Short Message Service • The Short Message Service comprise two basic services • SM MT (Short Message Mobile Terminated) • SM MO (Short Message Mobile Originated) 行動通訊簡訊及多媒體訊息

Basic Services:SM-MT and SM-MO 行動通訊簡訊及多媒體訊息

Short Message Service elements • The SMS comprises 7 elements • Validity-Period • Service-Centre-Time-Stamp • Protocol-Identifier • More-Messages-to-Send • Priority • Messages-Waiting • Alert-SC 行動通訊簡訊及多媒體訊息

Short Message Service elements • Validity-Period • The Validity-Period is the information element which gives an MS submitting an SMS-SUBMIT to the SC the possibility to include a specific time period value in the short message. 行動通訊簡訊及多媒體訊息

Short Message Service elements • Service-Centre-Time-Stamp; • The Service-Centre-Time-Stamp is the information element by which the SC informs the recipient MS about the time of arrival of the short message at the SM-TL entity of the SC. 行動通訊簡訊及多媒體訊息

Short Message Service elements • Protocol-Identifier • The Protocol-Identifier is the information element by which the SM-TL either refers to the higher layer protocol being used, or indicates interworking with a certain type of telematic device. • The Protocol-Identifier information element makes use of a particular field in the message types • SMS-SUBMIT, • SMS-SUBMIT-REPORT for RP-ACK • SMS-DELIVER DELIVER • SMS-DELIVER-REPORT for RP-ACK • SMS_STATUS_REPORT • SMS-COMMAND TP-Protocol-Identifier (TP-PID). 行動通訊簡訊及多媒體訊息

Short Message Service elements • More-Messages-to-Send • The More-Messages-to-Send is the information element by which the SC informs the MS that there is one or more messages waiting in that SC to be delivered to the MS. • The More-Messages-to-Send information element makes use of a Boolean parameter in the message • SMS-DELIVER • TP-More-Messages-to-Send (TP-MMS) 行動通訊簡訊及多媒體訊息

Short Message Service elements • Priority • Priority is the information element provided by an SC or SME to indicate to the PLMN whether or not a message is a priority message. 行動通訊簡訊及多媒體訊息

Short Message Service elements • Messages-Waiting • The Messages-Waiting is the service element that enables the PLMN to provide the HLR, SGSN and VLR with which the recipient MS is associated with the information that there is a message in the originating SC waiting to be delivered to the MS. • Messages-Waiting-Indication (MWI) • Messages-Waiting-Data (MWD) • The Mobile-station-Not-Reachable-for-GPRS (MNRG) • The Mobile-Station-Not-Reachable-Flag (MNRF) • The Mobile-Not-Reachable-Reason (MNRR) • The Mobile-Station-Memory-Capacity-Exceeded-Flag (MCEF) located in the HLR • The Mobile-station-Not Reachable-for-GPRS (MNRG) located in the SGSN • The Mobile-Station-Not-Reachable-Flag (MNRF) located in the VLR. 行動通訊簡訊及多媒體訊息

Short Message Service elements • Messages-Waiting 行動通訊簡訊及多媒體訊息

Short Message Service elements • Alert-SC • The Alert-SC is the service element, which may be provided by some GSM/UMTS PLMNs, to inform the SC that an MS 1) to which a delivery attempt has failed because the MS is not reachable or because the MS memory capacity was exceeded and 2) which is now recognized by the PLMN: a) to have resumed operation (e.g. to have responded to a paging request) or b) to have memory newly available (which implies that the mobile is reachable). is again ready to receive one or more short messages. • The SC may - on reception of an Alert-SC - initiate the delivery attempt procedure for the queued messages destined for this MS. 行動通訊簡訊及多媒體訊息

Status Report Capabilities • The SMS also offers to the SC the capabilities of informing the MS of the status of a previously sent mobile originated short message. • The status of the message can be: • Successfully delivered to the SME • The SC was not able to forward the message to the SME 行動通訊簡訊及多媒體訊息

SMS and Internet Electronic Mail interworking • The interworking between Internet electronic mail and SMS is offered in both directions which enables new and old mobiles to send/receive Internet electronic mails via SMS. • The interworking is according to the following procedures: • An SMS message which is required to interwork with Internet email may have its TP-PID value set for Internet electronic mail; • Either single or concatenated SMS can be used to transport the email; • Concatenation may be achieved by the TPUDH mechanism. Alternatively, concatenation may be achieved using the text-based means described below; • Email cc fields are not supported; • Where multiple fields are present, additional spaces may be inserted by the sender to improve presentation of the message. Spaces may not be inserted into the actual email address (e.g. user@domain1.domain2). 行動通訊簡訊及多媒體訊息

Enhanced Messaging Service • The Enhanced Messaging Service (EMS) is based upon the standard SMS, but with formatting added to the text. • The formatting may permit the message to contain • Animations • Predefined • User Defined • Extended Animations • Pictures • Basic Pictures • Extended Pictures • Melodies • Predefined • User Defined • Extended Sounds • Formatted text • vCard • vCalendar • WVG objects. 行動通訊簡訊及多媒體訊息

Basic Network Structure SME(Short Message Entity): An entity may receive or send short messages. The SME may be located in a fixed network, an MS or an SC. 行動通訊簡訊及多媒體訊息
