  Next, the operation of the system will be described in detail with reference to FIGS. 6 and 12.

  First, the user 31 requests the IP-PBX 14 to download the data 32 from the mobile terminal 17 (step S1).

  After receiving the download request, the IP-PBX 14 downloads the data 32 from the server 16, assigns a data ID to the data 32 as a logical identifier for identifying the data 32, and temporarily stores it (step S2).

  At this time, as mentioned in the preconditions, the IP-PBX 14 recognizes the moving speed and position information of the user 31 and the transmission speed of the APs 18, 19, 20, 21, and 22, and the mobile terminal within the area of the AP 18 17 calculates the data capacity that can be downloaded (step S3), and compares the data capacity of the data 32 with the data capacity that can be downloaded in the area of the AP 18 (step S4). At this time, if there is temporarily stored data in the AP 18, the data capacity is added to the data 22 for comparison.

  As a result, if it is determined that the data capacity that can be downloaded by the mobile terminal 17 in the area of the AP 18 is larger than the data capacity of the data 32 and the download can be completed in the area of the AP 18, the data 32 is stored in the AP 18. It transfers to the portable terminal 17 via (step S5). When the data transfer is completed, the temporary file of the data 32 stored in the IP-PBX 14 is deleted (step S6).

  On the other hand, if it is determined that the data capacity of the mobile terminal 17 in the area of the AP 18 is smaller than the data capacity of the data 32 and the download cannot be completed in the area of the AP 18, the IP-PBX 14 Using the terminal ID of 17, the AP-ID 25 of the current area, and the current time 41 as keys, the mobile terminal 17 is searched for time-dependent travel route history information from the database 5 (step S 7), and the AP 19 is predicted as the next destination AP. (Step S8).

  Then, the data capacity that the portable terminal 17 is capable of within the area of the AP 19 is calculated from the moving speed and position information of the user 31 and the transmission speed of the AP 19 (step S9), and the data capacity of the data 32 and the areas of the APs 18 and 19 are calculated. The total amount of data that can be downloaded is compared (steps S10 and S11). At this time, if there is temporarily stored data in the APs 18 and 19, the data capacity is added to the data 32 for comparison.

  As a result, when it is determined that the total data capacity that can be downloaded in the areas of the APs 18 and 19 is smaller than the data capacity of the data 32 and the download cannot be completed in the area of the AP 19, the IP-PBX 14 Then, by using the terminal ID 24 of the mobile terminal 17, the AP-ID 26 of the current area, and the current time 41 as keys, the travel history information by time of the mobile terminal 17 is searched from the database 15 (step S 7), and is used as the next destination AP. AP20 is predicted (step S8).

  Then, the data capacity that can be downloaded by the mobile terminal 17 within the area of the AP 20 is calculated from the moving speed and position information of the user 31 and the transmission speed of the AP 20 (step S9), and the data capacity of the data 32 and the APs 18, 19, 20 are calculated. The total data capacity that can be downloaded in the area is compared (steps S10 and S11). At this time, if temporarily stored data exists in the APs 18, 19, 20, the data capacity is added to the data 32 for comparison.

  As a result, if it is determined that the total data capacity that can be downloaded in the areas of the APs 18, 19, and 20 is larger than the data capacity of the data 32 and the download can be completed in the area of the AP 20, the IP− The PBX 14 divides the data 32 into divided data 34, 35, and 36 that can be downloaded in the areas of the APs 18, 19, and 20 (step S12), and assigns divided data IDs 37, 38, and 39 for identifying each of them. Assign (step S13).

  At the same time, the IP-PBX 14 registers the divided data information in the database 15 (step S14). Then, the IP-PBX 14 transfers the divided data 34, 35, and 36 to the APs 18, 19, and 20, respectively (step S15). At this time, in each divided data, the request terminal ID is the terminal ID 24, the original data ID is the data ID 33, and the number of divisions of the original data is 3. The APs 18, 19, and 20 reflect the data capacity of the received divided data in the total temporarily stored data capacity of the AP information (step S16), and temporarily hold the divided data 34, 35, and 36 (step S17).

  When the APs 18, 19, and 20 authenticate the portable terminal 17 having the terminal ID 24 that matches the requested terminal ID in the divided data information held by each of the APs 18, 19, and 20 in its own area (step S18), the APs 18, 19, and 20 Data is transferred (step S19). The portable terminal 17 confirms the original data ID of the divided data and the number of divisions of the original data (step S20), and restores the original data 32 when all the divided data are prepared (step S21).

  When the restoration of the original data 32 is completed, the portable terminal 17 transmits a completion notification to the IP-PBX 14 (step S22).

  Upon receiving the completion notification from the mobile terminal 17, the IP-PBX 14 transmits a request for deleting the divided data 34, 35, 36 to the AP 18, 19, 20 and the AP 18, 19, 20 that has received the request for deleting the divided data. Deletes the divided data 34, 35, and 36 respectively held (step S23). Then, the data temporarily held by the IP-PBX 14 is deleted (step S24).

  With the above operation, the download process of the data 33 by the portable terminal 17 is completed.

  Next, a second embodiment of the data acquisition system according to the present invention will be described. In the travel route prediction step in the above-described embodiment, the IP-PBX 14 predicts the travel route depending only on the past travel route information of the mobile terminal 17, but has received a download request from the mobile terminal 17. At this time, it is possible to determine the route surely by providing the mobile route information list held by the IP-PBX 14 to the portable terminal 17 and selecting and notifying the user of the desired route from the list. is there.

  With reference to FIG. 13 to FIG. 17, the movement route prediction operation in the second exemplary embodiment will be described. Other operations are the same as those described above, and will not be described.

  When receiving a download request from the mobile terminal 17, the IP-PBX 14 transmits a location keyword list to the user 31 and inquires about the destination (step S25).

  After receiving the position keyword list, the user 31 selects a position keyword from the list and returns it to the IP-PBX 14 (step S26).

  The IP-PBX 14 that has received the location keyword of the destination searches the past travel route history information for the location keyword selected by the user 31 using the user location information and the location keyword as keys (step S27), and obtains the result. It transmits to the user 31 (step S28).

  When receiving the travel route history information, the user 31 selects a desired route from the travel route history information, and sends it back to the IP-PBX 14 (step S29).

  By performing the above operation as a pre-process between step S1 and step S2 in FIG. 12, it is possible to unify the will regarding the movement route between the IP-PBX 14 and the user 31, so steps S7 and S8. Therefore, the reliability of subsequent download processing is improved, and the load and cost of the IP network can be minimized.
