我们提出了一个两个时刻的蜂窝移动的网络的信道预留和不预留的性能分析。与经典的分析，切换流量建模为泊松，我们的特征切换流量作为一个一般的交通过程，并表示它使用的前两个时刻，其提供的流量。我们的经验表明，切换流量是一个平滑的过程下，负指数信道保持时间。我们还展示了如何可以确定面向客户的服务等级参数，如新的呼叫阻塞，切换呼叫阻塞，和强制终止概率下的两个时刻表示提供给每个小区的流量。我们提出了广泛的结果验证我们的分析。我们提出的两个时刻的分析与经典的单时刻分析和仿真结果的性能进行比较。我们的模拟采用五种不同的移动模型。我们表明，我们提出的模型优于现有的分析方法相比，采用所有五个移动模型的仿真结果。
We present a two-moment performance analysis of cellular mobile networks with and without channel reservation. Unlike classical analysis where handoff traffic is modeled as Poisson, we characterize handoff traffic as a general traffic process and represent it using the first two moments of its offered traffic. We empirically show that handoff traffic is a smooth process under negative exponential channel holding times. We also show how one may determine customer-oriented grade-of-service parameters such as new-call blocking, handoff call blocking, and forced termination probability under the two-moment representation of traffic offered to each cell. We present extensive results validating our analysis. We compare the performance of the proposed two-moment analysis with classical single-moment analysis and simulation results. Our simulation employs five different mobility models. We show that our proposed model outperforms the existing analytical method when compared to simulation results employing all five mobility models.
