Liquid Radio WCDMA Software Suite helps operators reduce signaling, manage the smartphone traffic boom #1GBperday$

New software applications create cognitive learning networks, enable a tenfold reduction in signaling

Nokia Siemens Networks launches new software applications for the Liquid Radio WCDMA Software Suite to help mobile broadband manage the smartphone boom and substantially reduce the network signaling overload. Smartphone users will gain faster services and longer battery life, while operators will be able to serve more subscribers on existing hardware and enjoy lower operational and capital costs.

With smartphones now outselling feature phones* and dominating mobile traffic, the amount of signaling is growing at the same time, in particular because of ‘always-on’ background applications. Nokia Siemens Networks is launching new Liquid Radio Software Suite applications to help meet capacity demand and address the signaling challenge in 3G networks. Each of these applications can be implemented with a simple software upgrade to existing networks. Together, they turn ordinary networks into learning networks that adapt to current conditions and enable a tenfold reduction in signaling load between radio and core networks.

Fast Dormancy Profiling is a new Nokia Siemens Networks technology that identifies the legacy smartphones connecting to the network and eliminates the unnecessary signaling they often create. This application significantly reduces the air interface load on the Radio Network Controller (RNC).

With Fast Cell PCH Switching, also a Nokia Siemens Networks technology, the network learns how specific smartphones are using the network services and shortcuts the signaling process for rapid call set-up, faster response from mobile broadband services and reduced signaling.

High Speed Cell FACH enables networks to support more smartphones and provide faster services for subscribers using lower data volumes. It also significantly decreases signaling load between the RNC, base station and smartphone.

By dramatically reducing signaling load, these applications free up network capacity for smartphone services. Benefits for smartphone users include faster services, less energy consumption and longer battery life.

“When people use smartphones, they stay connected to mobile broadband networks for longer periods of time and use a wider variety of services**,” said Thorsten Robrecht, VP portfolio management at Nokia Siemens Networks. “As data traffic grows, there is a huge rise in signaling between smartphones and core networks to keep services active. Coping with this signaling is critical to maintain network services and deliver an outstanding smartphone experience for mobile broadband customers.

Along with its new applications, Nokia Siemens Networks offers Smartphone Experience Optimization Service, supported by its Smart Labs capabilities, to help operators boost performance for users by analyzing the impact of smartphones in their networks, optimizing performance based on this insight, and integrating Liquid Radio Software Suite features as part of the optimization process. Typical benefits have included 50% faster loading time for web pages.
