the OTT platform system further comprises a signaling gateway, wherein the signaling gateway is used for receiving a serial number sent by terminal equipment before acquiring identification information of the terminal equipment from the call request when receiving the call request of the terminal equipment, generating virtual number information according to the serial number, sending the virtual number information to the terminal equipment as the identification information of the terminal equipment, sending an account opening request to the terminal equipment when receiving a first registration request of the terminal equipment, analyzing the second registration request to obtain verification information when receiving a second registration request sent by the terminal equipment and account opening information corresponding to the account opening request, judging whether the account opening information is consistent with the verification information, and if not, sending an account opening request to the terminal equipment without passing the request; if the two types of the terminal equipment are consistent, sending an account opening passing request to the terminal equipment;
the establishing an audio-video call channel between the terminal device and the communication device according to the communication setup message includes:
converting the communication construction message into a construction protocol conforming to a multimedia communication protocol;
and sending the set-up protocol to the terminal equipment to finish the establishment of the audio and video call channel between the terminal equipment and the communication equipment.
