EVOLUTION OF IP SUBSCRIBER MANAGEMENT IN MOBILE NETWORKS — KEEPING CHURN AT BAY 1 © Ovum 2009. Unauthorised reproduction prohibited. Evolution of IP subscriber management in mobile networks — keeping churn at bay Executive summary In a nutshell Exciting new mobile services, devices, and applications are on the horizon, but only if mobile operators can effectively manage scarce network resources and grow profits. LTE isn’t a silver bullet for the industry, so information technologies originally developed to optimize applications over IP wide area networks can and are being applied to solve mobile bandwidth bottlenecks to satisfy ever more demanding mobile customers. Ovum view IP traffic growth in both wireline and mobile networks is projected to skyrocket, but revenues aren’t expected to keep pace. This rapid bandwidth growth is a greater engineering challenge for mobile operators than wireline operators because over-the-air bandwidth is a fixed and scarce commodity. Thus, mobile bandwidth exhaust is a serious concern for the mobile industry, particularly with the recent, rampant success of mobile broadband IP-based services. Securing more wireless spectrum isn’t a viable option in most countries, although forward-looking government regulators should be considering this option. LTE radio access technology will provide some short-term bandwidth relief, but since bandwidth is “addictive”, greater mobile bandwidth availability is likely to fuel more end-user demand for it. Raising prices could slow bandwidth demand but this is difficult to do in a competitive market, as share loss, alternative solutions, or allegations of illegal collusion may result. Ovum believes other solutions are needed and preferable to best optimize mobile bandwidth in the face of rapid growth. Evolving mobile infrastructure across all layers IP introduces new systems architecture opportunities Mobile infrastructure will require a holistic evolution plan that spans all OSI transport and application layers to effectively address the challenges mobile operators will face. Cobbling together best-of-breed point solutions of disparate technologies just won’t do. One often-overlooked aspect of mobile infrastructure

Mobile broadband growth — the coming tsunami Mobile isn’t just for voice anymore — industry estimates are that a typical mobile broadband-connected laptop uses the same bandwidth as over 400 cell phones. Smartphones currently use less bandwidth than a laptop, but are rapidly growing
