A New Control Access Solution for a Multi-provider Wireless Environment

摘要

The fundamental goal in future 4G mobile multiservice network is to provide an efficient mobile computing environment which enables a user with its portable computer equipped with multiple wireless access interfaces to seamlessly move between different providers' networks. Besides seamless roaming, a key consideration is also devoted to quatity-of-service provision. In this article, we propose a model and architectural framework for supporting end-to-end QoS in the context of interconnected multi-provider wireless systems. The proposed integrated COPS-based management and RADIUS-based control access architecture will allow providers to offer multimedia services while optimizing the use of underlying network resources. We suggest new concepts and protocols to provide solutions to the challenges and describe an ongoing research project named MMQoS to build such future networks.
