Improving quality of service in cellular IP domains

In today´s networks there is a convergence to an integrated IP-based network. lETF´s mobile IP handles global macromobility in the IP based infocommunication networks. It is, however, not adapted to micromobility environment; in this local mobility management there are several proposals both for IPv4 and IPv6. These approaches use local entities to support mobility in a well-defined area (domain), and hide the movements inside the domain from mobile IP. Future communication networks will transport not only voice calls but also other multimedia traffic. This type of data is sensible for packet delay, delay variation, packet loss, etc. To meet the requirements of users transmitting such data through the network we have to support better quality of service. In this paper we introduce an efficient solution for improving quality of service in cellular IP micromobility domains. We also show simulation results for our new method.
