Embodiment 1

[0067] see figure 1 The outfield maintenance method of the radio remote unit in Embodiment 1 of the present invention is applied to a terminal device, and the outfield maintenance method includes:

[0068] Step 11: Send an acquisition instruction to the remote radio unit through a wireless signal;

[0069] Step 12: receiving the intermediate data information fed back by the remote radio unit through the wireless signal according to the acquisition instruction;

[0070] Step 13: Preprocessing the intermediate data information to complete the maintenance of the radio remote unit.

[0071] The remote radio unit maintenance method provided by Embodiment 1 of the present invention performs information interaction with the remote radio unit through wireless signals, and completes the maintenance of the remote radio unit without changing the remote radio unit (RRU) of the existing network. The structure supports independent diagnosis when the RRU is disconnected, which not only red...

Embodiment 2

[0083] see figure 2 The outfield maintenance device of the radio remote unit in Embodiment 2 of the present invention is applied to terminal equipment, and the outfield maintenance device includes:

[0084] The first sending module 21 is configured to send an acquisition instruction to the radio remote unit through a wireless signal;

[0085] The first receiving module 22 is configured to receive the intermediate data information fed back by the remote radio unit through a wireless signal according to the acquisition instruction;

[0086] The preprocessing module 23 is configured to preprocess the intermediate data information to complete the maintenance of the remote radio unit.

[0087] The external field maintenance device of the remote radio unit provided in Embodiment 2 of the present invention performs information interaction with the remote radio unit through wireless signals, and completes the maintenance of the remote radio unit without changing the remote radio uni...

Embodiment 3

[0100] see image 3 The field maintenance system of the radio remote unit in the third embodiment of the present invention includes: the above-mentioned terminal device 31, and also includes a wireless communication module 33 connected to the radio remote unit 32 by wire, the terminal device 31 and the wireless The communication modules 33 communicate through wireless.

[0101] The external field maintenance system of the remote radio unit provided by Embodiment 3 of the present invention communicates wirelessly with the wireless communication module through wireless signals, and then performs information interaction with the remote radio unit to complete the maintenance of the remote radio unit without changing The structure of the remote radio unit (RRU) in the existing network supports independent diagnosis when the RRU is disconnected, which not only reduces the maintenance cost of the RRU in the field, but also is more convenient and practical.

[0102] Specifically, the...

Abstract

The invention provides an external field maintenance method, device and system for a radio remote unit, and a terminal device. The external field maintenance method comprises the steps of sending an obtaining instruction to the radio remote unit through a wireless signal; receiving intermediate data information fed back by the radio remote unit through the wireless signal according to the obtaining instruction; and preprocessing the intermediate data information and finishing maintaining the radio remote unit. According to the scheme provided by the method, the devices and the system, information interaction with the radio remote unit is carried out through the wireless signal, so the radio remote unit is maintained, and the structure of the radio remote unit RRU of a present network is not changed. Independent diagnosis is supported when the link of the RRU is broken, the external field maintenance cost for the RRU is reduced, and the convenience and practicability are realized.

Description

technical field [0001] The present invention relates to the technical field of base station equipment maintenance, in particular to an outfield maintenance method, device, terminal equipment and system for remote radio frequency units. Background technique [0002] As we all know, as a part of the base station system, RRU (Radio Remote Unit) is the last link for user terminals. It is externally connected to BBU (Building Baseband Unit) through optical fiber for uplink and downlink baseband data transmission; internally completes baseband, Digital intermediate frequency and radio frequency signal processing, and finally transmit or receive radio frequency through the antenna to complete the communication with the user terminal. [0003] In actual use, RRU equipment is usually installed on sites of other high-rise buildings such as iron towers and roofs. During maintenance, it is necessary to bring a laptop and an online site for troubleshooting by someone who understands RRU,...
