Abstract
A method and apparatus are provided for determining information about a cellular mobile radio network comprising a fixed part providing radio coverage in a plurality of cells, and mobile stations for communicating with the fixed part, the network broadcasting to all mobile stations within each cell a frequency allocated to the cell by the network operator and a code allocated to the cell by the network operator. The allocated frequency and code for each cell are determined by monitoring signalling messages passed between network elements, selecting a pair of signalling messages in accordance to predetermined selection criteria, establishing if the pair of messages are related to the same event within the network, and if so, extracting data from the pair of messages. A first embodiment determines the beacon frequency and BSIC of a cell of a GSM type cellular network and associates them with a TRX within the cell. A second embodiment associates the Cell Identity of a cell of a GSM type cellular network with the determined beacon frequency and BSIC.
