摘要

在本文中,我们提出了在终端移动性共享固定业务信令基础设施的网络中预测信令流量的一般模型。该模型使用状态转换来估计调用模式和服务的使用情况。此外,还提出了将状态转换映射到物理运动的方法。我们研究了在行人交通中观察到的一些动态现象,包括队列效应、速度与密度的关系以及交通灯对行人流分布的影响。最后,给出了仿真研究的结果,并验证了该模型在预测室内和室外呼叫流量分布中的应用。我们以IS-136a标准的接口点为例说明由此观察到的信令流量。

Estimation of SS7 traffic in UMTS network
In this paper, we present a general model for the prediction of signaling traffic in a network where the terminal mobility shares the signaling infrastructure of fixed services. The model uses state transitions to estimate calling patterns and usage of services. In addition, methods of mapping state transitions to physical movements are presented. We examine a number of dynamic phenomena observed in pedestrian traffic, including platooning effects, the relationship between speed and density, and the effect of traffic lights on pedestrian flow distribution. Finally, the results of a simulation study are presented, and the model's application to the prediction of distribution of both inbuilding and outdoor offered calling traffic is demonstrated. We illustrate the resulting observed signaling traffic by taking the interface points of the IS-136a standard as an example.
