“…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.

“…In this paper, the definition below is of the QoS perspective that is used to test and evaluate the performance of the experimental network infrastructure, in "high quality" services transmission. ITU-T (Recommendation E.800 [ITU-TE.800]) and ETSI [ETSI-ETR003] basically define Quality of Service (QoS) as "the collective effect of service performance which determines the degree of satisfaction of a user of the service" [1]. Mainly, QoS is the ability to differentiate between traffic types in order for the network to treat certain traffic flows differently from others and keep to acceptable level the service categorization and the overall network performance [1].…”

The creation and wide use of new high quality demanding services (VoIP, High Quality Video Streaming) and the delivery of them over already saturated core and access network infrastructures have created the necessity for E2E QoS provisioning. Network Providers use at their infrastructures several kinds of mechanisms and techniques for providing QoS. Most known and widely used technologies are MPLS and DiffServ. The IEEE 802.16-2004 standard (WiMAX) refers to a promising wireless broadband technology with enhanced QoS support algorithms. This document presents an experimental network infrastructure providing E2E QoS, using a combination of MPLS and DiffServ technologies in the core network and WiMAX technology as the wireless access medium for high priority services (VoIP, High Quality Video Streaming) transmission. The main scope is to map the traffic prioritization and classification attributes of the core network to the access network in a way which does not affect the E2E QoS provisioning. The performance evaluation will be done by introducing different kinds of traffic scenarios in a saturated and overloaded network environment. The evaluation will prove that this combination made feasible the E2E QoS provisioning while keeping the initial constrains as well as the services delivered over a wireless network.
