Problems solved by technology

Under normal circumstances, KPI indicators are extracted once a day to determine and analyze bad cells. However, when the network is busy, if a network element fails, it will lead to a decline in the service quality of individual cells or even multiple cells; if abnormal indicators cannot be found in time , will be complained by customers
After a problem occurs, analyzing network faults will consume a lot of manpower and time

Embodiment 1

[0031] Embodiment 1 of the present invention provides a fault diagnosis method. The execution subject of the method may be a network KPI intelligent diagnosis tool (short for intelligent diagnosis tool). The application scenarios of this method include but are not limited to: TD-SCDMA system, GSM (Global System for Mobile Communications (Global Mobile Communications) system, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) system, CDMA2000 (Code Division Multiple Access, Code Division Multiple Access) system, etc. Such as figure 1 As shown, the method includes the following steps:

[0032] Step 101, the intelligent diagnostic tool acquires network data. Among them, the intelligent diagnosis tool can obtain the network data from the operation and maintenance center (such as OMCR), and the network data includes but not limited to KPI index information, latitude and longitude information, parameter configuration information or any combinatio...

Embodiment 2

[0043] Embodiment 2 of the present invention provides a method for diagnosing faults. The execution subject of the method may be a network KPI intelligent diagnosis tool (smart diagnosis tool for short). In this embodiment, the figure 2 The illustrated topology diagram of the intelligent diagnosis tool in the RAN system is taken as an example for illustration.

[0044] Among them, the intelligent diagnostic tool can be deployed on the PC in the same local area network as OMCR in the operation and maintenance network, or it can be deployed on other devices. From figure 2 It can be seen that the intelligent diagnostic tool and OMCR are in the same local area network, and the intelligent diagnostic tool can directly access the database of OMCR; and the intelligent diagnostic tool can access the base station controller (RNC) and base station (NodeB) through the OMCR. By accessing the OMCR database, the intelligent diagnosis tool can extract the data of OMCR; in addition, the in...

Embodiment 3

[0070]Embodiment 3 of the present invention provides a method for diagnosing faults. The execution subject of the method may be a network KPI intelligent diagnosis tool (short for intelligent diagnosis tool). In this embodiment, a specific intelligent diagnosis process is used to illustrate the operation of the intelligent diagnosis tool. working principle.

[0071] Assuming that the operation and maintenance personnel need to diagnose the analysis conclusion of the RRC failure of the entire network from 18:00 on December 25, 2010 to 08:00 on December 26, 2010, the following tasks are performed:

[0072] 1) Configure the intelligent diagnostic tool. In this embodiment, only the RRC connection rate indicators of the entire network are diagnosed. The configuration information is as follows: Service: Diagnose service selection RRC failure (diagnoses RAB failure, call drop rate, etc., and can also diagnose all) ;Threshold: The failure threshold is configured as the number of cell ...

Abstract

The invention discloses a fault diagnosis method and fault diagnosis equipment. The method comprises the following steps of: acquiring network data; acquiring the network element data of network element equipment according to a pre-stored case script program when the network data determines that the network element equipment has a fault; and determining fault information according to the network element data and the pre-stored case script program. In an embodiment of the invention, a key performance indicator (KPI) intelligent diagnosis tool determines the fault information according to the pre-stored case script program and the network element data acquired from the network element equipment, can realize the real-time monitoring of the KPI of a radio access network (RAN) system, and can improve the efficiency of the equipment fault analysis of the RAN system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fault diagnosis method and equipment. Background technique [0002] In the current TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) wireless access network maintenance, the tools used for operation and maintenance work mainly include OMCR (Operation and Maintenance Center, Operation Administration and Maintenance Center) , LMT (Local Maintenance Terminal, local maintenance terminal), etc.; the working method is mainly to manually monitor OMCR alarms, extract network KPI (Key Performance Indicator, key performance indicators) indicators from OMCR to analyze network quality, locate network element problems, log in The network element device checks the device status, extracts the device log, and conducts manual analysis in combination with the existing device troubleshooting manual. [0003] Specifi...
