Problems solved by technology

In the speech transmission of the wireless communication system, the speech superframe is usually used as the basic unit for transmission, and every six speech burst frames form a speech superframe, and the transmission of each speech superframe starts from the first speech burst Frame start (except for the first burst, the duration of each burst is 30ms), and the voice burst frame does not contain CCF, that is, a voice channel-associated signaling cannot be formed
Therefore, in the process of voice transmission, it is not conducive to quickly realize special functions such as late entry and forced demolition

Embodiment 1

[0022] The voice transmission method of the present embodiment includes the following steps:

[0023] 1) When a voice call is initiated, the voice transmitting end sends a voice start signaling to the voice receiving end, and then performs voice transmission with a voice superframe as the basic unit, and the voice superframe is composed of five voice burst frames;

[0024] 2) Insert a speech frame synchronization word FS1 and two channel-associated signaling fields CCF into the payload area of ​​each speech burst frame. The channel-associated signaling field CCF includes time slot type unit, channel direction unit, channel state unit, header unit and channel-associated signaling unit for embedding special signaling;

[0025] 3) A voice channel-associated signaling unit is composed of eight channel-associated signaling units in eight voice burst frames. Every time a voice superframe is transmitted, a voice channel-associated signaling is also transmitted to realize the special ...

Abstract

The invention discloses a voice transmission method based on channel associated signaling. The method comprises the following steps that: 1) a voice transmitting end transmits a voice start signaling to a voice receiving end when initiating voice call, and then, takes the voice superframe as the basic unit to execute voice transmission, wherein the voice superframe is composed of multiple voice burst frames; 2) a voice frame synchronization word FS1 and a channel associated signaling field (CCF) are inserted into an effective load region of each voice burst frame, wherein the CCF comprises a channel associated signaling unit; and 3) multiple channel associated signaling units form one voice channel associated signaling, one voice channel associated signaling is transmitted when each voice superframe is transmitted, so as to realize a special function needed for the voice transmission process, and after the voice is transmitted overall, the voice transmitting end transmits one voice ending signaling to the voice receiving end so as to end the voice transmission. According to the method provided by the invention, multiple channel associated signaling units form one voice channel associated signaling, and the functions, such as access delaying and forced releasing, can be finished.

Description

technical field [0001] The invention relates to a voice transmission method, in particular to a voice transmission method based on channel-associated signaling. It belongs to the technical field of wireless communication. Background technique [0002] Channel Associated Signaling (CAS: Channel Associated Signaling) refers to a signal method in which the signals of each voice channel are transmitted through the voice channel itself or through the signal channel corresponding to the voice channel. When channel associated signaling is used for voice transmission, Some special functions of voice transmission can be completed. [0003] With the development of wireless control technology and services, more and more functions are required by wireless terminal equipment. In the speech transmission of the wireless communication system, the speech superframe is usually used as the basic unit for transmission, and every six speech burst frames form a speech superframe, and the transm...
