Request GPRS IP Service: ‘D’
Description: This command causes the MT to perform whatever actions are necessary to
establish communication between the TE and the external PDN. The V.25ter ‘D’ (Dial) command
causes the MT to enter the V.25ter online data state and, with the TE, to start the specified layer 2
protocol. The MT return CONNECT to confirm acceptance of the command prior to entering the
V.25ter online data state. No further commands may follow on the AT command line.
The detailed behavior after the online data state has been entered is described briefly in
clause 9, for IP, of GSM 07.60. GPRS attachment and PDP context activation procedures may take
place prior to or during the PDP startup if they have not already been performed using the
+CGATT and +CGACT commands.
If <cid> is supported, its usage is the same as in the +CGDATA command. The
+CGDCONT, +CGQREQ, etc., commands may then be used in the modem initialization AT
command string to set values for PDP type, APN, QoS, etc.
If <cid> is not supported or is supported but omitted, the MT attempt to activate the
context using the ‘Empty PDP type’ (GSM 04.08). (No PDP address or APN is sent in this case
and only one PDP context subscription record is present in the HLR for this subscriber.)
Note: If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is
not supported.
