基于5020MGC的ISUP与SIP的互通研究的中期报告摘要：本文介绍了基于5020MGC的ISUP与SIP的互通研究的中期进展。首先，简要介绍了ISUP和SIP协议的基本原理和特点。然后，对现有的ISUP与SIP互通方案进行了分析，并针对其存在的问题提出了优化设计策略。在此基础上，提出了一种基于5020MGC的ISUP与SIP互通方案。该方案实现了ISUP和SIP之间的互通，并具有灵活、高效、安全等优点。最后，通过实验对该方案进行了验证，结果表明该方案实现了预期的功能，具有良好的可行性和实用性。关键词：5020MGC；ISUP；SIP；互通；优化设计；可行性验证Abstract:Thispaperintroducesthemid-termprogressoftheresearchontheinteroperabilityofISUPandSIPbasedon5020MGC.Firstly,thebasicprinciplesandcharacteristicsofISUPandSIPprotocolsarebrieflyintroduced.Then,theexistingISUPandSIPinteroperabilityschemesareanalyzed,andoptimizationdesignstrategiesareproposedfortheproblemsexistingintheschemes.Onthisbasis,aISUPandSIPinteroperabilityschemebasedon5020MGCisproposed.TheschemerealizestheinteroperabilitybetweenISUPandSIP,andhastheadvantagesofflexibility,highefficiencyandsecurity.Finally,theschemeisverifiedbyexperiments,andtheresultsshowthattheschemerealizestheexpectedfunctions,andhasgoodfeasibilityandpracticality.Keywords:5020MGC;ISUP;SIP;Interoperability;Optimizationdesign;Feasibilityverification
