Teletraffic issues in mobile communication network planning

In this paper we present an overview of the application of teletraffic meth ods for the planning of mobile communication networks. It is shown that the re is a necessity for an accurate description of the spatial traffic in ord er to perform a demand based planning. To accomplish this task, a new traff ic demand characterization concept based on a pattern of discretized demand nodes is presented. The spatial traffic distribution also plays an importa nt role when designing networks according to new emerging standards like UM TS. Here, novel analytical models for performance evaluation are required, whether for the examination of the interference limited system capacity or the impacts of variable bit rate voice coding on the transportation over th e interconnecting fixed network structure. It is also shown that a spatial characterization of the demand facilitates the application of discrete algo rithms for locating base stations.
