Multimedia traffic management principles for guaranteed wireless network performance

The third generation of wireless network systems will support numerous multimedia services with stringent quality of service. How to unify the diverse technologies required in the wireless systems and effectively control the radio resource to offer uniform broadband services is a great challenge. A protocol reference model for the future global wireless network is proposed in the paper. The detail implementations of different radio access techniques are hidden by the wireless adaptation layer. The proposed model makes it possible for old and new systems to coexist, and it will lead to an evolutionary path from the second generation wireless network to the future generation systems. Packet transfer mode has been chosen as the target transfer mode. Principles of multimedia traffic control and resource management are suggested to guarantee both quality-of-service (QOS) and network performance.<
