Abstract: For the transition from a single band network to a dualband network, the cellular operator may encounter the problem of how to control the traffic of dualband mobile stations so as to minimize the blocking probabilities of all type of mobiles. Definitely, a "no control" strategy is clearly not desirable from a performance point of view. An easy and effective control strategy has to be created to cater for this problem. This dissertation has discussed the problem of managing the traffic in the GSM / DCS dualband system by incorporating the so-called Threshold-Type (TT) call control strategy and a proposed strategy called Dynamic Traffic Handover (DTH). Those two algorithms are simulated in a traffic model that is specially designed according to the usual dualband network implementation methods nowadays. It is found that the proposed traffic control strategy is easier to operate and it can provide similar traffic capacity as that of TT TH. There is just a minor drawback of DTH which is a higher handover rate. However, the increment is very insignificant and is masked by the normal handover rate of the real GSM network.
