Abstract: A radio service and more particularly for multimedia services, the availability of the resources often fluctuates, according to the load, mobility of users and variation of the transmission quality. The fluctuation is a major problem for radio network operators to adapt the use of the resources considering the mobility of the users. The allocation of the bandwidth of various types of traffic is done only at fresh call arrival or for a handover. The mobility of the users has an important influence on the configuration of the network. Such intercellular handover modifies the distribution of the traffic in the system and generates additional signalling load. In this study, we consider the mobility of the users in the dimensioning network and four traffic models (voice, video, www and ftp). This mobility model allows us to determine at the cell level as well as at the entire system level, for QoS parameters, threshold values beyond which a call can be blocked.

Keywords: multimedia; mobile radio networks; mobility model; traffic models; system planning; QoS parameters; wireless networks; quality of service; call blocking.
