Description

  The present invention relates to a transmission system, an information processing apparatus, a program, and a transmission method.

  A video conference system is known as an example of a transmission system that performs a video conference or the like between a plurality of transmission terminals via a communication network such as the Internet. In such a video conference system, one transmission terminal transmits image data and audio data collected during the video conference to the other transmission terminal. The other transmission terminal receives the image data and the audio data, displays an image on a display or the like, and outputs a sound from a speaker, so that a video conference can be held between these transmission terminals.

  There is also known a text chat system in which text data is transmitted and received between a plurality of transmission apparatuses via a communication network such as the Internet to perform chat.

  A user who uses a general-purpose information processing apparatus such as a smart device as a transmission terminal can perform a text chat or a video conference, and it is desirable to start a video conference with a small number of operations from the text chat. Became. However, in general, the video conference system and the text chat system are independent of each other. Therefore, a technique for improving cooperation between independent systems has been devised (see, for example, Patent Document 1). Patent Document 1 discloses a linkage system that associates a telephone number with an e-mail address in two independent systems, an e-mail system and a telephone system.

  By the way, in the video conference system and the text chat system, in order for the user to communicate with the other party, the user may be required to be approved in advance. This is a measure for preventing an unknown person from requesting a video conference or text chat. Specifically, when Mr. A wants to communicate with Mr. B, Mr. A requests Mr. B to approve, and Mr. B approves Mr. B to be registered in Mr. A's address book. By being registered in the address book, Mr. A can request Mr. B for a video conference or text chat.

  Since the video conference system and the text chat system are independent systems, Mr. A cannot register Mr. B in the address book without receiving approval from Mr. B in each system. For example, even if Mr. B is registered in the address book of Mr. A in the text chat system, Mr. B is not registered in the address book of Mr. A in the video conference system. In this case, even if Mr. A is in a text chat with Mr. B, in order for Mr. A to start a video conference with Mr. B, Mr. A receives approval from Mr. B and enters Mr. A's address book in the video conference system. It is necessary to register Mr. B.

  As described above, there is a problem for users who use the two systems to register the other user in their address books.

  An object of this invention is to provide the transmission system which can reduce the burden of the user who utilizes two systems in view of the said subject.

  In view of the above problems, the present invention provides a first information processing apparatus that performs communication connection of first data between a first transmission terminal registered in first destination terminal information and a second transmission terminal, And a transmission system having a second information processing apparatus for performing communication connection of second data between the first transmission terminal and the second transmission terminal, from the first transmission terminal to A first determination unit configured to determine whether the second data communication connection to the second transmission terminal is possible; a determination result by the first determination unit; First identification information for identifying the transmission terminal and second identification information for identifying the second transmission terminal by the first information processing apparatus to the first information processing apparatus And whether or not the determination result includes communication connection possible If the second determination means determines that the communication connection is possible by the second determination means, the second identification information is associated with the first identification information. Communication connection means for performing communication connection of the first data between the first transmission terminal and the second transmission terminal even if not registered in the first destination terminal information.

  It is possible to provide a transmission system that can reduce the burden on the user who uses the two systems.

It is an example of the sequence diagram which shows the procedure in which a user starts a video conference using the destination list management table of a text chat management system.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  In this embodiment, two transmission systems cooperate. One of the two transmission systems is approved by the other transmission system for the other party registered in the address book. Thereby, the user who has registered the partner in the address book in one transmission system can start communication without registering the partner in the address book in the other transmission system. Therefore, the burden on the user who uses the two transmission systems can be reduced.

<About ID>
The ID of this embodiment is defined as follows.
ID of the video conference management system in the transmission system: Communication ID (used for authentication when the user logs in to the video conference management system). The user of the video conference service is identified by the communication ID. The communication ID is an example of first identification information and second identification information.
ID of the text chat management system in the transmission system: user ID (used for authentication when the user logs in to the text chat management system). The user of the text chat service is identified by the user ID. The user ID is an example of third identification information and fourth identification information. In the text chat service, an e-mail address or a skype (registered trademark) ID may be used for reasons such as lowering the hurdle when an individual uses it.

  As described above, the video conference service and the text chat service provide services separately using IDs assigned in different systems. The transmission system 1 according to the present embodiment links communication IDs and user IDs managed by two services, respectively. This allows users who have already started (connected) one service to communicate with only the other party registered in the address book, Communication can be started regardless of whether or not the other party is registered in the address book.

<Operation of transmission system>
Next, transmission / reception processing of each management information in a preparation stage before starting a call between the transmission terminal 10aa and the transmission terminal 10cc will be described with reference to FIGS. FIG. 6 is a sequence diagram showing processing in a preparation stage for starting a call between transmission terminals. FIG. 7 is a diagram schematically showing a destination list. Note that FIG. 6 shows a process in which various types of management information are transmitted and received through the management information session sei.

  First, when the user turns on the power switch 109 shown in FIG. 5, the operation input receiving unit 12 of the transmission terminal 10aa receives the power ON and turns on the power (step S21).

  The login request unit 13 automatically transmits login request information indicating a login request from the transmission / reception unit 11 to the transmission management system 50 via the communication network 2 in response to reception of power ON (step S22). This login request information includes a communication ID and a password for identifying the transmission terminal 10aa that is the own terminal as the request source. These communication ID and password are data read from the nonvolatile storage unit 1000 via the storage / reading processing unit 19 and sent to the transmission / reception unit 11. When the login request information is transmitted from the transmission terminal 10aa to the transmission management system 50, the transmission management system 50 that is the reception side can grasp the IP address of the transmission terminal 10aa that is the transmission side.

  Next, the authentication unit 52 of the transmission management system 50 searches the authentication management DB 3003 of the nonvolatile storage unit 3000 using the communication ID and password included in the login request information received via the transmission / reception unit 51 as search keys. Then, terminal authentication is performed by determining whether the same communication ID and the same password are managed in the authentication management DB 3003 (step S23). When it is determined that the request is a login request from the transmission terminal 10 having a legitimate use authority, the state management unit 53 stores, in the terminal management DB 3004, for each record indicated by the communication ID and destination name of the transmission terminal 10aa. The operating state, the reception date and time when the login request information is received, and the IP address of the transmission terminal 10aa are stored in association with each other (step S24).

  Then, the transmission / reception unit 51 of the transmission management system 50 transmits the authentication result information indicating the authentication result obtained by the authentication unit 52 to the request source terminal (transmission terminal 10aa) that requested the login via the communication network 2. (Step S25). In the present embodiment, the case where the authentication unit 52 determines that the terminal has a valid use authority will be described below.

  When the request source terminal (transmission terminal 10aa) receives the authentication result information indicating the result determined to be a terminal having a right to use, the transmission / reception unit 11 transmits to the transmission management system 50 via the communication network 2. The destination list request information indicating that the destination list is requested is transmitted (step S26). Thereby, the transmission / reception unit 51 of the transmission management system 50 receives the destination list request information.

Next, the terminal extraction unit 54 searches the destination list management DB 3002 using the communication ID “01aa” of the request source terminal (transmission terminal 10aa) that requested the login as a search key, and makes a call with the request source terminal (transmission terminal 10aa). The candidate communication ID of the destination terminal that can be extracted is extracted, and the destination name corresponding to this communication ID is extracted by reading from the terminal management DB 3004 (step S27). Here, each communication ID (01cc, 01c, 01d, 01e) of the destination terminal (10cc, 10c, 10d, 10e) corresponding to the communication ID “01aa” of the request source terminal (transmission terminal 10aa), and corresponding to these Next, the transmission / reception unit 51 of the transmission management system 50 extracts “destination list information (destination list frame, communication ID, destination name) including the communication ID and destination name extracted by the terminal extraction unit 54. ) "Is transmitted to the request source terminal (transmission terminal 10aa) (step S29).

  Thereby, in the request source terminal (transmission terminal 10aa), the transmission / reception unit 11 receives the destination list information, and the storage / reading processing unit 19 stores the destination list information in the volatile storage unit 2000 (step S30).

  As described above, in this embodiment, the transmission list is not managed by each transmission terminal 10, but the transmission management system 50 centrally manages the destination list information of all terminals. Therefore, a new transmission terminal 10 is included in the transmission system 1, a new model of the transmission terminal 10 is included instead of the transmission terminal 10 that is already included, and the appearance of the destination list frame is improved. Even if it is to be changed, since the transmission management system 50 handles all at once, the trouble of changing the destination list information on each transmission terminal 10 side can be saved.

  The terminal extraction unit 54 of the transmission management system 50 searches the terminal management DB 3004 using the destination terminal candidate communication ID (01cc, 01c, 01d, 01e) extracted by the terminal extraction unit 54 as a search key, For each communication ID extracted by the extraction unit 54, the corresponding operating state is read to obtain each operating state of the transmission terminals (10cc, 10c, 10d, 10e) as destination candidates (step S31).

  Next, the transmission / reception unit 51 includes the communication ID “01aa” as the search key used in step S27 and the operating state “ON line (call possible)” of the corresponding destination terminal (transmission terminal 10cc). The “terminal operating state information” is transmitted to the request source terminal (transmission terminal 10aa) via the communication network 2 (step S32). Further, the operating states of the transmission terminals 10c, 10d, and 10e) are individually transmitted to the request source terminal (transmission terminal 10aa).

  Next, the storage / read processing unit 19 of the request source terminal (transmission terminal 10aa) sequentially stores the operating state information of the transmission terminal 10 received from the transmission management system 50 in the volatile storage unit 2000 (step S33). Therefore, the request source terminal (transmission terminal 10aa) receives the status information of each terminal, so that the current time of the transmission terminal 10cc and the like that are candidates for the destination terminal that can talk to the request source terminal (transmission terminal 10aa) It is possible to acquire the operating status of each.

  Next, the destination list creation unit 17 of the request source terminal (transmission terminal 10aa) performs transmission as a destination candidate based on the destination list information stored in the volatile storage unit 2000 and the operating state information of the transmission terminal 10. A destination list reflecting the state of the terminal 10 is created. Further, the display control unit 16 displays the destination list on the display 120 shown in FIG. 2 (step S34).

  In the destination list shown in FIG. 7, icons 601 indicating the operating state of each transmission terminal 10 are “ON line (transmittable)”, “OFF line”, “ON line (transmittable)” from the top. ”And“ ON line (during a call) ”. In the video conference system as in the present embodiment, “transmittable” means “callable”.

  On the other hand, the terminal extraction unit 54 of the transmission management system 50 searches the destination list management DB 3002 based on the communication ID “01aa” of the request source terminal (transmission terminal 10aa) that requested the login, thereby requesting the request source terminal (transmission terminal). The communication ID (01cc, 01c, 01d, 01e) of the other request source terminal that has registered the communication ID “01aa” of 10aa) as the destination terminal candidate is extracted (step S35).

  Next, the terminal extraction unit 54 of the transmission management system 50 searches the terminal management DB 3004 based on the communication ID “01aa” of the request source terminal (transmission terminal 10aa) that has requested the login, and the request source that has requested the login The operating state of the terminal (transmission terminal 10aa) is acquired (step S36).

  Then, the transmission / reception unit 51 is set to “ON” in the terminal management DB 3004 among the transmission terminals (10cc, 10c, 10d, 10e) related to the communication ID (01cc, 01c, 01d, 01e) extracted in step S35. “Transmission terminal 10” including the communication ID “01aa” of the request source terminal (transmission terminal 10 aa) acquired in step S 36 and the operating state “ON line” is transmitted to the transmission terminal 10 that is “line”. (Steps S37-1, S37-2). As a result, the communication ID “01aa” of the request source terminal (transmission terminal 10aa) that requested the login and the operation to each of the other destination terminals that can talk using the request source terminal (transmission terminal 10aa) that requested the login as the destination. The status “ON line” can be conveyed.

  The transmission terminals 10d and 10cc display the operating state of the transmission terminal 10aa in the destination list (steps S38-1 and S38-2).

  On the other hand, the other transmission terminals 10 also perform the same processing as the processing of steps S22 to S38-1, 2 when the power switch 109 is turned on, as in step 21 described above.

  Thereafter, the user of the transmission terminal 10aa selects a desired transmission terminal with which communication is desired from the destination list displayed on the display 120 (S39a).

The operation input receiving unit 12 receives the press. The display control unit 16 displays the addition request reception screen data stored in the volatile storage unit 2000 on the display 120aa, thereby performing a process of receiving a destination candidate addition request (step S41). This addition request reception screen 610 is displayed on the destination list as shown in FIG.

  Next, the user a inputs the communication ID or terminal name of the transmission terminal to be a destination candidate on the addition request reception screen 610 shown in FIG. 9 by using the operation button 108 (here, the communication ID “01dc”). When the “Send Add Request” button 611 is pressed, the operation input receiving unit 12 receives the input of the user a. When the “Cancel” button 612 is pressed, the addition request reception screen 610 is deleted.

  The transmission / reception unit 11 of the request source terminal (transmission terminal 10aa) transmits addition request information indicating a destination candidate addition request to the transmission management system 50 via the communication network 2 (step S42). The additional request information includes a communication ID “01aa” of the request source terminal for identifying the request source terminal (transmission terminal 10aa) and a communication ID of the request destination terminal for identifying the request destination terminal (transmission terminal 10dc). “01dc” is included. Thereby, the transmission / reception unit 51 of the transmission management system 50 receives the additional request information.

  Next, in the transmission management system 50, the additional request management unit 59 stores the received communication ID “01aa” of the request source terminal in the communication ID field of the request source terminal of the new record in the additional request management DB. In addition to the management, the communication ID “01dc” of the request destination terminal is additionally stored and managed in the communication ID field of the request destination terminal of the new record (step S43).

  Next, the terminal state notification / acquisition unit 55 searches the terminal management DB 3004 based on the communication ID “01dc” of the request destination terminal to confirm the corresponding operation state (step S44).

  When the terminal state notification / acquisition unit 55 confirms that the operation state is the ON line but has not started a call (transmission), the transmission / reception unit 51 continues the request destination terminal (transmission terminal 10dc). ), Additional approval request information indicating a request for approving the additional request is transmitted (step S45). This additional approval request information includes the communication ID “01aa” of the request source terminal. As a result, the transmission / reception unit 11 of the request destination terminal (transmission terminal 10dc) receives the additional approval request information.

  Next, the request destination terminal (transmission terminal 10dc) performs approval, rejection, or hold processing for the addition request (step S46). Here, step S46 will be described in detail with reference to FIGS.

  First, when the additional approval request information is received by the request destination terminal (transmission terminal 10dc), it is stored in the volatile storage unit 2000 by the storage / read processing unit 19 (step S46-1). When additional approval request information is sent one after another, they are stored in the volatile storage unit 2000 one after another.

  Next, the storage / reading processing unit 19 tries to extract the communication ID of the request source terminal included in the additional approval request information from the volatile storage unit 2000 (step S46-2). When a plurality of additional approval request information is stored, the communication IDs of request source terminals included in the additional approval request information are extracted one by one.

  When the communication ID of the request source terminal is extracted in step S46-2 (step S46-3, YES), the display control unit 16 is shown in FIG. 11 for the display 120dc. In this manner, the addition request approval acceptance screen 620 is displayed (step S46-4).

When the terminal name of the request source terminal is displayed, the additional approval request information transmitted in step S45 includes the terminal name of the request source terminal in addition to the communication ID of the request source terminal. In this case, the terminal name of the request source terminal is also extracted when the operating state is confirmed in step S44.

  Next, when the user d presses the “Yes”, “No”, or “Cancel” button on the addition request reception screen illustrated in FIG. 11, the operation input reception unit 12 displays “ An instruction of “approval”, “rejection”, or “hold” is accepted (step S46-5). And it returns to step S46-2 and repeats a process by trying extraction of communication ID of the remaining request origin terminals memorize | stored in the volatile memory | storage part 2000. FIG. When the communication IDs of all request source terminals are extracted as “01aa” (step S46-3, NO), the process of step S46 ends.

  Subsequently, returning to FIG. 8, the transmission / reception unit 11 of the request destination terminal (transmission terminal 10 dc) transmits additional request response information indicating an additional request response of approval, rejection, or hold to the transmission management system 50 (step). S47). As a result, the transmission / reception unit 51 of the transmission management system 50 receives the additional request response information. Here, the case where the addition request response indicates “approval” will be described.

  Next, the additional request management unit 59 uses the communication ID “01dc” of the request destination terminal associated with the communication ID “01aa” of the request source terminal in the additional request management DB 3006, and the communication of the request source terminal in the additional request management DB 3006. It is additionally managed in association with the communication ID “01aa” of the request source terminal in the same destination list management DB 3002 as the ID “01aa” (step S48).

  If the additional request response indicates “reject”, in step S48, the additional request management unit 59 deletes the record of the communication ID “01dc” of the rejected request destination terminal in the additional request management DB 3006. To do. If the additional request response indicates “hold”, in step S48, the additional request management unit 59 does not perform additional management, and the additional request management unit 59 does not delete the record. Leave it alone.

  Next, the terminal extraction unit 54 searches the terminal management DB 3004 based on the communication ID “01aa” of the request source terminal and the communication ID “01dc” of the request destination terminal, thereby corresponding each information (destination name, (Operating state) is extracted (step S49).

  Then, the transmission / reception unit 51 transmits the addition completion information to the request source terminal (transmission terminal 10aa) and the request destination terminal (transmission terminal 10dc), respectively (steps S50-1, 2). Among these, the addition completion information transmitted to the request source terminal (transmission terminal 10aa) includes a message indicating that the addition has been completed, and information (communication ID, destination name, and operation) of the request destination terminal (transmission terminal 10dc). State). That is, only the information (communication ID, destination name, and operating state) of the request destination terminal (transmission terminal 10dc) portion in the destination list is transmitted to the request source terminal (transmission terminal 10aa), and the entire destination list is renewed. It is not sent. On the other hand, the addition completion information transmitted to the request destination terminal (transmission terminal 10dc) includes a message indicating that the addition has been completed, and information (communication ID, destination name, and operation) of the request source terminal (transmission terminal 10aa). State).

  In the request source terminal (transmission terminal 10aa) and the request destination terminal (transmission terminal 10dc), each display control unit 16 displays a screen indicating completion on each display (120aa, 120dc) (step S51-1). , 2). FIG. 12 shows an addition completion screen 630 displayed on the display 120aa on the request source terminal (transmission terminal 10aa) side. When the user a presses the “confirm” button 631, the display of the addition completion screen 630 is ended. In this way, since the addition completion screen 630 shown in FIG. 12 is displayed, the user a can quickly notice that the addition request has been approved, and thus can immediately start a meeting with the added destination terminal. There is an effect.

  On the transmission management system 50 side, when the processing of steps S50-1 and S50-2 is completed, the additional request management unit 59 deletes the record of the communication ID “01dc” of the approved request destination terminal in the additional request management DB. As a result, all the processing of the destination candidate addition request is completed (step S52).

  8 to 12, the transmission terminal 10aa registers the transmission terminal 10dc in its own destination list management table. However, if the transmission terminal 10 dc is not registered in its own destination list management table, the transmission terminal 10 dc cannot video conference with the transmission terminal 10 aa. For this reason, the process of FIGS. 8-12 also performs transmission terminal 10dc.
