Network Socket Request Manager (NSRM)

Managing background data traffic in mobile devices.

NSRM aggregates uncoordinated data app connection attempts into fewer coordinated connection attempts without affecting the user experience. This is ensured by aggregating only those events that occur when the user is not actively using the phone which we refer to as background mode. This reduces the amount of time radios are in an active state, resulting in improved battery performance. This also significantly reduces the signaling generated by the smartphone.

Details

Mobile applications periodically update their status asynchronously, even when the user is not actively using the device – for example, when the phone display is off and not running an active audio application. This generates significant signaling traffic on the network. Bundling of these requests by delaying them for some period of time without impacting the user experience provides significant gains for the device and network.

Qualcomm has validated the benefits of NSRM using smartphone prototype devices with a mix of commonly downloaded applications. A detail of the mechanism used and performance results for NSRM is available in the Managing Background Data Traffic in Mobile Devices white paper.
