Abstract:
An apparatus, system and method for managing radio resources are disclosed. The apparatus for managing radio resources includes a media independent services (MIS) user unit, a link layer unit, and a media independent services function (MISF) unit. The link layer unit outputs its own link status and radio resource allocation status. The MISF unit receives a report on the link status and radio resource allocation status from the link layer unit, receives a report on link status of a terminal from the corresponding terminal, receives a report on link status and radio resource allocation status of a neighboring Point of Attachment (PoA) from the corresponding neighboring PoA, and receives network configuration information from a network configuration information server. The MIS user unit determines to change radio resource allocation based on information from any one of the link layer unit, the terminal, the neighboring PoA and the network configuration information server.
Abstract:
Provided are an object tracking system and an object tracking method. The object tracking system includes: a terminal identifier and reference time providing module configured to receive an identifier of a terminal and a reference time for tracking an object corresponding to the identifier; a cross-CCTV detection module configured to detect a cross-CCTV for the terminal by using a CCTV installation information and a location of the terminal before the reference time; a basic image detection module configured to detect an object repeatedly appearing in the cross-CCTV as a basic image; a current-CCTV detection module configured to detect a current-CCTV currently recording the terminal by detecting a location and a moving direction of the terminal after the reference time; an object detection module configured to detect an object appearing in the current-CCTV based on the location and the moving direction of the terminal after the reference time; and an object tracking module configured to track an object corresponding to the identifier by determining whether the detected object from the current-CCTV and the basic image.
Abstract:
Single radio handovers (SRHOs) between heterogonous networks can be facilitated using several techniques. One such technique includes activating a receiver of a target radio interface in a mobile node without activating a transmitter of the target radio interface, thereby allowing the mobile node to perform target network discovery while the transmitter of the target radio interface remains deactivated. Another such technique includes encapsulating link-layer discovery frames into media independent handover frames (MIH), and then tunneling the MIH frames over a tunnel extending through the source network. This may allow the MN to achieve various handover related tasks without activating the target radio link. Another technique includes establishing a schedule (or delay period) for synchronizing deactivation of the source radio interface with activation of the transmitter in the target radio interface.
Abstract:
Provided is a report data convergence analysis method for a disaster response. The method includes receiving first input data including report input data of a reporter, reception input data of a receiver, and report document input data that is prepared by the receiver after a disaster situation ends, storing the first input data in a first database, generating a plurality of first learning models through a learning process based on the first input data stored in the first database, and when the report input data of the reporter is received, performing convergence analysis on the plurality of generated first learning models to provide disaster situation information.

Abstract:
A method for establishing a network connection includes determining a list of access networks detectable by a user equipment, and reducing the list of access networks to a list of preferred networks in accordance with supplemental information associated with the user equipment. The method also includes selecting a first candidate network from the list of preferred networks, and attempting to connect to the first candidate network.
Abstract:
The present invention relates to a method of providing proximity service communication between terminals. In accordance with an embodiment, a first terminal makes connection to a second terminal with network assistance. The first terminal requests information required to search for the second terminal from a network management server. The network management server determines a communication mode for proximity service communication. The network management server transmits a request message requesting communication between the first terminal and the second terminal in the communication mode to the first and second terminals. In accordance with another embodiment, a first terminal may switch its proximity service communication technology for better QoS without network assistance. The first terminal monitors link status. If the link status is deteriorated, the first terminal requests a second terminal to change proximity service communication technology. The first and the second terminal switch their proximity service communication technologies.
