Description
This command specifies PDP context parameter values for a PDP context identified by
the local context identification parameter, <cid>.
Eleven PDP contexts can be defined through Wavecom software.
A special form of the set command, +CGDCONT= <cid> causes the values for context
number <cid> to become undefined.
The test command returns values supported as a compound value. If the MT supports
several PDP types, <PDP_type>, the parameter value ranges for each <PDP_type> are
returned on a separate line.
The read command returns the current settings for each defined context.
The test command returns values supported as a compound value. If the MT supports
several PDP types, <PDP_type), the parameter value ranges for each <PDP_type> are
returned on a separate line.
Defined values
<cid>: (PDP Context Identifier) a numeric parameter (1-32) which specifies a particular
PDP context definition. The parameter is local to the TE-MT interface and is used in
other PDP context-related commands.
<PDP_type>: (Packet Data Protocol type) a string parameter which specifies the type of
packet data protocol
IP Internet Protocol
PPP Point to Point Protocol
<APN>: (Access Point Name) a string parameter, which is a logical name that is used to
select the GGSN or the external packet data network.
If the value is null or omitted, then the subscription value will be requested.
Description
This command allows the TE to specify a Quality of Service Profile that is used when
the MT sends an Activate PDP Context Request message to the network.
The set command specifies a profile for the context identified by the local context
identification parameter, <cid>. Since this is the same parameter that is used in the
+CGDCONT command, the +CGQREQ command is effectively an extension to the
+CGDCONT command. The QoS profile consists of a number of parameters, each of
which may be set to a separate value.
A special form of the set command, +CGQREQ= <cid> causes the requested profile 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 MT supports
several PDP types, the parameter value ranges for each PDP type are returned on a
separate line.
