Abstract

The maximum traffic intensity supported by a low earth orbit (LEO) mobile satellite system (MSS) (LEO-MSS) is important in practical application for providing satisfactory service. An analytical approach is proposed for determining the maximum traffic intensity of guaranteed handover (GH) scheme and channel complete sharing (CCS) scheme in LEO-MSS under quality of service (QoS) constraints. By evaluating performance of these two schemes, the relationship between the traffic intensity and the QoS constraints is established. The expressions of maximum traffic intensity of GH scheme and CCS scheme are deduced. Compared with the traditional method, the proposed analytical approach is more computationally efficient owing to the needlessness of the repeated iteration calculation. It also avoids the complex choice of the initial value of new call traffic intensity and its increment. Lastly, the accuracy and validity of the analysis approach have been verified by computer simulations.

LEO-MSS中预设QoS要求下保证切换和信道完全共享方案的最大业务强度分析
近地轨道(LEO)移动卫星系统(MSS)所支持的最大业务强度在实际应用中对于提供令人满意的服务是重要的。提出了一种在服务质量(QoS)约束下确定LEO-MSS中保证切换(GH)方案和信道完全共享(CCS)方案的最大业务强度的分析方法。通过评估这两种方案的性能,建立了业务强度与QoS约束之间的关系。推导了GH方案和CCS方案的最大交通强度表达式。与传统方法相比,由于重复迭代计算的不必要性,所提出的分析方法计算效率更高。它还避免了新呼叫业务强度初始值及其增量的复杂选择。最后,通过计算机仿真验证了分析方法的准确性和有效性。
