Ericsson SW Model sw structure overview
ESM is an e2e model applicable to all areas (RAN, Transmission, Core, OSS) › It consists of ›
– Base Package (BP) – Value Packages (VPs) – SW Subscription ›
Legacy (current) model is made up of basic, optional features & a separate SW mangement – Basic functionality and some optional features are part of BP when migrating to ESM – Optional features are grouped into VPs based on their values & functionlaity – SW subscription enables being on the latest SW release
Ericsson SW Model korek benefits
›
Performance – Latest SW release is an enabler for improved network performance – This is enabled by SW subspriction in ESM
›
Simplicity – BP & Some VPs compared to tens of features – Technically features remain and enabled by respective VPs that are commercially dealt with too
›
Predictibiliy – Predictible fee for SW Subscriptions
