Nokia Siemens Networks educates the market and pushes its solution for the mobile signaling problem for long time now, as many operators say it is a major problem both in terms of performance (traffic and long-living sessions) and well as battery draining issue for subscribers. This becomes even more relevant to NSN now, as mobile broadband becomes its main business focus (here).
A new post to the vendors' blog by Gerald Reddig (pictured), Global Marketing Manager, shows how "A European 3G network is benefiting from a 30% signaling traffic reduction, three months after Network Controlled Fast Dormancy (NCFD) was implemented by Nokia Siemens Networks .. Nokia and Apple decided early on to support NCFD on their smartphones [here], with Blackberry [here] and Android OS device [here] manufacturers like Samsung, LG and Sony Ericsson following suit"
",, Standardized in 3GPP Release 8 [see below], Nokia Siemens Networks’ Network Controlled Fast Dormancy or NCFD aids by acting as a more intermediate state: one with less signaling and faster reconnections"
"Nokia Siemens Networks’ Smart Labs [here] tested popular over-the-top (OTT) VoIP applications running on different smartphone operation systems. One of the results was the huge signaling load caused by VoIP applications in non-NCFD enabled smartphones – 600% more signaling traffic"
