Abstract—The evolution of the cellular networks leaves enterprises to determine how to manage today’s mobility solutions as well as future plans. Now for all of the 2G mobile backhauls, the 3G networks are the next step in the quest for speed and increase in bandwidth to provide support for more demanding multimedia applications and other next generation services. A major challenge is in the transmission backhaul of these networks. In this pursuit of migration, there is always a trade-off between merits and costs of several technical options. To address these issues, this Paper explores the possible options of the road to migration of a mobile telephony backhaul network from a traditional second generation circuit switched network, which will meet the ever growing high bandwidth demands of the subscribers, keeping in mind about the optimized benefit to cost efficiency of such a massive transformation. New challenges such as synchronization will also arise in such a migration which will be required to be dealt with in an innovative way. Solutions to such challenges will also be suggested in our proposed model.
