For example, some enterprises and individuals usually need to record the calls of specific users based on the needs of supervision and recording.
请参考图1，现有技术中的通话录音系统中通常包含呼叫控制服务器（CallControl Manager）、录音服务器（Recording Server）、媒体控制单元（Multipoint ControlUnit，MCU）及终端（User Equipment，UE）。UE1与UE2之间要实现点对点的通话录音，需要通过呼叫控制服务器在MCU上创建会场，通话的双方UE1、UE2和录音服务器都要加入到会场中。在通话录音时MCU会将UE1和UE2发送的数据进行混音后发送给录音服务器。Please refer to FIG. 1 , the call recording system in the prior art usually includes a call control server (CallControl Manager), a recording server (Recording Server), a media control unit (Multipoint ControlUnit, MCU) and a terminal (User Equipment, UE). To realize point-to-point call recording between UE1 and UE2, a conference site needs to be created on the MCU through the call control server, and both parties in the call, UE1, UE2, and the recording server, must join the conference site. When recording a call, the MCU will mix the data sent by UE1 and UE2 and send it to the recording server.
由于现有技术的通话录音需要创建会场并通过MCU进行混音，因此需要占用MCU的媒体资源，可见现有技术在进行通话录音时存在占用MCU的媒体资源的技术问题。Since the call recording in the prior art needs to create a conference site and perform audio mixing through the MCU, it needs to occupy the media resources of the MCU. It can be seen that there is a technical problem of occupying the media resources of the MCU in the call recording in the prior art.

Wherein, the first terminal is used to send media to the second multicast group where the second terminal is located, and the second terminal is used to send media to the first multicast group where the first terminal is located; the call control server is used to implement call signaling processing and service control, responsible for managing the user's recording authority and recording business process negotiation; the recording server and the call control server can be connected through the Web Service interface, and are used to join the first multicast group and the second multicast group to receive and Record the media sent by the first terminal and the second terminal; the router is used to copy and forward the media sent by the first terminal and the second terminal.
请参考图3，对应该录音系统本申请实施例提供第一种录音方法，应用于呼叫控制服务器。第一种录音方法可以应用于第一终端未开启自动录音业务的场景中。具体的，第一种录音方法包括：Please refer to FIG. 3 , corresponding to the recording system, this embodiment of the present application provides a first recording method, which is applied to a call control server. The first recording method may be applied in a scenario where the automatic recording service is not enabled on the first terminal. Specifically, the first recording method includes:
S301：所述呼叫控制服务器接收与第二终端进行通信的第一终端发送的录音请求；S301: The call control server receives a recording request sent by the first terminal communicating with the second terminal;
S302：所述呼叫控制服务器为所述第一终端分配第一组播组地址，通知所述第一终端加入所述第一组播组地址对应的第一组播组，并向所述第二终端发送所述第一组播组地址，以便于所述第二终端向所述第一组播组地址发送用于与所述第一终端通信的媒体；S302: The call control server assigns a first multicast group address to the first terminal, notifies the first terminal to join the first multicast group corresponding to the first multicast group address, and sends the call control server to the second The terminal sends the first multicast group address, so that the second terminal sends media for communicating with the first terminal to the first multicast group address;
S303：所述呼叫控制服务器为所述第二终端分配第二组播组地址，通知所述第二终端加入所述第二组播组地址对应的第二组播组，并向所述第一终端发送所述第二组播组地址，以便于所述第一终端向所述第二组播组地址发送用于与所述第二终端通信的媒体；S303: The call control server assigns a second multicast group address to the second terminal, notifies the second terminal to join the second multicast group corresponding to the second multicast group address, and sends the call control server to the first The terminal sends the second multicast group address, so that the first terminal sends media for communicating with the second terminal to the second multicast group address;
S304：所述呼叫控制服务器将所述第一组播组地址和所述第二组播组地址发送给录音服务器，以使所述录音服务器加入所述第一组播组和所述第二组播组以接收并录制所述第一终端和所述第二终端发送的媒体。S304: The call control server sends the first multicast group address and the second multicast group address to the recording server, so that the recording server joins the first multicast group and the second group broadcast group to receive and record the media sent by the first terminal and the second terminal.
在具体实施过程中，第一终端拨打第二终端的通信号码，通过呼叫控制服务器与第二终端建立通信连接，第一终端与第二终端使用单播通信地址进行通信，即，所述第一终端通过所述第二终端的单播地址（如第二终端的IP地址）向所述第二终端发送媒体，所述第二终端通过所述第一终端的单播地址（如第一终端的IP地址）向所述第一终端发送媒体。In the specific implementation process, the first terminal dials the communication number of the second terminal, establishes a communication connection with the second terminal through the call control server, and the first terminal communicates with the second terminal using a unicast communication address, that is, the first The terminal sends media to the second terminal through the unicast address of the second terminal (such as the IP address of the second terminal), and the second terminal sends media to the second terminal through the unicast address of the first terminal (such as the IP address of the first terminal). IP address) to send media to the first terminal.
请参考图4，在第一终端与第二终端进行通信的过程中，步骤P2：用户1手动启动录音（如点击第一终端界面上的“录音”按钮），触发第一终端向呼叫控制服务器发送录音请求。Please refer to Figure 4. During the communication process between the first terminal and the second terminal, step P2: User 1 manually starts the recording (such as clicking the "recording" button on the interface of the first terminal), triggering the first terminal to call the control server Send a recording request.
在第一终端向呼叫控制服务器发送录音请求后，呼叫控制服务器执行S301接收与第二终端进行通信的第一终端发送的录音请求。呼叫控制服务器在接收到录音请求后将第一终端与第二终端之间的通信方式调整为组播通信。After the first terminal sends the recording request to the call control server, the call control server executes S301 to receive the recording request sent by the first terminal communicating with the second terminal. After receiving the recording request, the call control server adjusts the communication mode between the first terminal and the second terminal to multicast communication.
具体的，呼叫控制服务器将第一终端与第二终端之间的通信方式调整为组播通信，需要在接收第一终端发起的录音请求后，执行S302为第一终端分配第一组播组地址，通知第一终端加入第一组播组地址对应的第一组播组，并向所述第二终端发送所述第一组播组地址，以便于所述第二终端向所述第一组播组地址发送用于与所述第一终端通信的媒体。其中，呼叫控制服务器可以在通知第一终端加入第一组播组的同时向第二终端发送第一组播组地址，也可以在通知第一终端加入第一组播组并确认第一终端已经加入第一组播组后向第二终端发送第一组播组地址。Specifically, the call control server adjusts the communication mode between the first terminal and the second terminal to multicast communication, and needs to execute S302 to assign the first multicast group address to the first terminal after receiving the recording request initiated by the first terminal , notify the first terminal to join the first multicast group corresponding to the first multicast group address, and send the first multicast group address to the second terminal, so that the second terminal can send messages to the first group The broadcast group address sends media used for communicating with the first terminal. Wherein, the call control server may send the first multicast group address to the second terminal while notifying the first terminal to join the first multicast group, or may notify the first terminal to join the first multicast group and confirm that the first terminal has After joining the first multicast group, send the first multicast group address to the second terminal.
在呼叫控制服务器通知第一终端加入第一组播组后，第一终端执行P3：接收呼叫控制服务器通知加入第一组播组的通知消息，加入第一组播组地址对应的第一组播组，并向呼叫控制服务器发送确认消息告知其已加入第一组播组。After the call control server notifies the first terminal to join the first multicast group, the first terminal executes P3: receiving the notification message from the call control server to join the first multicast group, and joins the first multicast corresponding to the first multicast group address group, and send a confirmation message to the call control server to inform it that it has joined the first multicast group.
呼叫控制服务器可以在接收到第一终端的确认消息后，或执行S302的同时执行S303为所述第二终端分配第二组播组地址，通知所述第二终端加入所述第二组播组地址对应的第二组播组，并向所述第一终端发送所述第二组播组地址，以便于所述第一终端向所述第二组播组地址发送用于与所述第二终端通信的媒体。需要说明的是，第一组播组地址和第二组播组地址均由呼叫控制服务器动态分配，并且第一组播组地址和第二组播组地址在录音结束后将被回收再利用，为此有效的提高组播组地址的利用率。The call control server may execute S303 to allocate a second multicast group address for the second terminal after receiving the confirmation message from the first terminal, or execute S302 at the same time, and notify the second terminal to join the second multicast group address corresponding to the second multicast group, and send the second multicast group address to the first terminal, so that the first terminal sends the second multicast group address to the second multicast group address for communicating with the second The medium through which the terminal communicates. It should be noted that both the first multicast group address and the second multicast group address are dynamically assigned by the call control server, and the first multicast group address and the second multicast group address will be recycled and reused after the recording ends. Therefore, the utilization rate of the multicast group address is effectively improved.
相应的，第二终端执行P4：在接收到呼叫控制服务器通知加入第二组播组的通知消息后，加入第二组播组地址对应的第二组播组，并向呼叫控制服务器发送确认消息告知其已加入第二组播组。进一步的，呼叫控制服务器在确认第一终端已加入第一组播组、第二终端已加入第二组播组后，执行S304即P5：将第一组播组地址和第二组播组地址发送给录音服务器，以使录音服务器加入第一组播组和第二组播组以接收并录制第一终端和第二终端发送的媒体。Correspondingly, the second terminal executes P4: After receiving the notification message from the call control server to join the second multicast group, join the second multicast group corresponding to the second multicast group address, and send a confirmation message to the call control server Inform it that it has joined the second multicast group. Further, after confirming that the first terminal has joined the first multicast group and the second terminal has joined the second multicast group, the call control server executes S304, that is, P5: set the address of the first multicast group and the address of the second multicast group to Send to the recording server, so that the recording server joins the first multicast group and the second multicast group to receive and record the media sent by the first terminal and the second terminal.
具体的，录音服务器加入第一组播组和第二组播组后，第二终端执行P6：通过第一组播组地址向第一组播组发送媒体。由于第一组播组中包含组员第一终端和录音服务器，为此路由器收到向第一组播组发送的媒体时将媒体复制转发至第一终端和录音服务器。相应的，第一终端执行P7：通过第二组播组地址向第二组播组发送媒体。也因为第二组播组中包含组员第二终端和录音服务器，路由器收到向第二组播组发送的媒体时将媒体复制转发至第二终端和录音服务器。所以通过将录音服务器加入第一组播组和第二组播组，便可以使录音服务器接收并录制第一终端发送给第二终端的媒体及第二终端发送给第一终端的媒体。可见，通过组播录音不需要在MCU上创建会场节约了媒体资源，并且，通过组播录音也不需要对第一终端发送的媒体和第二终端发送的媒体进行混音，减少了会场混音造成的延时，提升了录音场景下的语音质量。Specifically, after the recording server joins the first multicast group and the second multicast group, the second terminal executes P6: sending media to the first multicast group through the address of the first multicast group. Since the first multicast group includes the first terminal and the recording server of the members, the router copies and forwards the media to the first terminal and the recording server when receiving the media sent to the first multicast group. Correspondingly, the first terminal executes P7: sending media to the second multicast group through the second multicast group address. Also because the second multicast group includes the second terminal and the recording server of the group members, when the router receives the media sent to the second multicast group, it copies and forwards the media to the second terminal and the recording server. Therefore, by adding the recording server to the first multicast group and the second multicast group, the recording server can receive and record the media sent from the first terminal to the second terminal and the media sent from the second terminal to the first terminal. It can be seen that the multicast recording does not need to create a site on the MCU, which saves media resources, and the multicast recording does not need to mix the media sent by the first terminal and the media sent by the second terminal, which reduces the mixing of the site. The delay caused improves the voice quality in the recording scene.
下面通过一完整的实例对上述录音方法进行详细说明，假设第一终端UE1未开启自动录音业务；UE1和第二终端UE2均为注册在呼叫控制服务器下的用户；呼叫控制服务器与录音服务器通过Web Service接口对接。UE1与UE2的录音过程如下：The above-mentioned recording method will be described in detail through a complete example below, assuming that the first terminal UE1 has not started the automatic recording service; both UE1 and the second terminal UE2 are users registered under the call control server; Service interface docking. The recording process of UE1 and UE2 is as follows:
首先，UE1拨打UE2的号码，建立通话。然后，UE1在通话中发起录音请求。呼叫控制服务器在收到UE1发送的录音请求后，为UE1分配组播组地址maddr_1，为UE2分配组播组地址maddr_2，然后，向UE1发送SIP（Session Initiation Protocol，会话初始化协议）Reinvite重邀请消息，并在重邀请消息的SDP（Session Description Protocol，会话描述协议）消息体中携带maddr_2作为UE2的通信地址，在SIP Reinvite消息的头域（如callinfo字段）携带maddr_1以通知UE1加入maddr_1对应的组播组；向UE2发送SIP Reinvite消息，在SIP Reinvite消息的SDP消息体中携带maddr_1作为UE1的通信地址，在SIP Reinvite消息的头域（如callinfo字段）携带maddr_2以通知UE2加入maddr_2对应的组播组。相应的，UE1在接收到该Reinvite消息后，则会加入maddr_1对应的组播组、将maddr_2作为通信对端的通信地址向maddr_2发送媒体，并向呼叫控制服务器发送确认消息告知其已加入maddr_1对应的组播组；UE2在接收到Reinvite消息后，则会加入maddr_2对应的组播组、将maddr_1作为通信对端的通信地址向maddr_1发送媒体，并向呼叫控制服务器发送确认消息告知其已加入maddr_2对应的组播组。接下来，呼叫控制服务器接收UE1和UE2发送的确认消息，并通过Web Service接口通知录音服务器加入第一组播组和第二组播。录音服务器在加入第一组播组和第二组播组后接收并录制UE1发送给第一组播组地址的媒体和UE2发送给第二组播组地址的媒体。First, UE1 dials the number of UE2 to establish a call. Then, UE1 initiates a recording request during the call. After receiving the recording request sent by UE1, the call control server assigns the multicast group address maddr_1 to UE1, assigns the multicast group address maddr_2 to UE2, and then sends a SIP (Session Initiation Protocol) Reinvite message to UE1 , and carry maddr_2 in the SDP (Session Description Protocol) message body of the re-invite message as the communication address of UE2, and carry maddr_1 in the header field (such as the callinfo field) of the SIP Reinvite message to notify UE1 to join the group corresponding to maddr_1 broadcast group; send a SIP Reinvite message to UE2, carry maddr_1 in the SDP message body of the SIP Reinvite message as the communication address of UE1, and carry maddr_2 in the header field (such as the callinfo field) of the SIP Reinvite message to notify UE2 to join the multicast corresponding to maddr_2 Group. Correspondingly, after receiving the Reinvite message, UE1 will join the multicast group corresponding to maddr_1, use maddr_2 as the communication address of the communication peer to send media to maddr_2, and send a confirmation message to the call control server to inform that it has joined the multicast group corresponding to maddr_1. Multicast group; UE2 will join the multicast group corresponding to maddr_2 after receiving the Reinvite message, send media to maddr_1 using maddr_1 as the communication address of the communication peer, and send a confirmation message to the call control server to inform that it has joined the group corresponding to maddr_2 multicast group. Next, the call control server receives the confirmation messages sent by UE1 and UE2, and notifies the recording server to join the first multicast group and the second multicast group through the Web Service interface. After joining the first multicast group and the second multicast group, the recording server receives and records the media sent by UE1 to the address of the first multicast group and the media sent by UE2 to the address of the second multicast group.
在具体实施过程中，若用户想要停止录音，可以通过第一终端或第二终端向呼叫控制服务器发送用于停止录音的请求。呼叫控制服务器在接收到第一终端或第二终端发送的用于停止录音的请求时，向第二终端发送第一终端的单播地址，以便于第二终端向第一终端的单播地址发送用于与第一终端通信的媒体，向第一终端发送第二终端的单播地址，以便于第一终端向第二终端的单播地址发送用于与第二终端通信的媒体。During specific implementation, if the user wants to stop recording, he may send a request for stopping recording to the call control server through the first terminal or the second terminal. When the call control server receives the request for stopping the recording sent by the first terminal or the second terminal, it sends the unicast address of the first terminal to the second terminal, so that the second terminal sends a message to the unicast address of the first terminal. The media used for communicating with the first terminal sends the unicast address of the second terminal to the first terminal, so that the first terminal sends the media used for communicating with the second terminal to the unicast address of the second terminal.
例如，图4中P8用户1执行停止录音的操作，通过第一终端向呼叫控制服务器发送用于停止录音的请求。相应的，呼叫控制服务器在接收到用于停止录音的请求时，向第一终端发送重邀请消息以获取在停止录音后用于与第二终端继续通信的第一终端的单播地址。第一终端执行P9接收呼叫控制服务器发送的重邀请消息，向呼叫控制服务器发送用于与第二终端继续通信的单播地址1；如：第一终端自身的IP地址。接下来，呼叫控制服务器接收第一终端的单播地址1，执行P10向第二终端发送重邀请消息以获取在停止录音后用于与第一终端继续通信的第二终端的单播地址并告知第二终端通信对端的单播地址1，以使第二终端在收到重邀请消息后，向呼叫控制服务器反馈自身的单播地址2；如：第二终端自身的IP地址。随后，呼叫控制服务器接收单播地址2，并将该单播地址2发送给第一终端。此后，第一终端和第二终端分别执行P11和P12退出第一组播组和第二组播组，通过单播地址1和单播地址2继续进行点对点的单播通信。For example, in FIG. 4, P8 user 1 performs an operation of stopping recording, and sends a request for stopping recording to the call control server through the first terminal. Correspondingly, when receiving the request for stopping the recording, the call control server sends a re-invitation message to the first terminal to acquire the unicast address of the first terminal for continuing to communicate with the second terminal after the recording is stopped. The first terminal executes P9 to receive the re-invitation message sent by the call control server, and sends the unicast address 1 for continuing communication with the second terminal to the call control server; for example, the IP address of the first terminal itself. Next, the call control server receives the unicast address 1 of the first terminal, and executes P10 to send a re-invitation message to the second terminal to obtain the unicast address of the second terminal for continuing to communicate with the first terminal after the recording is stopped and informs The unicast address 1 of the communication peer of the second terminal, so that the second terminal feeds back its own unicast address 2 to the call control server after receiving the re-invitation message; for example, the second terminal's own IP address. Subsequently, the call control server receives the unicast address 2 and sends the unicast address 2 to the first terminal. Thereafter, the first terminal and the second terminal respectively execute P11 and P12 to exit the first multicast group and the second multicast group, and continue point-to-point unicast communication through unicast address 1 and unicast address 2.
相应的，呼叫控制服务器在将第二终端的单播地址2发送给第一终端后，第一终端便可以通过单播地址2与第二终端进行通信，第二终端也可以通过单播地址1与第一终端进行通信，那么呼叫控制服务器可以直接回收第一组播组地址和第二组播组地址。当然，呼叫控制服务器还可以在接收到第一终端或第二终端发送的用于停止录音的请求时，通知第一终端退出第一组播组，通知第二终端退出第二组播组，通知录音服务器停止录音并退出第一组播组和第二组播组，并在确定第一终端和录音服务器均已退出第一组播组时回收第一组播地址，在确定第二终端和录音服务器均已退出第二组播组时回收第二组播地址。可见，呼叫控制服务器通过动态分配组播组地址及回收组播组地址，以使空闲的组播组地址能够用于其它业务，由此提高组播地址的利用率。Correspondingly, after the call control server sends the unicast address 2 of the second terminal to the first terminal, the first terminal can communicate with the second terminal through the unicast address 2, and the second terminal can also communicate with the second terminal through the unicast address 1. To communicate with the first terminal, the call control server can directly recover the first multicast group address and the second multicast group address. Certainly, the call control server may also notify the first terminal to withdraw from the first multicast group, notify the second terminal to withdraw from the second multicast group, and notify The recording server stops recording and exits the first multicast group and the second multicast group, and recycles the first multicast address when it is determined that both the first terminal and the recording server have exited the first multicast group, and when the second terminal and the recording server are determined The second multicast address is reclaimed when all the servers have exited the second multicast group. It can be seen that the call control server dynamically allocates multicast group addresses and reclaims multicast group addresses so that idle multicast group addresses can be used for other services, thereby improving the utilization rate of multicast addresses.
请参考图5，当第一终端具有自动录音权限时，对应本申请实施例提供的录音系统本申请实施例还提供第二种录音方法，应用于呼叫控制服务器。第二种录音方法可以应用于第一终端开启了自动录音业务的场景中。具体的，第二种录音方法包括：Please refer to FIG. 5 , when the first terminal has automatic recording authority, corresponding to the recording system provided in the embodiment of the present application, the embodiment of the present application also provides a second recording method, which is applied to the call control server. The second recording method may be applied in a scenario where the first terminal has enabled the automatic recording service. Specifically, the second recording method includes:
S501：所述呼叫控制服务器接收所述第一终端发送的请求与第二终端进行通信的呼叫请求，所述呼叫请求中包含所述第一终端所在的第一组播组的第一组播组地址；S501: The call control server receives a call request sent by the first terminal requesting to communicate with the second terminal, and the call request includes the first multicast group of the first multicast group where the first terminal is located address;
S502：所述呼叫控制服务器在确定所述第一终端已开启自动录音业务时，为所述第二终端分配第二组播组地址，将所述第二组播组地址加入所述呼叫请求并向所述第二终端发送修改后的呼叫请求，以使得所述第二终端加入所述第二组播组地址对应的第二组播组并向所述第一组播组地址发送用于与所述第一终端通信的媒体；S502: When determining that the first terminal has enabled the automatic recording service, the call control server allocates a second multicast group address to the second terminal, adds the second multicast group address to the call request, and sending a modified call request to the second terminal, so that the second terminal joins the second multicast group corresponding to the second multicast group address and sends a call request to the first multicast group address for communicating with the first multicast group address the medium of communication of the first terminal;
S503：所述呼叫控制服务器将接收的所述第二终端发送的包括所述第二组播组地址的呼叫响应转发给所述第一终端，以便于所述第一终端向所述第二组播组地址发送用于与所述第二终端通信的媒体；S503: The call control server forwards the received call response including the second multicast group address sent by the second terminal to the first terminal, so that the first terminal sends a call response to the second group sending the media used for communicating with the second terminal through the broadcast group address;
S504：所述呼叫控制服务器将所述第一组播组地址和所述第二组播组地址发送给录音服务器，以使所述录音服务器加入所述第一组播组和所述第二组播组以接收并录制所述第一终端和所述第二终端发送的媒体。S504: The call control server sends the first multicast group address and the second multicast group address to the recording server, so that the recording server joins the first multicast group and the second group broadcast group to receive and record the media sent by the first terminal and the second terminal.
请参考图6，由于第一终端开启了自动录音业务，所以呼叫控制服务器在接收第一终端发送的开启自动录音业务的消息时，标记第一终端已开启自动录音业务如：“record=on”，并为第一终端分配第一组播组地址maddr_1，并通知第一终端加入第一组播组。例如：呼叫控制服务器可以通过执行P2：通过向第一终端发送信令消息（如携带maddr_1的SIPinfo消息）通知第一终端加入第一组播组。第一终端在加入第一组播组后，同样将发送确认消息告知呼叫控制服务器其已加入第一组播组。那么，第一终端在需要与第二终端建立通信连接时，执行P3向呼叫控制服务器发送呼叫请求，请求与第二终端建立通信连接，其中该呼叫请求中包含第一终端所在第一组播组对应的第一组播组地址maddr_1。Please refer to Figure 6. Since the first terminal has enabled the automatic recording service, the call control server will mark that the first terminal has enabled the automatic recording service when receiving the message of enabling the automatic recording service sent by the first terminal, such as: "record=on" , and allocate the first multicast group address maddr_1 to the first terminal, and notify the first terminal to join the first multicast group. For example, the call control server may execute P2: notify the first terminal to join the first multicast group by sending a signaling message (such as a SIPinfo message carrying maddr_1) to the first terminal. After the first terminal joins the first multicast group, it also sends a confirmation message to inform the call control server that it has joined the first multicast group. Then, when the first terminal needs to establish a communication connection with the second terminal, it executes P3 to send a call request to the call control server, requesting to establish a communication connection with the second terminal, wherein the call request includes the first multicast group where the first terminal belongs The corresponding first multicast group address maddr_1.
为此，呼叫控制服务器执行S501接收第一终端发送的请求与第二终端进行通信的呼叫请求。在确定所述第一终端已开启自动录音业务时，接着执行S502即P4：为所述第二终端分配第二组播组地址，将所述第二组播组地址加入所述呼叫请求并向所述第二终端发送修改后的呼叫请求，以使得所述第二终端加入所述第二组播组地址对应的第二组播组并向所述第一组播组地址发送用于与所述第一终端通信的媒体。To this end, the call control server executes S501 to receive a call request sent by the first terminal to communicate with the second terminal. When it is determined that the first terminal has started the automatic recording service, then perform S502 or P4: assign a second multicast group address to the second terminal, add the second multicast group address to the call request and send The second terminal sends the modified call request, so that the second terminal joins the second multicast group corresponding to the second multicast group address and sends a call request to the first multicast group address for communicating with the second multicast group address. The medium for communicating with the first terminal.
在S502之后，第二终端接收呼叫控制服务器发送的修改后的呼叫请求，从呼叫请求中获取第二组播组地址，并加入第二组播组。然后，第二终端向呼叫控制服务器发送响应呼叫请求的呼叫响应，该呼叫响应包括第二组播组地址用于通过呼叫控制服务器通知第一终端通信对端对应的第二组播组地址。紧接着，呼叫控制服务器执行S503将接收的第二终端发送的包括所述第二组播组地址的呼叫响应转发给所述第一终端，以便于所述第一终端向所述第二组播组地址发送用于与所述第二终端通信的媒体。相应的，第一终端执行P6接收呼叫响应获得作为通信对端的第二组播组地址，并通过呼叫控制服务器与第二终端确认通信。After S502, the second terminal receives the modified call request sent by the call control server, obtains the address of the second multicast group from the call request, and joins the second multicast group. Then, the second terminal sends a call response in response to the call request to the call control server, where the call response includes the second multicast group address and is used to notify the first terminal of the corresponding second multicast group address to the communication peer through the call control server. Next, the call control server executes S503, and forwards the received call response including the second multicast group address sent by the second terminal to the first terminal, so that the first terminal can broadcast to the second multicast The group address sends media used to communicate with said second terminal. Correspondingly, the first terminal executes P6 to receive the call response to obtain the second multicast group address as the communication peer, and confirms the communication with the second terminal through the call control server.
进一步的，呼叫控制服务器接着执行S504将所述第一组播组地址和所述第二组播组地址发送给录音服务器，以使所述录音服务器加入所述第一组播组和所述第二组播组以接收并录制所述第一终端和所述第二终端发送的媒体。具体的，呼叫控制服务器可以在接收到第一终端发送的确认与第二终端通信的响应消息之后，将第一组播组地址和第二组播组地址发送给录音服务器，也可以在接收到第二终端发送的呼叫响应，向第一终端转发呼叫响应的同时将第一组播组地址和第二组播组地址发送给录音服务器，加速录音进程。Further, the call control server then performs S504 to send the first multicast group address and the second multicast group address to the recording server, so that the recording server joins the first multicast group and the second multicast group The second multicast group is used to receive and record the media sent by the first terminal and the second terminal. Specifically, the call control server may send the first multicast group address and the second multicast group address to the recording server after receiving the response message sent by the first terminal to confirm communication with the second terminal, or may send the first multicast group address to the recording server after receiving The call response sent by the second terminal forwards the call response to the first terminal and at the same time sends the first multicast group address and the second multicast group address to the recording server, thereby speeding up the recording process.
由于第一终端与第二终端的通信为组播通信，第一终端发送媒体流时执行P9：通过路由器将媒体复制转发给第二组播组的组员：第二终端和录音服务器。同样的，第二终端发送媒体时执行P10：通过路由器将媒体复制转发给第一组播组的组员：第一终端和录音服务器。因此录音服务器能够接收并录制第一终端和第二终端发送的媒体，从而对第一终端和第二终端的通话进行录音。可见，通过组播录音不需要在MCU上创建会场节约了媒体资源，不需要对媒体流进行混音，减少了会场混音造成的延时，提升了录音场景下的语音质量。Since the communication between the first terminal and the second terminal is multicast communication, when the first terminal sends the media stream, execute P9: copy and forward the media to the members of the second multicast group through the router: the second terminal and the recording server. Similarly, when the second terminal sends media, execute P10: copy and forward the media to the members of the first multicast group through the router: the first terminal and the recording server. Therefore, the recording server can receive and record the media sent by the first terminal and the second terminal, so as to record the conversation between the first terminal and the second terminal. It can be seen that the multicast recording does not need to create a site on the MCU, which saves media resources, does not need to mix media streams, reduces the delay caused by site mixing, and improves the voice quality in the recording scene.
例如，假设UE1开启了自动录音业务；UE1和UE2均为注册在呼叫控制服务器下的用户；呼叫控制服务器与录音服务器通过Web Service接口对接。UE1与UE2的录音过程如下：For example, assume that UE1 has enabled the automatic recording service; both UE1 and UE2 are users registered under the call control server; the call control server and the recording server are interconnected through the Web Service interface. The recording process of UE1 and UE2 is as follows:
首先，第一终端UE1拨打第二终端UE2的号码向呼叫控制服务器发送呼叫请求（SIPinvite消息），在SIP invite消息中的SDP消息体中携带自身所在第一组播组对应的第一组播组地址（maddr_1）。然后，呼叫控制服务器在收到UE1发送的呼叫请求后，为第二终端分配第二组播组地址（maddr_2），并将maddr_2添加到SIP invite消息中获得修改后的呼叫请求并发送给UE2。于是，UE2根据接收到的SIP invite消息获取呼叫方UE1的通信地址（maddr_1）；UE2根据接收到的修改后的呼叫请求中要求第二终端加入的第二组播组对应的第二组播组地址maddr_2，第二终端加入第二组播组，并通知呼叫控制服务器其已加入第二组播组（maddr_2），并通过呼叫控制服务器向UE1返回呼叫响应（如临时响应消息、200OK响应消息等），并在呼叫响应的SDP消息体中携带maddr_2作为自身的通信地址。第一终端通过呼叫控制服务器向第二终端确认收到第二终端的通信地址确认建立通信连接，于是UE1发送媒体到第二组播组，UE2发送媒体到第一组播组，实现UE1与UE2的通信。接下来，呼叫控制服务器可以通过Web Service接口通知录音服务器加入第一组播组(maddr_1)和第二组播组(maddr_2)。录音服务器在加入第一组播组和第二组播组便可以对第一组播组和第二组播组收到的媒体进行录制。First, the first terminal UE1 dials the number of the second terminal UE2 to send a call request (SIPinvite message) to the call control server, and the SDP message body in the SIP invite message carries the first multicast group corresponding to the first multicast group it belongs to Address (maddr_1). Then, after receiving the call request sent by UE1, the call control server assigns the second multicast group address (maddr_2) to the second terminal, adds maddr_2 to the SIP invite message to obtain a modified call request, and sends it to UE2. Therefore, UE2 obtains the communication address (maddr_1) of the calling party UE1 according to the received SIP invite message; address maddr_2, the second terminal joins the second multicast group, and notifies the call control server that it has joined the second multicast group (maddr_2), and returns a call response (such as a temporary response message, 200OK response message, etc.) to UE1 through the call control server ), and carries maddr_2 as its own communication address in the SDP message body of the call response. The first terminal confirms to the second terminal through the call control server that it has received the communication address of the second terminal to confirm the establishment of a communication connection, so UE1 sends media to the second multicast group, and UE2 sends media to the first multicast group, realizing UE1 and UE2 Communication. Next, the call control server may notify the recording server to join the first multicast group (maddr_1) and the second multicast group (maddr_2) through the Web Service interface. After the recording server joins the first multicast group and the second multicast group, it can record the media received by the first multicast group and the second multicast group.
在具体实施过程中，呼叫控制服务器将第一组播组地址和第二组播组地址发送给录音服务器之后，若呼叫控制服务器检测到第一终端挂机，则向第二终端发送用于提示第二终端退出组播组的提示消息；然后，呼叫控制服务器接收提示消息对应的反馈消息，回收所述第二组播组地址，其中，反馈消息用于表明第二终端已退出第二组播组。当然，呼叫控制服务器也可以检测到第一终端挂机之后，直接执行P12回收第二组播组地址。可见，在第一终端开启自动录音业务时，呼叫控制服务器预先给第一终端分配第一组播地址，并在通话结束后使第一终端保留第一组播地址，减少第一终端在进行通话录音时信令协商步骤。In the specific implementation process, after the call control server sends the first multicast group address and the second multicast group address to the recording server, if the call control server detects that the first terminal hangs up, it will send a message to the second terminal to prompt the second The prompt message for the second terminal to withdraw from the multicast group; then, the call control server receives the feedback message corresponding to the prompt message, and reclaims the address of the second multicast group, wherein the feedback message is used to indicate that the second terminal has withdrawn from the second multicast group . Of course, the call control server may also directly execute P12 to recover the second multicast group address after detecting that the first terminal hangs up. It can be seen that when the first terminal starts the automatic recording service, the call control server pre-allocates the first multicast address to the first terminal, and makes the first terminal retain the first multicast address after the call is over, reducing the number of calls made by the first terminal. Signaling negotiation steps during recording.
当然，在第一终端关闭自动录音业务时，呼叫控制服务器则相应的回收第一组播组地址。具体的，在检测到第一终端挂机之后，用户可以通过第一终端关闭自动录音业务，为此在检测到第一终端挂机之后，呼叫控制服务器还接收第一终端发送的用于关闭自动录音业务的请求消息，回收第一组播组地址。Of course, when the automatic recording service is disabled by the first terminal, the call control server correspondingly recovers the first multicast group address. Specifically, after detecting that the first terminal is on-hook, the user can turn off the automatic recording service through the first terminal. For this reason, after detecting that the first terminal is on-hook, the call control server also receives a message for turning off the automatic recording service sent by the first terminal. request message to recycle the first multicast group address.
