ATS0 Automatic response to a network request for PDP context
activation
The V.250
(Automatic answer) command may be used to turn off (n=0) and on (n>0) the automatic
ATS0=<n>
response to a network request for a PDP context activation. See also
mand set for User Equipment
When the
ATS0=<n> (<n>
attached and if configured to do so (see AT^SCFG, parameter <gs0aa>). Subsequently, the MT will announce
a network request for PDP context activation by issuing the URC RING or CRING to the TE, followed by the inter-
mediate result code CONNECT. The MT then enters V.250 online data state and follows the same procedure as
it would after receiving a AT+CGANS=1 command with no
ATS0=0 does not perform an automatic GPRS detach.

Notes
•
If different settings are used on each interface, and a request for PDP context activation is received, the inter-
face 'wins' which is idle and uses the smallest
•
When a network request for PDP context activation is answered automatically and another AT command is
issued at the same time on the same interface then this AT command will not be executed. Any response
relates to the automatic context activation procedure. If the AT command which caused the collision was a
CS data call, the CONNECT response does not pertain to this data call but to GPRS. This can be detected if
is not set to 0. The CS data call will issue CONNECT <text>, GPRS will issue CONNECT only.

•
A network request for PDP context activation has a maximum duration of approximately 40 seconds (for
details see GSM 04.08). A RING/CRING URC is issued every 5 seconds, so setting parameter
greater than 7 will not allow a successful context activation and is not recommended.
•
Automatic GPRS attach will not be performed on recalling a stored user profile with
though a value
greater than 0 was stored in the user profile with AT&W.
