AMPS: Call Reception
idle phones continuously listen to the paging channel to
detect messages directed at them
when someone initiates call to mobile, message is sent
to home MTSO to find out where mobile currently is
a packet is then sent to base station in current cell,
which pages the mobile on the paging channel
if mobile replies, base assigns channel number and
sends it to mobile
mobile switches to this channel and starts making
ringing sound
