摘要： The invention relates to a method for evaluating a radio channel to be used for extracting traffic information data with searching for a valid radio channel, tuning to the valid radio channel, and extracting the traffic information from the tuned radio channel. To provide better traffic information, calculating a signal quality level from the tuned channel, calculating a traffic information data level from the number of received traffic information data within the tuned channel, and deciding whether to search for a new radio channel based on a comparison between the signal quality level and the traffic information data level and a threshold value, respectively is provided.

摘要： The invention relates to a method for providing at least traffic data and position data from at least two sources to a handheld computer using one single interface, with obtaining the traffic data using a traffic data receiver, obtaining the position data using a position data receiver, and providing the traffic data and the position data to a message director. To prevent lock-ups on the interface, the invention proposes that the message director receives from the handheld computer via the interface instructions concerning which data to send to the handheld computer, the message director selects from the provided data the data to be send via the interface to the handheld computer according to the instructions, and the message director sends the selected data via the interface to the handheld computer.
摘要翻译：本发明涉及一种用于使用一个单一接口从至少两个源提供交通数据和位置数据至手持式计算机的方法，其中使用交通数据接收器获得交通数据，使用位置数据接收器获得位置数据，并将交通数据和位置数据提供给消息导向器。为了防止接口上的锁定，本发明提出消息引导器经由接口指导从手持计算机接收
