1 Scope
The present document gives guidance on the network architecture and functionality to support a Point-Point Short
Message Service (PP-SMS) feature to users access network services via PSTN, ISDN, PLMN and IP as it is defined in
DES/SPAN-110093 (see Bibliography).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in GSM 09.02 [1] apply.
msIsdn: this parameter refers to one of the ISDN numbers assigned to a mobile subscriber in accordance with CCITT
Recommendation E.213 [3]
sm-RP-PRI: this parameter is used to indicate whether or not delivery of the short message shall be attempted when a
service centre address is already contained in the Message Waiting Data file
ServiceCentreAddress: this parameter represents the address of a Short Message Service Centre
Sm-RP-UI: this parameter represents the user data field carried by the short message service relay sub-layer protocol
MoreMessagesToSend: this parameter is used to indicate whether or not the service centre has more short messages to
send
MwStatus: this parameter indicates whether or not the address of the originator service centre is already contained in
the Message Waiting Data file. In addition, it contains the status of the Memory Capacity Exceeded Flag (MCEF) and
the status of the Mobile subscriber Not Reachable Flag (MNRF)

4 uSMS service requirements
The uSMS service requirements are specified in DES/SPAN-110093 (see Bibliography).
In line with the HLR in GSM networks, the supporting network shall have some predefined data fields for uSMS
parameters. For example,
The HLR contains (optional):
• Message Waiting Data (MWD):
- MSIsdn-Alert;
- SC address 1;
- SC address 2;
-…;
- SC address n;
• Mobile Not Reachable Flag (MNRF);
• Mobile Station Memory Capacity Exceeded Flag (MCEF).
The VLR contains (optional):
• Mobile Not Reachable Flag (MNRF).
The case where MWD, MNRF and MCEF are not implemented in the HLR is also described in GSM 03.40 [2].

5 uSMS Functional Architecture
5.1 ISDN/IN Infrastructure
This section describes the architecture for uSMS based on an ISDN/IN suporting infrastructure. It covers these cases
where the user is in his/her home network or in a visited network. The implementation of uSMS should deliver the SMS
with the same (or higher) QoS as for the GSM SMS.

5.2 Packet Service Infrastructure
This is for further study.
6 Point-Point uSMS Procedures and Information Flows
This section displays for each procedure information flows; the mapping of these flows to specific protocol messages is
outside the scope of the present document.
The following procedures are relevant for the uSMS service:
• Short Message terminal originated (normal and exception procedure);
• Short Message terminal terminated (normal and exception procedure);
• Short Message delivery notification.
NOTE: In the present document the SMS is defined following the GSM procedures (i. e. it is assumed that the
terminals are able to store SMS messages).

6.1 Terminal originated uSMS normal transfer procedure
In the terminal originated case, a short message is sent from the terminal (portable or fixed) towards the short message
service centre. This short message is sent along with the E.164 [4] number of the recipient, and possibly the Calling
Line Identity of the originating terminal (CLI) in case the recipient should receive this information as in the GSM SMS
service. The CLI may be replaced by the calling user number e.g. in the case of virtual calling card, UPT.

NOTE 1: In order to retrieve and check the SMS access rights of the user, when the user originates a uSMS
procedure, the SCFh queries the SDFh.
NOTE 2: Another possibility could be to use serviceCentreAddress, and forward the short message directly to the
IWU, and bypass the SCFsl.
