Air Interface Call Processing

Wickopedia had a pretty good basic description of the Um Interface and how a mobile phone originates and terminates a call on GSM. Is there anyone out there that can point me to a similar description for CDMA (IS95)?

I mean the step by step messages that are exchanged between the MS and the BS on a mobile originated call and a mobile terminated call.

For CDM2000 air interface messages, 3GPP2 specifications for access network interfaces can be referred.
CDMA Mobile Originated air interface messages include -
Origination(on access ch) MS->BS
BS Ack Order(on Paging ch)BS->MS
Channel Assignment(on paging ch)BS->MS
Tch Preamble(on reverse traffic ch) MS->BS
BS ack order(on forward trafic ch) BS->MS
MS Ack Order (on reverse trafic ch) MS->BS
Service connect(on forward traffic ch) BS->MS
Service connect complete(reverse traffic ch) MS->BS

Thank you for that document.

Would you have the complete documentation aside from Section F?

It would be a good reference.
