Next generation core, next generation access and next generation service control will form the next generation networks. Although it is impossible to tell, which business models will emerge and prevail, it is most important not to unnecessarily restrict innovation, evolution and growth.
A next generation environment might look like this:
There will exist many next generation core networks with nearly unlimited bandwidth in the backbone. These networks will be based on IP/MPLS and not be restricted to regional boundaries.
Next generation core networks can be global with access points worldwide or can cover a specific region. Core networks will be inter-connected and will also be connected to various access networks.
Next generation access networks are from a technical perspective local or regional, although alliances between different players might form. Access providers might also provide backbone services but need not do so. Next generation access networks are connected to one or many core networks.
Next generation service control might be developed functionally separated or fully integrated with the infrastructure (next generation access and next generation core). Next generation service control needs to be accessed through the core network by the customer premises equipment. Although the access and the core are seen as technologically transparent for services certain restrictions from a business point of view might apply.
In a pure next generation environment the customer has the choice to connect to different access networks. He or she will also be able to choose the services independently from the access if he or she wants to. There will be bundles of integrated solutions, which might suit the customer's need for a single point of contact. If the market forces work, unbundled access will exist together with bundled products and all will find their respective markets. Access providers on the other hand will have the opportunity to choose between core network providers or provide their own core network.
Service providers will be able to offer their services to some access and core providers but not necessarily to all. Since nobody can foretell this evolution the best way forward is to provide a favourable environment and watch the evolution closely. If the market forces lead to common standards for interoperability and interconnection and to an environment free of bottlenecks, no intervention will be necessary.
