Nokia Siemens Networks continues to provide valuable information on traffic loads caused by signaling (see a related recent post - "VoIP Signaling Crashed NTT DoCoMo; Asks Google to help" - here).
This time, an article by Gerald Reddig (pictured) from Mobile Broadband Marketing, looks at ".. existing 3G smartphones that have been tested in our Nokia Siemens Networks Smart Labs using OTT Voice over IP applications Nimbuzz, GoogleTalk and Skype, the issue seems to be more about different smartphone behavior. This includes the signaling load during a Skype voice call on Samsung´s Android phones compared to Nokia phones and iPhones".
"The Android phones generated 600% more signaling traffic during VoIP calls .. These impressive results have recently convinced a number of device manufacturers using an Android operating system (OS) or a Blackberry OS to step back from proprietary device driven Fast Dormancy and move on to standardized Network Controlled Fast Dormancy .. As always-on OTT applications proliferate, developers and handset manufacturers will increasingly have to look at new ways to reduce signaling load".
