Aiming at overcoming the shortages of the current slow dynamic channel allocation algorithm in TD-SCDMA system

hot cell clusters deriving algorithm was proposed.The algorithm constituted a multi-cell system model through the way that the hot cells were continuously derived to resolve the identification and expansion problem of the hot cell clusters.As the result

system capacity is increased.The simulation results show that

the hot cell clusters deriving algorithm can adapt to different service distribution models well.Compared to the hot cell algorithm

the system resource utilization is increased by 3.8 percent.
