BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a location and status information providing system using local area communication according to an embodiment of the present invention; FIG. Referring to the drawings, a location and status information providing system using local communication according to an embodiment of the present invention may be configured of a mobile terminal 100, a service server 120, and a positioning server 130.

The mobile terminal 100 includes a local area communication module and obtains identification information of the local area communication module of at least one other terminal 110 by using the local area communication module, To the service server 200 through the network 120 or the mobile communication network 130. [0064] 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. Hereinafter, it is assumed that the mobile terminal 100 includes a Bluetooth communication module as a short-range communication module.

Also, the mobile terminal 100 may acquire a MACA (Media Access Control Address) of a short distance communication module installed in the other terminal 110 capable of communicating using the short distance communication module. MACA (Media Access Control Address) refers to the physical address of Ethernet. The MAC address is written in ROM (Read Only Memory) of the Ethernet card, and the address size is generally 48 bits. When the Institute of Electrical and Electronics Engineers (IEEE) allocates the first 24 bits of the vendor, . In the monitor initial screen for monitoring the network operation status, the name of each machine is previously assigned to a network interface card (NiC) and is indicated by a MAC address. Is written in a ROM on a LAN connection of a personal computer or a local area network (LAN) device, and a transmission destination and an address are designated and used in front of the MAC layer data frame (header).

The network 120 is used as a broad concept including a wireless Internet network such as WiBro (Wireless Broadband) and LTE (Long Term Evolution) as well as a wired network such as a VAN (Value Added Network). 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 server for providing location and status information about the other terminal 110, and may be interworked 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 the identification information on the local communication module of the other terminal 110 from the mobile terminal 100, and moves the list of matching subscribers To the terminal (100). That is, the service server 200 stores the MAC address of the Bluetooth communication module, which is a local communication module installed in the terminal of the subscriber subscribed to the service, and stores the MAC address of the Bluetooth communication module of the other terminal 110, Compares the MAC address with the MAC address of the stored service subscriber and transmits the matching subscriber list to the mobile terminal 100. Accordingly, the list of subscribers transmitted to the mobile terminal 100 by the service server 200 is a list of users who subscribe to the service among the users of the other terminal 110 located in the vicinity of the mobile terminal 100. [

The positioning server 210 locates the position of the service subscriber with respect to the terminal. The positioning server 210 is a server for providing a location based service (LBS) to the mobile terminal 100, and can store location information of the service subscriber with respect to the terminal.

In order to measure the position of a mobile terminal, a location based positioning method for providing a location-based service to the mobile terminal includes a network-based method of confirming a position using a radio wave environment, which is a cell radius of a base station of a mobile communication network, A handset based method using a GPS (Global Positioning System) receiver installed in a mobile terminal, and a hybrid method of combining these two methods.

The A-GPS system is a handset-based system, and is a system that uses a GSM (Global System for Mobile Communication) -based network and a Code Devision Multiple Access (CDMA) wireless access system using Time Division Multiple Access (TDMA) It is available in all -95 based network technologies. In the GSM wireless access scheme, a secure user plane location (OMA) SUPL (SUPL) interface and a protocol for positioning A-GPS in the OMA SUPL between a mobile terminal with a GPS receiver and a SPC (Supl Positioning Center) (GSM A-GPS protocol with a built-in Resource Location Protocol), which receives four or more satellite signals from GPS satellites and performs positional positioning. The A-GPS system includes an SPC (SUPL Positioning Center) for calculating a position by receiving a satellite signal received from a mobile terminal and a location information center (SLC: SUPL) for linking the calculation based on the base station information in the GSM mobile communication network, Location Center).

E-OTD (Enhanced Observed Time Difference) is standardized through LCS Release 98 and 99 in the GSM standard Committee of the European TDMA-based GSM using the TDMA wireless access standard as a typical network-based positioning method. The position of the signal received by the base station is determined by calculating the difference between the relative arrival time and the distance. The E-OTD method is a method that is used to calculate the network-based positioning by combining time difference concepts such as OTD (Observed Time Difference), RTD (Relative Time Difference), and GTD (geometric time difference).

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 UE Rx-Tx Time Difference Type 2 Parameter in a GSM-based mobile terminal.

The RTD is a parameter that can determine the start time difference of signals transmitted from two base stations and can be measured only by mounting a LMU (Location Measurement Unit), which is a separate measurement device, in the base station. Therefore, in order to obtain "GTD = OTD - RTD" which is a key parameter for calculating the position of the network system recommended in the GSM standard, it is necessary to obtain not only the OTD but also the RTD to perform the network position calculation of the E-OTD method.

The network-based location location technology transmits data (PPM, OTD, RTD, etc.) measured by the mobile terminal and the LMU to the positioning server by the promised protocol (IS-801, RRLP, RRC, etc.) between the mobile terminal and the server, The positioning server performs the positioning function of the mobile terminal using the measurement data (PPM, OTD, RTD, etc.) of the mobile terminal. The positioning server carries out a network positioning (a method of positioning the location of the terminal requested by the server at the server end, excluding the position measurement method using the GPS satellite), and transmits the result to a target (SLC, CP ), A mobile terminal requesting a service, etc.).

This network-based location positioning technique uses a triangulation method that uses the coordinates and distances of three or more access points (APs) that generally know the location, and a method of using the measured (predicted) Information is not used.

In the method of using the distance information, the distances from the three or more APs that know the location to the mobile terminal to know the location are measured, and then the triangulation method using the measured distance and the location information of the APs is performed, Lt; / RTI > At this time, 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 RSS (Received Signal Strength).

ToA is a method of measuring the distance by using the time when a signal that knows the propagation speed travels between APs. TdoA is a method of measuring the distance using the time difference between the signals arriving at two APs by simultaneously transmitting two signals with different speeds. These two methods result in a more accurate measurement result as the lower signal speed and the absence of obstacles between APs.

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

There are Centroid method and APIT (Approximate Point In Triangulation) method as location recognition methods that do not use distance information. These methods are based on the recognition that methods using distance information in a multi-hop sensor network can spread errors to the network.

The centroid method is a method of estimating (measuring) its own position by comparing strengths of signals received from neighboring APs when each of the regularly arranged APs transmits their position information to the neighboring APs. The Centroid method can obtain more accurate measurement results as the APs are arranged regularly, the more APs capable of communicating with themselves, and the same RF propagation environment are maintained. The APIT method predicts a location using whether a mobile terminal to measure a location exists within a triangle formed by each AP. The positioning server 210 may provide location-based services in various manners as described above.

The positioning server 210 is interlocked with the service server 200 and transmits at least one service subscriber by the mobile terminal 100 based on the subscriber list transmitted to the mobile terminal 100 by the service server 200 The mobile terminal 100 can transmit the location and status information of the terminal corresponding to the selected service subscriber to the mobile terminal 100.

Alternatively, when the service server 200 searches the identification information of the subscriber terminal matching the base station based on the identification information of the local communication module of the other terminal 110 received from the mobile terminal 100, And may transmit the location and status information of the terminal of the service subscriber searched by the server 200 to the mobile terminal 100. 1, the service server 200 and the positioning server 210 are independently configured. However, the positioning server 210 may be integrally implemented in the service server 200.

The requesting unit 103 transmits the obtained identification information of the local communication module of the other terminal 110 to the service server 200 so as to inquire whether the other terminal 110 is subscribed to the service, 110). ≪ / RTI > For example, when each of the identification information obtained from the neighboring other terminals 110 is A, B, C, and D, the requesting unit 103 transmits the identification information A, B, C, and D to the service server 200 to inquire whether or not to join the service, and request location and status information about the other terminal 110 as a service subscriber.

The user interface unit 104 receives the location and status information of the other terminal 110 from the service server 200 and displays the received location and status information on the screen of the mobile terminal 100.

[

The list receiving unit 105 can receive a list of service subscribers from the service server 200 in response to the location and status information of the other terminal 110 requested by the request unit 103. [ For example, when the identification information for the local communication module of each of the other terminals 110 transmitted by the request unit 103 is A, B, C, and D, The list receiving unit 105 may request the list of subscribers corresponding to the request of the requesting unit 103 and receive the list of subscribers corresponding to A and B. If the subscriber list matches the identification information of the subscriber stored in the server 200,

The subscriber selection unit 106 can 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 subscriber list received by the list receiving unit 105 is a subscriber corresponding to A and B, the subscriber selecting unit 106 can 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, and accordingly, the user interface unit 104 transmits the subscriber selection signal selected by the subscriber selection unit 106 to the other terminal And displays the position and status information of the mobile terminal 100 on the screen of the mobile terminal 100.
