The present invention discloses a method for terminals to switch among the reverse traffic channels in CDMA group call service. During the establishing procedure of the standard group call service, the originating call terminal sets the long code mask for the reverse dedicated traffic channel, establishes the reverse dedicated traffic channel and obtains the talk right to become the speaking terminal; the called terminal sets the long code mask for the reverse shared traffic channel, establishes the reverse shared traffic channel and becomes the listening terminal. After the speaking terminal successfully releases the talk right, it resets the long code mask of the reverse traffic channel as the long code mask of the reverse shared traffic channel and switches to the reverse shared traffic channel to become the listening terminal. After the listening terminal applies for and gets the talk right, it resets the long code mask of the reverse traffic channel as the long code mask of the reverse dedicated traffic channel and switches to the reverse dedicated traffic channel to become the speaking terminal. According to the present invention, in the standard group call service, the terminal of one group can rapidly switch to the corresponding reverse traffic channel when the status is changed.
