An indoor and outdoor user terminal discrimination method and a base station

Abstract

The embodiment of the invention provides an indoor and outdoor user terminal judgment method and a base station. The method comprises the steps that MDT data sent by an undetermined user terminal in apreset area is acquired, and if it is judged that the MDT data do not comprise GPS information, the MDT data sent by a plurality of auxiliary judgment user terminals in the preset area are acquired;Wherein the MDT data sent by the auxiliary discrimination user terminal comprises GPS information; According to the MDT data of the undetermined user terminal and the MDT data of each auxiliary discrimination user terminal, determining a target auxiliary discrimination user terminal in the plurality of auxiliary discrimination user terminals; And performing indoor user terminal or outdoor user terminal judgment on the undetermined user terminal according to the RSRP values respectively corresponding to the undetermined user terminal and the target auxiliary judgment user terminal. According tothe method and the base station provided by the invention, the indoor and outdoor user terminal discrimination efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for discriminating indoor and outdoor user terminals and a base station. Background technique [0002] Coverage is the soul of the mobile network. The user terminals covered by the mobile network can be divided into indoor user terminals and outdoor user terminals. For indoor user terminals, wireless signals will be greatly attenuated by walls and other barriers, resulting in deep coverage of indoor signals. question. Since most of the mobile network services take place indoors, in order to obtain the indoor signal coverage, which is one of the important factors affecting the service quality of the mobile network, it is necessary to effectively distinguish between indoor user terminals and outdoor user terminals. [0003] Under the existing technical conditions, the identification of indoor and outdoor user terminals in the Long Term ...

Problems solved by technology

The above method relies too much on the TA, AOA and map grid, and because the wireless signal propagates in the complex environment of the urban area, it is blocked by buildings, etc., and phenomena such as reflection, refraction, and diffraction will occur and affect the use of TA and AOA for user terminals. The positioning accuracy of the location information, and the location information of all user terminals needs to be calculated separately; moreover, the size of the map grid is limited by the MR positioning accuracy, and the above factors greatly affect the identification efficiency of indoor and outdoor users
