Gateway MSC For Short Message Service (SMS-GMSC):

function of an MSC capable of receiving a short message from an SC, interrogating an HLR/HSS/UDM for routing information and SMS info, and delivering the short message to the VMSC/SGSN/MME/SMSF of the recipient MS/UE.

Interworking MSC For Short Message Service (SMS-IWMSC):

function of an MSC capable of receiving a short message from within the PLMN and submitting it to the recipient SC.

IP-Short-Message-Gateway (IP-SM-GW):

function responsible for protocol interworking between the IP-based UE and the SC.

Service Centre (SC):

function responsible for the relaying and store and forwarding of a short message between an SME and an MS/UE.
