AI Technical Summary

Technical Problem

In a dual-slot communication system, when voice services occupy one time slot, other services cannot be carried out at the same time, resulting in the inability to implement specified data transmission functions, such as GPS reporting, call interruption and heartbeat detection, etc., which cannot be completed.

Method used

By reserved channels during voice service transmission, voice coded data is transmitted using the stealing bit position, the free position after voice compression and the embedded position, and the transmission is reduced or stopped at the reserved channel position to ensure the normal transmission of voice service, and at the same time, channels are reserved for other devices for specified data transmission.

Benefits of technology

It realizes the reservation of channels for other devices during the voice service process, ensures the normal transmission of voice service, and successfully completes the transmission of specified data, meeting the needs of functions such as center jump detection, GPS reporting and voice priority interruption of railway leveling system.

Abstract

The invention discloses a service sending method, a service receiving method, a specified data sending method and a related device, and relates to the field of communication, and the method comprises the steps that a digital intercom device responds to a voice service sending demand, transmits voice service data at a first position, and reduces the power for transmission or stops transmission at a second position, and finally, the voice service sending task containing the reserved channel is realized. According to the invention, the voice coding data is transmitted by occupying at least one of the bit stealing position outside the reserved channel, the spare position after voice compression and the embedded position, that is, the voice coding data bearing capacity of the first position is increased by compressing the voice coding data or utilizing the additional embedded position, and normal transmission of voice service is ensured; according to the method and the device, power transmission is reduced or transmission is stopped at the second position, so that channel reservation in the voice process is realized, a basis is provided for other equipment to transmit and receive specified data by using the reserved channel in the service process, and function realization depending on the specified data is ensured.
