Problems solved by technology

Its shortcoming is that when assigning frequencies to different cells, it fails to make detailed statistics and divisions on the number of users and specific usage conditions, and cannot obtain data on user demand for frequency resources. The resulting frequency planning is often inconsistent with the actual situation. big deviation

Abstract

The invention provides a TD-LTE230 wireless private network frequency resource planning method. The TD-LTE230 wireless private network frequency resource planning method comprises the steps of 1, obtaining the total number of different service types of terminals in a target region, and representing the total number by using kij, wherein i=1, 2, ..., n, and i represents the number of service types, j=1, 2, and j=1 represents the number of existing services, and j=2 represents the number of planned services; 2, distributing the total number kih of the different service types of the terminals averagely according to the number m of the covered sectors, and counting the number hij of the terminals for each service in each sector, wherein hij=kij / m; 3, calculating the demands Kij of different services in each sector for a wireless frequency resource; 4, carrying out frequency point distribution cij for different services in each sector; 5, calculating the number of frequency points C needed by all the services in each sector; and 6, calculating the total number H of the TD-LTE230 wireless private network frequency resources needed by the target region.

Description

technical field [0001] The invention relates to the field of wireless networks, in particular to a frequency resource planning method for a TD-LTE230 wireless private network. Background technique [0002] TD-LTE 230 wireless private network has the characteristics of wide coverage, high transmission rate, real-time performance and strong spectrum adaptability, and is the main technical means of terminal communication access network. In 1991, the State Radio Regulatory Commission issued the "Notice on Printing and Distributing the Frequency Band Planning for Civilian Ultrashort Wave Telemetry, Remote Control, and Data Transmission Services" (Guowuguan [1991] No. 5), the document stipulated that 223.025 ~ 235.000MHz, a total of 12MHz as telemetry, remote control , frequency bands used for data transmission and other services. In addition, with the development of smart grid, especially the gradual application of big data, cloud computing, Internet of Things, and mobile servic...
