中文摘要
在本論文中,我們提出了一個在第三代無線多媒體傳輸環境下執行的新的連線允諾控制法和動態資源配置法。我們所提出的連線允諾控制法是利用measurement based的方式來即時取得網路的流量情形,根據這個即時流量的資料,動態地調整允諾控制法中的參數,來決定是否接受一通新的連線。除此之外,當一通新的連線進來,我們採用一個低複雜度的動態頻寬配置來讓整個系統的頻寬使用率達到最高。利用我們所提出的連線允諾控制法和動態資源配置法不僅可以讓系統的服務品質保持在一個固定的水準之上,同時還可以減少連線的中斷率,並增加連線的完成率。
此外,在第三代無線通訊系統上,其所傳輸的資料型態非常的多,而且其重要性也不相同,如何為每一個不同的連線設定一個適當的優先權來維持其應有的服務品質是一件重要的事。因此,在本論文中,我們也描述了一個設定優先權的方法。根據模擬結果顯示,經由我們所描述的優先權設定方法,我們的連線允諾控制法和動態頻寬配置法可以讓擁有高優先權的連線有相對較高的服務品質,並且保證在正常情況下緊急的連線可以隨時連線並順利完成。
Abstract
In this thesis, we proposed a call admission control algorithm (CAC) and an adaptive allocation of resource algorithm (AAR) for 3G wireless multimedia data transmission. The proposed CAC algorithm uses a measurement-based method by measuring real-time network load to modulate the parameters of the CAC algorithm and to decide whether to accept a call or not. When a call is admitted, the proposed AAR algorithm uses a low complexity algorithm to adaptively allocate bandwidth for the call to improve resource utilization. Taking advantages of the proposed CAC and AAR algorithms, the desired quality of service (QoS) can be maintained, the call forced termination probabilities can be reduced, and the call completion probabilities can be increased.
In addition, there are a variety of types of data in 3G wireless communication networks. To set a proper priority for different data to maintain a desired QoS is important. Therefore, we also proposed a scheme to set priority for each call. On the basis of this scheme, simulation results show that the proposed CAC algorithm and the AAR algorithm can forward the call with higher priority to get relative higher QoS, and guarantee that an emergency call can go through and complete at any time in a normal situation.
