项目摘要

(1) Methodology for calculating the requires spectrum for the next generation mobile radio communication systems Our proposal of the methodology and calculation results for estimating the spectrum requirements in IMT-Advanced systems was approved and accepted in the 2007 World Radiocommunication Conference. We have published the technical background and our research work in a book entitled Spectrum Requirement Planning in Wireless Communications from John Wiley and Sons (248 pages), 2008. Afterwards, we have developed a method that improves the spectrum usage, and calculated its effects based on a queuing model and simulation.(2) Calculation of the number of handovers and its application in cellular mobile communication networks In cellular mobile communication systems, the handover control is necessary when a mobile terminal moves from one cell to another for the channel allocation and location management. We have developed a theoretical model for estimating the number of handovers during one communication session using the theories of geometric probability and renewal process. The model has been applied to determine the optimal data update time for location management at the base stations in cellular mobile networks.(3) Models for evaluating the effects of time-varying traffic load on the performance of communication channels. Dynamic allocation of spectrum resource is desirable in future radio communication systems. Therefore, we have studied the time-dependent process in relevant stochastic models. We have also obtained an explicit expression for the probability density function of a busy period duration in a queue with a finite waiting room.
(1)计算下一代移动无线电通信系统所需频谱的方法我们提出的估计IMT-Advanced系统所需频谱的方法和计算结果的建议已在2007年世界无线电通信会议上获得批准和接受。我们在2008年John Wiley父子出版的一本名为《无线通信中的频谱需求规划》(248页)的书中公布了技术背景和我们的研究工作。(2)切换次数的计算及其在蜂窝移动通信网络中的应用在蜂窝移动通信系统中,当移动终端从一个小区移动到另一个小区时,切换控制是必要的,用于信道分配和位置管理。我们利用几何概率理论和更新过程理论,建立了一个估计一次通信会话切换次数的理论模型。该模型已被用于确定蜂窝移动网络中基站位置管理的最佳数据更新时间。(3)时变业务负载对通信信道性能影响的评估模型。在未来的无线通信系统中,频谱资源的动态分配是可取的。因此,我们研究了相关随机模型中的时变过程。我们还得到了有限等待室排队中忙期持续时间的概率密度函数的显式表达式。
