Abstract

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.

Description

[0001] Cross References to Related Applications [0002] Scope of Claims of This Application Claims priority under 35 U.S.C. §119 to the following application: US Provisional Application No. 61 / 589,250, filed January 20, 2012, entitled "MDT Location Option Control." This application is hereby incorporated by reference in its entirety. technical field [0003] The embodiments disclosed in the present invention are related to positioning in wireless communication technology, more specifically, related to a location option control method and determining the best UE-based positioning procedure Methods. Background technique [0004] In order to verify and test radio network configuration and operation, drive tests have been employed. Path testing typically involves the use of specific test tools that can be driven or carried through an area to gather data for network operation verification. Therefore, manual testing and verification of radio network operation is very common. ...
