7.4 Messaging p. 219

7.4.1 Introduction p. 219

Stage 3 intercept capabilities for SMS at an SMSF are defined in clause 6.2.5. Details on how to remove unauthorised content from SMS messages are defined in clause 7.4.5.2.

Stage 3 for MMS interception follows in clause 7.4.3.

Stage 3 intercept capabilities for RCS are defined in clause 7.13. Details on how to remove unauthorised content from encapsulated RCS messages are defined in clause 7.13.5.

7.4.2 LI at the MMS Proxy-Relay p. 219

7.4.2.1 Provisioning over LI_X1 p. 219

The IRI-POI present in the MMS Proxy-Relay is provisioned over LI_X1 by the LIPF using the X1 protocol as described in clause 5.2.2.

The POI in the MMS Proxy-Relay shall support the following target identifier formats in the ETSI TS 103 221-1 [7] messages:

E164Number.
EmailAddress.
GPSIMSISDN.
IMPI.
IMPU.
IMSI.
SUPIIMSI.
NAI.
SUPINAI.

7.4.2.2 Generation of xIRI over LI_X2 p. 219

The IRI-POI present in the MMS Proxy-Relay shall send xIRI over LI_X2 for the events listed in clause 7.5.2.3 of TS 33.127, which is further expanded in the present document in clause 7.4.2.4 below.

7.4.2.3 Generation of xCC over LI_X3 p. 219

The CC-POI present in the MMS Proxy-Relay shall send xCC over LI_X3 for any MMS event where CC is available and authorized for reporting for the events listed in clause 7.5.2.3 of TS 33.127.

The xCC payload shall consist of the MMS contents given as a MIME encoded document (RFC 2045) according to OMA-TS-MMS_ENC [39]. The payload format shall be set to "MIME document" (value 15).

7.4.2.4 MMS Record Generation Cases p. 220

The triggers for MMS record generation are detailed in each of clauses 7.4.3.1 through 7.4.3.20. All triggers are defined by the detection of messages at the local MMS Proxy-Relay. They belong to one of two following high-level categories:

at the local MMS Proxy-Relay, the sending or arrival of a message, either to or from the local target UE, using OMA-TS-MMS_ENC [39] definitions, or
at the local MMS Proxy-Relay, the sending or arrival of a message to or from a non-local MMS Proxy-Relay, pertaining to messages either to or from a non-local target UE served by that non-local MMS Proxy-Relay, using the inter-proxy MM4 reference point, clause 8.4 of TS 23.140 definitions.

The present document assumes that the intercepted MMS complies with version 1.3 of OMA-TS-MMS_ENC [39]. If the intercepted messages do not comply fully, or the version is other than 1.3, parameters are required to be provided only if available.

In the following tables, the acronym Multimedia Message (MM) refers to a message in particular, while Multimedia Message Service (MMS) refers to the service in general.

7.4.3 MMS Records p. 220

7.4.3.7 MMSDeliveryAck p. 228

The IRI-POI in the MMS Proxy-Relay shall generate an xIRI containing an MMSDeliveryAck record when:

the MMS Proxy-Relay receives an m-acknowledge-ind (as defined in OMA-TS-MMS_ENC [39] clause 6.4) from the MMS client in the target UE (for deferred retrieval), or
the MMS Proxy-Relay receives an m-notifyresp-ind (as defined in OMA-TS-MMS_ENC [39] clause 6.4) from the MMS client in the target UE (for immediate retrieval).

Table 7.4.3-7 contains parameters generated by the IRI-POI, along with parameters derived from the m-acknowledge-ind message (from the local target UE to the MMS Proxy-Relay), and the m-notifyresp-ind message (from the local target UE to the MMS Proxy-Relay).

Table 7.4.3-7: Payload for MMSDeliveryAck

Field Name	Description	M/C/O

version	The version of MM, to include major and minor version.	M
reportAllowed	Indicates whether the target allows sending of a delivery report. Encoded as "Yes" = True, "No" = False. Include if received by the MMS Proxy-Relay.	C
