a centralized resource reservation for cellular ip access networks
This paper presents a central reservation concept to enhance network performances and allow optimizing the resource utilization within the access network. The proposed approach gives an operator the capability to provide the desired QoS level with as little resources as possible, thus minimizing the operator's investment while meeting network configuration requirements. The new concept for providing IP QoS within the cellular IP network is to apply a DiffServ architecture where specific QoS classes could be adopted. Each of these classes will provide a specific QoS treatment within the access network. In the access network, the central network entity should be responsible for assigning MT (Mobile Terminating) IP traffic (addressed to the MN) to a particular class and perform a local resource reservation to this traffic. Such reservations are based on QoS profile and the network state. The central reservation for mobile node and handover management issues are analyzed in this paper.
