Device and method for improving survivability of wireless voice calling based on packet

摘要

A device and method for improving the survivability of a packet-based wireless voice call according to a preferred embodiment of the present invention does not require an additional pre-packet exchange for starting a voice session, and uses a voice session maintenance function using count information of voice packets. By enabling survivable voice calls in poor conditions, voice calls can be made by quickly configuring the network without prior preparation in unplanned situations, and joining the network without specifying the network size and maintaining network synchronization is not heavy. It can quickly adapt to changes in network size such as withdrawal and movement, and based on robust voice call technology, it can improve the survivability of voice calls in poor channel environments such as mountainous areas and accident sites.
