A Question of Quality – VoIP, WebRTC or VoLTE?

چکیده
WebRTC introduces real-time media to any website with a few lines of code. This threatens the carriers’ stronghold – Voice, but could also be an opportunity to change their DNA and offer QoS web-calling alongside managed Voice. This paper proposes QoS enhanced web calling architecture for collaborative network providers, who negotiate session policy across different domains, (unlike the silo OTTs). This QoSweb service is positioned between OTT VoIP and fully-managed services (VoLTE, Enterprise, Private-Mobile). It is an affordable mid-way quality service that would mostly appeal to SMEs, who value confidentiality and predictability. To select the most suitable (and affordable) service ‘mode’, the paper proposed a modelling tool that optimizes the service delivery according to the user context. The context is computed from QoS, Urgency, Security, and Affordability (QUSA) attributes of the request, which influence the decision in different ratios. Keywords—WebRTC, QoS, Context Calling, VoLTE, TURN,

Revisiting VoIP QoE assessment methods: are they suitable for VoLTE?
Voice over LTE (VoLTE) emerges as the basis for voice services in future cellular networks. At the same time, Quality of user Experience (QoE) assessment methods have notably evolved in the last years, especially for Voice over IP (VoIP) services. The question that rises is, are these models ready to be used for VoLTE? In this paper, we contribute to answer this question by: (i) providing a hig...
متن کاملInvestigating the Extent and Impact of Time-Scaling in WebRTC Voice Traffic Under Light, Moderate and Heavily Congested Wi-Fi APs
Real-time communication (RTC) applications like VoIP ideally require networks that support the necessary quality of service (QoS) whereas the reality is that network impairments such as latency, jitter and packet loss exist. In order to cope with jitter and delay, some VoIP applications employ time-scale modification or warping in the jitter buffer that adjusts the rate of playout while control...

This paper proposes an innovative, flexible, and easily reproducible test bed that facilitates large scale multimedia (MM) quality centric experiments. It makes use of Linux container technologies and several other utilities that collectively facilitate ease of deployment, minimal resource utilisation and better reproducibility. We outline the significant advantages of this approach over physic...
متن کاملDeveloping Fuzzy Models for Estimating the Quality of VoIP
This paper presents a novel method for modeling the one-way quality prediction of VoIP, non-intrusively. Intrusive measures of voice quality suffer from common deficiency that is the need of reference signal for evaluating the quality of voice. Owing to this lack, a great deal of effort has been recently devoted for modeling voice quality prediction non-intrusively according to quality degradat...
متن کاملA New Non-intrusive Model for Measuring VoLTE Quality based on Wideband E-model
Long Term Evolution (LTE) was initially designed for a high data rates network. However, voice service is always a main service that brings a big benefit for mobile operators. Hence the deployment of Voice over LTE (VoLTE) is very essential and urgent. LTE network is a fully All-IP network, thus, the deployment of VoLTE is very complex, specially for guaranteeing of Quality of Service (QoS) to ...
