In recent years, with the continuous development of network technologies, especially from a narrowband technology to a 4G LTE broadband technology, people no longer meet the narrowband requirements of ordinary voice talkback and short data transmission, and instead pursue video talkback, picture transmission and the like with higher bandwidth requirements.

Due to the narrow-band bandwidth limitation, the network access speed of the digital interphone adopting the DMR, PDT and other systems is usually 56Kbps or below, so that the digital interphone is mainly used for transmitting low-code-stream voice and small data packet communication. Therefore, the narrow-band technology adopting the systems such as DMR and PDT mainly solves the problem of real-time transmission of voice and signaling during operation of wireless communication equipment, and cannot transmit large data services such as video and images, which is one of the limitations and regulations in the application of the existing narrow-band technology.

Therefore, broadband terminal equipment and narrow terminal equipment based on broadband technology are different in voice structure, communication protocol and frequency and are isolated in the voice communication process, like information islands, the broadband terminal equipment and the narrow terminal equipment are also independent and dispersed with each other, a network coverage form in the true sense is not achieved, and service data cannot be smoothly interconnected and uniformly dispatched and directed.

the scheduling command module performs scheduling according to the category to which the message belongs, and comprises the following steps:
when the acquired message is a voice signaling which is sent by a broadband terminal and carries a unique ID code of a target narrowband terminal, after verification, a call is initiated to the target narrowband terminal;
when the acquired message is a voice packet which is sent by a broadband terminal and carries the unique ID code of the target narrowband terminal, the voice packet is sent to the target narrowband terminal through a special digital interface after being subjected to audio decoding to carry out channel transmission;
when the acquired message is voice sent by the narrow-band terminal, the voice is sent to the server after being encoded into a broadband encoding format by audio, the whole mapping relation table is traversed, and whether the voice carries the unique ID code of the cross-region narrow-band terminal is judged; otherwise, the voice in the broadband coding format is forwarded to the broadband terminal, if so, the voice in the broadband coding format is sent to a network interface corresponding to the cross-region narrowband terminal mapped by the unique ID code, and the voice is sent to a target narrowband terminal through a special digital interface after audio decoding for channel transmission.
7. The system of claim 6, wherein: the dual-network convergence communication module comprises a registration module, wherein the registration module comprises an AIS protocol of DMR/PDT narrow-band relay for registering the narrow-band terminal to the server, and further comprises a standard SIP protocol for registering the broadband terminal to the server.
8. The wide-narrow converged scheduling communication system of claim 7, wherein: the system comprises a broadband terminal, a narrowband terminal and a server, wherein the broadband terminal is computer equipment connected with the server, the narrowband terminal is an interphone with a DMR/PDT system, and the interphone of the narrowband terminal is added with an talkback component communicated with the computer equipment of the broadband terminal and other interphones and short messages on a narrowband terminal cluster.
9. A wide-narrow converged scheduling communication device comprising a memory and a processor, the memory storing a computer program, characterized in that the processor, when executing the computer program, implements the steps of the method of any one of claims 1 to 5.
