MWD consists of an address list of the SCs which have messages waiting to be delivered to the MS.Mobile-services Switching Centre (MSC): The Mobile-services Switching Centre is an exchange which performs switching functions for mobile stations located in a geographical area designated as the MSC area.Mobile-Station-Memory-Capacity-Exceeded-Flag (MCEF): A part of the MWI to be stored in the HLR. MCEF is a Boolean parameter indicating if the address list of MWD contains one or more entries because an attempt to deliver a short message to an MS has failed with a cause of MS Memory Capacity Exceeded.Mobile-Station-Not-Reachable-Flag (MNRF): The part of the MWI to be stored in the VLR and the HLR. MNRF is a Boolean parameter indicating if the address list of MWD contains one or more entries because an attempt to deliver a short message to an MS has failed with a cause of Absent Subscriber.Mobile-station-Not-Reachable-for-GPRS (MNRG): The part of the MWI to be stored in the SGSN and the HLR. MNRG is a Boolean parameter indicating if the address list of MWD contains one or more entries because an attempt to deliver a short message to an MS has failed with a cause of Absent Subscriber.Mobile-Station-Not-Reachable-Reason (MNRR): The part of the MWI in the HLR which stores the reason for an MS being absent when an attempt to deliver a short message to an MS fails at the MSC with a cause of Absent Subscriber.More-Messages-To-Send (MMS): Information element offering an MS receiving a short message from an SC the information whether there are still more messages waiting to be sent from that SC to the MS. The TP-MMS element (conveyed in the Transfer layer) is copied into the RP-MMS element (conveyed in the Relay layer). It is possible with Phase 2 and later versions of MAP (3GPP TS 29.002 [15]) for the RP-MMS element to keep an SM transaction open between the GMSC and the MS in the case where there are more-messages-to-send. Earlier versions of MAP support the transport of theTP-MMS element.priority: Service element enabling the SC or SME to request a short message delivery attempt to an MS irrespective of whether or not the MS has been identified as temporarily absent.protocol-identifier: Information element by which the originator of a short message (either an SC or an MS) may refer to a higher layer protocol.reply path procedure: A mechanism which allows an SME to request that an SC should be permitted to handle a reply sent in response to a message previously sent from that SME to another SME. This may happen even though the SC may be unknown to the SME which received the initial message.report: Response from either the network or the recipient upon a short message being sent from either an SC or an MS. A report may be a delivery report, which confirms the delivery of the short message tothe recipient, or it may be a failure report, which informs the originator that the short message was never delivered and the reason why.When issued by the Service Centre, the delivery report confirms the reception of the ShortMessage by the SC, and not the delivery of the Short Message to the SME.When issued by the Mobile Station, the delivery report confirms the reception of the ShortMessage by the Mobile Station, and not the delivery of the Short Message to the user.replace short message type: A range of values in the Protocol Identifier which allows an indication to be sent with a short message (MT or MO) that the short message is of a particular type allowing the receiving MS or the SC to replace an existing message of the same type held in the SC, the ME or on the SIM / UICC, provided it comes:- in MT cases: from the same SC and originating address;- in MO cases: from the same MS.Service Centre (SC): Function responsible for the relaying and store-and-forwarding of a short message between an SME and an MS. The SC is not a part of the GSM/UMTS PLMN, however MSC and SC may be integrated.（短信业务中心，主要就是在SME和MS之间层递，存储转发短信，一般情况下他时短消息数据库）。
