とを確認する。Referring to FIG. 1 showing an embodiment of the present invention, the mobile station 2 on the control channel of the radio base station 1 is the mobile station 3
When making a call to, the connection request signal 4 is transmitted on the control channel. Upon receiving this connection request signal 4, the radio base station 1 sends out a connection instruction signal 5 to the mobile device 2 on the control channel. Upon receiving the connection instruction signal 5, the mobile device 2 switches to the instructed speech channel and then sends out radio waves on the speech channel. The radio base station 1 receives this radio wave to confirm that the mobile device 2 has correctly switched to the call channel. The radio base station 1, which confirms that the mobile device 2 has correctly switched to the call channel, then sends out the call signal 6 to the mobile device 3 on the control channel. When the mobile device 3 receives the call signal 6, it returns a call response signal 7 on the control channel. By receiving the call response signal 7, the radio base station 1 confirms that the mobile device 3 is on its own control channel. The radio base station 1 which confirms that the mobile device 3 is on the control channel of the own station
Next sends a radio wave transmission stop instruction signal 8 to the mobile device 2 on the call channel. The mobile device 2 that has received the radio wave transmission stop instruction signal 8 stops the transmission of radio waves on the communication channel. The radio base station 1 confirms that the mobile device 2 has stopped transmitting radio waves because it cannot receive radio waves from the mobile device 2.

Upon receiving the connection instruction signal 9, the mobile device 3 switches to the instructed call channel and then sends out radio waves on the call channel. By receiving this radio wave, the wireless base station 1 confirms that the mobile device 3 has correctly switched to the call channel. The radio base station 1 which confirms that the mobile device 3 has correctly switched to the call channel sends the call connection completion signals 10 and 11 to the mobile devices 2 and 3. Call connection completion signal 10
The mobile device 2 that receives the call sends a ringing tone, and the mobile device 3 that receives the call connection completion signal 11 stops the transmission of radio waves and sends a ringing tone.

可能な状態となる。By performing the off-hook operation, the mobile device 3 starts transmitting radio waves again. Upon confirming that the mobile device 3 has gone off-hook by receiving the radio wave from the mobile device 3, the radio base station 1 sends out call start signals 12 and 13 to the mobile devices 2 and 3. The mobile unit 2 which has received the call start signal 12 stops the sending of the ringing tone and becomes ready for a call by the press-to-talk method, and the mobile unit 3 which has received the call start signal 13
Stops sending the ringing tone, stops the electric wave being sent off-hook, and becomes ready to talk by the press-to-talk method.
