The present invention relates to a mobile communication system for executing a hybrid location service in an LBS network and a control method thereof. In particular, an SLP server located at a lower level of an LM server in an LBS network performs positioning with a terminal while simultaneously surrounding a terminal. It collects AP (access point) information and passes it to the WPS server, and the WPS server also uses the AP information collected by the SLP to simultaneously perform location positioning with the SLP to calculate the position value of the terminal in a hybrid manner. The present invention relates to a mobile communication system for executing a hybrid location service and a control method thereof.

In general, LBS (Locationin based service) network refers to the application systems and services that accurately identify and utilize the location of a person or thing based on a mobile communication network. In the LBS network as described above, the current positioning technology is progressed in three ways: using an existing network, using a unique new network, and using a GPS. In addition, the general method of performing the wireless positioning for the technology development method may be classified into a network based method, a handset based method, and a hybrid method using a mixture thereof. For this method, the positioning method can be generally classified as follows. First, AOA (Angle of Arrival) method of measuring the angle of arrival of the signal from the base station to the terminal, and TOA (Time of Arrival) method of measuring the propagation time by using the arrival time of the radio wave. And TDOA (Time Difference of Arrival) method that uses the relative difference of radio wave arrival time from two base stations, GPS method (WAG: Wireless Assisted GPS) to determine location by attaching GPS to the terminal, and location using radio camera. Determining a frequency pattern matching method (LPM: Location Pattern Matching).

Then, referring to FIG. 1, an example of a conventional hybrid location service providing system applied to an LBS network as described above is connected to a communication network 70 and is connected to a GPS / WiFi terminal 71 through a wireless communication channel. A radio network device (72A-N) for processing radio call signals;

Alternatively, the GPS / WiFi-compatible terminal 2 may be various mobile terminals connected through a wideband LAN (WLAN).

Next, the control method of the present invention having the above configuration will be described.

In the OMA SUPL V2.0 based message created by the SLP server after the positioning simultaneous execution command process (S5) for positioning using the GPS from the GPS / WiFi terminal which has been requested for positioning via the wireless network device. Receives and calculates the corresponding message signal including AP information around the terminal and transmits the calculated GPS using positioning signal to the LM server. At the same time, the WPS server is bypassed from the SLP server 5. Performing a location checking procedure (S6) of calculating a location using AP information around a terminal included in an OMA SUPL V2.0 based message and then transmitting the calculated WiFi signal using a location signal to an LM server;

After the positioning procedure execution process (S6), the LM server performs the positioning process at the same time to calculate the position result value by processing the positioning signal using the GPS of the SLP server and the positioning signal using the WiFi signal of the WPS server in a hybrid manner. Then, the location information processing step (S7) of transmitting the calculated result to the corresponding terminal requesting the location confirmation; is configured to include.

At this time, when the LM server 4 does not receive a message requesting the location confirmation of the specific GPS / WiFi terminal 2 from an arbitrary terminal 7, the LM server 4 executes other general functions, for example, a standby mode. .

However, at this time, if a message for requesting the positioning of a specific GPS / WiFi terminal 2 is received from any terminal 7 during the above process, the LM server 4 may use the specific GPS / WiFi combination included in the request message. Based on the ID of the terminal 2, the SLP server 5 and the WPS server 6 are required to simultaneously execute positioning.

Then, the SLP server 5 which has received the simultaneous positioning command as described above is first used for positioning the GPS / WiFi terminal 2 using the GPS as the location request requested via the wireless network device 3A-N. In addition, AP information around the terminal is also required to be transmitted in the OMA SUPL V2.0 based message. After the above process, if the terminal 2 also loads the AP information around the terminal in the OMA SUPL V2.0 based message which is prepared after the positioning using the GPS, and transmits it to the SLP server 5, the SLP The server 5 receives the calculated message signal, calculates it, and then transmits the calculated GPS using positioning signal to the LM server. At the same time, the SLP server 5 transmits AP information around the terminal included in the message to the WPS server ( 6) bypass (or pass over).

Then, the WPS server 6 simultaneously uses the WiFi signal using positioning information by using AP information around the terminal included in the OMA SUPL V2.0 based message bypassed from the SLP server 5. After calculating the and transmits the information to the LM server (4).

On the other hand, after the positioning process as described above, the LM server 4 hybridizes the positioning signal using the GPS of the SLP server 5 and the WiFi signal using the WiFi signal of the WPS server 6 received by performing the positioning process at the same time. The position result value is calculated by the method, and then the calculated result value is transmitted to the corresponding terminal 7 requesting the position confirmation through the communication network 1.

Therefore, according to the method of the present invention as described above, the SLP server proceeds with the positioning of the terminal without going through a complicated execution procedure for positioning, and collects AP (Access point) information around the terminal and hands it over to the WPS server. Since the server also uses the AP information collected by the SLP to simultaneously perform positioning with the SLP, only one process is easily performed between the GPS / WiFi-compatible terminal and the SLP server. Even if the location request signal is increased in a large amount, it can be easily adapted to the corresponding service development.
