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

The mobile terminal 100 includes a short-range communication module, and acquires identification information on the short-range communication module of 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, 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 mobile terminal 100 includes a Bluetooth communication module as a near field communication module.

In addition, the mobile terminal 100 may obtain a MAC address (MACA) of the near field communication module installed in the other terminal 110 capable of communicating using the near field 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 may serve as a server for providing location and status information for another terminal 110, and may be linked with a server such as a messenger service providing server and a friend search service providing server. In this case, the service server 200 stores identification information on the terminal of the service subscriber, receives identification information on the short-range communication module of the other terminal 110 from the mobile terminal 100, and moves the matching subscriber list. Transmission to the 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, and the Bluetooth of the short-range communication module of the other terminal 110 received from the mobile terminal 100. The MAC address is compared with the stored service subscriber's MAC address to transmit a subscriber list of matching MAC addresses to the mobile terminal 100. Therefore, the subscriber list transmitted by the service server 200 to the mobile terminal 100 becomes a list of users who have subscribed to the service among users of the other terminal 110 in the vicinity of the mobile terminal 100.

The location server 210 locates the location of the service subscriber's terminal. The positioning server 210 is a server for providing a location based service (LBS) to the mobile terminal 100 and may store the location information of the terminal of the service subscriber.

The location positioning method for providing a location-based service to a mobile terminal includes a network-based method of 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 mobile terminal; There are a handset based method using a GPS (Global Positioning System) receiver installed in a mobile terminal, and a hybrid method in which these 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), a protocol for positioning A-GPS in OMA SUPL (Secure User Plane Location) interface and OMA SUPL (Mobile Positioning Center) within mobile terminal with GPS receiver and GSM network The positioning of the mobile terminal is performed by sending and receiving a message through the GSM A-GPS protocol (embedded Resource Location Protocol). The positioning is very accurate because the positioning is performed by receiving 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 mobile 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 in 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).

The OTD means a difference in arrival time of a signal arriving from two base stations to a mobile terminal and can be obtained by measuring a UE Rx-Tx Time Difference Type 2 parameter in a GSM-based mobile 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 mobile terminal and the LMU to the positioning server by using a promise protocol (IS-801, RRLP, RRC, etc.) between the mobile terminal and the server. The positioning server performs the positioning function of the corresponding mobile terminal by using the measurement data (PPM, OTD, RTD, etc.) of the mobile terminal. 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 mobile 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.

In the method using the distance information, first, by measuring each distance from the three or more APs that know the location to the mobile terminal to know the location, and performing 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 mobile terminal and the AP is measured (predicted) using methods such as Time of Arrival (ToA), Time difference of Arrival (TdoA), and Received Signal Strength (RSS).

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 by using whether the mobile 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 mobile terminal 100 based on the subscriber list transmitted by the service server 200 to the mobile terminal 100. If selected, the location and status information of the terminal corresponding to the selected service subscriber may be transmitted to the mobile terminal 100.

Or, if the location server 210 searches the identification information of the matching subscriber terminal based on the identification information of the short-range communication module of the other terminal 110 received from the mobile terminal 100, the service server 200, service The location and status information of the terminal of the service subscriber retrieved by the server 200 may be transmitted to the mobile 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.

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 the Bluetooth communication module is provided in the mobile terminal 100, the Bluetooth communication module may receive the MAC address of the communicable Bluetooth communication module provided in the other 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 of the short range communication unit 101 is in an OFF state, the on / off control unit 102 performs a short range communication unit 101 to inquire position and state information of another terminal 110 according to the present invention. The power supply can be controlled to be switched to an ON state, and a user can recognize the text or image on the screen of the mobile terminal 100 as necessary.

If the identification information of the subscriber stored in the server 200 is matched (that is, if only the user of another terminal corresponding to A and B subscribes to the same service as the user of the mobile terminal 100), the user interface unit 104 ) Receives the location and status information about the other terminal 110 corresponding to A and B from the service server 200 and displays it on the screen of the mobile terminal 100.

The list receiving unit 105 may receive a list of service subscribers from the service server 200 in response to the location and status information about the other terminal 110 requested by the requesting unit 103. For example, when the identification information of the short-range communication module of each other terminal 110 transmitted by the requesting unit 103 is A, B, C, and D as described above, only A and B are serviced. If the identification information of the subscriber stored in the server 200 is matched, the list receiving unit 105 may receive a list of subscribers corresponding to A and B by requesting the list of subscribers corresponding to the request of the 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 location and status information of the 110 is received and displayed on the screen of the mobile terminal 100.
