What LTE policy control features can operators execute to differentiate themselves from OTT players?

Mobile Network Operators (MNOs) are currently facing challenging times. With flat revenues and intense competition from `Over The Top' (OTT) providers, they are searching for new opportunities that will enable revenue growth. The impending migration towards LTE presents a number of challenges as well as opportunities, especially in the area of Policy Control. The Evolved Packet Core (EPC) architecture provides an enhanced feature set in the Policy and Charging Rules Function (PCRF) which, coupled with the advanced capabilities of the LTE radio access technology (e.g. improved speed, latency etc.), opens up a wealth of potential possibilities within this domain that operators may need to consider. This paper aims to explore those areas in more detail, discussing what LTE Policy Control features operators can implement in order to generate revenue growth to differentiate themselves from OTT providers.
