Abstract
An apparatus and method for tracking a large number of wireless terminals being used by wireless subscribers in a wireless network and for estimating the location of the terminals at each instant. Some embodiments of the present invention use a coordinated smoothing over time of when location requests should be issued to a location engine, for the large number of subscribers. The smoothing can be used in conjunction with a throttling of location requests, such as when the maximum rate of location request transactions that is supported by the wireless network is exceeded.
