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.
