Public and private network interference checking method and device

Abstract

The embodiment of the invention provides a public and private network interference checking method and a device, and the method comprises the steps: obtaining a public and private network interferencecell list according to sweep frequency data and a cell work parameter table; wherein the public and private network interference cell list is a corresponding relation table between each private network cell and each public network cell; and determining an interference cell corresponding to any private network cell according to the RSRP difference between any private network cell in the public andprivate network interference cell list and each public network cell. According to the public and private network interference checking method and the device, an RSRP difference value of a public andprivate network cell is obtained through sweep frequency data to perform interference checking; the public and private network interference checking method based on the SINR value solves the problemsof poor accuracy, low efficiency and non-intuitiveness of the public and private network interference checking method based on the SINR value, effectively improves the public and private network interference checking efficiency and accuracy, and is helpful for workers to more intuitively obtain the public and private network interference situation and perform corresponding adjustment so as to ensure the stability of the private network.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a method and device for troubleshooting interference in public and private networks. Background technique [0002] At present, the dedicated mobile communication network for high-speed railways (GT-LTE) is a digital wireless communication network based on the Global System for Mobile Communications (LTE) platform and specially developed for high-speed railway user applications. As an important driving force for railway informatization, GT-LTE has the characteristics of complete functions, reliable transmission, low delay, high speed, and large capacity, and has been widely used in high-speed railways in various provinces in my country. [0003] GT-LTE adopts F, D2, and D3 tri-frequency networking, and the interference situation is more complicated compared with the public network system. Due to the scarcity of frequencies and the constru...
