Performance analysis of dynamic channel allocation strategy on hierarchical cellular networks 分层式动态信道分配移动通信系统的性能分析
This paper deals with the capacity of hybrid channel allocation ( hca ) over cdma network 摘要讨论了cdma网络中混合信道分配策略的容量问题。
A series of techniques which aim to increase the system capacity and some arithmetic on channel allocation are introduced in chapter 2 too 然后详细介绍了蜂窝网无线通信系统的容量扩展技术、信道分配技术。
Analyzing fixed channel and dynamic channel we obtained the substantive capacities and brought them into an inhibitable equation for channel allocation proportion 通过分析动态信道和固定信道得到各自的独立容量,将其联立作为信道分配比例的制约方程。
A new optimized channel allocation scheme is proposed according to the model of idsm , and a control model of synchronization communication ( dscm ) is proposed based on the optimized channel allocation scheme , including server dscm and client dscm 依据idsm模型,提出了一个新的优化信道分配方案,并在此基础上,提出了同步通信控制模型dscm ,包括服务器dscm模型和客户dscm模型。
In this thesis , the handover and channel assignment schemes in leo - mss are introduced and discussed deeply . on the basis of the integrated consideration on handover , channel allocation and resource reservation , the appropriate handover and allocation techniques are proposed so as to reduce the call blocking probability and handover failure probability . thus , the proposed schemes can improve the channel utilization efficiency and the system performance 本文对低地球轨道( lowearthorbit , leo )卫星通信系统中的切换与信道分配策略作了较为深入的研究,将切换与信道分配、资源预留等因素综合考虑,采用合适的切换算法来降低呼叫阻塞率和切换失败率,提高资源利用率,从而改善系统性能。
In this thesis , the complicated temporal relationship and dynamic synchronization properties existed in multimedia in distributed multimedia system , and the problem of higher priority demands of key medium in application , and etc . are studied thoroughly ; the course of multimedia communication , the transmission characteristics and the synchronization requirements of multimedia objects , and the algorithms of channel allocation and synchronization transmission schedule in synchronization communication scheme , and etc . are studied deeply ; at the same time , the problems of multimedia synchronization control mechanism in the practical packet - switching networks and so on are studied too 本文深入研究了分布式多媒体系统中,多媒体具有的复杂的时态关系和动态同步特性,以及关键媒体在应用中享有同步优先权等问题;深入研究了多媒体通信过程和多媒体对象的传输特性、同步需求,以及同步通信方案中信道分配以及同步传输调度算法等问题;同时,深入研究了实际分组交换网络中多媒体同步控制机制等问题。
