Abstract

The present invention provides a wide-narrowband fusion system, a terminal and a voice communication method. The chip processor core determines whether the service encoded and processed is a broadband service, a narrowband service or a wide-narrowband service, and if it is a narrowband service or a narrowband radio frequency modulation data of the wide-narrowband service , the first digital processing core outputs the audio data and the narrowband radio frequency modulation data to the programmable device controller, and the programmable device controller outputs the processed narrowband radio frequency modulation data to the peripheral circuit. If it is broadband radio frequency modulation data of a broadband service or wide-narrowband service, output the broadband radio frequency modulation data to the second digital signal processing core, and the second digital signal processing core outputs the processed broadband radio frequency modulation data to the peripheral circuit. Therefore, the walkie-talkie can flexibly switch various transmission modes and coexist with multiple modes, and meet the trend of private network development.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a wide-narrowband fusion system, a terminal and a voice communication method. Background technique [0002] At present, with the rapid development of the mobile communication industry, the demand for walkie-talkies continues to increase worldwide. As a ubiquitous two-way mobile communication tool, users have higher and higher performance requirements for walkie-talkies. [0003] In the prior art, the traditional walkie-talkie uses a small real-time operating system to modulate the stored signal on the walkie-talkie's transmission frequency, and the main functions are voice intercom and low-speed data communication. At present, for the walkie-talkie in the private network, the voice intercom and data communication can only be performed in the same broadband public network or private network, or within the narrowband private network, and cannot be switched between each...
