B.3 Service-level interworking: IP-SM-GW informs SMS users about group chat participant changes
23.2043GPPRelease 17Stage 2Support of Short Message Service (SMS) over generic 3GPP Internet Protocol (IP) accessTS
In this flow, the IP-SM-GW is in the PLMN of the CPM UE, but it could also be in the PLMN of the SMS user if that user was also a CPM user and had terminating user preferences to deliver the session invitation via SMS.
Figure B.3: Sending participant information changes to an SMS user in a group chat session
1) A group chat session including SMS user(s) set up by an IM or CPM user as described in clause B.1 steps 1-17.
2) The group chat AS detects change in participants of the group chat session (e.g. participant added or left the group chat session, that event is not shown in the flow).
3-4) As the IP-SM-GW has subscribed to participant information changes, the group chat AS notifies the IP-SM-GW about the participant change through the S-CSCF using an appropriate SIP method.
5-6) The IP-SM-GW acknowledges the notification.
7) According to operator policy, the IP-SM-GW translates the participant change notification to a Short Message (SMS- SUBMIT) and forwards it towards the group chat SMS-SC (SC Address) via the SMS-IWMSC (as described in TS 23.040 [2]). The text in the Short Message is defined by the operator and conveys appropriate information to the SMS user.
8) The SMS-IWMSC forwards the Short Messages (SMS- SUBMIT) to the group chat SMS-SC and the SMS is delivered to the SMS user using standard SMS procedures (see TS 23.040 [2]).
