Next generation mobile radio networks of IMT Advanced systems family will offer ubiquitous broadband high area coverage, at up to 1 GBit/s in cities and 100 MBit/s in rural areas and QoS support in terms of throughput and low delay. Candidate technologies like 3GPP-LTE, WiMAX, as well as the WINNER system design are based on OFDMA transmission for flexible radio resource allocation, scalable and adaptable...
In order to offer a better QoS during L2 handover of a mobile station, we propose in this paper to compare the performance of the two L2 HO techniques: Soft and Hard handover for different types of traffic with same architecture IEEE 802.16e in an urban area (City).
The convergence of radio access technologies with all-IP core network has gained significant attention recently. Through the all-IP based policy and charging control (PCC) architecture standardized in 3GPP R8, the charging rules are consistent with application-level and IP-level policy control. It is essential to investigate the signaling overhead incurred by PCC and the OCS management during the...
This paper presents the architecture, design, implementation and samples of tests performed on a testbed for IEEE 802.16/WiMax access technology while used in a multi-domain environment IP networks. The final target was to implement a system capable to offer connectivity services, with different levels of end to end QoS guarantees, adaptable to different applications. Flexible solutions are proposed...
High-speed switching, QoS provisioning, security, and mobility are main challenges faced with existing networks and to be confronted by NGN researchers and developers. To address these challenges, SUPANET has been proposed in recent years. But all works on SUPANET have been mainly devoted to high-speed switching and QoS issues, so far, there is no research on the mobility management of SUPANET. To...
A key aspect of the 3GPP system architecture evolution is the specification of an evolved packet core that supports multiple access networks. The EPC enables operators to deploy and operate one common packet core network for 3GPP radio accesses (E-UTRAN, UTRAN, and GERAN), as well as other wireless and wireline access networks (e.g., eHRPD, WLAN, WIMAX, and DSL/Cable), providing the operator with...
Wireless mobility seems to be transforming the communication industry, shifting the momentum from Internet access to broadband wireless access. This technology-shifting has been expected to provide a better communication services in return. The ability to transfer communication at extremely high speeds and the ability to stay connected during a fast movement speed should always be applicable for the...
A collection of slides from the author's conference presentation is given. It is concluded that: QoS for subscribers is a potential additional business case for Access Network operators; technology is mature and proven; - QoS support can be added to Ethernet-based access networks at low initial investment which will lead to gradual upgrade upon customer acceptance.
