8.12 AT+CGEQREQ 3G quality of service profile (requested)
Description
The test command returns values supported as a compound value.
The read command returns the current settings for each defined context for which a QOS was
explicitly specified.
The write command allows the TE to specify a Quality of Service Profile for the context identified
by the context identification parameter <cid> which is used when the MT sends an Activate PDP
Context Request message to the network.
A special form of the write command, AT+CGEQREQ=<cid> causes the requested profile for
context number <cid> to become undefined.
