Referring to FIG. 4, in the present invention, rectangular region 430 is defined by latitude ranges Xi0 to Xi1 and longitude ranges Yi0 to Yi1. That is, the region 430 is represented by [Xi0, Yi0] to [Xi1 to Yi1]. “Area B” is given to the area 430 as an area ID for uniquely identifying the area 430.

  The stay determination unit 42 of the movement frequency information management server 40 holds map data that is partitioned by a rectangular region 430 shown in FIG. 4 and an area ID is assigned to each partitioned region.

  FIG. 5 is a conceptual diagram of staying in the areas of the mobile phone 10, the handheld PC 20, and the notebook PC 30. FIG. 6 is a conceptual diagram of movement between areas of the mobile phone 10, the handheld PC 20, and the notebook PC 30.

  Referring to FIG. 5, stay determination unit 42 receives terminal location information IFPT1 = [X1, Y1 / ID1 / t1], IFPT2 = [X2, Y2 / ID1 / t2], IFPT3 = [X3] from location information acquisition unit 41. , Y3 / ID1 / t3] sequentially.

  When stay determination unit 42 receives terminal position information IFPT1 = [X1, Y1 / ID1 / t1] from position information acquisition unit 41, stay determination unit 42 includes the position included in terminal position information IFPT1 = [X1, Y1 / ID1 / t1]. Information [X1, Y1] is extracted, and the map data held is referred to, and area A including the extracted position information [X1, Y1] is detected.

  After that, when the stay determination unit 42 receives the terminal location information IFPT2 = [X2, Y2 / ID1 / t2] from the location information acquisition unit 41, the stay determination unit 42 is included in the terminal location information IFPT2 = [X2, Y2 / ID1 / t2]. Position information [X2, Y2] is extracted, the map data held is referred to, and an area A including the extracted position information [X2, Y2] is detected.

  Subsequently, when the terminal location information IFPT3 = [X3, Y3 / ID1 / t3] is received from the location information acquisition unit 41, the stay determination unit 42 is included in the terminal location information IFPT3 = [X3, Y3 / ID1 / t3]. The position information [X3, Y3] is extracted, and the area B including the extracted position information [X3, Y3] is detected by referring to the held map data.

  Then, stay determination unit 42 indicates that mobile phone 10 has moved into area A at time t1, has stayed in area A at time t2, and has moved from area A to area B at a later time t3. Is detected.

  Referring to FIG. 6, stay determination unit 42 sequentially receives terminal location information IFPT4 = [X4, Y4 / ID1 / t4] and IFPT5 = [X5, Y5 / ID1 / t5] from location information acquisition unit 41.

  When stay determination unit 42 receives terminal position information IFPT4 = [X4, Y4 / ID1 / t4] from position information acquisition unit 41, stay determination unit 42 includes the position included in terminal position information IFPT4 = [X4, Y4 / ID1 / t4]. Information [X4, Y4] is extracted, and the map data held is referred to, and area A including the extracted position information [X4, Y4] is detected.

  After that, the stay determination unit 42 receives the terminal location information IFPT5 = [X5, Y5 / ID1 / t5] from the location information acquisition unit 41, and is included in the terminal location information IFPT5 = [X5, Y5 / ID1 / t5]. Position information [X5, Y5] is extracted, the map data held is referred to, and an area B including the extracted position information [X5, Y5] is detected.

  Then, stay determination unit 42 detects that mobile phone 10 has moved into area A at time t4 and then moved from area A to area B at time t2.

  In this way, the stay determination unit 42 sets a threshold value for each area, and if the time during which the mobile phone 10 or the like exists in the same area exceeds the threshold value, the mobile phone If it is determined that the mobile phone 10 or the like has stayed in the area and the time during which the mobile phone 10 or the like is in the same area is equal to or less than the threshold value, the mobile phone 10 or the like does not stay in the area. Is determined to have moved.

  FIG. 7 is a conceptual diagram of staying and moving in the areas of the mobile phone 10, the handheld PC 20, and the notebook PC 30. Referring to FIG. 7, for example, mobile phone 10 moves from position [X, Y] outside the area to position [X0, Y0] within area E, and then moves to area F and within area F. Stay (position [X10, Y10], [X11, Y11], [X12, Y12]), and then move to position [X30, Y30] in area G.

  FIG. 8 is a diagram for explaining a method of detecting a movement source and a movement destination. Referring to FIG. 8, after moving to area E, staying in area F and moving to area G described above with reference to FIG. 7, mobile phone 10 further moves to area H and stays in area H. .

  Then, stay determination unit 42 detects area F as the movement source out of areas F and H detected as the area where mobile phone 10 stayed, and detects area H as the movement destination.

  FIG. 9 is a conceptual diagram of the movement frequency registration table. FIG. 10 is a diagram illustrating movement between areas where the mobile phone 10, the handheld PC 20, and the notebook PC 30 stay.

  Referring to FIG. 9, movement frequency registration table 610 includes a movement source, a movement destination, and a movement frequency. The movement source, the movement destination, and the movement frequency are associated with each other.

  When the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay in one area and then move to another area, the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay first. It consists of the area ID of the area.

  When the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay in one area and then move to another area, the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay first. It consists of the area ID of the area that has moved from the area and stayed.

  The movement frequency consists of the number of movements between the corresponding movement source and movement destination.

  The movement source, the movement destination, and the movement frequency constitute movement frequency information related to the frequency of movement of the mobile phone 10 or the like between the areas where the mobile phone 10 or the like stayed, and the movement frequency registration table 610 stores the movement frequency information. It is expressed in tabular form.

  When the mobile phone 10, the handheld PC 20, and the notebook PC 30 stay in the area A and then move from the area A to the area B, the area ID “A” of the area A is stored in the movement source. “B”, which is the area ID of B, is stored in the movement destination, and “1”, which is the number of movements from the area A to the area B, is stored in the movement frequency.

  Further, when the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay in the area A and then move from the area A to the area C, “A” is stored in the movement source in the same manner, and “C” “Is stored in the movement destination, and“ 1 ”is stored in the movement frequency.

  Further, when the mobile phone 10, the handheld PC 20 and the notebook PC 30 stay in the area B and then move to the area A, “B” is stored in the movement source, “A” is stored in the movement destination, and “1” "Is stored in the movement frequency.

  When the cellular phone 10, the handheld PC 20 and the notebook PC 30 stay in the area A and then move to the area D, and when the cellular phone 10, the handheld PC 20 and the notebook PC 30 stay in the area C, then the area The same applies when moving to A and staying there.

  The movement frequency registration table 610 does not store frequency information related to movement between areas of the mobile phone 10 alone, but also stores frequency information related to movement between areas of the handheld PC 20 and the notebook PC 30.

  Therefore, when the stay determination unit 42 of the movement frequency information management server 40 receives the terminal location information IFPT from any one of the mobile phone 10, the handheld PC 20, and the notebook PC 30, the above-described determination is made based on the received terminal location information IFPT. By the method, the movement source and the movement destination of the mobile phone 10, the handheld PC 20, the notebook PC 30 and the like are detected, and the movement frequency between the detected movement source and the movement destination is increased by “1”. Then, stay determination unit 42 stores the detected area IDs of the movement source and the movement destination in “movement source” and “movement destination” of movement frequency registration table 610, respectively, and the increased values are stored in movement frequency registration table 610. Stored in “movement frequency”.

  Upon receiving the terminal position information IFPT, the stay determination unit 42 repeatedly executes this operation, and information regarding movement between areas of the terminal devices such as the mobile phone 10, the handheld PC 20, and the notebook PC 30 is stored in the movement frequency registration table 610 as needed. accumulate.

  As a result, for example, a movement frequency registration table 610 shown in FIG. 9 is created. Note that the movement frequency registration table 610 shown in FIG. 9 shows that the mobile phone 10, the handheld PC 20 and the notebook PC 30 move from the area A to the area B even when moving between the same two areas A and B. The mobile phone 10, the handheld PC 20, and the notebook PC 30 store the movement frequency separately from the case where the mobile phone 10, the handheld PC 20, and the notebook PC 30 move from area B to area A. That is, the movement frequency registration table 610 shown in FIG. 9 is a table that considers the movement directions of the mobile phone 10, the handheld PC 20, and the notebook PC 30.

  As described in FIG. 5, when the mobile phone 10, the handheld PC 20, and the notebook PC 30 move to, for example, the area A, the mobile phone 10, the handheld PC 20, and the notebook PC 30 A user of the mobile phone 10, the handheld PC 20, and the notebook PC 30 generally moves between areas to go to hospitals, schools, libraries, restaurants, and other facilities. Therefore, if the moving distance in the area A is short, the mobile phone 10, the handheld PC 20, and the notebook PC 30 stay in one facility.

  Therefore, the movement source and the movement destination of the movement frequency registration table 610 generally indicate each facility existing in each area.

  As a result, looking at the movement frequency registration table 610, the users of the mobile phone 10, the handheld PC 20, and the notebook PC 30 are from the facilities in the area A, the facilities in the area B, the area C and the area D, and the facilities in the area B. It can be seen that the facility in the area A and the facility in the area C have moved to the facility in the area A.

  Subsequently, generation of a destination area keyword in the area information search server 50 will be described. FIG. 11 is a conceptual diagram of an area ID definition table. FIG. 12 is a conceptual diagram of an area keyword definition table.

  Referring to FIG. 11, area ID definition table 410 includes an area ID, a latitude range, and a longitude range. The area ID, the latitude range, and the longitude range are associated with each other.

  The area ID includes identification information that uniquely identifies each area. The latitude range includes a latitude range in the area represented by the area ID. The longitude range includes a longitude range in the area represented by the area ID.

  Referring to FIG. 12, area keyword definition table 420 includes an area ID, an area keyword, and an area label. The area ID, area keyword, and area label are associated with each other.

  The area ID includes identification information that uniquely identifies each area. The area keyword is a keyword related to the area represented by the area ID. The area label is composed of words that simply express the area represented by the area ID.

  The area keyword generation unit 53 of the area information search server 50 holds an area ID definition table 410 and an area keyword definition table 420.

  FIG. 13 is a diagram for explaining a method of generating a destination area keyword. The area keyword generation unit 53 holds an area ID definition table 410-1 and an area keyword definition table 420-1 shown in FIG.

  A method of generating a destination area keyword will be described in detail by taking as an example a case where a search request SCHR that does not include a source area keyword is received. When generating the destination area keyword, the area keyword generation unit 53 acquires the movement frequency registration table 610 (see FIG. 9) from the movement frequency database 43.

  When the location information acquisition unit 51 receives the search request SCHR from the mobile phone 10, the location information acquisition unit 51 detects the location information [X, Y] included in the received search request SCHR and the identification information ID 1 of the mobile phone 10. The data is output to the generation unit 53.

  When the area keyword generation unit 53 receives the position information [X, Y] and the identification information ID1 from the position information acquisition unit 51, the area keyword generation unit 53 displays the latitude range and the longitude range including the received position information [X, Y] as an area ID definition table. Detect with reference to 410-1.

Position information [X, Y] in the "X" are included in the latitude range _{[Xi0 A,} Xi1 A], position information [X, Y] when the "Y" is included in the longitude range _{[Yi0 A,} Yi1 A] Then, the area keyword generating unit 53 refers to the area ID definition table 410-1 to detect the latitude range [Xi0 _A , Xi1 _A ] and the longitude range [Yi0 _A , Yi1 _A ], and the detected latitude range [ xi0 _a, detects the Xi1 _a] and longitude range _{[Yi0 a,} Yi1 a] in the corresponding area ID = a.

  Then, the area keyword generation unit 53 sets the area represented by the detected area ID = A as the movement source of the mobile phone 10.

  After that, the area keyword generating unit 53 refers to the movement frequency registration table 610 and detects the movement destination = B having the maximum movement frequency among the movement destinations corresponding to the detected movement source = A.

  Then, the area keyword generating unit 53 refers to the area keyword definition table 420-1 and detects the keyword = “Shinagawa, express” corresponding to the detected area B as the destination area keyword. That is, the area keyword generation unit 53 generates a destination area keyword.

The detected destination area keyword = “Shinagawa, express” is a keyword related to the area B represented by the latitude range [Xi0 _B , Xi1 _B ] and the longitude range [Yi0 _B , Yi1 _B ].

  Next, a method for generating a destination area keyword will be described in detail by taking as an example a case where a search request SCHR in which a source area keyword is specified is received. FIG. 14 is a diagram for explaining another method for generating a destination area keyword.

  Also in this case, the area keyword generation unit 53 acquires the movement frequency registration table 610 (see FIG. 9) from the movement frequency database 43.

  When receiving the search request SCHR from the mobile phone 10, the source area keyword acquisition unit 52 detects the source area keyword = “Yokohama” included in the received search request SCHR and the identification information ID 1 of the mobile phone 10. To the area keyword generation unit 53.

  When the area keyword generation unit 53 receives the movement source area keyword = “Yokohama” and the identification information ID1 from the movement source area keyword acquisition unit 52, the area keyword generation unit 53 refers to the area keyword ID definition table 420-2 and refers to the movement source area keyword = “ “Yokohama” in the area label column matching “Yokohama” is detected, and area C corresponding to the detected “Yokohama” is detected.

  Then, the area keyword generating unit 53 sets the detected area C as the movement source of the mobile phone 10.

  As described above, the area keyword generation unit 53 detects the movement source of the mobile phone 10 based on the movement source area keyword transmitted from the mobile phone 10.

  Thereafter, the area keyword generation unit 53 refers to the movement frequency registration table 610 and detects a movement destination having the maximum movement frequency among movement destinations corresponding to movement source = area C. In the case shown in FIG. 14, the area keyword generation unit 53 has the highest movement frequency among the movement destinations corresponding to the movement source = area C because the movement destination corresponding to the area C as the movement source is only the area A. The area A is detected as a movement destination.

  Subsequently, the area keyword generation unit 53 refers to the area keyword definition table 420-2, detects the “National Diet Building” corresponding to the area A, and generates the detected “National Diet Building” as the destination area keyword. .

  As described above, the area keyword generating unit 53 generates a destination area keyword based on the location information [X, Y] of the mobile phone 10 or the source area keyword specified by the user of the mobile phone 10.

  FIG. 15 is a flowchart for explaining the operation of constructing the movement frequency registration table 610. In FIG. 15, the operation of constructing the movement frequency registration table 610 will be described by taking as an example the case where the mobile phone 10 transmits the terminal location information IFPT.

  Referring to FIG. 15, when a series of operations is started, position information acquisition unit 103 of mobile phone 10 determines whether or not it is the transmission timing of position information (step S1). The position information acquisition unit 103 determines whether or not it is the transmission timing of the position information by determining whether or not the time measured using a built-in timer (not shown) has reached a predetermined transmission cycle. judge.

  When it is determined in step S1 that it is the transmission timing of the position information, the position information acquisition unit 103 acquires the position information [X, Y] by the GPS receiver (step S2), and uniquely identifies the mobile phone 10. Generating terminal location information IFPT = [X, Y / ID1 / t] consisting of identification information ID1 for identifying, time t when location information [X, Y] is acquired, and location information [X, Y], The generated terminal location information IFPT is output to communication section 101.

  The communication unit 101 of the mobile phone 10 receives the terminal location information IFPT from the location information acquisition unit 103 and transmits the received terminal location information IFPT to the movement frequency information management server 40 via the network 70 (step S3).

  The location information acquisition unit 41 of the movement frequency information management server 40 receives the terminal location information IFPT from the mobile phone 10 via the network 70 (step S4), and the location information [X, Y] from the received terminal location information IFPT. Is acquired (step S5).

  Then, the location information acquisition unit 41 of the movement frequency information management server 40 outputs the acquired terminal location information IFPT to the stay determination unit 42.

  The stay determination unit 42 of the movement frequency information management server 40 receives the position information [X, Y] from the position information acquisition unit 41 and detects the area RG including the received position information [X, Y] by the method described above. (Step S6).

  Thereafter, the stay determination unit 42 of the movement frequency information management server 40 determines whether or not the mobile phone 10 stays in the area RG by the method described above (step S7).

  When it is determined in step S7 that the mobile phone 10 has not stayed in the area RG, the series of operations ends.

  On the other hand, when it is determined in step S7 that the mobile phone 10 has stayed in the area RG, the stay determination unit 42 of the movement frequency information management server 40 indicates that the mobile phone 10 has stayed in the area RG. Is generated (step S8).

  And the stay determination part 42 of the movement frequency information management server 40 determines whether the area RG is a movement origin based on the produced | generated stay information (step S9).

  In this case, the stay determination unit 42 of the movement frequency information management server 40 determines that the area RG is the movement source when it is determined in step S7 that the mobile phone 10 has stayed in the area RG for the first time.

  The stay determination unit 42 of the movement frequency information management server 40 determines that the mobile phone 10 has stayed in the area RG in step S7 after the movement source of the mobile phone 10 has already been stored in the movement frequency registration table 610. At this time, it is determined that the area RG is the destination.

  When it is determined in step S9 that the area RG is the movement source, the stay determination unit 42 of the movement frequency information management server 40 registers the area RG as the movement source (step S10). Thereafter, the series of operations proceeds to step S13.

  On the other hand, when it is determined in step S9 that the area RG is not the movement source, that is, when it is determined that the area RG is the movement destination, the stay determination unit 42 of the movement frequency information management server 40 selects the area RG. Registration is made at the destination (step S11).

  Then, the stay determination unit 42 of the movement frequency information management server 40 increases the movement frequency from the movement source to the movement destination by “1”, and registers the increased value in “movement frequency” of the movement frequency registration table 610. (Step S12).

  The stay determination unit 42 of the movement frequency information management server 40 has already registered the movement source, the movement destination, and the movement frequency, and the movement frequency between the movement source and the movement destination that is the same as the registered movement source and movement destination. Is counted, the already registered movement frequency is incremented by “1”, and “movement frequency” in the movement frequency registration table 610 is updated.

  Then, after step S10 or step S12, the stay determination unit 42 of the movement frequency information management server 40 accumulates the movement frequency registration table 610 as the movement frequency database 43 (step S13). Thereafter, a series of operations ends.

  Note that the mobile phone 10, the handheld PC 20, the notebook PC 30 and the movement frequency information management server 40 repeatedly execute the flowchart shown in FIG. 15 to periodically transmit from the mobile phone 10, the handheld PC 20 and the notebook PC 30. A movement frequency registration table 610 is constructed based on the position information IFPT.

  The target keyword acquisition unit 104 acquires a keyword input by the user of the mobile phone 10 and outputs the acquired keyword to the search request unit 106 as the target keyword OKW. In this case, the user of the mobile phone 10 inputs the keyword “restaurant” in the input field 710 by looking at the input screen shown in FIG. The user of the mobile phone 10 inputs a keyword in the input field 710 and clicks “Go”.

  In this case, the user of the mobile phone 10 does not input anything in the input field 720 for inputting the movement source area keyword.

  The search request unit 106 receives the terminal location information IFPT from the location information acquisition unit 103, receives the target keyword OKW (= restaurant) from the target keyword acquisition unit 104, and receives the location information [ X, Y] and target keyword OKW (= restaurant) are generated, and the identification information ID1 of the mobile phone 10 is added to the generated search word information to generate a search request SCHR.

  Then, the search request unit 106 outputs the generated search request SCHR to the communication unit 101, and the communication unit 101 transmits the search request SCHR to the area information search server 50 via the network 70 (step S21).

  The location information acquisition unit 51 of the area information search server 50 receives the search request SCHR via the network 70 (step S22), and acquires location information [X, Y] from the received search request SCHR (step S23). The acquired position information [X, Y] is output to the area keyword generation unit 53.

  Thereafter, the area keyword generation unit 53 of the area information search server 50 acquires the movement frequency registration table 610 from the movement frequency information management server 40 (step S24). Then, the area keyword generation unit 53 of the area information search server 50 detects the area RG including the position information [X, Y] by the above-described method, and detects the area represented by the detected area RG as the movement source. (Step S25).

  Then, the area keyword generation unit 53 of the area information search server 50 refers to the movement frequency registration table 610 and detects a movement destination corresponding to the movement source (= area RG) (step S26). Then, the area keyword generation unit 53 of the area information search server 50 refers to the area keyword definition table 420 and detects an area keyword corresponding to the detected destination as a destination area keyword (step S27). As a result, the series of operations ends.

  Even when the handheld PC 20 and the notebook PC 30 transmit the search request SCHR specifying the location information, the destination area keyword is generated according to the flowchart shown in FIG.

  FIG. 18 is a flowchart for explaining another operation for generating a destination area keyword. FIG. 19 is a diagram illustrating another example of the input screen in the mobile phone 10, the handheld PC 20, and the notebook PC 30.

  Note that the flowchart shown in FIG. 18 is a flowchart for explaining the operation of generating a destination area keyword when the mobile phone 10 transmits a search request SCHR specifying the source area keyword.

  When a series of operations is started, the user of the mobile phone 10 inputs “restaurant” in the input field 710 shown in FIG. 19 and inputs “Hiroshima Airport” in the input field 720. Then, the user of the mobile phone 10 clicks “Go”.

  Then, the target keyword acquisition unit 104 of the mobile phone 10 acquires “restaurant” input in the input field 710 as the target keyword OKW, and outputs the acquired target keyword OKW (= restaurant) to the search request unit 106.

  The source area keyword acquisition unit 105 of the mobile phone 10 acquires “Hiroshima Airport” input in the input field 720 as the source area keyword SKW, and the acquired source area keyword SKW (= Hiroshima Airport). Output to the search request unit 106.

  The search request unit 106 of the mobile phone 10 receives the target keyword OKW (= restaurant) from the target keyword acquisition unit 104 and receives the source area keyword SKW (= Hiroshima Airport) from the source area keyword acquisition unit 105. Then, the search request unit 106 of the mobile phone 10 generates search word information composed of the target keyword OKW (= restaurant) and the movement source area keyword SKW (= Hiroshima Airport), the generated search word information, A search request SCHR including the identification information ID for uniquely identifying the telephone 10 is generated. Thereafter, the search request unit 106 of the mobile phone 10 outputs the generated search request SCHR to the communication unit 101.

  The communication unit 101 of the mobile phone 10 receives the search request SCHR from the search request unit 106 and transmits the received search request SCHR to the area information search server 50 via the network 70. That is, the mobile phone 10 transmits a search request SCHR specifying the movement source area keyword to the area information search server 50 (step S31).

  The area information search server 50 receives the search request SCHR from the mobile phone 10 via the network 70 (step S32). Then, the movement source area keyword acquisition unit 52 of the area information search server 50 acquires the movement source area keyword SKW from the search request SCHR (step S33), and outputs the acquired movement source area keyword SKW to the area keyword generation unit 53. To do.
