Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a location based service, and more particularly to an automatic position registering method in a mobile phone for minimizing a load of a server related to position information by enabling the position information to be transmitted to LBS (Location Based Service) server if a given conditions are satisfied after obtaining the position information by automatically operating a program in a mobile phone in order to obtain the position information of the mobile phone for the location based service.  
       BACKGROUND OF THE INVENTION  
       [0002]     For the conventional LBS (Location Based Service), generally the system of searching location of a certain mobile terminal by the LBS server acquiring location information from the mobile phone by the order of the LBS server has been used prevalently. In this event, whenever the location information is needed, a request message is transmitted from the LBS (Location Based Service) server to a certain mobile phone, and the location information is transmitted from the mobile phone to the LBS (Location Based Service) server. Thus, whenever a location request message is transmitted, a certain amount of network resource is needed. Hereinafter, the position registering method of a mobile phone according to the conventional technology will be explained by referring to  FIGS. 1 and 2 .  
         [0003]      FIG. 1  is a diagram showing the position registering system of a mobile phone according to the conventional art.  FIG. 2  is a call flow chart for explaining the registering method of a mobile phone according to the conventional art.  
         [0004]     As shown in the figures, reference number  10  represents a mobile phone; reference number  300  represents a location information providing system; and reference number  400  represents an LBS server. In the position registering system ( 100 ), reference number  110  represents a base transceiver station (BTS); reference number  120  represents a base station controller (BSC); reference number  130  represents a mobile switching center (MSC); reference number  140  represents an interworking facility (IWF); reference number  150  represents a signal transfer point (STP); and reference number  160  represents a home location register (HLR) Also, in the location information providing system ( 300 ), reference number  310  represents a position determination entity (PDE), and reference number  320  represents a mobile positioning center (MPC).  
         [0005]     The position registering system ( 100 ) is coupled to the position determination entity ( 310 ) of the location information providing system ( 300 ) and to the mobile positioning center ( 320 ) through the signal transfer point ( 150 ).  
         [0006]     The LBS server ( 400 ) provides location information service according to the request of a mobile phone user. Preferably, it is coupled to the mobile positioning center ( 320 ) of the location information providing system ( 300 ) by TCP/IP.  
         [0007]     The operating process of the position registering system of a mobile phone according to the conventional art, which has been constituted as described above, will be explained by referring to  FIG. 2 .  
         [0008]     First, the LBS server ( 400 ) requests the mobile positioning center ( 320 ) to provide a location service (S 110 ). Then, the mobile positioning center ( 320 ) sends an SMSREQ request message to the home location register ( 160 ) based on the MIN (Mobile Identification Number) of the mobile terminal which requested to provide a service (S 120 ). Herein, SMSNOTIND among the parameters of the SMSREQ messages is sent to 2, thereby preventing SMS pending.  
         [0009]     Thereafter, the home location register ( 160 ) sends an SMSREQ return result message to the mobile positioning center ( 320 ) (S 130 ). Then, the mobile positioning center ( 320 ) analyses SMSADDR comprised in the received SMSREQ return result message, and checks whether or not the incoming switching system enables the GPS based location service function. Herein, the mobile positioning center ( 320 ) sends GPOSREQ request message to the position determination entity ( 310 ) based on the result of the judgment of the incoming switching system concerning whether or not to provide the GPS based location service (S 140 ). The parameters, which are sent together with the GPOSREQ message, comprise MOBINFO, POSREQTYPE and MPCAP.  
         [0010]     Subsequently, the position determination entity ( 310 ) acquires the location information of a mobile terminal for which the location based service has been requested based on the IS-801-1 standard (S 150 ˜S 230 ) The location information received by the position determination entity ( 310 ) is sent to the mobile positioning center ( 320 ) through the GPOSREQ message. The parameters of the GPOSREQ message comprise POSINFO and POSRESULT.  
         [0011]     Then, the mobile positioning center ( 320 ) sends the location result to the LBS server ( 400 ) (S 250 ). Meanwhile, after the position determination entity ( 310 ) ends a message to the mobile positioning center ( 320 ) Lke the above, it sends an SMDPP message to the mobile qitching center (MSC) in order to release resources seated therein (S 260 ˜S 290 ).  
         [0012]     The mobile positioning center ( 320 ) functions as a gateteway between the mobile communication switching network and the LBS server ( 400 ). According to the location information request of the LBS server ( 400 ), it requests the mobile phone ( 10 ) to provide location information, and then if a location value is received from the mobile phone ( 10 ), it converts the value to real place name information and sends it to the LBS server ( 400 ). If the location information is sent to LBS server ( 400 ) through the mobile positioning center ( 320 ), the LBS server ( 400 ) helps it to be utilized in supplying various location based services.  
         [0013]     The above example concerns a GPS based location checking method. However, in the conventional location based service, whenever there is a necessity, the LBS server (the server handling location management) {circle around (1)} requests a terminal to register location, demands the terminal to calculate the location information, and receives a location value therefrom, or {circle around (2)} receives the location of the terminal measured by a base transceiver station (or a system which functions similarly thereto and a system apparatus handling mobile communication) or by a server system by using the location checking method based on the base transceiver station, the above GPS based location check, or ETDOA location checking system.  
         [0014]     Thus, for the above methods, the location checking request must be made from the LBS server to a terminal for all the location based services. For the purpose, communication between another apparatus of a mobile communication network (e.g., a system for checking location by a base transceiver station, GPS or ETDOA, etc.) and a terminal and continuous upload of location data are required.  
         [0015]     At this time, according to the request of the LBS server every time, the location is checked by the communication between the location checking system (e.g., HLR/MSC, MPC/PDE or a similar apparatus handling location measurement and the like) and a terminal. The terminal sends the measured value to the LBS server directly or through the location checking system.  
         [0016]     For the location check, every time, a number of apparatuses are required for the connection and communication with a terminal. Thereby, when there are a lot of requests for location check, considerable load is caused for both the terminal and the location checking system. Thus, expensive location system apparatus needs to be further established. Also, as well as the mobile communication network, it may effect associated services.  
         [0017]     Currently, in the domestic location checking system, the location check is divided into Cell-ID based location check and AGPS based location check and requests an assigned server to provide services by using the location check result. This method has a problem that when Cell-ID request is made from the LBS server to nearly all of the location based services, in case of HLR (including the apparatus playing a similar role as the home location register in GSM and WCDMA) and AGPS, the location information is requested to PDE, therefore the load of wireless network requiring location registration and LBS server including CDMA network (including MSC, BSC, BTS as well as HLR, PDE), GSM network or WCDMA network gets increased (When GSM, WCDMA system or another location checking method, e.g., ETDOA and the like, is used, the fundamental function is similar in proceeding with the location check in spite of slight differences in the system terms).  
         [0018]     Particularly, in case of a Cell-ID based system, it employs the page request method. If there are excessive page requests, it may influence on a voice telephone call by network occupation.  
         [0019]     Meanwhile, in case of AGPS, location is measured by using IS-801-1 protocol between PDE and a terminal. However, when the requests increase, expensive PDE devices are required to be additionally established, which increases the development costs and hinders service development. Further, when periodic location confirmation requests are required, overload may occur in HLR, MSC (Cell-ID based system), PDE and MPC (AGPS based system). Accordingly, there was a problem that the number of users is limited.  
       SUMMARY OF THE INVENTION  
       [0020]     Therefore, the present invention has been conceived in order to resolve the aforesaid problems in the prior art.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0026]     Hereinafter, the preferred embodiments of the present invention will be further explained by referring to the drawings attached hereto.  
         [0027]     As illustrated in the drawings, the automatic position registering method of a mobile phone comprises that an LBS (Location Based Service) server ( 20 ) requests a location information managing application (not shown) installed in a mobile phone ( 10 ) to operate (S 10 ); said location information managing application operates according to said request, and said location information managing application is connected with said LBS server ( 20 ) (S 20 ); the location information management conditions are transmitted from said LBS server ( 20 ) to said mobile phone ( 10 ) (S 30 ); said location information managing application, which has received said conditions, checks whether or not to acquire and upload location information according to said conditions (S 40 ); and the location information is transmitted to said LBS server ( 20 ) (S 50 ).  
         [0028]     The wireless Internet protocol can be applied to the mobile phone ( 10 ). Also, through the transmission network, which can provide IP protocol according to WAP service, Call Back URL and WAP push, and the IP Backbone network, the mobile phone ( 10 ) can communicate with the LBS (Location Based Service) server ( 20 ).  
         [0029]     The automatic position registering method configured as the above according to the present invention will be explained by referring to  FIG. 3  in the below.  
         [0030]      FIG. 3  is a diagram for explaining the automatic position registering method according to the present invention.  
         [0031]     First, if the LBS server ( 20 ) request the location information application (not shown) installed in the mobile phone ( 10 ) (S 10 ) to operate, the mobile phone ( 10 ) operates the location information managing application. Hence, the location information managing application is connected to the LBS server ( 20 ) (S 20 ). At this time, the LBS server ( 20 ) transmits the location information acquisition and transmission conditions to the mobile phone ( 10 ) (S 30 ). In other words, the LBS server ( 20 ) does not request the mobile phone ( 10 ) to provide real time location information, but simply transmits the conditions.  
         [0032]     The location information acquisition and transmission conditions between the LBS server ( 20 ) and the mobile phone ( 10 ) are transmitted by using SMS, or are transmitted from the LBS server ( 20 ) to the mobile phone ( 10 ) after TCP/IP connection, HTTP connection or SOAP connection from the mobile phone ( 10 ) to the LBS server ( 20 ).  
         [0033]     The location information acquisition and transmission conditions are divided into time conditions (which means transmission of location information within a given time) and geographical conditions. The time conditions includes location information acquisition and transmission start time, their periods and their termination time. Meanwhile, the geographical conditions includes a management area of a certain switching system, a management area of a certain plurality of base transceiver station groups, a management area of a certain base transceiver station, a center, coordinates and a radius of a certain base station or a certain address information.  
         [0034]     In addition, the geographical conditions may be administrative appellations such as “Gu (e.g., Gangnam-Gu, Jongno-Gu, etc.)” or “Dong (e.g., Seorin-Dong, Pil-Dong, etc.)” among certain address information. Also, it may be an administrative district code and an administrative radius of certain address information.  
         [0035]     The location information acquisition and transmission conditions are transmitted to the LBS server ( 20 ) after the location information managing application built in the mobile phone ( 10 ) calculates location information on the basis of the conditions.  
         [0036]     Thereafter, the location information managing application, which has received the above conditions, determines whether or not to acquire and upload location information according to the above conditions (S 40 ). Herein, while the location information managing application of the mobile phone ( 10 ) is measuring the location of the terminal periodically irrelevant to the location information management conditions of the LBS server ( 20 ), it checks whether or not to acquire and upload the location information according to the above conditions in case that it receives the location information management conditions from the LBS server ( 20 ).  
         [0037]     As stated above, the location information acquisition of the location information managing application can be performed independently rather than through communication with a certain server for location measurement, but the location may be still acquired through the communication with a given location measurement server after being performed at a terminal.  
         [0038]     In addition, the accuracy of the location information acquired by the location information managing application is evaluated based on an area managed by a certain switching system, an area managed by a single base station, a group of areas managed by a plurality of base stations, and coordinates which are obtained from the GPS receiver installed in the mobile phone ( 10 ). Additionally, the accuracy of the location information acquired by the location information managing application can be computed based on the area or the spot measured and acquired by the mobile phone ( 10 ).  
         [0039]     Thereafter, the location information managing application of the mobile phone ( 10 ) transmits location information, which is periodically measured, to the LBS server ( 20 ) only when it meets the location information management conditions (S 50 ). Herein, the location information managing application works in the background state, i.e., when the terminal screen is inactive or when the user does not recognize.  
         [0040]     However, the location information may not be transmitted to the LBS server ( 20 ). Instead, it can be simply used in the location information managing application of the mobile phone ( 10 ).  
         [0041]     The location information managing application stores the above acquired location information in a given database. It compares the location information in the past certain spot with the current location information, and transmits the location gap to the LBS server ( 20 ).  
         [0042]     Finally, the above location acquisition and transmission process are stopped by the stop or termination order of the LBS server ( 20 ).  
         [0043]     The location measurement and the location transmission between the mobile phone ( 10 ) and the LBS server ( 20 ) are performed by the connection with TCP/IP Protocol, HTTP Protocol or SOAP Protocol.  
         [0044]     The accuracy of the location information may be a management area of the switching system according to a service request, or it may be utilized as one area by combining several base stations together. Also, if the location information is used based on a base station, it may be ETDOA, TDOA, GPS (including AGPS) system, which are more accurate.  
         [0045]     Thus, as explained above, the conventional method performs the location information management in the LBS server and the communication between the LBS server and the terminal for location measurement every time, whereas the present invention minimizes the communications for the location measurement and management between a mobile phone and the LBS server, makes the location information acquisition and transmission management to be performed in a terminal, and transmits the location information to the LBS server only when it is necessary (i.e., if the conditions required by the LBS server is satisfied), thereby the location information can be timely acquired.  
         [0046]     As described above, the automatic location registration method of a mobile phone according to the present invention can be used not only for the hand-set based Cell-ID method and network based GPS method which are presently used domestically, but also for other methods for location measurement. Hence, the present invention is capable of reducing overload of position measurement server (PDE), switching system (MSC), base station system (BSC, BTS) and LBS server, while increasing their efficiency. Particularly, it is possible for the terminal by itself to calculate and decide location information, so that the overload applied to the HLR can be considerably reduced, and the overload applied to the PDE can be almost eliminated except for the overload consumed in TTFF (Time To First Fix).  
         [0047]     According to the request of a user, one or two operation(s) can be carried out individually. A simple key operation of a user enables the individual operation.  
         [0048]     Hence, according to the present invention, the overload of the system equipment can be minimized by the location information collection from the terminal. Accordingly, the service fee can be reduced, thereby it is expected that many position-based services, which were restricted by the expensive cost, can become available at a reasonable cost.  
         [0049]     Also, in the present invention, the application of a terminal is performed in the background state, and then periodically acquires and compares the position information to transmit the location information to the LBS server only if it satisfies conditions, so that the communications between the position acquisition server and the terminal can be minimized. Also, if a certain position is obtained, the position is registered at the LBS server as real time data, thereby the present invention can be applied to the zone based separation/arrival related services usefully.  
         [0050]     Although only one embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
