[Broadcast content-related information via short-range wireless communication]
The mobile phone terminal according to the present embodiment is associated with the content according to the execution of the content downloaded and stored in the memory 13 or the content stored in the external memory loaded in the external memory slot. Information is broadcast from the short-range wireless communication unit 17. In the present embodiment, information associated with the content is referred to as content-related information. Note that the user may arbitrarily select whether to set to transmit content-related information or not to transmit the content-related information.

  Here, in the present embodiment, execution of content includes not only execution of an application such as an electronic game but also reproduction of music, video content, ringtone, alarm sound, key operation sound, and the like. In the present embodiment, the content-related information is not the content data itself, but the content name (the name of the music content, the title of the electronic game content, etc.), the name of the content provider providing the content, and the content Genre (category), download source address (URL) when the content is downloaded, sales price of the content, name of the company creating the content, creator name, etc. It is information that is necessary in any case. Note that the content-related information may be only a content ID for uniquely identifying the content. When transmitting the content related information, a terminal ID (for example, a telephone number or an e-mail address of the terminal) that identifies the mobile phone terminal may be added to the content related information and transmitted.

  In the present embodiment, the broadcast transmission of the content related information may be performed, for example, only while the execution of the content is continued, or the start of content execution is set as a time count trigger from the trigger timing. Content-related information is received from another mobile phone terminal until the period elapses, until a certain period elapses from the trigger timing using the end of content execution as a time count trigger, or while content execution continues. The time point at which the transmission request is received may be set as a time count trigger until only a certain period elapses from the trigger timing.

  Note that the broadcast transmission of the content related information is desirably performed intermittently in order to reduce power consumption required for transmission of the content related information.

  In addition, settings for performing broadcast transmission of content-related information from the time when a broadcast transmission request for content-related information is received from another mobile phone terminal until a certain period of time elapses are particularly relevant when content-related information is being continuously executed. Is more effective when the power consumption is lower when the mobile phone terminal on the content-related information transmission side is in a state waiting to receive a content-related information transmission request than when the content-related information transmission side is continuously broadcast.

  In addition, when the content-related information is set to be broadcasted only until the predetermined period elapses with the start of content execution as a trigger timing, the content execution is continued even after the predetermined period elapses. In such a case, the broadcast transmission may be switched until the execution of the content is completed, and the broadcast is performed when the predetermined period has elapsed regardless of whether or not the execution of the content is continued. Transmission may be stopped. Similarly, when the content-related information broadcast transmission is set until the predetermined period elapses with the timing when the content-related information broadcast transmission request is received from another mobile phone terminal as the trigger timing, the constant If the execution of the content continues even after the period has elapsed, the broadcast transmission may be switched until the execution of the content ends, and whether or not the execution of the content is continued. Instead, the broadcast transmission may be stopped when the predetermined period has elapsed.

  On the other hand, even if the content-related information is set to be broadcasted only while the content is being executed, the execution of the content seems to have ended before the predetermined period of time elapses from the trigger timing of the content execution start. In such a case, it is desirable to continue broadcast transmission of content-related information until the predetermined period has elapsed.

  That is, as can be seen from these, in the mobile phone terminal according to the present embodiment, the above-described content execution continues, the content execution starts, the content execution ends, and the content execution continues. In any case after receiving a content-related information transmission request from a mobile phone terminal, broadcast transmission of the content-related information is continued for at least a certain period.

  According to the present embodiment, as described above, by continuing broadcast transmission of content-related information for a certain period or longer, the executed content can be shortened in content execution duration time, for example, as a ring tone. Even if the content is highly specific, it is guaranteed that the content-related information is broadcasted until the predetermined period has elapsed. In other words, at least a certain period of time has passed since the other mobile phone terminal that desires to acquire the content-related information to be broadcast-transmitted starts the execution of the content at the content-related information transmitting side mobile phone terminal. In the period up to, it is possible to acquire the content-related information transmitted by broadcast.

  In the present embodiment, which of these settings is adopted may be arbitrarily selectable by the user, or may be determined in advance in the mobile phone terminal. In addition, the above-described fixed periods may all be the same length period, may be different length periods, or may be set to an arbitrary length by the user.

[Reception of content-related information broadcast by near field communication]
The mobile phone terminal according to the present embodiment has a function of receiving content-related information broadcast by other mobile phone terminals as described above. Then, the mobile phone terminal that has received the content-related information transmitted from the other mobile phone terminal has a function of displaying the acquired content-related information on at least the screen of the display unit 15.

  In addition, the mobile phone terminal according to the present embodiment uses the address included in the content-related information received and acquired as described above, and automatically accesses the content provider site, for example, by an instruction from the user. For example, it may have a function of automatically downloading content data corresponding to information, or downloading in accordance with an instruction from the user.

  Further, when the content-related information received and acquired includes only the content ID that uniquely identifies the content, for example, on the Internet, at least a content ID and a link to a content provider site are associated with each other. It is desirable to have a dedicated site. In this case, the side that has acquired the content related information can acquire the content corresponding to the content ID by accessing the dedicated site and jumping to the content provider site linked to the content ID. It becomes possible. The information associated with the content ID and prepared on the dedicated site includes not only the link information to the content provider but also the same content-related information as described above, such as the content name and content provider name. It is more desirable.

  When the terminal ID of the transmitting mobile phone terminal is added to the received content-related information, the terminal ID may include personal information of the user of the transmitting mobile phone terminal. Therefore, when the content related information is displayed on the screen of the display unit 15, it is desirable not to display the terminal ID. When the content provider is accessed from the mobile phone terminal that has acquired the content-related information including the terminal ID and the content corresponding to the content-related information is purchased, the terminal ID is the content It may be transmitted to the provider. In this case, the content provider that has received the terminal ID may give a merit such as a discount for the next content usage fee or issuance of a coupon to the user of the mobile phone terminal of the terminal ID. As described above, when a user of a mobile phone terminal having a terminal ID is given a merit, it is considered that the user actively uses content and transmits content-related information to the surroundings. In addition, when content-related information is actively transmitted, there is a high possibility that another user who has acquired the content-related information will newly purchase content. There is an advantage that it can be obtained. Similarly, a telecommunications company (mobile phone telecommunications company) can also obtain an advantage of improving profits due to an increase in communication volume.

  Furthermore, even when the terminal ID is not added to the content related information, for example, if a privilege such as discounting the selling price of the content is provided on condition that the content related information is actively transmitted, the content provider Advantages can be given not only to the user but also to the user who purchases the content.

[Sequence of broadcast-side terminal for content-related information]
In FIG. 2, for example, when the execution of content is stopped at least before a certain period of time has elapsed since the start of content execution, broadcast transmission of content-related information is continued until the certain period has elapsed, Sequence diagram on the mobile phone terminal side set to continue broadcast transmission of content-related information until the execution of the content is stopped when the execution of the content continues even after a certain period of time has elapsed since the start of execution Indicates.

  In FIG. 2, the control unit 10 of the mobile phone terminal serving as the content related information transmitting side, for example, a request for starting an electronic game application from the user via the operation unit 14, a request for playing a desired music piece, an incoming call or e-mail When a content execution start request (T1) such as a ringing tone in response to reception or a request for playing an incoming melody is input, the content execution start processing (S1) is performed based on the content execution start request (T1). )I do. Then, the control unit 10 of the mobile phone terminal makes a content-related information notification start request (T2) to the short-range wireless communication unit 17.

  The short-range wireless communication unit 17 that has received the content-related information notification start request (T2) from the control unit 10 performs a content-related information notification start process (S2). At this time, the short-range wireless communication unit 17 performs a process (S3) for starting a timer (hereinafter referred to as a content-related information notification timer) for counting the time of the predetermined period. And the short-range wireless communication part 17 alert | reports content related information to the circumference regularly (intermittently) by broadcast transmission (T3).

  On the other hand, the control unit 10 that has performed the content execution start process (S2), for example, a request to stop the electronic game application from the user via the operation unit 14, a request to stop playback of a desired music piece, end the incoming call, or receive an email When a content execution stop request (T4) such as a ringing tone corresponding to the end or a request to stop the incoming melody is input, the content execution stop processing (S4) is performed based on the content execution stop request (T4). )I do. Then, the control unit 10 makes a content-related information notification stop request (T5) to the short-range wireless communication unit 17.

  The short-range wireless communication unit 17 that has received the content-related information notification stop request (T5) from the control unit 10 determines whether or not to proceed to the content-related information notification end process (S6), which is a subsequent process (S5). )I do. More specifically, the short-range wireless communication unit 17 receives a content-related information notification stop request (T5) from the control unit 10 and the content-related information notification timer has elapsed for the predetermined period or longer. Then, the process proceeds to the content related information notification end process (S6).

  And if it transfers to content related information alerting | reporting completion | finish process (S6), the short-distance radio | wireless communication part 17 will stop the broadcast transmission of the said content relevant information.

[Sequence of receiving terminal of content-related information transmitted by broadcast]
Next, FIG. 3 shows a sequence diagram on the mobile phone terminal side that receives content-related information that is intermittently broadcasted by content-related information notification (T3) as shown in FIG.

  In FIG. 3, when the control unit 10 of the mobile phone terminal serving as the content-related information acquisition request side receives an input (T11) for instructing start of content-related information acquisition from the user via the operation unit 14, for example, the short distance A content-related information reception start request (T12) is made to the wireless communication unit 17. Note that the content related information acquisition start instruction is input, for example, when the user selects a menu item for content related information acquisition start instruction from the menu items displayed on the screen of the display unit 15. .

  The short-range wireless communication unit 17 that has received the content-related information reception start request (T12) from the control unit 10 performs content-related information reception start processing (S11). At this time, the short-range wireless communication unit 17 counts a timer (hereinafter, content-related) for a certain period of time (hereinafter referred to as a reception period) in which the content-related information can be received. A process (S12) for starting an information reception timer) is performed. Here, the reception period counted by the content related information reception timer is based on an intermittent transmission period when content related information is intermittently broadcasted from the mobile phone terminal on the content related information transmission side as described above. Even set at least longer. Accordingly, the short-range wireless communication unit 17 of the mobile phone terminal on the content related information acquisition request side can receive the content related information that is intermittently broadcast by the content related information notification (T3). Become.

  After the content-related information reception start process (S11), the short-range wireless communication unit 17 determines whether or not to move to the content-related information reception end process (S14), which is a subsequent process. That is, in this case, the short-range wireless communication unit 17 proceeds to the content related information reception end process (S13) when the reception period counted by the content related information reception timer elapses.

  When the process proceeds to the content related information reception end process (S14), the short-range wireless communication unit 17 ends the content related information reception process.

  Thereafter, the short-range wireless communication unit 17 notifies the control unit 10 of all content-related information that can be received within the reception period (T13). At this time, content related information may be received from a plurality of mobile phone terminals, or content related information may not be acquired at all.

  Upon receiving the content related information from the short-range wireless communication unit 17, the control unit 10 creates a list of content related information (S15), sends the list to the display unit 15 and displays it on the display screen (T14). As a result, the mobile phone terminal can inform the user of content information executed on other mobile phone terminals around the mobile terminal.

  Further, when displaying the content-related information as a list, a list divided according to the genre of the content (categorized) may be displayed, or only a list of genres desired by the user may be displayed. . The genre classification of the list and the user-desired list display are performed, for example, by the user selecting a menu item for designating the list division from among the menu items displayed on the screen of the display unit 15. .

[Transmission / reception of content-related information specifying the other party via short-range wireless communication]
In the above description, an example in which content-related information is broadcast-transmitted has been given. However, the mobile phone terminal of the present embodiment transmits in response to a request from another mobile phone terminal or the like that desires to acquire the content-related information (that is, It is also possible to perform transmission in a state where the other party is specified. In particular, this example is effective when the power consumption is lower when the mobile phone terminal on the content related information transmission side is in a state waiting for reception of a content related information transmission request than when content related information is broadcasted as described above. It is.

  Here, in the case where the content related information is transmitted in a state in which the other party is specified, the mobile phone terminal serving as the content related information transmitting side is allowed to receive another mobile phone only while the execution of the content is continued. The terminal may be in a state waiting for receiving a content-related information transmission request from the terminal. The content execution start is triggered by a time count as a trigger for the time count until a certain period elapses from the trigger timing, or the content execution end As a trigger, it may be in a state of waiting for receiving a content-related information transmission request from another mobile phone terminal only until a certain period elapses from the trigger timing.

  Further, in the present embodiment, when the content-related information transmission request reception waiting state from another mobile phone terminal is set only for a certain period after the start of content execution, If the mobile phone terminal on the information transmission side continues to execute the content even after the predetermined period has elapsed, it transmits content-related information from other mobile phone terminals until the execution of the content ends. It may be switched to continue the request reception waiting state, and a content related information transmission request from another mobile phone terminal when the above-mentioned fixed period has passed, regardless of whether or not the execution of the content is continued. The reception waiting state may be stopped.

  On the other hand, even if the content-related information transmission request reception waiting state from another mobile phone terminal is set to continue only while content execution is continued, the mobile phone terminal serving as the content-related information transmission side is, for example, If execution of the content ends before a certain period of time elapses from the start of content execution, the content related information transmission request reception waiting state from another mobile phone terminal is continued until the certain period elapses. Is desirable.

  That is, as can be seen from the above, in the mobile phone terminal of the present embodiment, the content-related information transmission request reception waiting state from another mobile phone terminal is continued for at least a certain period.

  According to the present embodiment, as described above, the content-related information transmission request reception waiting state from another mobile phone terminal is continued for at least a certain period, so that the executed content is like a ring tone, for example. Even if the content execution duration is likely to be short, content-related information transmission requests from other mobile phone terminals can be received until the predetermined period has elapsed. That is, in other words, the other mobile phone terminal that desires to acquire the content-related information that is broadcast-transmitted passes a certain period of time after the execution of the content is started at the content-related information transmitting side mobile phone terminal. Until the content related information transmission request, the content related information transmission request can be sent to the mobile phone terminal on the content related information transmission side, and the content related information broadcasted after the content related information transmission request is acquired. It becomes possible to do.
