Backhaul-Aware and Context-Aware User-Cell Association Approach

Abstract

The cell range extension (CRE) has been successfully implemented to bias the user to base station (BS) association policy in a way that achieves load balancing and increases the capacity of heterogeneous networks. The user-centric backhaul (UCB) scheme is a CRE evolution that is both backhaul-aware and user-context-aware-two constraints that are shaping the 5G network development. In this work, we formulate and solve the multi-objective optimisation problem of the UCB user-BS association. We derive analytical expressions of the ergodic throughput resulting from the UCB and, accordingly, identify the optimum association policy. The study demonstrates the gain margins that can be realised with pertinent user-cell association which is aware of the end-to-end network limitations and users requirements.

A Zero-Touch Network Service Management Approach Using AI-Enabled CDR Analysis

“…In order to capitalize on the offered degrees of freedom and traffic diversity, a holistic NPM approach is essential to curtail the limitations of the silo-based analysis. Indeed, different sections of the network can no longer be looked at independently as separate subsystems since these have transformed into a fluid architecture that requires delicate tuning [18], [19]. To this end, operators need to leverage holistic data-driven AI methods to automate the process of NPM and unravel the gain of indispensable elasticity.…”
