A multi-service isolation method for electric power wireless private network system

Abstract

The invention relates to a method for isolating multiple services in a power wireless private network system, which includes: frequency resource scanning and interference statistics, configuration control and data channel resource pools, broadcast service lists and channel resources, obtaining random access resource pools, establishing connections and Report service ID and base station configuration control and data channel resources. The present invention uses spectrum sensing technology to obtain the frequency usage and interference in the 230MHz spectrum range, thereby effectively evaluating the interference level of each frequency sub-band, and when it is found that the frequency point has been used and the interference is large, it needs to be avoided in time, and dynamically select no interference or For sub-bands with less interference, update frequency resources that can be allocated, allocate dedicated resources for high-priority services, configure multiple transmission resource pools that are physically isolated from each other, for different types of services, and support the flexibility of multiple transmission resource pools Configuration to adapt to regional spectrum resource differences and terminal distribution differences to improve resource usage efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for isolating multiple services in a power wireless private network system. Background technique [0002] The power wireless private network communicates based on the 230MHz dedicated frequency band allocated by the State Radio Regulatory Commission. Its frequency points are discretely distributed in a total of 12MHz bandwidth from 223MHz to 235MHz, and each frequency point has a bandwidth of 25KHz. In addition, there are 360 ​​frequency points within this frequency range (A total of 9MHz bandwidth) is approved by the radio management offices of various cities and needs to be applied for use. With the application and promotion of electric power wireless private network, 230MHz electric power wireless private network, 230MHz data transmission radio station and other high-power radio stations may coexist in the spectrum of 230MHz frequency band at the same t...
