first embodiment
[0123]In a first embodiment, the service platform communicates using SMS messages wherein each comprises a string of up to 160 characters. It will be apparent that the server platform may also and alternatively comprise another wireless module, which is able to serve as a master wireless module to supervise the asset management operations of one or more slave wireless modules.
[0124]The data processing means (60) provides the capability to transform the wireless module (10) from being an end point of data or voice communication into being a programmable gateway, which is able to communicate with a range of external devices or functional elements connected via the port module.
[0125]FIG. 2 illustrates the different applications controlled by the wireless module in the particular example where the mobile telecommunications network operates according to the GSM standard. It will be clear to those skilled in the art, which changes must be made to the wireless device and to the messaging p...
second embodiment
[0178]In the same invention, particular details of the system and method according to the application to vehicle guidance systems are now described in more detail. As mentioned, the wireless module has the capability to receive and store data for the purpose of updating data stored in the memory of an associated asset. In the particular example of the GPS vehicle guidance system, the in-vehicle GPS system calculates a position fix from the transmissions received from a number of satellites in the moving constellation of GPS satellites. This position fix is computed in the form of a geographical coordinate and compared with the coordinate-encoded map data in the vehicle guidance system. In order for the system to be useful, the map data must be up to date. According to the invention, as new roads become opened and knowledge becomes available of planned road works, it is advantageous that this data is transmitted using the mobile network infrastructure in the form of messages sent to ...
