Abstract
A system and method for classifying the user'"'"'s morphology, and using that classification to control the UE in order to provide more efficient operation of the UE. The classification may be used to assist the user in determining its location more efficiently, without needless interruption or unnecessary use of system resources. The morphology classifier may classify the user'"'"'s morphology into at least one of the following classifications: indoor, outdoor, local coverage, no local coverage, proximate to a base station, stationary, moving, urban, suburban, rural, deep indoor, mid indoor, and indoor near window. The classification may be used by the UE or by a remote server that utilizes the classification to develop assistance data that is sent to the UE.
