  The mobile terminal device 1-1 includes a mobile phone network communication processing unit 40-1, a wireless LAN communication processing unit 41-1, and a Bluetooth communication processing unit 42-1. Among these, the mobile phone network communication processing unit 40-1 and the wireless LAN communication processing unit 41-1 are realized by the communication control unit 11-1 and the wireless unit 12-1, respectively. Also, the Bluetooth communication processing unit 42-1 is realized by the Bluetooth communication unit 36. The same applies to the portable terminal device 1-2.

To do.

  Here, the terminal device capability information includes the remaining amount of the battery 29-1 (FIG. 2) (unit: mAh (milliampere hour)). The remaining amount of the battery 29-1 can be obtained using a known technique. In one example, a lookup table for associating the voltage value between the terminals of the battery 29-1 and the remaining amount is prepared. The terminal device capability information transmission unit 100-1 measures the voltage value between the terminals of the battery 29-1, and acquires the remaining amount of the battery 29-1 by referring to the lookup table. When the mobile terminal device 1-1 is driven by an AC power source, the terminal device capability information transmission unit 100-1 displays information indicating that in place of the remaining amount of the battery 29-1, in the terminal device capability information. Include in

  The terminal device capability information includes communication connection means information indicating one or more communication connection means used by the mobile terminal device 1-1. Here, since the mobile terminal device 1-1 can use three communication connection means (mobile phone network, wireless LAN, and Bluetooth), the communication connection means information is information indicating these three communication connection means.

  The content transmission / reception unit 103-1 transmits / receives content to / from the content transmission / reception unit 103-2. Details of this transmission / reception will be described in the description of the content transmission / reception unit 103-2.

  The terminal device capability information receiving unit 101-2 functions as a terminal device capability information receiving unit that receives the terminal device capability information (such as the remaining amount of the battery 29-1) from the mobile terminal device 1-1. The main control unit 10 takes out the remaining amount of the battery 29-1 from the received terminal device capability information, and stores it in the connected terminal power status table of the storage unit 43. When the received terminal device capability information includes information indicating that it is driven by an AC power source, the main control unit 10 stores the information in the connected terminal power status table of the storage unit 43. Let

  At this stage, the main control unit 10 displays on the main display unit 20 an icon indicating the received remaining amount of the battery 29-1 or information indicating that the mobile terminal device 1-1 is driven by the AC power source. It may be displayed. In this way, the user of the mobile terminal device 1-2 can know at a glance the approximate remaining amount of the battery 29-1.

  Further, in addition to the icon, the main control unit 10 also displays an icon indicating the remaining amount of the battery 29-2 or information indicating that the mobile terminal device 1-2 is driven by the AC power source on the main display unit 20. It is also possible to make it. In this case, it is desirable that the display of each icon be unified so that the comparison is easy (remaining display time, display with a battery mark, voltage, etc.). In addition, when there are a plurality of mobile terminal devices 1 as communication partners, it is desirable to write an icon for each mobile terminal device 1 together.

Also, the terminal device capability information receiving unit 101-2 extracts the communication connection means information from the received terminal device capability information and outputs it to the communication connection means determination unit 102-2.
The communication connection means determination unit 102-2 communicates with the mobile terminal apparatus 1-1 based on the input communication connection means information and one or more communication connection means used by the mobile terminal apparatus 1-2. It functions as a communication connection means determination means for determining one or a plurality of communication connection means that can be used for connection. Here, since both the mobile terminal device 1-1 and the mobile terminal device 1-2 can use a mobile phone network, a wireless LAN, and Bluetooth, the communication connection means determination unit 102-2 determines these as the mobile terminal device 1- 1 or a plurality of communication connection means that can be used for communication connection with 1. The communication connection means determination unit 102-2 stores information indicating the one or more communication connection means determined in this way in the communication connection means table.

  It is preferable that the main control unit 10-2 actually starts communication connection for one or a plurality of communication connection units determined to be usable by the communication connection unit determination unit 102-2. In this way, when the content transmission / reception unit 103-2 tries to transmit / receive content as described later, any communication connection means can be used without negotiation for starting communication connection. Become.

  Next, the main control unit 10-2 receives a display operation of the content list screen by the user via the operation unit 14-2 (FIG. 2), and is a list of contents stored in the storage unit 43-2. A content list screen is displayed on the main display unit 20.

  When displaying the content stored in the directory structure, the main control unit 10-2 displays a list of thumbnail images of the content in a specific directory, and when there is a lower directory of the directory, the lower directory A thumbnail image indicating the above (the directory image) is also displayed as a list.

  Furthermore, the main control unit 10-2 also displays a list of contents to be received in response to a user operation. In this case, the main control unit 10-2 receives a list of contents from the mobile terminal device 1-1, and displays a list of thumbnail images of the contents included in the list. The thumbnail image in this case is preferably a predetermined image indicating that the content is to be received.

  FIG. 4 is an example of a content list screen displayed by the main display unit 20. In the example shown in the figure, the display screen of the main display unit 20 includes a pictogram area D1 and a determination result presentation area D2. Each thumbnail image is displayed in the pictogram area D1, and can be pointed and selected by a user operation. Processing when a specific thumbnail image is pointed by a user operation (when the cursor is placed on the specific thumbnail image) will be described later. When a specific thumbnail image is selected by a user operation, the content transmission / reception unit 103-2 starts content transmission / reception processing for the selected thumbnail image with the content transmission / reception unit 103-1. The determination result presentation area D2 will be described later.

  Returning to FIG. The calculation unit 160-2 calculates the content capacity that can be transmitted / received by the mobile terminal device 1-1 based on the remaining amount of the battery 29-1 stored in the connected terminal power status table. Thereby, the calculation part 160-2 functions as a calculation means. Specifically, for each communication connection means stored in the communication connection means table, the communication power consumption per unit content capacity when transmission / reception is performed using the communication connection means, and the connection terminal power status table are stored. Based on the remaining amount of the battery 29-1, the content capacity that can be transmitted and received by the mobile terminal device 1-1 is calculated.

  The calculation unit 160-2 also calculates the content capacity that can be transmitted and received by the mobile terminal device 1-2 based on the remaining amount of the battery 29-2 (FIG. 2). Specifically, for each communication connection means stored in the communication connection means table, the communication power consumption per unit content capacity when transmission / reception is performed using the communication connection means, and the connection terminal power status table are stored. Based on the remaining amount of the battery 29-2, a content capacity that can be transmitted and received by the mobile terminal device 1-2 is calculated. In addition, the method similar to what was demonstrated about the residual amount of the battery 29-1 can be used for the acquisition method of the residual amount of the battery 29-2.

  The content capacity calculation by the calculation unit 160-2 will be described with a specific example. For example, if the remaining amount of the battery 29-1 (FIG. 2) is 10 mAh and the communication power consumption per packet for the communication connection means X is 0.1 mAh, the mobile terminal device 1-1 uses the communication connection means X. The content capacity that can be transmitted and received is 10 / 0.1 = 100 packets.

  The capacity acquisition unit 161-2 functions as a capacity acquisition unit that acquires the capacity of transmission / reception target content. Here, the transmission / reception target content for which the capacity is acquired is the content related to each thumbnail image displayed on the displayed content list screen. However, if the thumbnail image indicates a lower directory, each content in the lower directory is also a transmission / reception target content. When the content to be transmitted / received is content to be received from now on, the capacity acquisition unit 161-2 acquires the capacity from the mobile terminal device 1-1.

  The determination unit 162-2 determines whether or not the content to be transmitted / received can be transmitted / received based on the content capacity calculated by the calculation unit 160-2 and the capacity acquired by the capacity acquisition unit 161-2. Function as. More preferably, the determination unit 162-2 is acquired by the content acquisition unit 161-2 and the content capacity for each of the mobile terminal device 1-1 and the mobile terminal device 1-2 calculated by the calculation unit 160-2. Whether or not the content to be transmitted / received can be transmitted / received. Note that the determination unit 162-2 performs the above determination for each communication connection unit for each content to be transmitted and received.

  The process flow of the determination unit 162-2 will be described more specifically. The determination unit 162-2 first determines whether or not the content capacity calculated by the calculation unit 160-2 for the mobile terminal device 1-1 exceeds the capacity acquired by the capacity acquisition unit 161-2. Next, the determination unit 162-2 determines whether or not the content capacity calculated by the calculation unit 160-2 for the mobile terminal device 1-2 exceeds the capacity acquired by the capacity acquisition unit 161-2. . Then, when both of the determination results of the above two determinations are affirmative determinations, it is determined that the content to be transmitted / received can be transmitted / received. This determination result (hereinafter referred to as a final determination result) is obtained for each communication connection unit for each content to be transmitted and received.

  The determination of the determination unit 162-2 will be specifically described using the above example. The capacity of the content to be transmitted / received C1 is 70 packets, the content capacity that can be transmitted / received by the mobile terminal device 1-1 using the communication connection means X is 100 packets, and the mobile terminal device 1-2 is the communication connection means X. When the content capacity that can be transmitted / received using is 50 packets, the final determination result of the determination unit 162-2 is “transmission / reception of the transmission / reception target content C1 is impossible”. This is because when the transmission / reception target content C1 is transmitted / received using the communication connection means X, the battery 29-2 runs out during communication. In this example, for the transmission / reception target content C2 having a capacity of 30 packets, the final determination result of the determination unit 162-2 is “transmission / reception of the transmission / reception target content C2 is possible”. This is because even when the transmission / reception target content C2 is transmitted / received using the communication connection means X, neither of the batteries 29-1 and 2 is disconnected during communication.

  The connection status determination unit 16-2 creates a transfer power consumption table for each connection means for each content to be transmitted and received, and writes the determination result in the created transfer power consumption table for each connection means. Hereinafter, a specific description will be given while showing an example of the transfer power consumption table for each connection means.

  FIG. 5 is a diagram illustrating an example of the transfer power consumption table by connection means. As shown in the figure, the transfer power consumption table for each connection means indicates whether or not each call connection means can be used, communication power consumption per packet of the own terminal (mobile terminal device 1-2), and battery capacity of the own terminal. (Remaining amount of battery 29-2), transmission / reception status of own terminal (determination result of determination unit 162-2 regarding portable terminal device 1-2), per packet of connection destination terminal (mobile terminal device 1-1) Communication power consumption, battery capacity of connection destination terminal (remaining amount of battery 29-1), transmission / reception status of connection destination terminal (determination result of determination unit 162-2 regarding portable terminal device 1-1), transmission / reception both possible This is a table for storing a situation (final determination result of the determination unit 162-2), a connection destination condition, and a unit price per packet (communication cost).

  The connection status determination unit 16-2 holds a model of the transfer power table by connection means, and all possible communication connection means are prepared in advance for this model. In the example of FIG. 4, Bluetooth, Ir, Ir-SS (high-speed infrared communication), wireless LAN, five types of mobile phone networks (PDC (Personal Digital Cellular), WCDMA (Wideband Code Division Multiple Access), CDMA (Code Division Multiple Access), CDMA 1x, CDMA EvDO (Evolution Data Only), GSM (Global System for Mobile), GPRS (General Packet Radio Service), and PLC.

  First, the connection status determination unit 16-2 writes data “1” indicating that the communication connection means stored in the communication connection means table can be used in the “usability” column. On the other hand, for communication connection means not stored in the communication connection means table, data “0” indicating that the communication connection means is not usable is written in the “usability” column. In FIG. 5, for easy understanding, round marks are used instead of “1” and “0”. The same applies to the other columns described below.

Next, the connection status determination unit 16-2 writes the remaining amount of the battery 29-1 stored in the connection terminal power status table in the “battery capacity of the connection destination terminal” column. At this time, the connection status determination unit 16-2 may write only in the row where “1” is written in the “usability” column. The same applies to other columns to be described. Further, for the connection means “PLC” which is a connection means used when using the AC power supply, the connection status determination unit 16-2 may not write the remaining amount of the battery 29.
Further, the connection status determination unit 16-2 acquires the remaining amount of the battery 29-2 and writes it in the “battery capacity of own terminal” column.

  In addition, the connection status determination unit 16-2 displays the communication power consumption per unit content capacity when performing transmission / reception using each communication connection means in the “Communication power consumption per packet of own terminal” column and “Connection destination”. Write in the "Communication power consumption per packet of terminal" column.

  Next, the connection status determination unit 16-2 displays the determination results of the determination unit 162-2 regarding the mobile terminal device 1-1 and the mobile terminal device 1-2 as “transmission / reception possible status of the connection destination terminal” and “self Write in "Transmitting status of terminal". Furthermore, the connection status determination unit 16-2 writes the final determination result of the determination unit 162-2 in the “situation in which both sides can transmit and receive”. In each of these columns, data “1” representing “affirmation” is written when the determination result is affirmative, and data “0” representing “denial” is written when the determination result is negative. .

  Next, the connection status determination unit 16-2 writes the connection destination condition of each communication connection unit in the “connection destination condition of own terminal” column for the mobile terminal device 1-2. To give a specific example, first, for the communication connection means “Bluetooth”, data indicating “paired” is written when the connection is being established. For the communication connection means “wireless LAN”, the type of the access point to which the mobile terminal device 1-2 is connected is written. In FIG. 5, information indicating the name of the place where the access point is installed is written as this type. For communication connection means “mobile phone network”, “GSM”, and “GPRS”, information that affects charges such as the name of the service provider and the presence or absence of roaming is written. In addition, with respect to the communication connection means “PLC”, when performing PLC connection using an AC power source other than the AC power source directly connected to the mobile terminal device 1-2 (for example, the cradle performs communication processing on the PLC, and the mobile terminal device In the case of 1-2 only communicating with the cradle), data indicating “the terminal AC is not connected” is written to indicate that. In addition, the connection status determination unit 16-2 may write the communication rate of each communication connection unit in the “connection destination condition of own terminal” field.

  Similarly, the connection status determination unit 16-2 writes the connection destination condition of each communication connection unit in the “connection destination condition of connection destination terminal” column for the mobile terminal device 1-1. The connection status determination unit 16-2 receives the terminal device capability information (data transfer rate of the mobile terminal device 1-1 (communication rate) received by the terminal device capability information receiving unit 101-2 from the data necessary for the writing. ), Information indicating the contract carrier of the portable terminal device 1-1 (including information for identifying domestic and foreign carriers), and the like. A specific example is the same as that in the “connection condition of own terminal” field.

  Furthermore, the connection status determination unit 16-2 calculates a unit price per packet (communication cost) for the mobile terminal device 1-2 and writes it in the “unit price per packet” column. For this purpose, the connection status determination unit 16-2 holds a fee table (not shown), and uses this fee table and also uses the contents described in the “connection condition of own terminal” column as necessary. Thus, the unit price per packet is calculated.

  Furthermore, the connection status determination unit 16-2 calculates a unit price per packet (communication cost) for the mobile terminal device 1-1 and writes it in the “unit price per packet” column. Note that the connection status determination unit 16-2 acquires the data necessary for this writing from the terminal device capability information (such as the fee structure of each contract carrier) received by the terminal device capability information receiving unit 101-2. .

  The power display control unit 17-2 reads the determination result of the determination unit 162-2 from the transfer power consumption table for each connection unit for each content to be transmitted and received. Then, information indicating the read determination result is presented to the user using the main display unit 20. Thereby, the power display control unit 17-2 functions as a presentation unit.

  Specifically, the power display control unit 17-2 provides the user with information (hereinafter referred to as comprehensive information) based on the determination result of the determination unit 162-2 for each communication connection unit for each content to be transmitted and received. To present. Specific examples of the comprehensive information include information indicating that there is at least one communication connection unit that can transmit and receive (details will be described later). The power display control unit 17-2 also includes information indicating the determination result of the determination unit 162-2 for each communication connection means (hereinafter referred to as determination result information for each communication connection means) for each transmission / reception target content. To present. Hereinafter, a specific example will be described with reference to FIG. 4 again.

  In the example shown in FIG. 4, the type of the shaded image (the power display image) around each thumbnail image indicates general information about the transmission / reception content related to each thumbnail image. In the example of FIG. 3, three types of shading indicate “transmittable”, “not transmittable”, and “partially transmittable”, respectively.

  Here, “transmittable” indicates that, when the thumbnail image directly indicates the transmission / reception target content, there is at least one communication connection unit that can transmit / receive the transmission / reception target content. In addition, when the thumbnail image indicates a lower directory, it indicates that there is at least one communication connection means capable of transmitting and receiving for each of the transmission / reception target contents under the lower directory.

  “Unable to transmit” indicates that when the thumbnail image directly indicates the content to be transmitted / received, there is no communication connection means that can transmit / receive the content to be transmitted / received. Further, if the thumbnail image indicates a lower directory, it indicates that there is no communication connection means capable of transmitting / receiving any of the transmission / reception target contents under the lower directory.

  Further, “partially transmittable” is used when the thumbnail image indicates a lower directory, and a communication connection means that can transmit and receive a part of transmission / reception target contents under the lower directory. There is at least one, and the remaining part of the content to be transmitted / received indicates that there is no communication connection means capable of transmitting / receiving.

  Although the shaded image is used in the example shown in FIG. 3, it is needless to say that other images may be used. For example, a process of graying out those that cannot be transmitted (a process of displaying them in light gray and making them unselectable) or displaying a predetermined alert may be considered. Further, the background display may be changed in accordance with the comprehensive information related to the thumbnail image pointed by the user operation.

  In the example shown in FIG. 3, what is shown in the determination result presentation area D2 is the determination result information for each communication connection means. When one of the thumbnail images displayed as a list is pointed by a user operation, the power display control unit 17-2 displays determination result information for each communication connection means regarding the transmission / reception target content related to the pointed thumbnail image. Displayed in the determination result presentation area D2.

  Since the display space is usually insufficient, the power display control unit 17-2 displays the determination result information for each communication connection unit by the horizontal scroll display as shown in FIG. In the example of FIG. 3, the power display control unit 17-2 represents the determination result information for each communication connection means by a character string “BT: transmission possible WL: transmission impossible CN: transmission possible”, and is horizontally scrolling displayed. Is shown. Note that BT is an abbreviation for Bluetooth, WL is an abbreviation for a wireless LAN (Wireless LAN), and CN is an abbreviation for a cellular phone network.

  In the example shown in FIG. 3, the determination result information for each communication connection means is displayed in the determination result presentation area D2. For example, the determination result information for each communication connection means is displayed immediately below each thumbnail image. Also good.

  As described above, when a specific thumbnail image is selected by a user operation, the content transmission / reception unit 103-2 transmits or receives the transmission / reception target content related to the selected thumbnail image to or from the content transmission / reception unit 103-1. The reception process starts. At this time, the content transmission / reception unit 103-2 is one of one or more communication connection units that indicate that the content to be transmitted / received can be transmitted / received based on the determination result for each communication connection unit by the determination unit 162-2. It functions as a content transmission / reception unit that selects a communication connection unit and transmits or receives the content to be transmitted / received using the selected communication connection unit.

  In a specific example, first, when there is only one communication connection unit that indicates that transmission / reception is possible, the content transmission / reception unit 103-2 uses the communication connection unit to transmit or receive content to be transmitted / received. I do.

  On the other hand, when there are a plurality of communication connection means that indicate that transmission / reception is possible, the content transmission / reception unit 103-2 determines “connection destination condition of own terminal” “connection destination condition of connection destination terminal” in the transfer power consumption table by connection means. Referring to “unit price per packet of own terminal” “unit price per packet of connection destination terminal”, transmission / reception is performed using high-speed, reliable, and inexpensive communication connection means. As a specific example, communications related to roaming to foreign countries are often slower and easier to disconnect than other communications. Therefore, the content transmission / reception unit 103-2 determines that the other communication is “high speed” and “reliable” as compared to the communication related to roaming abroad. Note that priority may be given to the communication connection means in advance, and transmission / reception may be performed using a communication connection means having the highest priority among a plurality of communication connection means indicated to be capable of transmission / reception.

  By the way, even when transmission / reception is performed using a communication connection means that indicates that transmission / reception is possible, transmission / reception may fail for reasons other than battery exhaustion (for example, when the terminal is out of service area). Therefore, when transmission / reception fails (when an error occurs), the reservation control unit 15 reserves transmission / reception and performs transmission / reception again. Thereby, the reservation control part 15 functions as a reservation control means. The transmission / reception reservation is performed by writing the reservation registration information in the memory 32.

  The reservation control unit 15 also reserves transmission / reception even when the user performs an operation for transmission on a content to be transmitted / received that does not have any communication connection means that indicates that transmission / reception is possible.

  The re-transmission / reception may be performed when the cancellation of the reason for the failure to transmit / receive is monitored and the cancellation is detected. It may be performed periodically. Moreover, it is good also as performing by the following processes. That is, a transmission / reception server is prepared on the network. And the reservation control part 15 of the portable terminal device 1 of the transmission side uploads the content reserved for transmission / reception to this server. The server continues to transfer the uploaded content to the mobile terminal device 1 on the receiving side until the transmission is completed. If it carries out like this, the consumption of the battery 29 of the portable terminal device 1 of a transmission side can be suppressed. Note that the server may not send the content itself, but may send a guide mail to the mobile terminal device 1 on the receiving side. Then, the mobile terminal device 1 on the receiving side can download the content in the server according to the guidance mail. By doing so, it is possible to save resources of the radio channel from the server to the mobile terminal device 1 on the receiving side.

  Further, in the re-transmission, it is possible to “send only the summary” or “divide and send by the capacity that the communication partner can receive”.

  Note that the reservation control unit 15 may not perform the reservation control depending on the mobile terminal device 1 that is the connection destination. For example, in Bluetooth, for example, a mobile terminal device that cannot receive content, such as a headset or a speaker, may be designated as a content transmission destination. In this case, since it is clear that it will not be received no matter how many times it is retransmitted, reservation control is not performed.

Hereinafter, the processing of the mobile terminal device 1-2 will be described in more detail again with reference to the processing flow.
FIG. 6 is a flowchart showing a processing flow of the mobile terminal device 1-2. As shown in the figure, when the mobile terminal device 1-2 starts connection with the mobile terminal device 1-1 using any of the communication connection means (step S1), the communication connection means determination unit 102-2 The communication connection means that can be used for connection with the portable terminal device 1-1 that is the connection-destination portable terminal device is confirmed (step S2). In addition, the terminal device capability information receiving unit 101-2 inquires of the mobile terminal device 1-1 about the power status of the mobile terminal device 1-1 (remaining battery 29-1 or AC connection). Confirm (step S3). Then, the confirmed communication connection means is written in the communication connection means table, and the power status is written in the connection terminal power status table (step S4). At this time, the main control unit 10-2 displays an icon of the confirmed power status (step S5).

  Next, the main control unit 10-2 determines a time interval of a loop (loop processing of Step S3 to Step S11) (Step S6). This time interval is determined to be shorter when the mobile terminal device 1-1 and the mobile terminal device 1-2 are connected by communication using the always-connected communication connection means than when it is not. Further, this time interval is determined to be shorter as the communication fee is lower. Furthermore, the smaller the remaining amount of the battery 29-1 and the battery 29-2 at the time interval determination time, the longer is determined.

  After step S6, until the time indicated by the determined time interval elapses, the main control unit 10-2 waits for a content list screen display operation. It also waits for a manual confirmation request. Note that the manual confirmation means that the confirmation in step S3 is not performed automatically (regardless of the user's operation), but the confirmation in step S3 is performed according to the user's operation.

  When a content list screen display operation is performed (Yes determination in step S7), the main control unit 10-2 causes the connection status determination unit 16-2 to start a content list screen display process (step S8). Details of the content list screen display processing will be described later with reference to FIG.

  When a manual confirmation request is generated as a result of the user performing a “manual confirmation” start operation (affirmative determination in step S9), the main control unit 10-2 performs the process “manual confirmation”. (Step S10). In this case, the main control unit 10-2 exits the loop process of step S3 to step S11 and waits for the next operation of the user.

  When the time indicated by the time interval determined in step S6 elapses (positive determination in step S11), main controller 10-2 returns the process to step S3. The main control unit 10-2 may return the processing to step S3 with a trigger such as activation of mail, reception, taking a picture, creation of content for transmission, and the like.

  Next, FIG. 7 is a flowchart showing a processing flow of content list screen display processing performed by the mobile terminal device 1-2. As shown in the figure, the connection status determination unit 16-2 determines whether or not a predetermined time has elapsed since the transfer power consumption table for each connection unit was created last time (step S81). The previous creation here means creation in step S82 described later. It should be noted that it is preferable to always move to the process of step S82 immediately after the transition from step S7 to the content list screen display process.

  When it is determined in step S81 that the predetermined time has elapsed, the connection status determination unit 16-2 creates a transfer power table by connection means for each content in the directory to be displayed (step S82). Then, the power display control unit 17-2 presents whether or not transmission is possible for each content based on the created transfer power consumption table classified by connection means (step S83). A specific presentation method is as described above.

  After the transmission permission / inhibition is presented, the power display control unit 17-2 waits for a content point operation by the user. When a point operation is performed (Yes determination in step S84), the power display control unit 17-2 displays whether transmission is possible for each communication connection unit for the selected content based on the transfer power consumption table for each connection unit. (Step S85). Here, the power display control unit 17-2 adds and displays the remaining amount of the battery 29-1 and the remaining amount of the battery 29-2 for each communication connection unit for the selected content. It is good.

  In addition, after the power display control unit 17-2 presents transmission permission / inhibition, the content transmission / reception unit 103-2 waits for a transmission / reception instruction operation by the user. When a transmission / reception instruction operation is performed (Yes determination in step S86), the content transmission / reception unit 103-2 transmits / receives the content instructed to transmit using, for example, a communication connection unit with the highest priority (step S87). Then, it is determined whether or not transmission / reception has been completed. If the transmission / reception has not been completed (No determination in step S88), the reservation control unit 15-2 is caused to perform transmission / reception reservation (step S89).

  Furthermore, the power display control unit 17-2 determines whether or not the user has instructed to end the data folder display process, and if so (Yes in step S90), returns the process to the main control unit 10-2. The main control unit 10-2 repeats the process from step S1 in FIG. On the other hand, if not, the power display control unit 17-2 causes the connection status determination unit 16-2 to repeat the process of step S81 (negative determination of step S90).

As described above, the mobile terminal device 1-2 can prevent the battery of the mobile terminal device 1-1 that is a communication partner and its own battery from running out during content transmission / reception.
Also, the calculation unit 160-2 can calculate the content capacity that can be transmitted and received by the mobile terminal apparatuses 1-1 and 1-2 for each communication connection means such as a mobile phone network, a wireless LAN, a PLC, and Bluetooth. become.

  Further, the user can know information (the above-described comprehensive information) based on the determination result of the determination unit 162-2 for each communication connection unit. Similarly, the user can also know the determination result (determination result information for each communication connection means) of the determination unit 162-2 for each communication connection means.

Further, the content transmission / reception unit 103-2 can transmit / receive the content to be transmitted / received by the optimal communication connection means.
Furthermore, since the reservation control unit 15-2 is provided, even if transmission / reception fails for reasons other than battery exhaustion, transmission / reception can be performed again, so transmission / reception can be completed with certainty.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and the present invention can of course be implemented in various forms without departing from the scope of the present invention. It is.

  For example, the present invention can also be applied when there are a plurality of mobile terminal devices 1 on the receiving side, such as in the case of multicast transmission. In this case, in the mobile terminal device 1 on the transmission side, the remaining battery level is obtained from each mobile terminal device 1 on the reception side, and the above determination is performed for each mobile terminal device 1. It is preferable to present “transmittable” when it is determined that reception is possible, and to present “not transmittable” when any portable terminal device 1 is determined to be unable to receive. is there.

  In the above-described embodiment, the description has been made on the assumption that the communication power consumption is the same at the time of transmission and at the time of reception. When the difference amount is so large that it cannot be ignored, the calculation unit 160-2 uses the “communication power consumption per unit content capacity when transmitting using the communication connection unit” and the mobile terminal device 1-1 and the mobile phone. The terminal device 1-2 calculates the content capacity that can be transmitted, and uses the “communication power consumption per unit content capacity when receiving using the communication connection means” and the mobile terminal device 1-1 and the mobile device. It is desirable to calculate the content capacity that can be received by each terminal device 1-2. In that case, the determination unit 162-2 obtains the content capacity that can be transmitted by the mobile terminal device 1-2, the content capacity that can be received by the mobile terminal device 1-1, and the capacity obtained by the calculation unit 160-2. Based on the capacity acquired by the unit 161-2, it is determined whether the content to be transmitted can be transmitted, and the content capacity that can be received by the mobile terminal device 1-2 calculated by the calculation unit 160-2, It is desirable to determine whether or not the content to be received can be received based on the content capacity that can be transmitted by the mobile terminal device 1-2 and the capacity acquired by the capacity acquisition unit 161-2.

  Further, the determination unit 162-2 transmits and receives based on information indicating the CPU capability of the mobile terminal device 1-1, the processing memory amount of the mobile terminal device 1-1, and the remaining memory capacity included in the terminal device capability information. It may be determined whether or not it is possible. That is, the determination unit 162-2 may determine that transmission / reception is not possible when the CPU capability of the mobile terminal device 1-1 is lower than a predetermined value, and the processing memory amount or the remaining memory capacity of the mobile terminal device 1-1 is not sufficient. When the value is lower than the predetermined value, it may be determined that transmission / reception is impossible.

  In the above embodiment, the communication power consumption per packet has been described as different for each communication connection means. However, in actuality, it depends on the content specification such as the content transmission / reception mode (streaming or download) and the encoding method. Communication power consumption is different. Therefore, the calculation unit 160-2 acquires communication power consumption for each content specification, and the mobile terminal device 1-1 and the mobile terminal device 1-2 transmit and receive for each content specification using the acquired communication power consumption. The possible content capacity may be calculated. In this case, the determination unit 160-2 selects one of a plurality of content capacities calculated by the calculation unit 160-2 based on the content specification of each transmission / reception target content, and acquires the selected content capacity and the capacity acquisition. It is preferable to determine whether each content to be transmitted / received can be transmitted / received based on the capacity acquired by the unit 161-2.
