Increased performance characteristics: Clearly the intent of LTE is to improve the performance and
efficiency of the network. To realize the full potential of LTE, mobile operators must deploy core solutions
that can meet the flexible demands generated by increased mobile multimedia services and a growing
subscriber base, including increased network capacity requirements. These core solutions also must be
able to scale multidimensionally in thousands of call transactions per second, higher numbers of sessions,
and significant increase in throughput over a heterogeneous access network.

Migration from 2G or 3G to 4G: As mobile operators migrate their networks to LTE (Figure 1), they will seek
to minimize costs and maximize subscriber usage. These goals will require core solutions that can address
2G and 3G network requirements while being used for 4G network introductions. Operators will want to
avoid a complete equipment upgrade while deploying best-in-class solutions based on open standards.
Additionally, mobile users will expect a uniform service experience across both networks, with
consideration to the bandwidth differences.

Although it is likely that the evolution to 4G technologies will take many years, it is imperative for mobile operators
to identify the multimedia core elements now that will most effectively migrate them to a 4G network in the future.
Solutions designed for the specific requirements of the next-generation multimedia core network include the
capability to support 2G, 3G, and 4G functions in a single platform (Figure 2). These solutions will provide major
benefits to mobile operators who want to migrate their networks smoothly, maximize their investments, and offer
their customers an exceptional experience.
