In mobile environments, packet transmission services suffer from packet losses due to e.g. inadequate received signal quality, or forced by protocols in the signaling domain of the infrastructure of a mobile communications network. To reduce the occurrence of packet losses and, hence, to improve the quality of packet transmission services, such as e.g. the Short Message Service (SMS) deployed in GSM (Global System for Mobile Communications) based mobile communications networks, a quantitative analysis of the Quality of Service (QoS) in the signaling domain is mandatory. In this communication the authors propose software architecture for QoS monitoring in distributed SMS Centers. Operating in near real-time, this helps to maintain a high QoS level. Selected monitoring results gathered during real world network operation are presented.
