Securing Utilities Infrastructure

As a highly critical sector, the oil and gas infrastructure should be one of the most secure, both physically and digitally. This is not the case.

Japanese mobile operator KDDI has deployed Nokia Siemens Networks' telecoms operating system, creating the world’s first, intelligent, self-organising network. The approach automatically manages KDDI’s 3G and 4G (LTE) networks to ensure people receive a consistent voice and data service, irrespective of the network they are using.


The intelligent Self organising Networks (iSON) operates nationwide, across networks built with equipment from multiple vendors. Fierce market competition from the Far East, which has eroded hardware equipment margins, has caused vendors to adapt its business models to customer demands and market changes. Traditionally, a mobile operator would select a single vendor for end-to-end infrastructure deployment and management.


However, this is not the case today. Customer and market demands are changing and solutions providers have to adapt accordingly. In the case of KDDI, which awarded the LTE base station infrastructure to Japanese vendor NEC and the network infrastructure to Motorola (Nokia Siemens acquired the assets of Motorola in 2011), meant the vendor had to re-invent itself.


The firm had to adapt its service business model to support a multi-vendor environment. This means supporting different protocols and management formats that are vendor proprietary. Being able to adapt to a multi-vendor environment is a challenge on its own, but then adapting the service quality management layer to automatically optimise the infrastructure is even more difficult, considering the Motorola acquisition is only a year old.


“Nokia Siemens was an obvious choice when we decided to optimise our network operating processes via automation,” says Toshihiko Yumoto, vice president and general manager, network technical development division, technology sector at KDDI. “Nokia Siemens’ multi-vendor iSON helps us to efficiently service our customer’s always-on communication service, and this will be all the more important when we launch LTE later this year.”

The iSON solution uses Nokia Siemens’ advanced NetAct operations Support System (OSS) allowing the operator to automate and optimise its network operating processes across multiple technologies and vendors. The iSON is a key part of the vendor’s Liquid Net-based approach to delivering mobile broadband, whilst delivering and managing customer experience.

“KDDI’s multi-technology network from several vendors called for a solution that would address specific synchronisation and optimisation requirements,” says Scott Mottonen, head of the CDMA/LTE business at Nokia Siemens. “Our iSON solution allows for consistency and flexibility in multi-vendor environments, minimising operational costs and errors,” Mottonen adds.
