“…Effectively using the finite network resources can cut the cost of every bit of transferred data or second of calls. As the popularity of LTE smart terminals is rising continuously and service providers are porting their applications from former legacy platforms like GSM/UMTS to the new one, LTE will highlight the need for end-to-end QoS requirements to serve various service demands [1], [2].…”

-In order to effectively deliver traffic from different applications, providing end-to-end Quality of Service (QoS) is critical in Long Term Evolution (LTE) networks. Mobility requires special handling of QoS enforcement rules and methods. The LTE QoS Signaling (LQSIG) protocol presented in this paper will allow ensuring resource reservation before using a data path. Operation of the proposed protocol in different mobility scenarios is also explained. The key features of the protocol include LTE QoS model mapping to QSPEC (QoS Specification) objects used in reservation and interworking with mobility protocols in the LTE protocol stack, especially with Radio Resource Control (RRC). The basics of an analytical model are proposed in order to determine the blocking probability at the bottlenecks of LTE network. A performance analysis of LQSIG describes its properties compared to legacy LTE networks.

“…The 3GPP Release 8 has standardized QoS concept of the EPS. In the EPS QoS concept [10], [11], the bearer is the basic level of granularity for QoS control. An EPS bearer carries data between P-GW and UE.…”

“…These two principles provide access network operators and service operators with a set of tools to enable service and subscriber differentiation. While the service differentiation includes Public Internet, corporate VPN, peer-to-peer (P2P) file sharing, video streaming, IMS and non-IMS voice, mobile TV etc., the subscriber differentiation includes pre-paid/ post-paid, business/ standard, roamers etc [10]. In the network initiated QoS control, only network can make the decision to establish or modify a bearer.…”

Abstract-3GPP LTE/SAE is a next generation radio access system that supports future end-user requirements. The fundamental aim of long-term evolution (LTE) is to improve the service provisioning and reduce user and operators cost, which will be fulfilled by improving data rates, coverage, system capacity and reducing latency. The paper presents the technical overview of Long Term Evolution (LTE)/ System Architecture Evolution (SAE), the QoS provisioning aspects of Evolved Packet System (EPS), the key research challenges and the ongoing work to provide solutions. The discussion also provides an insight into 3GPP LTE-Advanced, which is the future of LTE on the roadway to 4G. The paper provides the valuable and concise information to the researchers in the area of 3GPP LTE and 4G.

Abstract-Long Term Evolution (LTE), the standard specified by 3GPP on the way towards the fourth generation mobile networks, is intended to deliver high speed data and multimedia services to next generation mobile users. The Radio Resource Management (RRM) plays a very crucial role in managing limited radio resources to enhance system's data rate and to ensure quality of service (QoS) provisioning in both uplink and downlink. LTE downlink scheduling is a RRM entity that is responsible for the allocation of shared radio resources among mobile user equipment (UEs). One of the challenges that need to be addressed in downlink scheduling algorithms is to provide higher spectral efficiency with fairness ensured to all its users. This paper proposes a novel downlink scheduling algorithm which balances its performance between efficiency (in terms of throughput) and fairness to users. The algorithm makes use of Assignment Model for resource allocation to all the selected users during each Transmission Time Interval (TTI). The proposed algorithm is simulated and the simulation results are compared with three techniques proposed in literature. The simulator results show that the new algorithm balances well between throughput and fairness.
