How O2 Stamped Out Signaling Noise

Telefónica UK Ltd. 's O2 learned the hard way about what excess smartphone signaling traffic can do to its network when a surge in smartphone users strained its 3G network in London at the end of 2009. (See 02 Felt iPhone Crunch Too.)

Not long after having these 3G service troubles, the operator added signaling as well as radio access network capacity with Nokia Networks to cope with increasing numbers of smartphone users on its network, particularly in London. (See O2 Boosts Capacity for Smartphone Surge.)

In an interview with Light Reading Mobile from February (shortly before the the Mobile World Congress in Barcelona), Telefonica Europe CEO Matthew Key discussed the effect that the influx of smartphone users had on his network, how O2 dealt with the new kind of traffic patterns and what O2 learned.

So why bring up this interview now? Given that the signaling traffic burden is such a hot issue, the insight and experience from an operator with signaling battle scars is valuable.

re: How O2 Stamped Out Signaling Noise

As an O2 customer regularly in central London, the performance has improved in teh past year or so. I recall the mid-late 2009 era when, more than once, I couldn't follow the soccer games in real time on my phone under the table in a bar/restaurant while I was supposed to be listening to someone chatting... Broccoli Brown can attest to that!
