13.6.1î™–î™–î™–î™–Description
Activates or deactivates the specified PDP context. After the command, the MT remains in AT command mode.
If any context is already in the requested state, the state for the context remains unchanged. If the required
action cannot succeed, an error result code is returned. If the MT is not GPRS attached when the activation of
a PDP context is required, the MT first performs a GPRS attach and then attempts to activate the specified
context.
The maximum expected response time is different whenever the activation or the deactivation of a PDP context
is performed (150 s and 40 s respectively).
The command can be aborted if a character is sent to the DCE during the command execution: if a PDP context
activation on a specific <cid> was requested, the PDP context deactivation is performed; if a multiple PDP
context activation was requested, it is aborted after the pending PDP context activation has finished.
The deactivation action is carried out even if the command is aborted.
