Open RAN

 

Accelerating Network Transformation through Disaggregation

Open RAN represents a significant shift in the Radio Access Network (RAN) architecture. While traditional RAN systems use proprietary, hardware-centric technologies, Open RAN introduces an open, intelligent, and flexible approach to network construction. The concept is anchored on the disaggregation of hardware and software. It leverages standard processors and open interfaces to develop a robust and versatile network architecture. The concept of Open RAN (often referred to as O-RAN) is rooted in the standards set by the O-RAN Alliance. Established in 2018 by a consortium of service providers, the O-RAN Alliance aims to specify requirements and harness the potential benefits of open RAN architecture. O-RAN is characterized by four key functional blocks: Virtualized Distributed Unit (vDU) supporting Remote Radio Units (RRUs) Multi-connections, radio access technology (RAT) agnostic Virtualized Centralized Unit (vCU) RAN Intelligent Controller (RIC) Centralized management and orchestration The above components work synergistically to form a flexible, intelligent, and cost-effective RAN, which can dynamically adapt to varying network demands.

From Legacy RAN to Open RAN: An Evolutionary Perspective

Traditional RAN architectures were based on the Distributed Radio Access Network (D-RAN) model. Here, Baseband Units (BBUs) and Remote Radio Heads (RRHs) were proprietary and usually co-located at the same cell site. The move towards a Centralized RAN (C-RAN) saw the creation of a “centralized BBU pool.” However, the Common Public Radio Interface (CPRI)-based fronthaul struggled to meet the capacity and performance requirements of 5G networks. Both D-RAN and C-RAN architectures come with high operating expenses (Opex), underutilization of RAN resources, and limited deployment flexibility for 5G. Cloud RAN, or C-RAN, emerged as a solution to these challenges. It built upon the centralization concept by running virtualized baseband functions on Commercial Off-The-Shelf (COTS) server hardware. This model leveraged Network Functions Virtualization (NFV) to create a more flexible and scalable architecture.

The Cloud RAN paradigm gradually evolved into Open RAN, expanding on openness and embedded intelligence principles. The openness in the architecture facilitated multi-vendor deployments, reducing vendor lock-in and promoting competition. The embedded intelligence leveraged advanced technologies like Machine Learning (ML) and Artificial Intelligence (AI) to automate operational network functions, further reducing operational costs. Overall, Open RAN represents a substantial progression in RAN architectures, offering benefits in terms of cost, flexibility, and performance. Open RAN is poised to play a pivotal role in 5G deployments and beyond by embracing open standards and intelligent functionalities.

TIP’s Role in Open RAN

TIP is there to catalyze and support the industry effort and help to resolve some of the challenges, such as by proving out various configurations for Open RAN fronthaul sub-systems or Open RAN Cloud, the role of SIs, reskill/upskill transformation within organizations, lowering the cost of hardware. And let’s not forget there’s more necessary innovation required in Open RAN, such as further disaggregation at the chipset and radio level, network performance & energy management through RIC and xAPPs/rAPPs, and orchestration and automation models in Open RAN.

TIP has done critical foundational work to help build purchaser confidence and address supply chain efficiency issues vis-a-vis its:

  • Open RAN Project Group and its sub-groups
  • It’s badging of products and solutions
  • Its marketplace processes, called “TIP Exchange”

TIP’s Open RAN Project Group and sub-groups – in cooperation with leading operators, vendors, systems integrators, and other stakeholders throughout the world – seek to harmonize requirements for Open RAN solutions that comprise radio units (“RUs”), distributed units (“DUs”), and centralized units (“CUs”), as well as the RAN Intelligent Controller (“RIC”) platforms and applications, and many other components of Open RAN solutions. Like other TIP project groups, the Open RAN Project Group emphasizes creating joint roadmaps that are built on market demand, then building and testing products at scale. TIP’s process encompasses technical roadmaps, solution blueprints that correspond to deployment scenarios as well as testing activities, and a range of resulting deliverables that document the results of the process.

Four major stages of Flow

Creation of technical roadmaps, where operator requirements, commercial priorities, and use cases are identified and translated to definitions with a feedback loop with participating vendors, ensuring that all inputs from the industry are accounted for; Testing and validation based on blueprints and test plans that ensure that components integrated as a solution can operate as a complete Open RAN system and be deployed in a live network; and Publishing the blueprints, the test plans as well as the badged products and solutions on the TIP marketplace, TIP Exchange. TIP Exchange enables participating operators to identify suitable solutions and vendors to promote their products and services based on documented results from participating in the process. Lifecycle management of the badged products and solutions.

All four stages are supported by TIP Academy, which provides industry-leading training and education programs for Open RAN. The SCOPE process gets its initial technical documentation from the TIP OpenRAN Project Group, which makes system Blueprints and Test Plans needed for the process. The participating operators have approved these deliverables to represent the targeted deployment scenarios. Actual Open RAN configurations chosen by operators will be integrated and tested as a system in a TIP-accredited System Certification Laboratory. The testing will be based on approved Test Plans, and results will be documented and provided as input for the formal TIP System Certification process. Successful Certification will enable the products and the system as a whole to be allocated TIP Badges according to the SCOPE criteria.

In 2020, TIP carried out a successful pilot of a System Release Certification process for Open RAN, proving that new releases of Open RAN would be tested 60% faster with a centrally coordinated Certification process. The learnings from this successful pilot have led to the development of the SCOPE T&E framework.

 

Global Coordination and Cost-Effectiveness

The global coordination by TIP ensures cost-effectiveness and total market impact. TIP prioritizes Open RAN configurations corresponding to deployment scenarios aligned between a large cross-section of global operators, thus saving duplication cost and time for the vendors, system integrators, and operators involved.

SCOPE will increase operators’ confidence in deploying Open RAN technology into live networks today. Operators want carrier-grade solutions and lower integration and testing overhead. For vendors and operators – SCOPE, alongside the TIP community-driven Project Groups and TIP Exchange, presents a way to meet both these challenges and increase the availability of Open RAN solutions.

FYUZ 2023: Showcasing the Momentum of Open and Disaggregated Solutions

Fyuz, TIP’s flagship conference in October 2023, continues to be the landmark event for the industry showcase & debate on Open & Disaggregated Network Solutions. We are looking forward to coming back to Madrid – at the same venue, with an improved and knockout format and a transition to a new theme of showcasing the momentum across open and disaggregated solutions in the industry. We are looking forward to hearing more from the pioneers across the industry on what has been commercially deployed, but more importantly, what still needs to be done to scale Open RAN, OpenWiFi, Open Transport and where the pockets of new innovation are opening up.

Over the past year, the industry has also seen a broader set of Governments pushing forward on their supplier diversification strategies and opportunities to develop global approaches toward scaling a diverse telecom supplier ecosystem. The TIP Open RAN community is growing stronger and driving an industry-relevant roadmap of innovation and solutions. FYUZ will continue to have Open RAN as an agenda item (along with other flagship programs such as OOPT and OpenWiFi, as well as those that some might say sit on the sidelines, including NTCS, TelCo Cloud, and Private Networks). Visit fyuz.events to learn more about it and register.

In many ways, the principles behind an open, multivendor RAN have been pioneered in the small cell environment. The small cell ecosystem has always supported new and established vendors together, and SCF has developed a range of open interfaces within the RAN, including FAPI (functional API), internal to RAN products, and Network FAPI, which defines a fronthaul connection between radio units and functional baseband units.

Small Cell Networks: A Low-Risk Environment for Open RAN

The industry is now moving towards these open and disaggregated architectures in every part of the RAN, and many organizations, including SCF and the O-RAN Alliance, are working together to address the challenges of developing and deploying a RAN that is not only multivendor but in many cases virtualized, with some or all of the baseband elements (distributed unit and centralized unit) running on cloud infrastructure. There are many lessons to be learned from the early experiences of open networking in the small cell world, including ways to simplify roll-out, management, and automation. SCF is distilling this experience into operator requirements and blueprints to help lower cost and risk for early adopters (How blueprints unlock the potential of 5G networks.) Many of the early commercial open RANs have been deployed as small cell networks, often for enterprise or private network scenarios. This is because such networks are often greenfield, are usually localized, and do not need very high complexity/cost technologies such as Massive MIMO. All these factors mean small cell networks are often a relatively low-risk environment in which to learn about Open RAN while targeting some immediate new revenues, whether the deployer is a conventional MNO or a new player such as a neutral host or private network operator.

Choices in RAN Functional Splits

There is no one solution that will fit all requirements. 3GPP has defined a large number of ways to split RAN functions between two or three units (Radio Unit RU, Distributed Unit DU, and Centralized Unit CU), and SCF’s annual survey of deployers shows there is market need for a choice of approaches. 3GPP has standardized split 2 and SCF has pioneered split 6, which places the Layer 1 network functions (the most processor-intensive) on the RU, while O-RAN Alliance is working on split 7.2x, in which some of the Layer 1 functions run in the DU. In the spirit of true and complete openness, SCF’s split 6 work (i.e. (n)FAPI work) strives to ensure that the control plane, user plane, and management plane are all fully open to support multiple hardware and software offerings in each plane.

Our survey of 113 deployers highlighted the need for both the split 6 & 7.2 options (and others such as Split 8 and Split 2). And many roll-outs will still focus on integrated small cells, which in some networks can provide the simplest and most power-efficient approach. 44% of deployers expect to support three or more splits by 2027, across their various networks (whether macro or small cell), according to our survey.

The functional split is not the only choice to be made. Whether to collocate the RU and DU, or DU and CU, is another deployment decision, as is potential integration with edge compute nodes and the type of fronthaul connection. In each case, the options chosen must relate directly to the applications and use cases that are most important to the deployer.

The SCF survey indicated that Split 6, for instance, is the preferred goal in enterprise and indoor networks, while Split 7.2x is more preferred for urban macro RANs.

Simplifying Small Cell Network Deployments

 

SCF is ensuring diversity without fragmentation

There is a huge diversity of environments, applications, deployers, and commercial models enabled by dense 5G networks. That inevitably means there must be a diversity of network architectures, but this raises the danger of fragmentation, which in turn would deprive vendors of the scale that they need to enter the market. The solution is to ensure operators or integrators can select multiple different approaches while innovating on a common platform.

SCF’s work in promoting openness and interoperability

This has been a central tenet of SCF’s work on open small cell networks. FAPI takes open interoperability right down to the components on a system-on-chip, while nFAPI implements Split 6-based fronthaul in a way that provides a wide choice of fronthaul transport technologies, including enterprise Ethernet (5G FAPI_PHY API Specification.) But this is not a simple Lego set of options – choosing and integrating them is complex and can add to the cost of deployment. The cost of integration can be particularly serious in a small cell network where TCO is often a critical consideration.

Tools and reports to assess impact and performance

SCF supports several ways to ease this burden, providing tools for assessing the impact of each architecture choice on the chosen use case, deployment blueprints, and support for plugfests and testing. SCF has published reports assessing the impact of some of the key factors that influence performance in different use cases, including fronthaul bandwidth, latency requirements, and how complex the RU and/or DU can be. (See – Options for split RAN: Flexibility within a common framework)

Introduction of SCF DARTs for quantitative evaluation

It also provides a ground-breaking tool for making quantitative evaluations of these network options. This is SCF DARTs, a calculator that enables organizations to plan, design, and budget for transport networks for open RANs. (DARTs – An analysis tool for Disaggregated RAN Transport). In this way, operators can use objective tools and data to assess the best options for their use case and implement their chosen architecture within open frameworks to allow for future-proofing and future changes.

Flexible and cost-effective reference designs

Reference designs are also essential for product developers, who have to make their own decisions about which options to prioritize and create product lines that are flexible enough to support multiple options cost-effectively. For instance, there is an emerging demand for multiband enterprise small cells that support 4G and 5G and allow existing LTE networks to be migrated to 5G vRAN over time.

Open testing and certification for successful standards

To build operator confidence, the resulting solutions must be proven to be open and interoperable without the deployer having to invest in significant custom testing. Open testing and certification is the key to many successful standards and will be crucial for Open RAN to gain scale. SCF, O-RAN Alliance, and Telecom Infra Project (TIP) have been heavily focused on supporting standard, industry-wide testing processes, including participation in plugfests. Robust certification of compliance with Open RAN standards will be a critical success factor, especially for enterprise small cell networks where deployers will be buying large quantities of cells but will typically not have in-house interoperability testing capabilities.

Stakeholder collaboration across industry alliances

Collaboration between stakeholders and between all the industry alliances focused on open networks will be important to accelerate progress and share best practices. SCF works with O-RAN Alliance, 3GPP, Open Air Interface (OAI), and many others in technical, commercial, and regulatory dimensions. These cooperations help to drive confidence and a vibrant ecosystem but also educate the whole community of potential deployers. Open systems, coupled with the emergence of open source code and shared spectrum, can enable a host of new deployers, especially in enterprise and smart city spaces where small cells are essential.

These new operators, alongside the established MNOs, can accelerate the availability of high-performance cellular connectivity for every scenario. However, they lack the long years of cellular experience of the MNOs, and so education and confidence building will be as important to the work of industry associations as specifications and certifications.

Driving Open RAN Adoption in All Domains

With a combination of all these efforts, technical and commercial proof points can be quickly established in small cells, and this knowledge will help to foster the adoption of Open RAN in all domains, regardless of use case and architecture. That, in turn, will result in significant growth in the deployment of open vRAN architectures, which will account for over half of the small cell installed base by 2028, according to SCF’s latest forecast (Figure 2), with 94% CAGR between 2021 and 2028.

In an era defined by digital transformation and seamless connectivity, we find ourselves at the forefront of a paradigm shift in telecommunications, and the importance of international cooperation on Open RAN cannot be overstated. Open RAN, which emphasizes a disaggregated and open approach to network architecture, has the potential to revolutionize global communication networks by enabling interoperability, fostering innovation, and democratizing access to advanced wireless technology. However, to harness its true potential, governments worldwide must embrace pro-Open RAN policies, unlock funding to encourage new deployments, and encourage cross-border investments.

Global Momentum Towards Open RAN

The shift to openness and interoperability in networks has gained tremendous momentum in recent years. This is in part due to government support worldwide, which has played a critical role in driving the transition to an open approach to 5G. Collaboration among governments, policymakers, industry stakeholders, and standards bodies is helping to facilitate the deployment of Open RAN and ensure seamless interoperability across networks. By continuing to foster global standardization, governments can use Open RAN to their advantage in enhancing connectivity in remote and underserved regions, narrowing the digital divide, and promoting socio-economic development worldwide.

Facilitating Open RAN Cooperation

The Open RAN Policy Coalition has been privileged to facilitate a Quadrilateral Security Dialogue track 1.5 discussion series on Open RAN, with participation from governments and association partners in Australia, India, Japan, and the U.S. Bringing together government and industry leaders to discuss advancements in Open RAN deployments and fostering innovation, we have underscored the importance of secure and trusted infrastructure for 5G and advanced wireless networks. Initiatives like this are crucial as Open RAN plays a significant role in delivering on key priorities like security and vendor diversity across the telecoms ecosystem.

Policy Roadmap for Open RAN

Policymakers across the globe have a crucial role to play in shaping the future of telecommunications, and as such, a well-structured policy roadmap is vital for supporting Open RAN deployments. By providing clear guidance and incentives, governments can facilitate more private sector investment in infrastructure and more commercial deployments. This includes measures to encourage research and development, testing, and establishing favorable regulatory frameworks that promote competition and innovation. A comprehensive policy roadmap can act as a guiding light for nations looking to embrace the Open RAN revolution.

Fostering a Robust Ecosystem for Open RAN

Fostering a robust ecosystem of Open RAN vendors and solution providers will maximize the impact of pro-Open RAN policies. Promoting research and development in this sector can lead to breakthrough innovations, further driving down costs and improving the performance of Open RAN networks. Governments can also support initiatives that promote Open RAN awareness, education, and workforce development, ensuring that a skilled workforce is available to deploy and maintain these advanced networks.

Public-Private Funding for Open RAN Initiatives

While the benefits of Open RAN are evident, significant investments are required to deploy next-generation networks on a global scale. In order to do that, governments must actively explore avenues to unlock funding for Open RAN initiatives. Public-private partnerships can be instrumental in mobilizing financial resources, with governments providing initial funding or incentives and the private sector contributing technical expertise and capital. Another strategy that has been successful in promoting commercial deployments is the earmarking of a portion of existing telecommunications budgets specifically for Open RAN projects, which also signals government commitment to the technology and attracting additional investment from private stakeholders.

Policy Strategies for Interoperable Networks

Other policy strategies that encourage network operators to make the transition to open and interoperable networks can include tax incentives, grants, and simplified regulatory procedures for infrastructure deployment. By creating a level playing field for Open RAN solutions, governments can spur competition among vendors and drive down equipment costs, benefiting consumers and businesses alike.

International Open RAN Cooperation

In the United States, foreign assistance can play a crucial role in supplementing non-U.S. programs aimed at advancing Open RAN. By granting exemptions from stringent lending requirements by the U.S. International Development Finance Corporation (DFC) and Export-Import (EXIM) Bank for advanced wireless telecommunications infrastructure projects, the U.S. can demonstrate its commitment to global connectivity. Such support can foster international cooperation, encourage cross-border investments, and solidify the U.S. as a leader in the Open RAN revolution. Modernizing the EXIM Bank is an example of how the federal government can use existing institutions to create new mechanisms and opportunities for foreign investment. The EXIM Bank can and should serve as an attractive partner for American businesses working abroad; small and smart incentives or creative partnerships through the EXIM Bank can help offset enough risk to make opportunities for overseas investments more attractive.

Conclusion: Advancing Open RAN

Open RAN holds the key to enabling secure and diverse telecoms infrastructure, supporting the advancement of 5G and advanced wireless networks, and fostering innovation and competition in the telecommunications industry. By continuing to work globally with policymakers, standards bodies, and industry stakeholders, we can incentivize deployments, unlock funding for Open RAN, and foster policies that will usher in a new era of global connectivity to bridge the digital divide, stimulate economic growth, and propel humanity towards a more connected and prosperous future.

CAMARA APIs: Introduction

The telecommunications industry is entering a new era of innovation, unlocking significant potential through the integration of customer use cases with open networks via APIs. As we navigate through the dynamic digital landscape, these integrations not only enable enhanced service capabilities but also contribute to generating new revenue streams for telecom providers. With the advent of the CAMARA APIs, we witness a seamless bridging between customers and Telecom network capabilities across various networks and countries, hence simplifying the complexity inherent in these networks.

Telco network capabilities, while partially available in 4G, have seen an impressive evolution with the advent of 5G, offering us not just the ability to extract information from the network but also enables us to configure it according to our needs. CAMARA APIs provide on-demand, secure, and controlled exposure to these capabilities, transforming operator networks into powerful service enablement platforms. This evolution opens a multitude of possibilities for improved application-to-network integration, a critical aspect for delivering enhanced and service-tailored customer experiences in the 5G era. A deep dive into the capabilities of the 5G network, like identifying the location of user equipment, monitoring the number of user equipments in a geographical region or in a network slice, adapting video resolution based on network congestion, enabling augmented reality through Quality on Demand, supporting low-energy IoT devices, and managing crises by blocking user equipments in a geographic region, shows us the vast potential of these APIs and the new horizons they open up in the telecom sector.

Tackling Telecom’s Hurdles Head-On

The CAMARA Project takes aim at several critical issues faced by developers and multinational corporations in today’s interconnected telecommunications landscape.

Ensuring Scalability through Standardization

A significant hurdle that the CAMARA Project tackles is the quest for scalable business solutions. With the rapid evolution of the digital world, customers now anticipate the same APIs to be accessible across all telecom networks and countries. This expectation presents a demand for the standardization of APIs, which is crucial to ensure scalability and aid developers in their pursuit of creating the next globally recognized product, application, or service.

Achieving Consistency in a Diverse Network Environment

In a world where multinational corporations operate across multiple markets, the CAMARA Project aims to deliver consistent API experiences. Corporations require APIs that work seamlessly, regardless of the network or country, eliminating the need to cater to the unique characteristics of each network.

Simplicity amidst Complexity

The inherent complexity of telecom networks can be a deterrent for developers. The CAMARA Project is striving to cut through this complexity and provide simple, intent-based APIs. These APIs make the process of integration less cumbersome, encouraging more developers to leverage the power of telecom networks.

Enhancing Accessibility through Open Source

In an effort to make APIs more accessible, the CAMARA Project has embraced an open-source model, choosing the Linux Foundation as its home. This approach allows API users to work directly with Communication Service Providers (CSPs) in creating the service, facilitating a more collaborative, modern, agile, faster, and transparent development process.

A Demand-driven Approach to API Development

Finally, the CAMARA Project is committed to a demand-driven approach to designing and developing APIs. By gathering demand from organizations like the GSMA Operator Platform Advisory Group (OPAG) and directly from customers, CAMARA ensures that the APIs developed meet its end users’ needs and requirements.

Defining the Boundaries: The Scope of the CAMARA Project

The CAMARA Project has a broad scope, focusing on several pivotal API development and deployment aspects. It begins with the collection of API requirements from the GSMA Operator Platform Group and other sources to ensure the APIs developed meet the current needs of the industry. Subsequently, the Project sets out to define Service APIs and Service Management APIs, laying a solid foundation for development and testing. A key part of the CAMARA Project’s scope involves creating detailed test plans, cases, and tools from an API consumer’s perspective. This step is crucial to ensure that the APIs function as intended and meet the highest standards of quality and reliability. Additionally, the Project aims to develop comprehensive, developer-friendly documentation, making the APIs easy to understand and utilize, thereby maximizing their potential impact.

As part of its deliverables, the CAMARA Project provides clearly defined and well-documented Service API and Service Management API. Optional API codes are also made available for easy adoption of APIs in telco networks. Furthermore, the Project delivers thorough test plans, cases, and tools, all packaged conveniently for deployment. All these resources, including the API definitions, test plans, and documentation, are readily accessible in the project’s GitHub repository (https://github.com/camaraproject). From a functional standpoint, the Project’s scope is restricted to telco customer-facing service and service management APIs. These APIs cater to various aspects of the telecommunications landscape, including mobile networks, fixed-line networks, edge cloud, and other related areas.

Charting the Course: The CAMARA Project’s Journey So Far

The CAMARA Project began as an initiative to de-facto standardize APIs by code, kicking off its journey at MWC22 with the support of 22 partner companies. The objective was to implement a modern, agile approach that would make the standardization process quicker and more efficient than traditional methods. The open-source nature of the project made it easily accessible to developers, with the development of the API definitions always staying in tune with customer demands.

Deutsche Telekom has labs in Berlin, Krakow,and Seattle with dedicated 5G cores from different vendors. These allow tests to make sure the APIs work in different environments. Using a defined method to onboard customers, perform tests and structured research the labs enable high valuable feedback for the APIs.

5G Future Forums – 5G MEC Acceleration Program

Abstracting Complexity: The Architecture of CAMARA APIs

The CAMARA Project champions an abstraction API architecture aimed at simplifying the complex technical landscape of telecom networks. The goal is to provide customers with intent-based APIs that eliminate the need for detailed technical know-how and allow for a more streamlined, user-friendly interaction with the network capabilities. This approach does away with the complexities often associated with terms like ‘cell ids’ or ‘slices’, which tend to vary from network to network. Instead, the APIs are designed to respond to the intent of the request while the back-end telecom infrastructure executes the necessary technical steps. For instance, a customer might request low latency for the next hour with the Quality on Demand feature.

To fulfill this request, the telecom network would then optimize various elements – device connectivity, RAN, exchange point location, fixed line optimization, application edge location, and WIFI devices. All the while, the customer sees only their initial request and the final result, thus abstracting the underlying complexity. Abstraction from Network APIs to Service APIs is a crucial part of the CAMARA project as it: Simplifies the complex telecom network, creating APIs that are easy to consume even for customers with limited telecom knowledge. Ensures compliance with data privacy and regulatory requirements. Facilitates the integration of applications with the network.

This strategic approach helps to bridge the gap between the complex world of telecom networks and the simpler, more accessible world of user-end applications.

The Open Gateway Ecosystem: CAMARA’s NaaS API Development

In the world of API development, standardization and interoperability are critical. The CAMARA Project works in collaboration with leading organizations like the GSMA, TM Forum, and the Linux Foundation to harmonize API standards through the Open Gateway Initiative. This collaborative effort resulted in a whitepaper providing a single, industry-wide solution. CAMARA abides by the “exposure” doctrine, outlining how capabilities are made available for external consumption via APIs. The project maintains repositories for various Consumer-facing API families. Service APIs’ definition, development, and validation are executed within different CAMARA Sub-Projects, while Service Management APIs are developed as specific API families within CAMARA. The CAMARA Commonalities working group delineates the API design guidelines, ensuring a uniform API language for developers. These guidelines, focused on elements like header, naming convention, error codes, etc., are designed to be developer-friendly, and all Service and Service Management APIs must comply with them.

From a functional standpoint, CAMARA’s focus is on telco APIs, covering domains like mobile networks, fixed-line networks, and edge clouds. The project primarily emphasizes the northbound interface (the interface between the telco operator and capability consumer), with east-/westbound interface APIs falling outside of CAMARA’s scope (that is covered by GSMA Open Gateway.)

The Northbound APIs are organized into the following categories:

  • Service APIs: These APIs are designed for end consumers and are integrated by developers to utilize specific telecommunications capabilities, such as checking the latency and requesting quality on demand.
  • Service Management APIs: These APIs are used by end consumers to control or gather information about the offered Service APIs in application runtime. For instance, they may be used to monitor current network performance.
  • Operate APIs: These are operational and maintenance APIs provided by telcos to channel partners to assist in service fulfillment and assurance. For example, they are used to link hyper-scalers and aggregators with telcos environments.

While Service APIs and Service Management APIs fall within CAMARA’s purview, Operate APIs do not, as they are already covered by other Standards Development Organizations (SDOs) such as the TM Forum.

From Telco Service Exposure Platforms, CAMARA APIs are exposed through Telco-owned portals and third-party marketplaces like hyperscaler and aggregator portals to the end consumers. Hyperscalers and aggregators have the possibility to create their own enriched products based on the CAMARA APIs and expose that in addition to the CAMARA APIs.

Synergizing CAMARA and GSMA Open Gateway Initiative

The GSMA Open Gateway initiative is a transformative framework of Application Programmable Interfaces (APIs) devised to offer developers and hyperscalers universal access to operator networks. This global endeavor is rooted in GSMA’s expertise and aims to support its members in exposing and monetizing telecommunications network capabilities through Open APIs and universal federation. It serves as the unifying ‘glue’ that melds cloud infrastructure-based services with terrestrial telecommunication networks. The initiative is set to fast-track the development of immersive technologies and services in various areas, including industrial systems, fintech, identity, smart mobility, gaming, Extended Reality (XR), and further Web 3.0 innovations.

In the context of the CAMARA Alliance, the GSMA Open Gateway introduces commercial topics and east-west federation to complete the ecosystem. It ensures standardized northbound business agreement templates for customers utilizing CAMARA APIs and facilitates the development of operator-to-operator interfaces, processes, and APIs to enable federation. The below architecture of this collaborative endeavor showcases the strategic alignment of CAMARA with the GSMA Open Gateway Initiative.

Forging Ahead: The Roadmap for the Future of the CAMARA Project

Looking towards the future, CAMARA is set to become the one-stop destination for all customer and developer-centric northbound APIs. Our forward-thinking strategies include:

  • Addition of more APIs and synchronization of roadmaps across Communication Service Providers (CSPs) and Hyperscalers, aiming to provide comprehensive service offerings that meet various customer needs.
  • Establishing a Technical Steering Committee (TSC) and fortifying project governance, enabling CAMARA to serve as a reliable partner for the entire industry.
  • Consistency in API lifecycle management and global documentation of API versioning. This means knowing which version of an API is in production at each operator, being able to notify when new versions are released, and maintaining ecosystem compatibility as much as possible.
  • Ensuring federation through GSMA Open Gateway, which uses API roaming (operator to operator) but also API aggregation. This federation will enable seamless access for customers, thus enhancing their user experience and fostering customer loyalty.

Numerous API aggregators have begun establishing platforms for CAMARA APIs, facilitating the integration of APIs from various operators. This results in a unified and smooth access experience for the users. Some notable examples include:

  • Nokia: They’ve developed a ‘Network as Code’ platform, which can be found at the following link.
  • Microsoft: They’ve introduced the ‘Azure Programmable Connectivity’ that powers network-aware programming. More information is available at this link.
  • Vonage: They offer a suite of communications APIs that can be found at this link.

In essence, CAMARA’s future is rooted in the broadening of its API offerings, fortifying its governance, ensuring API lifecycle consistency, and fostering federation to enhance customer experience.

Introduction

Young demographics, predominantly consisting of Millennials and Gen Z, have emerged as key consumer segments in the market. Their digital acumen, a strong affinity for authenticity, and unending pursuit of innovative shopping experiences are redefining the consumption landscape. Recently starting work after completing his undergraduate degree in computer science, Rithu, a 22-year-old Gen Z consumer, was browsing the spatial web one day in search of a new, unique, and stylish watch. He stumbled upon a website that utilized generative AI to curate a selection of luxury watches tailored to his preferences.

Rithu was impressed by the AI’s ability to cater to his taste. He found a watch that he loved and clicked on it. A digital trigger, such as a QR code, on the website transported an AR model of the watch to his mobile device, allowing him to try it on in real-time and envision it with various outfits.

Introduction

With the emergence of artificial intelligence (AI) and the rise of edge computing, new doors have opened, paving the way for real-time solutions and improved operational efficiency. The digital transformation sweeping across the telecommunications sector has been nothing short of fascinating. In particular, the melding of artificial intelligence (AI) and edge computing offers telecom companies some truly groundbreaking opportunities. In this article, we invite you to journey with us into the ‘art of the possible,’ as we examine a future where Generative AI and edge computing redefine telecommunications operations when combined with modern OSS/BSS platforms.

The Meeting of Three Worlds

Generative AI

Generative AI is a branch of artificial intelligence that uses machine learning models to produce content. It is called “generative” because it can create new content, such as images, music, speech, or text that is similar to the content it has been trained on. ChatGPT, a creation of OpenAI, is a type of generative AI. More specifically, is a powerful language model that can generate human-like text based on the input it receives. It’s been effectively utilized in various applications, ranging from dynamic chatbots to intelligent content-generation tools.

Edge Computing

Edge Computing is a concept that brings computation and data storage closer to the location where it’s needed. This improves response times, reduces latency, and conserves bandwidth—valuable assets for real-time applications. Edge computing breaks free from the traditional data processing model of sending raw data over long distances to a centralized location. Instead, it emphasizes on processing data near the edge of the network where the data is generated. In doing so, it speeds up the response time, enables real-time data analysis, and reduces the load on the network.

Operations and Business Support Systems (OSS/BSS)

Operations Support Systems (OSS) and Business Support Systems (BSS) platforms are at the heart of telecom companies’ digital transformation. Network management, service delivery, customer care, billing, revenue management – you name it, and these platforms have it covered. The backbone of telecom operations, these platforms ensure customers enjoy uninterrupted services. Now, picture a future where these platforms are integrated with a large language model like ChatGPT. Operators can interact with the platform through a conversational interface, speeding up operations, trimming costs, and ramping up service delivery quality.

When we bring AI models like ChatGPT right to the edge of the network, or mesh them into the OSS/BSS system, they can chat with data and users almost instantly. It’s like a two-way street where the speediness of edge computing gives a practical boost to AI, and the braininess of AI makes the most out of the data crunched at the edge. This powerful combination could drive significant operational transformations, and fuel a new generation of intelligent, responsive services. However, there’s a significant hurdle to overcome: the sheer size of AI models. With their high resource demands, these models present a challenge for deployment on edge devices, which often have limited resources.

Optimizing AI Models for Edge Computing

The answer to this problem lies in techniques such as model pruning, quantization, and transfer learning. Model pruning is about cutting out unnecessary information from the model, shrinking it down to size and speeding it up, all without hampering its accuracy much. Quantization curtails the numerical precision of the model’s parameters, making the model more compact and less resource-hungry. Lastly, transfer learning lets a large-scale task-trained model fine-tune for a specific task, saving on resources required for training.

Transformation Use Cases for Telecom Providers

With the integration of AI, Edge & OSS/BSS platforms, the future of telco operations looks promising. Consider a telco network operations and engineering team that deployed AI-boosted network probes and now can play a proactive role in network management, detecting potential snags before they impact service quality.

Now, AI-empowered network probes have brought about a paradigm shift in network management. These probes are the telecom company’s eyes and ears, continually examining network performance. The AI’s predictive capabilities identify anomalies, potential issues based on data usage and network traffic patterns. So, if the system sees an upcoming network congestion during peak hours, it takes charge, rerouting traffic or adjusting network resources to avoid any service disruption. And why stop there. This predictive maintenance model extends to hardware too. By analyzing past data on equipment performance, the AI can foresee when a device is likely to fail, prompting preventive maintenance. The result? A drastic drop in network downtime and a huge leap in service quality while also driving business operation optimization by reducing the operational complexity currently required when addressing these issues.

Customer Service Like Never Before | Use Case: 2

On the customer service front, it’s a whole new world with ChatGPT-enabled devices. The telecom can now offer its customers immediate, tailored customer support, all without needing a massive call center team. Imagine a customer struggling with their home Wi-Fi. Instead of a frustrating wait on a customer support call, they directly chat with the ChatGPT-enabled device, which walks them through basic troubleshooting steps. Be it resetting the router or tweaking the Wi-Fi channel, the AI steps in to help based on the problem’s symptoms described by the customer. In case the issue is more complex, rooted in a broader network problem, the device, drawing from the AI-enabled network probes, keeps the customer updated about the problem, the ongoing resolution efforts, and the estimated time for restoration of normal services. By taking routine customer queries and issues off the hands of human customer service representatives, the company not only enhances customer experience but also redirects human resources to tackle more complex issues. This results in greater efficiency and substantial cost savings.

These detailed use cases shed light on the power of integrating Generative AI, Edge and OSS/BSS platforms to truly revolutionize telecom operations. It’s a sneak peek into the future of the telecom industry.
