An optimized scheme for mobile learning on IP-based network using SIP

With the fast development of wireless technology, the concept of e-learning has been constantly evolved into mobile learning(m-learning), which means to use mobile technologies to enhance the learning experience by blending mobile terminal devices and network to engage and motivate learners at any time and anywhere. However, current m-learning systems are mainly based on HTTP, which is static and limits in Web access, thus are insufficient in support of the various new mobile devices and wireless access methods. SIP(Session Initiation Protocol) is a signal protocol with excellent mobility support on both personal and service levels. The key reasons for SIP's popularity as a protocol for mobile applications are discussed in this paper. An optimized m-learning system architecture based on SIP is proposed. The mobility support of the m-learning system based on the new architecture is presented. Tests show that the new system is dynamic and mobile, with high performance in real time connection and interactivity.
