Japanese Patent Laid-Open No. 8-018676

  With the technology described in Patent Document 1, if an individual call is made with a specific conference participant during an audio conference, the content of the audio conference cannot be heard during that time. In addition, when a call for inviting a conference is received from the conference call device during an important phone call with a business partner or the like, it is necessary to terminate the call during the call.

  The object of the present invention has been made in view of the above circumstances, and enables voice calls with other conference participants or non-participants during an audio conference and listens to received voices during and during the conference. It is another object of the present invention to provide a telephone device that transmits transmitted voice during a call only to the other party.

  The above-described problem is that the first received voice signal receiving means for receiving a received voice signal from the first communication apparatus and the received voice signal from the second communication apparatus have a call function with a plurality of communication apparatuses. Second received voice signal receiving means for receiving, received voice signal synthesis for synthesizing the first voice signal received by the first received voice signal receiving means and the second voice signal received by the second received voice signal receiving means. Means, a received voice output means for converting a received voice signal into a voice and outputting it, a transmitted voice input means for converting a transmitted voice into a voice signal, and a transmitted voice input by the transmitted voice input means Transmission voice signal switching transmission means for switching and transmitting the signal to either the first communication device or the second communication device, and during the call with the first communication device, the second communication When there is an incoming call from the device or to the second communication device When there is a call, the reception voice output means converts the reception voice signal synthesized by the reception voice signal synthesis means into a voice and outputs it, and the transmission voice signal switching transmission means sends the transmission voice input by the transmission voice input means. This can be achieved by a telephone device that switches to transmit a speech signal to the second communication device.

  According to the present invention, since the voice of the audio conference can be heard even when a voice call is performed with another call partner during the audio conference, the state of the audio conference can be easily understood and the user can easily return to the audio conference.

Hereinafter, embodiments of the present invention will be described with reference to the drawings using examples. Note that the same reference numerals are used for substantially the same parts, and description thereof will not be repeated.
First, a telephone system will be described with reference to FIG. Here, FIG. 1 is a connection configuration diagram of a telephone system including a telephone device having a function of calling with a plurality of parties. In FIG. 1, a telephone device 200 having a call function with a plurality of parties is connected to a LAN line 700 to which a router (or gateway) 600 connected to an IP network 100 is connected. The IP network 100 is connected to a multipoint connection unit (MCU: Multipoint Control Unit) 400 that realizes a conference call and an IP device 300-1 and 300-2 that performs a conference call with a SIP server 500, and further performs a non-conference call. The IP device 300-3 to be performed is also connected.

  The telephone device 200 performs a telephone conference with the plurality of IP devices 300-1 and 300-2 by the following procedure. First, the telephone device 200 makes a call to the SIP server 500 in order to connect to the MCU 400. The SIP server 500 connects to the MCU 400 and establishes a voice communication path between the telephone device 200 and the MCU 400.

  Similarly, the IP device 300-1 and the IP device 300-2 make a call to the SIP server 500 to connect to the MCU 400, connect to the MCU 400, and connect the voice communication path between the MCU 400 and the IP device 300-1. Between the MCU 400 and the IP device 300-2.

  The MCU 400 mixes (synthesizes) voices of the connected telephone device 200, the IP device 300-1, and the IP device 300-2 to realize a conference call by a plurality of parties. If there is an incoming call from the IP device 300-3 to the telephone device 200 during the conference call, the telephone device 200 receives the incoming call from the SIP server 500. The telephone device 200 accepts an incoming call from the IP device 300-3 and makes a call while continuing the conference call between the IP device 300-1 and the IP device 300-2.

  At this time, the telephone device 200 receives the voice of reception from the MCU 400 but does not transmit the voice of transmission of the telephone device 200 to the MCU 400. As a result, the telephone device 200 transmits to the IP device 300-3 that has received the incoming call, and does not transmit to the IP device 300-1 and the IP device 300-2 connected to the MCU 400. For this reason, the voice of the telephone device 200 cannot be heard by the IP device 300-1 and the IP device 300-2. However, since the telephone device 200 receives the voice of the incoming call from the MCU 400, the voice of the IP device 300-1 and the IP device 300-2 can be heard even when a call is made with the IP device 300-3. You can easily return to the conference call.

  With reference to FIG. 2, the telephone apparatus which has a telephone call function with a some other party is demonstrated. Here, FIG. 2 is a functional block diagram of the telephone device. 2, the telephone device 200 includes a key input unit 401, a conference call registration processing unit 402, a participant table 403, a main control unit 404, a voice call switching notification unit 405, a voice direction notification unit 406, Display unit 407, two received voice signal reception processing unit 408, received voice synthesis unit 410, received level adjustment unit 411, received voice output unit 412, transmitted voice input unit 413, and transmitted voice switching unit 414, an RTP processing unit 415, an SIP processing unit 416, a TCP / UDP / IP processing unit 417, and an Ethernet (registered trademark) processing unit 418.

  The key input unit 401 has a function for switching to an IP device or an incoming call response and a function for switching the voice of a transmission during a conference call, and notifies the main control unit 404 of key operation information. The key input unit 401 further notifies the key operation information to the voice call switching notification unit 405.

  The telephone conference registration processing unit 402 registers the other party's IP device as a telephone conference terminal in response to an instruction from the main control unit 404. The registered IP device is stored as a participant table 403.

  The main control unit 404 determines the information notified from the key input unit 401 and the transmission state or the incoming state, and changes the state. Also, instructions such as voice switching and voice level adjustment are given, and instructions for displaying the voice transmission direction are given. The voice call switching notification unit 405 notifies the main control unit 404 of a call switching instruction with another telephone during a call with a plurality of telephones.

  In response to an instruction from the main control unit 404, the voice direction notifying unit 406 transmits the voice to the conference call of the MCU 400 or transmits the voice to the IP device 300-3 that performs the non-conference call. Display data is generated and transmitted to the display unit 407. The display unit 407 displays on the LCD or the like in order to display that a call is being made with another non-conference partner during a conference call with a plurality of other parties.

  The received voice signal reception processing unit 408-1 receives the received voice signal from the other party of the telephone conference or the first party of the non-telephone conference, and transmits it to the received voice synthesis unit 410. The received voice signal reception processing unit 408-2 receives the received voice signal from the other party of the telephone conference or the second party of the non-telephone conference, and transmits it to the received voice synthesis unit 410.

  Here, the first partner is a partner who performs a conference call between the IP device 300-1 and the IP device 300-2. The second partner is the IP device 300-3 that performs a non-conference call. The received voice synthesizing unit 410 has a function of mixing voices from the first partner and voices from the second partner and performing voice synthesis. The synthesized voice is notified to the received voice output unit 412.

  In response to an instruction from the main control unit 404, the reception level adjustment unit 411 lowers the signal level of the reception voice from the other party not transmitting the transmission voice to the reception voice synthesis unit 410.

  The received voice output unit 412 D / A converts the received voice signal into voice and outputs the voice. The transmitted voice input unit 413 inputs A / D converted voice signals into voice signals. The transmission voice switching unit 414 transmits the voice input from the transmission voice input unit 413 while switching the transmission voice signal to either the first partner or the second partner under the control of the main control unit 404.

  The RTP processing unit 415 forms an IP packet from the voice data. The RTP processing unit 415 also forms voice data from the IP packet. The SIP processing unit 416 controls sequences such as outgoing and incoming calls for making a call. The TCP / UDP / IP processing unit 417 transmits and receives the IP packet formed by the RTP processing unit 415 or the SIP processing unit 416 as a protocol. The Ethernet processing unit 418 transmits and receives IP packets to and from the LAN network 700.

  With reference to FIG. 3, a sequence for explaining an operation of performing a non-conference call during a conference call by a telephone device having a call function with a plurality of opponents will be described. FIG. 3 is a sequence diagram among the MCU, the SIP server, the telephone device, and a plurality of IP devices. In FIG. 3, the telephone device 200 makes a call to the SIP server 500 to make a conference call (S501). The SIP server 500 connects to the MCU 400 (S502). The MCU 400 returns a response to the telephone device 200 (S503). As a result, a call path is established and the telephone device 200 and the MCU 400 enter a call state.

  Next, the IP device 300-1 makes a call to the SIP server 500 in order to make a conference call (S505). The SIP server 500 connects to the MCU 400 (S506). The MCU 400 returns a response to the IP device 300-1 (S507). As a result, a call path is established and the IP device 300-1 and the MCU 400 are in a call state.

  Further, the IP device 300-2 makes a call to the SIP server 500 in order to make a conference call (S509). The SIP server 500 connects to the MCU 400 (S510). The MCU 400 returns a response to the IP device 300-2 (S511). As a result, a call path is established and the IP device 300-2 and the MCU 400 are in a call state.

  The MCU 400 synthesizes voices of the telephone device 200, the IP device 300-1, and the IP device 300-2, and transmits the synthesized speech to the telephone device 200, the IP device 300-1, and the IP device 300-2, thereby allowing a conference by three parties. It becomes a call state.

  An incoming call from the IP device 300-3 to the telephone device 200 as a second call when in a conference state will be described. The IP device 300-3 performs a call operation to the SIP server 500 in order to make a call to the telephone device 200 (S513). The SIP server 500 receives an incoming call to the telephone device 200 (S514). The telephone device 200 transmits a response to the IP device 300-3 (S515). The telephone device 200 switches the transmission voice transmitted to the MCU 400 by the transmission voice switching unit 414 (S516), and transmits the voice to the IP device 300-3. The telephone device 200 and the IP device 300-3 make a call. It becomes a state.

  The IP device 300-1 continues to talk with the MUC 400, and the IP device 300-2 also keeps talking to the MUC 400. Therefore, the conference call continues. The telephone device 200 lowers the level of the first voice of the IP device 300-1 and the IP device 300-2 sent from the MCU 400 from the second voice of the IP device 300-3 by controlling the reception level adjustment unit 411. Control is performed (S520). As a result, the voices received by the IP device 300-1 and the IP device 300-2 from the MCU 400 are reduced, and the voices received from the IP device 300-3 are easy to hear. Here, a one-way arrow from the MCU 400 to the telephone device 200 indicates a one-way transmission.

  When returning to the conference call, in response to the switching operation of the telephone device 200, the transmission voice transmitted to the IP device 300-3 by the transmission voice switching unit 414 is switched to the MCU 400 (S522). A conference call between the IP device 300-1 and the IP device 300-2 can be performed via the MCU 400. IP device 300-1 and MCU 400 continue to talk, and IP device 300-2 and MCU 400 also continue talking. Therefore, the first call that is a conference call and the second call that is a non-conference call can be freely switched without terminating the conference call. By switching to the first call, the voice level of the incoming call from the IP device 300-3 can be lowered (S526), and the conference call can be performed while receiving the voice from the IP device 300-3. Here, a one-way arrow from the IP device 300-3 to the telephone device 200 indicates a one-way transmission.

With reference to FIG. 4, the operation of the telephone device having a call function with a plurality of opponents will be described. Here, FIG. 4 is an operation flowchart of the telephone device. In FIG. 4, the telephone device 200 determines a call operation, an incoming call operation, and a voice output switch by the key input unit 401 by a key operation (S601) (S602, S613, S624). In addition, the main control unit 404 monitors whether or not a call is in progress (S623).
In the case of outgoing (Yes in S602), the main control unit 404 determines whether the outgoing call is a conference (S603). If it is a conference call (Yes in S603), the main control unit 404 sends the call to the MCU 400 via the SIP server 500 (S604). After waiting for a response from the MCU 400 for a while, the main control unit 404 determines the response (S605). If there is no response (No in S605), the main control unit 404 enters a standby state.

  If there is a response (Yes in S605), the telephone device 200 is in a voice call with the MCU 400 (S606). The telephone conference registration processing unit 402 of the telephone device 200 receives the conference participant information from the MCU 400 (S607) and stores it in the participant table 403 (S608). The participant table 403 recognizes whether the IP device that is making a call is a conference call or a non-conference call. use. The telephone device 200 displays from the voice direction notification unit 406 that the call direction is to the MCU 400 (S609), and enters a standby state (waiting for key operation).

When the call from the telephone device 200 is a call to a non-conference call (No in S603), the main control unit 404 makes a call to the IP device as a non-conference call (S610). After waiting for a response from the counterpart IP device for a while, the main control unit 404 determines the response (S611). If there is a response (Yes in S611), the main control unit 404 determines whether a conference call is in progress (S616). If the conference call is in progress (Yes in S616), the transmission voice switching unit 414 switches the transmission to the IP device 300-3 that has received the voice call with the MCU 400 (S617). Subsequently, the received voice from the MCU 400 and the received voice from the IP device 300-3 are synthesized by the received voice synthesis unit 410 (S618). Then, the main control unit 404 controls the reception level adjustment unit 411 to lower the level of the reception voice from the MCU 400 (S619). Since the transmission direction of the telephone device 200 is the IP device 300-3 that responds to the incoming call, the transmission direction is controlled by the display unit 407 to display that the transmission is to the IP device 300-3 ( S620). Then, it is displayed that the first call of the conference call and the second simultaneous call of the non-conference call (S621). The telephone device 200 and the IP device 300-3 enter a voice call state (S622), and the main control unit 404 enters a standby state. If the plurality of telephone conversations are not being performed (No in S616), the main control unit 404 proceeds to step 622 as it is.
When there is no response (No in S611), the main control unit 404 is in a standby state as it is.

  When an incoming operation is performed at the key input unit 401 by key operation (S601) of the telephone device 200 (No at S602 and Yes at S613), the main control unit 404 displays an incoming call on the display unit 407 (S614). After answering the incoming call (S615), the process proceeds to step 616.

  When the key operation (S601) performs an operation other than the outgoing call operation and the incoming call operation (No in S602 and No in S613), the main control unit 404 determines whether a call is in progress (S623). When the call is in progress (Yes in S623), the main control unit 404 determines whether the key operation in Step 601 is switched (S624). If yes, the process proceeds to step 616. When the main controller 404 is No in step 624, the main controller 404 enters a standby state.

  When No in step 623, the main control unit 404 determines whether a plurality of calls are finished (S625). When Yes, the main control unit 404 cancels the simultaneous call (S626) and transitions to a standby state. On the other hand, when the result is No in step 625, the state transits to the standby state as it is.

  To switch the transmission voice, when a specific key (for example, # key) is pressed during a call with the second call partner, the transmission is switched from the second call partner to the first call partner. Further, when a specific key is continuously pressed, the transmission is temporarily switched from the call with the second call partner to the first call partner, and the first call partner can be talked to. At this time, if the pressing of a specific key is stopped, the direction of the transmission can be returned to the second calling party who was talking.

  Further, the other party of the first call may be a general call instead of the MCU 400, and a plurality of calls may be made with a call made to the MCU 400 or a call from the MCU 400 during the general call as a second call.

  The embodiment of the telephone device having a call function with a plurality of opponents according to the present invention has been described above. However, the telephone device 200 may be a telephone device with an MCU, and the IP device 300-1 and the IP device 300 that perform a conference call. -2 may also be the telephone device of this embodiment.
