Integrating trunking multimedia services into LTE public networks is becoming an innovation and research focus. But several aspects have to be considered for providing effective multimedia services to trunking mobile users. In particular, in this work, we design a packet scheduler for real-time downlink communication, considering both the QoS and the priority of user equipment (UE). To this aim, we exploit an innovative approach based on discrete-time linear control (DTLC) theory to satisfy the QoS requirements and add the priority of UE to determine the priority order in which the services should be scheduled. The performance of the proposed scheme has been evaluated by theory and simulations. A comparison with recently proposed scheduling strategies has also been presented. Results have clearly shown that the proposed approach is able to greatly outperform the existing ones especially in the presence of real-time video flows.

Call Admission

Call admission control (CAC) is one of the radio resource management techniques that regulates and provide resources for new or ongoing calls in the network. The existing CAC schemes wastes bandwidth due to its failure to check before degrading admitted real-time calls and it also increases the call dropping probability (CBP) and calling blocking probability (CBP) of real-time calls due to the delay incurred when bandwidth is degraded from them. This paper proposed an enhanced adaptive call admission control (EA-CAC) scheme with bandwidth reservation. The scheme employs a prior-check mechanism that ensured bandwidth to be degraded will be enough to admit the new call request. It further incorporates an adaptive degradation mechanism that degrades non-real time calls before degrading the RT calls. The performance of the EA-CAC scheme was evaluated against two existing schemes using Vienna LTE system level simulator. The EA-CAC scheme exhibits better performance compared to the two schemes in terms of throughput, CBP, and CDP of RT calls without sacrificing the performance of NRT calls.

Long-term evolution (LTE) is one of the quickest developing technologies that support a variety of applications like video conferencing, video streaming, VoIP, file transfer, and web browsing. Radio resource management (RRM) procedure is one of the key configuration parts for enhancing the system performance. The admission control is one of the resource management mechanisms. The task of admission control is to admit or reject the establishment request for the new session. In this chapter, the authors provide an overview of the resource management and analyze the media degradation path (MDP) and non-MDP-based admission control algorithms in the LTE network and compare the session establishment success. This chapter also enables for reader to know the current and future trend of research on resource management of multimedia services in LTE networks.

Wireless multimedia networks are becoming progressively popular, that provide the mobile phone users to accommodate the access of information and services at any time, any place with different configurations that user's desire. Long Term Evolution (LTE) is one of the quickest developing technology which support a variety of applications like video conferencing, video streaming, VoIP, file transfer, web browsing etc. Radio Resource Management (RRM) procedure is one of the key configuration part for enhancing the system performance. The admission control is one of the Resource management mechanisms, the task of admission control is to admit or reject the establishment request for the new session. In this chapter, we will provide an overview of the resource management and analyze the Media Degradation Path (MDP) and non MDP based admission control algorithms in the LTE network and compare the session establishment success.
