Short Message Service
 The Short Message Service comprise two basic
services
 SM MT (Short Message Mobile Terminated)
 SM MO (Short Message Mobile Originated)

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.

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.

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).

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)

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.

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.

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.

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

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. [email protected]).

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.

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.
