Hytera Communications has filed a patent for a voice communication method and system that addresses the issue of voice size inconsistency between broadband and narrow-band terminals. The method involves reducing the energy amplitude of voice data when a broadband terminal calls a narrow-band terminal, and amplifying the energy amplitude when a narrow-band terminal calls a broadband terminal. This aims to enhance the user experience in a broadband and narrow-band intercommunication environment.

A recently filed patent (Publication Number: US20230118085A1) describes a voice communication method for a broadband and narrowband intercommunication environment. The method involves reducing the energy amplitude of voice data when a broadband terminal calls a narrowband terminal, and amplifying the energy amplitude when the narrowband terminal calls the broadband terminal. This allows for effective communication between broadband and narrowband terminals.

In the case of a group call, the method involves collecting voice data to generate a normal voice data packet, which is then sent to other broadband terminals in the group call. This ensures that all participants in the group call receive the necessary voice data.

The method further explains the process of executing the reducing operation on the energy amplitude of the voice data. This includes collecting the voice data, performing a reducing process on the energy amplitude, and sending the reduced voice data to a coder. The coder adds a type field in the packet header and generates the reduced voice data packet based on the packet header and the voice data.

The patent also describes a voice communication system that includes a broadband terminal, a broadband system, a narrowband terminal, a narrowband system, and an Internet Protocol (IP) Multimedia Subsystem (IMS). The system allows for seamless communication between broadband and narrowband terminals by executing the reducing and amplifying operations on the voice data packets.

In summary, the patent presents a voice communication method and system for a broadband and narrowband intercommunication environment. The method involves reducing and amplifying the energy amplitude of voice data packets to ensure effective communication between broadband and narrowband terminals. The system includes various components to facilitate this communication process.
