First Claim
1. A network management system having access to a link performance monitoring system and a location measurement unit, both of a base transceiver station, the location measurement unit being used for detecting current positioning information signals which are transmitted from user equipment via a wireless interface of a cellular wireless communication network to the base transceiver station of the cellular wireless communication network, said network management system comprising:
- an integrated alarm signaling unit generating a warning message or alarm signal if at least one continuously monitored radio link parameter indicating quality of service in uplink and/or downlink direction of a current wireless link established between the base transceiver station and the user equipment, when the user equipment is moving, becomes worse than a predefined threshold value, and the at least one continuously monitored radio link parameter is derived from a current measurement of at least one positioning information signal transmitted from the user equipment to the base transceiver station.

Abstract
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.
