Problems solved by technology

The application of the judgment tree makes the analysis conclusions of each step must be mutually exclusive, that is, if the analysis conclusion A is obtained, the analysis conclusion B must be excluded, so that the judgment tree cannot be used when analyzing concurrency problems
For example, the increase in the call drop rate may be caused by various reasons such as base station carrier frequency failure, frequency interference, handover problems, and coverage problems. If a base station has carrier frequency failure and coverage problems at the same time, the application of the judgment tree can only One of the two causes of carrier failure and coverage problems is obtained
[0022] When locating the root cause of the existing network, the network performance analysis process cannot get rid of the judgment and decision-making of the network optimization operation and maintenance personnel. The analysis conclusion of each step and the next analysis content are determined by the network optimization operation and maintenance personnel. of

Embodiment Construction

[0057] First, several basic concepts involved in the embodiments of the present invention are defined. A network event refers to a specific problem in the network, a change in network resources, an adjustment of network parameters, etc. at a specific point in time and a specific location; a network fault refers to an event that affects user perception and network quality and needs to be resolved as soon as possible cyber incident.

[0058] Embodiments of the present invention firstly provide a matrix representation manner of network performance correlation. There are two ways to express the existing data correlation. One way is to use the correlation function to calculate the correlation coefficient R between two sets of data. The correlation function can only represent the correlation between two variables. The relationship between them cannot be expressed. Another way is to use multiple regression analysis to express the correlation between multiple variables through a set...

Abstract

The invention discloses a network performance analysis method and device for automatic analysis for network performance correlation. The invention also discloses a network failure positioning method and device based on network performance analysis for reducing analysis quantity for positioning network failure, promoting accuracy of positioning result. The network performance analysis method comprises: setting time range, distance range and network attribute according to network performance analysis demand; determining correlated attribute of network attribute according to network fluctuation information in distance range received in time range; establishing specimen matrix model of every network affair according to association of every network affair with related network affair to which network attribute corresponds in time range and distance range; generating network attribute matrix model according to specimen matrix model of every network affair, the matrix model is used for describing network attribute in time range and distance range and probability of occurrence of related attribute.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network performance analysis and network fault location technology. Background technique [0002] The network quality of mobile communication systems has become one of the core competitiveness of operators. In order to consolidate the network quality of the mobile communication system and improve user satisfaction, operators not only need to solve the most basic network hardware failures or alarms during the network optimization and maintenance process, but also need to monitor and analyze the fluctuations of various network performance indicators, so that Discover potential problems in the network in time, and eliminate these potential problems before affecting user perception. [0003] In the current network optimization and maintenance process, there are as many as thousands of network performance indicators available, and the relationship between various network perform...
