Location of origin of measuring data for radio characteristics of cellular network

摘要

The measured values from the interface (Abis1) are recorded with a protocol analyser (2) and stored in a memory device or a database (3), so that they can be selected by the software (4) and sorted in the measuring vector bank (5). From the operation and maintenance controller (OMC) (6) the neighbourhood list of the server base station can be determined and stored in a memory device or database (7). From the list can be obtained the location, the elevation and the land utilisation data (8, 9). From the field strength unit (10) can be deduced the prediction data (11) and the predicted reception strengths for the server and neighbouring stations (20,...), together with the vector data (12, 12). The steps in the calculation involve the determination of the transmit times for signals in the cellular network, the determination of the transmitter parameters for at least one stationary transmitting and receiving units, and the prediction of the transmitting parameter.
