Impact of busy lines and mobility on call blocking in a PCS network

摘要: Several analytical models have been proposed to study the blocking probability for personal communications service networks or mobile phone networks. These cannot accurately predict because they do not capture two important features. First, busy-line effect. Even if a cell has free channels, incoming and outgoing calls must be dropped when destination portable is already in conversation. Second, mobility of individual portables. In these models, addressed by net hand-off traffic cell, which results with smaller variance compared true situation. We propose new analytic model addresses both effect mobility. Furthermore, our can used derive population distribution cell. The validated against simulation experiments. indicate that previously approximate special case where number portables 40 times larger than channels.
