BEST MODE FOR CARRYING OUT THE INVENTION

[Schematic configuration of mobile communication system]

FIG. 2 is a schematic configuration diagram of the mobile radio communication system 1 including the radio communication terminal according to the present embodiment. As shown in FIG. 2, the 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, a PCF (Packet Control Function) 500, and AN. (Access Network) 600

[0028] The mobile radio communication system 1 is a mobile communication system compatible with lxEV-DO. In the mobile radio communication system 1, data transmission / reception (cast) is performed by channels individually assigned to the radio communication terminal 100.

[0029] Mobile radio communication system 1 also supports a BCMCS (Broadcast Multicast Service) function that can simultaneously distribute the same data to a plurality of radio communication terminals 100. In the BCMCS function, 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.

[0030] In addition, the mobile radio communication system 1 provides a content distribution service using a powerful BCMCS function. In such a content distribution service, the wireless communication terminal 100 selects in advance the content desired to be distributed from the content distributed by the BCMCS server 200. The BCMCS server 200 distributes the contents all at once to all the wireless communication terminals 100 that have registered the distribution of contents at the distribution time of each content. The wireless communication terminal 100 automatically receives the content via the tag 300, the PDSN 400, the PCF 500, and the AN 600 when the delivery time of the selected content comes.

[0031] Radio communication terminal 100, PDSN400, PC included in mobile radio communication system 1

The quantity of F500 and AN600 is not limited to the quantity shown in Figure 2.

[0032] (Functional block configuration of wireless communication terminal) With reference to FIG. 3, the functional block configuration of radio communication terminal 100 constituting mobile radio communication system 1 will be described.

[0033] In the following, 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 not shown or a description that is not necessary for realizing the function as the device.

As shown in FIG. 3, radio communication terminal 100 includes transmission / reception unit 110, content distribution registration processing unit 120, remaining battery level detection unit 130, time shift processing unit 140, and on-demand processing unit.

150, a battery 160, a storage unit 170, a display unit 180, and an operation unit 190.

[0035] The transmission / reception unit 110 automatically receives the registered content that is also distributed by 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. To do.

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

[0037] The content distribution registration processing unit 120 performs content distribution registration with the BCMCS server 200 and performs reception settings.

[0038] Specifically, the content distribution registration processing unit 120 selects the content desired to be distributed from the list of content distributed from the BCMCS server 200 by operating the operation unit 190, and registers the distribution of the content. Do.

[0039] Specifically, 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).

Then, distribution information (hereinafter referred to as registered content information) necessary for receiving the selected content is acquired from the BCMCS server 200, and reception setting is performed based on the distribution information. Hereinafter, the content registered for distribution is referred to as “registered content”.

[0040] Here, the registered content information includes a content ID, a content name, as shown in FIG.

Information including the scheduled delivery date, retransmission information, and whether manual retry is possible.

[0041] The scheduled delivery date and time 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 detecting unit 130 notifies the time shift processing unit 140 and the on-demand processing unit 150 of the detected remaining battery level.

[0043] When the registered content is distributed, the time shift processing unit 140 determines whether 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 the threshold value. Determine whether or not. 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. judge. 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.

[0045] For example, as shown in FIG. 5, the registered content (for example, content A) is delivered at 12:00. Since the retransmission information described above is "with retransmission", it is also re-delivered at 18:00. The 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 at 12:00, and receives the content A when redistributed at 18:00.

[0046] 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. 6 (a), when the time shift processing unit 140 cancels reception of the registered content (for example, content A), the redistribution time of content A (next time 18). : 0 0) may be displayed on the screen of the display unit 180 of the wireless communication terminal 100 to notify the user.

[0048] Also, if the registered content is not redistributed, the time shift processing unit 140 notifies that it is the distribution time of the registered content, and determines whether or not to accept the registered content to the user. It is also possible to determine whether or not the user has the ability to receive the registered content based on the user's operation. 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. 6 (b), the time shift processing unit 140 receives the registered content in order to make the user decide to receive the registered content when the registered content is not redistributed. Then, it may be displayed on the screen of the display unit 180 of the wireless communication terminal 100 to notify the user (warning) that the battery may be exhausted (run out) during reception.

[0050] On the other hand, when the user decides not to receive the registered content because the battery may be exhausted (runs out), the wireless communication terminal 100 confirms that the registered content has not been received. It may be displayed on the screen of the display unit 180 to notify the user.

[0051] When the registered content is distributed, the on-demand processing unit 150 determines that if the remaining battery level notified by the remaining battery level detection unit 130 is equal to or less than the threshold value and cancels reception of the registered content, To receive the registered content 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 registered content (when the remaining battery level becomes greater than the threshold). .

[0052] Specifically, the on-demand processing unit 150 refers to "whether or not manual retry is possible" included in the registered content information acquired by the content distribution registration processing unit 120, and determines whether or not the on-demand reception is possible. judge. When manual retry is enabled, the on-demand reception of the registered content is possible. Therefore, if reception of the registered content is canceled based on the battery level of the Notary 160, the on-demand processing unit 150 makes a request to a sano (for example, BCMCS server 200) on the network storing the distribution content, and obtains the content.

Here, on-demand reception means that, as shown in FIG. 7, the wireless communication terminal 100 actively requests acquisition of registered content after the distribution time has elapsed, and the wireless communication terminal responds to the request. The registered content is received from the BCMCS server 200 using the communication path (cast) set for 100. That is, the wireless communication terminal 100 receives registered content by using multicast in the broadcast Z multicast used for normal delivery so as not to affect the delivery of other content.

[0054] Also, as shown in FIG. 8 (a), the on-demand processing unit 150 performs registration content (for example, When the reception of the content A) is canceled, the fact that the content A can be received on demand (for example, the DOWNLOAD button) may be displayed on the screen of the display unit 180 of the wireless communication terminal 100 to notify the user. At this time, the on-demand processing unit 150 may display a link (for example, a DOWNLOAD button) to the content A on the screen of the display unit 180 of the wireless communication terminal 100.

[0055] 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). If the value is larger than the threshold value), on-demand reception and a link to the registered content for which reception has been canceled may be displayed on the screen of display unit 180 of wireless communication terminal 100.

In addition, if the on-demand processing unit 150 cannot receive on-demand (for example, if the manual retry availability S is “No”), the on-demand processing unit 150 notifies the registered content delivery time, and The user may determine whether or not to receive the registered content, and determine whether or not the user can receive the registered content based on the user's operation. Further, when the on-demand processing unit 150 receives the registered content, the on-demand processing unit 150 may notify the user that the battery may be exhausted (run out).

Specifically, as shown in FIG. 8 (b), the on-demand processing unit 150 cannot receive on-demand, and therefore receives a registration content when the user determines to receive registration content. Then, the user may be notified by displaying on the screen of the display unit 180 of the wireless communication terminal 100 that the battery may be exhausted.

[0058] On the other hand, when the user decides not to receive the registered content because the battery may be exhausted (runs out), the wireless communication terminal 100 indicates that the registered content has not been received. You may display on a screen and notify a user.

[0059] The content distribution registration processing unit 120, the remaining battery level detection unit 130, the time shift processing unit 140, and the on-demand processing unit 150 are processed by a CPU or the like based on a program stored in the storage unit 170. It may be configured as a functional block of the control unit.

[0060] That is, when the content is automatically received based on the delivery time included in the information necessary for automatically receiving the content, the control unit detects the remaining battery level detection unit 130 (detection unit). When the remaining battery level is equal to or less than the threshold, the control is performed to cancel the reception of the content at the distribution time and to receive the content when the content is redistributed based on the redistribution information included in the information It may function as a part.

[0061] In addition, the control unit detects when the content is automatically received based on the distribution time included in the information necessary for automatically receiving the content! If the remaining battery level is less than or equal to the threshold, reception of the distribution content at the distribution time is canceled, and the server storing the content is requested to transmit the content and controlled to be obtained by duplex It may function as a control unit.

[0062] 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.

[0063] (Operation of mobile communication system and wireless communication terminal)

Next, the operation of radio communication terminal 100 included in mobile radio communication system 1 will be described.

[0064] (1) Content distribution registration operation

FIG. 9 shows an operation of registering with the distribution service (BCMCS server 200) in order to acquire the content of the wireless communication terminal 100 (content distribution registration processing unit 120).

In step S110, radio communication terminal 100 selects content desired to be distributed from a list of content distributed from BCMCS server 200 or the like.

[0066] In step S120, the BCMCS server 200 prepares for content distribution registration.

[0067] In step S130, the BCMCS server 200 requests the wireless communication terminal 100 to confirm content distribution registration.

In step S 140, wireless communication terminal 100 transmits content distribution registration confirmation (acceptance) to BCMCS server 200.

[0069] In step S150, the BCMCS server 200 transmits the above-described registered content information to the radio communication terminal 100. [0070] In step S160, the BCMCS server 200 performs distribution registration so that the selected content is distributed to the wireless communication terminal 100 at the time of distribution.

In step S170, the BCMCS server 200 transmits a distribution registration completion notification to the wireless communication terminal 100.

[0072] Then, radio communication terminal 100 performs content reception setting for the distribution service by performing the above steps.

[0073] (2) Content reception operation

FIG. 10 shows an operation in which the wireless communication terminal 100 receives registered content. Here, an example will be described in which wireless communication terminal 100 receives registered content by combining time shift processing section 140 and on-demand processing section 150 described above.

[0074] In step S210, the distribution time of the registered content is reached.

In step S220, radio communication terminal 100 determines whether or not 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. In step S290, the wireless communication terminal 100 automatically receives the registered content to which the BCMCS server power is also distributed. If the remaining battery level is below the threshold (YES in step S220), the operation proceeds to step S230.

[0076] In step S230, the wireless communication terminal 100 determines whether or not the registered content is redistributed. If the registered content is redistributed (YES in step S230), the operation proceeds to step S240. In step S240, the wireless communication terminal 100 displays the redistribution time on the screen of the wireless communication terminal 100 and notifies the user (see FIG. 6 (a)). If the registered content is not redistributed (NO in step S230), the operation proceeds to step S250.

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

[0078] In step S260, wireless communication terminal 100 causes the user to determine whether or not 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. 6). (See (b)). [0079] If it is determined that the user receives the registered content, the operation proceeds to step S290. In step S290, wireless communication terminal 100 receives the registered content distributed from the BCMCS server. If 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 on the screen of the wireless communication terminal 100 that there is unreceived content and notifies the user.

[0080] 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 (FIG. 8 (a)). reference). Step S280 may be performed when the wireless communication terminal 100 detects that the battery is charged.

[0081] (Action 'effect)

According to the mobile wireless communication system 1 according to the present embodiment, when the registered content is distributed, if the remaining battery level of the wireless communication terminal 100 is equal to or less than the threshold, the reception of the registered content is canceled, thereby canceling the wireless communication terminal 100. It is possible to prevent the battery of the communication terminal 100 from being exhausted. That is, even if the wireless communication terminal 100 does not stop the automatic reception of the registered content (even if the content distribution service is not turned off (cancel registration)), it is possible to prevent the battery from being exhausted.

[0082] Further, since the registered content can be received when the registered content is redistributed, the opportunity to acquire the registered content can be prevented from being lost.

[0083] According to the mobile radio communication system 1 according to the present embodiment, by notifying the redistribution time of the registered content, the user charges the battery of the radio communication terminal 100 by the redistribution time. The registered content can be acquired at the time of redistribution.

[0084] According to the mobile radio communication system 1 according to the present embodiment, when the registered content is received, the user is notified that the battery may be exhausted, so that the user should receive the registered content. It is possible to appropriately determine whether or not

[0085] According to the mobile radio communication system 1 according to the present embodiment, when the registered content is redistributed, the radio communication terminal 100 does not receive the registered content. , Because it can actively request the acquisition of the content You can make sure that you don't lose the opportunity to get content.

[0086] Further, since wireless communication terminal 100 can receive registered content by multicast (using a communication path set in response to a request for acquiring registered content), it can distribute other content. Even at the time, it is possible to receive registered content that does not affect the delivery of other content via broadcast z multicast.
