The functionality of a radio base station (RBS) is divided into two main parts: user-plane functions and control-plane functions. The user-plane functions are associated with transport, baseband, radio and the antenna. The control-plane functions pertain to the transmission of user data and operation and maintenance (O&M) data. Ericsson's RBS is based on(More)
In order to evaluate and increase modularity this paper combines a method for visualizing and measuring software architectures and two algorithms for decoupling. The combination is tested on a software system at Ericsson. Our analysis show that the system has one large cluster of components (18% of the system, a Core), all interacting with each other.
