Description

  The present invention relates to a position information notification system that uses position information obtained by a mobile communication terminal to notify various position information corresponding to the position, and in particular, a position information notification server and a mobile communication terminal used in this system. It is related with the technology which realizes efficient operation.

  As is well known, a mobile telephone system using a PHS (Personal Handyphone System) system has a function of identifying position information of each terminal. Even in a mobile phone system, it has become possible to acquire position information of each terminal by using a GPS (global positioning system).

  Conventionally, various position information notification systems using such position information of mobile communication terminals have been constructed. For example, there is a system that manages the current position of a taxi at the center and efficiently dispatches vehicles, a system that provides information on stores that exist near the current position of the user, and the like.

  In such a position information notification system, the problem is how to set the timing for updating the content information to be notified as the user moves. That is, since the user does not know how much the content information changes after moving, it is necessary to access the server periodically or every time the terminal moves a certain distance. On the other hand, on the server side, even if the terminal position is not out of the management area and the content information to be notified does not change, the server must respond to the access request.

  From the above, a method in which the mobile communication terminal notifies the center server of the current position efficiently has been studied. For example, the range in which the terminal moves is divided into a plurality of areas in advance, and a method of notifying the server of the current position when the terminal moves from the current area to another adjacent area, or the server transmits area information to the terminal. A method for notifying the server of the current position when the terminal is out of the area has been proposed.

  However, in the above-described conventional technology, the terminal side must have in advance information on the area and program information for determining whether the server is out of the notified area. For this reason, there is a problem that it is difficult to change the information of the area and the judgment program.

  In particular, since a terminal can use only a specific server corresponding to the area information and program information that it has, when constructing a system that uses multiple servers that manage areas in different ways, respectively. However, there is a problem that the terminal has to have area information and determination program information corresponding to each server, which increases the burden on the terminal side.

  As described above, in the conventional position information notification system, the mobile communication terminal side has condition determination information such as conditions for notifying the current position in advance (for example, range information of areas, etc.) and programs for condition determination. Therefore, there is a problem that it is difficult to change conditions and condition determination information. In addition, there is a problem that the terminal can use only a specific server corresponding to the held condition and condition determination information, and cannot use a server that manages the condition by a different method. In particular, if the distance between the locations of each store is large with respect to the interval for acquiring the current position and the moving speed of the mobile communication terminal device, even if the position information is notified each time the position is acquired, the server There is no change in the store information searched on the side, the amount of communication is unnecessarily increased, and the load on the server is also increased.

  Therefore, the present invention solves the above-described problem and efficiently notifies the position information and receives information corresponding to the position information from the server even if the condition information and condition determination information for notifying the position information are not previously provided. An object of the present invention is to provide a mobile communication terminal device that can reduce the amount of unnecessary communication by limiting the notification of position information according to the moving speed.

  In order to achieve the above object, a mobile communication terminal apparatus according to the present invention has the following characteristic configuration.

  (1) A mobile communication terminal device that notifies location information to a server and acquires information corresponding to the location information, and stores location information acquisition means for acquiring location information of the device itself and conditions based on the moving speed. And a storage unit, and a control unit that controls to notify the server of the position information acquired by the position information acquisition unit when it is determined that the condition based on the moving speed is satisfied.

  (2) In (1), the condition stored in the storage means is acquired from a server.

  (3) In (1), when the apparatus further includes a movement speed acquisition unit that acquires the movement speed of the device itself, and the control unit determines that the condition based on the movement speed is satisfied, the position information is stored in the server And the server is notified of the moving speed of the device.

  (4) In (1), the position information acquisition means is activated at regular time intervals.

  According to the present invention, it is possible to efficiently notify position information, receive information according to the position information from the server, and to move even if the condition information and condition determination information for notifying the position information are not provided in advance. It is possible to provide a mobile communication terminal apparatus capable of reducing useless communication volume by restricting notification of position information according to speed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system diagram showing a configuration of an embodiment of a position information notification system according to the present invention. This system is a store information notification service system that provides store information (content information) in the vicinity of a user's current position in a push manner. That is, a mobile communication terminal (hereinafter referred to as a client terminal) C possessed by a user automatically receives a location information notification server (hereinafter referred to as an information providing server) S through a network N such as a public network, regardless of the user's operation. The current position is notified to the server S, the information database D is searched based on the current position notified by the server S, the store information existing near the position is determined, and the service is transmitted to the client terminal C. is there.

  In the system configuration described above, the client terminal C includes a position acquisition unit activation unit PGK, a position acquisition unit PG, a position information notification unit PN, a condition determination unit CJ, an information reception unit IR, and an information display unit IV. The information providing server S includes a position information receiving unit PR, an information searching unit IR, a condition determining unit CD, a condition determining means managing unit CJM, and an information transmitting unit IS.

  Hereinafter, the information contents of the information database D, the information providing server S, and each functional unit in the client terminal C will be described in order.

  First, the information content of the information database D will be described.

  Store information is stored in the information database D in advance. The store information includes information regarding the location of the store. The information about the position may be in any format. For example, the name of the nearest station, latitude / longitude information, and the like can be considered. FIG. 2 shows an example of the store information storage format when the information regarding the store location is the nearest station name, and FIG. 3 shows an example of the store information storage format in the case of latitude and longitude information.

  When storing information using the nearest station name, a table relating to the location of the station is also prepared. This table manages station position information and information on the range in which the station is the nearest station. This position information may be in any format. For example, latitude / longitude information, PHS base station ID, and the like are conceivable. In the example of FIG. 2, latitude / longitude information is stored.

  The range information may be in any format as long as it is the minimum necessary information for specifying the range. For example, if the range is represented by a circle, the latitude and longitude information of the center point and the radius of the circle, if represented by a rectangle, the latitude and longitude information of each vertex, if represented by a polygon, vector information that connects the vertices, etc. It is done. In addition, a PHS base station ID included in the range is also conceivable. In the example of FIG. 2, the range is represented by a circle, and latitude / longitude information of the center point and information of the radius of the circle are stored.

  Next, each functional unit of the information providing server S will be described.

  The position information receiving unit PR has a function of receiving the position information of the client terminal C notified by the client terminal C. The position information may be in any format. For example, latitude / longitude information, PHS base station ID, and the like are conceivable.

  The information search unit IR has a function of searching for information from the information database D, and searches for stores near the location of the client terminal C received by the location information receiving unit PR.

  For example, when store information is stored in the information database D in the format of FIG. 2 and the current position of the client terminal C is represented by latitude and longitude information, first, the client terminal is used using the location information of each station in the station information table. Calculate the distance from C to each station and determine the nearest station. Next, a store whose nearest station matches the nearest station of the client terminal C is taken out from the store information table.

  When the store information is stored in the information database D in the format of FIG. 3, the distance from the client terminal C to each store is calculated, for example, a store within a certain distance from the current position of the client terminal C, the client A certain number of stores are taken out from the one close to the current position of the terminal C.

  The condition determining unit CD has a function of determining a condition that the client terminal C should next notify position information. The details of the condition determination will be described below with a specific example.

  First, when store information is stored in the information database D in the format of FIG. 2, the store information searched by the information search unit IR even if the client terminal C repeatedly notifies the location information at the position where the nearest station is the same. There is no change. Such a position notification unnecessarily increases the amount of communication and increases the load on the information providing server S.

  In this case, notification may be made when the nearest station is out of the same range. Therefore, the condition determination unit CD acquires the range information of the nearest station of the client terminal C obtained by the information search unit IR from the information database D and sets it as a condition to be notified that the range is represented by this information. In addition, the station information table in FIG. 2 may be configured to manage information on adjacent ranges, and set a condition for notifying that the range is represented by information on adjacent ranges.

  Further, store information is stored in the information database D in the format of FIG. 3, and information on stores within a certain distance from the current position of the client terminal C or a certain number of stores from near is provided to the client terminal C. Even in such a case, the same problem as described above occurs. That is, if the distance between the locations of each store is large with respect to the interval for acquiring the current position and the moving speed of the client terminal C, the information search is performed even if the position information is notified each time the position is acquired. The store information searched by the part IR remains unchanged, and the amount of communication is increased unnecessarily and the load on the server is also increased.

  Therefore, when the information search unit IR searches for a store within a certain distance from the current position of the client terminal C, for example, as shown in FIG. Find the value that is the shortest distance from the current position, find the value obtained by subtracting the constant distance from that distance, and the condition that you should be notified that you are more than the distance of the value obtained from the point where you first notified the current position To do.

  When the information search unit IR searches for a certain number of stores from those close to the current location of the client terminal C, for example, as shown in FIG. 5, the store closest to the location notified from the client terminal C It is set as a condition that should be notified that the distance from the point where the notification is made is more than the determined distance.

  4 and 5 each require a range that can be surely notified that notification is not necessary. In addition to such a condition determination method, it may be possible to determine the condition in consideration of the moving speed and moving direction of the client terminal C.

  The condition determination means management unit CJM has a function of managing information related to means for the client terminal C to make a condition determination. This information can be in any format. For example, a calculation formula, a program that actually performs a determination process, or the like can be considered.

  The means for performing the condition determination largely depends on the format of the store location information stored in the information database D. When the store information is stored in the format of FIG. 2, the distance between the two points is obtained from the latitude / longitude information of the client and the latitude / longitude information of the center point of the circle given as the range information. This is a calculation formula or the like for checking whether the radius is longer than the radius of the circle given as the range information.

  The information transmission unit IS has a function of transmitting information to the client terminal C. This information includes store information searched by the information search unit IR, information on a condition determined by the condition determination unit CD, which the client terminal C should next notify the location information, and a condition determination means management unit CJM. Information regarding the managed means for the client terminal C to make a condition determination is included.

  Subsequently, each functional unit of the client terminal C will be described.

  The position acquisition unit activation unit PGK has a function of activating the position acquisition unit PG. Any method may be used to determine activation. For example, there are a method of starting at a constant time interval, a method of starting when a certain condition is satisfied, and the like.

  The position acquisition unit PG has a function of acquiring the current position of the client terminal. Any means may be used for acquiring the position information. For example, there are a method of acquiring latitude / longitude information using GPS and a method of acquiring a PHS base station ID.

  The position information notification unit PN has a function of transmitting the position information acquired by the position acquisition unit PG to the information providing server S.

  The condition determination unit CJ has a function of determining whether to notify position information using the condition determination unit specified from the information providing server S based on the condition specified from the information providing server S. The conditions specified by the information providing server S and the condition determining means are acquired from the information receiving unit IR.

  The information receiving unit IR has a function of receiving information transmitted from the information providing server S. This information includes store information, information related to conditions for which position information should be notified next, and information related to means for making a condition determination. The store information is transferred to the information display unit IV, and the condition and condition determination means are transferred to the condition determination unit CJ.

  The information display unit IV has a function of displaying the store information notified from the information providing server S in a format that is easy for the user to view. This store information is acquired from the information receiving unit IR.

  In the system of FIG. 1, the flow of processing when the client terminal C receives the information providing service will be described below. Here, in the client terminal C, it is assumed that the position acquisition activation unit PGK activates the position acquisition unit PG at regular time intervals from the start of receiving services.

Client terminal C side (1) When receiving an instruction to receive an information service by a user operation, the position acquisition activation unit PGK activates the position acquisition unit PG.

  (2) The position acquisition unit PG acquires information on the current position of the client terminal C and passes it to the position information notification unit PN.

  (3) The location information notification unit PN accesses the information providing server S and transmits the location information acquired in (2).

Information providing server S side (4) The position information receiving unit PR receives the position information in response to the access from the client terminal C and passes it to the information searching unit IR.

  (5) The information search unit IR searches the information database D for information on stores existing near the current position of the client terminal C based on the position information acquired in (4), and the search result is used as the condition determination unit CD. To the information transmission unit IS. Subsequently, the condition determination unit CD determines, based on the search result, a condition for the client terminal C to notify the next position information, and passes the determined condition to the condition determination means management unit CJM and the information transmission unit IS. . The condition determination means management unit CJM passes information on the means for the client terminal C to determine the determined condition to the information transmission unit IS.

  (6) The information transmission unit IS transmits to the client terminal C information regarding the store information and conditions acquired in (5) and means for the client terminal C to make a condition determination.

Client terminal C side (7) The information receiving unit IR receives the store information, conditions, and condition determining means transmitted from the information providing server S, passes the store information to the information display unit IV, and sets the conditions and condition determining means. It passes to judgment part CJ.

  (8) The information display unit IV displays store information.

  (9) The position acquisition activation unit PGK activates the position acquisition unit PG after a predetermined time from when the position acquisition activation unit PG was activated last time.

  (10) The position acquisition unit PG acquires information on the current position of the client terminal C, passes it to the position information notification unit PN, and calls the condition determination unit CJ.

  (11) The condition determination unit CJ determines whether or not to notify the position information based on the condition and condition determination means given from the server S. If the condition determination unit CJ determines that notification is to be made, the processing from (3) onward is repeated. If it is determined not to notify, the processing from (9) onward is repeated.

  As described above, by dynamically specifying the conditions for the server S to notify the client terminal C of the position information, the client terminal C can notify the server S of only the position information useful for the server S. Become. As a result, it is possible to reduce the amount of communication for notification of position information and reduce the load on the server S. Further, the server S also provides means for making a condition determination, so that the client terminal S can flexibly cope with a change in the data format. As shown in FIG. 6, a plurality of servers SA (determination information: latitude and longitude of the circle center point) And radial distance, determination means: f (x, y)), SB (determination information: latitude and longitude of rectangular vertex, determination means: g (x, y)), SC (determination information: set of vectors, determination means: h (x, y)), ... can also be used.

  By the way, in the above embodiment, the information database D stores the position information in a format based on the latitude and longitude information as shown in FIG. 2, whereas the position information notified from the client terminal C is the base station ID. In such a case, the server S needs to obtain latitude / longitude information from the base station ID.

  As a method for realizing this, there is a method of creating a table for managing the ID of the base station and the latitude / longitude information of the existing position as shown in FIG. When the information search unit IR of the server S receives the information of the base station ID notified by the client from the position information receiving unit PR, the information search unit IR acquires the latitude / longitude information of the corresponding base station using the table of FIG. The store information is searched using the information as in the above embodiment.

  In the above-described embodiment, the method in the case where the condition determination unit CD and the condition determination unit management unit CJM all use latitude / longitude information has been described. However, as described above, the position information acquired and notified by the client terminal C Is a base station ID, the condition determination cannot be performed in the client terminal C if the method for determining the condition is based on the latitude and longitude information.

  Therefore, when the position information notified from the client terminal C is a base station ID, a condition for determining whether or not to notify the position information using the base station ID, and a condition determination means include an information providing server. S is provided to the client terminal C.

  As a method of realizing this, there is a method of managing range information using base station IDs as shown in FIG. 8 in the station information table of FIG. In addition, a method of dynamically obtaining the ID of the base station included in the range shown in FIG. 2 using the range information in the station information table in FIG. 2 and the base station information in FIG.

  In this way, the server S changes the format of the condition notification condition for the location information notified by the client terminal C according to the format of the location information notified by the client terminal C. Only the location information useful for S can be notified to the server S by the client terminal C, the amount of communication for notification of location information can be reduced, and the load on the server S can be reduced.

  Further, in the above embodiment, when the data format stored in the information database D is unified in the table, and the information providing server that is frequently connected while the client terminal C is receiving services is not changed, It is not necessary for the information providing server S to transmit information related to the condition determination every time the location information notification is sent from the client terminal C.

  Therefore, as shown in FIG. 9, a condition determining means requesting unit CJS is added to the client terminal C of FIG. 1, and a condition determining means answering unit CJR is added to the information providing server S.

  The condition determination means request unit CJS of the client terminal C has a function of requesting the information providing server S to provide a means for determining the position information notification condition and receiving the determination means as a response. When requesting the provision, information necessary for the information providing server S to select the determination means is also passed. As this information, for example, information on the format of position information that can be acquired by the client terminal C can be considered. The determination means received from the information providing server S passes to the condition determination unit CJ.

  The condition determination means reply unit CJR of the information providing server S has a function of receiving a request for provision of means for determining the position information notification condition from the client terminal C and replying an appropriate determination means to the client terminal C. Based on the information transmitted from the client terminal C, a determination unit suitable for the client terminal C is acquired from the condition determination unit management unit CJM.

  A processing flow when the client terminal C receives the information providing service in FIG. 9 will be described below. Here, it is assumed that the position acquisition unit PG is activated at regular time intervals from when the position acquisition activation unit PGK starts to receive services.

Client terminal C side (1) When receiving an instruction to receive an information service by a user's operation, the condition determining means requesting unit CJS accesses the information providing server S and requests the condition determining means answering unit CJR to provide the determining means. Do.

Information providing server S side (2) By access from the client terminal C, the condition determining means answering unit CJR acquires the determining means from the condition determining means managing unit CJM and transmits it to the condition determining means requesting unit CJS of the client terminal C. .

Client terminal C side (3) The condition determining means requesting unit CJS receives the determining means from the condition determining means answering unit CJR of the server S and passes it to the condition determining unit CJ.

  (4) The position acquisition activation unit PGK activates the position acquisition unit PG.

  (5) The position acquisition unit PG acquires information on the current position of the client terminal C and passes it to the position information notification unit PN.

  (6) The location information notification unit PN accesses the information providing server S, and transmits the location information acquired in (5) to the location information receiving unit PR.

Information providing server S side (7) The position information receiving unit PR receives the position information in response to the access from the client terminal C and passes it to the information searching unit IR.

  (8) Based on the location information acquired in (7), the information search unit IR searches the information database D for store information existing near the current location of the client terminal C, and uses the search results as the condition determination unit CD. To the information transmission unit IS. Subsequently, the condition determination unit CD determines a condition for the client terminal C to notify the next position information based on the search result, and passes the determined condition to the information transmission unit IS.

  (9) The information transmission unit IS transmits the store information and conditions acquired in (8) to the client terminal C.

Client terminal C side (10) The information receiving unit IR receives the store information and conditions transmitted from the information providing server S, passes the store information to the information display unit IV, and passes the conditions to the condition determining unit CJ.

  (11) The information display unit IV displays store information.

  (12) The position acquisition activation unit PGK activates the position acquisition unit PG after a predetermined time from when the position acquisition activation unit PG was activated last time.

  (13) The position acquisition unit PG acquires information on the current position of the client terminal C, passes it to the position information notification unit PN, and calls the condition determination unit CJ.

  (14) The condition determining unit CJ determines whether or not to notify the position information based on the condition and condition determining means given from the server S. If it is determined that notification is to be made, the processing from (6) onward is repeated. If it is determined not to notify, the processing from (12) onward is repeated. In the middle, when changing the information providing server, the processing from (1) is repeated.

  In this way, the means for dynamically specifying the conditions for the server S to notify the client terminal C of the position information and performing the condition determination is the server S when the client terminal C first connects to the server S. To the client terminal C, the client terminal C can notify the server S of only location information useful for the server S while minimizing the amount of data communication necessary for condition notification. The amount can be reduced and the load on the server can be reduced.

  The position information notification system having the above-described configuration can be applied to various services because an area for providing information can be set in an arbitrary format.

  For example, application to advertising services can be considered.

  In a supermarket or the like, it may be possible to present to a user within a radius of 2 km from the store. In this case, the area can be represented by a circle (FIG. 6A).

  If the territory is fixed, such as a home delivery pizza, the area may be represented by a rectangle (FIG. 6B).

  If it is a store in a station building, not only the vicinity of the station but also the presentation to the user in the train is effective. In such a case, the area cannot be expressed by a simple circle or rectangle. Therefore, the region is expressed by a technique such as a vector set (FIG. 6C).

  As described above, the position information notification system according to the present invention is particularly effective when it is necessary to handle a plurality of areas.
