Description
Technical field
The present invention relates to mobile communication technology field, more particularly, to a kind of configuring method for neighboring area and system.
Background technology
At present, TD SDMA (Time Division Synchronous Code Division
Multiple, TD-SCDMA）Networking launches on a large scale, steps into ripe commercial stage.And timesharing Long Term Evolution
(Time Division Long Term Evolution, TD-LTE) network is the follow-up evolution technology of TD-SCDMA network, this
Sample one, is that cell planning configuring adjacent cell is also extremely urgent in these wireless networks, proposes TD- for this some operator
The multiband networking smooth evolution scheme of SCDMA network and TD-LTE network parallel.
Due in the physical planning allocation plan of TD-LTE network, the existing site of these TD-SCDMA network, machine room
With antenna etc., it is all scarce resource for TD-LTE network, then, from saving operator's investment, facilitate network operation
Angle considers, this two networks are necessary to the networking mode of co-sited, common cell and co-space feedback system.
Currently, TD-SCDMA network is mainly using F-band altogether to TD-LTE network smooth evolution mainstream technology
（1880MHz-1920MHz）Resource distribution mode, like this, between network, frequency difference is less, and both adopt cobasis station,
Cell, co-space feedback system, the mode of common F-band are also technically feasible altogether, although in TD-LTE network, self-organizing
SON（SelfOrganization Network）There are Neighborhood Optimization allocative abilities, but SON functionally needs in TD-LTE net
After stable operation for a period of time opened by network, just can complete the self-optimizing configuration work of adjacent area, and distribute rationally effect also with TD-
In close relations related between LTE network planning stage default adjacent area and Serving cell it can be seen that, TD-LTE network just
Phase neighbor cell configuration belongs to impassable workflow, and its allocative effect directly affects the network performance at TD-LTE network initial stage.
Further, TD-LTE network and TD-SCDMA network cobasis station, altogether cell, co-space feedback system, altogether F-band and
In the case that TD-LTE network is inter-frequency networking, because both handover mechanisms differ greatly, i.e. TD-SCDMA network switching is main
Primary Common Control Physical Channel (Primary Common Control Physical with reference to each cell and its each adjacent area
Channel, PCCPCH) received signal code power (Received Signal Code Power, RSCP) value, and TD-LTE network
The switching each cell of Primary Reference and its each adjacent area downlink reference signal receiving power ((Reference Signal Receiving
Power, RSRP) value, and terminal, when initiating switching flow, requires to there is also difference to the signal strength of both networks, because
This, in neighbor cell configuration, be difficult directly to indiscriminately imitate the Neighboring Cell List of each cell in existing TD-SCDMA network, as TD-
The Neighboring Cell List of each cell of LTE network.
So, in existing TD-LTE network, during for each cell (such as Serving cell) configuring adjacent cell, it is usually used
Emulation tool, in conjunction with coverage prediction result, then further according to the subjective experience of network planning engineer, goes to configure each little by hand
The adjacent area in area.Specifically, first meeting is first based on TD-LTE network parameter（If TD-LTE network and TD-SCDMA network antenna feeder altogether
In the case of system, these network parameters directly can adopt TD-SCDMA network parameter, for example, include longitude, the latitude of each cell
Degree, azimuth, angle of declination and F-band configuration information etc.）, electronic chart and propagation model, to predict in each TD-LTE network
The coverage of each cell；Secondly, further according to the subjective experience of network planning engineer, in conjunction with each cell in TD-LTE network
Position relationship completes the configuration of adjacent area.
The flow process of above-mentioned configuring adjacent cell, as shown in figure 1, specifically can include：
S101：According to TD-LTE network coverage simulation result, according to the overlapping relationship between each cell, generate each cell
First Neighboring Cell List, wherein, cell big for overlapping area is set to adjacent area；
S102：According to the position relationship of cell each in TD-LTE network, to the adjacent area in the first Neighboring Cell List of each cell
Carry out increasing, subtract；
Specifically, for a cell, if the cell adjacent with this cell does not configure in the first Neighboring Cell List,
Can be increased in this first Neighboring Cell List；If existing distant with this cell little in the first Neighboring Cell List
Area is it is also possible to delete from this first Neighboring Cell List.
S103：According to the result of step S101 and step S102, regenerate the second Neighboring Cell List of each cell,
As final neighboring BS relationship configuration result.
Can be seen that above-mentioned this collocation method from above-mentioned neighbor cell configuration flow process and there are following shortcomings：
1st, the method, according to TD-SCDMA network parameter, electronic chart and propagation model etc., obtains in TD-LTE network
During the coverage of each cell, may be because of the impact of some factors, such as electronic chart does not update, building layout changes
Change, propagation model precision be not high, leads to the emulation of coverage capability result obtaining not accurate enough, thus causing the neighbour of each cell configuration
Area is not accurate enough, and that is, the accuracy of configuring adjacent cell is poor.
2nd, the method needs the subjective experience according to network planning engineer, and the adjacent area of each cell is adjusted repeatedly
Whole, for example carry out the operation such as increasing and decreasing, like this, the method can only rely on manually to complete, human resourcess' consumption is larger, and
Artificial adjustment repeatedly can lead to the allocative efficiency of adjacent area low and deployment cost is high.

Specific embodiment
Based on TD-LTE network and TD-SCDMA network can with the characteristic at cobasis station, its cell, altogether antenna feeder and F-band altogether,
For, in the flow process of each cell configuration adjacent area, may not updating because of electronic chart, build in existing TD-LTE network
Build the change of thing layout, the impact of the not high factor of propagation model precision, thus leading to the accuracy of the adjacent area for this cell configuration
Poor, and existing procedure also needs to the subjective experience according to network planning engineer, comes the adjacent area to this cell configuration and carries out
Repeatedly adjust, so may result in human resourcess and consume the problem larger, allocative efficiency is low and deployment cost is high.Based on above-mentioned
Problem, embodiments provides a kind of configuring method for neighboring area and system, and the embodiment of the present invention can be by some calculations follow-up
Method flow process obtains the adjacent area of each cell in TD-LTE network, need not manpower in a large number, and switching can be gone out for this cell configuration
The higher adjacent area of probability, that is, the accuracy configuring is preferable.
TD-SCDMA network with sharing base station, cell and antenna-feedback system (first network) and TD-LTE network (below
Two networks) as a example, in conjunction with Figure of description, the concrete reality to a kind of configuring method for neighboring area provided in an embodiment of the present invention and system
The mode of applying illustrates.
Certainly, method and system provided in an embodiment of the present invention are not limited in above-mentioned both networks, are equally also suitable
In the network of other cobasis station, altogether cell and co-space feedback systems each other, its configuration flow is identical, subsequently no longer describes in detail.
A kind of configuring method for neighboring area provided in an embodiment of the present invention, as shown in Fig. 2 specifically include following steps：
S201：Rasterizing process is carried out to the first network measurement report data collecting, obtains each little in first network
The incoming level value of area's each grid in planning region；
S202：According to the incoming level value of each cell obtaining each grid in this planning region, and the second network with
The radio path propagation loss difference of first network, emulation obtains each cell each grid in this planning region in the second network
Incoming level value；
S203：For each cell in the second network and each of which adjacent area, according to this cell with this adjacent area in same grid
The incoming level value of lattice, computing terminal is switched to the switching probability value of this adjacent area from this cell；
S204：The switching probability value setting quantity is higher than the adjacent area of the neighbor cell configuration of the first given threshold as this cell.
Specifically, before execution step S201, can be from operation maintenance center (Operation Maintenance
Center, OMC) TD-SCDMA network measurement report data is gathered on equipment, such as can periodically gather from OMC equipment,
Can certainly gather by other means.
Subdistrict position area identification code (Location Area can be included in these TD-SCDMA network measurement report data
Identification, LAI), cell ID (Cell Identification, CI), subdistrict frequency point (Channel), cell
Scrambler (Cell Parameter Identifiation, CPI), location information of cell and cell incoming level value.
The position of Serving cell below, can be included in the measurement report data of this Serving cell taking a Serving cell as a example
Put area's identification code, Serving cell identification code, the PCCPCH RSCP value of Serving cell, the positional information of Serving cell, 6 adjacent areas
Frequency, the positional information of the scrambler of 6 adjacent areas, the PCCPCH RSCP value of 6 adjacent areas and 6 adjacent areas etc. is (as table 1 below institute
Show).
Table 1
Further, in above-mentioned steps S201, due to according to the TD-SCDMA network measurement report data collecting, reflecting
The sampled point being mapped to actual coverage area domain is fewer, therefore can by rasterizing process is carried out to these measurement report data,
So that the sampled point region in limited measurement report data can represent larger range of cell coverage area.
Specifically, can be divided into many using the geographic area in actual TD-SCDMA network as planning region
The individual length of side is the square grid of L, and the selection of grid length of side L for example can exist according to the different value of specific scene setting
Dense urban can be different from the value when suburb.Further, as shown in figure 3, wherein G (X, Y) is this grid center of a lattice
Coordinate, S (x, y) is the coordinate of a sampled point, and this sampled point can be the cell in TD-SCDMA network.
Next, can pass through taking one of one of TD-SCDMA network cell and planning region grid as a example
Following manner obtains in TD-SCDMA network this cell in the RSCP value of each grid：
Possibly collected in the different time periods due to the measurement report data of TD-SCDMA network, therefore, these
In measurement report data, the position coordinateses of each cell and its corresponding RSCP value etc. may be different.
Whether meet following two conditions firstly the need of all coordinates judging this cell：
Wherein, X, Y are respectively this grid center of a lattice horizontal stroke, vertical coordinate, and x, y are respectively the horizontal stroke of this cell, vertical coordinate；
Secondly, in the case of meeting, all RSCP corresponding to coordinate meeting above-mentioned condition of this cell are just calculated
Value meansigma methodss, and as this cell this grid RSCP value.In this case, TD-SCDMA network measurement report
Data is converted into data as shown in table 2 below.
Table 2
| Grid | Cell LAC | Cell CI | Grid longitude | Grid dimension | PCCPCH RSCP |
| 1 | 18748 | 26652 | 112.429 | 34.6883 | -82 |
| 1 | 18748 | 26653 | 112.429 | 34.6883 | -79 |
| 2 | ... | ... | ... | ... | ... |
In the case of ungratified, then not on this grid, that is, this cell does not have RSCP value on this grid to this cell.?
Here, for some cell in TD-SCDMA network, it is not all to correspond to a RSCP value in all grids, and
It is on the premise of meeting above-mentioned two condition, this cell just has corresponding RSCP value on this grid.
For other cells in TD-SCDMA network, obtain these cells the RSCP value on grid mode with
State the mode of obtaining identical, will not be described here.
Specifically, in above-mentioned steps S202, can be obtained each little in TD-LTE network by following manner computer sim- ulation
Area is in the RSRP value of each grid：
First, according to following formula one：
PLDELTA=26.6lgfTD-LTE network-26.6lgfTD-SCDMA network,
Wherein, fTD-LTE networkDownlink working frequency for TD-LTE network；
fTD-SCDMA networkDownlink working frequency for TD-SCDMA network；
PLDELTAPath loss correction value for TD-LTE network and TD-SCDMA network；
Calculate the path loss correction value of TD-LTE network and TD-SCDMA；
Then, by calculated PLDELTA, substitute into following formula two:
PLTDL(n)=PPccPchRSCP(Cell(sm))- Gainantenna(m)- PPccPchRSCP（n）+PLDELTA,
Wherein, PPccPchRSCP(Cell(sm))Primary common control physical for each cell in TD-SCDMA network (cell (sm))
The receipt signal code check (being the RSCP value of each cell) of channel；
Gainantenna(m)For the antenna gain at each grid central point in planning region and each cell line；
PPccPchRSCP（n）For each cell in TD-SCDMA network each grid (n be grid number) RSCP value；
PLTDL(n)For the radio path propagation loss difference of TD-LTE network and TD-SCDMA network, (i.e. signal is from TD-LTE
In network, each grid point is to the radio transmission loss value of each cell)；
The radio path propagation calculating TD-LTE network with TD-SCDMA network is lost difference;
Finally, by calculated PLTDL(n)Substitute into following formula three：
RSRP(n)=PRS_cell(m)+ Gainantenna（m）-PLTDL(n),
Wherein, PRS_cellRSRP value for each cell in TD-LTE network；
RSRP(n)(it is that each grid central point receives for each cell in TD-LTE network in the RSRP value of each grid
Each cell RSRP value);
Each cell can be calculated in TD-LTE network in the incoming level value of each grid.
It is briefly described as follows the derivation of above-mentioned formula 1：Because TD-LTE network is used with TD-SCDMA network
Different frequency ranges, so, the path loss correction value by same antenna-feedback system a to grid point is also different.Therefore, may be used
With reference to macrocellular COST231-Hata propagation model, to calculate the smooth landform in urban district for two networks respectively by following formula
Radio wave propagation loss intermediate value：
Lb=46.3+26.6log(F)-13.82log(Hb)-α(Hm)+[44.9-6.55log(Hb)]log(d)+Cm
Wherein, Lb is that the standard in urban district for the network smooths landform radio wave propagation loss intermediate value (dB)；
F is the downlink working frequency (MHz) of network；
hbFor antenna for base station effective depth (m)；
hmFor mobile portable antennas effective depth (m)；
D is mobile station and the distance between base station (Km)；
α(hm) it is mobile portable antennas height factors；
Then calculate TD-LTE network and the standard in urban district for the TD-SCDMA network smooth landform radio wave propagation loss intermediate value it
Difference, you can obtain the path loss correction value (above-mentioned formula 1) of TD-LTE network and TD-SCDMA network：
PLDELTA=LbTDL-LbTDS=26.6lgfTD-LTE network-26.6lgfTD-SCDMA network.
Further, after execution above-mentioned steps S202, each cell can be obtained in TD-LTE network in each grid
On RSRP value, so, for each grid in a cell (such as Serving cell) and planning region, it with it
There are following two kinds of situations between one adjacent area：
The first situation：Both all have RSRP value on this grid, and it is overlapping covered that both exist for this representative；
Second situation：Both have RSRP value by one on this grid, and it is overlapping covered that both do not exist for this representative.
According to above-mentioned both of these case, the embodiment of the present invention can be by calculating Serving cell with its all adjacent areas same
RSRP difference on one grid, to build interference matrix between Serving cell and its all adjacent areas (to embody Serving cell
Overlapping coverage condition with all adjacent areas), still, calculate between the two taking above-mentioned Serving cell and its adjacent area as a example
After RSRP difference (i.e. level difference), data as shown in table 3 below can be obtained.
Table 3
In TD-LTE network to be calculated, all cells and its corresponding adjacent area are after the level difference on same grid, you can
Obtain the interference matrix of each cell and its all adjacent area in TD-LTE network, as shown in table 4 below, PI, jRepresent cell i and adjacent area
Level difference (i≤the N of j；J≤N, N are natural number).
Table 4
| Adjacent area 1 | Adjacent area 2 | Adjacent area 3 | ...... | Adjacent area N | |
| Cell 1 | 0 | P12 | P13 | ...... | P1N |
| Cell 2 | P21 | 0 | P23 | ...... | P2N |
| Cell 3 | P31 | P32 | 0 | ...... | P3N |
| ...... | ...... | ...... | ...... | ...... | ...... |
| Cell N | P41 | P42 | P43 | ...... | 0 |
By each cell in above-mentioned table 4 and its adjacent area after the level difference matching of same grid, a normal state can be obtained
Distribution function (as shown in Figure 4), by this cell and other adjacent areas after level difference all matchings of same grid, can obtain multiple
Normal distyribution function.
Specifically, for one of TD-LTE network cell, this normal distyribution function can express this exactly
The distribution situation of the level difference of cell and one adjacent area, that is, abscissa represent the level difference of this cell and this adjacent area, vertical coordinate
(i.e. this cell and this adjacent area are in same grid to represent this cell grid number corresponding under a certain value with the level difference of this adjacent area
The number of lattice).This function can be determined by two variables, that is, this cell and this adjacent area same grid level difference average
Value, and the standard deviation of this cell and the level difference in same grid for this adjacent area.
Specifically, in above-mentioned steps S203, for each cell in TD-LTE network and each adjacent area, by following sides
Formula computing terminal is switched to this adjacent area switching probability value from this cell：
The same grid number that this adjacent area that the RSRP calculating value is less than the second given threshold is located, is located with this cell
Grid number carry out ratio computing, obtain the switching probability value that terminal is switched to this adjacent area from this cell.
Still it is assumed that the Second Threshold setting is as 10 taking a Serving cell and its adjacent area as a example, then, service is little
The number of the corresponding same grid being this adjacent area place in this subregion that area is less than 10 with the RSRP difference of this adjacent area (is such as schemed
Shown in 5 dashed part), only this grid number and this cell affiliated grid number need to be carried out ratio computing, you can obtain terminal from this
Cell is switched to the switching probability value of this adjacent area.
Specifically, in above-mentioned steps S204, for each cell in TD-LTE network and each of which adjacent area, for being somebody's turn to do
During cell configuration adjacent area, a number of adjacent area can be chosen at random from the adjacent area that switching probability value is higher than the first given threshold
Adjacent area as this cell；Switching probability value can also be higher than the adjacent area of the first given threshold, according to switching probability value from big
Arranged to little, selected a number of adjacent area as the adjacent area of this cell.Certainly, the embodiment of the present invention can also adopt it
The mode of his configuring adjacent cell, here is no longer enumerated one by one.
For other cells in TD-SCDMA network and its corresponding adjacent area, calculation process ibid, will not be described here.
In addition, the embodiment of the present invention except using said method for each the cell configuration adjacent area in TD-LTE network in addition to,
Can also be these cell configuration adjacent areas by following two ways：
First kind of way：For each cell belonging in TD-LTE network under a base station, outside this cell
The distance between other cells and this base station whether in setpoint distance, if it does, then these cells are directly configured
For the adjacent area of this cell, and also their highest priority can be set.
The second way：For each cell in TD-LTE network, little with this according to other cells outside this cell
Whether the distance between area is in setpoint distance, if it does, then these cells can also be directly configured to this cell
Adjacent area.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of neighbor cell configuration system, because this system is solved
Certainly the principle of problem is similar to aforementioned configuring method for neighboring area, and the enforcement of therefore this system may refer to the enforcement of preceding method, weight
