Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The 3GPP standard stipulates that measurement is an important function of the TD-SCDMA system, and the network equipment (NodeB and UE) should have the ability to measure the measurement items specified in the 3GPP standard. Measurement methods include periodic measurement and event-triggered measurement. Measurement items include but are not limited to International Mobile Subscriber Identity (IMSI), measurement sampling time (TIME STAMP), base station number (Scell_ID), received signal code power of Primary Common Control Physical Channel (PCCPCH), Slot interference signal code power, timing advance (Tadv), antenna angle of arrival (AOA), block error rate, UE power level information, etc. (see 3GPP 25.123Requirements for support of radio resource management (TDD), 3GPP 25.225Physical layer; Measurements (TDD)).

[0020] Among them, the value of Tadv in the...

Abstract

The invention discloses an antenna angle optimization method and system. The antenna angle optimization method comprises the steps of acquiring measurement reports and analyzing the measurement reports to obtain sample points, and using the sample points of the same antenna as a cluster group of an antenna; calculating a reasonable direction angle and a reasonable downward inclination angle of the antenna according to the cluster group of the antenna; optimizing a direction angle and a downward inclination angle of the antenna according to the reasonable direction angle and the reasonable downward inclination angle. The antenna angle optimization method and system utilizes measurement reports of a terminal and a base station, calculates the reasonable direction angle and the reasonable downward inclination angle of the antenna according to the sample points of the same antenna in the measurement reports, utilizes the reasonable direction angle and the reasonable downward inclination angle to optimize the direction angle and the downward inclination angle of the antenna, can rapidly, timely and accurately optimize and adjust antenna angles, is high in efficiency, does not depend on work experience of maintainers and can remotely perform antenna optimization without field route measurement.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to an antenna angle optimization method and system. Background technique [0002] The azimuth and downtilt of the cell antenna are important engineering parameters in the mobile communication network, and the rationality of their setting basically determines the coverage effect of the entire network. With the construction of mobile communication networks and changes in the wireless environment, operators need to optimize and adjust the azimuth and downtilt angles of cell antennas in a timely manner to ensure the overall network coverage and quality requirements. [0003] At present, in the TD-SCDMA network, there are two ways to optimize and adjust the cell antenna: [0004] 1. Road test: Carry out road test through DT test software, analyze and find weak coverage, over-area coverage, and unreasonable coverage road sections, then find out the main service area covering th...
