  • 專業解析

    呼叫接納控制(Call Admission Control,CAC)是通信網絡中确保服務質量(QoS)的核心機制,主要用于評估和決策是否允許新呼叫請求接入網絡。其核心功能包含以下三方面:

    1. 資源動态評估

      系統實時監測網絡帶寬、信道占用率等關鍵參數,當新呼叫請求到達時,基于預設算法(如等效帶寬計算模型預測資源消耗量。國際電信聯盟(ITU)在标準建議書G.1011中明确了多業務場景下的接納控制框架。

    2. 服務質量保障

      通過預設門限值拒絕超額請求,優先保障已接入呼叫的傳輸穩定性。例如蜂窩網絡采用基于幹擾測量的接納算法,避免信道過載導緻的通話中斷。這一機制在3GPP TS 23.107規範中被定義為UMTS QoS架構的核心組件。

    3. 多場景應用擴展

      現代軟件定義網絡(SDN)通過集中控制器實現跨層資源協調,5G網絡切片技術則結合機器學習預測業務負載趨勢。IEEE通信協會在《Network Slicing Whitepaper》中指出,動态CAC算法可提升切片資源利用率達30%以上。

    網絡擴展資料

    “Call Admission Control”(CAC,呼叫準入控制)是通信網絡中的一種資源管理機制,用于決定是否允許新的呼叫或連接請求進入系統,以确保網絡服務質量(QoS)和資源合理分配。以下為詳細解釋:


    1. 術語拆解


    2. 整體含義

    CAC的核心作用是評估當前網絡資源是否足夠支持新呼叫,若資源不足則拒絕接入,避免過載導緻服務質量下降。常見應用場景包括:


    3. 技術實現方式


    4. 示例

    在蜂窩網絡中,當用戶發起視頻通話請求時,CAC會檢查基站可用帶寬:


    CAC通過智能決策平衡網絡負載,是保障通信穩定性和服務質量的關鍵技術。如需更深入的技術細節,可參考網絡工程或QoS相關文獻()。
