Quality of Service Model and Signaling for Cellular IP Access Network

Abstract

There has been a recent trend towards an all-IP network as it provides for cost-savings together with optimized network and ease of use. IP based networks are fully utilized, applications can share the same connection and QoS levels can still be guaranteed. But IP was designed for wired networks and wireless scenario was not envisioned. Owing to explosive growth of wireless users and growing demand of wireless services the internet body IETF has developed mobility management schemes to enhance IP in mobility scenarios for wireless subscribers. This trend has resulted in the development of Mobile IP to support node mobility. Mobile IP is only suitable for macro-mobility hence alternate protocols have been proposed in the literature to support seamless handoff in micro-mobile environments like cellular access networks where mobile nodes change their point of attachment frequently. Cellular IP is one of the popular solutions that support fast handoff with paging in a cellular access network. In this paper, we propose a Quality of Service model architecture based on IntServ for Cellular IP access network and describe the signaling mechanism RSVP integrated with the native protocol used to achieve the desired QoS.KeywordsAccess NetworkCellular IPQoSIntServRSVP
