7.5 Short Message network storage

23.1423GPPInterface and signalling flowRelease 17TSValue-added Services for SMS (VAS4SMS)

The short message storage can be active to both originating and terminating user.

Figure 7.5-1 Originating signaling flow – Short Message storage

NOTE: The VAS4SMS message in operation 4 is the same as the original SM.

1-3. See general flow described in the previous clause 7.0. The VAS AS A checks that a originating user has activated short message network storage service and indicates to the SMS Node A there is originating VAS active.

4. The VAS AS A decides that the original SMS shall be stored based on originating user’s preferences.

5-9. The VAS AS A delivers the original short message to the terminating user. See general flow described in the previous clause 7.0.

10. VAS AS A stores the original SMS and relevant information for originating user.

11. The VAS AS A generates a delivery report for the original short message based on the report which received in step 9 and sends to SMS Node A.

12. The SMS Node A sends the status report to UE, which is optional depending on user’s request.

Figure 7.5-2 Terminating signaling flow – Short Message storage

NOTE 1: The VAS4SMS message in operation 5 is the same as the original SM.

NOTE 2: Depending on the stage 3 protocol used, for VAS services where step 12 exceeds the allowed response time, a report of delivery status may be returned after step 4. This does not inform SMS Node A of the actual delivery outcome. Depending on the capabilities of the stage 3 protocol PLMN A may request a separate delivery report to be informed of the final delivery status.

1-4. See general flow described in the previous clause 7.0. The VAS AS B checks that a terminating user has activated short message network storage service and indicates to the SMS Node B that the terminating VAS is active.

5. The VAS AS B decides that the original SMS shall be stored based on terminating user’s preferences.

6-9.The VAS AS B delivers the original short message to the terminating user. See general flow described in the previous clause 7.0.

10. The VAS AS B stores the SMS and relevant information for terminating user.

11. The VAS AS B generates a report of the short message and sends it to SMS Node B.

12. The SMS Node B notifies the originating side of the delivery status.
