The billing management unit transfers the content information read request to the wireless terminal that is the transmission source and stores a communication fee related to the wireless terminal, while the advertisement information is downloaded from the advertisement server to the broadband router. Thereafter, the advertisement server transmits advertisement end information to the broadband router, and the broadband router that has received the advertisement end information outputs the received content information read request to the information terminal, and sends the content information read request. Based on this request, the received information terminal receives the desired configuration. The billing management unit transmits a billing management request to the broadband router at a predetermined time interval, and transmits the billing information to the wireless terminal that is the transmission source of the content information read request via the broadband router. The content distribution method, wherein the broadband router that has received the management request is a procedure for transferring the number of times of transmission of the advertisement information to the billing management unit as a billing management response.

  As described above, according to the first and third aspects of the present invention, for example, content information stored in an information terminal installed in a home or the like is stored in a wireless communication area such as a hot spot where the owner is out. In content distribution to be downloaded to a wireless terminal, the wireless terminal sends a content information read request by designating a predetermined port number of the broadband router, and the broadband router that has received this request corresponds to the designated port number. It is possible to obtain access destination information of advertisement information, download the corresponding advertisement information from the advertisement server specified based on this information, and send it to the requesting wireless terminal. Communication fees and the number of accesses to the advertisement information can be stored and managed. When the user of the wireless terminal reads and browses the content information from the information terminal, the advertisement information is also transferred from the advertisement server and browsed, whereby the advertisement provider of the advertisement information Etc. can provide a content communication system and a content communication method that have a special effect such as paying the full amount or a part of the communication fee of the wireless terminal to reduce or reduce the burden fee of the user.

  Further, according to the invention described in claim 2, since the broadband router obtains the access destination information of the advertisement information corresponding to the port number designated by the wireless terminal as the URL, the broadband router is connected to the advertisement server and the advertisement information. The use of this broadband router makes it possible for the user of the wireless terminal to recognize desired content information and the transmission without being aware of advertisement information at all. It is easy to construct a content distribution system that can acquire and browse the advertisement information.

  Hereinafter, each example will be described with respect to the best mode for carrying out the present invention.

  An example of the overall configuration of the content distribution system in the first embodiment is shown in FIG. In the figure, reference numeral 1 denotes an information terminal having a large capacity data recording unit such as an HDD (hard disk drive) (not shown), 2 denotes data output from the information terminal 1 to the telecommunications network 8 described later or from the telecommunications network 8 side The data input to the information terminal 1 is relayed between the information terminal 1 and the telecommunications network 8, the storage unit 2a capable of temporarily storing the relayed transmission data, at least the port number and the address of the advertisement server 3 to be described later A broadband router including an advertisement server address table storage unit 2b that stores an advertisement server address table associated with information and the like, and a control unit 2c that controls the output timing of the relayed transmission data, etc. Advertising server that stores still image information, video information, audio information, graphics information, etc. (hereinafter referred to as advertising information) 4 is a content server that stores still image information, moving image information, audio information, a program, etc. (hereinafter referred to as content information) held by the content provider, and 5 is related to charging for packet communication charges of the wireless terminal 7 described later. A charge management unit for storing and managing information, 6 is a wireless access point for establishing and relaying communication between the wireless terminal 7 and the telecommunication network 8, and 7 is capable of communicating within the wireless communication area of the wireless access point 6 8 is a telecommunications network in which data communication is performed by IP protocol (IP) control as represented by the Internet.

  In this case, at least the broadband router 2, the advertisement server 3, the content server 4, the charge management unit 5, and the wireless access point 6 are connected to the telecommunications network 8, and data communication between each unit is performed via the telecommunications network 8. It is done.

  The telecommunications network 8 may be a network in which a plurality of networks are connected via a relay device such as a router depending on the scale and configuration of the entire network system. Only the network 8 is shown.

  The information terminal 1 is premised on that when the wireless terminal 7 accesses, the power is turned on and information can be read out.

  Next, the advertisement server address table will be described with reference to FIG. As shown in the figure, the advertisement server address table records at least one combination information corresponding to at least the port number of the broadband router 2 and the access destination information (hereinafter referred to as advertisement address) of the advertisement information. It is a table and is stored in the advertisement server address table storage unit 2b. Then, for example, when the wireless terminal 7 designates a predetermined port number of the broadband router 2 and a file name of desired content information and accesses via the wireless access point 6 and the telecommunication network 8, the control of the broadband router 2 is performed. The unit 2c refers to the advertisement server address table, acquires an advertisement address corresponding to the designated predetermined port number, and connects to the advertisement address.

  For example, according to the example of the advertisement server address table shown in FIG. 2, the wireless terminal 7 within the communication range of the wireless access point 6 can communicate with the wireless access point 6 in order to specify a file name of desired content information. When accessing the port number “82” of the broadband router 2 via the network 8, the control unit 2c refers to the advertisement server address table of the same figure stored in the advertisement address table storage unit 2b and port number “82”. The advertisement address “http://www.eiga-fan-club.com/next_movie.mpg” is acquired as a URL corresponding to the URL. Then, the control unit 2c downloads the advertisement information specified by the advertisement address from the advertisement server 3, temporarily stores it in the storage unit 2a, and the content data relating to the file name of the desired content information supplied from the information terminal 1 And the temporarily stored advertisement information are combined in a predetermined order and transferred to the access source wireless terminal 7. In this way, the broadband router 2 realizes a port redirection function using the advertisement server address table.

  This advertisement address table needs to be created in advance by receiving the advertisement address information from the advertisement server 3 and stored in the advertisement server address table storage unit 2b.

  Next, with respect to the content distribution system according to the first embodiment, first, a basic communication sequence example will be described with reference to the sequence diagram of FIG. 3 in order to help understanding of the operation of this example. In other words, in the example of the figure, it is assumed that there is no charge management unit 5 and the wireless terminal 7 reads content information stored in the large-capacity storage unit of the information terminal 1. The figure also shows a sequence example when the broadband terminal 2 is accessed by designating a predetermined port number from the wireless terminal 7.

  According to the figure, the wireless terminal 7 specifies a port number “80”, for example, and transmits a content information read request to the broadband router 2 via the wireless access point 6 and the communication network 8 (sequence S31). The content information read request is made up of information specifying the location of the information terminal 1 in which the desired content information is stored and the content information, for example, specifying a URL related to the desired content information. .

  Next, the control unit 2c of the broadband router 2 refers to the advertisement server address table stored in the advertisement server address table storage unit 2b, and acquires the advertisement address corresponding to the designated port number “80”. Then, the corresponding advertisement server 3 is accessed based on the advertisement address (sequence S32), and the corresponding advertisement information is downloaded to the storage unit 2a (sequence S33). Thus, it is desirable that the advertisement information is temporarily stored in the storage unit 2a of the broadband router 2. That is, once the advertisement information is downloaded, it can be supplied to the wireless terminal 7 any number of times without being downloaded again from the advertisement server 3 according to the judgment of the broadband router 2. This is because it can be reduced.

  Next, the control unit 2c controls the timing for outputting the downloaded advertisement information, and transfers the advertisement information to the wireless terminal 7 via the telecommunication network 8 and the wireless access point 6 based on this timing (sequence S34). ). The advertisement information transfer sequence (sequences S33 and S34) from the advertisement server 3 to the wireless terminal 7 via the broadband router 2 is repeatedly executed until all designated advertisement information has been transferred.

  On the other hand, before the transfer of the repeatedly executed advertisement information ends, the control unit 2c supplies the content information read request received from the wireless terminal 7 to the information terminal 1 (sequence S35).

The information terminal 1 that has received the content information read request reads the content information indicated by the request from the large-capacity storage unit and transfers it to the broadband router 2 (sequence S36). Next, the broadband router 2 transfers the transferred content information to the wireless terminal 7 that requested the content as a transmission destination (sequence S37).
Through the above basic sequence, the wireless terminal 7 can acquire the advertisement information and the content information.

  Next, with respect to the content distribution system of the first embodiment, the operation including the charge management unit 5 that manages the communication fee of the wireless terminal 7 will be described together with the sequence example of FIG. This figure shows a sequence example when the broadband terminal 2 is accessed by designating a predetermined port number from the wireless terminal 7. According to the figure, since the wireless terminal 7 accesses the content information held by the information terminal 1, for example, a port number “82” is designated and a content information read request is transmitted via the wireless access point 6 and the telecommunications network 8. Is transmitted to the charge management unit 5 (sequence S41). The charging management unit 5 charges the communication fee of the wireless terminal 7 using, for example, a packet-based method, but the wireless terminal 7 may be authenticated here in order to confirm the legitimacy of access of the wireless terminal 7 . This authentication method includes, for example, a mobile phone number if the wireless terminal 7 is a mobile phone, an IP address if it is a PDA (Personal Digital Assistant) terminal, etc., a card number if it has an IC card, etc. The identification number unique to the wireless terminal 7 is used.

  When the wireless terminal 7 is authenticated, if this result is valid, the charge management unit 5 transfers the content information read request to the broadband router 2. If the authentication is not performed, the data is transferred to the broadband router 2 as it is (sequence S42).

  When the broadband router 2 receives the content information read request supplied from the billing management unit 5, the control unit 2c receives the advertisement server stored in the advertisement server address table storage unit 2b, as in the basic sequence example shown in FIG. With reference to an address table (for example, FIG. 2), an advertisement address (in FIG. 2, “http://www.eiga-fan-club.com/next_movie.mpg”) corresponding to the port number “82” is acquired. Then, the corresponding advertisement server 3 is accessed based on this advertisement address (sequence S43), and the corresponding advertisement information is downloaded to the broadband router 2 (sequence S44), where the downloaded advertisement is also used in this sequence example. Information data is temporarily stored in the storage unit 2a. Before the process is started.

  Next, the temporarily stored advertisement information is transferred to the charge management unit 5 (sequence S45), and transferred from the charge management unit 5 to the wireless terminal 7 via the telecommunication network 8 and the wireless access point 6 (sequence). S46). Here, the charge management unit 5 controls to store the packet communication fee related to the communication of the wireless terminal 7.

  On the other hand, when the transfer of the advertisement information from the advertisement server 3 to the broadband router 2 is completed, the advertisement end information is transmitted from the advertisement server 3 to the broadband router 2 (sequence S47). By this advertisement end information, the broadband router 2 can recognize the end of transfer of the advertisement information. In addition, as another method for recognizing the end of the transfer of the advertisement information, when the broadband router 2 accesses the advertisement server 3, if the file size or advertisement playback time of the advertisement information to be downloaded is acquired, It is possible to determine the end of advertisement without receiving the advertisement end information.

  Next, the broadband router 2 transmits to the information terminal 1 the content information read request received and held from the charging management unit 5 (sequence S48). Then, the information terminal 1 reads the designated content information stored in the large-capacity storage unit based on the received content information read request and transfers it to the broadband router 2 (sequence S49). Next, the broadband router 2 transfers the supplied content information to the charge management unit 5, and the control unit 2c increments and stores the number of times the advertisement information is transmitted (sequence S50). The supplied advertisement information is transferred to the requesting wireless terminal 7 via the telecommunication network 8 and the wireless access point 6 (sequence S51).

  Here, when the advertisement information is temporarily stored in the storage unit 2a of the broadband router 2 when the transfer of the content information to the wireless terminal 7 is completed, the broadband router 2 stores the temporarily stored advertisement information. It can be transferred again (sequence S52, S53). That is, in this example, the advertisement information is transferred once before and after the transferred content information is transferred.

On the other hand, the charge management unit 5 transmits a charge management request to the broadband router 2 at a predetermined time interval in order to confirm the number of times the advertisement information has been transmitted to the wireless terminal 7 (sequence S54), and receives the charge management request. The broadband router 2 that has transferred the number of times that the advertisement information has been transferred to the wireless terminal 7 (the number of times that the increment process has been stored) is transferred to the charging management unit 5 as a charging management response (sequence S55).
As a result, the charge management unit 5 can manage the communication fee of the user of the wireless terminal 7 based on the number of times the advertisement information is transferred and the communication fee of the wireless terminal 7.

  As described above, for example, when content information recorded in an information terminal installed at home or the like is downloaded to a wireless terminal in a wireless communication area such as a hot spot when the owner is out, a conventional wireless terminal By using the content distribution system according to the first embodiment for a packet communication fee that has been expensive, when the content information is read from the information terminal and viewed, the advertisement information is also transferred from the advertisement server and viewed. Accordingly, the content communication system, the content communication method, and the like, which have a special effect that the advertisement provider or the like bears the full amount or a part of the communication fee of the wireless terminal, thereby reducing or reducing the burden fee of the user, And a broadband router can be provided.

Thus, the home server 10 that has received the digital broadcast can record the content information in the large-capacity storage unit 10a and the advertisement information.

  Here, the control unit 10c creates an advertisement information table as illustrated in FIG. 6 based on the received advertisement information and records it in the large-capacity storage unit 10a. The advertisement information table in the figure shows which advertisement information should be accessed at least for each received content information. For example, as the content information, the program “masterpiece special feature” has a playback time of “118 minutes”. This means that the three advertisement addresses shown in the figure are accessed.

  Next, as described in the first embodiment, the home server 10 that has received the content information read request from the wireless terminal 7 refers to the advertisement information table illustrated in FIG. 6 and transfers the corresponding advertisement information to the wireless terminal 7. A processing sequence example will be described with reference to the sequence diagram of FIG. In the figure, the wireless terminal 7 transmits a content information read request to the charging management unit 5 via the wireless access point 6 and the telecommunication network 8 in order to download the content information held by the home server 10 (sequence S71). .

  Next, billing management unit 5 transmits the received content information read request to home server 10 (sequence S72). The control unit 10c of the home server 10 authenticates the access of the wireless terminal 7 that transmitted the request, and refers to the advertisement information table stored in the large-capacity storage unit 10a if it is confirmed that the access is appropriate. Then, the control unit 10c accesses the advertisement server 3 based on the advertisement address corresponding to the desired content information described in the advertisement information table (sequence S73), and downloads the corresponding advertisement information to the home server 10 (sequence). S74). In this case, the downloaded advertisement information data is temporarily stored in the storage unit 10a.

  Next, the temporarily stored advertisement information is transferred to the charge management unit 5 (sequence S75), and transferred from the charge management unit 5 to the wireless terminal 7 via the telecommunication network 8 and the wireless access point 6 (sequence). S76). Here, the charge management unit 5 controls to store the packet communication fee related to the communication of the wireless terminal 7.

  When the transfer of the advertisement information from the advertisement server 3 to the home server 10 is completed, the advertisement end information is transmitted from the advertisement server 3 to the home server 10 (sequence S77). From this advertisement end information, the home server 10 can recognize the end of transfer of the advertisement information.

  Next, when the home server 10 receives the advertisement end information, the home server 10 transfers the content information related to the received content information read request to the charging management unit 5 (sequence S78), and the charging management unit 5 stores the received content information. The data is transferred to the wireless terminal 7 via the telecommunication network 8 and the wireless access point 6 (sequence S79).

  On the other hand, the charge management unit 5 transmits a charge management request to the home server 10 at a predetermined time interval in order to confirm the number of times the advertisement information has been transmitted to the wireless terminal 7 (sequence S80), and receives the charge management request. The home server 10 transmits the number of times the advertisement information has been transferred, that is, information of once in the example of FIG. 7 to the charging management unit 5 as a charging management response (sequence S81).

  As described above, for example, a digital broadcast is received by a home server installed at home or the like, the received content information is stored in the home server, and the owner wirelessly communicates in a wireless communication area such as a hot spot on the go. When downloading to the terminal, when using the content distribution system according to the present embodiment 2 that has conventionally been charged as a packet communication fee of the wireless terminal, when reading and browsing the content information from the information terminal, The advertisement information is also transferred from the advertisement server and viewed, so that the advertisement provider etc. pays all or part of the communication fee of the wireless terminal, etc. so that the user's burden charge is free or reduced Content communication system, content communication method, and broadband router having the effect of It can be provided.
