一般來說,SIP (Session Initiation Protocol)協定通常被用來在UDP環境下建立即時的通訊;另一方面,mobile IP則被用來傳輸非即時性的TCP通訊。為了有效地整合SIP與mobile IP (MIP),許多文獻在探討SIP/MIP的混合架構。目前的討論多集中在緊緻耦合(tightly coupled)架構,亦即MIP和SIP兩者的位置資料庫彼此會交換位置更動的訊息。但是在許多場合,提供語音服務和數據服務的ISP業者往往不是同一家,SIP和MIP的位置資料庫也就不會互相交換訊息,這樣的架構稱為鬆耦合(loosely coupled)架構。本論文係針對鬆耦合架構提出跨層式(cross-layer)位置管理機制,依不同使用者的環境與習慣,採用三種不同的模式: HoA、Sequential、Parallel,以期減少註冊及通話成本。高通話率的使用者適用於Sequential模式,減少連線時所需花費的時間,Parallel、HoA模式不會造成INVITE的Miss,適合高漫遊率的使用者,HoA則可以有效減少發送INVITE的成本。
Generally speaking, SIP is used for the real-time communication, which is under the environment of UDP; On the other hand, mobile IP is used for TCP, which provides non real-time services. In order to integrate SIP and mobile IP (MIP) efficiently, many papers proposed the hybrid structure of SIP/MIP.
The discussion so far only focus on the tightly coupled structure, in other words, it means that the database of MIP and SIP would exchange the message and even share one database with each other. However, in many occasions, ISP is not the only one provides data and voice services, therefore, both the database of SIP and MIP would not exchange the message with each other, while this is so called loosely coupled structure. This research not only aims to tightly-coupled structure, but also provides the management scheme in order to reduce the cost of updating databases of SIP/MIP.
