ITU-T's Study Group 19 has developed and approved a technical report that will facilitate interoperable and harmonized wireless network architectures. This is a key aspect of the overall ITU-T focus on next generation networks (NGN).
The convergence of fixed and wireless networks has become a key topic for forward-looking standardization, especially in NGN. This, together with the convergence of telecommunication and information technologies, and the drive for migration to interoperable and harmonized network architectures, means that there is a requirement to provide global roaming and seamless mobility for the users of the different access technologies used by different operators.
To this end, ITU-T's Study Group 19 is leading the definition of requirements, related architecture framework, and network to network interfaces (NNIs) for mobility management for the next generation mobile networks defined in ITU-T's systems beyond IMT-2000. The technical report by Study Group 19 identifies the requirements that will enable the development of protocols which are essential for the development of next generation mobile networks. It is recommended reading for anyone working in this area as it provides an excellent summary of the requirements and options for meeting them.
