Abstract
Two schemes of partitioning the shared channel pool between the calls of speech and data in the integral cellular communication networks were proposed. One uses the isolated partitioning procedure, the other, the virtual partitioning. The isolated partitioning forbids channel reassignment from one zone to another, whereas the virtual partitioning relies exactly on this procedure. In both schemes, the voice calls first occupy the free channels in their zone, and only if the channels of this zone are occupied, then a free channel is sought in another zone only for the handover voice call. In this case, the maximal number of handover speech calls in the zone of channels for data calls is limited. A scheme constraining the access of such calls depending on the total number of data calls in the cell is used to establish a rule for access of new data calls to the channels. Methods were developed to calculate the indices of service performance with the proposed access strategies. The results of numerical experiments were presented, and for different access strategies the indices were compared.
