Abstract: An active data collection mode control system to reduce crowd sourcing signal data collection required for fingerprint database (FPDB) maintenance is provided. The system includes a mobile device that supports a survey mode, a localization mode, and a crowd-sourcing mode, and a server that receives data from the mobile device, generates and updates an FPDB, and controls a data collection mode.

Abstract: Provided herein is a link management method and apparatus in a multi-layered network, the method including confirming whether or not set virtual TE link resources can be committed to a virtual TE (traffic engineering) link; in response to the set virtual TE link resources being committable to the virtual TE link, committing the resources to the virtual TE link through resource commitment; in response to the set virtual TE link resources being not committable to the virtual TE link, determining whether or not the virtual TE link is an adaptive virtual TE link; and in response to the virtual TE link being determined as the adaptive virtual TE link and the adaptive bandwidth satisfying TE link setting standards, committing the resources to the virtual TE link.

Abstract: Provided is an atypical environment-based location recognition apparatus. The apparatus includes a sensing information acquisition unit configured to, from sensing data collected by sensor modules, detect object location information and semantic label information of a video image and detect an event in the video image; a walk navigation information provision unit configured to acquire user movement information; a metric map generation module configured to generate a video odometric map using sensing data collected through a sensing information acquisition unit and reflect the semantic label information; and a topology map generation module configured to generate a topology node using sensing data acquired through the sensing information acquisition unit and update the topology node through the collected user movement information.
