结果表明，该方案可以显著降低切换呼叫阻塞概率，并使新呼叫阻塞概率得到改善。
It is shown that the scheme can reduce the handoff call blocking probability observably, and new call blocking probability is improved at the same time.
然后在这个模型的基础上，分别得到了系统的平均下行传输速率和数据包呼叫请求阻塞概率。
Based on this model, the average downlink transmission rate and the call blocking probability of packets can be obtained.
该方案为切换呼叫提供了保留信道，降低了切换呼叫的阻塞概率。
The scheme provided reserved channel for handover call to reduce blocking probability of handoff call.
