Description

A kind of method and apparatus that obtains KQI thresholding

Technical field

The invention belongs to communication technique field, relate in particular to a kind of method and apparatus of the KQI of obtaining thresholding.

Background technology

Along with the market development of telecommunications service becomes the market of sufficient competition, promoting client's user satisfaction has become the only way of possessing self client and attract rival client.Client's user satisfaction is made up of many aspects, quality of service is important component wherein, conventionally adopt Key Quality Indicator (Key Quality Index, KQI) weigh quality of service quality, KQI is the quality index based on service and application, Key Performance Indicator (Key Performance Index, KPI) is the performance index based on network element, and KQI is than be more the close to the users index of perception of KPI.

At present, the method of evaluating KQI quality is according to service level agreement (Service-level Agreement, SLA) evaluate the quality of KQI, SLA refers to the agreement about service quality of signing between user and service provider, stipulated the level that KQI need to reach, but these are only applicable to sign the client of SLA, for most of user, as a reference, the numerical value of KQI can only not served as the assessment of relative superior or inferior to SLA.

The method of the existing KQI of obtaining thresholding is that KQI and user are carried out to association analysis to the evaluation of quality of service, traditional way is in laboratory, under a fixing KQI condition, QoE is carried out to repeated measurement, then the QoE under identical conditions is averaged, obtain the average mark of the QoE under this condition, the average mark under KQI value and this condition is carried out curve fitting, obtain the quantitative relation between KQI index and QoE, the flex point of binding curve is obtained KQI thresholding.This method needs repeated measurement user satisfaction under same quality of service condition, but same quality of service condition recurrent probability in existing network is very little, and therefore this method is not suitable for finding KQI thresholding in existing network.

In addition, existing KQI is as the evaluation to overall quality of service but not individual consumer's quality of service, and KQI is the tabulate statistics based on event.Because KQI adds up based on event, that is to say 1 user occur 100 abnormal and 100 users everyone occur 1 time abnormal, existing KQI statistics is the same, obviously, from the angle of overall user awareness, latter event is larger to overall user satisfaction injury, characterizes quality of service merely with KQI, cannot effectively be mapped with user satisfaction.

Meanwhile, operator obtains and rival's competitive advantage, in quality of service field, depend on objective indicator to recently determining and optimize direction, as KQI and KPI.Directly contrast objective indicator, likely mislead and optimize direction, there are several following situations: although a certain index gap, but its value is all in being unlikely to affect the region of user satisfaction, optimizing so this index will can not bring the lifting of user satisfaction, although a certain index be in a leading position, relatively rival, having more a high proportion of user to be subject to the impact of this index, is the target that optimize on the contrary.

In sum, under existing communication network condition, need to be adapted at the standard of obtaining KQI gate method under existing communication network condition and judging KQI quality, the index of the measurement quality of service of the satisfaction of being more close to the users is provided, with the index of effect of optimization of user satisfaction as weighing user oriented group, meanwhile, operator also needs to identify crucial KQI, curstomer-oriented user satisfaction is thrown in more accurately and optimize the resource promoting.

Summary of the invention

The embodiment of the present invention provides a kind of method and apparatus of the KQI of obtaining thresholding, be intended to solve the inapplicable existing network of method of the existing KQI of obtaining thresholding, existing KQI is as the evaluation to overall quality of service, cannot limitedly be mapped with user satisfaction, existing KQI and KPI are used for determining optimization direction to being compared to client's index by operator, and existence may mislead the problem of optimizing direction.

In the present embodiment, by repeating the method for embodiment bis-, can obtain the overall service quality assessment of multiple KQI, the method for obtaining crucial KQI by overall service quality assessment is as follows:

Situation is a size for described the first overall service quality assessment of the more multiple KQI of described KQI threshold device, selects the KQI of described the first overall service quality assessment maximum, as the first crucial KQI.

Wherein, because the first crucial KQI is the KQI of user's ratio maximum more than KQI thresholding in multiple KQI, be also the KQI that is inferior to user's ratio maximum of KQI thresholding, therefore the first crucial KQI quality of service promotes, can very effective raising user satisfaction.

Another kind of situation is the size of described the second overall service quality assessment of the more multiple KQI of described KQI threshold device, selects the KQI of described the second overall service quality assessment minimum, as the second crucial KQI.

Be wherein the KQI of user's ratio minimum more than KQI thresholding in multiple KQI due to the second crucial KQI, also be the KQI that is better than user's ratio minimum of KQI thresholding, therefore the second crucial KQI quality of service room for promotion is large, optimizes this KQI and can significantly improve user satisfaction.

The embodiment of the present invention, provides a kind of method of obtaining crucial KQI, helps operator's curstomer-oriented user satisfaction, throws in more accurately and optimizes the resource promoting.
