IMS网络中IPv4向IPv6演进过程中的互通问题的究-通信与信息系统专业毕业论文.docx

IPv4 IPv4 AND IPv6 INTERWORKING SOLUTION IN IMS ABSTRACT IMS(IP Multimedia Subsystem)is new network architecture for providing multimedia service in the next generation wireless networks． 3GPP has chosen SIP to be the signaling protocol in IMS． SIP is an application layer protocol，which can create，modify and terminate the multimedia session between IP users． SIP can also provide mobility management for kinds of mobility． The 3GPP R5 standards specified the use of IPv6 for the IMS． However,the speed and scale of IPv6 deployment are under our expectation．SO 3GPP R6 spedlied that IMS should also supports IPv4． Moreover,most early implementations of IMS Cores and IMS clients only support IPv4． As the transition and migration to IPv6 of both the IMS Cores and IMS clients，the interoperability between IPv4 and IPv6 in the Core and clients regions must be addressed． It iS possible that these issues will impact the access．independent nature of IMS specified by 3GPP． In this paper,we introduce a middleware which is similar to traditional Session Border Controller between Core and clients． Our proposed scheme can handle the inter-working well． Furthermore，an Interconnect．SBC like middleware is introduced to deal with the cross—IMS Cores communications． In addition，it uses 心文鼹to detect the IP capability of the IMS clients and uses the IPv6 preferred mechanism to promote the IPv6 deployment． KEY WORDS：IMS SIP SBC ANAT 独创性(或创新性)声明 独创性(或创新性)声明 本人声明所呈交的论文是本人在导师指导下进行的研究工作及取得的研究 成果。尽我所知，除了文中特别加以标注和致谢中所罗列的内容以外，论文中不 包含其他人已经发表或撰写过的研究成果，也不包含为获得北京邮电大学或其他 教育机构的学位或证书而使用过的材料。与我一同工作的同志对本研究所做的任 何贡献均已在论文中作了明确的说明并表示了谢意。 申请学位论文与资料若有不实之处，本人承担一切相关责任。 本人签名： 只期：丝塑：竺竺：!鱼 关于论文使用授权的说明 学位论文作者完全了解北京邮电大学有关保留和使用学位论文的规定，即： 研究生在校攻读学位期间论文工作的知识产权单位属北京邮电大学。学校有权保 留并向国家有关部门或机构送交论文的复印件和磁盘，允许学位论文被查阅和借 阅；学校可以公布学位论文的全部或部分内容，可以允许采用影印、缩印或其它 复制手段保存、汇编学位论文。(必威体育官网网址的学位论文在解密后遵守此规定) 必威体育官网网址论文注释：本学位论文属于必威体育官网网址在一年解密后适用本授权书。非必威体育官网网址论 文注释：本学位论文不属于必威体育官网网址范围，适用本授权书。 H 本人签名：盗茎鲨型 胁趁堡：竺兰：：垒 导师签名： 日期：2008·4·6日期： ：皇：查 IMS网络中口v4向IPv6演进过程中的互通问题的研究第一章绪 IMS网络
