Abstract Provisioning of Quality of Service (QoS) is a key issue in any multi-media system.
However, in wireless systems, supporting QoS requirements of different traffic types is more
challenging due to the need to minimize two performance metrics-the probability of dropping
a handover call and the probability of blocking a new call. Since QoS requirements are not
as stringent for non-real-time traffic types, as opposed to real-time traffic, more calls can be
accommodated by releasing some bandwidth from the already admitted non-real-time traffic …
