Abstract. In the 4G mobile networks which are expected to be very complex systems interconnecting various technologies, new intelligent services will need to be aware of various contexts. In this paper, we present the context management framework that exploits the agent technology in mobile communications and services. We focus mainly on the seamless secure handover which uses context information regarding location privacy, security, network environment, and QoS priority. We designed QoS Broker that can perform the autonomous decision making for context-aware handover without the direct intervention of users. To minimize the signaling overhead, we present an efficient context transfer mechanism among the Brokers. We also designed the context model for the seamless vertical handovers so that the Brokers could ensure the right context is available in the right place at right time. We developed the testbed and analyzed the performance of QoS-aware secure roaming with context transfer. Analytical results show that our context-aware vertical handover provides better performance and security with lower latency.

This paper presents a predictive mobility management framework with the secure context management in mobile networks. We devised the authentication method for seamless handovers that exploit the knowledge of the mobility prediction. Previous Access Router (AR) forwards the preestablished context information to the new AR in the predicted target wireless cell where MN might move in the near future. Therefore the context for autonomous services is available in the right place at right time.

This paper proposes novel concepts and architectures for location-aware seamless authentication and roaming in the new interworking system between third-generation (3G) mobile networks and wireless local area networks (WLANs) where local mobility movements (micromobility) are handled together with global movements (macro-mobility). We introduce location as a key context in secure roaming mechanism for context-aware interworking. The fast secure roaming with locationaware authentication is implemented at an entity called LBS Broker that utilizes the concepts of direction of user and pre-warming zone. We present the interworking techniques with LBS Broker for seamless secure WLAN/3G integration enabling to meet the requirements of the future location-aware service scenarios. Performance evaluation is also presented to demonstrate the effectiveness of the proposed scheme for fast location-aware secure roaming.
