Step S008: whether judge above-mentioned distance B 1 and distance B 2 all less than the outer shroud distance threshold value T3 that presets, if, execution in step S009 then; Otherwise, execution in step S010;
Second number of rings H2 that above-mentioned outer shroud distance threshold value T3 equals to preset and the product of above-mentioned ring spacing δ, that is:
T3＝H2*δ
Step S009: there are not district's covering more in above-mentioned cell-of-origin and Target cell, finish;
Step S010: judge that above-mentioned distance B 1 and above-mentioned distance B 2 and above-mentioned outer shroud distance threshold value T3 reach the size of preset interior ring distance threshold value T4; Promptly judge the size of D1, D2 and T3, T4; If above-mentioned distance B 1 and above-mentioned distance B 2 are all greater than above-mentioned outer shroud distance threshold value T3; Be D1＞T3, D2＞T3, then execution in step S011; If above-mentioned distance B 1 greater than above-mentioned outer shroud distance threshold value T3 above-mentioned distance B 2 less than above-mentioned outer shroud distance threshold value T4, i.e. D1＞T3, D2＜T4, then execution in step S012; If above-mentioned distance B 1 less than above-mentioned outer shroud distance threshold value T3 above-mentioned distance B 2 greater than above-mentioned outer shroud distance threshold value T3, i.e. D1＜T3, D2＞T3, then execution in step S013;
The 3rd number of rings H3 that ring distance threshold value T4 equals to preset in above-mentioned and the product of above-mentioned ring spacing δ, that is:
