Sound rate mode 8, the path loss adjustment threshold value of eating dishes without rice or wine of voice rate mode 8 corresponding second is 70, current uplink radio link damage
Consumption 75 is greater than second and eats dishes without rice or wine path loss adjustment threshold value 70, then first terminal is reduced to voice rate mode using voice rate mode
7。
In one embodiment, call is established initial stage, and first terminal is in preferable signal environment, uplink radio link damage
Consumption maintains always 50 or less；In communication process, first terminal is mobile to the environment of dtr signal, up-link wireless chain during this
Path loss consumption constantly increases；First terminal continues to the worse environment movement of signal, and in this process, first terminal detects uplink
Radio Link loss continues to increase, and is greater than 70；The vocoder mode of transmission is reduced to by first terminal from broadband speech pattern 8
Broadband voice mode 7；At this point, detect by first terminal, uplink radio link loss is maintained within the scope of 75-80, call after
It is continuous to carry out.
