Ericsson - Improve QoE by Radio Access and Transport Network Interaction

A new paper by Stefan Dahlfort [pictured], Shahryar Khan, Jonas Rosenberg, Anton Smith, Shuo Yang Y, Mats Forsman, and Tomas Thyni, all from Ericsson, presents a new concept for QoE Imprvement.

"The demand for mobile-broadband services is causing network congestion. While such congestion tends to be temporary, it has a significant impact on user satisfaction. By adopting a holistic approach to network architecture, one that enables the radio and transport domains to share information, proactive measures to avoid congestion can be put into place, increasing the number of users at or above the desired QoE level"

"Our concept for radio access and transport network interaction [RTI] is a two-step process that first attempts to proactively avoid congestion and then address any congestion issues that cannot be avoided. For example, if information about transport path congestion can be included in the handover decision, moving users to a cell with congested transport can be avoided. But to do this, the RAN needs to be transport aware and the transport network needs to be RAN aware"

NI Deployments [359]: SoftBank [Japan] Uses Procera for Subscriber Experience Visibility

Just before replacing its CEO (here) Procera Networks announces a high profile customer for its DPI and analytics solutions (Perspectives).

"SoftBank has deployed Procera’s PacketLogic solutions to enhance its LTE service offerings in Japan. Procera was selected to replace the existing traditional analytics and assurance vendors [see other solution they use below] due to the enhanced Subscriber Experience visibility that Procera was able to provide for the operators on top of traditional mobile analytics. 

Softbank is committed to providing a superior subscriber experience as broadband usage increases with the popularization of smart phones and tablets .. This deployment was delivered to SoftBank in partnership with ITOCHU Techno-Solutions Corporation". 

Procera reported in Q1 (here) that "For the three months ended March 31, 2015, revenue from Itochu Techno-Solutions Corp. represented 14% of net revenue" - bringing the revenues from Itochu to $2.9M in Q1 2015 (which may include other customers and represents just a portion of the revenues from the SoftBank deal),
