NGN Architectures

A difficult path, but worth it: The migration to all-IP reduces overall costs, eliminates certain costs entirely, and increases efficiency. The challenge is to completely transform production and achieve a shift in the provider’s culture and organization.

For today’s network operators, the efficient “production” of all products and services is essential for a profitable and viable business case. It is generally assumed that all services will be transported, routed, and accessed via a single network platform in the future. The launch of the LTE (Long Term Evolution) mobile standard was the final signal that all of these basic networks will have to be migrated to the uniform all-IP standard. A Next Generation Network (NGN) is a unified network platform that transports and provides data and information, largely independent of services, and is able to integrate virtually all physical network access possibilities. This transforms the typically vertical production set-up of a traditional telecommunications provider into an efficient, future-proof network and production model with a horizontal layout. This change will affect nearly all processes and structures within the company.

Achieving this target is a remote prospect at present due to the established structures in place at nearly all telecommunications companies and the considerable costs of migrating all platforms. Technology platforms that have not yet been amortized and unassessed migration risks are causing hesitation among many CTOs. The result: substantial efficiency gains are not being fully exploited.

 

Migrating to an NGN architecture is first and foremost a business decision. Extensive analyses are necessary before the operational migration can begin:

  • Analysis of existing technology platforms
  • Technology strategy development and maturity level evaluations
  • Product and features road map
  • Traffic modeling
  • NGN architecture and concept
  • Migration steps and planning
  • Planning, design, and implementation of networks and technology platforms
  • Sourcing strategy, tender management, and contract negotiation
  • Implementation and program management
