Abstract: A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

Abstract: Disclosed herein are devices, systems and methods for processing remotely at a remote server or cloud platform data relating to emergency communications (phone calls, text messages, etc.) received by Public Safety Answering Points (PSAPs), in particular emergency communications received and handled by emergency communication handling systems at the PSAP which support serial communication and have no network connectivity. To overcome this limitation, one or more serial-to-Internet Protocol (IP) gateways are deployed in the PSAP to: (a) receive the incident data from the emergency communication handling systems and encapsulate the incident data in its raw form in IP packets, and (b) transmit the IP packets to the remote processing system. The remote processing system then parses the incident data according to parsing rule(s) applicable for the PSAP from which the incident data is received, format the incident data and process the formatted data to optimize communication handling operation of the PSAPs.

Abstract: Disclosed examples offer ways to manage dialogues between radio frequency-enabled devices and conserve energy of the devices. A system includes a plurality of radio frequency-enabled nodes networked to communicate with a radio frequency-enabled device. The radio frequency-enabled device includes a radio frequency transceiver and a processing device. The processing device is configured to, in response to expiration of a time period or an occurrence of an event, transition the radio frequency-enable device from a standby mode to a transmit mode. In the transmit mode, a start dialogue message is broadcast. After a pause of a predetermined length following the transmission of the start dialogue message, the radio frequency-enabled device transitions to a receive mode to receive a data packet transmitted from one or more of the radio frequency-enabled nodes. Upon completion of receiving the data packet, the radio frequency-enabled device transitions from the receive mode to the standby mode.

Abstract: When a handover request for performing a handover of a terminal (70) from a macro cell C1 to a CSG cell C2 is received from an SeNB 10 (S8), a base station (TeNB) (40) of the CSG cell C2 transmits a handover response in accordance with a handover enabled/disabled state (S12). The handover response includes an identifier of the terminal (70) in the CSG cell C2. Upon receiving the response, the SeNB (10) notifies the identifier to the terminal (70) (S14). The TeNB (40) repeatedly transmits a dedicated signal containing a handover command via a dedicated channel set using the identifier at an interval shorter than a gap period (S18). Accordingly, whether or not access is permitted can be judged promptly and a smooth handover can be realized.

This allows a communication measure that performs a handover between the 5GS and the EPS smoothly to be provided.

Abstract: A central IoT controller is described for conserving power resources of mobile IoT devices. Specifically, the central IoT controller is configured to at least monitor power reserves of mobile IoT devices, and in response to detecting that a power reserve has fallen below a predetermined threshold, generate computer-executable instructions that adjust configuration settings of the mobile IoT devices to conserve a remaining power reserve. The central IoT controller may modify a check-in interval for mobile IoT devices, configure the transmission of data communications via more power-efficient communication protocols, or reduce the number of active sensors on the mobile IoT device based on proximity to a trusted geolocation or a trusted device. Further, data communications may be rerouted via a proximate trusted device or other proximate mobile IoT device, in response to such device providing an efficiency with respect to available communication protocols.
