12.1.4. Quality of service profile (minimum acceptable) +CGQMIN<strong>DC3500</strong> <strong>AT</strong> <strong>Commands</strong> Reference <strong>Manual</strong> <strong>500242R01</strong>DescriptionThis command allows the TE to specify a QoS (Quality of Service) minimum acceptable profile whichis checked by the MT against the negotiated profile returned in the activate PDP context acceptmessage. The profile is identified by the parameter.Important note:For SUBSCRIBED = 0 given QMIN parameters are automatically mapped to minimal values.Reason:If the setting for +CGQMIN is with SUBSCRIBED = 0 there is no useful comparing possible of theparameters as SUBSCRIBED means: accept everything => setting 0 does not take any effect.SyntaxCommand syntax:<strong>AT</strong>+CGQMIN=[[,[,[,[,[,]]]]]]Command<strong>AT</strong>+CGDCONT isneeded previously<strong>AT</strong>+CGQMIN=1,1,1,1,1,1Read command<strong>AT</strong>+CGQMIN?Test command<strong>AT</strong>+CGQMIN=?Possible response(s)OKorCME ERROR: +CGQMIN:,,,,,OK+CGQMIN: “IP”,(0-3),(0-4),(0-5),(0-9),(0-18)i.e.+CGQMIN:,(list of supported s),(list of supporteds),(list of supported s),(list of supporteds),(list of supported s)[+CGQMIN:,(list of supported s) ,(list ofsupported s),(list of supported s),(list ofsupported s),(list of supported s)[...]]OK12.1.5. GPRS attach or detach +CG<strong>AT</strong>TDescriptionThis execution command is used to attach the MT to, or detach the MT from the GPRS service. Afterthis command the MT remains in command state. If the MT is already in the requested state, thecommand is ignored and OK is returned to TE. If the requested state can not be reached, an ERRORis returned. The command is abortable by hit a key; in this case a detach is performed (aborting is aproprietary feature). Any active PDP context will be automatically deactivated when the attachmentstate changes to detached.SyntaxCommand syntax: <strong>AT</strong>+CG<strong>AT</strong>T=[]Command<strong>AT</strong>+CG<strong>AT</strong>T=1Read command<strong>AT</strong>+CG<strong>AT</strong>T?Test command<strong>AT</strong>+CG<strong>AT</strong>T=?Possible response(s)OKorCME ERROR: +CG<strong>AT</strong>T: OK+CG<strong>AT</strong>T: (0-1)e.g.+CG<strong>AT</strong>T: (list of supported s)OKConfidential DAVISCOMMS (S) PTE LTD 124 /136

If the requested state can not be achieved, an ERROR isreturned. If the MT is not GPRS attached when the activation form of the command is executed, theMT first performs a GPRS attach and them attempts to activate the specified contexts.
