Call placement algorithm evaluation for integrated networks that overflow speech or data
Susan Lincke‐Salecker, Cynthia S. Hood · 2002
As network providers implement multiple network types, including 2G and 3G networks and potentially 1G, WLL, and/or satellite, it becomes feasible to overflow traffic between these diverse networks. This results in an increase in capacity, because the Erlang model of traffic analysis shows that a large network provides efficiency of scale. This paper analyzes the gains in efficiency when dual mode phones may overflow to diverse networks, via handover, thus increasing the number of channels available to these phones and minimizing the blocking rate. The analysis compares different call handling models, via simulation and M-dimensional Markov chain models, which overflow speech and data calls between subnets.
