Abstract The Voice over the Internet Protocol (VoIP) for international calls to either family or friends or business is the most common form of communication in the last period. Since the Internet is easily accessible to maximum people, VoIP is a modest way to lower expensive fares. However, because of the delay and low speed, VoIP systems over mobile networks can achieve higher data rates than the regular 3G network. In order to deal with such high data speeds, greater capacity and less latency, long term evolution (LTE) were created. VoIP is required to allow LTE network voice calls. This paper looks at VoIP service quality (QoS) through the LTE network by providing two case studies on the topology of the LTE network. Relative VoIP QoS analysis is carried out by parameter measurement. Keywords LTE · VoIP · QoS
1 Introduction Over recent years, we have seen the incredible rise in the use of smartphone and mobile data. This increase in use is causing a huge increase in mobile network Internet traffic. LTE is standard for mobile and data terminals to handle high speed wireless communication. It is also the first fully IP-based 3GPP wireless standard. It offers up to 50 Mbps on the uplink (UL), and downlink (DL) at 100 Mbps [1]. Engineers are presented with a critical problem to improve, automate and audit voice traffic over S. A.

data networks. Based on the study of virtual traffic or actual terms, several schemes were suggested. In [2], they addressed how to handle the most popular VoIP codecs on a Wi-MAX network utilizing different service groups. The different types of network groups were contrasted to QoS. The performance of unified LAN/WAN wireless VoIP scenarios is tested using an optimization framework in [3]. Various QoS parameters are calculated and the proper VoIP codec was suggested on the basis of this evaluation. The parameters that affect VoIP’s quality through heterogeneous networks, such as Wi-Fi, Wi-MAX, and beyond that, can be identified by using the OPNET simulation tool and are evaluated in [4] for QoS performance simulation through UMTS and Wi-Fi (IEEE 802.11x) alone [5]. VoIP service quality (QoS) is analyzed on the LTE network in [6]. The performance of the test is simulated by measuring parameters and different scenarios. The accompanying paper examines comparative QoS for VoIP over the LTE network utilizing bandwidth, jitter, end-to-end latency and packet failure measurements. The paper is organized in this way. The LTE design is listed in Sect
