Abstract
A method and apparatus are provided for monitoring a cellular mobile radio system and for identifying monitored radio elements within the network with respect to other network entities. The logical and physical topology of a cellular mobile radio system is determined by monitoring messages passed across a communications interface in the system. Embodiments of the invention associate common information occurring in different messages, and over time, establish the topology of a network, even though messages passed across the monitored interface do not comprise unique system-wide addressing information. In particular, the present method provides a mapping between radio elements (TRX) and other network entities (TEI, CI, and LAI) in a GSM type cellular system by monitoring messages across the Abis and A interfaces.
