In this thesis, we proposed a bang-bang type call admission control(CAC) algorithm using total received power as thresholds when there exist multiple types of services. Analysis and simulation of the CAC is provided under the perfect power control in the sense that the received power at the base station is the same. First we derive the power requirement that makes the capacity maximum. Then, it is shown that the cell load and SIR can be expressed as total received power at base station. That is, cell load and SIR are reflected in total received power. In the proposed CAC, we inserted the transmitter(or terminal) removal procedure that disconnects the calls if the system is under operation below required SIR. Multiple threshold scheme is investigated and compared with a single threshold scheme. The proposed scheme can also provide the flexibility of multiple threshold scheme over the single threshold. As a result, the proposed multiple threshold scheme can be considered as a priority scheme. Various allocation of threshold values for voice and data results in corresponding priority over the other. Extensive simulation results are provided to evaluate the performance.
