Abstract: An exemplary embodiment discloses a self-aware dynamic authorization method for closed femtocell environments. Initially, a dynamic authorization table is initialized to set authorized records of at least an authorized user equipment (UE) for a closed femtocell. When the closed femtocell provides services for the authorized UE, IMSI/MSISDN records are learned in an initial phase for learning data. The learned IMSI/MSISDN records are dynamically adjusted with the expired period of the access right on the femtocell in a reweighting phase. The expired or oldest IMSI/MSISDN records will be removed from the dynamic authorization table in an ageing phase.

Abstract: Disclosed are an alarm method and system based on voice events, and a building method on behavior trajectory thereof. The system comprises a signal sensor, a voice-event detector and notice and alarm element. In the method, voice signals are captured from a remote unit in an environment. The captured voice signals are classified into at least a voice event. As such, an emergent-event notice is automatically transmitted out if one of predefined emergent events is detected. In the building method on behavior trajectory, messages on voice events are continuously recorded. When the number of the recorded voice events reaches a threshold, a behavior trajectory is constructed, in which a behavior consists of two or more voice events or a single voice event.
