<Search server>
The search server 400 stores application information. The application information includes, as information elements, an application name, a description, an image, a price, a rate, the number of downloads, and a review comment.

  Further, for each application, the search server 400 associates the information element of the application with the number of times of search that should be a trigger for updating the information element (hereinafter referred to as “update trigger search frequency”). A table (hereinafter referred to as an “information element update frequency correspondence table”). The update trigger search count may be different for each application. This is because it is assumed that the update frequency varies depending on the type of application.

  FIG. 3 shows an example of the information element update frequency correspondence table. FIG. 3 also shows the update frequency corresponding to the information element. It is sufficient that at least the information element and the update trigger search count are included.

  The information element update frequency correspondence table shown in FIG. 3 includes, as information elements, “application name”, “description”, “image”, “price”, “rate”, “download count”, and “review comment”. The update frequency is “low”, “low”, “low”, “medium”, “high”, “high”, and “high”, and the update trigger search frequency is “X”, “X”, “X”, “Y”, “Z”, “Z”, and “Z” are associated with each other. These are examples and can be changed as appropriate.

  The “application name”, “description”, and “image” are assumed to be relatively infrequently updated. Therefore, the update frequency is set to “low”.

  Also, the reason why the update frequency corresponding to “price” is “medium” is that the price fluctuation depends on the currency rate fluctuation.

  Also, the reason why the update frequency corresponding to “rate” is “high” is that it fluctuates depending on the degree of spread of applications. It is assumed that the update rate of the “rate” decreases as time passes after the application is registered. This is because the rate population is assumed to be small because the population of the rate increases as time elapses.

  Also, the reason why the update frequency corresponding to the “number of downloads” is “high” is that it fluctuates depending on the degree of spread of applications. This is because the “number of downloads” is assumed that the number of downloads decreases as time passes after the application is registered.

  The reason why the update frequency corresponding to the “review comment” is “high” is that it fluctuates depending on the degree of spread of the application and the elapsed time since the update. The “review comment” is assumed to update less frequently as time passes after the application is registered. This is because the number of “review comments” posted is expected to decrease as time elapses.

  The number of update trigger searches is preferably X> Y> Z. As the update frequency increases, the probability that the information element related to the application is updated increases in the distribution server 100. Therefore, the update frequency in the search server 400 is increased by reducing the number of update trigger searches. This is because it is preferable.

  By changing the trigger to be updated for each information element of the application, the update timing can be made different for each information element. Since information elements that are assumed to have a high update frequency are updated in a short period of time, the minimum information elements can be updated. Therefore, the crawling load on the search server 400 can be reduced, and further the network load can be reduced.

  The search server 400 receives an application search request from the mobile terminal 300. The search server 400 searches for an application in response to the application search request. The search server 400 transmits an application search response to the mobile terminal 300. The application search response includes the application to be presented.

  The search server 400 counts, for each application, the number of times selected as an application to be presented as a result of the search (hereinafter referred to as “number of searches”). It is determined whether there is an information element that has reached the number of times.

  When it is determined that there is an information element whose search count has reached the update trigger search count, the search server 400 requests the distribution server 100 to request the information element in order to update the information element. Send element acquisition request. The search server 400 updates the information element of the corresponding application based on the application information element acquisition response notified from the distribution server 100 as a response signal of the application information element acquisition request.

<Operation of wireless communication system>
FIG. 5 shows an embodiment of the operation of the wireless communication system.

  The portable terminal 300 transmits an application search request to the search server 400 (step S502). That is, when a user performs a predetermined operation for searching for an application, an application search request is transmitted from the transmission / reception unit 302 of the mobile terminal 300 to the search server 400.

  The search server 400 transmits an application search response as a response to the application search request from the mobile terminal 300 (step S504). That is, the distribution information selection unit 408 refers to the application stored in the application information storage unit 406 and selects an application to be presented by a predetermined selection method. The application list generation unit 410 generates an application list that includes the application selected by the distribution information selection unit 408. The application list generated by the application list generation unit 410 is transmitted from the transmission / reception unit 402 to the mobile terminal 300.

  The portable terminal 300 transmits an application detailed information request to the distribution server 100 (step S506). When a user selects a desired application by referring to the application list, the application information request unit 306 generates an application detailed information request in order to request detailed information of the desired application. The application detailed information request is input to the control unit 304 and transmitted from the transmission / reception unit 302 to the distribution server 100.

  In accordance with the application detailed information request from the mobile terminal 300, the distribution server 100 generates an application detailed information response including detailed information on the desired application requested by the application detailed information request. The application detailed information response is transmitted to the mobile terminal 300 (step S508). When the distribution server 100 does not have the application requested by the application detailed information request, the distribution server 100 generates an application detailed information response including information indicating that the application is not included. Distribution server 100 transmits an application detailed information response to portable terminal 300.

  The search server 400 increases the number of searches for the application to be presented that should be included in the application search response transmitted to the mobile terminal 300 in step S504. As a result of increasing the number of searches, it is determined whether there is an information element whose number of searches is equal to or greater than the number of update trigger searches (step S510). That is, the information element update determination unit 412 increases the number of searches corresponding to the application to be presented input by the distribution information selection unit 408. The information element update determination unit 412 refers to the information element update frequency correspondence table to be stored in the application information storage unit 406, and determines whether there is an information element whose search count is equal to or greater than the update trigger search count.

The information element update determination unit 412 refers to the information element update frequency correspondence table to be stored in the application information storage unit 406, and determines whether there is an information element whose search count is equal to or greater than the update trigger search count.

  If it is determined that there is no information element whose search count is equal to or greater than the update trigger search count (step S706: NO), the process ends. That is, the process of searching for an application is continued. On the other hand, when it is determined that there is an information element whose search count is equal to or greater than the update trigger search count (step S706: YES), the search server 400 informs the mobile terminal 300 that the search count is equal to or greater than the update trigger search count. In order to acquire the application information element acquisition request is transmitted (step S708).

  In response to the application information element acquisition request from the search server 400, the portable terminal 300 transmits an application information element request for requesting the information element of the application requested by the application information element acquisition request to the distribution server 100. (Step S710). That is, the application information element acquisition unit 314 generates an application information element request to the distribution server 100 in accordance with the application information element acquisition request from the search server 400 and transmits it via the transmission / reception unit 302.

  In response to the application information element request from the mobile terminal 300, the distribution server 100 transmits an application information element response including the information element requested by the application information element request to the mobile terminal 300 (step S712).

  When receiving the application information element response from the distribution server 100, the mobile terminal 300 transmits an application information element acquisition response including the information element included in the application information element response to the search server 400 (step S714).

  The search server 400 receives an application information element acquisition response from the mobile terminal 300. The search server 400 updates the application information by updating the corresponding information element to the information element included in the application information element acquisition response (step S716). That is, the application information element acquisition response from the mobile terminal 300 is input to the application information element update unit 404. The application information element update unit 404 updates the application information by rewriting information elements included in the application information corresponding to the information elements included in the application information element acquisition response. In addition, the search count corresponding to the information element included in the application information element acquisition response is reset to the initial value.

  According to this modification, as in the above-described embodiment, the information element is updated according to the number of times the application is selected as an application to be presented as a result of the search. Accordingly, information is frequently updated as the number of selections increases, that is, as the application is more popular with the user. In addition, for each information element, the update trigger search count is set based on the update frequency, and only the information element that has a search count exceeding the update trigger search count is updated. Therefore, since the frequency with which all information elements are updated at a time can be reduced, an application to be stored in the distribution server 100 and an application to be searched by the search server 400 while suppressing the load on the search server 400. Can be improved.

  In this modification, when the application is updated in the distribution server 100, it is preferable that all information elements related to the application are also updated in the search server 400.

  In the present modification, the search server 400 and the distribution server 100 can be applied even if they are the same device.
