Thesis abstract:

The mobile communication systems evolved considerably in the last few years. This fact encouraged the deployment of several systems or cellular networks in multi technological environment. The Quality of Service (QoS) offered to the mobile users improves from one system to another one. The systems of third generation (3G), like UMTS, offer a better quality of service compared to that offered by those of second generation (2G), like the GSM. For example, the systems of 3.5G (HSDPA) improve the throughput of the network of 3G in the downlink direction according to the requirements of the new services. Moreover, the networks of fourth generation (4G), like WiMax (IEEE802.16e), as for them, make it possible to widen the cover of the base station while offering a very important throughput in which supports the next generation applications or services already offered by the Internet. This new evolution still improves accessibility with the services of the Internet. The migration of the services of the Internet towards the mobile networks, constitutes a major stake of research in telecommunications. The thesis is divided into twomain aims. The first consists to compute the systemcapacity and to evaluate the performances of the UMTS-WCDMA system. Two approaches are used, one is of the spectral analysis, and other one is an approximation of the singular perturbation. The second goal of this thesis is to propose and develop the new mechanisms of call admission control (CAC) for HSDPA and IEEE802.16e networks based on the AMC (Adaptive Modulation and Coding) scheme : the geographical area of the cell is subdivided into several concentric regions. These CAC mechanisms maintain a same QoS (constant bit rate) for all users anywhere in the area of the cell and give priority to migrating or handoff calls by reserving the guard bandwidth than a new call in the intra cell and inter cell mobilities.

Keywords: Wireless networks – Performance evaluation – Resource allocation – Mobility – Call admission control.
