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.

Facebook platform offers rich APIs and has a huge number of users and user-generated contents. This paper presents our mobile Facebook application on Android, called DEFAC, which turns Facebook contents into an ePub file step by step. Users can therefore bring contents with them for offline-reading. We expect that the interactions of e-reader\'s users and social reading services may become new important applications for both social-network services and e-book industry in the near future.
