It will with Nokia Networks 3G Application Aware RAN
We are very visual and social creatures – from seeing images in the flickering firelight to telling stories, from painting in caves to sharing current-day selfies, films and television shows. Humans have always been attracted to pictures, especially if they move and hence imitate real life more closely. We like interaction and visualizations, which have been changing in form and function ever more quickly in the smartphone era.
So it’s no surprise that video applications in particular have come to dominate mobile communications. People love to consume and share information with their smartphones and increasingly run multiple applications in parallel. To cater to this, 3G networks need to move from monolithic treatment of users and applications to a network which operates at the “speed of the user” and which has the flexibility to adapt as applications and media types change in popularity – and all this in a multi-tasking environment.
Operators rightly ask how they can possibly cope with the incessant demand for more data from increasingly diverse services. They also need to handle many different application and content types, while also prioritizing foreground applications over others. Traditionally, pricing, capacity expansion, speed and volume control, content optimization and user differentiation have been used to manage traffic growth – but these methods have their limitations, particularly when it comes to meeting the needs of different application types and reacting instantly to congestion.
Prioritizing Quality of Service
The solution is to deploy Quality of Service (QoS) based application differentiation. This allows operators to prioritize application traffic as and when needed. It helps keep subscribers loyal by offering them a better experience, while at the same time increasing efficient use of the network.
Nokia Networks launched its 3G Application Aware Radio Access Network (RAN) in 2013, with which the core network detects data applications and informs the RAN about the user’s QoS demand. The RAN can then prioritize browsing or streaming media content, giving the user a better experience while browsing web pages or watching videos.
Recent updates now allow operators to create personalized packages designed to support particular applications with the quality of service and experience they need, as well as offering pricing plans to match quality.
The solution is compatible with all 3G devices and is currently licensed by more than 50 operators worldwide with several field trials in progress.
A further development, known as In-Bearer Application Optimization, provides different priorities for applications being used at the same time. For example, multi-tasking users can have their web browsing prioritized ahead of downloading large e-mails.
By sharing existing network capacity more efficiently, Nokia Networks’ technique allows operators to deliver an excellent user experience, even if the network capacity cannot handle sudden traffic peaks. Using these two techniques together can achieve almost 90% faster download rates.
