It should be noted that, after the first media channel is established, the user inputs the conference account information through the terminal device, and then the terminal device sends the conference account information to the IVR service node through the first media channel.
The conference account information comprises: conference group number; the conference account information may also include a password.
After the terminal device sends the conference account information to the IVR service node, the IVR service node executes S24.
S24: the IVR service node receives conference account information sent by the terminal equipment through the first media channel through a port corresponding to the first port number; the conference account information includes: conference group number.
The conference account information may also include a password.
It should be noted that, because the terminal device is conference account information sent to the IVR service node through the first media channel, the IVR service node may receive the conference account information through a port corresponding to the first port number (i.e., a port of the IVR service node).
After the IVR service node receives the conference account information sent by the terminal device, the IVR service node executes S25.
S25: and the IVR service node sends the conference account information to the call control node.

A2: and when the management control node determines that the conference account information is correct, the management control node sends the conference group number to the call control node.
When the IVR service node only sends the conference account information to the management control node, the A2 may be implemented in a manner that the management control node determines whether the conference account information is pre-stored conference account information, if yes, determines that the conference account information is correct, and then sends the conference group number in the conference account information to the call control node.
It should be noted that, when the management control node determines that the conference account information is wrong, the management control node does not send the conference group number in the conference account information to the call control node.
As one embodiment, A2 includes: and when the management control node determines that the conference account information is correct, the management control node sends the conference group number and the number of the terminal equipment to the call control node.

Upon determining that there is no conference corresponding to the conference group number, the management control node executes step a22.
A22: the management control node sends a conference creation request to the target conference service node; the creation request includes: the conference group number.
In an actual implementation, a22 may be implemented in such a manner that the management control node generates a conference creation request based on the conference group number, and transmits the conference creation request to the target conference service node based on the IP address of the target conference service node determined in advance.
A23: the target conference service node creates a conference corresponding to the conference group number based on the conference group number.
In the actual implementation process, a23 may be implemented in a manner that after receiving the conference creation request, the target conference service node extracts a conference group number from the conference creation request, and creates a conference corresponding to the conference group number in the target conference service node, where the conference group number may be regarded as a unique identifier of the conference, and conference group numbers corresponding to the conferences are different.
A24: the management control node sends the conference group number to the call control node.
In actual implementation, a24 may be implemented in such a way that the management control node sends the conference group number to the call control node based on a predetermined IP address of the call control node.

It can be understood that the conference corresponding to the conference group number sent by the terminal device is already created by the target conference service node, and then the third IP address of the target conference service node corresponding to the conference group number can be found out in the corresponding relationship.
After the management control node locates the third IP address of the target conference service node, the management control node performs step a28.
A28: and the management control node sends the third IP address and the conference group number to the call control node.
In actual implementation, a28 may be implemented as follows, where the management control node sends the third IP address of the target conference service node and the conference group number to the call control node based on the IP address of the call control node.
As an embodiment, a28 may also be implemented in such a way that the management control node sends the third IP address, the conference group number and the number of the terminal device to the call control node.
After the call control node receives the conference group number, the call control node performs S26.
S26: the call control node sends a third establishment request to the target conference service node to establish a third session channel; the third setup request includes: the third setup request includes: the conference group number, and a second IP address and a second port number of the terminal device corresponding to the number of the terminal device; the third session path is a session path between the target conference service node and the call control node.

If the management control node sends the third IP address of the target conference service node to the call control node together with the conference group number, S26 may be implemented as follows, as an implementation manner, where the call control node sends the first IP address, the first port number, and the conference group number to the target conference service node corresponding to the third IP address based on the third IP address of the target conference service node.
If the management control node sends the number of the terminal device and the conference group number to the call control node, as another embodiment, S26 may be implemented in such a manner that the call control node searches for a second IP address and a second port number of the terminal device corresponding to the number of the terminal device from the correspondence relationship of the number and the IP address of the device and the port number stored in advance based on the number of the terminal device sent by the management control node, generates a third establishment request based on the second IP address, the second port number, and the conference group number sent by the management control node, and sends the third establishment request to the target conference service node corresponding to the third IP address.
After the call control node sends the second IP address, the second port number, and the conference group number to the target conference service node, the target conference service node performs S27.
S27: and the target conference service node sends a third port number and a third IP address of the target conference service node to the terminal equipment through the third session channel and the first session channel so as to establish a second media channel, and the terminal equipment is accessed into a conference corresponding to the conference group number.
In the actual implementation process, S27 may be implemented in a manner that after receiving the third establishment request sent by the call control node, the target conference service node extracts the conference group number, the second IP address of the terminal device, and the second port number of the terminal device from the third establishment request, then searches for a conference corresponding to the conference group number from the conference created by itself based on the conference group number, accesses the terminal device to the conference corresponding to the conference group number based on the second IP address of the terminal device and the second port number of the terminal device, and sends the third port number and the third IP address of the target conference service node to the call control node through the third session channel, and the call control node sends the third port number and the third IP address to the terminal device through the first session channel according to the association relationship between the third session channel and the first session channel, so as to establish the second media channel between the target conference service node and the terminal device.
Wherein the third port number is the port number of an idle communication port in the target conference service node.
The conference control system also comprises other conference service nodes; as an embodiment, before step A2, the method further comprises: the management control node determines that the target conference service node is less loaded than the other conference service nodes.
Specifically, the management control node determines the number of ongoing conferences in each conference service node at the current moment according to conference records of conferences created in other conference service nodes and the target conference service node, and it can be understood that the fewer the number of conferences in the conference service node is, the smaller the load of the conference service node is, and then determines that the target conference service node is smaller than the load of other conference service nodes when the number of conferences in the target conference service node is determined to be smaller than the number of conferences in other conference service nodes.
Wherein, the meeting record includes: conference group number, and IP address of conference service node where conference corresponding to conference group number is located.
If the management control node determines that the load of the target conference service node is smaller than that of other conference service nodes, the management control node sends the conference group number to the call control node, which comprises the following steps: and the management control node sends the third IP address of the target conference service node and the conference group number to the call control node.
As an embodiment, before S24, the method further includes: and the IVR service node sends account input prompt information to the terminal equipment through the first media channel.
As an embodiment, after S24, the method further includes: the IVR service node releases the first media channel.
As an embodiment, after S24, the method further includes: the IVR service node releases the second session channel.
As an embodiment, the method further comprises: when the management control node determines that the account information of the conference is wrong, the management control node sends a first prompt instruction of the account information of the terminal equipment to the IVR service node, the IVR service node responds to the first prompt instruction, sends the account error prompt information to the terminal equipment and releases a first media channel, and sends a second prompt instruction of the account information of the terminal equipment to the call control node, and the call control node responds to the second prompt instruction and releases the first session channel;
after sending a second prompt instruction to the call control node, the IVR service node releases the second session channel.
