| Popis: | 95 With the promotion of bandwidth in network technologies. Applications are going to be various in Internet. New emerging services such as the Voice over IP (VoIP) services have low cost characteristic. SIP has high flexibility 、low complexity、high extension advantages among them. In this thesis, we would stand on the point of view from Internet telephony service provider, and focus on design and implementation in the issue of SIP Mobility. Due to maturity of wireless network technologies, the issue of terminal and application mobility have been emphasized .If there exists a high flexibility、high extension、high performance SIP mobility architecture, it would be beneficial to develop VoIP services. Focus on the SIP mobility architecture, In this thesis, we would adopt performance-oriented mechanism to achieve Terminal Mobility and Roming. Internet telephony service provider could add components flexibility in order to extend services or users, and plan grouping ways freely within service domain based on this architecture, this architecture still keeps high extension characteristic of SIP. Besides, designing a management mechanism focus on personal mobility upon service-oriented. This mechanism realizes Request forking using multicast mechanism, and reforms the drawback of wasting network layer resource in using point-to-point way, we also adds dynamic mapping way that updates the record of address in Location Server, Expecting to provide diversification services such as Context Aware services in the near future. |
