Cellular IP and RSVP based on IPv6

For recent years, the environment of use on internet has been changed from the wired internet access to the wireless internet access increasingly, and the use of real time application data has been increased. Therefore the research and evolution of wireless network for providing of user's mobility and QoS at the same time must be essential. IETF already proposed Mobile IPv6 for providing mobility and RSVP for QoS through resource reservation. These future are expected to be used not only wired network but also wireless network. But there are not yet proposed the integration and efficient interworking of two mechanism. For the solution of problem on efficient interworking issue, for instance signaling overhead and reservation delay increasing due to often handoff, this paper first proposed to use of IETF Cellular IP based on Mobile IPv6 for wireless network model with fast mobility and a improved RSVP mechanism using the flow label field in IPv6 header.
