(Schematic configuration of mobile communication system)
FIG. 1 is a schematic configuration diagram of a mobile radio communication system 1 including a radio communication terminal according to the present embodiment. As shown in FIG. 1, a mobile radio communication system 1 includes a radio communication terminal 100, a BCMCS server 200, a network 300, a PDSN (Packet Data Serving Node) 400, and a PCF (PCF: Packet Control Function) 500. , AN (Access Network) 600.

  The mobile radio communication system 1 is a mobile communication system compatible with 1xEV-DO. In the mobile radio communication system 1, data transmission / reception (unicast) is performed by bidirectional communication of data using channels individually assigned to the radio communication terminal 100.

  The mobile radio communication system 1 also supports a BCMCS (Broadcast Multicast Service) function that can simultaneously deliver the same data to a plurality of radio communication terminals 100. In the BCMCS function, one-way communication data distribution (broadcast / multicast) is performed using a channel capable of distributing data to a plurality of unspecified or designated wireless communication terminals 100 simultaneously.

  In addition, the mobile radio communication system 1 provides a content distribution service using the BCMCS function. In such a content distribution service, the wireless communication terminal 100 selects in advance content to be distributed among the content distributed by the BCMCS server 200. When the distribution time of each content comes, the BCMCS server 200 distributes all of the wireless communication terminals 100 registered to distribute the content all at once. The wireless communication terminal 100 automatically receives the content via the network 300, the PDSN 400, the PCF 500, and the AN 600 when the distribution time of the selected content comes.

  Note that the numbers of the radio communication terminals 100, PDSN 400, PCF 500, and AN 600 included in the mobile radio communication system 1 are not limited to the quantities shown in FIG.

(Function block configuration of wireless communication terminal)
With reference to FIG. 2, the functional block configuration of the radio communication terminal 100 constituting the mobile radio communication system 1 will be described.

  Hereinafter, portions related to the present invention will be mainly described. Therefore, it should be noted that the radio communication terminal 100 may include a functional block that is essential for realizing the function as the device and that is not illustrated or omitted.

  As illustrated in FIG. 2, the wireless communication terminal 100 includes a transmission / reception unit 110, a content distribution registration processing unit 120, a remaining battery level detection unit 130, a time shift processing unit 140, an on-demand processing unit 150, and a battery 160. A storage unit 170, a display unit 180, and an operation unit 190.

  The transmission / reception unit 110 automatically receives the registered content distributed from the BCMCS server 200 at the distribution time of the content (hereinafter, registered content) for which distribution registration setting has been performed in the content distribution registration processing unit 120 described later.

  In addition, the transmission / reception unit 110 automatically receives the content to be distributed based on information necessary for automatically receiving the content stored in the storage unit 170.

The content distribution registration processing unit 120 performs content distribution registration with the BCMCS server 200 and performs reception settings. Specifically, the content distribution registration processing unit 120 includes a list of content distributed from the BCMCS server 200, and the like. The content desired to be distributed is selected by operating the operation unit 190, and the content is registered for distribution.

  Here, content distribution registration means that the content distribution registration processing unit 120 notifies the BCMCS server 200 of information necessary for distributing the selected content (for example, identification information of the wireless communication terminal 100). Distribution information (hereinafter referred to as registered content information) necessary for receiving the content selected from the above is acquired, and reception setting is performed based on the distribution information. Hereinafter, the content registered for distribution is referred to as “registered content”.

  Here, as shown in FIG. 3, the registered content information is information including a content ID, a content name, a scheduled delivery date, retransmission information, and whether manual retry is possible.

  The scheduled delivery date is the scheduled delivery time of the registered content. The retransmission information is information for determining whether or not the registered content is redistributed. The manual retry availability is information for determining whether or not on-demand reception described later is possible.

  The remaining battery level detection unit 130 detects the remaining battery level of the battery 160. Further, when the registered content is distributed, the remaining battery level detection unit 130 notifies the time shift processing unit 140 and the on-demand processing unit 150 of the detected remaining battery level.

  When the registered content is distributed, the time shift processing unit 140 determines whether or not the registered content is redistributed if the remaining battery level notified by the remaining battery level detection unit 130 is equal to or less than a threshold value. . When the registered content is redistributed, the time shift processing unit 140 cancels reception of the registered content, and receives the registered content when the registered content is redistributed.

  Specifically, the time shift processing unit 140 refers to “retransmission information” included in the registered content information acquired by the content distribution registration processing unit 120 and determines whether or not the registered content is redistributed. When the retransmission information is “with retransmission”, the registered content is redistributed and can be received at the time of redistribution, so the time shift processing unit 140 cancels reception of the registered content.

  For example, as shown in FIG. 4, the registered content (for example, content A) is distributed at 12:00, but is redistributed at 18:00 because the above-described retransmission information is “with retransmission”. Therefore, the time shift processing unit 140 cancels reception of the content A when the remaining battery level is equal to or less than the threshold value at 12:00, and receives the content A when redistributed at 18:00.

  Further, the time shift processing unit 140 may control to display the redistribution time of the registered content on the screen of the display unit 180 of the wireless communication terminal 100.

  Specifically, as shown in FIG. 5A, when the reception of the registered content (for example, content A) is canceled, the time shift processing unit 140 sets the redistribution time of content A (next time 18:00). You may display on the screen of the display part 180 of the wireless communication terminal 100, and you may notify a user.

  In addition, when the registered content is not redistributed, the time shift processing unit 140 notifies the registered content delivery time, causes the user to determine whether to receive the registered content, and based on the user's operation. It may be determined whether or not to receive the registered content. Further, when receiving the registered content in the middle of reception, the time shift processing unit 140 may notify (warn) the user that the battery may be exhausted (run out).

  Specifically, as shown in FIG. 5B, when the registered content is not redistributed, the time shift processing unit 140 is in the middle of receiving when the registered content is received in order to cause the user to determine to receive the registered content. The user may be notified (warned) by displaying on the screen of the display unit 180 of the wireless communication terminal 100 that the battery may be exhausted (run out).

  On the other hand, since the battery may be exhausted (run out), when the user determines not to receive the registered content, the fact that the registered content has not been received is displayed on the screen of the display unit 180 of the wireless communication terminal 100. It may be displayed and notified to the user.

  When the registered content is distributed, the on-demand processing unit 150 requests acquisition of the registered content when the remaining battery level notified by the remaining battery level detection unit 130 is equal to or less than the threshold and the reception of the registered content is canceled. Then, the registered content is received using the communication path set in response to the request. In addition, the on-demand processing unit 150 may request acquisition of registered content when it is detected that the battery has been charged after canceling reception of the registered content (when the remaining battery level is greater than a threshold).

  Specifically, the on-demand processing unit 150 refers to “manual retry possibility” included in the registered content information acquired by the content distribution registration processing unit 120 and determines whether or not on-demand reception is possible. When the manual retry is permitted, the on-demand reception of the registered content is possible. Therefore, when the reception of the registered content is canceled based on the remaining battery level of the battery 160, the on-demand processing unit 150 Then, a request is made to a server (for example, the BCMCS server 200) on the network storing the distribution content, and the content is acquired.

  Here, on-demand reception means that, as shown in FIG. 6, after the distribution time has elapsed, the wireless communication terminal 100 actively requests acquisition of registered content, and in response to the request, the wireless communication terminal 100 is requested. The registered content is received from the BCMCS server 200 using the set communication path (unicast). That is, the wireless communication terminal 100 receives the registered content using unicast instead of broadcast / multicast used for normal distribution so as not to affect the distribution of other content.

  Further, as shown in FIG. 7A, when the on-demand processing unit 150 cancels reception of the registered content (for example, content A), wireless communication indicates that the content A can be received on-demand (for example, the DOWNLOAD button). You may display on the screen of the display part 180 of the terminal 100, and may notify a user. At this time, the on-demand processing unit 150 may display a link to the content A (for example, the DOWNLOAD button) on the screen of the display unit 180 of the wireless communication terminal 100.

  Furthermore, when the on-demand processing unit 150 detects that the battery is charged after canceling reception of the registered content (for example, the remaining battery level of the battery 160 detected by the remaining battery level detection unit 130 is greater than the threshold value). In other words, on-demand reception and a link to the registered content whose reception has been canceled may be displayed on the screen of the display unit 180 of the wireless communication terminal 100.

  In addition, when the on-demand processing unit 150 cannot receive on-demand (for example, when manual retry is possible or not), the on-demand processing unit 150 notifies the registered content delivery time, and determines whether or not to receive the registered content. The user may determine whether or not to receive the registered content based on the user's operation. Further, the on-demand processing unit 150 may notify the user that the battery may be consumed (run out) when receiving the registered content.

  Specifically, as shown in FIG. 7B, since the on-demand processing unit 150 cannot receive on-demand, when the user determines to receive the registered content, the battery is consumed when the registered content is received. It may be displayed on the screen of the display unit 180 of the wireless communication terminal 100 to notify the user that there is a risk of being exhausted.

  On the other hand, if the user decides not to receive the registered content because the battery may be exhausted (runs out), the fact that the registered content has not been received is displayed on the screen of the wireless communication terminal 100, and the user May be notified.

  The content distribution registration processing unit 120, the battery remaining amount detection unit 130, the time shift processing unit 140, and the on-demand processing unit 150 function as a control unit that performs processing by the CPU or the like based on a program stored in the storage unit 170. You may comprise as a block.

  That is, when the control unit automatically receives the content based on the distribution time included in the information necessary for automatically receiving the content, the remaining battery level detected by the remaining battery level detection unit 130 (detection unit) is equal to or less than the threshold value. In this case, the reception of the content at the distribution time may be canceled and the control unit may function to control to receive the content when the content is redistributed based on the redistribution information included in the information.

  In addition, when the control unit automatically receives the content based on the distribution time included in the information necessary for automatically receiving the content, the remaining battery level detected by the remaining battery level detection unit 130 (detection unit) is equal to or less than the threshold value. In this case, it may function as a control means for canceling reception of distribution content at the distribution time, requesting a server storing the content to transmit the content, and acquiring the content by unicast.

  The storage unit 170 stores various programs, received content, and the like. Furthermore, the storage unit 170 stores information necessary for automatically receiving content distributed via a channel of the mobile wireless communication system 1 (wireless communication system) at a predetermined distribution time.

  In step S220, the radio communication terminal 100 determines whether the remaining battery level is equal to or less than a threshold value. If the remaining battery level is greater than the threshold (NO in step S220), the operation proceeds to step S290, and the wireless communication terminal 100 automatically receives the registered content distributed from the BCMCS server. When the remaining battery level is equal to or less than the threshold (YES in step S220), the operation proceeds to step S230.

  In step S230, the wireless communication terminal 100 determines whether or not the registered content is redistributed. When the registered content is redistributed (YES in step S230), the operation proceeds to step S240, and the wireless communication terminal 100 displays the redistribution time on the screen of the wireless communication terminal 100 and notifies the user (FIG. 5). (See (a)). If the registered content is not redistributed (NO in step S230), the operation proceeds to step S250.

  In step S250, the wireless communication terminal 100 notifies the user that it is the delivery time of the registered content.

  In step S260, the wireless communication terminal 100 causes the user to determine whether to receive registered content. At this time, the wireless communication terminal 100 displays on the screen of the wireless communication terminal 100 that the battery may be consumed (runs out) when receiving the registered content, and notifies (warns) the user (FIG. 5 ( b)).

  When the user determines to receive the registered content, the operation proceeds to step S290, and the wireless communication terminal 100 receives the registered content distributed from the BCMCS server. When it is determined that the user does not receive the registered content, the operation proceeds to step S270. In step S270, the wireless communication terminal 100 displays that there is unreceived content on the screen of the wireless communication terminal 100, and prompts the user. Notice.

  In step S280, the wireless communication terminal 100 displays on the screen of the wireless communication terminal 100 that the on-demand reception is possible and a link to the registered content whose reception has been canceled (see FIG. 7A). Step S280 may be performed when the wireless communication terminal 100 detects that the battery is charged.
