Abstract
Wireless personal communication networks are evolving to provide integrated multimedia services to mobile users. An important issue in their design is the accommodation of various services each having predefined Quality-of-Service (QoS) requirements. Efficient resource utilization can be achieved using a medium access scheme that allows various traffic components to be statistically multiplexed and a call admission control to prevent overload. Some multimedia services have asymmetric resource needs. For example, web browsing generally requires more downlink bandwidth than uplink bandwidth. We present a medium access scheme and a call admission control algorithm for guaranteed QoS provisioning in asymmetric integrated multimedia personal communication networks. An overall performance analysis model is developed. Performance characteristics are calculated and presented for an example system.
