Furthermore, the positioning device may further include some or all of the GPS satellite 120, the wired / wireless communication network 130, the AP usage pattern analysis server 160, and the LBSP 170.

In an embodiment of the present invention, the communication terminal 100 may be applied to various wired and wireless environments, and may be classified into a personal digital assistant (PDA), a cellular phone, a smart phone, etc., which are classified by terminal type, and a personal communication service (PCS), which is classified by communication method. A phone, a Global System for Mobile (GSM) phone, a Wideband CDMA (W-CDMA) phone, a CDMA-2000 phone, and a Mobile Broadband System (MBS) phone may be included. Here MBS phone represents a communication terminal 100 to be used in the next generation system currently being discussed. Furthermore, the communication terminal 100 according to the embodiment of the present invention may further include a desktop computer, a laptop computer 103, and the like.

The communication terminal 100 may include a wireless communication module and a wireless LAN module, and further include a GPS module. As the wireless communication module is provided, the communication terminal 100 connects to the wired / wireless communication network 130 to perform normal voice call and data communication with the other party. In addition, the communication terminal 100 may receive various web page data by accessing the wired / wireless communication network 130 via the AP 110 recognized around the wireless LAN module. Furthermore, the communication terminal 100 may be divided into a GPS terminal 101 and a non-GPS terminal 102 according to whether a GPS module is provided, and when the GPS module 120 is provided, data provided through the GPS satellites 120.

Among the Internet access protocols used by the communication terminal 100, MIE uses m-HTML, which is shortened by slightly modifying HTML, and in the case of i-Mode, a language called compact HTML (c-HTML), which is a subset of HTML, is used. use.

Recently, a communication terminal 100 such as a smartphone 100 uses a browser for a wireless Internet access of a specific communication company such as Opera Mini for the iPhone to provide a faster wireless Internet, or in connection with the communication terminal 100 Local area networks such as Wi-Fi and WiBro are also used to provide wireless high-speed Internet.

The communication terminal 100 performs network-based positioning or handset-based positioning according to a positioning request from the positioning server 140. For example, the communication terminal 100 may provide GPS information, base station information, and AP information to the positioning server 140 via the wired / wireless communication network 130 to perform network-based positioning. As described above, when performing network-based positioning, a positioning protocol message of a specific standard is used between the communication terminal 100 and the positioning server 140. Here, the positioning protocol is a standardized standard of the application layer for positioning of the communication terminal 100.

For example, when the wired / wireless communication network 130 is an asynchronous (WCDMA) network as shown in FIG. 2, the GPS terminal 101 capable of receiving a GPS signal includes positioning information requested by the positioning server 140, such as GPS information and base station information. And using a Secure User Plane Location (SUPL) message to provide the AP information, and the non-GPS terminal 102, which is unable to receive a GPS signal, provides location information requested by the positioning server 140, for example, base station information and AP information. PCAP (Positioning Calculation Application Part) message is used to provide. In the case of a synchronous (CDMA) network, the GPS terminal 101 provides location information to the positioning server 140 using an Interim Standard-801 (IS-801) message, and the non-GPS terminal 102 provides a PSM ( Location information is provided to the location server 140 using a Pilot Strength Measurement) message. Here, since the GPS terminal 101 may use various positioning protocols such as RRLP (Radio Resource Location Services Protocol) and RRC (Radio Resource Control) in addition to SUPL and IS-801, it will not be particularly limited to such a positioning protocol.

In the case of the synchronous type, the positioning information provided by the GPS terminal 101 to the positioning server 140 through the IS-801 message includes system information currently being serviced, a pilot signal of an adjacent base station, signal strength (Ec / lo), and the like. Here, the system information includes, for example, a system ID (SID), a network ID (NID), a base station ID (BSID), a base station sector number (Ref_PN) currently being serviced, a pilot phase and signal strength in Ref_PN, and the like. In addition, the pilot signal of the neighbor base station includes a neighbor base station sector number (Measurement PN) collected from the GPS terminal 101, a pilot phase and signal strength in each neighbor base station sector number, and the like. If it is asynchronous, the positioning information provided by the GPS terminal 101 through the SUPL message is MCC (Mobile Country Code), MNC (Mobile Network Code), UC-ID, PSC (Primary Scrambling Code), RSCP (Received Signal Code Power). ), The signal strength (Ec / No), the observed time difference between the system frame number (SFN), or the time difference between the transmission and reception (RX-TX) of the GPS terminal 101, and so on. The example may include location related data used in all other communication systems, without being limited thereto. Of course, the non-GPS terminal 102 also provides positioning information to the positioning server 140 via a PCAP message or a PSM message, which is almost the same as the positioning information that the GPS terminal 101 provides to the positioning server 140.

When the GPS terminal 101 performs positioning using a SUPL or IS-801 message at the request of the positioning server 140, a positioning message (hereinafter, referred to as a first positioning message) as the SUPL message is shown in FIG. 2. When the wired and wireless communication network 130, for example, NodeB (200), RNC (210) and MSC 220, such as pass through each network node safely, while the non-GPS terminal 102 is a PCAP or PSM message When the positioning is performed using the first positioning message, the positioning message (hereinafter referred to as the second positioning message), such as a PCAP message, is called through all the network nodes. The call may be processed quickly.

The AP 110 includes a small base station, such as a femto or pico base station, which is frequently installed in a building. Here, the femto or pico base station is classified according to the maximum number of communication terminals 100 can be connected according to the classification of the small base station. In addition, the AP 110 includes a short-range communication module for performing short-range communication such as the communication terminal 100 and Wi-Fi. In the embodiment of the present invention, short-range communication is RF and ultra-wideband communication such as Bluetooth communication, Zigbee communication, infrared communication (IrDA), Ultra High Frequency (UHF) and Very High Frequency (VHF) in addition to Wi-Fi. (UWB) and the like can be carried out in various standards. Accordingly, the AP 110 may extract the location of the data packet, designate the best communication path for the extracted location, and forward the data packet to the next device, such as the communication terminal 100, along the designated communication path. The AP 110 may share several lines in a general network environment, and may include, for example, a router, a repeater, a repeater, and the like. In addition, bridge products from certain manufacturers, such as KT's eggs or Verizon's MiFi, may also be included in the AP 110.

The AP 110 is largely divided into a fixed AP 111 and a mobile AP 112. The fixed AP 111 may include a router, a repeater, a repeater, and the like, and the mobile AP 112 includes a bridge product of a specific manufacturer such as MiFi of Verizon, USA. The mobile AP 112 may guarantee free mobility and, for example, read a receiving side address of the communication terminal 100 from the transmitting side information transmitted through the wired / wireless communication network 130, and then designate the most appropriate communication path, and then transmit the same.

Although the AP 110 is illustrated as being configured separately from the wired / wireless communication network 130 in FIG. 1, the AP 110 may be included in the wired / wireless communication network 130, and thus the present invention is specifically limited thereto. I will not.

The wired / wireless communication network 130 includes a synchronous (CDMA) network, an asynchronous (WCDMA) network, a GSM network and a Long Term Evolution (LTE) network as a wireless communication network, and includes a public telephone network (PSTN) and an internet network as a wired communication network. It may include. In the embodiment of the present invention, if the location information from the communication terminal 100 can be transmitted to the positioning server 140, any communication network may be used, and thus the present invention is not particularly limited to the above communication network.

Among them, for example, in the case of the WCDMA network illustrated in FIG. 2, the NodeB 200, the Radio Network Controller (RNC) 210, the Mobile Switching Center (MSC) 220, and the Serving GPRS Support Node (SGSN) are provided. 250 may be included. The WCDMA network may further include a Home Location Register (HLR) 230 and a Visitors Location Register (VLR) 240. Here, the RNC 210 relays voice or data calls between the NodeB 200 and the MSC 220 or between the NodeB 200 and the SGSN 250. Of course, the NodeB 200 and the RNC 210 in the WCDMA network may be replaced by a base station transmission system (BTS) and a base station controller (BSC) in the case of the CDMA network. In addition, in an Evolved Packet Core (EPC) network, an evolved base station (e-NodeB) and a mobility management entity (MME) may be replaced. The MME is an integrated form of the RNC 210 and the MSC 220 in the WCDMA network. The RNC 210 and the MSC 220 perform almost the same role.

The NodeB 200 is arranged in each cell unit, for example, receives a call request signal from the communication terminal 100 through a traffic channel among signal channels, and receives the received call request signal from the RNC. The location registration is performed to determine the location of the communication terminal 100 which is transmitted to the 210 or exists in the cell area under its control. In addition, the NodeB 200 is a network endpoint device directly connected to the communication terminal 100 to perform baseband signal processing, wired / wireless conversion, and transmission and reception of a wireless signal. NodeB (200) is a communication terminal 100 located in its cell area if the call is received if the location of the communication terminal 100 after the call from the MSC 220 through the RNC 210 Send the request signal.

In addition, the NodeB 200 may obtain information such as the latitude and longitude of the location of the NodeB 200 using a signal from the GPS satellite 120, and transmit the location information of the NodeB 200 through a system parameter message of the forward link call channel. It may be delivered to the communication terminal 100. The communication terminal 100 may register new location information by calculating a moving distance of the communication terminal 100 itself using the location information of the NodeB 200 of the cell to which the communication terminal 100 belongs. Here, the location registration is a processing procedure for notifying the MSC 220 of the location, status, identifier, slot period, and other characteristics of the communication terminal 100 through the NodeB 200, and the NodeB 200 communicates with the communication terminal 100. This is a procedure for effectively calling the communication terminal 100 when trying to set the received signal. The location registration of the communication terminal 100 may be performed when the power of the communication terminal 100 is turned on or off, when the communication terminal 100 moves between the MSCs 220, and the communication terminal 100. May be implemented in the case where the parameter of.

The RNC 210 controls the NodeB 200, allocates and releases radio channels to the communication terminal 100, controls transmission output of the communication terminal 100 and the NodeB 200, soft handoff between cells, and Hard handoff determination, transcoding and vocoding, GPS clock distribution, and operation and maintenance of the NodeB 200 are performed. In addition, the RNC 210 transmits subscriber information of the location-registered communication terminal 100 to the MSC 220. The RNC 210 transmits the call request signal transmitted from the communication terminal 100 through the NodeB 200 to the MSC 220, and, conversely, the RNC 210 transmits the call request signal transmitted from the MSC 220 to the NodeB ( It serves to deliver to the communication terminal 100 through the 200.

The MSC 220 performs basic and additional service processing, reception and outgoing call processing of a subscriber, location registration procedure and handoff procedure, and interworking with other networks. For example, the MSC 220 of the IS-95 / A / B / C system includes an Access Switching Subsystem (ASS) that performs distributed call processing, and an Interconnection Network Subsystem (INS) that performs centralized call processing. It includes a subsystem such as a Central Control Subsystem (CCS), which is in charge of centralizing operations and maintenance, and a Location Registration Subsystem (LRS), which performs storage and management of information on mobile subscribers. In addition, the MSC 220 for the third and fourth generation may include an Asynchronous Transfer Mode (ATM) switch. The ATM switch increases the transmission speed and the efficiency of line use by packet transmission of cells. When the location registration of the communication terminal 100 is performed through the NodeB 200 and the RNC 210, the MSC 220 temporarily stores subscriber information of the communication terminal 100 in the VLR 240 and then HLR (). Request a location registration of the communication terminal 100 to 230.

The HLR 230 receives location information of the communication terminal 100 from the VLR 240 and performs functions such as registration recognition, registration deletion, and location verification. In addition, the HLR 230 stores profile information of the communication terminal 100 waiting for a call. Here, the profile information refers to a mobile identification number (MIN), an electronic serial number (ESN) and / or subscribed mobile communication service information of the communication terminal 100.

The VLR 240 receives and stores the location information of the visited subscriber from which the location information registration is performed, from the MSC 220. When the communication terminal 100 performs location information registration, the VLR 240 temporarily stores subscriber information and notifies the HLR 230 to the terminal identification number of the communication terminal 100 and the terminal from the HLR 230. While taking over and managing a copy of the unique number and service information, and performs a function to utilize the location control, call processing, external operation processing of the communication terminal 100.

SGSN 250 may include a Gateway GPRS Support Node (GGSN). SGSN 250 is a mobile terminal for the GPRS (General Packet Radio Service) service, the management of the call / incoming and outgoing signal processing and session (Session) management, authentication and billing functions for handling the transmission and reception of packet data, etc. Support. It also has a routing process for packet data. Here, the GGSN is a serving node of an IP-based packet network that provides a high speed packet data service for GPRS. The GGSN performs session management and packet data routing functions for the packet data service and connects the wired / wireless communication network 130. GPRS is an asynchronous communication system that supports 384 Kbps data transmission speed, provides multimedia mail, and maximizes transmission line efficiency by packet data transmission.

The positioning server 140 may interwork with the wired / wireless communication network 130 and may additionally interwork with the LBSP 170. The positioning server 140, when there is a positioning instruction from the LBSP 170, requests positioning for the communication terminal 100 for handset based positioning or network based positioning, and GPS information as positioning information from the communication terminal 100. Receives some or all of the AP information and the base station information, and determines whether to use the location of the mobile AP 112 by using the received location information and the WLAN information provided by the WLAN server 150. In other words, the positioning server 140 may provide a positioning result by using only the fixed AP 111 when enough AP information about the fixed AP 111 is provided as the positioning information, but as the positioning information, the fixed AP ( When the AP information for 111 is not sufficient or only the AP information for the mobile AP 112 is provided, it is determined whether there is available time zone information to utilize the AP information for the mobile AP 112 for positioning. When the viewpoint is included in the available time zone, the AP information of the mobile AP 112 is utilized.

Table 1 may be useful for identifying available time zone information for the mobile AP 112 as WLAN information and usage pattern information stored in the secondary DB of the WLAN server 150. In Table 1, when looking at the MAC address (MAC addr) of the mobile AP 112, it can be seen that the same subscriber shows two or more behavior patterns. In this case, it is a clear pattern that subscribers move between work and home, and they are mainly in the company from 10 am to 20 am and at home from 24 am to 6 am. In addition, in Table 1, subscriber information (or MIN information) is for identifying the management entity of the mobile AP 112, for example, from the subscriber information who is carrying the mobile AP 112, such as an egg. It should be understood that the movement pattern of the mobile AP 112 can be considered when positioning.

Accordingly, the positioning server 140 searches for the DB 150a of the WLAN server 150 based on the AP information for the fixed AP 111 when sufficient AP information for the fixed AP 111 is provided as the positioning information. By providing the positioning result to the service requester, when the AP information for the fixed AP 111 is not sufficient or only the AP information for the mobile AP 112 is provided by utilizing the effective time zone information of the mobile AP (112) By searching the DB 150a of the WLAN server 150 based on the AP information on the mobile AP 112 and providing the positioning result, it is possible to provide more accurate information as the positioning result when the service subscriber requests a service such as a friend search. Could be. In other words, the mobile AP 112 preferably changes location information for the mobile AP 112 in order not to cause a positioning error because a change in location occurs, but on the contrary, the mobile AP 112 is mobile as in the embodiment of the present invention. By utilizing the effective time zone information of the AP 112, it is possible to obtain a more accurate positioning results than when using only the fixed AP (112).

In order to perform the above operation, the positioning server 140 may include, for example, a call processing unit 300 and a mobile AP positioning utilization determination unit 310, and the mobile AP positioning utilization determination unit 310 may store a memory. The unit 311 and the validity time determination unit 313 may be included. Here, the call processing unit 300 performs call processing in association with the wired / wireless communication network 130 and the LBSP 170. The memory unit 311 may receive and temporarily store the WLAN information stored in the DB 150a of the WLAN server 150 provided through the call processing unit 300. In addition, the memory unit 311 may store a comparison value for determining whether the AP information of the fixed AP 111 determined by the valid time determiner 313 is n or more.

The valid time determination unit 313 compares the AP information of the fixed AP 111 and the mobile AP 112 provided as the location information with the WLAN information stored in the memory unit 311 to determine the AP information for the fixed AP 111. Determine if n or more. For example, the validity time determination unit 313 compares the MAC addresses of the fixed AP 111 and the mobile AP 112 provided as the location information with the MAC addresses of the WLAN information to the fixed AP 111 and the mobile AP ( The AP information of 112 may be distinguished from each other, and the number of AP information for the fixed AP 111 may be compared with the comparison value of the memory unit 311 to determine whether there are n or more pieces.

If the number of AP information for the fixed AP 111 is less than n, the reliability of the corresponding AP 110, for example, the mobile AP 112, is utilized by utilizing radio environment information such as the NodeB 200 provided as positioning information. First, if the base station (NodeB) information provided as positioning information and the base station information of the WLAN information stored in the memory unit 311 coincide with each other, it is determined that the reliability has been verified, and then the mobile AP 112 whose reliability has been verified. It is determined whether there is a mobile AP 112 of a time zone that can be utilized for positioning. If the base station information does not coincide with each other, it will lead to a positioning failure. However, if there is a mobile AP 112 of a time zone that can be verified for reliability and available for positioning through the matching of the base station information, the AP for the corresponding mobile AP 112. The DB 150a of the WLAN server 150 is searched based on the information, and the positioning result is provided to the service requester.

The WLAN server 150 includes a DB 150a in which WLAN information about the AP 110 of FIG. 1 is stored. Here, the DB 150a may be divided into a primary DB and a secondary DB as shown in FIG. 4. The primary DB collects wireless LAN information such as locations of APs 110 installed in all regions using mobile vehicles, without distinguishing between fixed and mobile types, and matches them with grid cells classified by pCell ID. The secondary DB represents the DB arranged by processing the WLAN information of the primary DB and classifying by MAC address into a table form. As described above, the wireless LAN information of the AP 110 built in the primary DB and the secondary DB may be adjusted according to the timing of building the WLAN information. In addition, the WLAN server 150 receives the usage pattern information for each time zone of the AP 110 provided by the AP usage pattern analysis server 160 and stores the MAC pattern separately for each MAC address. As the DB 150a of the WLAN server 150 is constructed in this manner, the WLAN server 150 is fixed to the APs 110 stored in the secondary DB as WLAN information according to the request of the positioning server 140. Matching the grid cells based on the AP information of the AP 111 provides the corresponding information as a positioning result, or provides the positioning result based on the AP information of the mobile AP 112.

The AP usage pattern analysis server 160 manages time pattern usage pattern information of a user who uses a tethering service or carries an AP 110 (hereinafter referred to as A user). Here, tethering is a function that can utilize the communication terminal 100 as a modem, to connect an IT device such as a notebook to the communication terminal 110 to use the wireless Internet, the usage pattern information is a user's usage pattern As a kind of statistical data for, such statistical data can obtain valid data, for example, by tracking the use of user A's communication terminal 100. In other words, after analyzing the AP information for the same AP 110 from the positioning information provided by requesting the positioning of the user A's communication terminal 100, the user A calculated statistical data from 9 am to 6 pm on weekdays. If you work in the office of Gangnam until the city and live in Guro at night, you can see that the user A has a clear pattern of coming and going between the company and home. Of course, the user's specific valid data for each time slot may be calculated through a method of requesting positioning for user A at a predetermined time interval. The usage pattern information for each time zone calculated through this process is provided from the AP usage pattern analysis server 160 when the WLAN server 150 requests.

FIG. 5 is a diagram illustrating a positioning method of the positioning device shown in FIG. 1.

Referring to FIG. 5 together with FIGS. 1 and 3, first, the WLAN server 150 receives AP usage pattern information of the APs 110 from the AP usage pattern analysis server 160 and then performs a DB together with the WLAN information. In operation 150, it is stored in 150a. Here, the AP usage pattern information is data that can be used to know the usage pattern for the user possessing the AP 100, and includes information on the use place of the AP 110 and available time for each time zone. For example, the DB 150a of the WLAN server 150 processes wireless LAN information of the primary DB and the primary DB storing wireless LAN information acquired through a mobile vehicle for each grid cell and stores them separately by MAC address. Since the information may be divided into one secondary DB, the AP usage pattern information may be stored in the secondary DB together with the WLAN information.

Subsequently, the positioning server 140 requests the positioning to the communication terminal 100 according to the instruction from the LBSP 170 (S503).

Afterwards, the positioning server 140 receives the AP information provided by the communication terminal 100 through short-range communication with the AP 110 recognized in the vicinity as positioning information (S505). Here, the positioning information may further include some or all of the GPS information and the base station information.

In addition, the positioning server 140 requests WLAN information and AP usage pattern information for the APs 110 to the WLAN server 150 and then receives WLAN information and AP usage pattern information from the WLAN server 150 (S507). ). Since this process may be performed before receiving the above location information, the embodiment of the present invention will not be specifically limited to such a procedure.

The location server 140 compares the AP information provided as the location information with the WLAN information and the AP usage pattern information provided from the WLAN server 150 and analyzes whether there is availability for each time slot for the mobile AP 112 (S509). ). For example, the positioning server 140 may utilize valid time information of the mobile AP 112 when the provided positioning information does not have enough AP information on the fixed AP 111 or only includes AP information on the mobile AP 112. It would be desirable to analyze if it can.

Substantially, the positioning server 140 determines whether there is n or more AP information for the fixed AP 111 before analyzing whether there is valid time information of the mobile AP 112, and when less than n, the mobile AP ( In order to verify the reliability of the 112, a process of additionally comparing the base station information of the mobile AP 112 may be performed.

As a result, if the reliability of the mobile AP 112 is verified, for example, if the base station information is matched, the positioning server 140 provides the valid time information on the mobile AP 112 to the WLAN server 150 to provide the valid time information. The provision of the positioning result based on the request is made (S511).

Subsequently, the positioning server 140 receives the positioning result provided to the WLAN server 150 and provides the service requester (S513).

6 is a diagram illustrating a driving process of the positioning server illustrated in FIG. 1.

Referring to FIG. 6 together with FIGS. 1 and 3, the positioning server 140 receives positioning information provided when a positioning request of the communication terminal 100 is performed (S601). In this case, the positioning information may include AP information about the AP 110 performing short range communication with the communication terminal 100, and may further include GPS information and base station information.

After the positioning server 140 receives the positioning information, the WLAN server 150 requests the WLAN information and the AP usage pattern information to additionally receive the WLAN information and the AP usage pattern information to a separate memory unit 311. Can be stored.

This process may be substantially different depending on whether the analysis is performed by the positioning server 140 or the WLAN server 150 to utilize the valid time information of the mobile AP 112 included in the positioning information. In the embodiment of the positioning server 140 has been described taking as an example.

Thereafter, the positioning server 140 compares AP information provided as positioning information with WLAN information stored in the memory unit 311 to determine whether the number of AP information for the fixed AP 111 is n or more (S603).

If there are n or more, the positioning server 140 performs a positioning algorithm using the n or more AP information (S605). For example, when n is 3 and assuming that three AP information have different location information, the positioning algorithm may provide the positioning result to the service requester after performing the positioning algorithm using the triangulation technique. . Of course, the embodiment of the present invention has been described as an example of applying the triangulation technique to the positioning algorithm, but is not intended to be particularly limited thereto.

On the other hand, if less than n, the positioning server 140 compares the base station information for the mobile AP 112 with the base station information provided as the WLAN information, for example, to verify reliability of the mobile AP 112 for positioning. (S607).

If the two base station information does not coincide with each other, the positioning server 140 determines that the mobile AP 112 cannot be used for positioning and leads to positioning failure (S609). In other words, when the positioning server 140 provides the positioning result based on the AP information of the mobile AP 112 provided as the current positioning information, the positioning accuracy is very poor.

However, if there is a mobile AP 112 in which the two base station information coincide with each other, the positioning server 140 further determines whether time slot information of the mobile AP 112 can be utilized for positioning (S611).

As a result, if time zone information is useful, the positioning server 140 calculates the position by using the time zone information for positioning (S613).
