Abstract: The present invention relates to a method and a system for silent and non-exposing alerting of previously abandoned calls. The method and the system handle callbacks in in emergency systems such as Next Generation NG9-1-1 or NG1-1-2 systems with the main focus to avoid exposing people in trouble to a dangerous situation. When abandoned call is detected, verify moving of the calling device and mark as potential victim if not moving. Detect difference in altitude within a time interval of the device and if not large identify other devices in proximity. Send an alert to the proximate devices if it is moving or far enough else send silent alert to the abandoned call device.

Abstract: An audio processing method during a conference comprising capturing a first audio signal and transmitting the first audio signal to a first electronic device by a first terminal device; capturing a second audio signal and transmitting the second audio signal to the first electronic device by a second terminal device; performing signal processing on the first audio signal and the second audio signal to generate a first processed audio signal and transmitting the first processed audio signal to a selected device by the first electronic device, wherein the selected device is one of the first terminal device and the second terminal device; and transmitting the first processed audio signal to a remote system by the selected device. Prevent echo caused by co-located terminal devices emitting sounds at the same time during the conference.

Abstract: This invention is related to a method for locating a first wireless device in an area, the method comprising
receiving a call at an emergency entity coupled to a service operating in a core network, requesting to perform a location estimation of the first wireless device,
determining a set of mobile devices in the vicinity of the first wireless device, said devices being able to perform wireless distance measurements and/or angle estimations,
sending a message each mobile device of the determined set instructing to perform distance measurements with the first wireless device,
receiving results of the measurements.

Abstract: A system and method are provided for recovering a communication session between a client device and a participant device is performed by a server running a central service. The server detects that the client device has lost connection to the participant device and proceeds to maintain the connection to the participant device. In certain embodiments, the server determines why the client device lost connection and selects a second device in close proximity to the client device using information from a user profile associated with the client device. The server then proceeds to establish a connection between the client device and the participant device.
