Fang Xu-min · Dianzi xuebao · 2000
This paper proposes a new dynamic channel assignment strategy in cellular mobile communication systems, which is called compact Pattern based channel borrowing assignment strategy (CPCB). The new strategy combines the advantages of compact pattern dynamic channel assignment with fixed channel assignment with channel borrowing. CPCB is simulated in the conventional 49cell network. Compared with the average blocking probabilities of fixed channel assignment (FCA), borrowing with directional channel locking (BDCL), compact pattern based dynamic channel assignment (CPDCA) and compact Pattern with maximized channel borrowing (CPMCB) in various uniform and nonuniform traffic load distribution, the simulation results indicate that with the increase of traffic load,the system average blocking Probability of CPCB is lower than those of FCA,BDCL,CPDCA etc.. Besides,the growth the of the blocking Probability is the lower than that of the above strategies significantly.
