为了有效地规划未来的个人通信服务(PCS)，我们需要解决一维(1-D)、二维(2-D)和三维(3-D)微或微微蜂窝环境中的各种移动性/流量问题。然而，到目前为止，移动性/交通问题主要是在一维和二维小区结构中进行研究的。在本文中，我们将以往的移动模型从一维或二维空间扩展到三维室内建筑环境中，通过考虑每一层的适当边界条件，并解析地建模多层建筑中的移动性来估计切换次数。然后，我们提出了一个具有移动性的阻塞概率模型，作为三维室内环境下的流量模型。利用该模型，我们可以在给定的阻塞概率约束下，得到每个小区所需的信道数目。这些结果可用于规划未来PCS的网络。
To efficiently plan future personal communications services (PCSs), we need to solve various mobility/traffic problems in one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) micro or picocell environments. However, mobility/traffic problems have thus far primarily been studied in 1-D and 2-D cell structures. In this paper, we extend the previous mobility modeling from 1-D or 2-D space to 3-D indoor building environments by considering the proper boundary conditions on each floor and analytically modeling mobility in multi-story buildings to estimate the number of handoffs. We then propose a blocking probability model with mobility as a traffic model in 3-D indoor environments. Utilizing this model, we can obtain the required number of channels per cell under the given blocking probability constraint. These results can be utilized in planning the networks of future PCSs.
