Abstract: A terminal device is configured to perform a method for identifying a target device in a local area network (LAN) comprising a plurality of potential target devices. The method includes communicating in an omni-directional format to obtain discovered devices within the area, communicating in a narrow beam format in a direction of the target device; identifying a first list of a first plurality of devices including the target device; eliminating a device from the first list of devices to create a second list of devices; calculating a distance between the terminal device and each device in the second list of devices; determining a precise distance between the terminal device and the target device using a precise distance measurement method; determine which device of the second list of devices has a distance that compares favorably to the precisely determined distance; and identifying the device ID.

Abstract: A method performed by a notification system for selecting notification recipients that are to receive abnormal event information. The method comprises storing abnormal event information including at least one of an event identifier, location, speed, direction and road information in a memory of the notification system; determining, by a processor of the notification system, a latest potential impacted area (PIA) based on the abnormal event information; creating a list of potential recipients within the latest PIA; selecting from the list of potential recipients a recipient to be notified according to a selection criterion specified in the memory, wherein the selection criterion is based on potential recipients information, including at least one of notification configuration, notification log, location, speed, direction and behavior history of the potential recipients; and sending, by a transmitter of the notification device, an abnormal event notification to the selected recipient.
