Mobile Data Traffic Management

Reducing power consumption and helping operators maximize data capacity.

The ever-increasing growth of data and signaling traffic generated by smartphones is challenging current networks. The user experience is also being affected by poor battery performance in smartphones. There is a real need for intelligent system selection and effective use of offload between 3G/LTE and Wi-Fi. Mobile applications need to be efficiently managed to improve battery life and reduce signaling traffic.

Qualcomm has developed a solution called Connectivity Engine (CnE) to address these challenges. CnE is a suite of low-level algorithms that enable intelligent management of device connectivity. CnE is designed to help operators better utilize their existing network capacity and improve the user experience by making smartphones and mobile devices more power efficient, intelligent and network friendly. The two main components of CnE are Network Socket Request Manager (NSRM) for efficient data application management and Wi-Fi Quality Estimation (WQE) for intelligent Wi-Fi offload.

CnE is being commercialized and made available to Qualcomm licensees as part of Qualcomm’s Snapdragon™ chipset software.

Project Features

Wi-Fi Quality Estimation (WQE)

WQE is an intelligent 3G/LTE Wi-Fi offload framework that measures Wi-Fi channel quality, backhaul quality, and detects available Internet connectivity to improve system selection.

Network Socket Request Manager (NSRM)

NSRM manages background data traffic in mobile devices by aggregating multiple connection attempts from applications into fewer connection attempts without affecting the user experience.


NSRM uses intelligent aggregation of application data requests during background mode to improve battery life and reduce signaling traffic. WQE dynamically estimates the link/path characteristics of Wi-Fi networks. Using WQE in conjunction with operator policies and user preferences, CnE makes intelligent system selection decisions between 3G/LTE and Wi-Fi. This results in a better Wi-Fi user experience and better utilization of the operator assets.
