The wireless network parameter collocation method of the present invention is described in detail with reference to specific embodiment：
Exist in same panel region the two of alien frequencies throw the net G1 and G2 when, wherein network G 1 to ensure based on continuous covering,
Frequency range is H1；Network G 2 is based on absorptive capacity, and frequency range is H2.Network G 2 is generally set to high priority, network
G1 is set to low priority, can so ensure that network G 2 can receive user terminal in hot spot region and can reduce user as far as possible
Terminal thrown the net two between gravity treatment or switching.
In technical scheme, user terminal approaches uniformity in the same panel region is distributed, and network G 1 and G2 are removed
Outside frequency range is different, other works ginseng is basically identical.Specifically, wireless network parameter collocation method of the invention includes following step
Suddenly：
Step S1：Network G 1 is carried out to draw in the net to test, first RSRP of the panel region under the frequency range H1 of network G 1 is obtained
CDF curves；
Step S2：The frequency range H1 of network G 1 and the frequency range H2 of network G 2 are inputted, frequency range is calculated by cost-231 models
H1 and frequency range H2 propagation loss difference, subtracts the propagation loss difference using the first obtained RSRP CDF curves and obtains frequency range
The 2nd RSRP CDF curves under H2；
The calculation formula of cost-231 models is as follows：
Lurban=46.3+33.9log (fMHz)-13.82log(hBS)-A(hmobile)
+(44.9-6.55log(hBS))log(dkm)+CM(dB)
Wherein LurbanFor the permission path loss under frequency range, because the base station of two frequency ranges is co-sited construction and transmission power is phase
With, therefore compare the permission path loss L that the received signal strength at same position compares two frequency rangesurban, due to its dependent variable
It can offset, the frequency range H1 and frequency range H2 propagation loss difference finally obtained is 33.9log H1-33.9log H2.
Step S3：The served user terminals ratio for determining network G 2 and network G 1 is A：B, it is generally the case that due to network G 2
Based on absorptive capacity, therefore A ＞ B；
Step S4：Network G 1 and network G 2 are compared according to identified user terminal and carry out reselecting parameters and handoff parameter
Configuration, wherein table 1 are the equipping rules of reselecting parameters, and table 2 is the equipping rules of handoff parameter.
As shown in table 1, when user terminal is in the cell under frequency range H2, the cell is high priority and it is desirable that the cell
The user terminal number of A/ (A+B) * 100% in the panel region can be shared, as user terminal measurement to this cell (i.e. above-mentioned frequency range H2
Under cell) RSRP be higher than less than the RSRP of threshServingLow and alien frequencies adjacent area (i.e. cell under frequency range H1)
During thresX-Low, user terminal may exit the cell under the cell reselection to frequency range H1 under frequency range H2.
Accordingly, it would be desirable to which the value for comparing threshServingLow and thresX-Low according to the user terminal of determination is set
Put.Specifically, threshServingLow value is set to the 2nd RSRP CDF B/ (A+B) * 100%, i.e. the 2nd RSRP CDF
Curve correspondence B/ (A+B) * 100% value, what the user terminal measurement that the cell under frequency range H2 has A/ (A+B) * 100% was arrived
RSRP is higher than this numerical value；ThresX-Low value is set to the first RSRP CDF x%, i.e. the first RSRP CDF curves correspondence
X% value, the RSRP that the user terminal measurement that representing the cell under frequency range H1 has (100-x) % is arrived is higher than this numerical value.Its
In, x value can be adjusted according to actual conditions, and x span is 3-8, it is preferable that x value is 5.
When user terminal is in the cell under frequency range H1, the cell is low priority and it is desirable that the cell can share the piece
B/ (A+B) * 100% user terminal number in region, if for high priority cell user terminal measurement to alien frequencies adjacent area (i.e.
Cell under frequency range H2) RSRP be higher than thresX-High, then user terminal can leave cell reselection under frequency range H1 to frequency range
Cell under H2.
Accordingly, it would be desirable to which the value for comparing thresX-High according to the user terminal of determination is configured.Specifically, will
ThresX-High value is set to the first RSRP CDF B/ (A+B) * 100%, i.e. the first RSRP CDF curves correspondence B/ (A+B) *
100% value, the RSRP that the user terminal measurement that representing the cell under frequency range H1 has A/ (A+B) * 100% is arrived is higher than this number
Value.
The reselecting parameters equipping rules of table 1
It is consistent in order that user terminal is perceived when in connected state and Idle state, in user terminal from high priority
Using A2+A5 events, (i.e. the RSRP of this cell starts alien frequencies when being less than A2thresh and surveyed when cell is switched to low priority cell
Amount, when this cell RSRP is less than A5Thresh1, adjacent area RSRP triggers alien frequencies when meeting certain time requirement higher than A5thresh2
Switching)；When user terminal is switched to high priority cell from low priority cell using A2+A4 events (i.e. this cell
RSRP starts different-frequency measure when being less than A2thresh, adjacent area RSRP triggers alien frequencies when meeting certain time requirement higher than A4thresh
Switching).
The handoff parameter equipping rules of table 2
Wherein, the A5Thresh1 values ydB low compared with reselecting parameters threshServingLow in handoff parameter configuration, 2<y<
5, preferably y value takes 3, and this is in order to avoid immediately and being switched after the firm gravity treatment of user terminal to this cell initiation business.
Other specification value sets to set with reselecting parameters value and is consistent.
Step S5：The reselecting parameters and handoff parameter of configuration are issued to the eNB (base station) in the panel region；
Step S6：Reselecting parameters and handoff parameter are being issued to after eNB, two network users terminal ratios in observation preset time
Webmaster statistics, without adjusting if two actual network users terminals are consistent than the two network users terminal ratios with initial setting up
It is whole, terminate flow；Illustrate that user terminal in the panel region and non-uniform Distribution, then needs two to setting if not being consistent
Network users terminal ratio is adjusted, and turns to step S7；
Step S7：A, B value are reset, and the S4-S6 that repeats the above steps.
Illustrate the technique effect of the present invention so that network G 1 uses frequency range D using frequency range F, network G 2 as an example below.Such as Fig. 3 institutes
The CDF curves based on F-band and the CDF curves based on D frequency ranges are shown as, propagates and damages under non-line-of-sight propagation environment, between F/D frequency ranges
Consumption difference can be calculated by cost-231 models：Propagation loss difference=33.9log (F/D)=33.9log (2.6/1.9)
=4.6dB.From figure 3, it can be seen that in identical CDF percentages, F/D frequency range CDF curves differences (4dB) are with passing through theoretical calculation
F/D frequency range propagation loss differences it is basically identical, by predicting D frequency ranges based on F-band CDF curves and F/D propagation losses difference
CDF curves it is feasible.
It is capacity frequency range to set D frequency ranges (during high priority), it is contemplated that 60% user terminal is in D frequency ranges, 40% user
Terminal is in F-band, i.e. A：B=6：4.Then reselecting parameters set as follows：
D->During F, the D frequency ranges RSRP that user terminal is measured is less than -90dBm, when F-band RSRP is higher than -102dBm, user
Terminal reselects to cell under F-band；
F->During D, the D frequency ranges RSRP that user terminal is measured is higher than -86dBm, then reselects to cell under D frequency ranges.
In the statistical result actually obtained, 60.75% user terminal is accounted in D frequency ranges, and 39.25% user terminal is accounted for
On F-band, it is consistent substantially with the result of parameter setting.
The embodiment of the present invention draws in the net data and distribution when user terminal is uniformly distributed in Double-level Reticulated according to monolayer net
Ratio carries out the gravity treatment of two nets and the setting of handover parameter values, to realize the two network users terminals when system is without using load balancing
