11. Packet Domain related Commands
The AT commands described in this chapter allow the Customer Application to control packet switched services.
Please use chapter "Using GPRS AT commands (Examples)" as a first guidance.
11.1 AT+CGACT PDP context activate or deactivate
Syntax
Command Description
The test command is used for requesting information on the supported PDP context activation states.
The read command returns the current activation states for all the defined PDP contexts.
The write command is used to activate or deactivate the specified PDP context(s). After the command has com-
pleted, the MT remains in V.250 command state. If any PDP context is already in the requested state, the state
for that context remains unchanged. If the MT is not GPRS attached when the activation form of the command
is executed, the MT first performs a GPRS attach and then attempts to activate the specified contexts. If no
<cid>s are specified the activation/deactivation form of the command activates/deactivates all defined contexts.
If the MT is not able to activate a context because of a failed attach, the command returns "ERROR" or "+CME
ERROR: unknown" after 385 seconds (timer T3310 expired).
If the MT is attached but is not able to activate a context for more than 160 seconds (timer T3380 expired), com-
mand returns "ERROR" or "+CME ERROR: unspecified GPRS error". In this case AT+CEER returns "+CEER:
51,3,0".
The command should not be used to deactivate a PDP context during the implicit PDP context deactivation pro-
cedure which is started automatically after LCP termination or by dropping the DTR line (if AT&D2 is configured).
For details refer to Section 11.5.1, Automatic deactivation of PDP context during dial-up PPP.
