NSN Warns MNOs: OTT Outages Increases Signaling (20X!)

A blog post by Gerald Reddig [pictured], Head of Smart Labs Marketing, Nokia Solutions and Networks, reports that "Recent OTT service outages in cloud service provided by Google hit mobile operator radio access networks with an unexpectedly high signaling load. Online services rely entirely on the service availability in large data centers provided by Google, Amazon and Microsoft, for example.

NSN Smart Labs verified that a cloud service outage can trigger smart phones to generate signaling loads up to 20 times greater than normal. This is an important heads up for mobile operators to prevent chain reactions that could lead to network outages .. For the test, NSN Smart Labs utilized one popular high-end Android smart phone. Now multiply that signaling storm by thousands of smart phones simultaneously and radio access networks would definitely be compromised".
