“…This experimental setup aims not only to evaluate the SIP‐based VoIP performance over IMS core using wireless connectivity but also to examine voice connectivity delay and service throughput rate of the networks. As illustrated in Figure , the sum throughput rate of the proposed algorithm is significantly higher compared to UGS, rtPS, and other related services, especially when the number of emergency voice call sessions are higher. It is evident that the proposed framework achieves well‐nigh optimal performance and surmount the other existing services, namely, UGS, rtPS, and other works by at least 40%, when the number of emergency call sessions is 700.…”

Third Generation Partnership Project (3GPP) standardizes the Long‐Term Evolution (LTE) to improve the quality of service in modern communication systems using 3GPP LTE‐advanced (LTE‐A) networks. As this technology is converging with modern devices, efficient resource allocation schemes are essential for minimization of the communication delay for the sensitive real‐time devices. To achieve the demands of latest technologies, this paper proposes two novel mechanisms, enhanced real‐time polling system with continuous time–batch Markovian arrival process and proactive resource allocation framework. The objective of the former mechanism is to improvise the service connectivity between the multimedia devices in LTE‐A networks and the latter is to exploit the transmission bits in each user's buffer in addition to the state information of wireless channel. The proposed mechanisms consider the constraints enforced by 3GPP standard in terms of radio resource blocks allocation for LTE‐A networks. In addition, the proposed mechanisms use LTE‐A networks to investigate the Voice over LTE traffic in order to analyze various quality‐of‐service measures, namely, sum throughput, session setup delay, packet delivery ratio, resource utilization ratio, and throughput improvement via real‐time multimedia client‐server systems. The probing results show that the proposed algorithm is superior in comparison to other typical services of IEEE 802.16d/e–based systems as well as LTE‐A system with 7 orthogonal frequency‐division multiplexing symbols over a duration slot 0.5 ms. While the slotted duration is set to 5 ms, the proposed framework effectively utilizes the resource allocation cycle to support the uplink scheduling to outperform at least 38% better throughput performance in comparison with existing mechanisms.

Summary Guaranteeing a certain delay threshold for delay‐sensitive applications in long term evolution (LTE) cellular communication system is a very challenging mission. By implementing an optimal scheduling strategy, this mission will be achieved. In this article, a novel scheduler is introduced in order to meet a predefined level of service quality by guaranteeing a specific delay threshold for delay‐sensitive applications in LTE cellular systems. The proposed scheduler assigns the available resource blocks (RBs) to active user equipments (UEs) tacking into consideration several attributes. The expiration date of each packet, the channel quality, the average data rate previously achieved by each UE, and the number of dropped packets for each UE compared with the average number of packets totally dropped are all considered in the proposed scheduler working mechanism. Consequently, the proposed scheduling strategy reduces the number of packets dropped for multimedia applications, and at the same time maximizes the overall throughput of the network. Simulation results are provided to study and evaluate the performance of the proposed scheduling strategy. A comparative study is presented between the proposed strategy and the most recent scheduling techniques. The obtained results prove that the proposed scheduling strategy has considerably acceptable and appreciated results compared with the results of the state‐of‐the‐art scheduling techniques.
