The telecommunications sector is currently undergoing a transformative revolution across various dimensions. Emerging technologies such as the Internet of Things (IoT), 5G, and edge computing are gaining significant traction, propelling both the telecom industry and the broader business landscape into a new era.
This revolution extends beyond technical advancements, influencing the business strategies and paradigms guiding the field.
Telecom companies are transitioning from a monolithic business model to unbundling into distinct legal entities: NetCo, representing the actual network infrastructure, and ServCo, handling the customer-facing side.
This shift is facilitated, among other factors, by an emerging cloud model known as Network-as-a-Service (NaaS), empowering users to operate a network without the need for ownership or direct management of the infrastructure.
The key features of this technology are:
Cloud-native architecture which allows performances resilience, reliability, scalability and monitoring;
Network disaggregation that enables the compatibility and independence of different parts of both the hardware and the software;
AI integration to improve efficiency, reliability and security and make networks able to dynamically adapt to constantly changing environments;
5G bandwidth allowing up to 20 times the current load capabilities.
Generative AI (GenAI) represents a relatively new paradigm in deep learning, contrasting with the common Discriminative AI approach. In Discriminative AI the model is provided with data as input and it is able to regress, classify or identify patterns within it, essentially replicating straightforward human tasks. An example could be text classification: given a text the algorithm classifies its underlying topic. Generative AI takes a step beyond this, involving algorithms capable of generating completely novel data different from what they have seen in training, akin to human creativity. In this scenario, the model isn't confined to addressing a specific task; instead, it must comprehensively and deeply grasp the input data, understanding its structure and the underlying probability distribution in order to being able to reproduce them by itself. This includes the generation of diverse types of data, ranging from images that closely resemble real ones to well-structured texts or audio files. Considering the earlier example, one could perceive it as a reverse process: inputting a topic, and having the algorithm generate a corresponding text.
We have different types of models, all deep learning-based:
These models learn to compress data into a latent space corresponding to the parameters of a variational distribution and then reconstruct the data.
Composed by a generator (a network that generates data) and a discriminator (a network that attempts to distinguish between real and generated data) that play against each other in a zero-sum game.
these include encoder-decoder models as well as encoder only (BERT) or decoder-only (GPT) architectures.
Artificial Intelligence and in particular Generative Artificial Intelligence represent a powerful tool to tackle the challenges derived from telecommunication transformation and innovations as well as the increasing complexity of today’s networks. Telecom companies are progressively integrating these tools across various facets of their business, despite still being in the early stages of adoption. AI can be used in network automation, to enhance customer experience or optimize business processes.
A Network Operations Center (NOC) serves as a centralized hub for monitoring and managing telecommunication systems. When issues arise, NOC operators take appropriate actions to address them. Currently, many of these actions rely on the expertise of human operators. Technicians consistently assess the network's status and incoming alarms to determine how, where, and when interventions are needed.
Due to the high complexity of the system a very small subset of simpler actions can actually be automated, essentially rendering the work of the NOC a predominantly manual process. Furthermore, the escalating complexity of networks is posing challenges even for human operators in identifying the most effective actions. This is why a transition is taking place towards intelligent NOCs, where human supervision is augmented and potentially replaced by algorithms.
To construct an intelligent NOC, the essential components include a Reinforcement Learning (RL) algorithm and a network model.
RL, a type of Machine Learning algorithm, consists of an environment (in this case, the network) and an agent representing the algorithm exploring and interacting with the environment.
The agent learns how to act based on predefined objectives. In this case the agent monitors various variables and features of the network and responds in order to address any issues, recommend an action, optimize certain variables or minimize the risk of future failures. RL can deal with very sophisticated environments, it can continuously interact with and learn from them, making it suitable for complex and fast-changing environments like todays networks. An RL algorithm can handle a multitude of variables far beyond the capacity of a team of humans, leveraging much more intricate relationships between them; all this resulting in more effective solutions.
The environment can be embodied by a digital twin, serving as a high-precision, virtual representation of a corresponding physical entity. With GenAI we can create such interactive digital twins to train our RL algorithms without disrupting the actual architecture. Additionally, digital twins usually entail considerable expenses in terms of time, finances, resources, and data. This presents a significant drawback to the technology. To address this issue, GenAI allows us to surpass these limitations by training our digital twins using generated data instead of rigidly defining their behavior. We can even construct less complex models of digital twins that maintain the desired performance and functionality while incurring lower costs and resource utilization.
In the context of mobile networks, we are transitioning from the RAN paradigm to Open-RAN. This approach allows service providers to use non-proprietary components from various vendors, facilitated by a set of standards for device production. This shift leads to programmable, intelligent, disaggregated, virtualized, and interoperable functions. As a result, it enables network automation and management using AI and GenAI: ML algorithms for network operational copilots; autonomous network configuration and performance management; troubleshooting systems with LLMs and knowledge graphs; RAN/O-RAN systems similar to GPT.
Large language models can be used to develop chatbots that assist both customers and help desk operators. Customers can interact with the chatbot to resolve issues or initiate a ticket, reducing the workload for operators and creating more personalized experiences. Conversely, operators can leverage this technology to receive assistance in troubleshooting or obtain network status information more intuitively and efficiently.
AI can also be a great tool for supporting the development process: Assistance in DevOps (AI-driven automated testing, monitoring, automatic anomaly and vulnerability detection); Code generation tools; Documentation synthesis support tools similar to GPT.
Generative AI models can be used to generate personalized product recommendations based on individual customer preferences, purchase history, and behavior. For example, a generative AI model can be trained on customer data to learn patterns and relationships between customer attributes and product preferences. The model can then generate recommendations for each customer based on their unique profile, leading to higher conversion rates and increased customer satisfaction.
Telecom companies are also playing a key role in expanding remote healthcare services, which have become increasingly important in light of the COVID-19 pandemic. By leveraging 5G connectivity and edge computing, healthcare providers can remotely monitor patients' vital signs and offer real-time medical consultations. This technology can also be used for remote surgeries and procedures, reducing the need for in-person visits and improving patient outcomes. Additionally, the low latency and high-definition video capabilities of 5G enable the rapid and secure transmission of sensitive medical data, such as X-rays and MRIs, allowing doctors to make more accurate diagnoses and treatment plans.
