Problems solved by technology

[0003] At present, the link detection for digital indoor distribution equipment is mainly through manual inspection. The more RHUBs and PRRUs connected to the 5G digital indoor distribution system, the greater the workload of investigation, the lower the efficiency, and the statistical problems cannot be timely and effective.
That is to say, the fault handling method for digital room distribution equipment in the prior art can only isolate faulty nodes through manual investigation, which does not affect the entire system, but cannot completely self-heal

Embodiment Construction

[0043] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0044] The digital room sub-system is mainly composed of BBU, RHUB and PRRU. The BBU and RHUB can be linked in star and chain mode. The chain mode can be cascaded to four levels, and the transmission medium is optical fiber. The PRRU is connected to the RHUB through a star link. One RHUB can link up to 8 PRRU devices in a star link. The transmission medium can be optical fiber or Ethernet cable. The topology diagram of a digital room distribution system provided by the prior art is as follows: figure 1 shown. In actual engineering applications, a large number of optical fiber links and network cable links are involved. If the link is disconnected, the interface is ab...

Abstract

The embodiment of the present invention discloses a self-inspection method for a baseband unit, an extension unit, a radio frequency unit, and a digital room sub-equipment. The port status information of each device is detected by the port status detection module of each digital room sub-equipment, and the link quality detection module determines Link quality information, the radio frequency channel detection module determines the output power information, which can clearly feedback the link status of the digital indoor distribution system, and has a self-recovery function, which is convenient, automatic and fast to locate the link problem of the digital indoor distribution system, which is convenient for engineering maintenance and Device activation and troubleshooting.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a baseband unit, an extension unit, a radio frequency unit and a method for self-inspection of digital room sub-equipment. Background technique [0002] 5G (the 5th Generation, fifth-generation mobile communication technology) digital room distribution system consists of BBU (Base bandUnite, baseband unit), RHUB (RRU (Remote Radio Unit) Hub, expansion unit) and PRRU (Pico RemoteRadio Unit, radio frequency unit) The RHUB and PRRU devices are connected to the BBU or PRRU through optical fibers or network cables. A complete digital room sub-system includes at least 4 RHUBs and 32 PRRUs. The number of optical fibers and network cables involved is very large. The digital room When the sub-system is being constructed on the project site, some equipment link failures sometimes occur, including abnormal link quality and abnormal radio frequency link gain, etc., which affect the on...
