Abstract
In Next Generation Network (NGN), IP Multimedia Subsystem (IMS) plays an important role to offer IP-based multimedia services. Based on Chunghwa Telecom's NGN/IMS, we develop linear-type data transmission applications such as Bulletin Board System (BBS) or forum-based websites to deliver new articles to the mobile users. We propose the push-N method that pushes every N articles from the BBS server to the user. When the user actually connects to the BBS, the not-yet-pushed messages are pulled by the user. Our study indicates that by selecting appropriate N values, push-N can balance against the push and the pull operations, and therefore improves the user access experience without wasting too much network resources.
