3.13. AT+CGDCONT Define PDP Context
The set command specifies PDP context parameter values for a PDP context identified by <cid>, the
(local) context identification parameter, and also allows the TE to specify whether security protected
transmission of ESM information is requested, because the PCO can include information that requires
ciphering. There can be other reasons for the UE to use security protected transmission of ESM
information, e.g. if the UE needs to transfer an APN. 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. Refer to Chapter 6 for
possible <err> values.
For EPS, the PDN connection and its associated EPS default bearer is identified herewith.
A special form of the set command, +CGDCONT=<cid> causes the values for context number <cid> to
become undefined.
If the initial PDP context is supported, the context with <cid>=0 is automatically defined at startup, please
refer to 3GPP TS 27.007 V13.5.0, subclause 10.1.0. As all other contexts, the parameters for <cid>=0 can
be modified with +CGDCONT. If the initial PDP context is supported, +CGDCONT=0 resets context
number 0 to its particular default settings.
The read command returns the current settings for each defined context.
The test command returns values supported as compound values. If the MT supports several PDP types,
the parameter value ranges for each <PDP_type> are returned on a separate line.
