Design and Production of an EPC Core Network Sizing Tool “The Case of Orange-Guinea

Abstract

With the arrival of 3G and 4G technologies, telecommunications networks have undergone a major expansion. These networks have enabled the integration of new services and adequate bandwidth, enabling operators to meet growing user demand. This rapid evolution has led operators to adapt their methods to new technologies, which increase network complexity. This complexity becomes even greater when these networks combine several different access technologies into a heterogeneous network, as in the case of 4G networks. In such cases, sizing involves new challenges such as: the considerable increase in service demands, compatibility with current networks, managing users' intercellular mobility and offering better quality of service. The solution proposed to meet these new requirements is the dimensioning of the EPC core network. The main aim of this project is to design and produce a computerized tool for sizing the EPC. The objectives of our work are in threefold : - to provide an architecture for interconnecting the EPC core network to the existing core network ; - to provide the methodology and process for sizing the core network of an EPS network; - design and implement an EPC core network dimensioning tool. In our work, traffic models are used to calculate the traffic generated by each technology to be connected to the core network. The resulting application, developed as part of our work, calculates the traffic and estimates the capacity of EPC network's core MME.
