AI Technical Summary

Technical Problem

In private network communication, when the repeater fails to work properly, the communication terminal cannot receive the valid downlink frames from the repeater, resulting in communication failure. In the existing technology, when switching to direct mode, it is impossible to determine whether the called terminal can receive the direct call, which may lead to a waste of channel resources.

Method used

When a relay call fails, the calling terminal switches to direct mode and sends a call request containing call mode information. After receiving confirmation from the called terminal, communication is established to ensure that the called terminal can receive the direct call. If the relay station is unavailable, direct communication is re-established.

Benefits of technology

It achieves seamless handover, improves user experience, avoids waste of channel resources, ensures that the called terminal can receive direct calls, and improves communication success rate.

Abstract

Embodiments of the present application disclose a communication method, device, equipment and storage medium. The method comprises: when a transit call connection switching to a first transit mode fails, switching to a first direct mode and sending a call request to the outside, the call request containing call mode information of a calling terminal; and after receiving confirmation information returned by a called terminal, the calling terminal and the called terminal establish communication, wherein the confirmation information is generated by the called terminal after switching to the direct mode according to the call request. Embodiments of the present application can reestablish direct communication when a transit station is unavailable, on the premise that the called terminal can receive direct calls, without manual switching by the user, with smooth switching, no-sense switching, improved user experience, and direct communication on the premise that the called terminal can receive, avoiding waste of channel resources caused by occupying channel resources when there is no actual communication service.
