Mobile data services become increasingly important in the age of wireless broadband data access. We propose a service platform that can provide context-aware and localized/personalized data services. We involve the data broadcasting and publish/subscribe techniques into our system. A prototyping system for a mobile guiding application is implemented. This guiding system is different from most modern...
3GPP 43.318 specifies the generic access network (GAN) for interworking between wireless local area network (WLAN) and Universal Mobile Telecommunications System (UMTS) core network.

This paper proposes an analytical model and conducts...
