[0029] Broadcast terminal 140; wherein,

[0030] The client 110 sends an audio broadcast request to each sub-node router 142 based on different network types. Each sub-node router 142 forwards the audio broadcast request and each sub-node network identifier to the AI ​​middle station 122. The AI ​​middle station 122 sends the audio broadcast task to each sub-node 141 based on the network identifier for audio broadcast.

[0031] Among them, different network types include public networks and private networks.

[0032] In other words, the client can flexibly send audio broadcast requests based on different network types, and each sub-node route receives and forwards these requests, ensuring timely processing of the requests.

The audio transmission system according to claim 6, characterized in that: When the convergence gateway obtains the voice gateway and the broadcast terminal access gateway, the voice gateway and the broadcast terminal access gateway are sent to the broadcast terminal, so that the broadcast terminal performs audio broadcast based on the voice gateway and the broadcast terminal access gateway, including: The convergence gateway obtains the voice gateway domain name corresponding to each sub-node network based on the network identifier of each sub-node, and forwards the identifier of the broadcast terminal and the audio download address to the corresponding voice gateway based on the voice gateway domain name; The voice gateway sends the broadcast terminal access gateway to the convergence gateway, and the voice gateway obtains the audio file from the resource pool and sends the audio file to the broadcast terminal access gateway; The convergence gateway forwards the broadcast terminal access gateway to the broadcast terminal, and the broadcast terminal broadcasts based on the audio file when a long connection is established based on the broadcast terminal access gateway.

8. An audio transmission method, characterized in that: include: The client sends audio broadcast requests to each sub-node route based on different network types; Each sub-node routing forwards the audio broadcast request and each sub-node network identifier to the AI ​​middle station; The AI ​​middle station sends the audio broadcast task to each sub-node based on the network identifier for audio broadcast.

9. An electronic device, characterized in that: include: at least one processor; as well as a memory communicatively connected to the at least one processor; wherein, The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform the method of claim 8.

10. A non-transitory computer-readable storage medium storing computer instructions, characterized in that: The computer instructions are used to cause the computer to execute the method of claim 8.
