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
response to a network request for a PDP context activation.
When the
(
> 0) command is received, the MT will attempt to perform a GPRS attach if not yet
attached and if configured to do so (see
, parameter
). Failure will result in ERROR being
returned to the TE. 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 intermediate result code CONNECT. The MT then enters
V.250 online data state and follows the same procedure as it would after having received a
values specified.
=0 does not perform an automatic GPRS detach.

Parameter Description
000
(&F)
Disables automatic answer mode.
001-255
Enables automatic answering after specified number of rings.
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
• If 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 belongs
to the automatic context activation procedure. If the AT command which caused the collision was a CS data
call, the CONNECT response does not belong to this data call but to the GPRS. This can be detected if
is not set to 0. CS data call will issue CONNECT
• 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.
• The automatic GPRS attach will not be performed on recalling a stored user profile with
or on powerup,
if a n > 0 setting was stored in the user profile with
.
• If the automatic GPRS attach fails (e.g. the network rejects the attach request), the write command returns
error, though the new value takes effect. This is necessary because
is used for circuit switched calls too.
• ATS0 write command is PIN protected.
