Migration towards NGN: Common Applied Strategies

Telecommunication service providers (SP) around the world are still in the process of migrating away from legacy networks towards next generation networks (NGN). The strategies for this have been and are different depending on the size of the market, historical background or financial resources of the SP just to name a few. This paper addresses these strategies mainly from a non-technical point of view aiming at seeking commonalities amongst different SPs. The migration processes of two smaller European countries have been looked at more closely to complement the dominant research done towards similar processes in larger countries to see if there are equally compatible strategies for different SPs irrespective of their background and properties. The work concludes that above all the size of the operator is a key factor in the transition to NGN.
