4G network or Heterogeneous wireless access network will integrate existing wireless access technologies (e.g. 2G, 3G, WiMAX, WLAN, etc…) in order to provide, transparently, end-users with the “best” service through connecting their mobile devices at any time to the best available radio network. In that context, mapping the QoS classes between these different access networks becomes a big challenge. In this paper, we propose a method of mapping between the CoS of UMTS and QoS categories of WiMAX in a tight coupling architecture of Heterogeneous Wireless Access Network (HWAN)

“…Heterogeneous-technology integration has been studied by several researches. Most studies focused on networks integrating UMTS and data wireless technologies, that is, WiFi [2][3][4][5][6] and WiMAX [7][8][9]. Two inter working architectures have been proposed: loosely and tightly coupled architectures [2,10].…”

“…Figure 10 presents a regular WiFi network entry that may be executed during a first network association and an optimized reassociation procedure that may be executed during HO with an AP. In the first case, the terminal performs a regular 802.11i authentication (2, 3, 4, and 5), including exchanges with the AAA server, and the 802.11e traffic streams' establishment (6).…”

The Next Generation Wireless Networks (NGWNs) are seemed to be heterogeneous networks based on the integration of several wireless technologies. These networks are required to achieve performances equivalent to classic wireless networks by ensuring the continuity of communications and the homogeneity of network management during horizontal and vertical handovers. This task is even more important when management services, like security and quality of service (QoS), are deployed at access technology level. In this paper, we propose a framework for heterogeneous wireless technology integration based on network architecture skeleton and a handover management mechanism. This framework optimizes the layer-2 handover procedure to achieve performances required by sensitive applications while ensuring the minimization of signaling overhead required for operated networks. As an application example, we make use of this framework to propose a heterogeneous network based on WiFi and WiMAX technologies. We present an application example of the framework using the specification of a WiFi-WiMAX network. We propose several performance evaluations based on simulation tests based on this application. The latter confirm the efficiency of handover delay optimization and the minimization of management signaling costs.

“…In these proposals, the major choice concerns the depth of integration (i.e. tight or very tight integration), which implies technical modifications in the network components and protocol stacks [15][16][17][18][19][20][21]. In the tight integration scenarios, WLAN is enhanced with the required functionality that can emulate the operation of an SGSN or an RNC.…”
