no. 1 example

[0043] In the first embodiment of the present invention, a method for improving voice communication quality, such as figure 1 shown, including the following specific steps:

[0044] Step S101, analyzing the message to be sent.

[0045] Step S102, according to the analysis result of the message to be sent, when the first stage adopts the first compression method to compress and send the message to be sent, and after the number of compressed messages reaches the preset threshold, the next message to be sent is processed in the second stage The sending message is compressed and sent using the second compression method.

[0046] Wherein, the cyclic redundancy check length of the first compression mode is smaller than the cyclic redundancy check length of the second compression mode.

[0047] For example: according to the analysis result of the message to be sent, when the compression method with 3-bit cyclic redundancy check or 7-bit cyclic redundancy check is used in the first ...

[0050] In the second embodiment of the present invention, a method for improving voice communication quality, such as figure 2 shown, including the following specific steps:

[0051] Step S201, analyzing the message to be sent.

[0052] Step S202, according to the analysis result of the message to be sent, choose the first method to compress and send the message to be sent, or choose the second method to compress and send the message to be sent.

[0053]Among them, the first method is to compress and send the message to be sent by using the first compression method in the first stage, and after the number of compressed messages reaches the preset threshold, use the first compression method for the next message to be sent in the second stage. Two compression methods to compress and send.

[0054] The second method is that when the second compression method is used to compress and send the message to be sent in the first stage, only the first message to be sent is compressed ...

[0061] In the third embodiment of the present invention, a method for improving voice communication quality includes the following specific steps:

[0062] Step S301, analyzing the message to be sent.

[0063] Step S302, according to the analysis result of the message to be sent, choose the first method to compress and send the message to be sent, or choose the second method to compress and send the message to be sent.

[0064] Among them, the first method is when the compression method with the first type of cyclic redundancy check is used to compress and send the message to be sent, and the number of compressed messages of the first type of cyclic redundancy check reaches the preset first When the threshold is reached, use the compression method with the third type of cyclic redundancy check to compress and send the message to be sent; or use the compression method with the second type of cyclic redundancy check to compress and send the message to be sent , and when the num...

Abstract

The present invention proposes a method and device for improving the quality of voice communication. The method includes: when the first stage uses the first compression method to compress and send the message to be sent, and after the number of compressed messages reaches the preset threshold, In the second stage, the next message to be sent is compressed and sent using the second compression method; the cyclic redundancy check length of the first compression method is smaller than the cyclic redundancy check length of the second compression method. The method and device for improving the quality of voice communication in the present invention overcomes the defect that the cyclic redundancy check in the compressed message is unreliable for the verification of the compressed message in the existing voice communication technology, and effectively improves the quality of the compressed message. The effectiveness of the cyclic redundancy check on the compressed message, thereby effectively improving the quality of voice communication.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for improving the quality of voice communication. Background technique [0002] Currently, in the technical field of voice communication, in order to make full use of the bandwidth, ROHC (RObust Header Compression, header compression) is used to compress the protocol header in the voice communication service message. The header compression technology related to the voice communication service includes: profile4 can compress IP (Internet Protocol, the protocol for interconnecting between networks) protocol header, profile2 can compress IP / UDP (User Datagram Protocol, User Datagram Protocol) protocol header and profile1 can compress Compress IP / UDP / RTP (Real-time Transport Protocol, real-time transport protocol) protocol header. [0003] Among them, some compressed messages have 3bitCRC (Cyclic Redundancy Check, cyclic redundancy check) messages, some c...
