In broadband networks for fixed or cellular mobile radio access using the ETSI/BRAN standard, such as UTRANs, Wi-Fi or WLAN wireless communication networks, continuously monitored user equipment positioning data and radio link parameters indicating quality of service of a wireless link between a base transceiver station located in a mobile radio cell of the wireless cellular network and a mobile terminal connected to and being served by the base transceiver station, such as signal-to-noise-plus-interference ratio, power class and bit error rate in uplink and/or downlink direction of the wireless link, may be used for radio cell performance monitoring and/or control. By tracking current positions of user equipment (UE) served by the network, the network can offer location-based services to the UE. A network management system with an integrated alarm signaling unit and having access to a base transceiver station's link performance monitoring system and/or location measurement unit may be used.
