The time division multiplier networks using 2G, 3G, 4G technology terminate over 95% of voice traffic while the newer VoLTE network, currently ends less than 5% of voice traffic. Then, based on cost data and weightage between the two, an IUC can be arrived either using fully-allocated cost or long-range incremental cost. The respective costs of VoLTE and TDM can make do with a lower frequency of review, say, once in 36 months, Idea said. Yet Solution-1 (to evaluate IUC by bifurcating the calls terminating on VoLTE and rest) has the advantage of simplicity and ease of administration. According to Kapania, TDM-based networks using 2G, 3G, 4G technology are currently terminating over 95% of voice traffic; and the newer VoLTE-based 4G network, currently ends less than 5% of voice traffic.
