2.12. AT+CGDCONT Define the PDP Context
The write command specifies PDP context parameter values for a PDP context identified by the (local)
context identification parameter, <cid>. The number of PDP contexts that may be in a defined state at the
same time is given by the range returned by the test command.
For EPS the PDN connection and its associated EPS default bearer is identified herewith. For EPS the
<PDP_addr> shall be omitted.
A special form of the write command, +CGDCONT= <cid> causes the values for context number <cid> to
become undefined.
The read command returns the current settings for each defined context.
The test command returns values supported as a compound value. If the UE supports several PDP types,
<PDP_type>, the parameter value ranges for each <PDP_type> are returned on a separate line.
The feature "initial PDP context" may be supported and is a manufacturer specific option. For this option,
the context with <cid>=0 (context number 0) is defined upon startup and does not need to be created with
the +CGDCONT command. The initial PDP context has particular manufacturer specific default settings
disassociated with any other default settings of +CGDCONT. When in E-UTRAN, the initial PDP context is
automatically activated by the MT following a successful registration to the network depending on the
setting of AT+CIPCA command. If all active contexts are deactivated, the initial PDP context can be
(re)established. This is manufacturer specific and depends on the current RAT as well as how the active
contexts are deactivated.
