Annular repeater system and network fault repairing method thereof

Abstract

The invention provides an annular repeater system, wherein a near-end base station is connected into a control unit and is connected with far-end radio remote units of each level in the annular repeater system through optical fiber to form a closed annular link; in the annular repeater system, the optical fiber conveyed in the far-end radio remote covering unit is firstly connected with a light bypass unit, and then connected with the light bypass unit through a main optical interface; and the optical fiber coming out of the optical interface are respectively connected with the optical bypassunit and a next level far-end radio remote covering unit. The invention also provides a network fault repairing method of the annular repeater system. In the invention, the annular repeater system isestablished by an annular networking mode, thus realizing the report and auto-repairing of the operation condition of the annular link, being capable of realizing intelligentized management, and improving convenience content of the project maintenance and disaster resistance capability of the system.

Description

technical field [0001] The invention relates to repeater network technology, in particular to a ring repeater system and a method for repairing network faults of the ring repeater system. Background technique [0002] With the development of mobile communication, the site selection and installation of mobile communication base stations are becoming more and more difficult. In order to solve this problem, the repeater system is often used in the network to reduce the cost of base station construction and optimize network coverage. However, the current repeater system generally adopts one-to-one single-point connection, or one-to-many star topology, or a bus topology similar to daisy chain, or a mixture of daisy chain and star topology. The four networking modes of the structure. Specific as Figure 1 to Figure 4 as shown, figure 1 For one-to-one network mode, figure 2 It is a star network, image 3 For daisy chain networking, Figure 4 It is a hybrid networking mode. ...

AI Technical Summary

Problems solved by technology

[0005]3. Daisy chain networking mode: it can make full use of optical fiber resources, and can share a near-end base station access control unit with multiple chains, and the equipment utilization rate is high. However, when there is a sudden failure or power failure at any level in the middle, all subsequent coverage will be paralyzed. Therefore, this networking method has poor stability and low intelligence.

[0006]4. Hybrid networking mode: it can adapt to a variety of different coverage area shapes, and the equipment utilization rate is high, but the network complexity will be increased due to this networking mode Large, resulting in inconvenient management, and at the same time, there is a problem of poor stability in the daisy chain structure

[0007] And in the Chinese patent "Repeater System and Data Interaction Method That Can Adaptively Adjust Networking Mode" with the published application number 200610036413.0, a The implementation of a ring network, as shown in Figure 5 , due to its imperfect monitoring system, when the network fails, the entire system will switch back and forth continuously, and it is easy to enter a state of endless loop, so the system stability is very poor

Since there is no fault reporting function in its monitoring system, the degree of intelligence is not high, which is not conducive to engineering maintenance
