GPRS commands 235 6615-2220
+CGAUTO – Automatic response to a network request for PDP
context activation
Description:
The set command disables or enables an automatic positive response (auto-answer)
to the receipt of a Request PDP Context Activation message from the network. It also
provides control over the use of the V.25ter basic commands 'S0', 'A and 'H' for handling
network requests for PDP context activation. The setting does not affect the issuing of
the unsolicited result code RING or +CRING.
The test command returns values of <n> supported by the MT as a compound value.
When the +CGAUTO=0 command is received, the MT will not perform a GPRS detach
if it is attached. Subsequently, when the MT announces a network request for PDP
context activation by issuing the unsolicited result code RING or +CRING, the TE may
manually accept or reject the request by issuing the +CGANS command or may simply
ignore the network request.
When the +CGAUTO=1 command is received, the MT will attempt to perform a GPRS
attach if it is not already attached. Failure will result in ERROR or, if enabled, +CME
ERROR being returned to the TE. Subsequently, when the MT announces a network
request for PDP context activation by issuing the unsolicited result code RING or
+CRING to the TE, this is followed by the intermediate result code CONNECT. The MT
then enters V.25ter online data state and follows the same procedure as it would after
having received a +CGANS=1 with <cid> values specified.
