Welcome to the introduction of the 5G Core Network! In this video, we explore how 5G's core network is designed to support a wide variety of services with drastically different performance requirements, including massive Machine Type Communications (mMTC), enhanced Mobile Broadband (eMBB), and ultra-reliable low-latency communications (URLLC). Unlike LTE, which primarily handled voice and mobile broadband, 5G is built with the flexibility to support numerous use cases through advanced technologies like network slicing, service-based architecture, and network virtualization.br br Key concepts covered include:br * From LTE to 5G Core Network: How LTE handled two main services—voice and broadband—versus 5G's broad range of use cases.br * Network Flexibility & Complexity: Learn why flexibility in 5G also adds complexity and how automation and programmability are used to solve it.br * Network Slicing: Allows for the creation of multiple virtual networks within a single physical network to handle different services.br * Service-Based Architecture: A key design principle in 5G that allows network functions to be modular and interact with each other through standardized services.br * Virtualization: Enables the core network to be decoupled from hardware, improving flexibility and scalability.br * Telecom Operators' Roles: We explore the three roles of telecom operators in 5G—Connectivity Provider, Service Enabler, and Service Provider—and how they can grow their business beyond just providing network access.br ** Connectivity Provider: Operators offering basic Internet or telecom services.br ** Service Enabler: Operators exposing network capabilities (e.g., storage, compute) for external developers to build services.br ** Service Provider: Operators building and delivering services directly to consumers, like AT&T offering streaming services.br These innovations allow telecom operators to unlock new revenue streams and play a bigger role in the growing digital ecosystem, moving beyond connectivity to enable and even provide services.br br Brief Explanation:br * Business Growth Opportunities: Learn why 5G is projected to increase operator revenue growth as a service enabler or service provider, with forecasts showing potential growth rates of 13.6 per year compared to the 1.5 growth expected for pure connectivity providers.br br * Practical Use Cases: Understand real-world examples of operators acting as service providers (e.g., AT&T offering streaming services), service enablers (providing network resources for platforms like Netflix), and basic connectivity providers.br br * Enabling Technologies: Dive into how network slicing, service-based architecture, and virtualization come together to make the 5G core network powerful and efficient, capable of handling a wide range of use cases with different data, latency, and reliability requirements.
