Design and Implementation of a 3PCC Application System over an Embedded SIP/VoIP Gateway
eBay chief executive, Meg Whitman, at a press conference expressed to the investors that ¡§communications plays a key role in e-commerce and society. This makes Skype become the most suitable cooperator with eBay.¡¨ When integrating with Skype, eBay makes buyers and sellers communicate with each other through VoIP. This removes the biggest obstacle between buyers and sellers and achieves an ¡§unparalleled e-commerce and communications engine.¡¨
¡§eBay with Skype¡¨ is the best example of 3PCC with e-commerce. 3PCC is a model that allows an entity (which is called controller) to manage and set up a communication between two or more other parties. It has already existed in the PSTN for a long time. Although there are many applications designed for SIP, they are not 3PCC with e-commerce model. Therefore, we attempt to design an application that integrating 3PCC with e-commerce.
In this paper, we not only introduce how 3PCC is achieved but also express how REFER (a new method in SIP) can be used for replacing the traditional 3PCC mechanism in chapter 2. Chapter 3 will introduce the S/H development framework, the flows of SIP and the functions or libraries related to the Gateway. In chapter 4, we will first explain the design concept about our systems and then express how we implement the system. These include the website database structures, the Gateway programs and the packet analysis and verification. Finally, we will conclude this paper in Chapter 5. In addition, we will show the system and operation guide in appendix.
