Processing method for realizing forcibly inserting signaling into voice conversation

Abstract

The invention relates to a processing method for realizing forcibly inserting a signaling into a voice conversation. The method comprises the following steps: firstly, compressing voice in a digital mode so that the transmission rate thereof is less than the bandwidth of a wireless channel; then segmenting the voice, carrying out time division treatment on the wireless channel, organizing the spare bandwidth of the wireless channel and the voice in a form in accordance with the predefined frame, and sending into the air asynchronously or in a mode of being synchronous with transmitting equipment which runs at the moment; adopting a carrier sense mode to acquire an air wireless signal by a receiving party, carrying out synchronization by utilizing the air wireless signal, and resolving transmitted shunting instruction information, wherein the shunting command is the signaling; and enabling the signaling and the voice to utilize different channels in the frame, thus realizing forcibly inserting the signaling. The invention has the following advantages: the voice and the signaling are ensured not to conflict with each other; the voice and the shunting signaling operate in non-conflicting communication modes; when the voice is used, the signaling can be forcibly inserted, thus ensuring that the voice and the shunting operation can be carried out synchronously and the shunting signaling can not be lost due to signaling transmission and voice conversation.

Description

Technical field [0001] The invention relates to the field of train wireless plane shunting communication equipment, and in particular to a processing method for realizing the forcible insertion of signaling into a voice call. The method is used in train wireless plane shunting communication. Background technique [0002] In plane shunting operations, wireless plane shunting equipment has gradually replaced the original lights and flags and has become an effective tool for shunting. However, in the existing shunting equipment, due to the analog format of the equipment, the shunting signaling transmission and the voice call are often not synchronized, so that the shunting signaling cannot be received while sending the voice. Therefore, the shunting signaling may be caused. The order is lost, and will cause trouble in using the plane shunting equipment. Summary of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a technical sol...
