In this paper, we integrate the channel assignment and

power assignment into a distributed channel access

algorithm. A cost-function is introduced to provide some

optional channels according to their cost for transmitted

power level searching. The simulation results show that this

algorithm largely increases capacity compared with the

fixed channel allocation (FCA). The proposed algorithm

can adapt to the call saturated state of network and does not

cause high intracell handover access. It has a short average

call setup time even at high traffic loads. We suggest that

the intracell handover rate should be a factor in evaluation

of an algorithm’s performance, because high handover

access will intensively increase the load of switch and cause

much higher call dropping and blocking probabilities than

those we expect.
