The control unit 16 causes the content stored in the memory 15 to be output from the display unit 12 or the speaker 13.

  According to the present embodiment, the following effects can be obtained.

  The first function and effect are as follows.

  The push server 2 generates a content list and an update notification based on the preference data transmitted from the mobile phone 1. For this reason, the user can obtain the list and the update notification with one preference data registration. Therefore, the user does not need to perform an operation for registering the preference data for list and an operation for registering the preference data for update notification, and the user's operation can be simplified.

  The second effect is as follows.

  The update notification generation unit 25d generates a content update list corresponding to only the content information changed by the search information changing unit 25c as the content update notification. For this reason, when the user selects a desired content from the content list or the content update list, the user has only to select the desired content from the list, which improves the usability of the user. Further, since the content update list corresponding to only the changed content information is provided, it is possible to reduce the capacity of the content update notification.

  The third effect is as follows.

  The CP server 3 stores an outline of content, and the list generation unit 25a generates a content list including an outline request for requesting the CP server 3 to obtain an outline of content according to preference data. For this reason, the user can easily obtain an outline of the content.

  The fourth function and effect are as follows.

  The cellular phone 1 receives an output unit (display unit 12 or speaker 13), a communication unit 14 that receives an outline of the content transmitted from the CP server 3, and an outline of the content when the communication unit 14 receives the outline of the content. Is output from the output unit (display unit 12 or speaker 13), and thereafter the control unit 16 that deletes the outline of the content is included.

  For this reason, it becomes possible to prevent the outline of the content from remaining permanently in the mobile phone 1. For this reason, for example, the outline of the content can be made a trial version (for example, for trial listening).

  The fifth effect is as follows.

  The list generation unit 25a generates a content list in a format corresponding to the type of content. For this reason, according to the kind of content, it becomes possible to make a content list into a format which a user can see easily.

  Note that this embodiment may be modified as follows.

  For example, when the communication unit 14 receives the content update notification, the control unit 16 causes the display unit 12 to execute display processing for displaying the received content update notification in combination with the content list stored in the memory 15. May be.

  In this case, the user can search for desired content in consideration of the content update notification and the content list. In addition, when the user selects the desired content, it is only necessary to perform one type of work of selecting the desired content from the list, which improves the usability of the user.

  Further, the update notification generation unit 25d searches the search DB 22 whose content information has been changed by the search information change unit 25c for content information corresponding to the preference data stored in the storage unit 23, and displays the search result. A corresponding content update list may be generated as a content update notification. In this case, the content update list generated by the update notification generation unit 25d includes information about content that has not been updated.

  For this reason, even if the mobile phone 1 does not have a function of displaying the content update notification in combination with the content list, the user can select a desired content from the list showing all the content according to the preference data. It becomes possible to search.

  When the search DB 22 also stores content itself, the update notification generation unit 25d may use the changed content itself as the content update notification. In this case, since the content is provided as a content update notification, for example, the user does not have to perform the operation of selecting the desired content from the content update list and obtaining the selected desired content. Improves.

  Furthermore, it is desirable that the present embodiment includes the following examples.

When is selected, the CP server 3 may transmit the content requested by the mobile phone 1 to the mobile phone 1 by e-mail.

  The summary request shown in the content list and the content update list is a summary request for requesting the CP server 3 to send the summary of the content requested by the mobile phone 1 to the mobile phone 1 by e-mail. When the overview request is selected, the CP server 3 may transmit an overview of the content requested by the mobile phone 1 to the mobile phone 1 by e-mail.

  Further, when there are a plurality of CP servers 3, the mobile phone 1 may obtain content from the plurality of CP servers 3. If the content download method differs between the plurality of CP servers 3, if the push server 2 unifies the download method between the plurality of CP servers 3, the mobile phone 1 is unified by the push server 2. The content can be obtained from a plurality of CP servers 3 by the download method.

  The content stored in the CP server 3 is not limited to the above, and can be changed as appropriate. For example, the CP server 3 may store content related to the store. Specifically, the CP server 3 may store a store map or store coupon as content.

  One CP server 3 may have the function of the push server 2.

  Further, the input unit 11 may accept text-style preference data input by the user. The input unit 11 may accept the preference data in a code (for example, a two-dimensional barcode or a one-dimensional barcode).

  In addition, the input unit 11 may accept preference data selected by the user from preference data candidates registered in advance in the mobile phone 1.

  In this case, preference data candidates may be shown in stages like a tree structure.

  For example, the preference data candidates are divided into higher preference data candidates, middle preference data candidates, and lower preference data candidates. First, the user selects a desired preference data candidate from the higher preference data candidates, and then The desired preference data candidate is selected from the middle preference data candidates corresponding to the selected higher preference data candidate, and then the desired preference data candidate corresponding to the selected middle preference data candidate is selected. Select preference data. The input unit 11 receives, as preference data, the upper preference data candidate, the middle preference data candidate, and the lower preference data candidate selected by the user.

  In this embodiment, the list generation unit 25a, the change recognition unit 25b, the search information change unit 25c, and the update notification generation unit 25d are grouped in the control unit 25, but the list generation unit 25a The change recognition unit 25b, the search information change unit 25c, and the update notification generation unit 25d may be separately provided.

  According to the present embodiment, the following effects can be obtained.

  It becomes possible to easily obtain the content desired by the user. The reason is that the user can obtain the desired content based on the content list generated by the list generation unit 25a and the content update notification generated by the update notification generation unit 25d.

  The user can save a packet fee. This is because the desired content can be easily obtained, and the number of packets required to search for the content can be reduced.
