<p><P>PROBLEM TO BE SOLVED: To provide a system and method for efficiently updating the versions of stored datasets on a wireless device. <P>SOLUTION: A wireless device has a resident dataset version summary file that identifies the version of each resident dataset, and upon the wireless device attempting (80) to communicate with a download server, the wireless device compares the version of each specific resident dataset listed in the resident dataset version summary file with the version of downloadable datasets resident on the download server to thereby determine (90) if the version of a wireless device resident dataset is different from the versions of a download server resident dataset. If the download server resident dataset is more recent, the wireless device can download (92) it to overwrite the wireless device resident dataset. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
