1 is a view schematically showing a log information providing / querying system using short-range communication according to an embodiment of the present invention. Referring to the drawings, the log information providing / querying system using the short-range communication according to an embodiment of the present invention may include a customer terminal 100, a service server 120 and the positioning server 130.

The customer terminal 100 includes a short-range communication module, and acquires identification information of the short-range communication module provided in at least one other terminal 110 in the vicinity by using the short-range communication module, and obtains the obtained other terminal 110 The identification information of the short range communication module may be transmitted to the service server 200 through the network 120 or the mobile communication network 130. Here, although the customer terminal 100 is shown as being implemented as a wireless terminal, the customer terminal 100 may be implemented as a wired terminal such as a computer. That is, the customer terminal 100 may be a wired terminal provided in a specific area, and may obtain identification information of the wireless terminal 110 of another person moving in the corresponding area by using a short range communication module. In addition, the short range communication module may be a Bluetooth communication module, a UWB (Ultra Wide Band) communication module, a Zigbee communication module, or the like. In the following description, it is assumed that the customer terminal 100 includes a Bluetooth communication module as a short range communication module.

The customer terminal 100 may obtain a MAC address (MACA) of the short range communication module installed in the other terminal 110 capable of communicating using the short range communication module. The MAC address (MACA) is a physical address of Ethernet. The MAC address is written to the Ethernet card's Read Only Memory (ROM), which is typically 48 bits in size. When the Institute of Electrical and Electronics Engineers (IEEE) assigns a first-half 24-bit vendor, the vendor assigns a detailed allocation to the second-half 24-bit. Do it. In the initial monitor screen for monitoring the network operation status, each machine name is previously assigned to a network interface card (NiC) and displayed as a MAC address. Normally, a personal computer or a local area network (LAN) device writes in a ROM on a LAN connection port, and a sender and an address are designated and used in front of a MAC layer data frame.

The network 120 is used in a broad concept, including a wired network such as a value added network (VAN) as well as a wireless Internet network such as a wireless broadband (WiBro) and a long term evolution (LTE). In addition, the mobile communication network 130 includes a code division multiple access (CDMA) network, a wideband CDMA (WCDMA) network, and the like.

The service server 200 is a service for providing log information for another terminal 110, and stores identification information of a terminal of a service subscriber, and the subscriber terminal connects the network 120 or the mobile communication network 130. When connected via the terminal, log information including access point and location information of the subscriber station can be recorded. In addition, the service server 200 may receive identification information on the short-range communication module of the other terminal 110 from the customer terminal 100 and transmit a list of matching subscribers to the customer terminal 100. That is, the service server 200 stores the MAC address of the Bluetooth communication module, which is a short-range communication module installed in the terminal of the subscriber subscribed to the service, for the short-range communication module of the other terminal 110 received from the customer terminal 100. By comparing the Bluetooth MAC address and the stored service subscriber's MAC address, the subscriber list of matching MAC addresses may be transmitted to the customer terminal 100. In this case, the subscriber list transmitted by the service server 200 to the customer terminal 100 is a list of users who have subscribed to the service among the users of the other terminal 110 in the vicinity of the customer terminal 100.

In addition, the service server 200 is interlocked with the positioning server 210 for the subscriber terminal that matches the identification information of the short-range communication module of the other terminal 100 received from the customer terminal 100 to determine the current position The log information may be updated based on the result of positioning by the positioning server 210 only when the access point included in the log information of the subscriber terminal and the current position where the location information is positioned are different.

The location server 210 locates the location of the service subscriber's terminal. The positioning server 210 is a server that provides a location based service (LBS) to the customer terminal 100 and may store a location value of the terminal of the service subscriber.

The location positioning method for providing location-based services to a customer terminal includes a network-based method for identifying a location in software using a radio environment, which is a cell radius of a base station of a mobile communication network, to measure the location of the customer terminal. There is a handset based method using a global positioning system (GPS) receiver installed in a customer terminal, and a hybrid method in which the two methods are mixed.

The A-GPS method is a handset-based method, and an IS using European-based Global System for Mobile Communication (GSM) -based network using a Time Devision Multiple Access (TDMA) radio access method and a Code Devision Multiple Access (CDMA) radio access method. It can be used in both -95 based network technology. In the GSM wireless access method, SUPL POS (RRLP (Radio, RLPLP), a protocol for A-GPS positioning in OMA SUPL and OMA Secure User Plane Location (OPL) interface between customer terminal with GPS receiver and SPC (Supl Positioning Center) in GSM network The positioning of the customer terminal is performed by sending and receiving messages through the GSM A-GPS protocol (embedded Resource Location Protocol). The positioning is very accurate because it receives and locates four or more satellite signals from the GPS satellites. The A-GPS system is a SPL (SUPL Positioning Center) that calculates the position by receiving satellite signals received from the customer's terminal and a location information center (SLC: SUPL) that links calculations based on base station information in the GSM mobile communication network to other systems. Location Center).

E-OTD (Enhanced Observed Time Difference) is a representative network-based positioning method, standardized through LCS Release 98 and 99 at the GSM standard committee of TDMA-based GSM system in Europe using TDMA radio access standard. The position received is determined by calculating a difference between a relative arrival time and a distance received from the base station. The E-OTD method combines time difference concepts such as Observed Time Difference (OTD), Relative Time Difference (RTD), and Geometric Time Difference (GTD).

OTD means the difference in the arrival time of the signal arriving from the two base stations to the customer terminal, it can be obtained by measuring the UE Rx-Tx Time Difference Type 2 parameter in the GSM-based customer terminal.

RTD is a parameter that can be used to obtain the start time difference between signals transmitted from two base stations. Measurement is possible only when the base station is equipped with a separate measurement unit (LMU). Therefore, in order to obtain "GTD = OTD-RTD" which is a key parameter for the network location calculation recommended in the GSM standard, the E-OTD type network location calculation can be performed only by obtaining RTD as well as OTD.

The network-based positioning technology delivers data (PPM, OTD, RTD, etc.) measured by the customer terminal and the LMU to the positioning server by a promised protocol (IS-801, RRLP, RRC, etc.) between the customer terminal and the server. Using the measurement data (PPM, OTD, RTD, etc.) of the customer terminal performs the positioning function of the customer terminal in the positioning server. The positioning server performs network location positioning (a method of positioning a location of a terminal requested for positioning at a server end except for a positioning method using GPS satellites), and transmits the result to a target requesting a positioning service (SLC, CP (Contents Provider). ), The customer terminal requesting the service, etc.).

This network-based positioning technique generally uses triangulation using coordinates and distances of three or more access points (APs) that know the location, and uses largely measured (predicted) distance information and distance. Classified in a way that does not use information.

The method of using the distance information first measures each distance from three or more APs that know the location to the customer terminal that wants to know the location, and then performs a triangulation method using the measured distance and the location information of the AP. Obtain the position of. In this case, the distance between the customer terminal and the AP is measured (predicted) using methods such as Time of Arrival (ToA), Time difference of Arrival (TdoA), Received Signal Strength (RSS), and the like.

ToA is a method of measuring distance by using the time traveled between APs having known propagation speed. TdoA transmits two signals with different speeds at the same time and measures the distance by using the time difference between two APs. In these two methods, the lower the speed and the more obstacles exist between the APs, the more accurate the measurement result is calculated.

RSS is a method of measuring the distance by using the strength of the received signal reaching the node. The RF signal used by RSS has better diffraction characteristics than ultrasonic waves or sound waves, so it is easy to secure visibility (LoS) and does not require additional hardware.

Location recognition methods that do not use distance information include a centroid method and an APIT (Approximate Point In Triangulation) method. These methods begin with the recognition that methods using distance information in a multi-hop sensor network can spread errors in the network.

The centroid method is a method in which each AP arranged regularly transmits its location information to the neighboring AP to predict (measure) its position by comparing the strength of signals received from previous APs. In the centroid method, as the APs are regularly arranged, as the number of APs that can communicate with them, and as the RF propagation environment remains the same, more accurate measurement results can be calculated. The APIT method predicts the location using whether or not the customer terminal to measure the location exists in a triangle formed by each AP. The location server 210 may provide location based services in various ways as described above.

In addition, the positioning server 210 interlocks with the service server 200, and at least one service subscriber is determined by the customer terminal 100 based on the subscriber list transmitted by the service server 200 to the customer terminal 100. If selected, the log information of the terminal corresponding to the selected service subscriber may be transmitted to the customer terminal 100.

Or, if the location server 210 searches the identification information of the matching subscriber terminal based on the identification information on the short-range communication module of the other terminal 110 received from the customer terminal 100, the service server 200, The log information of the terminal of the service subscriber retrieved by the server 200 may be transmitted to the customer terminal 100. In FIG. 1, the service server 200 and the positioning server 210 are described as being configured independently, but the positioning server 210 may be integrally implemented in the service server 200.

The short range communication unit 101 refers to the above short range communication module, and may be implemented as a Bluetooth communication module, a UWB communication module, a Zigbee communication module, or the like. The short range communication unit 101 obtains identification information of a short range communication module provided in at least one other terminal 110 around the current location of the customer terminal 100. In this case, the short-range communication unit 101 may obtain the MAC address of the short-range communication module that can communicate from other terminals around the neighbor 110 as identification information. For example, when a Bluetooth communication module is provided in the customer terminal 100, the Bluetooth communication module may receive the MAC address of the communicable Bluetooth communication module provided in the neighboring terminal 110 as identification information.

The on / off control unit 102 controls the on / off of the power supply of the local area communication unit 101. That is, when the power supply of the near field communication unit 101 is in an OFF state, the on / off control unit 102 supplies power to the near field communication unit 101 in order to inquire log information of another terminal 110 according to the present invention. Can be controlled to be switched to an ON state, and if necessary, a user may recognize the text or image on the screen of the customer terminal 100.

The update request unit 103 transmits the acquired identification information on the short-range communication module of the other terminal 110 to the service server 200 and requests log information on the other terminal 110. For example, if each of the identification information obtained from the neighboring communication unit 101 from the plurality of neighboring terminals 110 is A, B, C, and D, the requesting unit 103 may identify each identification information A, The B, C and D may be transmitted to the service server 200 to request update of log information for each corresponding third party terminal 110.

The user interface 104 receives log information of another terminal 110 from the service server 200 and displays the log information on the screen of the customer terminal 100. For example, when the identification information of the short-range communication module of each other terminal 110 transmitted by the update request unit 103 is A, B, C and D as described above, only A and B are among them. If the subscriber's identification information stored in the service server 200 is matched (that is, only the user of another terminal corresponding to A and B has subscribed to the same service as the user of the customer terminal 100), the user interface unit ( 104 receives log information of another terminal 110 corresponding to A and B from the service server 200 and displays the log information on the screen of the customer terminal 100.

The list receiving unit 105 may receive a list of service subscribers from the service server 200 in response to the identification information of the short-range communication module of the other terminal 110 requested to be updated by the update requesting unit 103. For example, when the identification information of the short-range communication module of each other terminal 110 transmitted by the update request unit 103 is A, B, C and D as described above, only A and B are among them. If the identification information of the subscriber stored in the service server 200 is matched, the list receiving unit 105 may receive the subscriber list corresponding to A and B in response to the request of the update requesting unit 103.

The subscriber selection unit 106 may select at least one service subscriber from the list of service subscribers received from the service server 200. For example, as described above, if the list of subscribers received by the list receiving unit 105 is a subscriber corresponding to A and B, the subscriber selecting unit 106 may select one or all of the subscribers. In this case, the subscriber selection signal selected by the subscriber selection unit 106 is transmitted to the service server 200, so that the user interface unit 104 corresponds to another terminal corresponding to the service subscriber selected by the subscriber selection unit 106. The log information of the 110 may be received and displayed on the screen of the customer terminal 100.
