M.3.1 Procedures at the UE

M.3.1.1 3GPP PS data off

M.3.1.1.1 General

The requirements in clause J.3.1.1.1 apply.

Additionally, the following requirements apply.

In case of SNPN, if the UE supports the 3GPP PS data off:

a) the UE can be configured with:

1) up to two indications of whether the MMTEL voice is a 3GPP PS data off exempt service for each subscribed SNPN whose entry exists in the "list of subscriber data", one indication is valid for the UE camping in the subscribed SNPN, and the other indication is valid for any non-subscribed SNPN the UE is camping in using the subscribed SNPN’s credentials;

2) up to two indications of whether the MMTEL video is a 3GPP PS data off exempt service for each subscribed SNPN whose entry exists in the "list of subscriber data", one indication is valid for the UE camping in the subscribed SNPN, and the other indication is valid for any non-subscribed SNPN the UE is camping in using the subscribed SNPN’s credentials;

3) an indication of whether the MMTEL voice is a 3GPP PS data off exempt service for PLMN subscription, valid for any non-subscribed SNPN the UE is camping in using the PLMN subscription; and

4) an indication of whether the MMTEL video is a 3GPP PS data off exempt service for PLMN subscription, valid for any non-subscribed SNPN the UE is camping in using the PLMN subscription;

b) for a subscribed SNPN whose entry exists in the "list of subscriber data", the UE may support being configured with the indication of whether the MMTEL voice is a 3GPP PS data off exempt service using one or more of the following methods:

1) the MMTEL_voice_exempt node of 3GPP TS 24.275 [36], if the UE is in the subscribed SNPN; and

2) the MMTEL_voice_exempt_non_subscribed_SNPN node of 3GPP TS 24.275 [36], if the UE is in the non-subscribed SNPN.

For PLMN subscription, the UE may support being configured with the indication of whether the MMTEL voice is a 3GPP PS data off exempt service using the following method:

1) the MMTEL_voice_exempt_non_subscribed_SNPN node of 3GPP TS 24.275 [36], if the UE is in the non-subscribed SNPN; and

c) for a subscribed SNPN whose entry exists in the "list of subscriber data", the UE may support being configured with the indication of whether the MMTEL video is a 3GPP PS data off exempt service using one or more of the following methods:

1) the MMTEL_video_exempt node of 3GPP TS 24.275 [36], if the UE is in the subscribed SNPN; and

2) the MMTEL_video_exempt_non_subscribed_SNPN node of 3GPP TS 24.275 [36], if the UE is in the non-subscribed SNPN.

For PLMN subscription, the UE may support being configured with the indication of whether the MMTEL video is a 3GPP PS data off exempt service using the following method:

1) the MMTEL_video_exempt_non_subscribed_SNPN node of 3GPP TS 24.275 [36], if the UE is in the non-subscribed SNPN.

When the UE is only configured with the indication valid for the UE camping in the subscribed SNPN, the UE shall use this indication also when the UE is in the non-subscribed SNPN.

M.3.1.1.2 Enforcement

If the 3GPP PS data off status is "active":

a) the UE shall release according to 3GPP TS 24.229 [13] any multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, established with a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN, with media streams:

1) other than only audio;

2) other than only real-time text;

3) other than only audio and real-time text; and

4) not including video;

NOTE 1: When the 3GPP PS data off status is "active", an MMTEL session which is not MMTEL voice and which is not MMTEL video (e.g. MMTEL session with only fax) is released.

b) the UE shall not send according to 3GPP TS 24.229 [13] a SIP message related to a multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, from a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN, and with:

1) an SDP offer; or

2) an SDP answer;

with media streams:

1) other than only audio;

2) other than only real-time text;

3) other than only audio and real-time text; and

4) not including video;

NOTE 2: When the 3GPP PS data off status is "active", an MMTEL session which is not MMTEL voice and which is not MMTEL video (e.g. MMTEL session with only fax) cannot be initiated.

c) if the UE is not configured with indication that MMTEL voice is a 3GPP PS data off exempt service:

1) the UE shall release according to 3GPP TS 24.229 [13] any multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, established with a UE’s contact address containing an IP address associated with an 5GS QoS flow using NG-RAN, with only audio, only real-time text or only audio and real-time text; and

2) the UE shall not send according to 3GPP TS 24.229 [13] a SIP message related to a multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, from a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN and with:

A) an SDP offer; or

B) an SDP answer;

with only audio, only real-time text or only audio and real-time text;

NOTE 3: If the UE doesn’t send an intitial SIP INVITE due to conditions as described in bullet c.2, the UE can attempt a request for a service equivalent to MMTel voice via the CS domain – if supported and available – and, otherwise, the UE can attempt the service according to 3GPP TS 24.229 [13] and as described in clause 5.2 via non-3GPP access.

d) if the UE is not configured with indication that MMTEL video is a 3GPP PS data off exempt service:

1) the UE shall release according to 3GPP TS 24.229 [13] any multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, established with a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN, and with video;

2) the UE shall not send according to 3GPP TS 24.229 [13] a SIP message related to a multimedia telephony communication session as described in clause 5.2, which is not an IMS emergency call, from a UE’s contact address containing an IP address associated with a 5GS QoS flow using NG-RAN and with:

A) an SDP offer; or

B) an SDP answer;

with video; and

e) if the UE is not configured with indication that MMTEL voice is a 3GPP PS data off exempt service and the UE is not configured with indication that MMTEL video is a 3GPP PS data off exempt service:

1) the UE shall de-register the binding of a UE’s contact address containing an IP address associated with an 5GS QoS flow using NG-RAN from IM CN subsystem according to 3GPP TS 24.229 [13];

2) the UE shall re-register the binding of a UE’s contact address containing an IP address associated with an 5GS QoS flow using NG-RAN with IM CN subsystem with a Contact header field without the g.3gpp.icsi-ref media feature tag; or

3) the UE shall re-register the binding of a UE’s contact address containing an IP address associated with an 5GS QoS flow with IM CN subsystem with a Contact header field with the g.3gpp.icsi-ref media feature tag not including the urn:urn-7:3gpp-service.ims.icsi.mmtel ICSI according to 3GPP TS 24.229 [13].

NOTE 4: Which of the bullets 1), 2), and 3) the UE performs is influenced by other 3GPP PS data off exempt services.

M.3.1.2 Establishing an MMTEL session

If the UE is establishing an MMTEL session offering audio and if the IP-CAN of 5GS indicated that interworking without N26 is supported as specified in 3GPP TS 24.501 [42], the UE should transmit the SIP INVITE request using TCP as transport protocol.

NOTE: The use of TCP is to ensure the reception of transmitted SIP messages in case fallback to EPS for voice is used and the IP-CAN of 5GS supports interworking without N26.

M.3.2 Procedures at the multimedia telephony application server

M.3.2.1 3GPP PS data off

The requirements in clause J.3.2.1 apply.

Additionally, the following requirements apply.

When serving a UE in an SNPN using an entry of "list of subscriber data", a multimedia telephony application server supporting the 3GPP PS data off can be configured with:

1) up to two indications of whether the MMTEL voice is a 3GPP PS data off exempt service, one indication is valid for the UE camping in the subscribed SNPN, and the other indication is valid for any non-subscribed SNPN the UE is camping in using the subscribed SNPN’s credentials; and

2) up to two indications of whether the MMTEL video is a 3GPP PS data off exempt service, one indication is valid for the UE camping in the subscribed SNPN, and the other indication is valid for any non-subscribed SNPN the UE is camping in using the subscribed SNPN’s credentials.

When the multimedia telephony application server is only configured with the indication valid for the UE camping in the subscribed SNPN, the multimedia telephony application server shall use this indication also when the UE is in the non-subscribed SNPN.

When serving a UE in an SNPN using PLMN subscription, a multimedia telephony application server supporting the 3GPP PS data off can be configured with:

1) an indication of whether the MMTEL voice is a 3GPP PS data off exempt service, valid for any non-subscribed SNPN the UE is camping in using the PLMN subscription; and

2) an indication of whether the MMTEL video is a 3GPP PS data off exempt service, valid for any non-subscribed SNPN the UE is camping in using the PLMN subscription.
