Abstract

The inventive method allows for efficient use of network resources utilized for procuring location information in a wireless network. In one implementation, the timing for updating location information utilized to monitor a mobile unit is dynamically set depending, at least in part, on the location of the mobile unit relative to one or more locations of interest. In this regard first time location information for a mobile unit is compared to locations of interest for that mobile unit. Based on this comparison, a timing for updating the location information is determined that will allow for effective monitoring of the mobile unit'"'"'s status relative to one or more locations of interest while reducing network resource usage. For example, as the distance between a mobile unit and a boundary of a location of interest increases, the frequency of obtaining updated location information may be reduced.
