Broadband and narrowband fusion system, terminal and voice communication method

Abstract

The invention provides a broadband and narrowband fusion system, a terminal and a voice communication method. A chip processor core determines whether a service subjected to service coding processingis a broadband service, a narrowband service or a broadband and narrowband service; a first digital processing core outputs the audio data and the narrowband radio frequency modulation data to a programmable device controller if the service is the narrowband radio frequency modulation data of the narrowband service or the wideband and narrowband service, and the programmable device controller outputs the processed narrowband radio frequency modulation data to a peripheral circuit; if the service is broadband radio frequency modulation data of broadband service or broadband and narrowband service, the broadband radio frequency modulation data is output to a 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, an interphone can flexibly switch various transmission modes and coexist in various modes, and the development trend of a private network is met.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a broadband and narrowband fusion system, terminal and voice communication method. Background technique [0002] At present, with the rapid development of the mobile communication industry, the demand for walkie-talkies is increasing 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 to the transmission frequency of the walkie-talkie. The main functions are voice intercom and low-speed data communication. At present, for the walkie-talkie in the private network, voice intercom and data communication can only be performed in the same broadband public network or private network, or narrowband private network, and cannot be switched between each other. The deve...
