608e, according to after each division under preset number combination cell RRU set in RRU home subscriber Number, the smallest combination of home subscriber number difference between cell after network scheduling controller selection division.
Due under the scene that more RRU are total to cell, the interface-free resources of each RRU be it is the same, the embodiment of the present invention with The home subscriber number of each RRU identifies the load condition of each RRU.
For each combination in the preset number combination, under the combination, cell after division Between the calculation of home subscriber number difference include: in two cells after cleaving, will be in one of cell RRU set The summation of the home subscriber number of each RRU in summation and another cell RRU set of the home subscriber number of each RRU Difference, as after classifying under the combination between cell home subscriber number difference.
For example, with cell Cell(RRU1, RRU2, RRU3, RRU4, RRU5) for, under one of combination, division Two cells afterwards are respectively: newCell-A(RRU1, RRU3, RRU5), newCell-B(RRU2, RRU4), then newCell-A Number of users be NnewCell-A=NRRU1+NRRU3+NRRU5, the number of users of newCell-B is NnewCell-B=NRRU2+NRRU4.The combination The difference of home subscriber number is N between cell after dividing under modenewCell-A-NnewCell-B
Still optionally further, if there is the identical combination of home subscriber number difference between cell after multiple divisions, Then can be further according to the interference coefficient of the identical combination of home subscriber number difference between cell after multiple division, it will Divisional mode of the maximum combination of interference coefficient as the third Target cell.
Cell after dividing under the combination is performed both by each combination in the preset number combination Between home subscriber number difference obtaining step, obtain after dividing under each combination that home subscriber number is poor between cell Value.The smallest combination of home subscriber number difference between cell after the network scheduling controller will divide, as the third mesh Mark the divisional mode of cell.
It is performed both by the divisional mode obtaining step of the third Target cell to each third Target cell, obtains this at least The division scheme of one third Target cell.
609, the network scheduling controller sends constructed cell splitting scheme to the base station.
