ETSI ETSI TS 129 154 V15.1.0 (2018-06)63GPP TS 29.154 version 15.1.0 Release 151 Scope This document defines the protocol for Nt reference point. Th

29、e Nt reference point includes Nt application and Nta application. The functional requirements and the stage 2 specifications of the Nt application are contained in 3GPP TS 23.203 2. The Nt application of Nt reference point lies between Service Capability Exposure Function (SCEF) and Policy and Charg

30、ing Rules Function (PCRF), it supports the negotiation of background data transfer policy and is documented in the main body of this document. The functional requirements and the stage 2 specifications of the Nta application are contained in subclause 5.6.4.1a of 3GPP TS 23.682 x5. The Nta applicati

31、on of Nt reference point lies between SCEF and PCRF, it supports the event monitoring configuration for a group of UEs and the corresponding event reporting. The Nta application is documented in Annex A. NOTE: Nta is a stage 3 name of Diameter Application due to extensibility rule mentioned in IETF

47、ontact the H-PCRF. 4.3 Functional elements 4.3.1 PCRF The PCRF is a functional element that encompasses policy control decision and flow based charging control functionalities. The PCRF uses the information received from SCEF and other available information to determine one or more transfer policies

48、 for background data to the application service provider. The PCRF provides the selected transfer policies with a reference ID to the SPR for storage. 4.3.2 SCEF The SCEF is a functional element which provides a means to securely expose the services and capabilities provided by 3GPP network interfac

49、es. The SCEF is triggered by an SCS/AS which requests for the negotiation with the PCRF for providing necessary policy to transfer background data. 4.4 Procedures over the Nt reference point 4.4.1 Negotiation for future background data transfer Based on the SCS/AS request, the SCEF shall send the Background-Data-Transfer-Request (BTR) command to the PCRF including the Transfer-Request-Type AVP with the value TRANSFER_POLICY_REQUEST(0), it shall also include the ASP identifier within the Application-Service-Provid
