WiMAX通訊系統架構與監察機制研究

隨著網路之普及，透過網路的犯罪行為也日益增加。為了打擊網路犯罪，合法監察是一重要的手段，可以透過監察作業取得犯罪者的通訊，以得知其下一步的行動，因此針對網路監聽的研究便成為一大重要的議題。本研究提出一適用於WiMAX監察的連線訊號流程，藉以監察WiMAX網路上之網路通訊行為。本論文針對移動式WiMAX網路之通訊服務提出不同監察的策略，依作業方式不同可區分為固定式與機動式，並分析及比較各方式之優缺點。本論文以網路電話來作為犯罪偵防時的案例，其主要原因在於此策略可運作於現行的網路。最後，針對WiMAX通訊系統架構提出相對應的監察機制，提出系統設計與架構，以驗證系統運作的可行性，並分析比較各種不同監察作業的優缺點。

The crime behaviors are increasing through network recently with the high den-sity of network. For the sake of bitting crime on Internet, interception of this would be an important way to get the communication data of the crimers in order to know what they will do next activity such that the research of interception network become a critical issue. This research proposed a architecture of interception according to the flow of connection in WiMAX network in which we can intercept the data. This research proposed difference strategies of interception on WiMAX network. There are two approaches that are fixed style and mobility style. We analyze and compare these approaches’ prob and cons. We use Voice over IP to be the case that shows this would be able to operate. According to the properities of WiMAX communication network that we propsed the proper machaism of interception. We designed the interception system to justify the capability of the system.
