Description

  The present invention relates to a content distribution system during a call, and in particular, a content distribution system capable of transmitting or acquiring an image or video at an arbitrary timing without recognizing the other party's telephone number or address information during the call. The present invention relates to a content-linked distribution apparatus used in such a system.

  With the recent development of communication technology, a system for transmitting and receiving both voice and images in both directions is being realized. A typical example is a videophone. In addition to a videophone, for example, in a packet voice call system such as an IP phone, images stored on a server in the network during a call are automatically displayed on the caller terminal. A system is known (for example, see Patent Document 1). In this system, when dialing a destination terminal, content location information (for example, URL) on the network is acquired, and this content information is stored in association with the telephone number of the destination terminal (or the gateway terminal address). The When a voice call is connected to the other terminal, specifically, when the connection message packet arrives at the calling terminal, the video receiving software is automatically started up at the calling terminal. The content associated with the counterpart terminal is acquired.

In addition, a system is known that transmits and receives images and the like by inputting a mail address of the other party during a call.
JP 2001-308933 A

  However, in the above-described system, the calling terminal only acquires the content on the network with the connection of the voice call as a trigger, and the usage mode is very limited. For this reason, a system that can transmit and receive content in a simple and free manner during a call is desired.

  Accordingly, the present invention provides a system in which a calling party or a partner (called party) terminal can send and receive or acquire content stored on a network or in a terminal at any timing during a call. Objective.

  It is also an object of the present invention to provide a system that allows a desired content to be transmitted and received at an arbitrary timing without the terminal device recognizing the telephone number or address information of the partner terminal during a call.

  In order to achieve the above object, the present invention pays attention to call connection information accumulated when voice communication is established, and using this call connection information, the user can use the other party's phone number or mail during a call. A system capable of transmitting and receiving images and videos without knowing the address, IP address, etc. is constructed.

  Specifically, in the first aspect of the present invention, content stored on the network is distributed from the second terminal of the content provider to the first terminal of the content acquirer at an arbitrary timing. Provide a content-linked distribution device. The content-linked distribution device, during a call between the first terminal and the second terminal, a call management unit that manages a call correspondence relationship between the first terminal and the second terminal, a content on the network, and a first that provides this A content management unit that manages content correspondence between the two terminals. When a call management unit receives a request for content from the first terminal or the second terminal during a call, the call management unit searches for a call correspondence between the first terminal and the second terminal, Provided to the content management unit along with the request for content. The content management unit identifies the requested content on the network based on the call correspondence and the content correspondence, and causes the first terminal to acquire the identified content.

  In order to cause the first terminal to acquire content, the content management unit notifies the first terminal of location information (such as URL) of the identified content via the call management unit. Alternatively, the content specified by the content management unit itself may be acquired from the network, and the acquired content may be distributed to the first terminal via the call management unit.

  In the second aspect of the present invention, when both the first terminal and the second terminal have contents on the network, respectively, on the network at any timing during a call between the first terminal and the second terminal. A content-linked distribution device that enables distribution of content to any terminal is provided. The content-linked distribution device is adapted to handle correspondence between a call management unit that manages a correspondence relationship of the call, a content on the network, and the first and second terminals during a call between the first terminal and the second terminal. A content management unit for managing the relationship, and when the call management unit receives a request for the content on the network from the first terminal or the second terminal during a call, the call management unit The correspondence relationship of the call is searched, it is determined whether the request for the content is an acquisition request or a transmission request, and the determination result is supplied to the content management unit together with the correspondence relationship of the call and the request for the content. The content management unit specifies the requested content on the network based on the correspondence relationship of the call and the content correspondence relationship, and determines which terminal the distribution destination of the specified content should be based on the determination result. The content is determined, and the determined distribution destination is made to acquire the content.

  According to a third aspect of the present invention, there is provided a call management device that enables content distribution from the second terminal to the first terminal at an arbitrary timing when the content is held in the second terminal of the provider. To do. The call management device receives a call acquisition database or a transmission request for the content from the first terminal or the second terminal during a call, and a call management database for managing a correspondence relationship between the first terminal and the second terminal during the call A request receiving unit that, when receiving an acquisition request or a transmission request, searches the call management database and notifies the second terminal of identification information of the first terminal.

  In the fourth aspect of the present invention, when both the first terminal and the second terminal have content in the terminal, both transmit the content to the partner terminal at an arbitrary timing, or the partner terminal Provided is a call management device that enables acquisition from a terminal. The call management device includes: a call management database that manages a correspondence relationship between a first terminal and a second terminal when a call is established between the first terminal and the second terminal; A request receiving unit that receives a request for the content from one terminal or a second terminal, and a request determination unit that determines whether the request for the content is a content acquisition request or a transmission request. When the request is received, the unit searches the call management database to identify the correspondence relationship of the call between the first terminal and the second terminal, and based on the determination result of the request determination unit, It is specified which of the terminal and the second terminal is the content transmission side terminal, and the identification information of the other terminal is supplied to the transmission side terminal.

  In a content distribution system using such a content-linked distribution device or a call management device, even if one terminal does not recognize the telephone number or address information of the other terminal during a call, it is stored on the network or in the terminal. The content can be supplied to the partner terminal or acquired from the partner terminal at an arbitrary timing.

  FIG. 1 is a schematic diagram showing a system configuration according to the first embodiment of the present invention. In the first embodiment, the content stored on the network is transmitted or acquired during a call by the content transmission side (provider side) terminal or the receiver terminal without recognizing the other party's telephone number or address information. The structure which can be performed is disclosed.

  The content distribution system 10 includes a receiver terminal 11 connected via the network 1, content provider terminals 12 </ b> A and 12 </ b> B, and a content storage unit 40 that stores content of the content provider on the network 1. In addition, a call management unit 20 that connects a call between the receiver terminal 11 and the content provider terminal 12 and manages the correspondence between both terminals during the call using a terminal ID such as a telephone number and address information, and a content storage unit The content management unit 30 manages the correspondence between the content stored in 40 and the terminal ID (phone number or address information) of the provider who provided the content. The call management unit 20 and the content management unit 30 constitute a content linked distribution device 50.

  In the configuration example of FIG. 1, the call management unit 20 obtains content from the call management database 21 that stores the correspondence between the telephone numbers or address information of both terminals in a call, and the receiver terminal 11 or the content provider terminal 12. Or it has the request | requirement receiving part 22 which receives and identifies a transmission request and content selection information.

  On the other hand, the content management unit 30 includes a content management database 31 that stores the correspondence between the telephone number or address information of the content provider and the content stored in the content storage unit 40, and stores the content location or It has the notification part 32 which transmits content itself.

  The content distribution system 10 is basically realized by including a call management function, a content management function, a content storage function, a request reception function, and a notification function, and these functions are realized in any arrangement configuration. Is optional. In the example of FIG. 1, the notification management database 21 and the request receiving unit 22 are realized in the same call management unit 20, and the content management database 31 and the notification unit 32 are realized in the same content management unit 30. Each may exist independently.

  The receiver terminal 11 is a terminal device that can acquire content (HTTP communication) at the same time as a call, and is, for example, a mobile terminal having a multi-access function, a PC (IP phone) capable of calling, or the like. The content provider terminals 12A and 12B may be mobile phones or fixed telephones.

  FIG. 2 is a schematic diagram illustrating content delivery during a call triggered by a transmission request from a content provider as a first example of the first embodiment (when content is on a network). In the example of FIG. 2, the call management unit 20 in the system 10 of FIG. 1 is realized by the exchange 20A, the content management unit 30 is realized by the management server 30A, and the content storage unit 40 is realized by the content server 40A. In the following, referring to FIG. 2, a desired content is transmitted to the receiver terminal 11 without recognizing the telephone number of the receiver terminal 11 by issuing a content transmission request from the provider telephone terminal 12 </ b> B. The structure to perform is demonstrated.

  The content provider who is the owner of the provider terminal 12 is an arbitrary service provider such as a hotel, a restaurant, a beauty salon, a bookstore, a travel agency, and the telephone number, password, URL, URL to the management server 30A in advance. Is registered, and contents such as images and videos to be provided to the content server 40A are registered. In the example of FIG. 2, the content provider is a restaurant, and contents such as the type and price of the course provided by the restaurant, the in-store photo, and the surrounding map are registered in the content server 30A.

  The user of the receiver terminal 11 calls the provider's telephone number in the normal manner, and a call is established between the receiver terminal 11 and the provider terminal 12 via the exchange 20A (arrow (1)). Call information indicating a correspondence relationship of a call established between the receiver terminal 11 and the provider terminal 12 is managed by the exchange 20A and can be referred to the management server 30A (arrow (2)). .

  The user of the receiver terminal 11 starts a call with the provider and talks about an appropriate course and price in order to reserve dinner. In the middle of the conversation, the provider, for example, to visually recognize the recommended course and store atmosphere, “I will send you the recommended course and store atmosphere. A map will also be attached.” And a transmission request (transmission trigger) of a predetermined image is transmitted from the provider terminal 12 (arrow (3)). At this time, neither the provider nor the provider terminal 12 recognizes the telephone number of the user's receiver terminal 11 at all, and it is not necessary to input the address of the receiver terminal 11. A transmission request from the provider terminal 12 is sent to the management server 30A via the exchange 20A.

  The management server 30A specifies the recipient terminal 11 based on the call information managed by the exchange 20A. At the same time, the URL of the image selected by the provider is determined with reference to the content management database 31 owned by the self (reference (4)). Then, a content reception trigger including URL information is transmitted to the identified recipient terminal 11 (arrow (5)). The recipient terminal 11 acquires content from the content server 40A on the network 1 automatically or by a user operation or the like, and displays it on the screen (arrow (6)). Since the user of the receiver terminal 11 receives the image in real time during the call, the contents of the course and the atmosphere in the store can be visually understood.

  When the content received by the terminal 11 is accompanied by audio reproduction such as a video, the provider transmits a call resumption trigger (broken line arrow (7)), and the call between the user of the receiving terminal 11 and the provider is made. Resumed.

  FIG. 3A shows a configuration example of the call management database 21 included in the exchange 20A, and FIG. 3B shows a configuration example of the content management database 31 included in the management server 30A. The call management database 21 associates the telephone number of the calling party (content receiver in the example of FIG. 2) with the telephone number of the called party (content provider in the example of FIG. 2), and continues the call. Hold this combination. The call information is deleted after the call ends. Even when the caller makes a call without notification, the exchange 20A knows the caller number and can manage the callee number in association with each other.

  The content management database 31 manages the location information of the content provided by the content provider in association with the telephone number of the image provider (including address information in the case of an IP phone). The contents can be changed as appropriate, and each time, the association with the provider's telephone number (or address information) is newly saved.

  FIG. 4 is a content transmission processing sequence triggered by a transmission request in the system of FIG. First, a connection is established between the content transmission side terminal 12 and the reception side terminal 11, and a call is started (step S101). At this time, the correspondence relationship of the call between the reception side terminal 11 and the transmission side terminal 12 is stored in the call management database 21 of the exchange 20A. During the call, the transmission side terminal 12 transmits a content transmission request at an arbitrary timing (step S102). The content transmission request includes the telephone number (or address information) of the transmission side terminal 12 and the content selection information. This content transmission request is received by the request receiving unit 22 of the exchange 20A.

  The exchange 20A searches the call management database 21 for the call destination, that is, the telephone number (or address information) of the receiving terminal 11 (step S103), and the telephone numbers (or address information) of both terminals 11 and 12 and the content selection information. Is sent to the management server 30A (step S104). The management server 30A searches for the location (URL) of the content from the content management database 31 based on the telephone number (or address information) of the transmission side terminal 12 and the content selection information (step S105).

  The notification unit 32 of the management server 30A notifies the position information of the searched content to the receiving terminal 11 (step S106). Based on this position information, the receiving terminal 11 acquires content from the content server 40A (step S107).

  FIG. 5 is a modification of the processing sequence of FIG. In the example of FIG. 4, the management server 30A notifies only the location information of the content to the receiving terminal 11 (S106), but in the example of FIG. 5, the management server 30A acquires the content from the content server 40A on the network, The acquired content is transmitted to the receiving terminal 11.

  In FIG. 5, the sequence from the call start (S101) to the content position determination (S105) is the same as in the example of FIG. If the position of the content is retrieved in S105, the management server 30A accesses the content server 40A and acquires the content (step S116). The notification unit 32 of the management server 30A transmits the acquired content to the receiving terminal 11 (step S117). In either case of FIG. 4 or FIG. 5, the transmitting terminal 12 only needs to send a transmission request without recognizing the telephone number of the other party during the call. The receiving terminal 11 can view content such as images transmitted during a call in real time. Since the content is stored in the receiving terminal 11, it can be viewed even after the call ends. 4 and 5, the exchange 20A and the management server 30A may be realized as one device as shown in FIG.

  6 and 7 are diagrams illustrating an example of an operation when a transmission trigger is sent from the provider (transmission side) terminal 12 during a call. As described above, the transmission trigger is a signal that does not require the telephone number or mail address of the terminal on the partner side (that is, the receiver side). In the example of FIG. 6, a transmission request is transmitted by a combination of button operations of a call terminal such as a fixed phone or a mobile phone. The content provider inputs the service identification number and the content number at the provider terminal 12 used for the call while viewing the provided information 19 such as a web page displayed on a browser such as a PC or printed matter, for example. To do. When the provider terminal 12 uses the PB signal, for example, “2”, “4”, and “2” are pressed in order to specify the service number, and then the content number “3” is pushed and then “ #"push. In addition to the PB signal, it is also possible to use USSD (Unstructured Supplementary Service Data), which is information transfer means between the mobile device and the network application, which is defined by the GSM standard. As an operation example in that case, “*”, “2”, “4”, “2” are operated as service identification numbers by the terminal button, the content number “3” is pressed, and “#” is pressed. As a result of such an operation, the content selection information is sent to the exchange 20A.

  In the example of FIG. 7, a transmission request is sent by operating a Web page at the call terminal itself that has made a call. In this case, the provider terminal 12 needs to be a mobile terminal or an IP phone that can view a Web page while making a call. The requester of transmission selects an image to be transmitted with the radio button 16 on the Web page and clicks the transmission button 15.

  The operation method shown in FIGS. 6 and 7 is merely an example of a means for sending a transmission trigger, and a transmission request may be issued by creating a special protocol or signal in the terminal 12 in order to realize content distribution during a call. Is possible.

  Next, with reference to FIG. 8 and FIG. 9, a second mode when content is on a network will be described. In the second aspect, content distribution during a call is enabled by using a content acquisition request transmitted from the content receiver side as a trigger.

  In the sequence diagram of FIG. 8, first, a connection is established between the receiving side terminal 11 that is the calling party and the transmitting side terminal 12 that is the called party, and a call is started (step S201). During a call, for example, when a conversation for a restaurant or hotel reservation is being performed, the caller receiving terminal 11 transmits a content acquisition request (step S202). The transmission of the acquisition request at this time is the same as the transmission of the transmission request shown in FIGS. The caller can issue an acquisition request for the content provided by the service provider at any timing by inputting the service information identification number and the content number described in the advertisement or print medium during the call.

  The exchange 20A receives the acquisition request from the receiving terminal 11 and refers to the call management database 21 to search for the telephone number or address information of the call destination, that is, the provider terminal 12 (step S203). The exchange 20A manages the telephone numbers (or address information) of both the receiving and transmitting terminals 11 and 12 and the content selection information specified by the receiving terminal 11 based on the correspondence relationship of the retrieved call. The server 30A is notified (step S204).

  The management server 30A specifies the location of the content on the network based on the telephone number (or address information) of the transmission side terminal 12 and the content selection information (step S205). And the position of content, such as URL, is notified to the receiving terminal 11 (step S206). The receiving terminal 11 acquires content from the predetermined content server 40A based on the received content position information (step S207).

  FIG. 9 is a modification of the sequence diagram of FIG. In FIG. 8, similarly to the processing sequence of FIG. 5, in step S205, the management server 30A specifies the position of the content on the network, and accesses the content server 40A to acquire the content (step S216). Then, the acquired content itself is transmitted to the receiving terminal 11 (step S217).

  In either case, the user of the receiving terminal 11 can acquire desired content from the network simply by selecting the desired content on the terminal during a call.

  Next, a content distribution system according to a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, content distribution during a call when content is on the terminal side will be described.

  In FIG. 10, the content distribution system 70 includes a content receiving terminal 11, a content provider terminal 12, and a call management device 20, and the provider terminal 12 is provided with a content management function 30 and a content storage function 40. ing. The content management function 30 of the provider terminal 12 includes a notification function as shown in FIG.

  Similar to the call management unit of the first embodiment, the call management device 20 is a call management database that manages the correspondence between calls when a call is established between the receiver terminal 11 and the provider terminal 12. 21. Moreover, it has the request | requirement receiving part 22 which receives the acquisition request or transmission request with respect to the content stored in the provider terminal 12 from the receiver terminal 11 or the provider terminal 12. FIG.

  FIG. 11 shows a sequence of content distribution processing triggered by a content transmission request from the provider side (transmission side) terminal 12 during a call. In the example of FIG. 11, the call management device 20 is realized by an exchange 20A, and a content management unit 30 and a content storage unit 40 are provided in the transmission side terminal 12.

  First, for example, a call is established between the receiving side terminal 11 and the transmitting side (provider side) terminal 12 by a call from the receiving side terminal 11 (step S301). At this time, the correspondence relationship between the call at the receiving terminal 11 and the transmitting terminal 12 is stored in the call management database 21 of the exchange 20A. During the call, the transmission side terminal 12 issues a content transmission request at an arbitrary timing (step S302). The transmission request includes the telephone number (or address information) of the transmission side terminal 12 and the content selection information. At this time, the transmitting terminal 12 does not recognize information such as the telephone number of the receiving terminal 11 on the other side, and transmits only a transmission request by a simple operation as shown in FIG.

  The transmission request is received by the exchange 20A, and the exchange 20A searches the telephone number (or address information) of the receiving terminal 11 that is the other party of the call from the correspondence relationship of the call managed by the call management database 21 (step S303). The retrieved telephone number (or address information) of the receiving terminal 11 is transmitted to the transmitting terminal 12 (step S304). The content management unit 30 of the transmission side terminal 12 transmits predetermined content from the content storage unit 40 to the reception side terminal 11 based on the received telephone number or address information of the reception side terminal 11 (step S305). Such information about the receiving terminal 11 can be used only within the transmitting terminal 12 and is not displayed to the user.

  FIG. 12 is a processing sequence in the case where the receiving side terminal 11 issues an acquisition request for the content of the transmitting side terminal 12, contrary to FIG. 11. In the example of FIG. 12, it is desirable that the transmission side terminal 12 that owns the content sets whether or not the content can be acquired in advance, as indicated by the broken line block.

  First, a call is established between the reception side terminal 11 and the transmission side terminal 12 (step S401), and the correspondence relationship of this call is stored in the exchange 20A. During the call, the receiving terminal 11 transmits a content acquisition request at an arbitrary timing (step S402). The content acquisition request includes the telephone number (or address information) of the receiving terminal 11 and content selection information.

  The exchange 20A that has received the acquisition request searches for the telephone number (or address information) of the transmission side terminal 12 from the correspondence relationship of the call stored in the call management database 21 (step S403), and transmits based on the search result. The content selection information selected by the receiving terminal 11 is sent to the side terminal 12 (step S404), and the telephone number or address information of the receiving side terminal 11 is transmitted (step S405).

  If the sending terminal 12 has not set whether or not the content can be acquired before the call is established, when the telephone number or address information of the receiving terminal 11 is received from the exchange 20A, select whether or not the content can be acquired by pop-up or the like. It may also be performed (step S406). Whether or not the content can be acquired may be set in advance either as shown by a broken line block or when the other party's telephone number is acquired (S406). If the content acquisition is permitted, the transmission side terminal 12 transmits the content to the reception side terminal 11 (step S407).

  As described above, in the second embodiment, when the content is in one of the terminals that are in a call, the acquisition request from the receiving side or the content possession can be obtained without inputting the destination telephone number or address information of the call. Content is automatically distributed using a transmission request from the user as a trigger.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, bi-directional content distribution is realized when both terminals in a call have content on the network or on the terminal.

  FIG. 13 is a schematic configuration diagram of a content distribution system 80 which is the first aspect of the third embodiment. In the system of FIG. 13, both the first terminal 11 and the second terminal 12 store content in the content storage unit 40 on the network 1. The content distribution system 80 includes a content-linked distribution device 55 that includes a content management unit 30 and a call management unit 60. The content distribution system includes a content management unit 30 that manages the correspondence between the content on the network 1 and the content provider, and a call management unit that manages the correspondence of a call between the first terminal 11 and the second terminal. 60.

  As shown in FIG. 3B, the content management unit 30 stores the first terminal 11 and the location information of the content provided by the user of the first terminal 11 in association with each other in the content management database 31. Further, the location information of the content provided by the second terminal 12 and the user of the second terminal 12 is associated and managed. Therefore, the user of the first terminal 11 registers the content to be provided in advance in the content storage unit 40 on the network 1 and also stores the content such as the telephone number (or address information) and the URL in the content management unit 30. Register location information. Similarly, the user of the second terminal 12 registers the content to be provided to the content storage unit 40 on the network 1, and registers his / her telephone number (or address information) and the location information of the content in the content management unit 30. To do.

  The call management unit 60 stores and manages the correspondence relation of this call in the call management database 21 during a call between the first terminal 11 and the second terminal 12. When the request receiving unit 22 receives a request for content on the network 1 from the first terminal 11 or the second terminal during the call, the call management database 21 is referred to and the correspondence between the first terminal 11 and the second terminal 12 is received. Search the other party's phone number or address information based on the relationship. The request determination unit 23 determines whether the received request is a content acquisition request or a transmission request. This is because both the first terminal 11 and the second terminal can be the content provider side and the content receiving side.

  FIG. 14 is a schematic configuration diagram of a content distribution system 90 according to the second aspect of the third embodiment. In the system of FIG. 14, both the first terminal 11 and the second terminal 12 have content on the terminal. Therefore, the first terminal 11 and the second terminal 12 each have a content management unit 30 and a content storage unit 40.

  The content distribution system 90 of FIG. 14 includes a call management device 60 that manages the correspondence relationship of calls between the first terminal 11 and the second terminal 12. Similar to the call management unit 60 of FIG. 13, the call management device 60 stores and manages the correspondence relationship of this call in the call management database 21 during a call between the first terminal 11 and the second terminal 12. When a request for content is received from the first terminal 11 or the second terminal by the request receiving unit during a call, the correspondence relationship between the first terminal 11 and the second terminal is searched with reference to the call management database 21. . The request determination unit 23 determines whether the received request is an acquisition request or a transmission request.

  As shown in FIGS. 13 and 14, in the third embodiment, both the first terminal 11 and the second terminal 12 can be the content providing side and at the same time the content receiving side. Therefore, each generates and transmits a content acquisition request and a transmission request. For this reason, it is necessary to include in the request from the terminals 11 and 12 information for identifying whether it is a transmission request or an acquisition request.

  FIG. 15 is a processing flow of the call management unit (or call management device) 60 of FIGS. 13 and 14. First, a call is set between the first terminal 11 and the second terminal 12, and a call is started (step S501). At this time, the correspondence relationship of the call between the first terminal 11 and the second terminal is stored in the call management database 21. During a call, when the request receiving unit 22 receives a content request from the terminal (step S503), the request determining unit 23 obtains whether the request is a transmission request from the type information such as the type flag included in the content request. (Step S505).

  If the request is a transmission request, based on the correspondence relationship of the call stored in the call management database 21, the telephone number of the other party terminal that is the transmission destination is searched (step S507). If the content is on the network 1 as shown in FIG. 13, the telephone number (or address information) of both terminals and the content selection information including the type information are notified to the content management unit 30 (step S513). Thereafter, the processing after step S105 in FIG. 4 or FIG. 5 is performed. On the other hand, as shown in FIG. 14, when the content is on the terminal side that has issued the transmission request, the telephone number (or address information) of the receiving side terminal that is the destination terminal is notified to the transmitting side terminal (step S513). Thereafter, the content is transmitted from the transmission side terminal to the reception side terminal.

  When the request is an acquisition request (NO in S505, S509), based on the correspondence relationship of the call stored in the call management database 21, the telephone number of the partner terminal (sending terminal) serving as the content providing source, etc. Is searched (step S511). As shown in FIG. 13, when the content is on the network 1, the content management unit 30 is notified of the telephone number (or address information) of both terminals and the content selection information including the type information (step S515). Thereafter, the processing after step S205 of FIG. 8 or 9 is performed. On the other hand, as shown in FIG. 14, when the content is in the transmission-side terminal that is the acquisition destination, the telephone number (or address information) of the terminal that issued the acquisition request is notified to the transmission-side terminal on the other side (step S515).

  FIG. 16 shows an example of an operation procedure when the request types are notified in the terminals 11 and 12. FIG. 16A shows a method for inserting a transmission / acquisition flag into a content request using a PB signal by operating a button on the terminal. In the example of FIG. 16A, for example, after pushing service identification numbers “2”, “4”, and “2”, flag information for identifying a transmission request or an acquisition request is inserted, and a content number is pushed. End with "#". The flag information is, for example, a transmission request if “0” and an acquisition request if “1”.

  Alternatively, as illustrated in FIG. 16B, a configuration may be used in which an acquisition request or a transmission request is selected on a Web page (request type confirmation page) displayed on the terminal. Thereafter, depending on whether the acquisition request is selected or the transmission request is selected, a transition is made to the content list page of the other party or the self content list page, and the desired content is selected.

  Of course, these are examples of request generation including transmission / acquisition type information, and a specific protocol or signal may be created in the terminals 11 and 12 as described above. As described above, in the third embodiment, during a call between terminals each holding content on a network or on a terminal, a transmission request or acquisition request issued at an arbitrary timing is used as a trigger, and the other party's telephone number or Bidirectional content distribution is possible without inputting address information.

  As described above, by managing the telephone numbers (or address information) of both the calling side and the called side in association with each other, the network or The content stored in the terminal can be transmitted.
