Location option control for minimization of drive test in LTE systems

摘要

A method of providing location option control for Minimization of Drive Test (MDT) in LTE systems is provided. In one embodiment, a UE or an eNB receives an MDT location request that comprises an MDT location option configuration having one or more location options. The UE or eNB determines a first location option based on the MDT location option configuration and initiates positioning for MDT measurements, reporting, and logging according to the first location option. In one novel aspect, each location option is associated with a priority. In addition to MDT measurements, reporting, and logging, a UE determines the best positioning procedure from a list of available location options. In one novel aspect, under a specific positioning objective, the UE prioritizes the list of available location options based on the signal strength and/or quality of cellular and WLAN signals.
