摘要:
Provided are a method for detecting a received signal and an apparatus for detecting a satellite navigation received signal using the same. The present invention provides cells where a correlation value obtained through parallel signal detection is a predetermined signal detection threshold value or more are selected and time domain correlation is performed on the cells so that the correlation value is verified. The cells having the predetermined verified threshold value or more are detected as a final received signal.

The present invention relates to a terminal and a terminal location providing method. The terminal for selectively accessing a plurality of base stations supporting different communication systems includes a first network interface card that is turned on when the terminal is turned on, a second network interface card that is turned on or activated when receiving the terminal's location information request, a power controller for controlling power of the first and second network interface cards, and a processor for receiving the terminal's location information request and controlling the power of the first and second network interface cards through the power controller.
摘要:
An apparatus for determining a position of a terminal calculates distances between a terminal and a plurality of base stations by using time information acquired by a reference station among the plurality of base stations through unidirectional communication between the terminal and the base stations and between the base stations, and determines a position of the terminal by using the calculated distances.

摘要:
A method and system of preventing a loss/theft using a wireless personal area network (PAN) or a wireless local area network (LAN) which can receive, from a mobile device included in a surveillance target via a gateway, a location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile: device information being collected by a; sensor of the mobile device, and signal information communicated between the mobile device and a fixed device, can determine whether there is a loss or a theft by comparing surveillance target information and a permission standard, and can provide alert information including the location information of the surveillance target when there is the loss or the theft is provided.
摘要:
An apparatus for sharing Web contents is provided. The apparatus includes a Web browser that loads and outputs a Web page, and a Web content transmission client that is linked with the Web browser to extract context information that is current state information from the Web page, and transmits the extracted context information to at least one other terminal.

Disclosed are a method and system for connecting lower nodes to one another to increase scalability in a ZigBee network. The method includes approving a participation request to excess lower nodes requesting participation in higher nodes where network addresses set with respect to the higher nodes are allocated to all of the lower nodes; when a transmission message is received from the excess lower nodes, analyzing the received transmission message and determining a node for transmitting the transmission message; and transmitting the transmitted transmission message to the determined node.
摘要:
There is provided to a method for avoiding indirect collision of beacon, including: collecting beacon information of neighboring nodes and allocating a time slot based on the collected beacon information; transmitting information on the allocated time slot to the neighboring nodes depending on time slots of the neighboring nodes; and checking whether the time slot overlaps based on a reply message from the neighboring nodes and reallocating a time slot upon occurrence of overlapping.
摘要:
Provided is a method of managing addresses of incommunicable nodes in a ZigBee network, and more particularly, a method of managing address values of a plurality of nodes that form a ZigBee network by efficiently withdrawing address values from nodes which are incommunicable for reasons of abnormality. An address management process can be performed using two methods. According to a first method, a parent node withdraws address values of child nodes that do not transmit a hello message for a predetermined period of time. According to a second method, a parent node transmits a periodic or non-periodic request message to child nodes, and the child nodes, which receive the request message, immediately transmit a hello message to the parent node. Then, the parent node withdraws address values of child nodes that do not respond to the request message sent by the parent node more than a predetermined number of times. An address value assignment process and a process for nodes that have their address values withdrawn are also provided.
