In this vein, our paper proposes a novel and complete solution for planning network slices of the LTE EPC, tailored for the enhanced Mobile BroadBand use case. The solution defines a framework which consists of: i) an abstraction of the LTE workload generation process, ii) a compound traffic model, iii) performance models of the whole LTE network, and iv) an algorithm to jointly perform the resource dimensioning and network embedding. Our results show that the aggregated signaling generation is a Poisson process and the data traffic exhibits self-similarity and long-range-dependence features. The proposed performance models for the LTE network rely on these results. We formulate the joint optimization problem of resources dimensioning and embedding of a virtualized EPC and propose a heuristic to solve it. By using simulation tools, we validate the proper operation of our solution.}, organization = {This work is partially supported by the European Unions Horizon 2020 research and innovation programme under the 5G!Pagoda project with grant agreement No. 723172, the Spanish Ministry of Education, Culture and Sport (FPU Grant 13/04833), the Spanish Ministry of Economy and Competitiveness, the European Regional Development Fund (TEC2016-76795-C6-4-R), the Academy of Finland’s Flagship programme 6Genesis under grant agreement no. 318927, and the Academy of Finland Project CSN under grant agreement no. 311654.}, publisher = {Institute of Electrical and Electronics Engineers (IEEE)}, keywords = {LTE}, keywords = {EPC}, keywords = {Network Slicing}, keywords = {NFV}, keywords = {Softwarized Networks}, keywords = {Mobile Networks}, keywords = {Traffic characterization}, keywords = {Resources dimensioning}, keywords = {Network embedding}, title = {A Complete LTE Mathematical Framework for the Network Slice Planning of the EPC}, doi = {10.1109/TMC.2018.2890235}, author = {Prados Garzón, Jonathan and Laghrissi, Abdelquoddouss and Bagaa, Miloud and Taleb, Tarik and López Soler, Juan Manuel}, }
