ABSTRACT:
A QoS-based call admission system and method for a mobile communication system. To establish a call for a mobile station according to the QoS of the call, upon request of setup of a call requiring a QoS guarantee, a base transceiver station determines whether a channel element is available. In the presence of an available channel element, the base transceiver station determines whether a remaining bandwidth can support a data rate required to guarantee the QoS. If the data rate is supported, the base transceiver station assigns the channel element and connects its intra switch to a base station controller. Then the base transceiver station transmits a call accept response signal to the base station controller.
