摘要:
Disclosed is a method for interworking between an ACR and a PDE in a position recognition system based on a portable Internet and a system therefor. A scheme for TCP/IP-based socket connection between the PDE and the ACR is defined. A data packet transmitted and received between the PDE and the ACR is also defined so that the PDE can receive a necessary measurement value from the ACR during position determination. The definition of the interworking between the ACR and the PDE serves as a basis for accommodating various services.

Provided are a system and method for determining a position based on portable Internet in a portable Internet system. The method includes receiving, by the terminal, information on neighbor base stations (BSs) from a main BS, scanning the neighbor BSs while measuring Received Signal Strength Indicators (RSSIs) for the main BS and the neighbor BSs, determining whether the RSSI for the main BS is greater than a preset threshold value, and deciding, as a position of the terminal, a position associated with an IDentification (ID) of the main BS when the RSSI is greater than the threshold value.

Provided is a position measuring system and method using a Wireless Broadband (WiBro) signal. The position measuring system measures the position of a terminal using relative delay information that is a parameter of the WiBro signal, used for a hand-over. Since the position of a terminal is measured using a parameter for a hand-over, additional data measurement is not required for the position measurement. Furthermore, efficiency in the use of a parameter of a WiBro system can be improved by using a parameter used only in the hand-over for position measurement.

A function for identifying a current position of a user and providing information about a route to a desired destination is implemented. A mobile communication terminal with a navigation system accurately determines an initial position using a global positioning system (GPS) satellite constellation and a GPS signal intensity and provides a personal navigation service with an improved accuracy.

A positioning system using a mobile Internet signal is disclosed. The positioning system includes access points for transmitting downlink signals for mobile Internet communications, an access terminal for generating positioning information using the downlink signals received from the access points and access point information on the access points, and a position determination entity (PDE) for calculating range values between the access terminal and the access points using the positioning information from the access terminal and determining a position of the access terminal using the range values. Since the positioning system determines the position using the mobile Internet signal, an accurate terminal position can be determined even in such environments as downtown, shaded and indoor areas.
