Method for Improving Voice Call Quality, Terminal, and System

A terminal, comprising:

• a buffer comprising voice data;
• a processor coupled to the buffer;
• and
• a memory coupled to the processor and configured to store instructions that, when executed by the processor, cause the terminal to be configured to:
• receive a maximum allowable buffer duration from an apparatus, wherein the maximum allowable buffer duration limits a buffer duration for the voice data;
• buffer the voice data according to the maximum allowable buffer duration;
• determine that voice data is in an accumulated state;
• and
• cut off a first silence insertion descriptor (SID) frame in the voice data, wherein the first SID frame does not comprise semantic data.

A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a terminal to:

• receive a maximum allowable buffer duration from an apparatus, wherein the maximum allowable buffer duration limits a buffer duration for voice data of a buffer of the terminal;
• buffer the voice data according to the maximum allowable buffer duration;
• determine that the voice data is in an accumulated state;
• and
• cut off a first silence insertion descriptor (SID) frame of the voice data,
• wherein the first SID frame has no semantic data.
