Embodiment
Describe below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is plot planning processing method implementing procedure sketch map, and is as shown in the figure, when the sub-district is planned, can comprise the steps:
Step 102, according to bunch in subdistrict position relation said subdistrict frequency point resource and code source are planned;
Enforcement in the face of each step describes down.
Through the sub-clustering of step 101, the notion of in the plot planning of TD-SCDMA system, having introduced bunch.In the enforcement, at first define the size of a cell cluster, then the frequency and the code word of sub-district in the definition bunch respectively; Bunch size can define according to desirable micro-honeycomb structure, such as 7,19,37......; Can confirm according to certain recurrence formula, also can artificially define bunch size of arbitrary number; The definition of subdistrict frequency point code word also can artificially define setting in bunch, also can calculate according to traditional planning algorithm.
After in the plot planning of TD-SCDMA system, introducing bunch; Overcome because of TD-SCDMA system existing frequency planning sign indicating number planning calculating unified distribution on the basis of the whole network; Because it is a variety of that the principle of foundation has, and cause final program results from figure, also not have rule, short and sweet deficiency not directly perceived.
In the enforcement, when sub-clustering is carried out in the sub-district, may further include:
Making bunch becomes a level honeycomb that spreads towards periphery with center cell.
Fig. 2 be bunch in the annular level honeycomb sketch map of sub-district; As shown in the figure; Be that a 3-tier architecture figure who spreads towards periphery with center cell describes among the figure; Be not limited in 3 layers in the practical implementation, the relation between sub-district number and the level is: if the definition center cell is a ground floor, then the sub-district number scale is a
n, n ∈ N, n representes the number of plies; The sub-district number and the number of plies satisfy:
a
1＝1，a
n+1＝a
n+6*n，n＝1，2，3......。
There is above-mentioned relation to be prone to know a
1=1, a
2=7, a
3=19, a
4=37, a
5=61, a
6=91, a
7=127......
Fig. 3 be bunch in the cell structure sketch map, as shown in the figure, the sub-district is a regular hexagon, then for a desirable honeycomb, can be defined as follows several distances:
R=2R
C,
Wherein: r is the clover radius of society, R
CBe central point distance to the limit, R is the distance of central point to the limit.
Can know in conjunction with Fig. 2 and Fig. 3, be for the multiplex distance of 128 scramblers:
The cell cluster number of plies is 7 o'clock, a
7=127, minimum multiplex distance is 9R
C, i.e. 4.5r.
For 32 downlink frequency pilot code multiplex distances be:
Suppose that dominant frequency point number is M, then equivalent downlink frequency pilot code number is 32 * M, finds the n value to make M satisfy formula a
n＜32*M＜a
N+1, then downlink frequency pilot code can be supported n layer cell cluster.
If n is an odd number: multiplex distance is Rc*3 (n-1)/2; N=1,3,5.....
Annotate: long arrow has marked the direction of calculating multiplexing radius among Fig. 2.
If n is an even number: multiplex distance approximates Rc*3 (n-1)/2 for thinking, especially when the n value is big, n=2,4,6....
Annotate: the short-and-medium arrow of Fig. 2 has marked the direction of the multiplexing radius of calculating when n=4.
What calculate among the embodiment is the multiplex distance of desirable honeycomb; In real network, because more than 6 of the adjacent area of a sub-district, so top multiplex distance will shorten, in practical implementation, this need adjust according to actual conditions.
Through above-mentioned bunch and bunch in the explanation of sub-district, can find out in step 101 pair sub-district and carry out sub-clustering, and during the sub-district number in confirming bunch, bunch cell size determine jointly by planning dominant frequency point number, 32 downlink frequency pilot code, 128 scramblers.Thereby make in step 102, can make and in one bunch, downlink frequency pilot code and dominant frequency point are planned together that scrambler can not repeat simultaneously, thereby cell code planning does not repeat in having guaranteed bunch.Because the frequency of TD-SCDMA system is all very limited with the sign indicating number resource, thus the planning of sub-clustering frequency planning sign indicating number is incorporated into come among the TD-SCDMA after, overcome TD-SCDMA and compared, system's frequency resource-constrained with GSM; Compare with WCDMA, the shortcoming of sign indicating number resource-constrained can reach the maximized purpose of TD sign indicating number multiplex distance.
Step 102 according to bunch in the enforcement that said subdistrict frequency point resource and code source are planned of subdistrict position relation in; After the sub-district number in confirming bunch, bunch cell size determine jointly by planning dominant frequency point number, 32 downlink frequency pilot code, 128 scramblers.Concrete, the sub-district number in all sub-districts of TD-SCDMA system in by said bunch, and frequency resource and code source when planning can comprise:
M=min (P * k, (128-m)), wherein:
Comprise N sub-district in the TD-SCDMA system, then bunch sub-district is M, and it is m that the user reserves the scrambler number, and downlink frequency pilot code is P, and dominant frequency point number is k.
Describe below.
1), codeword reserved:
Can be provided with and whether give user's codeword reserved; If reserve, the user can own selection wants the code word reserved.Codeword reserved is not used when bunch plot planning, mainly is used for leaving for not planning that sub-district, newly-increased sub-district use, and the cause user is artificial as required in the enforcement is provided with.
2), bunch cell code planning:
Suppose that planning dominant frequency point number is k, it is m that the user reserves the scrambler number, and the planning sub-district adds up to N, and downlink frequency pilot code is P, and then equivalent available downlink frequency pilot code is P * k.
Find the solution M=min (P * k, (128-m)); With N microzonation sub-clustering sub-district, bunch cell size is M, divides with nearby principle according to cell topology, if N can not be divided exactly by M, remainder constitutes last bunch, and it is individual that the such number that must fall bunch rounds (N/M) on being.Nearby principle is meant when realizing, is reference with bunch center cell, according to GIS-Geographic Information System by direct north counterclockwise from the close-by examples to those far off, the microzonation of counting to bunch size is divided into one bunch.Certainly, nearby principle only is a kind of execution mode, its objective is the actual conditions that are to combine the whole network sub-district, and the sub-district by bunch dividing, is divided each bunch of back and formed structure shown in Figure 2, all can adopt as long as can realize the execution mode of this purpose.
Then frequency and sign indicating number planning are carried out in bunch sub-district.K dominant frequency point and P pilot code are reconfigured; Constitute unduplicated equivalent downlink frequency pilot code; Give a bunch sub-district assignment equivalence downlink frequency pilot code, select scrambler according to pilot code information to the user, the compound key restriction can be considered according to the sign indicating number planning principles of reality in a plurality of sub-districts of same website.Because bunch size is M=min (P * k, (128-m)), thus can obtain that frequency, downlink frequency pilot code, scrambler make rational planning for bunch.A bunch program results is copied in other bunches,, only duplicate a part of program results of wherein corresponding size and get final product for last less bunch.
Know from above-mentioned, when bunch plot planning, after given dominant frequency point planning number, codeword reserved, bunch size just definite with program results.Need to prove that when carrying out the planning of frequency resource and code source, existing planning mode also can adopt.
