Embodiment 1

[0032] refer to figure 2 , shows a flow chart of steps of a network problem analysis method according to Embodiment 1 of the present invention.

[0033] The steps of the network problem analysis method in this embodiment are as follows:

[0034] Step S202: Use a script program to determine the N cells with the worst key performance indicators causing network problems; wherein, N is a natural number greater than or equal to 1.

[0035] At present, the KPIs concerned by TD-LTE system network optimization mainly include the following categories: access index, retention index, mobility index, traffic index and network resource index. Through the detection of KPI indicators of the system, it is possible to: identify unexpected problems in network performance; early warning of risks such as network failures and network quality degradation; ensure the stability of network KPI indicators and the gradual improvement of network performance and quality. The specific KPI indicators cor...

Embodiment 2

[0048] refer to image 3 , shows a flow chart of steps of a network problem analysis method according to Embodiment 2 of the present invention.

[0049] The specific steps of the network problem analysis method in this embodiment are as follows:

[0050] Step S302: Use a script program to determine N cells with the worst key performance indicators causing network problems; wherein, N is a natural number greater than or equal to 1.

[0051] It should be noted that the purpose of determining the N cells with the worst key performance indicators that cause network problems is to use these N cells as the analysis object to analyze the service interaction between the terminal side and the network side in the N cells Message data, analyze the abnormal business and the cause of the abnormal business from the business interaction message data. The number N of cells can be appropriately set by those skilled in the art according to requirements, and can be one or any appropriate numbe...

Embodiment 3

[0073] refer to Figure 4 , shows a flow chart of steps of a network problem analysis method according to Embodiment 3 of the present invention.

[0074] The specific steps of the network problem analysis method in this embodiment are as follows:

[0075] Step S402: Determine relevant KPI indicators.

[0076] Based on the current status of the network, network optimization personnel determine the key issues to be concerned about, and then determine the relevant KPI indicators. For example: if it is in the early stage of station construction, the network optimization work may pay more attention to the connection between the terminal and the base station, then the access index, retention index and mobility index category will be determined as the key analysis objects, and the above categories will be determined accordingly The indicators include specific KPI indicators, such as: RRC establishment success rate, E-RAB establishment success rate, wireless connection rate, wireles...

Abstract

The invention provides a network problem analyzing method and a network problem analyzing device. The network problem analyzing method includes the steps that N cells having the poorest key performance indexes and generating network problems are determined with a script program, wherein N is a natural number larger than or equal to 1; service interaction information data corresponding to the key performance indexes in the N cells are obtained with the script program, and the service interaction information data are stored to be N CDL files corresponding to the N cells; a CDL analyzing tool is called by the script program to analyze the service interaction information data stored in the N CDL files, and abnormal services in the N CDL files are determined; the abnormal services are analyzed according to a set rule, and causes of the abnormal services are determined. With the network problem analyzing method and the network problem analyzing device, the work objectives for fast improving the network performance and the network quality of the network optimizing work are achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a network problem analysis method and device. Background technique [0002] Network quality is the lifeline of network operations, and basic network optimization is the core of improving network quality. With the gradual completion of the network construction of 15 TD-LTE (Time Division Long Term Evolution) network-scale test network cities across the country, the network optimization work of test network cities of various scales is also being actively carried out. [0003] The extraction and analysis of KPI (Key Performance Indicator, key performance indicator) is the top priority in network optimization. The KPIs concerned by the TD-LTE system mainly include the following categories: access indicators, retention indicators, mobility indicators, traffic indicators, and network resource utilization indicators. Through the monitoring of the KPI indicators of the c...
