“…Voice over IP (VoIP) is a popular method for the delivery of voice calls over packet-switched networks. In fact, Voice over LTE (VoLTE), a system based on VoIP, is the most promising alternative studied by 3GPP to provide voice calls over LTE networks [7,8]. Without loosing generality, in this paper, we focus on VoIP solutions based on third-party applications as a popular alternative until VoLTE is widely deployed.…”

Power consumption is a key factor in how final users rate the quality of service in mobile networks; however, its characterization is a challenging issue due to the many parameters involved and the complexity of their dependencies. Traditional battery drain testing in the field does not provide a suitable environment to reach accurate conclusions. In this paper we address this problem providing a controlled environment, more compact and accurate than those currently found in the literature, designed to measure the effects that different factors have on the global energy consumption.

When machine-type communication (MTC) devices perform the long-term evolution (LTE) attach procedure without bit rate limitations, they may produce congestion in the core network. To prevent this congestion, the LTE standard suggests using groupbased policing to regulate the maximum bit rate of all traffic generated by a group of MTC devices. However, previous studies on the access point name-aggregate maximum bit rate based on group-based policing are relatively limited. This study proposes a multistage control (MSC) mechanism to process the operations of maximum bit rate allocation based on resource-use information. For performance evaluation, this study uses a Markov chain with / / / to analyze MTC application in a 3GPP network. Traffic flow simulations in an LTE system indicate that the MSC mechanism is an effective bandwidth allocation method in an LTE system with MTC devices. Experimental results show that the MSC mechanism achieves a throughput 22.5% higher than that of the LTE standard model using the group-based policing, and it achieves a lower delay time and greater long-term fairness as well.

“…No contexto do LTE, a maioria dos simuladores encontrados na literatura tendem a contar com processos geradores de tráfego próprios (e.g. [3] e [4]). Esteé o caso do LENA [5], um módulo recentemente introduzido na plataforma ns-3, cujo uso tem crescido na comunidade faceàs funcionalidades, protocolos e interfaces LTE nele implementadas.…”
