<< Overall configuration of communication system >>
First, a communication system 1 for performing a video conference between a plurality of communication terminals 10 and 70 will be described with reference to FIG. FIG. 1 is a schematic diagram showing a communication part of a video conference in the communication system of the present embodiment.

  It is sometimes called “video conference” instead of “video conference”. Further, here, a video conference will be described as an example, but it may be a simple conversation.

  The communication system 1 is constructed by a plurality of communication terminals 10 and 70, a relay device 30, and a communication management 50. The communication terminals 10 and 70 perform communication by transmitting and receiving image data and sound data as an example of content data. In FIG. 1, a video conference terminal is shown as an example of the communication terminal 10, and an electronic blackboard is shown as an example of the communication terminal 70. The image of the image data may be a moving image or a still image, or both a moving image and a still image.

  Further, a communication terminal as a request source requesting the start of a video conference is represented as “request source terminal”, and a communication terminal as a request destination (relay destination) is represented as “destination terminal”. In FIG. 1, the communication terminal 10 is represented as a request source terminal, and the communication terminal 70 is represented as a destination terminal. However, when requesting the start of a video conference from the communication terminal 70, the communication terminal 70 becomes a request source terminal and the communication terminal 10 becomes a destination terminal. In addition, each communication terminal 10 and 70 is not only communication between several offices, communication between different rooms in the same office, but also communication in the same room, outdoor and indoor or outdoor and outdoor. May be used in communication.

  The relay device 30 performs processing for relaying content data between the plurality of communication terminals 10 and 70. The communication management system 50 centrally manages login authentication from the communication terminals 10 and 70, management of the communication status of the communication terminals 10 and 70, management of the destination list, communication status of the relay device 30, and the like. The relay device 30 and the communication management system 50 may be constructed by a single computer, or may be constructed by a plurality of computers arbitrarily assigned by dividing each unit (function or means). .

  In the communication system 1, a management information session sei for transmitting and receiving various types of management information is established between the request source terminal and the destination terminal via the communication management system 50. Further, between the request source terminal and the destination terminal, four pieces of data of high resolution image data, medium resolution image data, low resolution image data, and sound data are transmitted and received via the relay device 30. Four sessions are established. In FIG. 1, these four sessions are collectively shown as an image / sound data session sed. Note that the image / sound data session sed does not necessarily have to be four sessions, and may have a smaller or larger number of sessions than the four sessions. Further, a communication session may be established directly between the request source terminal and the destination terminal without using the relay device 30.

  Here, the resolution of the image data handled in the present embodiment will be described. The low-resolution image data includes, for example, 160 pixels in the horizontal direction and 120 pixels in the vertical direction, and becomes a base image. The medium resolution image data consists of 320 pixels in the horizontal direction and 240 pixels in the vertical direction. The high-resolution image data includes, for example, 640 pixels in the horizontal direction and 480 pixels in the vertical direction. Among these, when passing through a narrow band route, low-quality image data consisting only of low-resolution image data serving as a base image is relayed. When the band is relatively wide, low-resolution image data serving as a base image and medium-quality image data composed of medium-resolution image data are relayed. When the bandwidth is very wide, high-resolution image data composed of low-resolution image data serving as base image quality, intermediate-resolution image data, and high-resolution image data is relayed. Since the sound data has a smaller data amount than the image data, it is relayed even on a narrow band route.

The terminal authentication is performed by searching and determining whether the same terminal ID and the same password are managed (step S63). Since the same terminal ID and the same password are managed by the storage / reading processing unit 59, it is determined that the login request is from the communication terminal 10 in which the activation application having a valid usage right is installed. In the terminal management table (see FIG. 10), the storage / read processing unit 59 changes the field portion of the operating state of the record of the terminal ID received in step S62 to “ON line (communicable)”. At the same time, the reception date and time when the login request information is received in step S63 is stored in the field of reception date and time (step S64). Thereby, in the terminal management table, the terminal ID “01aa”, the operation state “online (communicable)”, the reception date and time “2015.4.10.13:40”, and the IP address “1.2.1.3” are displayed. "Will be managed in association with each other. Note that the IP address of the terminal is not registered in advance, but may be transmitted from the communication terminal 10aa in step S62.

Destination list request information indicating that a destination list is requested is transmitted to the communication management system 50 (step S66). Thereby, the transmission / reception unit 51 of the communication management system 50 receives the destination list request information.

  Next, the storage / reading processing unit 59 searches the destination list management table (see FIG. 11) using the terminal ID “01aa” of the request source terminal (communication terminal 10aa) that requested the login as a search key, and requests the request source terminal ( The terminal ID of the destination candidate that can communicate with the terminal 10aa) is read out, and the terminal name corresponding to this terminal ID is read out from the terminal management table (see FIG. 10) (step S67). Here, the respective terminal IDs (“01ab”,...) Of the destination candidates (10ab,...) Corresponding to the terminal ID “01aa” of the request source terminal (communication terminal 10aa) and the corresponding destinations. Names (“Japan Tokyo Office AB Terminal”,...) Are extracted.

Thereby, in the request source terminal (communication 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 storage unit 1000 (step S70).

  As described above, in this embodiment, instead of managing the destination list information in each communication terminal, the communication management system 50 centrally manages the destination list information of all the communication terminals. Therefore, a new communication terminal is included in the communication system 1, a new model communication terminal is included instead of the communication terminal already included, or the appearance of the destination list frame is changed. In this case, since the communication management system 50 handles all at once, it is possible to save the trouble of changing the destination list information on each communication terminal side.

  Further, the storage / reading processing unit 59 of the communication management system 50 searches the terminal management table (see FIG. 10) using the terminal ID (“01ab”,...) Of the above-mentioned read destination candidate as a search key, By reading out the corresponding operating state for each terminal ID, each operating state of the communication terminal (10ab,...) As a destination candidate is acquired (step S71).

  Next, the transmission / reception unit 51 transmits “terminal operation status information” including each terminal ID as a search key used in step S67 and the operation status of each corresponding destination terminal to the communication network 2. To the request source terminal (communication terminal 10aa) (step S72).

  Next, the storage / read processing unit 19 of the request source terminal (communication terminal 10aa) sequentially stores the terminal status information received from the communication management system 50 in the storage unit 1000 (step S73). Therefore, the request source terminal (communication terminal 10aa) receives the current status information of each communication terminal, so that the current terminal such as the communication terminal 10ab which is a destination candidate capable of communicating with the request source terminal (communication terminal 10aa). Each operating state can be acquired.

  Next, the display control unit 14 of the request source terminal (communication terminal 10aa) reflects the state of the communication terminal as a destination candidate based on the destination list information stored in the storage unit 1000 and the terminal state information. The display control unit 14 displays the destination list shown in FIG. 19 on the display 120 shown in FIG. 2 (step S74). An icon indicating the operating state is shown at the left end of each destination. In FIG. 19, the icons indicating the operating states of the communication terminals are “online (communication possible)”, “offline”, “online (communication possible)”, and “online (during communication)” from the top. Show.

  On the other hand, the storage / read processing unit 59 of the communication management system 50 searches the destination list management table (see FIG. 11) based on the terminal ID “01aa” of the request source terminal (communication terminal 10aa) that has requested login. Then, the terminal IDs of other request source terminals that register the terminal ID “01aa” of the request source terminal (communication terminal 10aa) as destination candidates are extracted (step S75). In the destination list management table shown in FIG. 11, the terminal IDs of other start request source terminals to be read are “01ab”, “07db”, and the like.

  Next, the storage / read processing unit 59 of the communication management system 50 searches the terminal management table (see FIG. 10) based on the terminal ID “01aa” of the request source terminal (communication terminal 10aa) that has made the login request. Then, the operating state of the request source terminal (communication terminal 10aa) that has requested the login is acquired (step S76).

  The transceiver 51 operates in the terminal management table (see FIG. 10) among the communication terminals (10ab, 70db,...) Related to the terminal ID (“01ab”, “07db”, etc.) extracted in step S75. The communication terminal (10ab,...) Whose status is “online” includes the terminal ID “01aa” of the request source terminal (communication terminal 10aa) acquired in step S76 and the operation status “online”. State information "is transmitted (step S77). When the transmitting / receiving unit 51 transmits the terminal status information to the communication terminal (10ab,...), It is managed in the terminal management table (see FIG. 10) based on each terminal ID (“01ab”,...). Refers to the IP address of the communication terminal. Thereby, the terminal of the request source terminal (communication terminal 10aa) that requested the login to each of the other destination terminals (10ab,...) That can communicate with the request source terminal (communication terminal 10aa) that requested the login as a destination candidate. The ID “01aa” and the operation state “online” can be transmitted. Thereby, also in the destination candidate (communication terminal 10ab), the status of the destination candidate as shown in FIG. 18 can be displayed (step S78).

  Next, a case where the communication terminal 10 acquires terminal identification information for specifying the communication terminal 70db from the mobile terminal 90a will be described using FIG. 20 and FIG. FIG. 20 is a sequence diagram illustrating terminal identification information acquisition processing. FIG. 21 is a flowchart showing destination specifying processing.

  First, in a state where the destination list shown in FIG. 19 is displayed on the display 120, the user X at the site A brings the mobile terminal 90 a close to the communication terminal 10. On the other hand, in the communication terminal 10aa, the determination unit 15 determines whether or not the mobile terminal 90a is in proximity (step S81). Hereinafter, a case where the user X brings the mobile terminal 90a close to the communication terminal 10 will be described.

  The acquiring / providing unit 98a of the communication terminal 10aa transmits a terminal identification information read request to the mobile terminal 90a by short-range wireless communication (step S82). On the other hand, the storage / reading processing unit 99a of the mobile terminal 90a reads the terminal identification information (here, the terminal ID) of the communication terminal 70db from the storage unit 9000a (step S83).

  Next, the acquiring / providing unit 98a transmits the terminal ID to the communication terminal 10aa by short-range wireless communication (step S84). Thereby, the acquisition / providing unit 18 of the communication terminal 10aa acquires the terminal ID. Then, the storage / reading processing unit 19 stores the terminal ID in the storage unit 1000 (step S85).

  Next, the communication terminal 10aa performs a process of specifying a destination using the terminal identification information (here, the terminal ID) received in step S85 (step S86). Here, the processing in step S86 will be described in detail with reference to FIG.

  As illustrated in FIG. 21, the selection unit 16 selects a communication application to be activated based on the terminal identification information (step S86-1). Here, since the terminal identification information is the terminal ID, the communication application A1 that requires the terminal ID to start communication is selected. And starting part 17 starts communication application A1 (Step S86-2).

  Next, the storage / reading processing unit 99a searches the destination list information stored in the storage unit 1000 in step S70 using the terminal ID received in step S84 as a search key (step S86-3). If it is determined in step S86-3 that it is included in the destination list information (YES), the process proceeds to step S121 described later. On the other hand, if it is determined in step S86-4 that it is not included in the destination list information (NO), the process proceeds to step S101.

  Next, destination list addition processing will be described with reference to FIGS. 22 and 23. FIG. 22 is a sequence diagram showing an addition process to the destination list. FIG. 23 is a diagram showing an example of a screen when adding approval to the destination list.

  Here, a case will be described in which the communication terminal 10aa makes an approval request for adding the communication terminal 70db to the destination list of the communication terminal 10aa to the communication terminal 70db. Here, the communication terminal 10aa is a “request source terminal”, and the communication terminal 70db is a “request destination terminal”.

  First, the transmission / reception unit 11 of the request source terminal (communication terminal 10aa) transmits addition request information indicating a request for adding a destination candidate to the communication management system 50 via the communication network 2 (step S101). This additional request information includes a terminal ID for identifying the request source terminal (communication terminal 10aa) and a terminal ID “07db” for identifying the request destination terminal (communication terminal 70db). Thereby, the transmission / reception unit 51 of the communication management system 50 receives the addition request information.

  Next, in the communication management system 50, the storage / read processing unit 59 adds the received terminal ID of the request source terminal to the terminal ID field of the request source terminal of the new record in the additional request management table (see FIG. 12). “01aa” is stored and managed, and the terminal ID “07db” of the request destination terminal is additionally stored and managed in the terminal ID field of the request destination terminal of the new record (step S102).

  Next, the determination unit 52 determines the corresponding operation state by searching the terminal management table (see FIG. 10) based on the terminal ID “07db” of the request destination terminal (step S103). If the determination unit 52 determines that the operating state is online but communication has not started, the transmission / reception unit 51 continues to send the request for addition to the request destination terminal (communication terminal 70db). The additional approval request information indicating a request to approve or not is transmitted (step S104). This additional approval request information includes the terminal ID “01aa” of the request source terminal. Thereby, the transmission / reception unit 71 of the request destination terminal (communication terminal 10db) receives the additional approval request information.

  Next, in the request destination terminal (communication terminal 70db), the display control unit 74 displays an additional request response screen as shown in FIG. 23 on the display 753 (step S105).

  Next, the transmission / reception unit 71 of the request destination terminal (communication terminal 70db) transmits additional request response information indicating an additional request response of approval, rejection or suspension to the communication management system 50 (step S106). When the user D approves, the “YES” button on the addition request response screen is pressed. When the user D rejects, the “NO” button on the addition request response screen is pressed. When the user D holds, the “CANCEL” button on the addition request response screen is pressed. Thereby, the transmission / reception unit 51 of the communication management system 50 receives the additional request response information. Here, the case where the addition request response indicates “approval” will be described.

  The storage / reading processing unit 59 requests the terminal ID “07db” of the request destination terminal associated with the terminal ID “01aa” of the request source terminal in the additional request management table (see FIG. 12). Management is additionally performed in association with the terminal ID “01aa” of the request source terminal in the same destination list management table as the terminal ID “01aa” of the original terminal (step S107).

  If the additional request response indicates “reject”, in step S107, the storage / reading processing unit 59 determines that the terminal ID “rejected” in the additional request management table (see FIG. 12). The record “01aa” is deleted. If the additional request response indicates “hold”, the storage / reading processing unit 59 does not perform additional management in step S107, and records in the additional request management table (see FIG. 12). Do not delete it.

  Next, the storage / read processing unit 59 searches the terminal management table (see FIG. 10) based on the terminal ID “01aa” of the request source terminal and the terminal ID “07db” of the request destination terminal, thereby corresponding to each. Are read (destination name, operating state) (step S108). Then, the transmission / reception unit 51 transmits the addition completion information to the request source terminal (communication terminal 10aa) and the request destination terminal (communication terminal 70db), respectively (steps S109-1, 2). Among these, the addition completion information transmitted to the request source terminal (communication terminal 10aa) includes a message indicating that the addition has been completed, and information (terminal ID, destination name, and operation) of the request destination terminal (communication terminal 70db). State). That is, only the information (terminal ID, destination name, and operating status) of the request destination terminal (communication terminal 70db) portion in the destination list is transmitted to the request source terminal (communication 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 (communication terminal 70db) includes a message indicating that the addition is completed, and each piece of information (terminal ID, destination name, and operation) of the request source terminal (communication terminal 10aa). State).

  In the request source terminal (communication terminal 10aa), the display control unit 14 displays a screen indicating completion on the display 120 (step S110-1). On the other hand, in the request destination terminal (communication terminal 70db), the display control unit 74 displays a screen indicating completion on the display 753 (step S110-2). On the communication management system 50 side, when the processing in steps S110-1 and S110-2 is completed, the storage / reading processing unit 59 uses the terminal ID “of the request destination terminal approved in the additional request management table (see FIG. 12). By deleting the record “07db”, all the processes of the destination candidate addition request are completed (step S111). Thereafter, the process of step 121 described later is automatically started.

  Next, a process for preparing for image / sound communication using the communication system will be described with reference to FIG. FIG. 24 is a sequence diagram showing processing for preparing for image / sound communication using the communication system.

  When it is determined in step 86-4 in FIG. 21 that the terminal ID is included in the destination list information (YES), the user X has to bother to select the communication terminal 70db from the destination list in FIG. The request source terminal (communication terminal 10aa) automatically transmits start request information indicating a communication start request to the communication management system 50. Specifically, the transmission / reception unit 11 transmits communication start request information to the communication management system 50 via the communication network 2 (step S121). This start request includes the terminal ID “01aa” of the request source terminal (communication terminal 10aa) and the terminal ID “07db” of the destination terminal (communication terminal 70db). Thereby, the transmission / reception unit 51 of the communication management system 50 receives the communication start request.

  Next, the storage / read processing unit 59 of the communication management system 50 sets the terminal ID “01aa” of the request source terminal (communication terminal 10aa) and the terminal ID “07db” of the destination terminal (communication terminal 70db) included in the start request. Based on the terminal management table (see FIG. 10), both the field portions of the operating state of the records each including the terminal ID “01aa” and the terminal ID “07db” are changed to “busy” (step S122). . In this state, the request source terminal (communication terminal 10aa) and the destination terminal (communication terminal 70db) have not started a video conference, but are in a communication state and other communication terminals are requested by the request source terminal (communication terminal). 10aa) or a destination terminal (communication terminal 70db), a notification sound or display indicating a so-called communication state is output.

  Next, the storage / reading processing unit 59 of the communication management system 50 uses the terminal IDs of the request source terminal (communication terminal 10aa) and the destination terminal (communication terminal 70db) received by the process of step S121 as search keys. Each corresponding IP address is read by searching the terminal management table (see FIG. 10) (step S123).

  Then, the transmission / reception unit 51 of the communication management system 50 transmits communication start request information to the IP address of the destination terminal (communication terminal 70db) read in step S123 (step S124). This start request information includes the terminal IDs “01aa” and “07db” received by the process of step S121. Thereby, the transmission / reception unit 71 of the destination terminal (communication terminal 70db) receives the start request information.

  In response to this, the transmission / reception unit 71 of the destination terminal (communication terminal 70db) transmits response availability information indicating availability of response to the communication management system 50 (step S125). Thereby, the transmission / reception unit 51 of the communication management system 50 receives the response availability information. The response availability information indicates that communication is possible or impossible, but here, a case where communication is possible will be described.

  The transmission / reception unit 51 of the communication management system 50 transmits relay start request information to the relay device 30 (step S126). This start request information includes each IP address read out by the process of step S123. As a result, the transmission / reception unit 31 of the relay device 30 receives the relay start request information.

  Further, the transmission / reception unit 51 of the communication management system 50 transmits the response availability information received in the process of step S125 to the request source terminal (communication terminal 10aa) (step S127). Thereby, the transmission / reception unit 11 of the request source terminal (communication terminal 10aa) receives the response availability information (here, communication is possible).

  Thus, the image / sound communication session (second communication session) is established between the request source terminal (communication terminal 10aa), the relay device 30, and the destination terminal (communication terminal 70db) (steps S128-1 and S128-2). Thus, the communication terminals 10aa and 70db) can start a video conference call at two locations.

<< Main effects of this embodiment >>
As described above, according to the present invention, identification information (terminal ID or the like) is acquired from the mobile terminal 90d of the user Y by the mobile terminal 90a of the user X, and this identification information is transmitted to the communication on the user X side.

  Conventionally, when the communication terminals 10 and 70 have a plurality of communication applications A1, A2 and A3, in order for the communication terminal 10 to communicate with the communication terminal 70 (the other party), due to a difference in communication protocol, A terminal ID, an IP address, an e-mail address, or the like must be input or selected to the communication terminal 10 on the self side as terminal identification information for identifying the communication terminal 70. On the other hand, the communication terminal 10 of the present embodiment may be activated to activate a specific communication application based on the description format of the terminal identification information of the communication terminal 70 among the plurality of communication applications A1, A2, and A3. In addition, the communication terminal 70 as the communication destination on the communication network 2 can be identified (see S86-3). As a result, it is possible to solve the problem that it takes time to start communication.

  Furthermore, conventionally, when the communication terminal 10 communicates with the communication terminal 70, the user X has selected the terminal identification information of the communication terminal 70 from the destination list. However, when terminal identification information of a large number of communication terminals is managed in the destination list, it takes time to select, so it takes time to start communication. On the other hand, the communication terminal 10 according to the present embodiment is configured such that the mobile terminal 90a that has received the terminal identification information that the mobile terminal 90d that has acquired the terminal identification information from the communication terminal 70 has transmitted using the first communication session. From this, the terminal identification information is acquired, and the communication terminal 70 specified by the acquired terminal identification information is processed to start communication using the second communication session (see S61). As a result, the user X does not have to select the terminal identification information even when the terminal identification information of a large number of communication terminals is managed in the destination list. The time until the start can be shortened.
