因應更加多元的網路服務到來,服務品質的需求也逐漸提升。為達到無所不在的網路環境架構,各式各樣的無線網路協定與標準陸續被提出並使用,由多種類型的無線網路所建構而成的異質無線網路也相對的帶來許多極待解決的問題。
首先,最重要的問題為網路的服務品質。服務品質自網際網路剛發展之際即被提出,然而早期的網路傳輸是以盡力服務為主,雖有服務品質的概念,卻也受限於網路的傳輸頻寬、傳輸距離、網路負載……等多種因素影響。近年來,隨著軟硬體技術的進步,許多過去難以達成的目標紛紛被實現。各家制定網路標準的組織也提出新世代的網路協定與架構,雖然各式標準定義了服務品質,然而在實現的方式與設計的架構上卻是不盡相同。
本論文研究以LTE(Long Term Evolution)與WIMAX(Worldwide Interoperability for Microwave Access)無線網路為主,提出具服務品質保證之智慧型異質無線網路架構,用以整合異質無線網路的服務品質。


QoS(quality of service) requirements is increasing by variety services of network services provided. Each kind of wireless network protocols and standards was proposed to build the omnipresent wireless network environments, but also bring a large number of problems.
The first important issue is the QoS, since the period of Internet beginning. In early periods, network transmission was restricted by limits of bandwidth, transmission distance and network loading even the QoS has definition. In recent years, various wireless networks related organizes proposed new generation protocols and standards with techniques of software and hardware progressing. Even that new protocols and standards has the same QoS concept but the designs and architectures are different.
In this paper, we focus in LTE(Long Term Evolution) and WIMAX(Worldwide Interoperability for Microwave Access) wireless networks to propose “Intelligent framework for heterogeneous wireless networks with QoS guarantees” to integrate different QoS performances in heterogeneous wireless networks. We will show the proposed methods will be worked well in the NS3 simulator.
