【摘要】:隨著智能終端的不斷增多和LTE技術(shù)的不斷完善,基于IMS網(wǎng)絡(luò)的VoLTE語(yǔ)音解決方案,實(shí)現(xiàn)了數(shù)據(jù)與語(yǔ)音業(yè)務(wù)在同一網(wǎng)絡(luò)下的統(tǒng)一,為用戶(hù)提供了高質(zhì)量語(yǔ)音服務(wù)和用戶(hù)體驗(yàn),已成為國(guó)內(nèi)三大運(yùn)營(yíng)商推進(jìn)的方向。但由于VoLTE業(yè)務(wù)在國(guó)內(nèi)仍處于測(cè)試、商用初期階段,其VoLTE業(yè)務(wù)性能的評(píng)價(jià)也處于理論分析過(guò)程,因此,對(duì)聯(lián)通VoLTE業(yè)務(wù)性能的評(píng)價(jià)與技術(shù)改進(jìn)策略研究,有助于其VoLTE業(yè)務(wù)的拓展和技術(shù)改進(jìn)。論文在系統(tǒng)梳理VoLTE業(yè)務(wù)性能評(píng)價(jià)研究成果的基礎(chǔ)上,分析了聯(lián)通VoLTE業(yè)務(wù)架構(gòu)、業(yè)務(wù)性能指標(biāo)及其評(píng)價(jià)指標(biāo)體系建立的途徑,利用魚(yú)刺圖和雷達(dá)圖指出了VoLTE業(yè)務(wù)性能指標(biāo)改進(jìn)的方向;其次,依據(jù)VoLTE業(yè)務(wù)性能測(cè)試的內(nèi)容和雷達(dá)圖,提出了VoLTE業(yè)務(wù)技術(shù)改進(jìn)的策略。按照VoLTE業(yè)務(wù)場(chǎng)景要求,論文通過(guò)對(duì)SPS、TTI Bundling、ROHC頭壓縮等的測(cè)試工作,分析了信令開(kāi)銷(xiāo)的優(yōu)化(魯棒性報(bào)頭壓縮(ROHC)、半靜態(tài)調(diào)度(SPS)的應(yīng)用場(chǎng)景)和VoLTE覆蓋增強(qiáng)技術(shù)(包括TTI Bundling的應(yīng)用場(chǎng)景)、VoLTE語(yǔ)音解決方案等問(wèn)題。論文第一章主要介紹VoLTE業(yè)務(wù)發(fā)展的情況、論文研究的意義、相關(guān)研究文獻(xiàn)綜述,及論文研究的思路與方法;第二章主要介紹VoLTE業(yè)務(wù)架構(gòu)、核心網(wǎng)IMS、VoLTE業(yè)務(wù)流程分析等;第三章主要分析VoLTE業(yè)務(wù)性能指標(biāo)的構(gòu)成及其影響因素、VoLTE業(yè)務(wù)性能評(píng)價(jià)方法及評(píng)價(jià)途徑;第四章為VoLTE性能測(cè)試途徑與技術(shù)改進(jìn)策略,主要分析了聯(lián)通VoLTE性能測(cè)試內(nèi)容和步驟,提出了VoLTE性能改進(jìn)策略。
[Abstract]:With the increasing number of intelligent terminals and the continuous improvement of LTE technology, the VoLTE voice solution based on IMS network realizes the unification of data and voice service under the same network, and provides high quality voice service and user experience for users. Has become the three major domestic operators to promote the direction. However, the VoLTE service is still in the testing stage in China, and the evaluation of its VoLTE service performance is also in the process of theoretical analysis. Therefore, the performance evaluation and technical improvement strategy of Unicom VoLTE service are studied. Contribute to the expansion of its VoLTE business and technical improvements. On the basis of systematically combing the research results of VoLTE service performance evaluation, the paper analyzes the VoLTE service architecture, business performance index and the way to establish the evaluation index system of Unicom. The improvement direction of VoLTE service performance index is pointed out by using fish-burr map and radar map. Secondly, according to the content of VoLTE service performance test and radar diagram, the improvement strategy of VoLTE service technology is put forward. According to the requirement of VoLTE service scenario, the paper analyzes the optimization of signaling overhead (robust header compression (ROHC),) by testing SPS,TTI Bundling,ROHC header compression and so on. Semi-static scheduling (SPS) application scenarios and VoLTE coverage enhancement technology (including TTI Bundling application scenario), VoLTE voice solution) and other issues. The first chapter mainly introduces the development of VoLTE business, the significance of the research, the literature review, and the ideas and methods of the paper, the second chapter mainly introduces the VoLTE business architecture, core network IMS,VoLTE business process analysis and so on. The third chapter mainly analyzes the composition of VoLTE service performance index and its influencing factors, VoLTE service performance evaluation method and evaluation approach; The fourth chapter is the VoLTE performance testing approach and technical improvement strategy, mainly analyzes the Unicom VoLTE performance testing content and steps, and proposes a VoLTE performance improvement strategy.
