Description

The present invention relates to a transmission system, a text chat management system , a program and a transmission method.

A video conferencing system is known as an example of a transmission system for conducting a video conferencing or the like between a plurality of transmission terminals via a communication network such as the Internet. In such a video conferencing 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 the image on a display or the like, or outputs the audio from the speaker, so that a video conference can be held between these transmission terminals.

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

Users who use general-purpose information processing devices such as smart devices as transmission terminals can perform text chat and video conferencing, and it is also desirable to start video conferencing from text chat with a small number of operations. Became. However, in general, video conferencing systems and text chat systems are independent of each other. Therefore, a technique for improving the cooperation of independent systems has been devised (see, for example, Patent Document 1). Patent Document 1 discloses a cooperation 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 a video conferencing system or a text chat system, a user may be required to be approved by the other party in advance in order for the user to communicate with the other party. This is a measure to prevent strangers from requesting video conferencing or text chat. Specifically, when Mr. A wants to communicate with Mr. B, Mr. A requests approval from Mr. B, and when Mr. B approves, Mr. B is 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 conferencing system and the text chat system are independent systems, Mr. A cannot register Mr. B in the address book without obtaining approval from Mr. B in each system. For example, suppose that Mr. B is registered in the address book of Mr. A in the text chat system, but Mr. B is not registered in the address book of Mr. A in the video conferencing system. In this case, even if Mr. A has a text chat with Mr. B, in order for Mr. A to start a video conference with Mr. B, Mr. A receives the approval of Mr. B and enters the address book of Mr. A in the video conference system. It is necessary to register Mr. B.

As described above, there is a problem that it becomes a burden for the user who uses the two systems to register the other user in each address book.

In view of the above problems, an object of the present invention is to provide a transmission system capable of reducing the burden on users who use the two systems.

In view of the above problems, the present invention is a transmission system having a video conference management system for making a communication connection of a video conference service and a text chat management system for making a communication connection of a text chat service different from the video conference service. The text chat service has a storage means for associating and storing the identification information of the user of the text chat service and the identification information of the user of the video conference service, which are permitted to cooperate with the video chat service. The management system is a receiving means for receiving a video conference request from a user who has logged in to the text chat service with another user who has logged in to the text chat service, a user who has requested the video conference, and the other user. When the identification information of the above is stored in the storage means as the identification information of the user who has permitted the text chat service and the video conference service to cooperate with each other, the video conference service is requested in response to the request of the video conference. It has a service calling means for requesting the video conference management system to start a video conference between users who have logged in based on the user's identification information.

It is possible to provide a transmission system capable of reducing the burden on the user who uses the two systems.

It is a schematic diagram of an example of a transmission system. This is an example of a hardware configuration diagram of a video conferencing terminal. This is an example of a hardware configuration diagram of a mobile terminal. This is an example of a hardware configuration diagram of a relay device, a transmission management system, and a program providing system. This is an example of a functional block diagram of a transmission management system and a transmission terminal. This is an example of a sequence diagram showing processing in the preparatory stage for starting a call between transmission terminals. This is an example of a diagram schematically showing a destination list. This is an example of a sequence diagram showing additional processing of destination candidates.

This is an example of a sequence diagram showing a procedure for a user to start a video conference using a 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, the two transmission systems work together. The other transmission system obtains approval from one of the two transmission systems for the other party registered in the address book. As a result, a user who has registered the other party in the address book in one transmission system can start communication without registering the other party 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.
-Video conferencing management system ID among transmission systems: Communication ID (used for authentication when a user logs in to the video conferencing management system). The communication ID identifies the user of the video conferencing service. The communication ID is an example of the first identification information and the second identification information.
-Text chat management system ID of the transmission system ... User ID (used for authentication when a 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 the third identification information and the fourth identification information. In the text chat service, an e-mail address or Skype (registered trademark) ID may be used for the purpose of lowering the hurdle for personal use.

In this way, the video conferencing service and the text chat service provide services separately using IDs assigned in different systems. The transmission system 1 of the present embodiment links the communication ID and the user ID managed by the two services. As a result, if users who have already started (connected) communication with one service, even if the other service allows communication only to the other party registered in the address book, Communication can be started regardless of whether the other party is registered in the address book.

The ID of the present embodiment indicates identification information such as a language, characters, symbols, or various marks used to uniquely identify a transmission terminal or a user who uses the transmission terminal. Further, the communication ID may be identification information in which at least two of the above languages, characters, symbols, and various signs are combined.

<Operation of transmission system>
Next, with reference to FIGS. 6 and 7, the transmission / reception processing of each management information in the preparatory stage before starting the call will be described between the transmission terminal 10aa and the transmission terminal 10cc. FIG. 6 is a sequence diagram showing a process in the preparatory 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 management information is transmitted / received by 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 accepts the power ON and turns the power ON (step S21).

Then, the login request unit 13 automatically transmits the login request information indicating the login request from the transmission / reception unit 11 to the transmission management system 50 via the communication network 2 when the power is turned on (step S22). The login request information includes a communication ID and a password for identifying the transmission terminal 10aa, which is the own terminal as the request source. These communication IDs and passwords are data read from the non-volatile 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 on the receiving side can grasp the IP address of the transmission terminal 10aa on the transmitting side.

Next, the authentication unit 52 of the transmission management system 50 searches the authentication management DB 3003 of the non-volatile 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. , 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 login request is from the transmission terminal 10 having a legitimate usage authority, the state management unit 53 sends the terminal management DB 3004 to the terminal management DB 3004 for each record indicated by the communication ID and the destination name of the transmission terminal 10aa. The operating state, the date and time when the login request information was 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 requesting terminal (transmission terminal 10aa) that has 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 legitimate usage authority will be continuously described below.

When the requesting terminal (transmission terminal 10aa) receives the authentication result information indicating the result of being determined to be a terminal having a legitimate usage authority, the transmission / reception unit 11 sends to the transmission management system 50 via the communication network 2. , Sends the destination list request information indicating that the destination list is requested (step S26). As a result, 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 requesting terminal (transmission terminal 10aa) that requested the login as a search key, and makes a call with the requesting terminal (transmission terminal 10aa). The communication ID of the candidate of the destination terminal that can be used is extracted, and the destination name corresponding to this communication ID is extracted by reading from the terminal management DB 3004 (step S27). Here, the respective communication IDs (01cc, 01c, 01d, 01e) of the destination terminals (10cc, 10c, 10d, 10e) corresponding to the communication ID "01aa" of the requesting terminal (transmission terminal 10aa), and corresponding to these. Next, the transmission / reception unit 51 of the transmission management system 50 is subjected to "destination list information (destination list frame, communication ID, destination name) including the communication ID and the destination name extracted by the terminal extraction unit 54. ) ”Is transmitted to the requesting terminal (transmission terminal 10aa) (step S29).

As a result, in the requesting 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 the present embodiment, the transmission management system 50 centrally manages the destination list information of all the terminals, instead of managing the destination list information in each transmission terminal 10. Therefore, the transmission system 1 includes a new transmission terminal 10, a new model transmission terminal 10 is included in place of the already included transmission terminal 10, and the appearance of the destination list frame is improved. Even if the change is made, the transmission management system 50 side collectively handles the change, so that it is possible to save the trouble of changing the destination list information on each transmission terminal 10 side.

Further, the terminal extraction unit 54 of the transmission management system 50 searches the terminal management DB 3004 using the communication ID (01cc, 01c, 01d, 01e) of the destination terminal candidate extracted by the terminal extraction unit 54 as a search key, and searches for the terminal. By reading out the corresponding operating state for each communication ID extracted by the extraction unit 54, each operating state of the transmission terminal (10cc, 10c, 10d, 10e) as a destination candidate is acquired (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 status information" is transmitted to the requesting terminal (transmission terminal 10aa) via the communication network 2 (step S32). Further, each operating state of the transmission terminal 10c, 10d, 10e) is individually transmitted to the requesting terminal (transmission terminal 10aa).

Next, the storage / reading 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 requesting terminal (transmission terminal 10aa) can communicate with the requesting terminal (transmission terminal 10aa) by receiving the status information of each of the above terminals, such as the transmission terminal 10cc, which is a candidate for the destination terminal. It is possible to acquire the operating status of each of.

Next, the destination list creation unit 17 of the requesting terminal (transmission terminal 10aa) transmits 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. Create a destination list that reflects the status of the terminal 10. 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 status of each transmission terminal 10 are "ON line (transmission possible)", "OFF line", and "ON line (transmission possible)" from the top. , And "ON line (during a call)". Further, in the video conferencing system as in the present embodiment, "transmission possible" means "call possible".

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 has made a login request, thereby causing the request source terminal (transmission terminal). The communication IDs (01cc, 01c, 01d, 01e) of another requesting terminal that has registered the communication ID "01aa" of 10aa) as a candidate for the destination terminal are 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. Acquire the operating state of the terminal (transmission terminal 10aa) (step S36).

Then, among the transmission terminals (10cc, 10c, 10d, 10e) related to the communication ID (01cc, 01c, 01d, 01e) extracted in step S35, the transmission / reception unit 51 is set to "ON" in the terminal management DB 3004. The "terminal status information" including the communication ID "01aa" of the requesting terminal (transmission terminal 10aa) acquired in step S36 and the operating status "ON line" is transmitted to the transmission terminal 10 which is a "line". (Steps S37-1, S37-2). As a result, the communication ID "01aa" of the requesting terminal (transmission terminal 10aa) for which the login request is made, and the operation of each of the other destination terminals capable of making a call to the requesting terminal (transmission terminal 10aa) for which the login request is made. The state "ON line" can be transmitted.

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

On the other hand, when the power switch 109 is turned on, the other transmission terminal 10 also performs the same processing as in steps S22 to S38-1,2.

After that, the user of the transmission terminal 10aa selects a desired transmission terminal to communicate with from the destination list displayed on the display 120 (S39a).

Next, the transmission / reception unit 11 of the transmission terminal 10aa contains start request information indicating that communication is to be started, including the communication ID "01aa" of the transmission terminal 10aa and the communication ID "01cc" of the transmission terminal 10cc which is the destination terminal. , Transmit to the transmission management system 50 (step S39b).

As a result, the transmission management system 50 reads the IP address associated with the communication ID from the terminal management table and establishes a video conference session between the transmission terminal 10aa and the transmission terminal 10cc (S39c).

<< Additional processing of destination candidates >>
Subsequently, the process of adding the destination candidate will be described with reference to FIGS. 8 to 12. In the present embodiment, the request source terminal (transmission terminal 10aa) makes a request to add the request destination terminal (transmission terminal 10dc) to its own destination list. Note that FIG. 8 is a sequence diagram showing additional processing of destination candidates. FIG. 9 is a diagram schematically showing an additional request reception screen 610. FIG. 10 is a flowchart showing the process of approval or rejection. FIG. 11 is a diagram schematically showing an additional request approval acceptance screen 620. FIG. 12 is a diagram schematically showing the addition completion screen 630.

First, when the user a of the requesting terminal (transmission terminal 10aa) operates the operation button 108, the "add destination" button 602 shown at the lower right of the destination list shown in FIG. 7 is pressed. , The operation input receiving unit 12 accepts the press. The display control unit 16 displays the additional request reception screen data stored in the volatile storage unit 2000 on the display 120aa, thereby performing a process of receiving the additional request of the destination candidate (step S41). The additional request acceptance 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 the destination candidate on the additional request reception screen 610 shown in FIG. 9 by the operation button 108 (here, the communication ID "01dc"). When the "send additional request" button 611 is pressed, the operation input receiving unit 12 accepts the input of the user a. When the "Cancel" button 612 is pressed, the additional request acceptance screen 610 is deleted.

The transmission / reception unit 11 of the request source terminal (transmission terminal 10aa) transmits additional request information indicating an additional request for a destination candidate to the transmission management system 50 via the communication network 2 (step S42). The additional request information includes the communication ID "01aa" of the request source terminal for identifying the request source terminal (transmission terminal 10aa) and the communication ID of the request destination terminal for identifying the request destination terminal (transmission terminal 10dc). "01dc" is included. As a result, 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 of 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 status notification / acquisition unit 55 confirms the corresponding operating status by searching the terminal management DB 3004 based on the communication ID “01dc” of the request destination terminal (step S44).

Then, when it is confirmed by the terminal status notification / acquisition unit 55 that the operating state is the ON line but the call (transmission) has not started, the transmission / reception unit 51 continues to use the request destination terminal (transmission terminal 10dc). ), The additional approval request information indicating the request for whether or not to approve the additional request is transmitted (step S45). The additional approval request information includes the communication ID "01aa" of the requesting 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 10 dc) processes the approval, rejection, or hold of the additional request (step S46). Here, this step S46 will be described in detail with reference to FIGS. 10 and 11.

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 / reading 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 attempts to extract the communication ID of the requesting 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 the requesting terminal included in the additional approval request information are extracted one by one.

Then, when the communication ID of the requesting terminal is extracted by step S46-2 (step S46-3, YES), the display control unit 16 is shown in FIG. 11 with respect to the display 120dc. As described above, the additional request approval acceptance screen 620 is displayed (step S46-4).

The communication ID of the request source terminal or the name of the request source terminal is displayed on the additional request approval acceptance screen 620, and the user d on the request destination terminal (transmission terminal 10 dc) side displays the request destination terminal (transmission terminal 10 dc). "Yes" button 621 pressed by user d when approving registration in the destination list of the requesting terminal (transmission terminal 10aa), when rejecting registration of this user d in the destination list. , A "No" button 622 pressed by user d, and a "Cancel" button 623 pressed by user d if this user d withholds approval or rejection. When the terminal name of the requesting terminal is displayed, the additional approval request information transmitted in step S45 includes the terminal name of the requesting terminal in addition to the communication ID of the requesting terminal. In this case, as the terminal name of the requesting terminal, the corresponding terminal name is also extracted when the operating state is confirmed in step S44.

Next, when the user d presses any of the "Yes", "No", or "Cancel" buttons on the additional request reception screen shown in FIG. 11, the operation input reception unit 12 is set to "Yes", "No", or "Cancel", respectively. Accepts "approve", "reject", or "hold" instructions (step S46-5). Then, the process returns to step S46-2, and the process is repeated by trying to extract the communication ID of the remaining requesting terminal stored in the volatile storage unit 2000. Then, when the communication IDs of all the requesting terminals are extracted as "01aa" (steps 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 10dc) transmits additional request response information indicating an approval, rejection, or hold additional request response 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 additional request response indicates "approval" will be described subsequently.

Next, the additional request management unit 59 sets 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 to 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 requesting terminal in the same destination list management DB 3002 as the ID "01aa" (step S48).

If the additional request response indicates "rejected", 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. Further, when the additional request response indicates "pending", 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 in.

Next, the terminal extraction unit 54 searches the terminal management DB 3004 based on the communication ID "01aa" of the requesting terminal and the communication ID "01dc" of the requesting destination terminal, and thereby, each corresponding information (destination name, The operating state) is extracted (step S49).

Then, the transmission / reception unit 51 transmits additional completion information to the request source terminal (transmission terminal 10aa) and the request destination terminal (transmission terminal 10dc), respectively (steps S50-1 and 2). Of 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 each information (communication ID, destination name, and operation) of the request destination terminal (transmission terminal 10dc). State) is included. That is, only each 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.
