A subscriber database, in at least one embodiment, stores RF level and timing advance information associated with all mobile telephones on a network. A location parameters database stores location data that associates different physical locations with RF levels/timing advance data that have been measured or inferred for those locations. The subscriber database is then interpreted for the purpose of establishing the location of a specific mobile telephone at a given time by matching the RF level/timing advance data for that specific mobile telephone against the location parameters database. This generates the location of the mobile telephone. The interpretation or querying of the subscriber database only occurs, however, when there is a request to establish the location of a specific mobile telephone, and not as an automated process applied to all mobile telephones on a network.

Method of finding a physical location of a mobile telephone at a given time

A configurable user-interface component management system and method are provided where frame containers contain a number of child components and user-interface components. The frame containers and their children are arranged in a specific hierarchy that determine their on-screen appearance. The hierarchy is a result of the software architecture of the software objects corresponding to the visual on-screen objects. The user-interface components in each visual component are configured based on certain, predetermined policies. The method of managing the frame containers and their children includes waiting for an event that affects a frame and then responding by creating a frame, destroying a frame, changing a hierarchy order, moving a frame from one hierarchy to another, or sizing a frame, after which the appropriate policies are removed and applied as needed, affected hierarchies reconfigured and then saved.
