“…Similarly, NBR-NBD schemes proposed in [42][43][44][45][46][47][48][49] are designed to address unfairness problem and ensure QoS for admitted calls. These schemes neither reserve nor degrade already assigned resources but achieve fairness and QoS for admitted calls except for scheme in [44] that have poor QoS because it only considers the channel quality of calls once (when they are admitted) and scheme in [48] that is unfair due to the prioritization policy used.…”

The growing number of mobile users with diverse applications such as VoIP, video, internet surfing etc. has made LTE networks to adopt a CAC strategy in order to ensure the quality of service (QoS) requirements of these applications. Over the years, several CAC schemes have been proposed to either accept or reject service requests. This paper presents a survey of these schemes under four different classes. The classes are: Bandwidth Reservation (BR), Bandwidth Degradation (BD), BR and BD and Non-BR and Non-BD (NBR-NBD). In each of the classification, the operation procedure, strengths and weaknesses of each scheme has been discussed. Furthermore, a comparative analysis of these schemes is also presented. The analysis provides insight into the challenges in the design of CAC by highlighting open research issues for future directions.

“…Their types are New-call blocking, the failure of the initial call connection establishment and Handoff call dropping, the blocking of in-service calls when they move from one cell to another [9,10]. From user's point of view, it is better to block a new call rather than dropping a call in the middle [12].…”

In order to allocate resources for real-time traffic flows to meet their Quality of Service (QoS) requirements, Priority based fair Resource Allocation and Admission Control (PRAAC) technique forMulti-class downlink Traffic in LTE-A networks is proposed. In this technique, priority of the nodes is estimated based on the Tolerance of Latency, bandwidth and data arrival rate. This technique includes a two level resource allocation scheme, wherein the first level a radio admission control (RAC) scheme is introduced. In the second level, RAC combines the complete sharing (CS) and virtual partitioning (VP) resource allocation models. Simulation results show that the proposed technique achieves better throughput for Video and the Exponential traffic performs well when compared to CBR traffics in all aspects.Copy Right, IJAR, 2016,.

New social applications, high-definition multimedia, and other services have made mobile terminals the main connectivity tool for several users, i.e., users want to have the same experience as on a fixed computer. The upcoming standard from 3rd Generation Partnership Program (3GPP) named long-term evolution advanced (LTE-A) targets the support of such high requirements services. Relaying is an appealing technology that was introduced in LTE-A to provide seamless connection and high achievable data rates to the users located in the cell-edge or in coverage holes. Relay nodes (RN) are low power evolved NodeB (eNB) which, when deployed in the macro cell, improve the signal quality between the user equipment (UE) and eNB by dividing the radio link into two hops: the so-called backhaul link between the RN and the eNB, which in this context, is referred to as the Donor eNB (DeNB), and the so-called access link between the RN and the UE [1].Resource allocation among multiple users sharing the whole spectrum bandwidth is one of the key design tasks in LTE systems. The aim here is to optimally assign resources to those users which need them, keeping in view not only their resource requirements, but also their instantaneous channel quality, instantaneous service quality, and the allocation history. Although, the presence of RN (multi-hop transmission) has proved to enhance the LTE system, it introduces some additional design challenges in the traditional resource allocation task [1]. In order to maintain minimal QoS, proper utilization of the bandwidth in the form of appropriate distribution is to be done. The resource allocation impacts on the applications utilizing the LTE network.
