of the movable unit is received and stored to form a stored trajectory history. A generally-broadcast message relating to a target geographical region is also received and stored. Potential trajectories of the movable unit are then computed over a pre-determined time based on at least one of the current spatial position, a current travel direction of the movable unit, and the stored trajectory history of the movable unit. The generally-broadcast message is then disseminated in response to at least one potential trajectory crossing into the target geographical region during the pre-determined time period. The generally-broadcast message may also be disseminated on the basis of specified user preferences.

摘要： A message filtering system is provided for filtering generally broadcast messages received by a movable unit. The generally broadcast message includes an information segment including location, time and/or velocity information relating to an event of potential interest to the unit which has occurred in the past and which has continuing consequences for the unit. The movement history of the unit is stored along with data selection information and a determination is made as to whether the information contained in the broadcast information segment is of interest based on this stored information.

摘要： A system for determining whether information broadcast by a general transmitter is relevant to a particular user based on the location, velocity and/or time of an object of interest includes a remote terminal, a general broadcasting unit, a transmitter at the general broadcasting unit for broadcasting messages including a segment comprising a region, a velocity and/or a time corresponding to an event, as well as an event specific tag, and storage for storing selection criteria including current position, time and/or velocity information of the user and/or manually entered data of interest. The selection criteria may also include event specific tags. The receiver at the remote terminal receives the messages from the transmitter at the general broadcasting unit. A navigational receiver may also be used to acquire navigational information from an appropriate external source. A matching processor at the remote terminal evaluates the segment in the messages, determines if the segment sufficiently matches the stored selection criteria and outputs a match signal. A processor in the remote unit receives the match signal, and processes and disseminates the message in accordance with the match signal.
