Telco Industry - Incident Detection and Response Alarming Best Practices

Telco

Introduction

AWS is empowering telcos to reinvent themselves— transforming from telco to tech-co while moving their core workloads to the cloud to achieve the agility, resiliency, cost efficiency, security, and sustainability they need to stay ahead. AWS helps you transition from connectivity provider to digital service provider that leverages your network to create richer relationships with customers.

Common Telco Workloads:

5G Network (Core network and RAN)

Core network and RAN provides the necessary infrastructure to deliver multimedia services efficiently and reliably. It enables the integration of voice, video, and data services into a single IP-based platform, allowing operators to deliver advanced communication services to their subscribers.

Core network workloads include Packet core, IMS (IP Multimedia Subsystem) and VAS (Value added Services) workloads. Packet core workloads include capabilities such as MME (Mobility Management Entity), AMF (Access and Mobility Management Function), S/PGW (Serving/Packet Data Network Gateway), SMF (Session Management Function), UPF (User Plane Function), HSS (Home Subscriber Server) and UDM ( Unified Data Management). IMS workloads includes Call session controller framework, HSS, Media Telecom Application server, NNI interfaces among other things.

Network IT (OSS/BSS)

• BSS (Business Support System) stacks provide functionality for Communication Service Providers to manage their customers. BSS encompasses the spectrum from marketing, shopping, ordering, charging, taxation, invoicing, payments collection, dunning, and ultimately financial reporting.

• OSS (Operations Support System) stacks provide functionality for Communication Service Providers to manage their networks, including provisioning services, managing network inventory and configuration, handling faults, and ensuring service quality levels.

While we acknowledge the broad industry definition of what constitutes OSS/BSS, the proposed architecture framework focuses on the most critical modules commonly observed in OSS/BSS deployments, and their deployment architecture on AWS.
