第三代個人行動通訊系統已經逐漸融入人們的日常生活中,而此一世代的個人通訊系統最大特色就是系統必須提供比以往更多元化的多媒體傳輸服務,並且根據不同的多媒體傳輸服務品質將系統所提供的服務分為四個大類:分別為對延遲靈敏的語音服務,對延遲靈敏的多媒體傳輸服務,對資料遺失敏感的數據傳輸服務,以及對資料遺失敏感的多媒體傳輸服務。在個人行動通訊系統中對於數據資料傳輸服務的服務品質保證並不容易達成,因此針對第三代行動通訊系統的架構下,提出一個較佳化的頻寬服務策略,本論文也將針對所提出的方法利用模擬的方式來評估效能,並和其他方法作為比較以證明此方法優於其他方法。
According to the requirements of data service, the third-generation systems classify the service as four types: delay-sensitive voice service, loss-sensitive data packets, delay-sensitive multimedia service, and loss-sensitive multimedia service. The quality of the multimedia service is not easy to maintain for mobility. To provide the stable quality of service, this thesis propose the bandwidth quality of service strategy for the Personal Communication System and evaluate the performance of the algorithms by simulation programs. The result of this experience can prove that the strategy of this thesis is superior to other related ones.
