The objective is to design a system architecture for the next generation mobile networks. The new architecture shall support at least the new RAT(s), the Evolved E-UTRA, non-3GPP accesses and minimize access dependencies.
Proposals for the new architecture can be based on an evolution of the current architecture or based on a "clean slate" approach.
The study shall consider scenarios of migration to the new architecture.
The expected work will include:
Investigation of high-level architectural requirements.
Definition of the terminology to be used as common language for architecture discussions.
Definition of the high-level system architecture as the collection of required capabilities, and high level functions with their interactions between each other.
The complete or partial conclusions of this study will form the basis for the normative work and/or for any further study.
