Embodiment Construction

[0028] The NES system utilizes the characteristics of the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, and uses NES terminals to send measurement data at designated frequency points and uplink time slots. NES terminals are vehicle-mounted devices , the NES terminal sends measurement data to the base station at different locations in the area to be optimized, so as to realize the function of reverse coverage measurement of the base station. When the NES terminal sends the measurement data, it sends the measurement data to several base stations through one NES terminal, that is, the "single send and multiple receive" method is used to send the measurement data, so when the base station receives the measurement data sent by the NES terminal, no Co-channel interference can accurately determine the received power of the received measurement data, thereby improving the accuracy of wireless network optimization.

Abstract

The invention discloses a method and a device for optimizing a wireless network and aims to solve the problem in the prior art that the wireless network optimization is inaccurate. The method comprises the steps that the actual path loss of a base station to each position in a plot according to the receiving power of measurement data, which is received by the base station and transmitted by NES (network element) terminals in each position of the plot corresponding to the base station, and the stored transmission power of the measurement data transmitted by the NES terminals; the propagation model of the base station corresponding to the plot is reversed according to the actual path loss of the base station to each position of the plot, and the wireless network optimization for the plot is carried out according to the signal transmission power of the base station corresponding to the plot and the revised propagation model. According to the embodiment of the invention, the base station cannot generate co-channel interference when receiving the measured data transmitted by the NES terminals, the actual path loss can be accurately determined, the propagation model can be accurately revised, and the accuracy of wireless network optimization is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for optimizing a wireless network. Background technique [0002] Improving the quality of wireless network coverage is the most important means to ensure communication quality and improve user perception. Usually, the method of wireless network optimization is used to improve the quality of wireless network coverage. [0003] In the prior art, there are mainly two methods for wireless network optimization. The first method is specifically to select a suitable test point according to the geographical characteristics of the coverage of the cell, or determine the location of the user according to the complaint information of the user, and place the The position of the user is used as the selected test point, and the received signal code power (Received Signal Code Power, RSCP) of the primary common control physical channel (Primary Common C...
