Communication connection detection system for global satellite mobile communications network

摘要

The connection detection system uses a detection device (M,...), provided by a standard peripheral and/or a recording device (STR) for the transmitted information, inserted in the connection path when a call is placed from a specific subscriber (a), or placed to a specific subscriber (B). The encoded information transmitted along the established connection is decoded at the detection device and recorded when the subscriber identification data corresponds to subscriber identification data provided by an authentification centre register. Pref., the detection device is connected to the exchange handling the calls for the monitored subscriber.
