RFID has been adopted so far in business fields due to such problems as expensive tag price, privacy issue, no tiny reader, etc. But currently RIFD is being adopted in cell phones so that customer-purposes RFID applications can be provided in the B2C manner. How to establish the service infra is a challenging issue and only the case of KDDI is known to the public. It operates based on the service broker model. But this paper describes the E2E-based communication model. It figures out prospective network entities, network configurations, how to resolve the code resolution from an RFID code to a URI (uniform resource identifier), how to retrieve information contents such as music, video, game, etc. With this result, an alternative network reference model can be suggested to the market and Koreas mobile network operators are adopting this proposed architecture

This paper proposes mobile RFID service architecture using RFID tags of B2B. To use RFID tags of B2B in mobile RFID service network, two approaches may be available. One is that network entities in mobile RFID service network access to network entities in B2B network and uses contents of B2B for mobile RFID service. The other is that only UII in RFID tag is used in mobile RFID service which does not require access to network entities in B2B. For these purposes this paper proposes mobile RFID service gateway. Also the requirements and the functions of the service gateway are defined.

The wireless LAN is a potential candidate technology for providing wireless access services. Also, wireless LAN can meet demands for expended wireless access coverage while maintaining continuous connectivity from one wireless LAN to another by supporting Mobile IP. Along with these, many standard organizations are considering Mobile 1Pv6 for their mobility management protocol in the next generation network. IETF is developing Hierarchical Mobile IPv6 and Fast Handoff for Mobile 1Pv6 to provide fast handoff mechanisms with Mobile 1Pv6. In this paper the Mobile 1Pv6 and its handoff issues an introduced. The three factors that affect Mobile IP handoff delay, movement detection, address configuration location update, are analyzed thoroughly. At last, consideration; for designing fast handoff mechanisms reducing Mobile IP handoff delay are suggested.

IP-based mobility management is considered as core technology in the next generation network environment since the core network is moving toward all IP network and IP-based wireless LANs are blooming. Mobile IPv6 is developed to support mobility in global network, and hierarchical mobile IPv6 is being considered as a local mobility management protocol to reduce signaling overhead for mobility management in the global network. However, they seem to be designed without paging technology, which allows reducing signaling overhead within the access network for mobility management. In this paper, we propose the P-HMIPv6 which enables IP paging service in the hierarchical mobile IPv6 to reduce signaling overhead for local mobility management in the MAP domain of the hierarchical mobile IPv6.

We propose a secure framework for mobile-phone based RFID service using personal privacy policy based access control for personalized ultrahigh frequency (UHF) tags employing the Electronic Product Code (EPC). The framework, called mobile RPS, has dynamic capabilities that extend upon extent trust-building service mechanisms for RFID systems. This new technology aims to provide absolute confidentiality with only basic tags.
