Abstract: 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 procedures 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 color, i.e., the more traffic the stronger the color. 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 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.

Abstract: A service of an intelligent network consists of two alternative modes of operation. In a first node of operation, that is, parallel paging, the service does not know at which number the called subscriber can be reached. A paging message is thus transmitted substantially simultaneously to all the numbers determined for the subscriber regardless of which network the number is associated with. The call will be connected to the number at which the call is first answered. In the second mode of operation, that, precision paging, the service knows at which number of the plurality of numbers stored in the database the called subscriber can be reached. The paging message is thus transmitted and the call is thus connected to this number only. It is thus possible to reach a subscriber at a number of a PLMN, DECT or fixed network.
