Modeling of resources for a third generation cellular communication system: an object-oriented approach

A TDMA access system for a Universal Mobile Telephone System (UMTS) has to be adaptive in order to operate in environments with very different constraints (indoor, urban, rural) and to support the integration of voice and data services. Such a system is being studied in the EC project RACE 2084 ATDMA. As to the management and the control of radio resources, a combination of techniques such as dynamic resource allocation, dynamic channel allocation, packet access and frequency hopping is considered. Mostly, these different control techniques are evaluated independently. The global system simulator of the ATDMA project evaluates the interaction of the different resource allocation techniques. The paper analyses and models the resources for the simulator using object-oriented modeling. The authors discuss how the allocation techniques operate on the resources
