Tool Development for Analysis of WCDMA Radio Measurements and Investigation of EcNo and RSCP values before Drop Call

摘要

In this work, a tool was developed for the post processing analysis of the drive test measurement files. This tool collects all the necessary information from measurement files and organizes this information to a data base. The tool plots of the Received Signal Code Power (RSCP) measurements on the map along the route of the car, using a color code. The RSCP measurement can be either the RSCP of the best server or the RSCP of a certain Cell. Moreover, a very important plot is also available, the plot which shows where are the interference measurement samples on the map. Finally, an investigation of the EcNo and RSCP values exactly before drop call was done using a large list of measurement files, in order to optimise operator's parameters of the handover algorithm.
