Problems solved by technology

[0005] Embodiments of the present invention provide a fault detection method and device for an IP RAN network, which solves the need for operation and maintenance personnel to check the equipment in the IP RAN network when detecting a faulty node or link in the IP RAN network in the prior art. Check one by one and the operation and maintenance personnel need to learn the codes of each manufacturer and the use of equipment, which may easily cause different processing times for different operation and maintenance personnel to detect the node or link where the fault occurs, and cannot guarantee the user experience.

Embodiment 1

[0039] Embodiment 1. Embodiments of the present invention provide a fault detection method for an IP RAN network, such as image 3 Shown include:

[0040] S101. Receive fault alarm information reported by the Ethernet corresponding to the network manager in the IP RAN network.

[0041] It should be noted that, if figure 2 The shown IP RAN equipment can insert and extract OAM packets at different reference points, these reference points are called maintenance points MP, and the OAM functions of each layer can be divided into two types: active and on-demand; Management functions include: Continuity Check (English full name: Continuity Check, abbreviation: CC): the continuity check function is an active OAM function, the source end maintenance endpoint periodically sends OAM messages, and the sink end maintenance endpoint detects the Continuity loss faults, and connectivity faults such as mis-merging and mis-connecting; loopback detection (English full name: oopback, abbreviat...

Embodiment 2

[0110] Embodiment 2. The embodiment of the present invention provides a fault detection device 10 of an IP RAN network, such as Figure 8 Shown include:

[0111] The service creation and management module 101 is configured to receive the fault alarm information reported by the Ethernet corresponding to the network manager in the IP RAN network.

[0112] The service creation and management module 101 is also used to query the fault information database according to the fault alarm information, and generate OAM instructions; wherein, the fault information database includes: a mapping relationship table between fault alarm information and fault detection schemes; the OAM instruction includes: fault detection plan.

[0113] The network collaboration module 102 is configured to send the OAM fault detection command generated by the service creation and management module 101 to the network manager; wherein, the OAM command is used to instruct the network manager to detect Ethernet a...

Abstract

The embodiment of the invention provides a fault detection method and apparatus of an IP RAN network, and relates to the technical field of fault management. The following problem in the prior art issolved: when a faulty node or link in the IP RAN network is detected, the operation and maintenance personnel need to troubleshoot the devices in the IP RAN network one by one, and the operation and maintenance personnel need to learn the codes of the factories and the use methods of the devices, thereby resulting in different handling times of the faulty node or link by different operation and maintenance personnel, such that the user experience cannot be ensured. The method comprises the following steps: receiving fault alarm information reported by an Ethernet corresponding to a network manager in the IP RAN network; querying a fault information library according to the fault alarm information to generate an OAM instruction; issuing the OAM fault detection instruction to the network manager; and receiving and uploading a feedback instruction uploaded by the network manager. The fault detection method and apparatus provided by the embodiment of the invention are applied to the faultdetection of the IP RAN network.

Description

technical field [0001] The present invention relates to the technical field of fault management, in particular to a fault detection method and device for an IP RAN network. Background technique [0002] In the prior art, the service assurance model of the operator-based Internet Protocol Radio Access Network (English full name: Internet Protocol Radio Access Network, referred to as: IP RAN) mainly includes two types of content: Service Quality (English full name: Quality of Service, referred to as: QoS) and operation maintenance management (English full name: Operations Administration and Maintenance, abbreviation: OAM); wherein, OAM usually includes two major functions: fault management and performance management. [0003] In practical applications, the implementation logic diagram of OAM fault management is as follows: figure 1 As shown, Huawei equipment, ZTE equipment, and FiberHome equipment are independently built networks, and are interconnected in pairs at the core s...
