Problems solved by technology

[0010] 1. The above-mentioned existing technical solutions can only locate the call abnormality caused by the wireless network, but when the cause of the call abnormality is the failure of the equipment in the network, the above-mentioned technical solution cannot locate the real problem
For example: when the air interface signal is not good or the success rate of access is low due to the failure of the equipment transmission or the equipment flashing off, the above technical solution cannot locate the cause of the abnormality according to the CHR. At this time, it will consume a lot of manpower and material resources Drive test to locate the problem
However, the final positioning results found that it was not the problem of the wireless network, but the problem of the equipment. On the one hand, it required a lot of manpower and material resources. On the other hand, it made it di

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0041] The causes of abnormal calls can be roughly divided into two types: wireless network reasons and device reasons. As mentioned above, abnormal call information will be recorded in the CHR data. CHR data can reflect the abnormal call caused by the wireless network, and provide relevant analysis basis for the abnormal call analysis; The information is recorded in the alarm data.

[0042] For known call abnormality (for example: user's complaint), the technical scheme that the embodiment of the present invention provides is: when utilizing CHR data and can't locate the cause of calling abnormality, determine the sub-district that the user is in when call abnormality occurs by CHR data; Determine which interface configuration objects are configured b...

Abstract

The embodiment of the invention discloses a nethod for analysing abnormal call, at first, according to the call historical record (CHR) data, the method ascertains the cell of the user when the abnormal call happens; then processes the alarm analysis for the alarm data which is generated by an interface allocation object of the base station in the adjacent time sections or abnormal call happens, positions the reason of abnormal call. The embodiment of the invention discloses a abnormal call analysing device, two methods of preventing the abnormal call and two devices thereof. The invention can improve analysis efficiency of analysing abnormal call.

Description

technical field [0001] The invention relates to a call processing technology in wireless communication, in particular to a method for analyzing abnormal calls, a device for analyzing abnormal calls, a method for preventing abnormal calls and a device for preventing abnormal calls. Background technique [0002] Mobile network users will complain to the operator when encountering abnormal situations such as call drop or access failure during the use of mobile services. In order to improve the service quality, operators always respond to users' complaints in the first time, inform users of the reasons for abnormalities, and solve problems existing in the network according to the reasons, so as to avoid abnormalities from occurring again. In the prior art, there is a technical solution for abnormal call analysis based on call history records (CHR), which roughly includes the following steps: [0003] Step 1: Record the terminal number of the complaining user, the time when the ...
