104, calculate the topology fraction of each candidate sector according to the orientation weighted value and the number of plies with respect to first sector;

After the orientation weighted value and the number of plies between first sector and each candidate sector confirmed between first sector and each candidate sector; First sector of confirming in the integrating step 102 again and the distance between each candidate sector can be calculated the topology fraction of each candidate sector with respect to first sector.

105, according to topology fraction with the candidate sector of correspondence adjacent area as first sector.

After having calculated the topology fraction of each candidate sector, can sort to these topology fraction, and the corresponding candidate sector of the topology fraction after will sorting adds the Neighboring Cell List of first sector with respect to first sector.

In the present embodiment; Can obtain the network topology parameter of each sector; And confirm candidate sector according to this network topology parameter, and calculate orientation weighted value and the number of plies between first sector and each candidate sector between first sector and each candidate sector simultaneously, finally confirm the adjacent area of first sector according to these parameters; Because the network topology parameter generally can be is directly acquired according to the engineering parameter table of existing network; So when carrying out adjacent section planning, need not to re-use high-precision numerical map, thereby can improve adjacent section planning speed, and reduce the adjacent section planning cost.

For ease of understanding, below the adjacent section planning method in the embodiment of the invention is divided into two processes and describes:

One, choose the candidate sector process:

See also Fig. 2, in the embodiment of the invention, when carrying out adjacent section planning, the process of choosing candidate sector comprises:

201, select a sector as current sector SectorA;

202, judge whether current sector need plan the adjacent area, if need, then execution in step 203, if do not need, then execution in step 210;

After having confirmed current sector SectorA (i.e. first sector), can judge whether this sector need plan the adjacent area, and the process of judgement is those skilled in the art's a common practise, repeats no more here.

203, travel through all the other sector SectorB;

If confirm and need plan the adjacent area to SectorA, then the sector SectorB (i.e. second sector) to other travels through.

204, the distance B istance between calculating SectorA and the SectorB;

Confirm after SectorA and the SectorB, then can obtain the engineering parameter table that presets from the base station, and according to the longitude and latitude in this network topology parameter, or other can identify the calculation of parameter SectorA in geographical position and the distance between the SectorB.

205, whether distance is 0, if then execution in step 208, if not, then execution in step 206;

After the distance that calculates between SectorA and the SectorB, can judge whether this distance is 0, if 0, then execution in step 208, if be not 0, then execution in step 206.

206, whether distance is greater than ultimate range, if then execution in step 209, if not, then execution in step 207;

Preset a ultimate range in the present embodiment, if the distance between SectorB and the SectorA surpasses this ultimate range, then SectorB can not become the adjacent area of SectorA.

207, N position before whether distance comes, if then execution in step 208, if not, then execution in step 209;

Need to prove; If the distance between SectorA and the SectorB is not more than ultimate range; Explaining that then SectorB possibly become the adjacent area of SectorA, then write down the distance between SectorA and the SectorB, specifically can be to deposit the distance between SectorA and the SectorB in interim tabulation.

After repeatedly traveling through; Should then may have a plurality of distances in the interim tabulation, the distance in this interim tabulation is arranged according to order from small to large, when the corresponding distance of SectorB deposits this interim tabulation in; Can judge whether this distance comes top n; If do not come top n, represent that then SectorB also can not become the adjacent area of SectorA, this N is the maximum adjacent area number of SectorA.

208, the candidate adjacent tabulation that SectorB is added SectorA;

If the distance between SectorA and the SectorB is 0, then showing between these two sectors has intersection, or the next-door neighbour, therefore can promptly add the candidate adjacent tabulation of SectorA directly with the candidate sector of SectorB as SectorA.

If the distance between SectorA and the SectorB comes top n in interim tabulation, then can the candidate sector of SectorB as SectorA promptly be added the candidate adjacent tabulation of SectorA equally.

209, judge whether traversal is accomplished, if do not accomplish, then execution in step 203, if accomplish, then execution in step 210;

In the present embodiment, greater than ultimate range, then SectorB can not then travel through next pending sector as the adjacent area of SectorA as if the distance between SectorA and the SectorB.

N position before if the distance between SectorA and the SectorB does not come in interim tabulation, then SectorB also can not be as the adjacent area of SectorA, the next pending sector of same traversal.

210, finish.

When SectorA need not plan the adjacent area, or all SectorB have all traveled through after the completion, then process ends.

In the present embodiment; Promptly chosen the candidate sector of SectorA through the network topology parameter; Promptly set up the candidate adjacent tabulation of SectorA, the sector in this candidate adjacent tabulation all is the sector that is expected to become the adjacent area of SectorA, then gets ready for follow-up further screening and ordering.

Two, confirm the process of adjacent area:

See also Fig. 3, in the embodiment of the invention, when carrying out adjacent section planning, confirm that the process of the adjacent area of first sector comprises:

301, obtain the candidate adjacent tabulation of current sector SectorA;

In the present embodiment,, then can directly get access to this candidate adjacent tabulation here because the candidate adjacent tabulation of SectorA (i.e. first sector) has been set up in the front.

302, each candidate sector SectorB is got in the tabulation of traversal candidate adjacent;

303, the orientation weighted value between calculating SectorA and the SectorB;

In the present embodiment, can be according to the orientation weighted value between network topology calculation of parameter SectorA and the SectorB:

See also Fig. 4, wherein, website A can represent the center of the first sector SectorA, and website B can represent the center of candidate sector SectorB, then the computational process of the orientation weighted value between SectorA and the SectorB can for:

Obtain line between the center of center and SectorB of SectorA with respect to first angle in the positive north of SectorA and this line with respect to the positive second northern angle of SectorB;

According to first angle and second angle obtain this line with respect to azimuthal the 3rd angle of SectorA and this line with respect to azimuthal the 4th angle of SectorB;

Calculate the orientation weighted value of SectorB according to the horizontal half-power of the antenna of the 3rd angle and SectorA with respect to SectorA;

Calculate the orientation weighted value of SectorA according to the horizontal half-power of the antenna of the 4th angle and SectorB with respect to SectorB.

Need to prove; Only with the center of the center of SectorA and SectorB end points, it is understandable that, in practical application in the present embodiment as line; If website A is positioned at other positions of SectorA; And/or website B is positioned at other positions of SectorB, too can be with website A and website B end points as line, and the center of center and SectorB that is not limited to only to adopt SectorA is as the end points of line.

Concrete account form sees also Fig. 4:

AD is a dotted line of vertical and direct north.When calculating, ignore the ground ball, be thought of as the calculating on the two dimensional surface.

The concrete computational process of first angle: the longitude and latitude that known A, B are ordered, Δ Long are the difference of longitude of 2 of AB, equal the longitude that B orders and deduct the longitude that A is ordered, and Δ Lat is the difference of latitude of 2 of AB, equal the latitude that B orders and deduct the difference of latitude that A is ordered.

If Δ Long equal 0 and Δ Lat more than or equal to 0, then angle DAB equal 0 the degree;

If Δ Long equal 0 and Δ Lat less than 0, then angle DAB equal 180 the degree;

If Δ Lat equal 0 and Δ Long greater than 0, then angle DAB equal 90 the degree;

If Δ Lat equal 0 and Δ Long less than 0, then angle DAB equal 270 the degree;

If Δ Lat greater than 0 and Δ Long greater than 0, then angle DAB equals Atan (Δ Long/ Δ Lat) * 180/Pi;

If Δ Lat less than 0 and Δ Long greater than 0, then angle DAB equals 180+Atan (Δ Long/ Δ Lat) * 180/Pi;

If Δ Lat greater than 0 and Δ Long less than 0, then angle DAB equals 360+Atan (Δ Long/ Δ Lat) * 180/Pi;

If Δ Lat less than 0 and Δ Long less than 0, then angle DAB equals 180+Atan (Δ Long/ Δ Lat) * 180/Pi.

Angle DAB adds the number of degrees that 90 degree promptly obtain first angle.

Second angle calculates with first angle similar, just when calculating the longitude and latitude difference, A, B is exchanged.

The computational process of the 3rd angle: spend if the difference at the azimuth of first angle and A is less than or equal to 180, then the 3rd angle equals azimuth poor of first angle and A.If the difference at the azimuth of first angle and A is spent more than or equal to-180, then the 3rd angle equals azimuth poor of 360+ first angle and A.

The computational process of the 4th angle: spend if the difference at the azimuth of second angle and B is less than or equal to 180, then the 4th angle equals azimuth poor of second angle and B.If the difference at the azimuth of second angle and B is spent more than or equal to-180, then the 4th angle equals azimuth poor of 360+ second angle and A.

The computational process of orientation weighted value is:

Antenna horizontal directivity pattern (being the horizontal half-power of antenna) according to the 3rd angle and SectorA calculates the orientation weighted value of SectorB with respect to SectorA; In the antenna horizontal directivity pattern of SectorA, find the yield value corresponding with the 3rd angle; SectorB equals 10^ (yield value/35) with respect to the orientation weighted value of SectorA.

Antenna horizontal directivity pattern (being the horizontal half-power of antenna) according to the 4th angle and SectorB calculates the orientation weighted value of SectorA with respect to SectorB.In the antenna horizontal directivity pattern of SectorB, find the yield value corresponding with the 4th angle; SectorA equals 10^ (yield value/35) with respect to the orientation weighted value of SectorB.

Orientation weighted value DiffAngle (k) between SectorA and the SectorB equals SectorB with respect to orientation weighted value+SectorA of SectorA orientation weighted value with respect to SectorB.

Need to prove that if SectorB is indoor website, SectorA is outdoor website, then SectorB equates with respect to the orientation weighted value of SectorB with SectorA with respect to the orientation weighted value of SectorA.

304, the number of plies between calculating SectorA and the SectorB;

See also Fig. 5, in the present embodiment, angle FAE is an angle threshold value, and by parameter setting, wherein the AB line is the axis of angle FAE.The number of plies between SectorA and the SectorB is meant to falling into the sector number in the triangle FAE zone.When calculating the number of plies of SectorA and SectorB, adopt following mode:

Suppose SectorC; SectorD .... be other sector, judge whether to fall into delta-shaped region? At first calculate the distance of SectorA and SectorC (all other sectors); Obtain sector SectorC, and then calculate the included angle B AC of AC and AB formation less than the AB distance.If the BAC angle is less than or equal to the half the of threshold value FAE, represent that then SectorC has fallen into this Delta Region, number of plies statistics+1.Otherwise, also can calculate angle earlier, computed range also can be realized again.

Need to prove:

If SectorB is outdoor sector, then with the number of the outdoor sector that comprises in the Delta Region as the number of plies between SectorA and the SectorB;

If SectorB is indoor sector, then with the number of outdoor sector that comprises in the Delta Region and indoor sector as the number of plies between SectorA and the SectorB.

Except adopting above-mentioned mode to calculate the number of plies between SectorA and the SectorB, can also adopt other mode, for example:

With the line between SectorA and the SectorB as border circular areas of diameter structure, with the number that drops on the sector in this border circular areas as the number of plies between SectorA and the SectorB.

In the present embodiment, the sequencing of not carrying out between the step 303 and 304 can carry out 303 earlier, also can carry out 304 earlier, perhaps also can carry out simultaneously, does not limit here.

305, calculate the topology fraction of SectorB to SectorA;

In the present embodiment; After having calculated the orientation weighted value and the number of plies between SectorA and the SectorB between SectorA and the SectorB through step 303 and 304; Combine the distance between SectorA and the SectorB can calculate the topology fraction of SectorB again, specifically can calculate through following formula to SectorA:

If SectorB is outdoor sector, then SectorB with respect to the topology fraction Score (k) of SectorA is:

$\mathrm{Score}\left(k\right)=\frac{\mathrm{Dists}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{Dists}\left(k\right)}\×\frac{\mathrm{DiffAngle}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{DiffAngle}\left(k\right)}\×\frac{\mathrm{dLayer}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{dLayer}\left(k\right)}$

If SectorB is indoor sector, then SectorB with respect to the topology fraction Score (k) of SectorA is:

$\mathrm{Score}\left(k\right)=\frac{\mathrm{Dists}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{Dists}\left(k\right)}\×\frac{\mathrm{DiffAngle}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{DiffAngle}\left(k\right)}\×\frac{\mathrm{dLayer}\left(k\right)}{\underset{k=1}{\overset{\mathrm{MAX}\_\mathrm{DIS}\_\mathrm{SEC}}{\mathrm{\Σ}}}\mathrm{dLayer}\left(k\right)}\×Z$

Wherein, Dists (k) is the distance between SectorB and the SectorA, and MAX DIS SEC is the total number of candidate sector, and DiffAngle (k) is the orientation weighted value between SectorA and the SectorB; DLayer (k) is the number of plies between SectorA and the SectorB; Z is the power difference of outdoor sector and indoor sector, and in the present embodiment, Z can be 10 ^10/35, in practical application, the concrete numerical value of this Z also maybe be different, do not limit here.

306, judge whether traversal is accomplished, if then execution in step 307, if not, then execution in step 302;

307, ordering generates Neighboring Cell List.

If all candidate sector in the candidate adjacent tabulation have all been carried out aforesaid operations; Then can the topology fraction of each candidate sector be sorted; Sort according to mark order from small to large, and successively each candidate sector is added the Neighboring Cell List of SectorA according to the order after this ordering.

In the present embodiment; After having confirmed candidate sector; Can be according to the number of plies between the orientation weighted value between network topology calculation of parameter first sector and each candidate sector and first sector and each candidate sector; Finally confirm the adjacent area of first sector, because the network topology parameter generally can be directly acquire according to the engineering parameter table of existing network, so when carrying out adjacent section planning, need not to re-use high-precision numerical map according to these parameters; Thereby can improve adjacent section planning speed, and reduce the adjacent section planning cost.
