PROJECT TITLE :

Dynamic SON-Enabled Location Management in LTE Networks - 2018

ABSTRACT:

Wireless networks face various challenges that demand continuous and rapid improvement. Long-Term Evolution (LTE) is a most popular wireless technology as a result of of its satisfactory performance. Owing to an exponential increase in demand and new potential applications, the core network of LTE, which is known as the Evolved Packet Core (EPC), is suffering from a surge in signaling caused by a variety of control functions. The signaling overhead decreases the users' Quality of Experience (QoE). This study attempts to boost the intelligence of location management techniques. As an extension of our previous study [1], a Self-Organizing Network (SON) that permits dynamic reconfiguration of cell-to-TAL/MME is introduced. Each centralized and distributed pooling schemes are tested in terms of signaling overhead and user power consumption. A decomposition model that reduces the initial formulated problem to 2 sub-issues is proposed, every of that is solved optimally. In addition, a sensible cell-to-TAL choice theme is proposed to prioritize potential cells that might be visited by a user equipment (UE). Our technique is shown to outperform many state-of-the-art ways presented within the literature. Finally, a heuristic algorithm is presented to get a less complicated resolution than the optimal one.
