Method and device for determining wireless network of multiaerial system

Abstract

The invention discloses a method for determining the wireless network of a multiaerial system, belonging to the wireless technology field. The method comprises the following steps: determining broadcast wave beam shaping figures which correspond to all cell antennae according to the attribute of the range of all cells needing to be covered in a wireless network; determining broadcast wave beam weight values of all the cell antennae according to the determined broadcast wave beam shaping figures of all the cell antennae; replacing the original broadcast wave beam weight values of all the cell antennae by the determined broadcast wave beam weight values of all the cell antennae; and determining the coverage area of the wireless network according to the replaced broadcast wave beam weight values of all the cell antennae. The invention also discloses a device for determining the wireless network of the multiaerial system. Through the method and the device for determining the wireless network of the multiaerial system, the inclination angle, the direction angle, the hanging height, and the like of the antennae do not need to be adjusted manually, and corresponding accurate broadcast wave beam shaping figures can be obtained, thereby an immediately constructed network can be more accurately simulated, and the advantages of the multiaerial system can be fully exerted.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method and device for determining a wireless network of a multi-antenna system. Background technique [0002] Wireless network planning is a very important link in the construction of mobile communication networks. The goal of wireless network planning is to obtain the best possible coverage (Coverage), the largest possible system capacity (Capacity), and serve as many users as possible with the least possible cost (Cost), while ensuring certain Communication quality (Quality). In the process of wireless network planning, it is necessary to determine the network to be built, and it is necessary to use various technical means and methods to simulate or simulate the network to be built. It can understand the characteristics of the network before the actual network construction, or find out the problems in the project requirements. defects, greatly reducing the risk of...

Problems solved by technology

[0006]Currently, the wireless network determination method adopted by the TD-SCDMA system expansion test network is still based on the experience of the original GSM network and WCDMA network, and the main wireless coverage prediction adjustment The method is to adjust the coverage area of ​​the cell by mechanically adjusting the antenna's inclination angle, direction angle, and hanging height, and only obtain the corresponding broadcast beamforming diagram according to the broadcast beam weights assigned by the multi-antenna factory. However, due to the multi-antenna Compared with the single-antenna system, the system is more complicated, which consumes manpower and cannot accurately adjust the coverage of the cell range, so that the network cannot be accurately simulated and the advantages of the TD-SCDMA multi-antenna system cannot be fully utilized.
