Our client is one of the cloud-native pioneers in the telecom and network software space. The
company is the leading supplier of mobile, fixed and unified communications solutions for
service providers, equipment manufacturers and large enterprises. As part of a wider 5G / IoT
implementation, our client partnered with one of the largest service providers in Europe to
trial Wireless Wireline Convergence (WWC) architecture. The aim of the WWC project was to create
and test a common-core infrastructure, supporting both fixed and wireless broadband access from
a single technology stack.
The client engaged Adaptix Solutions to develop the 5G Access Gateway Function (AGF) solution component that provides subscriber authentication, authorization and accounting (AAA) services, plus hierarchical traffic shaping and policing for fixed network and 5G residential gateways. This enabled the use of common credentials, authentication and a unified approach to applying network policy.
Adaptix Solutions assembled a team of highly skilled specialists with deep 5G domain expertise
to deliver
this complex R&D project. Working closely with in-house decision makers, our experienced
team delivered an outstanding solution to the client’s AGF challenge.
We built the component from scratch as a true cloud-native solution, using microservices
methodologies and an entirely containerized deployment. It’s fully integrated with the core 5G
architecture, including N1 interfacing to the access and mobility management function (AMF), and
N3 interfacing to the user plane function (UPF).
Our expert team covered the whole development cycle, from project planning and solution
architecture, through development and testing to deployment and validation. We created the
required cloud infrastructure and CI/CD pipelines, as well as cloud-based simulations for
solution testing. In addition, Adaptix Solutions assisted the remote, live deployment of the
solution to
our client’s service-provider-partner’s UK lab, using Kubernetes and Helm.
A third-generation partnership project (3GPP) UPF in a 5G core (5GC) facilitates the AGF. Current wireline broadband networks regard policy and subscriber databases as individual components. With a 5G service-based architecture (SBA) aspects such as the policy control function (PCF) and authentication server function (AUSF) can be aligned with mobile, fixed wireless and wireline access networks. This enables common support infrastructures (e.g., the IP multimedia subsystem [IMS]) for the delivery of rich multimedia.
Together with the client, we achieved a successful trial for the world’s first implementation of
the 5G Wireless Wireline Convergence AGF standard. This included the demonstration of a seamless
integration of fixed and 5G core services that helped simplify service provider offerings.
Another important achievement was a reduction in the overall complexity of subscriber and
service management, and the promotion of always-on services through converged connectivity.
In addition, and bearing in mind the various types of access, this method ensures that
standardized services and service level agreements (SLAs) can be used for all subscribers, as
well as for individuals using other technologies to connect.
Employing an accepted core infrastructure that supports both fixed and wireless connection adds
value for most operators; companies eagerly benefitting from the resources of these formerly
diverse networks. Also, the 5G new radio (5GNR), fixed wireless access (FWA) will progressively
align with, or perhaps take over from copper for the last mile.
Implementing fixed mobile core convergence significantly lessens the constituent parts and technologies needed for broadband support, cutting both CAPEX and OPEX while streamlining supply and management.
