This paper reports on work aimed at designing a dynamic system-level simulator for wireless telecommunication networks. Presented here are considerations devoted to the development of a software tool, a preliminary condition for the analysis of various technological aspects directed towards the enhancement of WCDMA (Wideband Code Division Multiple Access) technology by implementing SON (Self Organized Networks) functionality. The future broadening of such strategies to include multi-technology networks will be possible with the created methodology and software library. Compared to typical attempts in this research domain, which involve pure software representations of wireless system operations, the methodology offered in this paper creates a tool that has direct practical value, which is primarily based on operations on input data measured in an actual wireless telecommunications system. Thus, both detailed cases concerning wireless communication in a chosen region of the world and general ideas of a conceptual nature can be considered with the support of an IRSON (Integrated Research on SON) system-level simulator. Details on the assumptions and designs of the simulator and its verification (primarily through feasibility studies) are sketched together with exemplary qualitative and quantitative results concerning its operation. These results prove that the imitation of conditions in a wireless communications network is possible with a designed part of an IRSON simulator for any vendor and network operating in any geographic location. At this level, processes inside the system of a WCDMA network can be monitored in the direction of optimal handover management, but other mechanisms are consecutively implemented to flexibly join various technologies (inter-RAT), layers (multi-frequency) and deployments (macro-, micro-, pico- or femto-cell) within a coherent and exact tool. Apart from the planning, optimization and management of an actual network, another practical application of IRSON concerns the design of new features for future mobile telecommunication technologies. |
