Event Abstract Back to Event An Integrated Personal Mobility Management Framework based on RFID in Heterogeneous Fixed and Mobile Networks Yun-Won Chung1* 1 Soongsil University, South Korea Personal mobility (PM) enables users to receive services through any terminal based on unique user identifier (UID) [1]. Although manual registration was needed in conventional PM [1], automatic registration using RFID technology has been proposed recently [2,3]. In [2,3], if a user with RFID tag moves into home or office, RFID reader in fixed terminal detects the RFID tag and registers the user with the terminal at registrar. Then, services can be delivered to the registered terminal, and handoff between terminals can be provided seamlessly. In [2,3], however, only fixed terminal is considered but both fixed and mobile terminals should be considered together in order to achieve true PM in future network.In this poster, we propose an integrated PM management framework based on RFID technology, as in Figure 1, where mobile networks such as cellular network and WLAN and fixed networks such as home network and office network are interworked based on all-IP core network. SIP proxy, redirect, and registrar servers are used to provide PM. Service to a user is delivered based on a chain of location information at registrar and access network: the relationship between UID and registered terminal IDs (TIDs) is managed by registrar and the location information of registered TIDs is managed by access networks. For example, the location information of mobile terminals (MTs) in cellular network is managed by home location register (HLR) by terminal mobility management. Home and office gateways also manage the location information of users moving within their domains with RFID technology. Service to UID is intelligently delivered based on the quality of service (QoS) requirement of a requested service and user preference in the service profile stored in registrar. If the delay is a more important QoS requirement, parallel forking to all registered terminals can be used. If the cost is a more important user preference in the service profile, the service is firstly delivered to a fixed network and if not found, mobile network is searched. Our future work includes performance analysis of the proposed PM management based on detailed registration and delivery procedures with QoS requirement and user preference in the service profile.
