Traffic model for multimedia mobile radio communications

Currently, 3G mobile radio communications (IMT-2000) are being introduced for application to multimedia signal transmission. User movement and multimedia traffic have a great impact on networks. A traffic model for the multimedia signal is necessary for the design of a mobile radio communication network. However, no traffic model has yet been proposed that takes into account both the effect of multimedia signal transmission and inter-cell user mobility. This paper describes a traffic model that takes the effect of multimedia services and the user mobility of a mobile communication network into consideration. After giving the mobility model and multimedia signal characteristics, the relationship between the amount of multimedia traffic and call loss probability as well as the relationship between user mobility and call loss probability are clarified by computer simulation. As a result, we found that it is important to consider both user mobility and multimedia traffic in designing a mobile radio communication network.
