Problems solved by technology
[0003] Due to the broadcast feature of the half-duplex voice group call technology, the private network communication system cannot accurately obtain the working status of the terminal. Therefore, during the communication process, when the system wants to send instructions or data to the terminal, it can only use polling. Data can only be sent to the terminal after the terminal is pulled, so the system cannot maintain uninterrupted communication with the terminal, nor can it achieve uninterrupted flexible data service communication

The embodiment of the invention discloses a half-duplex communication method, a terminal and a transmitting station, and aims to keep continuous data communication in a half-duplex special-net communication system. The half-duplex communication method provided in the embodiment of the invention comprises the following steps that: a terminal receives a channel distribution instruction sent by the transmitting station; the channel distribution instruction is used for indicating a half-duplex voice channel and a data channel distributed to the terminal; the terminal performs half-duplex voice communication through the half-duplex voice channel and sends first application data and an identifier of the terminal to the transmitting station through the data channel; the identifier of the terminal is used for enabling the transmitting station to associate the data channel with the terminal; and the terminal receives second application data sent by the system through the data channel. The terminal sends the self identifier to the transmitting station; the transmitting station associates the data channel with the terminal; therefore, data can be subsequently sent to the terminal through the data channel; and thus, continuous data communication in the half-duplex special-net communication system can be kept.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a half-duplex communication method, a terminal and a transmitting station. Background technique [0002] In the current main private network communication system standards and products, half-duplex communication is adopted to realize the voice group call service. During the voice call, the system can only send a small amount of information to the speaking party through reverse signaling. [0003] Due to the broadcast feature of the half-duplex voice group call technology, the private network communication system cannot accurately obtain the working status of the terminal. Therefore, during the communication process, when the system wants to send instructions or data to the terminal, it can only use polling. Data can only be sent to the terminal after the terminal is pulled, so the system cannot maintain uninterrupted communication with the terminal, nor can it realize uninte...
