摘要:
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:
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.
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:
Provided is a method for estimating a position of a mobile terminal in a wireless network. In the method according to the present invention, difference values between squared signal arrival times of base stations are used to estimate the position of the mobile terminal.
摘要:
A terminal location measuring device includes a database for storing registration information of a plurality of access points (AP's) forming a first infrastructure system for wireless LAN-based indoor location determination. The terminal location measuring device sets a search range of a database by using location information of the terminal acquired through a second infrastructure system that is different from the first infrastructure system, an identifier of at least one of a plurality of AP's, and a signal measurement value. The terminal location measuring device extracts registration information of an AP having the same identifier as at least one AP within the search range of the database, and measures a location of the terminal by using registration information of the AP.
