IEEE 802.16e下行訊息產生與解析之軟體實現
Software implementation of IEEE 802.16e downlink message generation and analysis
摘要
IEEE 802.16俗稱WiMAX是定位於都會型的無線網路標準，也是未來通訊產業的發展方向，被譽為是4G(generation)的原型(prototype)，預計最快2009年就會進入商業化的階段。在IEEE 802.16中規範了物理層與MAC層，而MAC層中依功能又可區分成兩個子層：收斂子層(Convergence Sublayer ,CS)，MAC通用子層(MAC Common Part Sublayer, MAC CPS)。802.16規格依據移動性的支援與否區分為802.16d與802.16e(支援移動)，而本論文所要實現的是802.16e之MAC通用子層的管理訊息產生與解析模組，其目的在於建立符合IEEE 802.16e-2005標準的通訊測試軟體。在下行訊息產生模組方面，可以依據使用者的輸入參數，產生相應的下行管理訊息(Management Message)及虛擬的下行資料叢訊(Burst)。在下行訊息解析模組方面，則能對來自物理層的MPDU進行正確性的驗證與解析的工作，若有下行管理訊息以外的MPDU資料則會直接送往應用層做處理。

IEEE 802.16e can be thought as WiMAX in general and which is a standard of Metropolitain area network, look upon WiMAX as the prototype of 4G(Generation), the service of WiMAX will soon start at 2009. IEEE 802.16 defined PHY layer and MAC layer, according to functionality MAC layer can be divided into two layers: Convergence Sublayer(CS) and MAC Common part sublayer (MAC CPS). IEEE 802.16 can be divided into 802.16d and 802.16e if support of mobility function, in the thesis we perform MAC management message generation and analysis module of MAC CPS, the major purpose of present implementation is to build communication testing software depend on IEEE 802.16-2005 Std. In aspect of MAC management message generation module, it could generate corresponding Downlink Management message and pseudo Downlink Burst according to user’s input. In aspect of MAC management message analysis module, it could verify and read MPDU that come from PHY layer, if MPDU can’t be analysis, it could be send to application layer.
