The recent rise in data traffic volumes being carried by mobile communication networks is tremendous. Some mobile communication networks have already turned from voice dominance to data dominance in terms of carried traffic volume. In 2008 the increase was up to a factor of five, and large operators' networks are now carrying on the order of 5-10 Tbytes/day. This boom in mobile data traffic has been enabled by several factors: flat rate pricing, 3G offering digital subscriber line (DSL)-like data rates, the availability of USB mobile data modems for PCs, and Web-friendly mobile terminals. In the wake of these headlines, mobile operators are evaluating evolved network infrastructures that can simultaneously provide lower cost per bit and greater flexibility in the pricing structures of end-user services. The Third Generation Partnership Project (3GPP) has responded to these challenges with the creation of the Release 8 specification including the long term evolution (LTE) and evolved packet core (EPC) set of standards.
