Embodiment 1

[0067] This embodiment specifically discloses a method for fault determination of a base station NODEB in a TD-SCDMA (Time Division-Syn-chronization Code Division Multiple Access) network.

[0068] First, the alarm information of the base station is collected in real time according to a predetermined time period and stored. like figure 1 As shown, visit OMC (Operation and Management centre) server according to the predetermined time period, judge whether can establish connection with OMC, if can establish normal connection, then obtain all base station alarm information in the described time period, after obtaining all When the base station alarm information is described, the counter is used to count and number the collected alarm information, and after a time period ends, the number of the last collected alarm information is recorded, so that when the alarm information is collected in the next time period, the alarm The number of the information is accumulated on the basis o...

Embodiment 2

[0085] The base station in Embodiment 1 can be replaced with any network element in any network, such as an RNC (Radio Network Management) radio network controller in a 3G network, a wireless terminal, and a base station in a 4G network, that is, this embodiment provides a network Meta-fault judgment methods, such as Figure 4 As shown in the figure, the method includes: S1. real-time collecting alarm information of network elements according to a predetermined time period, and storing; S2. obtaining unprocessed alarm information from the stored alarm information according to the alarm processing flag bit; S3. according to the network element The element ID groups the unprocessed alarm information and analyzes each group of unprocessed alarm information to locate the network element fault type; S4. If the network element fault type cannot be located, perform fault prediction based on historical fault information and locate the log Extraction type; S5. Access the network elemen...

Embodiment 3

[0088] This embodiment specifically discloses a system for judging a base station fault. The system includes:

[0089] like Figure 5 As shown, the base station fault judgment system includes three modules: a base station alarm collection module, a base station fault analysis and prediction module, and a base station log extraction module. Each module works as follows:

[0090] The base station alarm collection module is used for real-time collection and storage of base station alarm information according to a predetermined time period, and the processing flag bit of the collected alarm information is set as unprocessed during storage. The alarm collection module numbers the collected alarm information through the counter, and records the alarm number.

[0091] The base station failure analysis and prediction module searches for unprocessed alarm information in the stored alarm information according to the alarm processing flag, groups the unprocessed alarm information accor...

Abstract

The invention relates to the wireless network technology, in particular to a method for judging a fault of a network element. The method for judging the fault of the network element comprises the steps of S1, collecting alarm information of the network element according to a preset time period; S2, obtaining unhandled alarm information according to alarm handling zone bits; S3, grouping the unhandled alarm information according to an ID of the network element, analyzing the unhandled alarm information, and determining the type of the fault of the network element; S4, carrying out fault prejudgment based on historical fault information if the type of the fault of the network element cannot be determined, and determining the log extraction type; S5, having access to the network element according to the log extraction type to obtain logs of the network element; S6, carrying out fault analysis according to the logs of the network element, comparing the fault analysis result and the fault prejudgment result, marking the alarm handling zone bits of the alarm information to be handled if the fault analysis result and the fault prejudgment result are consistent, modifying the fault prejudgment result to be the fault analysis result if the fault analysis result and the fault prejudgment result are not consistent, and marking the alarm handling zone bits to be handled. Due to the fact that fault prejudgment is carried out on an alarm of the network element, fault removal efficiency can be improved, and manpower can be saved.

Description

technical field [0001] The present invention relates to wireless network technology, in particular to a method and device for judging network element faults. Background technique [0002] The fault analysis of network elements in the wireless network is generally performed manually through the alarm form reported by the OMC (Operation and Management center) operation and management center combined with the logs of the network elements. [0003] At present, the analysis of NE alarms generally adopts the following steps: [0004] 1. Extract network element alarms from OMC; [0005] 2. Filter the alarms according to the correlation between time and network elements, and the filtered alarms are called a group of related alarms; [0006] 3. Determine the cause of the fault according to the alarm form of the relevant alarm, if not, go to step 4; [0007] 4. Access the alarm network element; [0008] 5. Obtain network element logs; [0009] 6. Locate the cause of the fault thr...
