Quality Of Service Profile Requested +Cgqreq - Multitech MMCModem GPRS (MTMMC-G) Reference Manual

Quality of Service Profile Requested +CGQREQ

Description:
This command allows the DTE to specify a Quality of Service Profile that is used when the modem
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 modem supports several PDP types, the parameter value
ranges for each PDP type are returned on a separate line.
