Inter-regional voice bandwidth calculation on IMS network

Abstract

The inter-regional telecommunication network design in Indonesia is strongly influenced by the bandwidth of Voice over Internet Protocol (VoIP), where 40% of the national bandwidth is used to pass voice communication. Indonesia region is divided into seven regional areas; each of these is supported by two IMS Cores, which serves as the active core and the stand-by core. Regionals are interconnected with each other through an IP backbone network. It serves to get through a number of bandwidth when there is communication between the regionals. The bandwidth requirement can be obtained through the calculation of traffic in regional, inter-regional traffic, and along with demographic data as well as the number of customers who have registered on the IMS network. Since voice traffic is passed in IP networks, the voice bandwidth is calculated in bps (bits per second) units. Standard voice codecs used for the conversion are G.711 and G.729. The national bandwidth load for voice traffic on the IMS backbone network can be obtained using mathematical calculations. The results of the calculation are presented in bandwidth matrices of the seven regions traffic for each standard (G.711 and G.729).
