The present invention relates to a method and system for positioning a mobile communication terminal.

As computers, electronics, and communication technologies have advanced dramatically, various wireless communication services using wireless networks have been provided. Accordingly, a service provided by a mobile communication system using a wireless communication network is developing into a multimedia communication service for transmitting data such as circuit data, packet data, and the like, as well as voice service.

Among various wireless Internet services using a mobile communication terminal, in particular, a location based service (LBS) has gained much attention due to its wide utility and convenience. The location-based service refers to a communication service that locates a mobile communication terminal such as a mobile phone and a personal digital assistant (PDA) and provides additional information related to the identified location. Location-based services can be applied to a variety of areas, including rescue requests, response to crime reports, geographic information systems (GIS) for providing information on neighboring areas, traffic information, vehicle navigation and logistics control, and customer relationship management (CRM). Can be used.

The location measurement service for providing a location based service (LBS) is a network based software that uses a radio wave environment that is a cell radius of a base station of a mobile communication network to measure a location of a mobile communication terminal. Based method, handset based method using a GPS (Global Positioning System) receiver mounted in a mobile communication terminal, and hybrid (Hybrid) method that combines these two methods.

Handset based methods include A-GPS and E-OTD. A-GPS is available in both European GSM-based networks using TDMA and IS-95-based network technologies using CDMA. In the CDMA wireless access method, the position of the terminal is determined by sending and receiving messages through the IS-801-1 interface between the mobile communication terminal having the GPS receiver and the position calculation server in the CDMA network. At this time, the signals received from the GPS satellites are received with four or more satellite signals, so positioning is very accurate.

The A-GPS is a location calculation server that calculates a location by receiving satellite signals received from a mobile communication terminal and a location information center (MPC) that links calculations based on base station information in a mobile communication network to other systems. Consists of

The A (Assisted) -GPS method uses a long time to first fix (TTFF) in the C-GPS method, and it is difficult to locate due to obstacles in buildings or skyscrapers. Receiving the aiding data and positioning more quickly and accurately. To this end, the mobile communication terminal and the mobile communication network transmit and receive messages using the protocol defined in the IS (Interim Standard) -801-1 standard.

Enhanced Observed Time Difference (E-OTD) is standardized through LCS Releases 98 and 99 at the GSM Standards Committee for TDMA-based GSM, which uses the TDMA radio access standard. The mobile communication terminal determines a position by calculating a difference between a relative arrival time and a distance of signals received from three or more base stations. The EOTD method uses a combination of OTD, RTD (Real Time Difference) and GTD (Geometric Time Difference) methods. The OTD method calculates the signal arrival time from two base stations from the base station to the terminal, and the RTD method calculates the difference between the signal transmission start time at the two base stations. In addition, the GTD method calculates the distance difference between the two base stations by calculating the distance between the base station and the terminal.

The network-based location measurement technology transmits data (PPM, OTD, etc.) measured by the terminal to the positioning server according to the protocol (IS-801, RRLP, RRC, etc.) promised between the mobile communication terminal and the server. (PPM, OTD, etc.) performs the location measurement function of the mobile communication terminal in the positioning server. The positioning server performs network location measurement (a method of positioning a location of a terminal requested for positioning at a server side except for a positioning method using GPS satellites) and sends the result to an object requesting a positioning service (MPC, CP (Contents Provider) Or service requesting terminal).

The network-based position measurement technology uses the cell ID method using a base station radius cell and AOA (Angle Of Arrival) that calculates a position by calculating a line of bearing (LOB) while receiving a signal transmitted from a mobile communication terminal. ), TOA (Time Of Arrival) method that calculates the position at the mobile communication terminal by the arrival time of radio waves launched between three or more base stations, and arrival of pilot signals received from three base stations at the mobile communication terminal. A time difference of arrival (TDOA) method is used to determine a point where two hyperbolas intersect by measuring a time difference and calculating a distance difference between base stations as a location of a mobile communication terminal.

However, the conventional location information collection method has a disadvantage in that it is difficult to collect location information from the mobile communication terminal when the mobile communication terminal is located in a shaded area or a place inside a building.

In order to solve the above problems, the present invention, in the process of locating the position for the None GPS terminal, when receiving a radio environment request message from the mobile communication switching station establishes a traffic channel with the mobile communication terminal, from the mobile communication terminal After receiving the radio environment measurement response message, it generates and transmits the radio environment response message, and when receiving the location request message from the indoor location-based service providing server, generates and transmits the location response message and transmits the message to the gateway mobile location center.
