Network-Centric Architecture for Context- Aware Information Delivery Services in 3G Mobile Networks
نویسندگان
چکیده
This paper proposes a context-aware information delivery system (CAIDS) using a UMTS Release 5 architecture and a wireless LAN. We present the concept and the system architecture of CAIDS, discuss the disposition of functional modules using the network-centric approach and clarify the CAIDS can provide the users with context-aware information delivery services including context-aware personal communication services. In addition, we discuss the preliminary evaluations of CAIDS performance in terms of the response time. The result indicates that the performance of application servers is a dominant factor of the response time in CAIDS.
