AT+CMMS command

Hello, there is an AT command, AT+CMMS, wich description I report below: "This  command controls the continuity of SMS relay protocol link.   When feature is enabled (and supported by network) multiple messages can besent much faster as link is kept open." I tested this command on motorola E770 (UMTS) and really when I enable this feature it is much faster in sending sms. Is it possible to implent such feature  in application "mobile" of osmocom-bb project?
