request for PDP context activation announced by the unsolicited result c ode
RING
or
+CRING: GPRS <PDP_type>,<PDP_addr>
The MT responds with
OK
Reference
GSM 07.07
Note
• In contrast to GSM 07.07 it is possible to cancel a connection with ATH after
a break. This is done for compatibility reasons due to the “dial-up network“
(“DFÜ-Netzwerk“) drivers of Microsoftã Windowsâ.
• ATH is used as a standard V.25ter AT Command, too. See Chapter 2.12.
Using ATH while GPRS is active (PDP context is activated or online):
• CAUTION: The execution of ATH cancels an active PDP context. This tak es
effect no matter whether ATH was used to end a voice or data (CSD) call, to
manually reject a network requested PDP context activation as describ ed
above or to terminate a call on one of the virtual channels in Mu ltiplex mode.
The context deactivation can be avoided by terminating a current call with
AT+CHLD=1 instead of ATH. See Chapter 4.16 for AT+CHLD.
