Problems solved by technology

[0010] However, in a WiBro network, the GPS signal may not be received in the city center or in the dead zone of the building, and it is difficult for the PSS to receive signals from multiple RAS
Also, the time delay caused by the repeater is greater than the time delay caused in the wireless segment
Also, since the RAS cannot distinguish between the signal sent from the transponder and other signals, it is difficult to accurately measure the time delay
Therefore, accurate positioning is difficult

Embodiment Construction

[0028] Exemplary embodiments according to the present invention will now be described in detail with reference to the accompanying drawings.

[0029] figure 1 is a WiBro network according to one embodiment of the present invention, wherein Mobile Subscriber Stations (PSS) communicate with repeaters and Radio Access Stations (RAS).

[0030] There are multiple RASs 110-1 and 110-2, multiple repeaters 120-1 to 120-3, and PSS 130 in the WiBro network. exist figure 1 , the PSS 130 communicates with the RAS 110-1 through the repeater 120-1.

[0031] Figure 2A and 2B It is a system block diagram according to an embodiment of the present invention, wherein the position positioning module is provided in the transponder or connected to the transponder to locate the position of the PSS.

[0032] refer to Figure 2A , providing a location calculation module 210 and a location location module 230 to locate the location of the PSS. The position location module 230 is included in the t...

Abstract

Disclosed is a method and apparatus for positioning a portable subscriber station (PSS) using a WiBro repeater, and a repeater having the apparatus. The method of positioning the portable subscriber station in a network having a radio access station (RAS) and a repeater, includes the steps of: detecting a preamble signal transmitted from the RAS; generating a reference time by measuring a receiving time of the preamble signal and by compensating the receiving time of the preamble signal by taking into consideration a signal delay time between the RAS and the repeater; measuring a receiving time of a ranging signal received from the PSS on the basis of the reference time; and calculating the receiving time of the ranging signal by using a time stamp generated on the basis of the receiving time of the preamble signal.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 682,470 filed with the United States Patent and Trademark Office on May 19, 2005, and Korean Patent Application No. 2005- 60767, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a location-based service (LBS) in a WiBro network, and more particularly to a method and apparatus for positioning a mobile subscriber station (PSS) by using a WiBro repeater, and its repeater. Background technique [0004] Wireless broadband (WiBro) Internet service or mobile Internet service provides high data rate wireless Internet access through mobile subscriber stations (PSS) anytime and anywhere in a static or mobile environment. More specifically, the term "Stationary or mobile" means that Internet access service is provided while the user is standing, walking or moving at a moderate speed such as up to 60Km / h...
