Advantage of the present invention is included in this specification, protects within the scope of the present invention and by following claim.This partial content should be understood as to limitations on claims.Below in conjunction with accompanying drawing, the further aspect of the present invention and advantage are discussed.It is all exemplary and explanat should understanding generality description and detailed description below above of the present invention, is intended to provide of the present invention the further illustrating to claimed.
Accompanying drawing explanation
Fig. 1 is according to the flow chart of the carrier frequency static power regulation method based on measurement report of a specific embodiment of the present invention.
Embodiment
Based on problems of the prior art, the present invention proposes the carrier frequency static power regulation method based on measurement report (hereinafter to be referred as MR).First carry out the whole network carrier frequency static power rational assessment is set, according to assessment result, automatically adjust carrier frequency static power, replace the work of a large amount of customary drive tests, fixed test and manual analysis community Key Performance Indicator, saved O&M cost.And with MR, assess and adjust carrier frequency static power, more targeted than drive test and one-point measurement, more accurate than manual analysis, more effective, the cycle is shorter, more can embody the true environment of network.
Below with reference to the accompanying drawings the carrier frequency static power regulation method based on measurement report is introduced.
The present invention, by gathering the MR in the certain hour of community, analyzes the covering of community, the Key Performance Indicators such as signal quality, and the foundation using the Key Performance Indicator of MR statistics as carrier frequency static power assessment, provides a kind of carrier frequency static power appraisal procedure based on MR.Set the thresholding that carrier frequency power is adjusted simultaneously, comprise and reduce carrier frequency static power thresholding and improve carrier frequency static power thresholding, according to the relatively more definite community that need to carry out power adjustment of assessment result and respective threshold.
The operation principle of the method is as follows:
1, the extraction to measurement report
Within certain cycle, extract the measurement report of community some, the community of wherein extracting measurement report is the scope Nei community that user-defined carrier frequency static power is adjusted.
2, the assessment to carrier frequency static power
Key Performance Indicator as carrier frequency static power assessment foundation in measurement report should comprise: cover class index and quality indicator, wherein cover class index and comprise face coverage rate; Quality indicator comprises downlink quality and the mistake coverage rate of community, and it specifically can be: face coverage rate, downlink quality are better than the ratio of certain thresholding and cross coverage rate, but are not limited to this three kinds of indexs.
The present invention defines carrier frequency static power evaluate parameter M as the standard of carrier frequency static power assessment, carrier frequency static power evaluate parameter is defined as carrier frequency static power evaluate parameter=covering class index * covering weight+quality indicator * quality weight, wherein covers weight+quality weight=100%.
3, the adjustment to carrier frequency static power
The present invention proposes the concept that carrier frequency static power reduces thresholding and carrier frequency static power lifting thresholding, be defined as follows:

Carrier frequency static power promotes thresholding: cell carrier frequencies static power evaluate parameter is during lower than this thresholding, and Cai Dui community reduces carrier frequency static power.
User can reduce thresholding and carrier frequency static power lifting thresholding according to the actual conditions of network and user's oneself standard setting carrier frequency static power.
According to the assessment result of carrier frequency static power, the community that cell carrier frequencies static power evaluate parameter is reduced to thresholding higher than carrier frequency static power sends the request of reduction carrier frequency static power; The community that cell carrier frequencies static power evaluate parameter is promoted to thresholding lower than carrier frequency static power sends the carrier frequency static power request that promotes.
4, table tennis testing mechanism
The invention allows for table tennis testing mechanism: for sending continuously and alternately the community that reduces carrier frequency static power adjustment request and promote carrier frequency static power adjustment request, or for sending continuously and alternately the community that promotes carrier frequency static power adjustment request and reduce carrier frequency static power adjustment request, the carrier frequency static power of community is set as to power setting corresponding to maximum carrier frequency static power evaluate parameter value, to avoid the too low weak covering phenomenon causing of power setting of ping-pong phenomenon small area, Jiang Gai community adds table tennis blacklist simultaneously, forbid within a certain period of time the static power adjustment of this community.
The step-length of carrier frequency static power adjustment is set to adjust a step-length (being 2dB) at every turn.According to the difference of producer, rate of static power may be different, but all by every next step-length, adjust, and maximum power does not send the request of lifting, do not send and reduce request during minimum power.
Carrier frequency static power promotes or reduces all carrier frequency in Jun Dui community and operates.
Repeat above process, the carrier frequency static power of dynamic community adjusting.
With reference to parameter as shown in the table, the carrier frequency static power regulation method based on measurement report according to one embodiment of the present invention is described in detail.
