Roadmap for Establishing Interoperability of Heterogeneous Cellular Network Technologies -3-
This ongoing paper represents a tentative approach to overcome the issue of the lack of interoperability between heterogeneous cellular access networks. It begins by establishing a holistic understanding of cellular communication via the analysis of three different cellular network technologies, and proposing an ontological framework that expresses the domain's concepts, classes, and properties in a formal and unambiguous way. After performing the study of the LTE-Advanced one and the UMTS network, it is the turn to analyze the structure of the GSM cellular technology and to produce a feature model of it. The choice of the three technologies is not arbitrary, but intentionally representing a succession of generations belonging to the same family.
