This reference point is used between the MTC-IWF and the Services Capability Server (SCS) to invoke specific functionalities in the PLMN such as device triggering. The details for this reference point are described in TS 23.682 and TS 29.368. This interface is a PLMN internal interface if the SCS is controlled by the operator. Signalling on this interface uses Diameter Tsp Application as specified in TS 29.368.

This reference point is used between the MTC-IWF and the HSS/HLR to authorize a certain SCS to request a specific service (e.g. device triggering), and to retrieve subscription information and routing information (i.e. serving SGSN/MME/MSC identities) from the HSS/HLR. The details for this reference point are described in TS 23.682 and TS 29.336. Signalling on this interface uses Diameter S6m Application as specified in TS 29.336.

This reference point is used between the MTC-AAA and the HSS/HLR to translate an IMSI to external identifier(s) of the user. The details for this reference point are described in TS 23.682 and TS 29.336. Signalling on this interface uses Diameter S6n Application as specified in TS 29.336.

This reference point is used between the MTC-IWF and the SMS-SC to transfer device trigger to the SMS-SC inside the HPLMN. The details for this reference point are described in TS 23.682 and TS 29.337. Signalling on this interface uses Diameter T4 Application as specified in TS 29.337.

The S6t reference point is defined between the SCEF and the HSS. It provides general access to the capabilities and data of the HSS from the SCEF, including configuration and reporting of specific monitoring events. The details for this reference point are described in TS 23.682.

The T6a reference point is defined between the SCEF and the MME. It provides general access to the capabilities of the MME from the SCEF, including configuration and reporting of specific monitoring events. The details for this reference point are described in TS 23.682.

The T6b reference point is defined between the SCEF and the SGSN. It provides general access to the capabilities of the SGSN from the SCEF, including configuration and reporting of specific monitoring events. The details for this reference point are described in TS 23.682.

The Ns reference point is defined between the SCEF and the RCAF. It allows the SCEF to request and consequently be notified of the network status. The details for this reference point are described in TS 23.682.

This reference point allows for negotiation about the recommended time window(s) and the related conditions for future background data transfer between the Policy and Charging Rules Function (PCRF) and the Service Capability Exposure Function (SCEF). For more information see TS 23.203.

This reference point enables the Service Capability Exposure Function (SCEF) to manage Packet Flow Descriptions (PFDs) in the Packet Flow Description Function (PFDF) according to the instructions received from the SCS/AS. For more information see TS 23.682.

This reference point is used to exchange signalling and application data between BM-SC and GCS AS. This includes start, stop, and modification of MBMS broadcast bearer service. The details for this reference point are described in TS 23.468.

This reference point is used to exchange signalling and application data between GCS AS and UE. The details for this reference point are described in TS 23.468.

This reference point is used to define application level signalling requirements. This reference point is not specified in this release of the specification. The details for this reference point are described in TS 23.303.

This reference point is used to define the interaction between ProSe Application Server and ProSe functionality provided by the 3GPP EPS via ProSe Function (e.g. name translation) for EPC-level ProSe discovery. The details for this reference point are described in TS 23.303.

This reference point relies on EPC user plane for transport (i.e. an "over IP" reference point). It is used to authorise ProSe Direct Discovery and EPC-level ProSe Discovery requests, and perform allocation of ProSe Application Codes corresponding to ProSe Application Identities used for ProSe Direct Discovery. It is used to define the authorisation policy per PLMN for ProSe Direct Discovery (for Public Safety and non -Public Safety) and communication (for Public Safety only) between UE and ProSe Function. The details for this reference point are described in TS 23.303.

The reference point is used to provide subscription information in order to authorise access for ProSe Direct Discovery and ProSe Direct Communication on a per PLMN basis. It is also used by the ProSe Function (i.e. EPC-level ProSe Discovery Function) for retrieval of EPC-level ProSe Discovery related subscriber data. The details for this reference point are described in TS 23.303.

The reference point is used by the ProSe Function (i.e. EPC-level ProSe Discovery Function) (in the role of LCS client to query the SLP defined in OMA AD SUPL [80]. The details for this reference point are described in TS 23.303.

This reference point is between ProSe-enabled UEs used for control and user plane for ProSe Direct Discovery, ProSe Direct Communication and ProSe UE-to-Network Relay. The details for this reference point are described in TS 23.303.

This reference point is between ProSe Functions in different PLMNs (EPC-level ProSe Discovery) or between the ProSe Function in the HPLMN and the ProSe Function in a Local PLMN (ProSe Direct Discovery). With ProSe Direct Discovery this reference point is used for HPLMN control of ProSe service authorization. It is also used to authorise ProSe Direct Discovery requests, retrieve the Discovery Filter(s) corresponding ProSe Application ID name(s) and translate the ProSe Application Code to the ProSe Application ID Name. The details for this reference point are described in TS 23.303.

This reference point is between the ProSe Function in the HPLMN and the ProSe Function in the VPLMN. It is used for HPLMN control of ProSe service authorization. It is also used to authorise ProSe Direct Discovery requests, retrieve the Discovery Filter(s) corresponding ProSe Application ID name(s) and translate the ProSe Application Code to the ProSe Application ID Name. The details for this reference point are described in TS 23.303.

The Np Reference Point enables transport of RAN User Plane Congestion Information sent from the RCAF to the PCRF. The Np Reference Point is specified in TS 23.203.

The Nq reference point enables the RCAF to retrieve the list of UEs (identified by the IMSIs) served by an eNodeB or E-UTRAN cell and the list of APNs of the active PDN connections of each IMSI. The Nq reference point is specified in TS 23.401.

The Nq' reference point enables the RCAF to retrieve the list of APNs of the active PDN connections of a given UE (identified by the IMSI). The Nq' reference point is specified in TS 23.060.
