and the available base URL to the Application Function. The 5GMSd Aware Application uses this route as M8 interface. The second route service-access-
information.js provides the corresponding ServiceAccessInformation to the data that is returned via M8.

▪ Aiming to support both delivery boost and
throughput estimation (bit rate recomm.).
▪ Developed new service consumer libraries for
communicating with the Binding Support Function
(BSF) and Policy & Charging Function (PCF).
▪ Integration into 5GMS AF underway:
▪ (No M1 provisioning: static configuration only ☺.)
▪ Additional Service Access Information at M5 for use
by the Media Session Handler.
▪ Implement M5 Network Assistance API.
▪ (Uplift of 5GMS AF to recently published TS 26.512
V17.5.0 already complete.)
▪ Additional development of the Media Session
Handler needed to invoke M5 APIs.

▪ Reuse service consumer libraries for
communicating with the BSF and PCF.
▪ Development work in the 5GMS AF:
▪ Implement M1 Policy Templates API.
▪ Additional Service Access Information at M5 to
support the Media Session Handler.
▪ Implement M5 Dynamic Policies API.
▪ Corresponding changes to the Media Session
Handler needed to invoke these at M5.

5GMS: QoE Metrics Collection & Reporting
▪ Metrics Measurement and Logging Client:
▪ Performs the measurement and logging of QoE
metrics in accordance with the Metrics Reporting
Configuration part of provisioning data, supplied by
the 5GMSd Application Provider to the 5GMSd AF,
and forwarded by the 5GMSd AF to the Media Player
via the Media Session Handler.
▪ Initial implementation of QoS metrics and
consumption collection and reporting
▪ Aim to support multiple metric schemes. In
particular:
▪ For downlink media streaming, TS 26.247 clauses
10.6.1 and 10.6.2 specify the required MIME content
type and metrics report format for the 3GPP
urn:3GPP:ns:PSS:DASH:QM10 metrics reporting
scheme

5GMS: Consumption Collection & Reporting
▪ Consumption Measurement & Logging Client:
▪ Performs the measurement and logging of content
consumption-related information in accordance with
the Consumption Reporting Configuration part of
provisioning data, supplied by the 5GMSd Application
Provider to the 5GMSd AF, and forwarded by the
5GMSd AF to the Media Player via the Media Session
Handler.
▪ Initial implementation of QoS metrics and
consumption collection and reporting
▪ Aim to support multiple metric schemes. In
particular:
▪ For downlink media streaming, TS 26.247 clauses
10.6.1 and 10.6.2 specify the required MIME content
type and metrics report format for the 3GPP
urn:3GPP:ns:PSS:DASH:QM10 metrics reporting

5GC Service Consumers (rt-5gc-service-consumers/releases)
▪ Release v1.0.0 - 5GC Service Consumers
▪ This is the first release of the 5G Core Service Consumer libraries and tools. These are based upon the Open5GS 5G Core and can be used as an independent set
of tools for testing or controlling 5G Core APIs or as libraries for adding API handling into your own Open5GS based AF implementations.

5GC: Service consumer libraries & test app
▪ The 5GMS AF needs to communicate with
the 5G Core in order to manipulate network
Quality of Service (QoS) for ongoing media
streaming sessions.
▪ Solution: reusable service consumer
libraries to invoke service operations on:
▪ Binding Support Function (BSF).
▪ Policy & Charging Function (PCF).
▪ Could also be exploited by future functions
(MBSF, MBSTF, etc.)
▪ Also developing a command line PCF test
application.
▪ To test libraries against another 5G Core.

▪ Not implemented: EXT_NOP/EXT_TIME, and optionally EXT_AUTH if used; Congestion; FEC (RAPTORQ as in RFC
6330)
▪ What it implements at the client side:
▪ 3 flavours: generic (RFC), ATSC3, ATSC3 Korean, DVB MABR - updates https://www.ietf.org/rfc/rfc9223.html
▪ ROUTE over multicast IP (UDP);
▪ Skip repeated files;
▪ Low latency;
▪ Partially implemented: File repair simple option:
▪ MPEG-2 TS: all lost ranges are adjusted to 188-bytes boundaries, and transformed into NULL TS packets.
▪ ISOBMFF: all top-level boxes scanned, incomplete boxes are transformed in free boxes, except mdat.
▪ Not implemented: Reorder (with timeout); Choose service ID to bootstrap on for ATSC 3.0 mode; FLUTE (as
documented in in RFC 3926 and TS 26.346); Congestion; FEC (RAPTORQ as in RFC 6330)

▪ Seamless switching between broadcast and OTT/unicast content delivery
▪ Enables flexible usage of bandwidth
▪ Broadcast on demand: services can be dynamically provisioned when the demand is there, otherwise
viewers are on OTT / using CDN download
▪ Off-peak times are freed for e.g. content prepositioning / data services
▪ Any mix is possible, e.g.
▪ 24/7 radio channels with robust coding and SCS 2.5kHz for high mobility
▪ 4 TV channels at 1080p / 3 Mbps during the day, but only one at UHD / 12 Mbps for a sports game in
the evening
▪ Mobility scenarios between MBSFN areas: can carry same MBMS service
