Problems solved by technology

As a kind of distributed base stations, distributed time division duplex (Time Division Dual, TDD) base stations, most of them do not support the interception function. In order to ensure the communication quality of distributed TDD base stations in the authorized network, most operators Carriers usually use the method of network planning and Global Positioning System (GPS) synchronization to avoid signal interference. This method is good, but it brings huge network maintenance costs for operators.
And this method is only applicable to authorized networks with network planning conditions, and not applicable to unauthorized networks without network planning conditions

Abstract

The embodiment of the invention relates to an air interface interception method, device and system based on an LBT, and a medium. The method comprises the steps: switching a working mode of a distributed base station system into an FDD mode during air interface interception, configuring all subframes in an FDD frame structure to work at an uplink moment, and intercepting an uplink interference signal on all subframes of the FDD frame structure, and when the intensity of the uplink interference signal is not greater than a preset threshold, switching the working mode of the distributed base station system to a TDD mode, so that the distributed base station system provides business service in the TDD mode. According to the embodiment of the invention, the method can meet the demands of the distributed base station system for the LBT function, and also can guarantee the normal business service of the distributed base station system.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of communications, and in particular, to an LBT-based air interface interception method, device, system, and medium. Background technique [0002] In related technologies, a distributed base station system can introduce base station signals into each indoor area through a wired method, and transmit base station signals through indoor antennas to achieve the purpose of eliminating indoor signal coverage blind spots. As a kind of distributed base stations, distributed time division duplex (Time Division Dual, TDD) base stations, most of them do not support the interception function. In order to ensure the communication quality of distributed TDD base stations in the authorized network, most operators Carriers usually use the method of network planning and global positioning system (Global Positioning System, GPS) synchronization method to avoid signal interference. This method is goo...
