Full-Duplex Group Call Channel Control

The patent segments the communication group into multiple communication channels, each capable of full-duplex transmission. Instead of allowing all users to transmit simultaneously on a single channel (which would cause overload), the system divides the group into smaller sub-groups with separate channels, enabling parallel full-duplex communication while controlling load on each individual channel.

The patent implements dynamic channel allocation where communication channels are dynamically assigned and reconfigured based on current transmission needs. The system can adjust the number and configuration of full-duplex channels in real-time, allowing optimal utilization of network resources while preventing overload by adapting to changing communication demands.

The patent introduces a channel management function as an intermediary layer between the user terminals and the core server. This intermediary handles the establishment, modification, and release of communication channels locally at the terminal level, reducing the need for continuous server intervention. The server only performs high-level control while local terminals manage real-time channel operations, thereby minimizing delays.

The patent implements preliminary channel establishment where communication channels are pre-configured and ready before actual transmission begins. The system proactively manages channel lifecycles including pre-establishment, active transmission, and post-transmission release, ensuring that channels are immediately available when needed without waiting for server approval during critical transmission moments.
