“…For legacy-based applications, QoS procedures are triggered by the CSC at the MS (CSC_MS), which is responsible for controlling end-to-end QoS signaling procedures using the NSIS framework. After obtaining the application QoS parameters through the WEIRD Agent (WA) module, the CSC_MS translates the received QoS parameters to a dedicated WiMAX QoS Specification (QSPEC), defined for the NSIS model [15], and initiates the end-to-end QoS signaling. For IMS-based applications, the QoS procedures are initiated on the network side by the SIP Proxy, which intercepts the SIP signaling originated at the WiMAX MS SIP User Agent (SIP UA).…”

Although IEEE 802.16 has emerged as one of the major candidates for next generation networks, it is also clear that in the near future the combination of several technologies will be required. In this sense, the support of mobility in heterogeneous environments, addressing broadband wireless, is one of the main requirements in next generation networks. This paper evaluates an architecture based on the recently standardized IEEE 802.21 framework, integrating both mobility and Quality of Service (QoS) mechanisms, through an advanced mobility scenario using a real WiMAX testbed. This architecture supports seamless mobility in broadband wireless access (BWA) networks, integrates different technologies, such as WiMAX and Wi-Fi, and thus, it is suitable for next generation network environments.The results, obtained through real experimentation of the implemented architecture, show that it is able to provide QoS under dynamic scenarios, with fast integrated QoS and mobility signaling.

“…Beyond the WiMAX segment, the initiator QSPEC must be mapped to local QSPECs and be placed on the top of the QSPEC stack such that internal nodes process only the local QoS parameters, omitting the attributes that otherwise could not be understood anyways. A more detailed treatment of this subject can be found in [12].…”

The IEEE 802.16 standard provides a specification for a fixed and mobile broadband wireless access system, offering high data rate transmission of multimedia services with different Quality-of-Service (QoS) requirements through the air interface. The WiMAX Forum, going beyond the air interface, defined an end-to-end WiMAX network architecture, based on an all-IP platform in order to complete the standards required for a commercial rollout of WiMAX as broadband wireless access solution. As the WiMAX network architecture is only a functional specification, this paper focuses on an innovative solution for an end-to-end WiMAX network architecture offering in compliance with the WiMAX Forum specification. To our best knowledge, this is the first WiMAX architecture built by a research consortium globally and was performed within the framework of the European IST project WEIRD (WiMAX Extension to Isolated Research Data networks). One of the principal features of our architecture is support for end-to-end QoS achieved by the integration of resource control in the WiMAX wireless link and the resource management in the wired domains in the network core. In this paper we present the architectural design of these QoS features in the overall WiMAX all-IP framework and their functional as well as performance evaluation. The presented results can safely be considered as unique and timely for any WiMAX system integrator.
