Problems solved by technology

The color code, source address, and destination address in BCDEF are the same as A. If an error occurs at any position in the color code, source address, or destination address, and it exceeds the error correction range, the head slot should be the same as in BCEDF. information becomes different, making it impossible for the receiver to deterministically establish a voice call link

Embodiment Construction

[0039] Such as image 3 As shown, the embodiment of the present invention provides a voice transmission method, which can be specifically implemented through the following steps:

[0040] Step 301, when sending a voice superframe, the sending end places a synchronization code and complete signaling parameters in the header time slot of each voice superframe, which includes all parameters used to establish a voice call link parameter;

[0041] In the implementation of the present invention, the structure of the voice superframe is as Figure 4 As shown, among them, the 0 time slot of the voice superframe is the first time slot. The specific content and structure set in the first time slot are as follows; the synchronization code is placed at the beginning of the time slot, and then the signaling parameters.

[0042] Among them, the synchronization code is used for synchronization between the receiving end and the sending end;

[0043] Signaling parameters, used to establish...

Abstract

The invention discloses a voice transmission method and a voice transmission system which are applied to the technical field of digital interphone communication. The method comprises the following steps: bearing configured signaling parameters in a heat time slot of a voice superframe, wherein the signaling parameters comprise all parameters for establishing a voice call link; and sending the voice superframe. Due to the adoption of the method and the system, on the premise of not reducing the transmission performance of the system, the system cost can be reduced, the transmission efficiency of the system can be improved and the voice link flow of a receiving end can be optimized.

Description

technical field [0001] The invention relates to the technical field of special communication for wireless digital walkie-talkies, in particular to a voice transmission method and system. Background technique [0002] In the existing dmr voice superframe, except the voice header frame, each voice burst carries the same color code and private information parameters (such as figure 1 structure shown). [0003] Such as figure 2 As shown, the embedded signaling is set in the middle of each voice burst, and when the embedded signaling is set in each voice burst, specifically the embedded domain content (the embedded domain content specifically includes: color code, private information, Start and end instructions) are placed at both ends of the embedded signaling parameters; [0004] according to figure 1 In the voice superframe structure shown, after the receiving end obtains the voice header time slot, it analyzes the information carried in the entire voice header frame: ...
