BCG2 - D1 BCG2 Architecture

BCG2 project investigates the potential energy savings that can be achieved from a new system architecture based on the separation between signaling and data networks at the radio interface of mobile access networks. In this first Deliverable of the project we present the general system architecture. However, since the goal of the project is not that of designing and specifying into details the new system, rather that of opening a new research area and proving guidelines for the green mobile communication systems of the future, the role of this architecture work is not that of taking definitive design decisions. Instead, with this Deliverable we aim at providing a common framework to the possible research directions and open options in the system design we will consider during the project. For this reason this documents has several goals: i) identifying the main system components that can be mapped into physical devices; ii) identifying the main system functionalities and services that can be provided through the collaboration of the system components; iii) Identifying the design options for the system components and functionalities. BCG2 system architecture has been structured its basic components and functionalities. The system components are physical devices or network portions that are devoted to specific roles. The system functionalities are logical functions, composed of algorithms and communication protocols, which can be implemented and localized in the physical components in different possible ways.
