<p>A traffic management system reads TT files obtained from Mobile Services Switching Centers, and processes information included in the records of the files, and on the basis of the information produces a hierarchical graphic representation on a map display. The highest level represents the operator's entire service area, and the lowest level a cell. On each level, traffic intensity is displayed with grades of colour, i.e. the more traffic the stronger the colour. The display is updated automatically as the MSC provides the TT data. The system monitors traffic load in the cells. If the traffic load in any one of the cells exceeds a preset level, the system automatically transmits a command to the MSC to change the logic size of the cell or add a TRX unit, if such is available.</p> |
