This article presents system design arguments to re-think the current mobile telecommunication network architecture. Undeniably, 5G has seen tremendous efforts in Access and Core Network domains to design a flexible and modern system, which aims to allow to vendor-multiplexing within the deployment of a single network and to scale (ideally) on demand. However, the vision to utilise cloud-native orchestration and operation procedures combined with microservice-based software architecture realisations did not materialise in the telco domain as of yet. This article focuses on the current system architecture, combined with proposed 6G technical Key Value Indicators, to demonstrate how 5G hinders the full end-to-end utilisation of Service-Based Architecture, ultimately allowing more end devices to utilise this standard to access services of any sort and any Quality of Service characteristic.
