Abstract

The invention discloses a communication method, equipment and system, belonging to the field of communication. The method includes: the source terminal device sends a speakerphone call instruction to the transmission device, the speakerphone call instruction includes the time slot allocated by the source terminal device for the speakerphone service, the identifier of the destination terminal device, and the speakerphone service type identifier, The speakerphone service is used for voice transmission when the destination terminal device is not off-hook; the source terminal device receives the speakerphone connection instruction sent by the transmission device, and the speakerphone connection instruction includes the The speaker service type identifier; the source terminal device sends a one-way voice signal to the transmission device through the time slot allocated by the source terminal device for the speaker service, so that the transmission device transmits the one-way voice signal sent to the destination terminal device. The present invention realizes the called user to answer without picking up the phone through the above method, and improves the use efficiency of the communication equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, device and system. Background technique [0002] At present, the command telephone system equipped on large ships can realize two types of business: internal communication and external communication. Among them, intercom services include point-to-point services, pre-programmed conference (half-duplex, full-duplex) services, programmable conference (half-duplex, full-duplex) services, voice telephone services, broadcasting, alarm services, telephone (automatic Telephone, ship mobile phone, digital trunk telephone, analog trunk telephone) business, etc. [0003] During the call process of the point-to-point service, when the user initiates a call through the terminal device, the called user needs to manually pick up the phone to connect to the point-to-point service and conduct a voice conversation, resulting in low work efficiency in actual use.
