小区驻留时间变化对一种先进寻呼算法性能的影响
Effect of cell residence time variance on the performance of an advanced paging algorithm
摘要：
已经建议使用高级顺序寻呼算法作为在未来移动蜂窝网络中减少信令成本的手段。在一个建议的算法（Koukendis和Theologou，2003年），该系统可以使用的附加信息的最后一个互动小区结合移动性模型来预测短期的位置概率在一个来电到达的时间。短期定位概率减少了移动用户位置的不确定性，从而大大提高了搜索。在本文中，推导出一个分析模型，允许细胞停留时间的一般分布。通过考虑Gamma分布，我们研究了细胞停留时间的方差的影响，并得出有用的结果上的算法的性能。
英文摘要：
The use of advanced sequential paging algorithms has been suggested as a means to reduce the signaling cost in future mobile cellular networks. In a proposed algorithm (Koukoutsidis and Theologou, 2003), the system can use the additional information of the last interaction cell combined with a mobility model to predict the short-term location probabilities at the time of an incoming call arrival. The short-term location probabilities reduce the uncertainty in mobile user position and thus greatly improve the search. In this paper, an analytical model is derived that allows for a general distribution of cell residence times. By considering a Gamma distribution, we study the effect of the variance of cell residence times and derive useful results on the performance of the algorithm.
