World’s first self-operating 3G and 4G mobile network deployed in Japan

01 июня 2012

Nokia Siemens Networks has deployed a new telecoms operating system for Japanese mobile operator KDDI that has created the world’s first, intelligent, self-organizing 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 Organizing Networks (iSON) approach from Nokia Siemens Networks operates country-wide, across networks built with equipment from multiple vendors.

“As a leader in self-organizing networks, Nokia Siemens Networks was an obvious choice when we decided to consolidate and optimize our network operating processes via automation,” said Toshihiko Yumoto, vice president and general manager, network technical development division, technology sector at KDDI. “Nokia Siemens Networks’ 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 Networks’ advanced NetAct Operations Support System (OSS) and allows the operator to automate and optimize its network operating processes across multiple technologies and vendors. iSON is a key part of Nokia Siemens Networks’ Liquid Net-based approach to efficiently managing the demands of delivering efficient mobile broadband, whilst delivering and managing a valuable customer experience.

Nokia Siemens Networks’ multi-vendor iSON provides KDDI with a unified and flexible platform as well as an integration layer for dynamic and cost efficient multivendor operations. Consolidating the OSS landscape across networks, NetAct automatically tunes the networks to be more responsive to traffic fluctuations. This saves manual effort and improves network availability. It also increases the interworking performance across 3G and LTE by automatic adaptations of the system linkage parameters such as Self configured Circuit Switched FallBack (CSFB).Mobility Robustness Optimization (MRO) automatically adapts and speeds up LTE network optimization and improvement cycle.

The company has also provided professional services for implementation, integration and customization with KDDI’s business processes.

“KDDI’s multi-technology network from several vendors called for a solution that would address specific synchronization and optimization requirements,” said Scott Mottonen, head of the CDMA/LTE business at Nokia Siemens Networks. “Our iSON solution allows for consistency and flexibility in multi-vendor environments, minimizing operational costs and errors. Moreover, providing a single view over the entire network caters also for efficient customer experience management.”
