Description

A kind of configuring method for neighboring area and system
Technical field
The present invention relates to mobile communication technology field, relate in particular 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, progressively enters 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, so, in these wireless networks, be that cell planning configuring adjacent cell is also extremely urgent, some operators propose the multiband networking smooth evolution scheme of TD-SCDMA network and TD-LTE network parallel for this reason.
Due in the physical planning allocation plan of TD-LTE network, these existing sites of TD-SCDMA network, machine room and antenna etc., it for TD-LTE network, is all scarce resource, so, from saving operator's investment, facilitating the angle of network operation to consider, these two networks are necessary to adopt the networking mode of common station, altogether community and co-space feedback system.
Current, TD-SCDMA network is mainly to adopt the resource distribution mode of F-band (1880MHz-1920MHz) altogether to TD-LTE network smooth evolution mainstream technology, like this, between network, frequency difference is less, and both adopt cobasis station, community altogether, co-space feedback system, the mode of F-band is also feasible technically altogether, although in TD-LTE network, self-organizing SON(SelfOrganization Network) there is Neighborhood Optimization allocative abilities, but need to be after TD-LTE network opening stable operation a period of time in SON function, just can complete the self-optimizing configuration effort of adjacent area, and distribute rationally effect also to default adjacent area of TD-LTE network planning stage and Serving cell between in close relations relevant, as can be seen here, the initial stage neighbor cell configuration of TD-LTE network belongs to impassable workflow, its allocative effect directly affects the network performance at TD-LTE network initial stage.
Further, at TD-LTE network and TD-SCDMA network cobasis station, community altogether, co-space feedback system, F-band and TD-LTE network are in the situation of inter-frequency networking altogether, because both handover mechanisms differ greatly, , TD-SCDMA network switches main Primary Common Control Physical Channel (the Primary Common Control Physical Channel with reference to Yu Qige adjacent area, each community, PCCPCH) received signal code power (Received Signal Code Power, RSCP) value, and TD-LTE network switches main reference Yu Qige adjacent area, each community downlink reference signal received power ((Reference Signal Receiving Power, RSRP) value, and terminal is in the time initiating switching flow, the signal strength of both networks is required also to there are differences, therefore, in the time of neighbor cell configuration, be difficult for directly indiscriminately imitating the Neighboring Cell List of existing TD-SCDMA network Zhong Ge community, set it as the Neighboring Cell List of TD-LTE network Ge community.
So, in existing TD-LTE network, for example, during for configuring adjacent cell, each community (Serving cell), conventionally use emulation tool, in conjunction with coverage prediction result, and then according to network planning engineer's subjective experience, the adjacent area of each community of manual configure.Particularly, first can be first based on TD-LTE network parameter (if in the situation of TD-LTE network and TD-SCDMA network co-space feedback system, these network parameters can directly adopt TD-SCDMA network parameter, for example comprise longitude, latitude, azimuth, angle of declination and the F-band configuration information etc. of each community), electronic chart and propagation model, predict the coverage of each TD-LTE network Zhong Ge community; Next, then according to network planning engineer's subjective experience, complete the configuration of adjacent area in conjunction with the position relationship of TD-LTE network Zhong Ge community.
The flow process of above-mentioned configuring adjacent cell, as shown in Figure 1, specifically can comprise:
S101: according to TD-LTE network coverage simulation result, according to the overlapping relationship between each community, generate the first Neighboring Cell List of each community, wherein, overlapping area great community is set to adjacent area;
S102: according to the position relationship of TD-LTE network Zhong Ge community, the adjacent area in the first Neighboring Cell List of Dui Ge community increases, subtracts;
Particularly, for Yi Ge community, if adjacent community, Yu Gai community is not configured in the first Neighboring Cell List, can be increased in this first Neighboring Cell List; If there is distant community, Yu Gai community in the first Neighboring Cell List, also can from this first Neighboring Cell List, delete.
S103: according to the result of step S101 and step S102, regenerate the second Neighboring Cell List of each community, as final neighboring BS relationship configuration result.
Can find out from above-mentioned neighbor cell configuration flow process, there is following shortcoming in above-mentioned this collocation method:
1, the method is according to TD-SCDMA network parameter, electronic chart and propagation model etc., while obtaining the coverage of TD-LTE network Zhong Ge community, may be because of the impact of some factors, for example electronic chart does not upgrade, building layout changes, propagation model precision is not high, cause the emulation of coverage capability result that obtains not accurate enough, thereby the adjacent area that causes each cell configuration is not accurate enough, the accuracy of configuring adjacent cell is poor.
2, the method need to be according to network planning engineer's subjective experience, adjacent area to each community is adjusted repeatedly, the operation such as for example increase and decrease, like this, the method can only rely on manually and complete, human resources consumption is larger, and the allocative efficiency that artificial adjustment repeatedly can cause adjacent area is low high with deployment cost.

Embodiment
Can cobasis station based on TD-LTE network and TD-SCDMA network, its community, antenna feeder and the altogether characteristic of F-band altogether, in existing TD-LTE network, be in the flow process of each cell configuration adjacent area, may not upgrade because of electronic chart, building layout changes, propagation model precision is the impact of high factor not, thereby cause for the accuracy of the adjacent area of this cell configuration poor, and existing procedure also needs according to network planning engineer's subjective experience, adjacent area to this cell configuration is adjusted repeatedly, will cause like this human resources consumption larger, the problem that allocative efficiency is low and deployment cost is high.Based on the problems referred to above, the embodiment of the present invention provides a kind of configuring method for neighboring area and system, the embodiment of the present invention can obtain by follow-up algorithm flows the adjacent area of each community in TD-LTE network, without a large amount of manpowers, and can go out the adjacent area that switching probability is higher for this cell configuration, the accuracy of configuration is better.
Below take the TD-SCDMA network (first network) of sharing base station, community and antenna-feedback system and TD-LTE network (second network) as example, in conjunction with Figure of description, a kind of configuring method for neighboring area that the embodiment of the present invention is provided and the embodiment of system describe.
Certainly, the method and system that the embodiment of the present invention provides are not limited in above-mentioned these two kinds of networks, are equally also applicable to other networks of cobasis station, altogether community and co-space feedback system each other, and its configuration flow is identical, follow-up no longer detailed description.
A kind of configuring method for neighboring area that the embodiment of the present invention provides, as shown in Figure 2, specifically comprises the following steps:
S201: the first network measurement report data collecting is carried out to rasterizing processing, obtain the incoming level value of first network Zhong Ge community each grid in planning region;
S202: according to the incoming level value that obtains Ge community each grid in this planning region, with the wireless path propagation loss difference of second network and first network, emulation obtains the incoming level value of second network Zhong Ge community each grid in this planning region;
S203: for the adjacent area each with it, each community in second network, the incoming level value according to Yu Gai adjacent area, this community at same grid, computing terminal Cong Gai community is switched to the switching probability value of this adjacent area;
S204: will set the switching probability value of quantity higher than the adjacent area of the neighbor cell configuration Wei Gai community of the first setting threshold.

Further, in above-mentioned steps S201, due to according to the TD-SCDMA network measure report data that collects, the sampled point that is mapped to actual coverage area territory is fewer, therefore can be by these measurement report data are carried out to rasterizing processing, so that the sampled point region in limited measurement report data can represent wider cell coverage area.
Specifically, can be using the geographic area in actual TD-SCDMA network as planning region, be divided into the square grid that multiple length of sides are L, the value that the selection of grid length of side L can be different according to concrete scene setting, for example can be different from the value when the suburb in dense urban.Further, as shown in Figure 3, the centre coordinate that wherein G (X, Y) is this grid, S (x, y) is the coordinate of a sampled point, this sampled point can be TD-SCDMA network Zhong community.
Next, take Yi Ge community in TD-SCDMA network and planning, a grid in region is as example, can obtain TD-SCDMA network Zhong Gai community in the RSCP of each grid value by following manner:
Because the measurement report data of TD-SCDMA network may be to collect in the different time periods, therefore, in these measurement report data, the position coordinates of each community and corresponding RSCP value thereof wait possible difference.
First need all coordinates that judge this community whether to meet following two conditions:
X - 1 2 L ≤ x ≤ X + 1 2 L
Y - 1 2 L ≤ y ≤ Y + 1 2 L
Wherein, X, Y are respectively this grid center of a lattice horizontal stroke, ordinate, and x, y are respectively horizontal stroke, the ordinate of this community;
Secondly,, satisfied in the situation that, just calculate the mean value of all corresponding RSCP values of coordinate that meet above-mentioned condition of this community, and set it as this community in the RSCP of this grid value.In this case, TD-SCDMA network measure report data is just converted into data as shown in table 2 below.
Table 2
Grid Community LAC Community 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 ungratified situation, Ze Gai community is not on this grid, and Ji Gai community does not have RSCP value on this grid.Here, for the some communities in TD-SCDMA network, it is not in all corresponding RSCP values of all grids, but is meeting under the prerequisite of above-mentioned two conditions, and just there is corresponding RSCP value this community on this grid.
For other communities in TD-SCDMA network, the mode that obtains the RSCP value of these communities on grid, with above-mentioned to obtain mode identical, does not repeat them here.
Particularly, in above-mentioned steps S202, can calculate emulation by following manner and obtain TD-LTE network Zhong Ge community in the RSRP of each grid value:
First, according to following formula one:
PL dELTA=26.6lgf tD-LTE network-26.6lgf tD-SCDMA network,
Wherein, f tD-LTE networkfor the downlink working frequency of TD-LTE network;
F tD-SCDMA networkfor the downlink working frequency of TD-SCDMA network;
PL dELTAfor the path loss correction value of TD-LTE network and TD-SCDMA network;
Calculate the path loss correction value of TD-LTE network and TD-SCDMA;
Then, by calculate PL dELTA, the following formula two of substitution:
PL TDL(n)＝P PccPchRSCP(Cell(sm))－Gain antenna(m)－P PccPchRSCP（n）+PL DELTA，
Wherein, P pccPchRSCP (Cell (sm))for the received signal code rate (being the RSCP value of each community) of the Primary Common Control Physical Channel of each community in TD-SCDMA network (cell (sm));
Gain antenna (m)for the antenna gain value at each grid central point and line place, each community in planning region;
P pccPchRSCP(n)for each community in TD-SCDMA network is in the RSCP value of each grid (n is grid number);
PL tDL (n)for the wireless path propagation loss difference of TD-LTE network and TD-SCDMA network (be signal from TD-LTE network each grid point to the radio transmission loss value of each community);
Calculate the wireless path propagation loss difference of TD-LTE network and TD-SCDMA network;
Finally, by the PL calculating tDL (n)the following formula three of substitution:
RSRP (n)＝P RS_cell(m)＋Gain antenna（m）-PL TDL(n)，
Wherein, P rS_ cellfor the RSRP value of each community in TD-LTE network;
RSRP (n)for each community in TD-LTE network is the RSRP of each grid value (being the RSRP value of each community of receiving of each grid central point);
Can calculate in TD-LTE network each community in the incoming level value of each grid.
The brief description derivation of above-mentioned formula 1 once below: because TD-LTE network uses different frequency ranges from TD-SCDMA network, so, also different by the path loss correction value of same antenna-feedback system to grid point.Therefore, can, with reference to macrocellular COST231-Hata propagation model, calculate respectively the level and smooth landform radio wave propagation loss intermediate value of two networks in urban district by following formula:
Lb=46.3+26.6log(F)-13.82log(H b)-α(H m)+[44.9-6.55log(H b)]log(d)+C m
Wherein, Lb is the standard of network in urban district level and smooth landform radio wave propagation loss intermediate value (dB);
F is the downlink working frequency (MHz) of network;
H bfor antenna for base station effective depth (m);
H mfor mobile portable antennas effective depth (m);
D is the distance (Km) between travelling carriage and base station;
α (h m) be mobile portable antennas height factors;
Then calculate the poor of TD-LTE network and the level and smooth landform radio wave propagation loss of the standard of TD-SCDMA network in urban district intermediate value, can obtain the path loss correction value (above-mentioned formula 1) of TD-LTE network and TD-SCDMA network:
PL dELTA=Lb tDL-Lb tDS=26.6lgf tD-LTE network-26.6lgf tD-SCDMA network.
Further, after carrying out above-mentioned steps S202, can obtain the RSRP value of each community on each grid in TD-LTE network, so, for example, for the each grid in Yi Ge community (Serving cell) and planning region, between it and it a adjacent area, there are following two kinds of situations:
The first situation: both all have RSRP value on this grid, it is overlapping covered that this represents that both exist;
The second situation: both one have RSRP value on this grid, it is overlapping covered that this represents that both do not exist.
According to above-mentioned both of these case, the embodiment of the present invention can be passed through calculation services community and its all adjacent areas RSRP difference on same grid, build the interference matrix (to embody the overlapping coverage condition of Serving cell and all adjacent areas) between Serving cell and its all adjacent areas, still take an adjacent area of above-mentioned Serving cell and it as example, calculate after RSRP difference (being level difference) between the two, can obtain data as shown in table 3 below.
Table 3
Figure BDA00002435886600111
In TD-LTE network to be calculated, after the level difference of the adjacent area of all communities and correspondence thereof on same grid, can obtain the interference matrix of adjacent areas all with it, each community in TD-LTE network, as shown in table 4 below, P i, jrepresent level difference (i≤N of cell i and adjacent area j; J≤N, N is natural number).
Table 4
? Adjacent area 1 Adjacent area 2 Adjacent area 3 ...... Adjacent area N
Community 1 0 P12 P13 ...... P1N
Community 2 P21 0 P23 ...... P2N
Community 3 P31 P32 0 ...... P3N
...... ...... ...... ...... ...... ......
Community N P41 P42 P43 ...... 0
By Yu Qi adjacent area, each community in above-mentioned table 4 after the level difference matching of same grid, can obtain a normal distyribution function (as shown in Figure 4), Jiang Gai community and other adjacent areas all after matching, can obtain multiple normal distyribution functions in the level difference of same grid.
Particularly, for Yi Ge community in TD-LTE network, this normal distyribution function can be expressed the distribution situation of the level difference of this community and an one adjacent area exactly, be the level difference that abscissa represents Yu Gai adjacent area, this community, ordinate represents level difference corresponding grid number (Yu Gai adjacent area, Ji Gai community is in the number of same grid) under a certain value of Yu Gai adjacent area, this community.This function can be decided by two variablees, and Yu Gai adjacent area, Ji Gai community is at the mean value of the level difference of same grid, and Yu Gai adjacent area, He Gai community is in the standard deviation of the level difference of same grid.
Particularly, in above-mentioned steps S203, for each community in TD-LTE network and each adjacent area, be switched to this adjacent area switching probability value by following manner computing terminal Cong Gai community:
The same grid number that the RSRP value calculating is less than to this place, adjacent area of the second setting threshold, the grid number at place, Yu Gai community carries out ratio computing, obtains terminal Cong Gai community and be switched to the switching probability value of this adjacent area.
Still take an adjacent area of a Serving cell and it as example, suppose that the Second Threshold of setting is 10, so, the RSRP difference of Yu Gai adjacent area, Serving cell be less than this part region of 10 corresponding be the number (as Fig. 5 rules as shown in part) of the same grid at this place, adjacent area, only grid number under this grid Shuo Yugai community need be carried out to ratio computing, can obtain terminal Cong Gai community and be switched to the switching probability value of this adjacent area.
Particularly, in above-mentioned steps S204, for the each community in TD-LTE network and each adjacent area thereof, in the time being this cell configuration adjacent area, can the adjacent area higher than the first setting threshold, choose at random the adjacent area of some from switching probability value as the adjacent area of this community; Also can be by switching probability value the adjacent area higher than the first setting threshold, arrange from big to small according to switching probability value, select the adjacent area of some as the adjacent area of this community.Certainly, the embodiment of the present invention also can adopt the mode of other configuring adjacent cells, enumerates no longer one by one at this.
For other communities in TD-SCDMA network and corresponding adjacent area thereof, calculation process is the same, does not repeat them here.
In addition, the embodiment of the present invention, except using said method for the each cell configuration adjacent area in TD-LTE network, can also be these cell configuration adjacent areas by following two kinds of modes:
First kind of way: for the each community belonging in TD-LTE network under a base station, according to the distance between the Yu Gai base station, other communities outside this community whether in setpoint distance, if words, these communities are directly configured to the adjacent area of this community, and it is the highest that their priority can be set.
The second way: for the each community in TD-LTE network, according to the distance between the Yu Gai community, other communities outside this community whether in setpoint distance, if also these communities directly can be configured to the adjacent area of this community.
Based on same inventive concept, the embodiment of the present invention also provides a kind of neighbor cell configuration system, because the principle that this system is dealt with problems is similar to aforementioned configuring method for neighboring area, therefore the enforcement of this system can be referring to the enforcement of preceding method, repeats part and repeat no more.
