We are happy to announce the first release of 5G Multicast Broadcast Services (MBS) as part of the 5G-MAG Reference Tools. This release provides reference implementations of an MB-UPF, MB-SMF as extensions of the UPF and SMF of the Open5GS project. In addition it provides an initial implementation of AMF, gNB and UE with MBS. A simple AF/AS allows testing the setup. A tutorial is provided here: Initial MBS support in the 5GC | 5G-MAG - Reference Tools This initial functionalities of MBS support in the 5G Core, RAN and UE are complemented by Docker images and Docker Compose deployments to test the whole setup. This is a contribution from Borja Iñesta Hernández  and  Jaime Sánchez Roldán , from Universitat Politècnica de València (UPV)  to the 5G-MAG Reference Tools.

We have just released version 1.0.0 of the 5G-MAG Reference Tools - 5G Core 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. The 5G Core presents several Network Functions, each of which has its own set of service interfaces. This is a collection of reusable service consumer libraries designed to talk to the 5G Core Network Functions using some of these service interfaces. Currently available: libscbsf - Binding Support Function (BSF) service consumer library. The Binding Support Function (BSF) is responsible for maintaining a mapping between UE PDU Session and the PCF which is managing that PDU Session. The libscbsf library aids in discovery of the BSF in the 5G Core (by interrogating the NRF) and subsequently looking up which PCF is managing the PDU Session for a UE, identified by its IP address. This library implements the service consumer end of the following service-based APIs: Nbsf_Management libscpcf - Policy Control Function (PCF) service consumer library. The Policy Control Function (PCF) is responsible for applying charging and network policy to the PDU sessions of UEs. The Npcf_PolicyAuthorization service API is used at reference point N5 by an Application Function (AF) to request policy changes to the PDU session on behalf of the UE. This allows an Application Function to manipulate particular network QoS parameters for selected IP traffic flows within the PDU session. The libscpcf library allows an application to connect to a PCF and request an AppSessionContext which it can then use to manipulate the network routing policies for traffic passing across specific application flows within a UE's PDU Session. This library implements the service consumer end of the following service-based APIs: Npcf_PolicyAuthorization 👏 Big thank you to the contributors David Waring ( BBC ) and Daniel Silhavy ( Fraunhofer FOKUS ). 👉 The full release notes can be found here: https://github.com/5G-MAG/rt-5gc-service-consumers/releases/tag/rt-5gc-service-consumers-1.0.0 👉 More information about 5G-MAG and the 5G-MAG Reference Tools can be found on our website: developer.5g-mag.com/

Download 3GPP TR 26.805 (PDF) With Thorsten Lohmar (Ericsson) as rapporteur, 3GPP Technical Report 26.805 comprises a variety of relevant media production use cases, reference media production architectures and workflow descriptions to identify standardization needs and potential standards gaps when using 5G Systems for media production including Non-Public Networks (NPN) both Standalone NPN and Public-Network-Integrated NPN. Aspects such 5G System features, relevant protocols used in media production, codecs and service layers for 5G System usage, among others, are addressed in the document. Learn more about NPNs for Media Production: https://www.5g-mag.com/explainers Aspects such as relevant media production use cases, reference media production architectures, relevant QoS requirements for media production workflows, 5G System features, protocols, codecs and service layers for 5G System usage, among others, are addressed in the document. The document also contains guidelines for media producers and device manufacturers. In particular, the following are highlighted: Avoid multiplexing of different media components (e.g. MPEG 2 Transport Stream). However, when MPEG-2 Transport Stream is used, then the following suggestions should be considered: Allow extra jitter buffer for PCR timeline Do not insert null packets Encapsulate MPEG-2 Transport Stream in an RTP session according to IETF RFC 2250 Use GBR QoS flows to carry constant bit rate streams Use dynamic bit rate adaptation to avoid packet loss Provision network QoS end-to-end Use client-initiated control protocols to avoid problems with firewalls and NAT Use unicast IP data flows in preference to multicast IP Use precise time synchronisation Use packed-based transmission for audio streams with a single parameter set 3GPP also recommends 5G-MAG to identify a follow-up on these guidelines to support media production device manufactures and media producers to leverage different 3GPP features for their purposes. Beyond the individual contributions by 3GPP members, 5G-MAG organized several workshops to reach out to various media producers and device manufactures with respect to 5G network usage. https://www.5g-mag.com/post/5g-mag-workshop-media-production-over-5g-npn https://www.5g-mag.com/post/5g-mag-workshop-media-production-over-5g-npn-deep-dive-into-protocols A site on trials is also maintained by the association: https://www.5g-mag.com/trials

Download (PDF) https://drive.google.com/file/d/1OJkHzjXeI9SrlXE98D7kxdD7b_m6dxXS/view?usp=share_link 3GPP Release 17 brings Multicast–Broadcast Services (MBS) to the 5G System, based on 5G Core and New Radio. MBS allows the network to select the most suitable among point-to-multipoint (PTM) or point-to-point (PTP) delivery based on requirements set by either service providers or network operators and/or taking into account concurrent user demand. Multicast Services A Multicast Service uses PTM and/or PTP delivery methods to transport traffic from a single source to User Equipment (UE) terminals within a multicast service area that have subscribed to the service. Multicast traffic is efficiently and reliably transported over the 5G core network to compatible base stations using the shared traffic delivery method. The individual traffic delivery method can serve multicast traffic to legacy base stations that do not support MBS. MBS-enabled base stations autonomously decide whether to use PTM or PTP delivery methods at the radio access network based on the number of concurrent subscriptions and the quality of the radio channel. To receive Multicast Services, UEs must first subscribe to a multicast group. Base stations 1 and 2 use the PTM delivery method to serve subscribed UEs within their reception footprints. Base station 2 additionally uses the PTP delivery method to serve UEs that require more robust delivery. Base station 3 (not supporting MBS) can deliver multicast packets via a conventional unicast PDU session unique to each subscribed UE. Broadcast Services A Broadcast Service uses only the PTM delivery method to transport traffic from a single source to multiple UEs within a broadcast service area. Any UE within the broadcast service area that has registered with the network can receive Broadcast Services. A single copy of the MBS traffic is efficiently transported over the 5G core network to each MBS-compatible base station in the service area using the shared traffic delivery method. A Broadcast Service is available to compatible UEs within the broadcast service area, always using the PTM delivery method. What kinds of service could be offered with 5G MBS? MBS supports the delivery of both operator and third-party media content. In particular, MBS User Services allow popular online television and radio services (e.g. live sport or national events) to be delivered efficiently to compatible equipment such as smartphones, smart TVs or car infotainment systems. Broadcast is suitable for localized services at the granularity of individual cells (e.g. services in venues, stadiums, exhibition centres). Multicast allows the efficient and scalable delivery of popular services while ensuring a similar quality of service (QoS) and reliability to that of unicast distribution. Quality of experience is independent of audience size and network congestion is mitigated. Multicast allows a group of UEs to receive services according to QoS requirements and/or prevailing channel conditions. Additional characteristics To minimize implementation impact and complexity, MBS reuses the existing (3GPP Release 15/16) radio-layer design for physical channels, reference signals, and sub-carrier spacings and cyclic prefixes. How is the coverage area of a service determined? For both Multicast and Broadcast Services, individual cells may be added to or removed from the service area. The Multicast Service is transmitted only in cells within the multicast service area in which there are UEs that have joined an MBS session. Cells within the broadcast service area transmit the Broadcast Service regardless of whether the service is requested or not. For multicast, link adaptation selects the most appropriate modulation and coding scheme (MCS). Beamforming is optimized for the UEs in the multicast group. For broadcast, each service is pre-assigned an MCS, as there is no channel-state information feedback from UEs. Single frequency network (SFN) operation is possible across sectors of the same base station for multicast. For broadcast, SFNs can be implemented across base stations that are sufficiently close to each other, transparent to UEs. How is reliability of reception managed? For multicast, provision of UE feedback, support of retransmissions using PTP or PTM, link adaptation, and beamforming, among other mechanisms, ensure reliability. For broadcast, services are delivered with no guarantee of reception, however data repetition (slot-level) is possible for improved performance. How are mobility and service continuity managed? For multicast, service continuity across cells is supported by handover between the base stations a UE traverses. For broadcast, neighbour-cell information and cell-reselection mechanisms are available but may not ensure lossless handover. Can MBS services be transmitted together with other types of traffic on the 5G network? Mixed radio carriers can deliver multicast and/or broadcast services alongside other unicast data on the same cell. Learn more... A paper from Qualcomm and a blog post from Ericsson provide more details about MBS. For a detailed list of 3GPP specifications please refer to: 5g-mag.com/standards

Download ETSI TR 103 972 v1.1.1 (PDF) A new Technical Report from ETSI, arising out of a collaboration between the DVB Project and 5G-MAG , provides guidelines on the deployment of DVB-I services over 5G Systems including the 5G Media Streaming Architecture and LTE-based 5G Broadcast. Published just ahead of the summer break in Europe, TR 103 972 v1.1.1 shows how relevant components from both the 5G and DVB ecosystems can be smartly combined to address several media service scenarios. JOINT TASK FORCE SUCCESSFULLY CONCLUDED The Joint Task Force between DVB and 5G-MAG kicked off early in 2022 with the mission to map the Commercial Requirements for DVB-I service support over 5G networks and systems ( DVB BlueBook C100 ) into a set of deployment guidelines. The resulting ETSI Technical Report includes high-level summaries of technologies from DVB (DVB-I, codecs, and delivery formats such as DVB-DASH, DVB-MABR and DVB Native IP), from 3GPP (5G System, 5G Media Streaming, eMBMS and enhanced TV), and of the LTE-based 5G Broadcast System defined in ETSI JTC Broadcast. The report also sets out the 5G-MAG Reference Tools architecture and client components related to DVB-I over 5G. The detailed service scenarios covered in the report are: Standalone DVB-I service using 5G Broadcast DVB-I service using 5G Media Streaming DVB-I service offering available simultaneously over broadcast and unicast. A DVB-I over 5G reference architecture is proposed to support all service scenarios and requirements. Each scenario includes workflows with guidance on relevant specifications. Gaps in existing specifications are identified and documented as recommended changes to the relevant specifications under the control of DVB, 3GPP or ETSI. IBC PAPER The Joint Task Force was led by Dolby’s Frédéric Gabin (for the DVB Project) and Qualcomm’s Thomas Stockhammer (for 5G-MAG). Richard Bradbury of BBC was also a major contributor to the work. A technical paper on the work by the three will be presented during the IBC2023 conference during a session on 5G technology convergence with broadcast . More than 65 people from among the memberships of DVB and 5G-MAG joined the Joint Task Force to follow and contribute to the work, representing more than 40 companies in total. With the ETSI report now published, the task force will be wound down and the required follow-up work will continue in the respective organizations. 5G-MAG REFERENCE TOOLS FOR DVB-I OVER 5G UNDERWAY The 5G-MAG REFERENCE TOOLS; the open-source software development programme established by 5G-MAG and open to the community. is already developing the 5G Systems for multimedia applications, including the 5G Media Streaming Architecture and LTE-based 5G Broadcast. Its extension to support DVB-I services is on the roadmap for the comming months. Contributions are welcome and developers can contact reference-tools@5g-mag.com or explore the Developer Space for more information.

We have just released version 1.2.0 of the 5G-MAG Reference Tools - 5G Media Streaming Application Server. This change to the behaviour of the 5GMS Application Server allows it to handle 3XX HTTP redirections received from configured media origins and translate these into local redirects to be passed to the Media Stream Handler on the UE. This maintains the connection between the UE and the 5GMS Application Server instead of the UE being redirected to an external server. 👏 Big thank you to the contributors David Waring ( BBC ) , Dev Audsin ( BBC ), Richard Bradbury ( BBC ), Jordi Joan Giménez ( 5G-MAG (5G MEDIA ACTION GROUP) and Daniel Silhavy ( Fraunhofer FOKUS ). 👉 The full release notes can be found here: https://lnkd.in/ejskZd5A 👉 More information about 5G-MAG and the 5G-MAG Reference Tools can be found on our website: developer.5g-mag.com/
