Abstract:

With the explosive proliferation of mobile communications and wireless computing devices, the scalability property is becoming an increasingly important feature of wireless communication in pervasive networking scenarios. This study provides an overview of challenges and risks that centralized architectures face under such circumstances, including what the 3GPP architecture will face in the coming years.

The study details the foundations of a new emerging convergent architecture, called Ultra Flat Architecture (UFA). In the UFA the number of logical network elements is reduced to a single access-agnostic gateway, which could be integrated into base stations or located close to base stations. The individual gateways are organized in a flat network, such that functions are carried out locally, in a distributed fashion. This new ultra-flat architecture will improve the scalability of service establishment and mobility procedures in a fixed-mobile convergence environment, integrate networks of terminals and moving networks.

The presented concept of a flat architecture for mobile and convergent networks can form the basis of new research in the future, and can lead to the preparation of a large scale European collaborative project.
