Broadband Forum published three new standards including 5G Wireless Wireline Convergence Architecture (TR-470), Access Gateway Function (AGF) Functional Requirements (TR-456) and Device Data Model (TR-181). Together, these documents provide functions and interfaces for Fixed Mobile Convergence (FMC), the AGF, and customer premises equipment (CPE) such as 5G-enabled routers.
Highlights:
- TR-470 – produced in conjunction with 3GPP – describes the 5G FMC architecture, providing a high-level guide for network architects and planners and enabling fixed and mobile functions to coexist over a shared infrastructure. This will facilitate multi-access connectivity and give consumers a seamless, access-independent service experience.
- TR-456 describes the functional requirements of the access gateway function. The AGF resides between fixed access networks and the 5G core network to support 5G and wireline Residential Gateways, creating a truly converged deployment. Alongside this, Broadband Forum’s Device: 2 data model (TR-181 Issue 2 Amendment 14), which is used by User Services Platform (USP), has been extended to address 5G Residential Gateways. The Device: 2 data model applies to all types of TR-069 or USP-enabled devices, including end devices, Residential Gateways, and other network infrastructure devices.
- TR-124 – the Functional Requirements for Broadband Residential Gateway Devices specification is expected to be finalized in Q4 2020. Moving from the network into the home, TR-124 has been extended to add requirements related to the 5G Residential Gateway extending the 5G control plane to the premises to open up new service opportunities with real time fulfillment.
“Operators are keen to harness and deploy fifth generation technology to exploit new opportunities to enhance existing revenue streams and secure new ones by launching new services and applications,” said Broadband Forum CEO Robin Mersh. “Spanning the full scope of the network, including CPE, these specifications take a holistic approach to network management and operation and will greatly accelerate 5G deployments, ensuring operator confidence through an open ecosystem.”
