5G and the future of cellular vehicle-to-everything (C-V2X) services

October 08, 2021

Cellular Vehicle-to-Everything (C-V2X)

The automotive sector is on the brink of a digital revolution with the commencement of 5G, bringing new opportunities for cellular vehicle-to-everything (C-V2X) technology. Next-gen capabilities such as ultra-reliable low-latency communication (URLLC) and high bandwidth are set to transform connected cars and, ultimately, the way we travel.

Existing cellular technology addresses some V2X requirements, so what makes 5G so different? Combined with fast-developing AI and sensor technologies, 5G will enable completely autonomous vehicles. This means the possibility of eliminating or minimizing road accidents by enabling vehicles to share data in real-time and avoid accidents. In addition, 5G-powered self-driving cars will also vastly improve vehicular performance through energy optimization, ensure traffic efficiency, provide faster routes through accurate route mapping, enable safer roads by letting drivers “see” beyond their visual horizon, and much more. V2X will not only help vehicles communicate with each other and prevent accidents and hazards, but it will also help protect pedestrians with the PC5 interface integrated into their smartphones.

The result: significantly improved quality of life and tremendous monetary savings.

V2X capabilities and transmission modes

The connected cars of today have been evolving for years to become increasingly connected, intelligent, autonomous, and efficient. Apart from reducing latency and enhancing safety, cellular V2X also brings new capabilities to the table.

As a part of 3GPP release 14, V2X includes two transmission modes that collectively enable several use cases:

Direct C-V2X (Cellular V2X) – operates in its own 5.9 GHz spectrum that is independent of mobile networks. It includes the following use cases:

  • Cars connecting to each other – Vehicle to Vehicle (V2V)
  • Cars connecting to pedestrians – Vehicle to Pedestrians (V2P)
  • Cars connecting to infrastructure like street signals – Vehicle to Infrastructure (V2I)

Vehicle to Network (V2N) – relies on traditional licensed mobile spectrum

In Release 16, too, direct C-V2X can operate without dependence on cellular networks. However, 5G connectivity helps build an ecosystem of highly reliable and accurate devices that enable autonomous vehicles. These include sensors, cameras, light detection devices, real-time car-to-car communications, and more. With 5G’s ability to support a large number of connected devices in a small geographical area, vehicles will be able to access more data about their surroundings.

C-V2X use cases enabled by 5G

The V2X ecosystem enables a broad range of services for connected car environments, and 5G takes accuracy to new heights. Some high-value use cases include:

  • Cars connecting to cyclists
  • Traffic lights broadcasting signals to cars
  • Dynamic maps in real-time
  • Central planning systems to coordinate traffic flow
  • High-density platooning or cars driving in close proximity to safely optimize road space
  • Positioning and ranging
  • Identifying empty parking slots
  • Hazard warnings
  • Cooperative driving
  • Collecting tolls without drivers having to stop at physical checkpoints

Why it demands an edge core

Today, autonomous cars like Tesla and Zoox are highly advanced and require mission-critical low-latency. 5G URLLC enables them to fully meet their potential. The 5G edge core is essential in enabling mobile network operators to cater to 5G connected cars by helping keep latency low, maintaining safety even for vehicles driving at high speeds.

How does 5G core enable V2X?

An edge core with high transaction per second (TPS) is imperative for C-V2X. Alepo’s 5G Converged Core provides V2X support, including V2X subscriptions and policies, the capability to configure and maintain V2X subscription parameters, and more. It allows UEs to be authorized for V2X capability in both EPC and 5GC. UEs can be classified into two types – vehicle and pedestrian – each having its own QoS parameters.

Alepo’s Policy Control Function (PCF) will help configure policies for vehicle and pedestrian UEs. The operator can launch innovative V2X services by defining parameters such as RAT, transmission profile, communication mode, and signaling protection mode. Individual services can then be associated with a V2X policy, customizable for different geographical areas and radio parameters.

With Alepo’s Subscriber Data Management (SDM) agent portal, each individual subscriber profile can be enabled for V2X services. This flexible configuration will enable the operator to achieve optimized end-to-end V2X connectivity.

Where we’re headed

Cellular vehicle-to-everything provides a host of benefits for all involved parties: vehicle manufacturers, drivers, pedestrians, those in charge of traffic operations and management, and, of course, 5G network providers. 5G enables the end-to-end delivery of V2X services, ensuring high ROI.

C-V2X can be rapidly deployed as it is compatible with LTE base stations. 3GPP standards help provide a roadmap for operators to evolve from LTE to 5G, ensuring a highly scalable and future-proof investment. Operators can leverage their existing network infrastructure for the initial rollout of services, and gradually transition as they evolve their networks.

It will be a while before the autonomous car ecosystem is fully functional. However, the technology is ready and communications service providers should invest in the necessary infrastructure now. Trials should be conducted to ensure the reliability and feasibility of the ecosystem.

Four key enablers for 5G monetization

Four key enablers for 5G monetization

Four key enablers for 5G monetization


August 05, 2021




Operators today provide connectivity to millions of people who are embracing a more digital lifestyle. They are also facilitating this shift for enterprises as they undergo digital transformation. To make their 5G investments profitable, CSPs need a monetization strategy that takes a multipronged approach. In addition to direct monetization, they must include partnerships, digital ecosystems, as well as unique and innovative business models. 5G monetization demands that communications service providers (CSPs) reshape and evolve their revenue management systems to ensure they can support complex B2B, B2C, and B2B2X services. So, what are the key enablers for this change?

5G use cases ready to be monetized 

5G means CSPs will be able to offer a host of new services that require advanced monetization platforms, new business models, and new ways of thinking from traditional voice and data subscriptions. These include services enabled by 5G capabilities such as:

  • Enhanced Mobile Broadband (eMBB): enables CSPs to handle ever-increasing data rates, user density, and traffic capacity.
  • Massive Machine-Type Communications (mMTC): enables the IoT ecosystem, where a large number of devices are connected to the network with varying policies.
  • Ultra-Reliable and Low Latency Communications (URLLC): caters to latency demands, especially for mission-critical and safety-critical applications.
  • Network Slicing: enables operators to use shared physical infrastructure to create multiple autonomous networks, each one catering to different QoS requirements for bandwidth, storage, processing power, and more.

The key enablers for 5G monetization

To cater to the needs of their individual and enterprise customers, and to capitalize on the possibilities of 5G, CSPs need to focus on these four key enablers:

Platform-based business model

As the 5G ecosystem expands the services and applications that can be consumed through the network, CSPs need to evolve their business models to serve as platforms that connect consumers with producers. A platform-based business model enables operators to build a wide range of industry-specific business models based on consumption (APIs, insights, and so on), use of shared infrastructure, customer journeys, and more. Operators can also set up digital ecosystems using the platform business model. These ecosystems or digital marketplaces connect businesses with consumers.

5G operators can leverage their existing infrastructure to forge diverse partnerships and offer a platform to producers, manufacturers, retailers of products and services. Network slicing enables CSPs to support and monetize these services. These partnerships can span across industry verticals such as connected cars, smart cities, industrial IoT, and more.

CSPs today are associated with multiple diverse service chains and can leverage their customer data and analytics to create highly profitable platforms that are mutually beneficial for customers and the providers of the service. They can be used to introduce more advanced offerings. For instance, Telefónica UK provides an insurance offering called O2 Drive, leveraging customer data insights to create contextual offers at better rates. The app uses GPS tracking to monitor customer journeys, giving each customer a score to tell them how safely they drive and providing tips to improve.

Robust partnership ecosystem

One of 5G’s core transformative abilities is in enabling service providers to forge diverse partnerships, thus enabling B2B2X ecosystems. 5G and IoT open business opportunities at multiple levels, with business models such as shared infrastructure, revenue-sharing, connecting multiple devices on a single network, and more. Operators can monetize partnerships based on SLAs and QoS, volumes, product/service type, inventories, infrastructure use, API and service consumption, and so on. Partners can, in turn, implement subscription- and transaction-based models, charging consumers based on their usage in terms of time, volume, output, and more.

CSPs can facilitate and monetize diverse and advanced telco as well as non-telco applications, building a partner ecosystem that spans across industries. Use cases such as road safety with self-driving vehicles and smart traffic management hold immense ROI potential. Logistics companies can be provided platforms to maximize business efficiency through real-time fleet tracking, route and fuel optimization, and more. Smart grids and utility providers can use data from IoT and connected devices to manage distribution. Healthcare professionals can benefit from platforms that enable telemedicine and remote surgeries. Agriculture can employ connected devices such as drones, sensors, and cameras to monitor soil and crop quality. Manufacturing units and factories can connect all devices on the floor from larger machines right down to a screwdriver to optimize efficiency. For retail applications, operators can help enable smart home portals and apps, digital ecosystem platforms, and much more.

Customer-focused innovation

Customer experience (CX) is a major driver for success today, compelling operators to shift their focus to customer service and service monetization in all aspects of their business, from designing products to the partnerships they build.

Ensuring good CX includes innovative business offerings, digitized experience, high network performance, service availability, and reliability. It also means billing, charging, settlement, customer support processes need to be CX-driven. Operators must look at automating CX by integrating artificial intelligence (AI) in their back-office processes such as order management as well as by implementing chatbots and automation in their payment and self-care apps.

So, how do operators monetize CX? A major part of it is ensuring simple and easy-to-implement pricing structures. Offering asset-light business models is especially beneficial to enterprises, where CSPs can provide the underlying IT and charging infrastructure to businesses, granting them full control of the services they offer to their consumers without having to invest in their own infrastructure.

Monetization models can be based on a host of different parameters depending on the applications, such as UE/MAC address for IoT and I-IoT applications, infrastructure use, inventories, geographical locations, time of day, demand, and more.

SBA core driven networks

SBA architecture with 5G core and cloud infrastructure are key enablers to the network, helping launch advanced services like URLLC, network slicing, and more. Network slicing is set to revolutionize how networks are used and monetized. And while sharing network resources means more efficient use of the infrastructure, it demands advanced charging systems to cater to the diverse use cases it supports. One slice may demand low-latency QoS, while another demands ultrafast speed, and a third demands high bandwidth. Monetizing these network slices demands dynamic near-real-time charging and policy control.

In addition to QoS, 5G monetization platforms enable charging for network use, based on the number of connections, data frequency, real-time versus non-real-time operations, location precision, and more.

Solutions that maximize 5G monetization capabilities 

In consumer as well as enterprise applications, 5G supports endless possibilities of business models and charging use cases. They will be required to support online as well as offline charging, scaling to handle the demands of IoT billing so they can charge small amounts at a massive scale. They will also need to support a range of revenue-sharing arrangements with n-level hierarchies. CSPs will need to ensure they are constantly innovating to support charging with evolving services like on-demand network slices.

As CSPs make the transition to 5G, successful monetization relies largely on the flexibility of an operator’s billing, charging, and policy infrastructure systems to support multiple pricing models. They also need to implement a next-gen partner management solution to handle diverse partnerships. Implementing a future-proof digital BSS/OSS infrastructure helps begin their journey of digital transformation, enabling them to get the most out of their 5G monetization infrastructure.

As more and more industries begin to digitize their businesses and use cloud-based infrastructure, they need robust and reliable network connectivity to ensure they can efficiently monitor and operate their assets, support process automation, and handle large volumes of data unlike ever before. And that’s where 5G comes in.

Through private or enterprise 5G, CSPs can enable businesses to run their own secure and reliable networks. Network slicing also reduces the need for businesses to invest in dedicated infrastructure. CSPs can optimize and monetize their network by dividing it into dedicated “slices” for different enterprise customers, allocating resources depending on the use case.

Top 8 industries that benefit from 5G partnerships

Partnerships provide infinite possibilities for CSPs, though some industries are more likely to be early adopters of the technology. Some of these industries and their use cases include:


5G will revolutionize transport: a recent World Bank report states that 5G holds the potential to accelerate several evolving technologies such as sharing economy and digital platforms, electric and autonomous vehicles, and advanced business models like Mobility as a Service (MaaS). The report also says that mobility-driven demand for connectivity will likely be an important revenue stream for expanded 5G coverage, and the revenue from connected vehicles in major road corridors could potentially yield ROI within just 3-4 years.

Autonomous vehicles will improve road safety and be especially viable on closed campuses in the near future. Smart traffic control with real-time management through connected traffic lights will alleviate traffic congestion. Extending route-mapping technology to transport fleets will improve efficiency and provide real-time updates to commuters on transit times and/or delays. Connecting public places like stadiums with public transport systems will enable them to anticipate higher demand during events.

    The advantages of 5G service-based architecture (SBA)

    The advantages of 5G service-based architecture (SBA)

    The advantages of 5G service-based architecture (SBA)

    18th of March 2021

    An introduction to 5G service-based architecture

    5G brings transformational changes to the core network with a modular and cloud-native approach. One key advancement is that it upgrades the traditional telco architecture to Service-Based Architecture (SBA), enabling more flexible service development.

    Introduced to improve the modularity of the network system, SBA lets network elements or network functions (NFs) in 5G communicate with each other over a service-based interface. It allows the decoupling of NFs with more precise functionalities. Each NF provides a set of services to another NF in the SBA. These NFs communicate with each other using a more open REST-based interface rather than traditional telco protocols such as Diameter.

    What does this integral change in network architecture mean for telcos?

    The SBA offers a host of benefits, including:

    • Deploys as containers orchestrated by Kubernetes, allowing the core to run on non-proprietary infrastructure
    • Lets new software vendors plug-and-play their NFs for a best of breeds approach
    • Enables network slicing, with dynamic and efficient resource utilization
    • Simplifies operations using application programming interface (APIs)
    • Leverages the use of harmonized protocols such as HTTP/2 and its well-developed security mechanisms
    • Facilitates seamless integration of third-party applications with the core network

    SBA offers a host of benefits

    How network functions communicate in SBA

    Every NF in the SBA acts as a service producer and a service consumer for each NF. All NFs communicate with each other using one of two mechanisms:

    • Request-response mechanism: here, a consumer NF requests a producer NF for services over HTTP/2 request, and the producer NF complies.
    • Subscribe-notify mechanism: a consumer NF subscribes to certain events of the producer NF, and the producer NF notifies the consumer NF once the particular event occurs.

    All of this communication is always completed using JavaScript Object Notation (JSON) objects.

    The Network Repository Function – a standalone NF – acts as a unified NF repository and an internal mediator between NFs for operations such as discovery and status tracking of NF instances. For instance, if the Access and Mobility Function (AMF) wants to communicate with the Session Management Function (SMF) to establish a data session, and needs certain information about the SMF (including NF type, FQDN/IP address, endpoint information, services supported, and more) to ensure its communication with the SMF is seamless, it requests this information from the NRF. The NRF responds with the required data, facilitating smooth communication between the two.

    The SBA provides an underlying REST-based stateless transaction framework for previously stateful services.

    From the development standpoint, interfaces (APIs) for SBA are defined with Interface Definition Language (IDL). The interface definitions are written using YAML, and are language- and platform-independent, reducing development time and effort. They are utilized by the producer NF and consumer NF to ensure that communication between them is standardized and harmonized.

    The full potential of 5G SBA

    5G SBA allows any third-party application, referred by 3GPP as Application Function (AF), to interact with 5G NFs in a secured manner. Another NF – Network Exposure Function (NEF) – acts as a mediator for external communication. For example, the AF will subscribe to AMF events via NEF, the AMF will notify the NEF once the event occurs, and the NEF will then notify the AF. This is vital in enabling several next-gen use cases such as precise indoor navigation for complex buildings such as airports, train stations, hospitals, malls, trade shows, offices, industrial areas, and more.

    A 5G standalone (5G-SA) network will leverage the full potential of service-based architecture, elevating the consumer’s mobile network experience while also opening a host of monetization and partnership opportunities for MNOs.

    Why 5G standalone core needs to be on every operator’s roadmap

    Why 5G standalone core needs to be on every operator’s roadmap

    22nd of October 2020
    By now we all know that 5G’s ultrafast speeds, high bandwidth, and low latency will open a world of opportunities, its advanced applications transforming virtually every industry. From manufacturing, healthcare, and the Internet of Things (IoT), to AR, VR, and gaming, the possibilities are endless. Service providers have two ways of transitioning to a next-gen network: 5G NSA (non-standalone) and 5G SA (standalone), with SA being the end-goal. 5G NSA (4G LTE EPC plus new RAN) remains the strategy to quickly launch high-speed 5G broadband, yet lacks the new architecture and functionality that will allow 5G to fulfill its visionary use cases.

    Unlike 5G NSA, which reuses the Evolved Packet Core (EPC), 5G SA uses cloud-based and Service-Based Architecture (SBA) that optimize network infrastructure with virtualized network functions (NFs), enabling operators to launch differentiated services, ensuring a high quality of service.

    5G NSA: step one in 5G launch

    The most popular choice of service providers to deploy 5G is 5G NSA, which is 5G radio using an existing 4G EPC. This option is considered the most viable and cost-effective. The only condition is that the 4G EPC needs to be 3GPP Release 15-complaint with additional functionalities to support dual-radio connectivity. This will enable operators to seamlessly launch 5G services and offer high-speed internet and improve access capacity.

    5G NSA focuses on offering higher data speeds and improved radio coverage in densely populated areas, helping CSPs rapidly market 5G to gain a competitive edge. However, it does not offer many of the advanced use cases possible with 5G SA, such as ultra-reliable and low latency communications (URLLC) and massive machine-type communications (mMTC).

    5G-SA: the path to full 5G benefits

    The 3rd Generation Partnership Project (3GPP) has revamped core network architecture, having moved away from traditional telecom protocols to more open, modern SBA. The 5G Core comprises multiple NFs, each responsible for specific core network functions. These NFs use REST-based APIs to interface with each other over HTTP/2 protocol, which is collectively referred to as the Service-Based Interface (SBI).

    5G SA key components

    5G SA key features and components

    With the sheer number of use cases it supports and the forecast for devices, traffic is far more dynamic in a 5G network. And so a robust underlying core network is necessary for the network to swiftly respond to demands. 5G SA enables just that. Some of its key features:

    Multi-vendor ecosystem opens the doors for new vendors, who are not just restricted to the telecom sector, or in the legacy core. The adoption of new technologies that are in-line with modern infrastructure such as REST-based (HTTP/2 or Open APIs) widens the scope for innovative vendors to contribute and revolutionize network operations and processes.

    Service-Based Architecture defines key 5GC components as NFs that integrate with each over modern APIs that support multiple varied core network functions.

    Control and User Plane Separation (CUPS) enables independent scaling between the control plane and user plane functions, facilitating flexible network deployment and operation. For instance, if the data traffic load increases, more data plane nodes are added without affecting the functionality of the existing control plane.

    Network function virtualization (NFV) allows virtualizing entire network functions and appliances using standard vendor-neutral hardware and IT infrastructure in the 5G network. It helps operators achieve a faster service life cycle, rapid deployment, scalability, operational efficiency, agility, and more.

    Network slicing enables operators to build multiple dedicated networks to cater to different business verticals with diverse requirements of high-bandwidth, ultra-reliability, low-latency communication, and more.

    Multi-Access Edge Computing (MEC) distributes computing resources along the communication path using decentralized cloud infrastructure. MEC brings data and computational capabilities closer to the source and network edges such as users’ devices, IoT devices, vCPEs, and more.

    Some key components include:

    Unified Data Management (UDM) enables managing all subscription-related data for authorization and access services.

    Unified Data Repository (UDR) stores all structured data on a flexible and highly available platform, enabling the network to readily respond to critical demands in real-time.

    Policy Control Function (PCF) is evolved from the PCRF of legacy networks, providing policy assets to handle access mobility related to policies, as well as handling data- and application-related policies. It enables advanced plan and policy customization for 5G use cases.

    Network Repository Function (NRF) keeps a record of all network function instances in the network and helps automate the functioning of NFs.

    Network Slice Selection Function (NSSF) plays an essential role in network slicing, dynamically selecting slices based on real-time information.

    Network Exposure Function (NEF) ensures information is securely translated and communicated from external applications. It is fundamental in the authorization for any access request received outside of the 3GPP network, thus ensuring the network supports use cases like cellular IoT, edge computing, and more.

    Business benefits you can derive with a robust 5G SA solution

    A 5G SA solution is meant to enable service providers to adapt to key technological changes like a cloud-native and microservice-based architecture, helping achieve operational excellence while maximizing ROI. It can facilitate:

    • Rapid introduction of new services without interfering with existing services
    • Scaling to support changing network demands and growing subscriber bases
    • Offering differentiated services with high QoS
    • Automating functions like network slicing
    • Lowering operational costs
