【资料目录和简介】：

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
