Working with its network equipment partner Ericsson, the telco has successfully implemented an automated In-Service Software Upgrade (ISSU) capability for functions in Ericsson’s dual-mode 5G Core, establishing a new architectural approach to software automation within 5G Core and cloud native technologies. The upgrade provides TPG Telecom the flexibility to initiate faster updates of new network features and significantly improve the responsiveness and execution times of end-to-end flows in its core network.

For TPG Telecom customers, the upgrade means service enhancements, including new security and reliability features, can be delivered in a faster and more stable manner, leading to less interruptions and higher network performance.

Compared to previous network upgrade mechanisms, the ISSU implementation for the functions targeted for this initial introduction of the capability with TPG provides 70 per cent faster software upgrade execution time and eliminates the need for external suppliers to assist when performing upgrades.

“This marks a significant milestone for TPG Telecom’s digital transformation journey, as we continue to build Australia’s most innovative and advanced mobile network. By harnessing new and innovative automation technologies we can improve network performance and customer experience, while also boosting security and reliability,” said Clinton Fick, TPG Telecom General Manager Core Network Applications.

“Automation enhances the efficiency of our network, while also empowering our people to redirect their time towards innovation and investment in other critical areas of our network.”

Emilio Romeo, Head of Ericsson Australia & New Zealand, says: "We are pleased to be collaborating with TPG Telecom as they unveil the successful implementation of an automated In-Service Software Upgrade (ISSU) capability enabled by Ericsson’s dual-mode 5G Core. This milestone is not only a significant shift in software automation but also heralds a new era of agility and efficiency in network management.”
