METHOD AND SYSTEM FOR MEASURING LOCATION USING ROUND TRIP TIME INFORMATION IN MOBILE COMMUNICATION NETWORK
First Claim
1. A system for estimating a position of a mobile terminal, the system comprising:
- a base station configured to compute first round trip time information of a mobile terminal;
a base station controller configured to receive the first round trip time information;
a repeater configured to expand a service coverage of the mobile terminal;
a round trip time measuring unit being in signal communication with the repeater and configured to measure second round trip time information of the repeater; and
a position estimating device configured to estimate the position of the mobile terminal based at least in part on the first and second round trip time information.

Abstract
A method and position estimating system for estimating a position of a mobile terminal is disclosed. In one embodiment, the position estimating system includes i) a base station configured to compute round trip time information of a mobile terminal, ii) a base station controller configured to receive the round trip time information of the mobile terminal, iii) a repeater configured to expand a service coverage of the mobile terminal, iv) a round trip time measuring unit, being connected to the repeater and configured to measure round trip time information of the repeater and v) a position estimating device configured to estimate the position of the mobile terminal by using the round trip time information of the mobile terminal and the round trip time information measured by the round trip time measuring unit. According to one embodiment, a position of the mobile terminal can be exactly computed by using round trip time and information, stored in a network management system.
