Embodiment approach

[0078] The BSC manages the at least two BBUs mentioned above in real time. When the data of one of the BBUs changes due to manual modification or bearer services, etc., the BSC is responsible for modifying its own base station configuration information in real time and forwarding the relevant modified data to another or multiple BBUs. BBU, that is, to ensure that the data on at least two BBUs are completely consistent. Based on this, this embodiment provides a preferred implementation manner, that is, the above-mentioned BSC includes: a control module, configured to control the above-mentioned at least two BBUs to ensure that the data in the above-mentioned at least two BBUs are consistent. The specific monitoring mode of the BSC can be realized through the following preferred implementation modes:

[0079] The above-mentioned BSC also includes: a first monitoring module for monitoring whether the states of the above-mentioned BBUs are normal; an alarm module for sending an al...

Abstract

The invention discloses a communication method, device and system. Wherein, the method includes: the RRU sends the data interacted with the BBU to at least two BBUs connected to it at the same time; the RRU receives the data interacted with the RRU sent by the at least two BBUs at the same time; One of the BBUs, the data in the at least two BBUs are consistent. Through the present invention, it is ensured that the data exchanged between the RRU and at least two BBUs are consistent, and at least two BBUs are mirror images of each other, which solves the problem of low reliability of the tunnel coverage technology in the related art. The business process of BSC has been improved, and the wireless signal coverage method has been improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a communication method, device and system. Background technique [0002] In most of the Global system for Mobile Communication For Railways (GSM-R) projects, the signal coverage in the tunnel usually consists of donor macro base stations, optical fiber repeaters and leaky cables, that is to say The coverage in the tunnel mainly depends on the remote unit of the optical fiber repeater and the leaky cable section connection, and deploys the entire tunnel to complete the wireless signal coverage of the entire tunnel. [0003] The following introduces common wireless signal coverage methods based on macro base stations and repeaters in related technologies. figure 1 is a schematic diagram of one of the common coverage methods according to related technologies, such as figure 1 As shown, the macro base station (RF donor station) provides a radio frequency signal source by connecti...
