Problems solved by technology

[0007] (1) The early warning threshold is set artificially, mainly depends on the experience of maintenance personnel, and cannot change with the network situation in real time, making the early warning accuracy rate low;
[0008] (2) Without checking the validity of the abnormal data within the sampling period (that is, index values ​​that deviate from the daily average level), the sampling data is directly averaged, which will lead to the omission of hidden fault information or the generation of a large number of false early warning information , also greatly restricts the accuracy of early warning

Embodiment 1

[0020] figure 1 It is a flow chart of Embodiment 1 of the network performance early warning method of the present invention. Such as figure 1 As shown, Embodiment 1 of the network performance early warning method includes the following steps:

[0021] Step 102, collecting current network performance index data in real time;

[0022] Step 103, calculating the benchmark value of the dynamic warning threshold according to the sample space of the historical network performance index data;

[0023] The historical network performance index data can be extracted from the OMC, or stored in the network performance early warning device, such as call drop rate, congestion rate, wireless connection rate, or network-wide handover success rate, etc., and the historical network performance The index data is used as the sample space, and the current network performance index data is collected at the same time;

[0024] Since the historical network performance index data may contain data o...

Embodiment 2

[0033] Preferably, in step 104 of this embodiment, two layers of tolerance lines can be used to form a dynamic warning threshold, and plus or minus 2σ is taken as the tolerance range for general warnings, and plus or minus 3σ is taken as the tolerance range for important warnings. For performance indicators (such as call drop rate, congestion rate, etc.), the smaller the value, the better the network operation, select the upper tolerance line, μ+2σ and μ+3σ; the larger the value, the better the performance of the network operation Indicators (such as wireless connection rate, network-wide handover success rate, etc.), select the tolerance line μ-2σ and μ-3σ below it.

[0034] In this embodiment, the dynamic warning threshold is set through the "3σ" rule of the normal distribution theory. The warning threshold is not a fixed value set artificially, but changes in real time. The setting of the dynamic early warning threshold makes the judgment of abnormal network performance mor...

Embodiment 3

[0036] More preferably, in step 104, the dynamic early warning threshold can be divided into multiple levels, corresponding to different early warning levels:

[0037] 1. For example, classify the dynamic warning thresholds according to the warning levels of "important (yellow)" and "general (blue)". When the network performance index is higher than the upper tolerance line μ+2σ, but lower than μ+3σ (or lower than the lower tolerance line μ-2σ, but higher than μ-3σ), the "general (blue)" warning level is adopted; when When the network performance index is higher than the upper tolerance line μ+3σ or lower than the lower tolerance line μ-3σ, the “yellow (important)” warning level is adopted.

[0038] 2. Further set the two-level static warning thresholds of "red (emergency)" and "orange (serious)", that is, set the evaluation values ​​of various performance indicators in the operator's management requirements for network operation as the static thresholds for serious warnings, ...

Abstract

The invention discloses a method and device for carrying out early warning on network performance. The method for carrying out early warning on network performance comprises the following steps: collecting current network performance index data in real time; calculating the reference value of the dynamic early warning threshold according to the sample space of history network performance index data; confirming the dynamic early warning threshold according to the reference value of the dynamic early warning threshold; comparing the collected current network performance index data with the dynamic early warning threshold and carrying out early warning when the current network performance index data is not within the range of the dynamic early warning threshold. In the invention, the dynamicearly warning threshold is set by collecting the history network performance index data and real-time monitoring is carried out on the network performance according to the dynamic threshold, so that the early warning threshold changes according to the network conditions, which improves the accuracy of early warning.

Description

technical field [0001] The invention relates to a wireless technology, in particular to a network performance early warning method and device. Background technique [0002] Mobile operators implement quantitative analysis of network operation indicators by collecting, managing and analyzing counters in Operation Maintenance Centers (OMCs) of various equipment manufacturers. Each counter in the OMC communicates with network elements such as the Mobile Switching Center (MSC for short), the Base Station Controller (BSC for short), and the Home Location Register (HLR for short) in the GSM device. Certain events are related, that is, the occurrence of an event will trigger the corresponding counter to count up. [0003] The current monitoring methods for network performance generally adopt the following two methods: [0004] 1. After a network failure occurs, manually extract the statistical data on the OMC, and analyze the failure based on the failure phenomenon and combined w...
