Abstract
A call admission method and apparatus are disclosed which maximizes the wireless channel utilization subject to a predetermined bound on the call dropping and packet loss probabilities for variable-bit-rate traffic in a packet switched network. The call admission scheme is stochastic and dynamic, hence it is able to adapt to a wide range of traffic fluctuations and mobility patterns. The call admission scheme disclosed satisfies a set of constraints on call dropping and packet loss probabilities while maintaining high bandwidth utilization.
