LTE is by 3GPP (The 3rd Generation Partnership Project, third generation affiliate meter
Draw) UMTS (Universal Mobile Telecommunications System, the universal mobile communications system that organize to set up
System) technical standard long term evolution.LTE system introduces OFDM (Orthogonal Frequency Division
Multiplexing, orthogonal frequency division multiplexing) and the keys such as MIMO (Multi-Input&Multi-Output, multiple-input and multiple-output)
Technology significantly increases spectrum efficiency and message transmission rate；It supports various bandwidth distribution, and supports global mainstream 2G (the
Two generation mobile communication technical specifications)/3G (second generation mobile communication technical specification) frequency range and some newly-increased frequency ranges, thus frequency spectrum point

Type whether accurately and completely, when MR adopt several quality it is too low when will affect PCI interference total value accuracy, be unfavorable for assessment turn over PCI
The superiority and inferiority of scheme；
(2) though MR height of sampling accurately and completely, the interference model of foundation completely and network actual environment symbol with still
PCI interference value, which promotes amplitude promotion, represents the promotion of the whole network overall quality, however failing the road network quality that representative is paid close attention to is
No promotion turns over PCI scheme and is entirely possible to reach the promotion of the whole network quality by sacrificing road network quality；
(3) when calculating PCI interference total value, at present there is no a unified standard, there is respective secret in each producer
Algorithm, so the PCI interference total value calculated is not consistent, it is not comparable that the PCI interference value that each producer obtains promotes amplitude
Property, by the promotion amplitude of PCI interference value can not clearly be promoted amplitude reach how much can be implemented.

As shown in Figure 1, in a kind of LTE network Physical Cell Identifier appraisal procedure, comprising steps of
S110, before the PCI of some frequency point updates in frequency sweep data, frequency point described in each sampled point is obtained respectively
Second signal intensity corresponding 2nd PCI of corresponding first PCI of first strongest signal strength and the frequency point, described first
The difference of strongest signal strength and the second signal intensity is within a preset range；
S120, to frequency point described in frequency sweep data PCI update after, obtain frequency point described in each sampled point respectively
Corresponding 4th PCI of fourth signal intensity of corresponding 3rd PCI of third strongest signal strength and the frequency point, the third
The difference of strongest signal strength and the fourth signal intensity is in the preset range；
S130, the first mod conflict sampled point, root in all sampled points are obtained according to the first PCI and the 2nd PCI
The 2nd mod conflict sampled point in all sampled points is obtained according to the 3rd PCI and the 4th PCI；
S140, conflict according to the first mod conflict sampled point with the ratio of total sampled point and the 2nd mod sampling
The difference of point and the ratio of total sampled point obtains mod conflict promotion ratio；
S150, amplitude is promoted according to the PCI interference value of the frequency point after MR data acquisition PCI update；
S160, the promotion ratio that conflicted according to the mod and the PCI interference value promote amplitude and assess updated PCI phase
Than the superiority and inferiority of the PCI before update.
In step S110 and step S120, PCI is updated, PCI is carried out to turn over frequency.It is accurate in view of assessment
Property, need by stages to assess PCI scheme is turned over.So in one embodiment, being obtained described in each sampled point respectively
The step of second signal intensity of frequency point corresponding two PCI may include:
S1101, in each sampled point, the determining difference with the first strongest signal strength is less than the first preset threshold respectively
First time signal strength, and it is strong less than second of signal of the second preset threshold with the difference of the first strongest signal strength
Degree, first preset threshold are less than second preset threshold；
If the strongest signal strength of some sampled point intermediate-frequeney point is less than certain value, illustrate that the signal of the sampled point is strong
Degree is too weak, can directly abandon the sampled point.So in one embodiment, first strongest signal strength is greater than pre-
If signal strength threshold.Preset signal strength threshold value can be set to -110dBm (decibel milli X) etc..
First preset threshold and the second preset threshold can determine according to actual needs, such as can be by the first preset threshold
It is set as 3dB, sets 6dB for the second preset threshold.First time signal strength and second of signal strength are only used for difference
Unlike signal intensity in binary signal intensity.
S1102, the acquisition corresponding first time PCI of first time signal strength and second of signal strength are corresponding
Second of PCI；
First time PCI and second of PCI is only used for PCI different in the 2nd PCI of difference.It can be direct according to frequency sweep data
Obtain first time signal strength corresponding PCI and the corresponding PCI of second of signal strength.
Equally, in one embodiment, the fourth signal intensity for obtaining frequency point described in each sampled point respectively is corresponding
The step of four PCI may include:
S1201, in each sampled point, it is default to be less than described first for the determining difference with third strongest signal strength respectively

Third time PCI and the 4th PCI is only used for PCI different in the 4th PCI of difference.It can be direct according to frequency sweep data
Obtain corresponding PCI and the 4th corresponding PCI of signal strength of third time signal strength.
Although the present invention is done not to this it should be noted that above-mentioned carried out example to the case where two sections
It limits out.For example, user can find PCI corresponding with the signal strength in strongest signal strength difference 3dB, can also find
The corresponding PCI of signal strength in 3dB and in 6dB is differed with strongest signal strength, can also look for strong with peak signal
The corresponding PCI of signal strength in degree difference 3dB, in 6dB and 9dB.In order to guarantee the efficiency and accuracy of assessment, this
PCI in invention preferably two sections of searching, such as the signal that searching is differed with strongest signal strength in 3dB and in 6dB are strong
Spend corresponding PCI.
The process for obtaining PCI for a better understanding of the present invention, is illustrated below with reference to a specific frequency sweep data.
As shown in table 1, a part of data for the frequency sweep data surveyed before updating for PCI, H are classified as the signal strength of frequency sweep.
Each sampled point can be obtained according to time and longitude and latitude, as shown in table 1, there is sampled point 1 and sampled point 2 the two sampled points.
Updating to the PCI of certain frequency point keeps other data in table constant, is updated to the corresponding PCI of the frequency point in E column.
By taking frequency point 38400 as an example, strongest signal strength of the frequency point in sampled point 1 is -95.94dBm, and it is strong to meet signal
Degree is greater than -110dBm, and corresponding PCI value is 137.The signal strength of homogeneous-frequency adjacent-domain in strongest signal strength 3dB be-
The corresponding PCI of 98.43dBm, -98.43dBm is 374.
1 PCI of table updates preceding part frequency sweep data
In step s 130, mod conflict sampled point generally comprise mod3 conflict sampled point, mod6 conflict sampled point and
Mod30 conflict sampled point in any one or more etc..Mod3 conflict is mod (PCI1,3)=mod (PCI2,3)；Mod6 punching
Prominent i.e. mod (PCI1,6)=mod (PCI2,6)；Mod30 conflict is mod (PCI1,30)=mod (PCI2,30).First mod punching
The conflict vertex type of prominent sampled point conflict with the 2nd mod sampled point conflict vertex type it is generally identical, i.e., if the first of acquisition
Mod conflicts sampled point for mod3 conflict sampled point, then the 2nd mod conflict sampled point equally obtained is also mod3 conflict sampling
Point.
Since mod3 conflict generally can accurate description road quality, it is possible to obtain mod3 in all sampled points and rush
Prominent sampled point.In order to more accurately assess, it is also possible to obtain mod3 conflict sampled point and mod6 conflict sampling in all sampled points
Point, or mod3 conflict sampled point in all sampled points, mod6 conflict sampled point and mod30 conflict sampled point are obtained simultaneously,
The present invention makes restriction not to this.
In one embodiment, the first mod in all sampled points is obtained according to the first PCI and the 2nd PCI to rush
The step of prominent sampled point may include:
First time mod in all sampled points is obtained according to the first PCI and the first time PCI to conflict sampled point；
Second of mod in all sampled points is obtained according to the first PCI and second of PCI to conflict sampled point.
In one embodiment, the 2nd mod in all sampled points is obtained according to the 3rd PCI and the 4th PCI to rush
The step of prominent sampled point may include:
Third time mod in all sampled points is obtained according to the 3rd PCI and the third time PCI to conflict sampled point；
The 4th mod in all sampled points is obtained according to the 3rd PCI and the 4th PCI to conflict sampled point.
By taking the PCI in mod3 conflict and table 1 in strongest signal strength 3dB as an example, due to Mod (137,3)=Mod (374,
3), the sampled point so mod that sampled point 1 is 3dB conflicts.The method for obtaining the mod conflict sampled point of 6dB is similar, refuses herein
It repeats.
In step S140, in one embodiment, according to the ratio of the first mod conflict sampled point and total sampled point
And the difference of the ratio of the 2nd mod conflict sampled point and total sampled point, the step of obtaining mod conflict promotion ratio
May include:
Conflicted according to first time mod conflict sampled point with the ratio of total sampled point and the third time mod
The difference of the ratio of sampled point and total sampled point obtains first time mod conflict promotion ratio；
Conflicted according to second of mod conflict sampled point with the ratio of total sampled point and the 4th mod
The difference of the ratio of sampled point and total sampled point obtains second of mod conflict promotion ratio.

In step S150, the PCI interference value promotion for turning over PCI scheme can be obtained according to existing mode in the prior art
Amplitude obtains PCI interference value according to following expressions and promotes amplitude:
PCI interferes total value to be based on MR data and is obtained by interference coefficient and co-frequency cell related coefficient.
In step S160, the superiority and inferiority that PCI scheme is turned in assessment assesses whether turn over PCI scheme implementable.It, can in assessment
To detect whether mod conflict promotion ratio meets corresponding condition, PCI interference value promotes whether amplitude meets corresponding condition,
If be all satisfied, illustrate that the PCI updated can be implemented, it can the optimization for turn over PCI is promoted, and otherwise, is needed to region
Network carries out turning over PCI optimization promotion again after carrying out structure optimization.Due to needing comprehensive mod conflict promotion ratio and PCI interference value
Promotion amplitude is assessed, so i.e. consider road quality has taken into account the whole network quality to the present invention again, obtained PCI scheme of turning over is
The first-class scheme of real meaning.
In view of the scheme in order to assess accuracy and by stages implementation, in one embodiment, conflicted according to the mod
Promotion ratio and the PCI interference value promote the step of amplitude assesses superiority and inferiority of the updated PCI compared to the PCI before update can

(3) mod30 conflict promotion ratio reaches third preset ratio or more, such as 35%.
(4) the total interference value of PCI promotes amplitude greater than the 4th preset ratio, such as 20%.
If what is calculated is mod3 conflict promotion ratio, judge that mod3 conflict promotion ratio and the total interference value of PCI promote width
Whether degree meets respective condition.If what is calculated is mod3 conflict promotion ratio and mod6 conflict promotion ratio, mod3 is judged
Conflict promotion ratio, mod6 conflict promotion ratio and the total interference value of PCI promote whether amplitude meets respective condition.If calculated
Be mod3 conflict promotion ratio, mod6 conflict promotion ratio and mod30 conflict promotion ratio, judge mod3 conflict promoted ratio
Example, mod6 conflict promotion ratio, mod30 conflict promotion ratio and the total interference value of PCI promote whether amplitude meets respective condition.
Other situations are similar, not example one by one.
In order to better understand above-mentioned evaluation condition, below to consider that mod3 conflict promotion ratio, mod6 conflict promote ratio
Example, mod30 conflict for promotion ratio and by stages (such as 3dB and 6dB), are described in detail.
