Evaluation of methods for determining the mobile traffic distribution in cellular radio networks

مقال من تأليف: Collmann, Ralf R. ;

ملخص: Locating the mobile traffic distribution is performed by comparing measured field strength samples with predicted field strength values from a radio network planning tool. The convergence of three approaches has been investigated: Standard Deviation Method, Least Mean Squares Method, and Gauss Probability Method. Improvements like call-by-call evaluation have been introduced to reduce calculation time and to improve the accuracy of the statistical evaluation of the mobile traffic distribution. The methods were verified using field-strength samples and corresponding position data of field measurements made with a vehicle within a mobile network. It has been shown that the accuracy of determining the mobile traffic distribution in this way strongly depends on the reliability of field strength predictions made by a radio network planning tool. With the methods presented in this paper, the creation of traffic databases with a high resolution and the detection of mobile network areas with high traffic load-so-called hot spots-becomes possible.
