Device Alert Association Analysis for TD Wireless Access Networks

Wireless Access networks are still quite common. So I studied the device alarm Association Analysis of TD wireless access networks. Here I will share it with you, hoping it will be useful to you. With the implementation and application of TD-SCDMA network, "how to carry out effective O & M management of complex TD-SCDMA network" has become the focus of attention of operators.

The intelligent comprehensive analysis model for TD Wireless Access networks is a subject of cooperative research and development between Putian and Hebei mobile. This topic follows the O & M model of "centralized monitoring, centralized maintenance, and centralized management" proposed by China Mobile Group Corporation to "facilitate O & M personnel to fully understand the health status of the overall network operation, monitoring, analysis and processing of network problems in a timely manner, accurate judgment of the nature and root of the problem "as a guide, for TD-SCDMA network wireless access network, A solution is proposed to automatically locate the root cause of the problem and analyze the impact of the problem based on the fault, performance, and configuration information.

Wireless Access Network in TD-SCDMA network, its network scale and equipment environment are diverse. Ptian started from TD-SCDMA Wireless Access Network and equipment, completed the device alarm association analysis, KPI degradation and alarm Association Relationship Analysis, wireless networking environment alarm impact analysis, the alarm association model, KPI downgrade alarm association model, alarm propagation impact model, and other analysis models with practical application prospects are created.

Device alarm association analysis:

Based on the data mining theory and through the analysis and test of Putian device alarms, Putian forms a mature alarm Association mining algorithm. This mining algorithm is used to mine the alarm data in the Putian outfield, forming an association between the alarms of the Putian device. At the same time, these relationships are further verified in the test environment. The alarm association model is applied to alarm Association Suppression Rules of TD-SCDMA Wireless Access Network Management System, which can effectively reduce the number of alarms handled by network management personnel. Each alarm Association processing reduces the number of handled alarms in the associated alarm set by 50%, greatly reducing the maintenance experience requirements for O & M personnel.

KPI downgrade and Alarm Correlation analysis:

The two indicators of wireless connection rate and wireless disconnection rate are the KPIs that operators are most concerned about. This topic mainly analyzes the fault model of NodeB from the perspective of affecting the wireless connection rate and the configuration of NodeB in the actual network, A correlation model is formed between KPI degradation and Node B device alarms. The association model is applied to the network management system of TD-SCDMA wireless access network, which can facilitate O & M personnel to locate the KPI downgrade alarm. The following gives a specific application scenario: OMC-R will wireless access rate downgrade to show O & M personnel, when O & M personnel want to know the reason for the downgrade, The OMC-R will automatically present the relevant alarm, this greatly simplifies the operation difficulty of O & M personnel and improves work efficiency.

Analysis of the alarm impact in the wireless networking environment of Putian:

In view of the networking mode and configuration of Putian devices in actual network applications, this paper analyzes the influence of NodeB device alarms on the propagation of TD wireless access networks, and forms an alarm propagation impact model. The impact of alarm propagation covers the following areas: the NodeB community, the neighboring areas of other Node B, and RNC. The impact of alarm propagation varies depending on the severity of the alarm: the current zone and RNC of the current Node B community and other Node B are not affected, the Community cannot be used, and the communication between RNC and Node B is affected. With this alarm propagation impact model, O & M personnel can learn the impact scope and extent through the alarm, so as to determine the priority of alarm processing.

These three analysis models can be used independently or in combination. For example, by combining the alarm propagation impact model with the alarm association model, the O & M personnel can quickly and accurately locate the fault source of the alarm, so as to solve the problem more quickly and quickly, saves operation and maintenance costs. At the same time, the three models of Putian provide some reference and value for the network maintenance of the entire TD wireless access network, and will wholeheartedly serve the operator's network maintenance and the construction of the TD boutique network.
