Patent ID: 8194620

Claim:
A method for terminals to switch among reverse traffic channels in a group call service in CDMA system, comprising following steps: (a) during establishing procedure of a standard group call service, an originating call terminal sets a long code mask of a reverse traffic channel as a long code mask of a reverse dedicated traffic channel, establishes the reverse dedicated traffic channel and obtains talk right to become a speaking terminal; a called terminal sets a long code mask of a reverse traffic channel as a long code mask of a reverse shared traffic channel, establishes the reverse shared traffic channel and becomes a listening terminal; (b) 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 for switching 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 for switching to the reverse dedicated traffic channel to become the speaking terminal.
