Slide 13: 

Messages in CDMA In CDMA, most call processing events are driven by messages Some CDMA channels exist for the sole purpose of carrying messages; they never carry user’s voice traffic Sync Channel (a forward channel) Paging Channel (a forward channel) Access Channel (a reverse channel) On these channels, there are only messages, continuously all of the time Some CDMA channels exist just to carry user traffic Forward Traffic Channel Reverse Traffic Channel On these channels, most of the time is filled with traffic and messages are sent only when there is something to do All CDMA messages have very similar structure, regardless of the channel on which they are sent
