傳輸光衰過大導致上傳速率不達標【摘要】在日常測試單驗過程中，發現一個站點上傳異常，該站點下載等其他業務正常，在后臺的配合分析過程中，定位為該站因傳輸光衰異常導致。【關鍵字】上傳異常傳輸光衰【故障現象】：現場對臨泉鲖城站點上傳下載業務測試過程中，發現下載速率正常，滿調度，SINR等能達到好點要求。在相同位置做上傳業務RSRP良好，SINR良好，后臺跟蹤干擾檢測均在-100以下，RSSI輸出在加載和不加載的情況下均正常，但是調度較差，導致上傳速率持續較低（基本在10MBPS以下）。【原因分析】現場主要進行如下幾個方面的排查。上傳速率較低可能與服務器有關，嘗試更換服務器后做上傳業務，發現速率沒改善，和更換前服務器前一樣，上傳速率較低，嘗試在該站點各個扇區做上傳，情況相同，上傳低的情況沒改善。繼續用原服務器換個另外一個站址進行上傳業務能夠達標，排除服務器問題。異常點SINR值較高，達到30左右，可見下行無線環境較好，同時后臺跟蹤干擾檢測、小區內用戶是否接入過多、RSSI檢測，檢查結果為以上各項均正常。排除基站無線設備和頻率干擾等原因。聯系后臺檢查是否有告警，后臺反映該站點不存在告警，排除無線硬件故障。傳輸因素會影響上傳下載業務的性能，需要對該基站進行PING大包測試（大包1500KBYTE），發現丟包現象嚴重，結合以往項目經驗，定位于傳輸問題。需要傳輸側配合排查傳輸是否有光路不正常（如光衰過大導致）。傳輸人員配合光路排障后到原站址進行上傳業務，速率正常了。［解決方法】 ^出現上傳異常現象，現場人員一般從服務器異常、SINR值異常、告警、小區接入用戶數、調度情況等等入手處理。后臺人員可以通過PING測試，判斷下該站點的傳輸情況。具體執行步驟如下1.首先查詢該基站源IP和目標IP，命令為：LSTSCTPLNK詳情如下圖：十十十 咒-i舊暴-娜jHFESm-q馳性4CM 4&43CliLC:2T:?W/xaHHE203</LSrSCTFLJOCKETCODE=0執行或功3-i^cnWBeS^S.11鏈路號拒號框號nr號是大誼號控制fli式VM泰引市iSWfir地fte若第一 二市酒和號十希i一個_此批1-77 D D 7J7目勰式］7.1B4.39.1LB1D.a.0.D 3E4￡2 BEO.]ZB94 口HDTS 0 0 7IT=1三惟-1' 1fl&4.]g?lLB n.n.00 3612Z ?EC.339.142 ELCLDf也 D 。 TIT目動喉式0T.1&4.19.1L8 Oj：i.00 3明22 BW.ILLSS 0.000E0 0 0TIT目酬式0T.1E4.IB.1L8 0.0.0J：i 3G422 B.W.123.L66 0.0.ElO6L 0 0 7IT仙|口JT.1E4.32.1L6 0.0.Ojj 3fi-l￡2 fl.W.135.W O.Q.DJJ1結果中數二5：）1不尸不一II 12■STSCTTLME：sJ-中習::|_...1L'L.— rJ?_zl5Ch_'AB13 2.使用MML進行PING測試（大包1500KBYTE），具體操作如下：
