Comparison of Policy Realization Strategies for LTE Networks

Abstract

International audienceEfficient radio resource usage and quality of service (QoS) provision are important criterions in order to choose the right QoS policy for the LTE operators. In our previous work, we have proposed to add a new database named as BSLRC (Base Station Load and Radio Conditions) to optimize the operator policy with regard to the radio efficiency [1]. Some concrete voice capacity estimations were also proposed. In this paper, we extend our earlier work by addressing some novel concerns. As a first step, we start by calculating the signaling load due to the use of BSLRC. Then, for voice services the BSLRC method is compared with the explicit congestion notification (already proposed for LTE systems). Both BSLRC and explicit congestion notification (ECN) share the same objective to optimize the choice of codec rate with regard to radio use efficiency. We also propose some capacity estimates for video services as an extension to our previously proposed voice capacity estimations over LTE systems

Measurement and Analysis of 4G/5G Mobile Signal Coverage in a Heavy Industry Environment

“…The limit values of KPIs indicating the signal quality in an RF channel are provided in Table 1 . In this work, we do not distinguish between the limit values for 4G and 5G signal quality [ 24 , 25 ]. Analyzing the correlation between KPIs (i.e., understanding how changes in one KPI may affect others) provides valuable insights into the quality and performance of a cellular network.…”
