Coalitional Game for the Creation of Efficient Virtual Core Network Slices in 5G Mobile Systems
TLDR
An algorithm is devised that derives the optimal number of virtual instances of 4G (MME, SGW, and PGW) or 5G (AMF, SMF, and AUSF) core network elements to meet the requirements of a specific mobile traffic.

A Complete LTE Mathematical Framework for the Network Slice Planning of the EPC
TLDR
A novel and complete solution for planning network slices of the LTE EPC, tailored for the enhanced Mobile BroadBand use case and shows that the aggregated signaling generation is a Poisson process and the data traffic exhibits self-similarity and long-range-dependence features.
