Abstract

Over time, mobile devices accumulate data. Some of this data is time-stamped and may become stale after a period of time. Users of mobile devices are typically responsible for manually cleaning up their devices by deleting this stale data. This requires the user to periodically search the device for data that they consider stale and manually remove it from the device. The invention periodically examines the data on the device and, based on user preferences, automatically purges time-stamped data that is considered stale. The user does not need to locate old data as it is purged automatically by the system on a regular basis. This keeps more space available for new data that might arrive on the device thus forming a key aspect of providing a reasonable storage profile for a mobile device by controlling the size of organically growing databases. Additional benefits of the invention include maintaining consistent and reasonable backup/restore times, ensuring reasonable search speeds, and assisting enterprise customers who have "retention" policies on how long email is allowed to reside on a wireless device. Data that is purged from the device in this manner is not also deleted from the equivalent server-side repository. For example, stale calendar appointments that are removed from the device are not removed from the user's desktop calendar. Examples of the data that might be purged from the device include email and PIN messages, SMS or MMS messages, phone call logs, calendar appointments, etc. The user can configure the length of time to keep the various types of data on the device. Possible choices might include 15 Days, 30 Days, 90 Days, 120 Days, or Forever.
