簡介：近年來，移動網絡迅速發展，隨之帶來了擁塞、網絡擴容等問題。其中，話務量的研究重點之一就是移動終端用戶的社會關系網絡。在社會關系復雜網絡研究中，對復雜網絡進行拓撲建模與拓撲優化，這兩個方面無論理論上還是在實際應用中都具有非常重要的意義。通過對復雜網絡拓撲結構的研究，一方面我們可以更好地了解和解釋現實系統所呈現出來的種種網絡特性另一方面，我們可以將研究復雜網絡拓撲結構的成果運用到具體的實際問題中，如移動通信網絡的話務量研究。論文基于復雜動態網絡的相關理論，研究移動網絡話務量問題。論文主要內容分為兩部分。第一部分是復雜網絡拓撲模型的研究，首先分析復雜網絡所表現出來的一些共同特征，并對這些共性的形成原因進行分析，得出優先連接和動態生長是復雜網絡拓撲的主要共性。然后，對INTER網絡拓撲模型進行研究和分析，提出基于消息傳遞的復雜網絡改進拓撲模型，并將其應用于社會網絡的建模。最后，根據改進模型的迭代算法，實現一個拓撲生成軟件。第二部分是移動網絡話務量研究。利用上述社會網路拓撲結構，與移動網絡的拓撲結構結合起來，根據運營商實際數據，建立移動通信網絡的話務量模型，得到每個時刻有多少移動終端用戶試圖撥出電話，有多少移動終端用戶接到了連接請求，以及每個用戶所在的基站位置等等。有了這些信息就可以用來評估移動網絡每個時刻的話務量壓力，以及產生擁塞和無效數據的可能性。論文通過基于消息傳遞的拓撲模型，建立社會網絡的拓撲結構，再利用這個拓撲結構和話務量的統計數據建立了話務量模型。最終得到某個時刻每個基站的話務量情況。
