When use wcdma module ,we should use ppp protocol to communicate with ppp server. But I can't see any file about ppp in N9's filesystem.

So,How N9 use linux(harmattan) to dial to PPP server and then linked to internet ?

Not really. GSM/WCDMA does not use PPP like IP over CS does. The connection is direct PS stream, imagine it's more like a WLAN connection than a "traditional" modem connection.

See 3gpp specs for more info; http://www.3gpp.org/specifications
