1. Clients: Moving from Homogeneous to...

As we have been updating our solutions for Service Provider WiFi, one of the key questions
that we needed to answer concerned the assumptions regarding client functionality. The
issues raised are perhaps broader than just SP WiFi and key to driving a coherent approach
to Mobile SP architectures - can we assume that the client functionality is homogeneous
or do we need architectures which accept that there will be a heterogeneous array of client
capabilities?
Clearly, GSM was built on an assumption of a standardized client - indeed the MMI is
standardized (in 3GPP 22.030) such that when we enter *#06# we are all presented with the
device's IMEI. Perhaps we can see UMA/GAN in the same light, trying to extend the same
approach to dual mode phones - defining an architecture which assumed a homogeneous
client with integrated UMA/GAN capabilities.
Now with 3GPP defining IEEE 802.11U connection managers, IPSec/IKEv2 I-WLAN,
DSMIPv6 for non-3GPP access and IP Flow Mobility based on MIPv6 signalling extensions,
we need to appreciate that future architectures can no longer assume a homogeneous
client environment. We need SP WiFi architectures which incrementally provide enhanced
functionality depending on client capabilities but which do not exclude users in the "all-or
nothing" approach of UMA/GAN.
If this is true for SP WiFi, then how does such learnings impact the architectures for
supporting RCS, VoLTE mobile video and other clients focused on monetization rather than
optimization?

I just got forwarded a link to Dean Bubley's blog from June 25th - http://

The part that resonates with me was... "As always, divergence will be more important than
convergence. Multiplicity will rule, not unification."
I think this really is a fundamental shift - not just for SP WiFi clients or VoLTE realizations,
but an area which will critically impact how mobile operator's are going to have to address all
future monetization opportunities.

Hi Mark
Thanks for the link.
To an extent, heterogeneity has crept in ever since SMS became popular - the user interface
& experience is very different on various brands of devices. I remember an operator
standing at a conference in 2005, saying that SMS revenues on Brand A of phones was 3x
that on Brand B, as it was a much simpler & more seamless experience that encouraged
consumers to try, and become loyal, to the service.
Connection management is even more problematic - it's an area that I've been following for
a while, and see that the underlying complexity of networks is outpacing the ability of the CM
to evolve fast enough. In particular, because WiFi is unlicenced, and effectively has "Private
Mode", "Public Mode" and "Operator Mode", the number of scenarios is proliferating even
further. Add in the (currently very difficult) ability to discriminate macro vs. femto connection,
and perhaps the ability to have 2+ connections open simultaneously, and the problem gets
deeper still.

The divergence / convergence theme is one I have been espousing to clients for years.
Often the "elegance" of technical convergence is a poor fit for useability - or even the fickle
hand of fashion. Convergence regularly fails to address user psychology about combining
things that "ought" to stay separate. As an analogy - it may make economic *sense* to have
a hybrid, converged washing machine / toaster in my kitchen, but it would still "feel wrong".
Almost as wrong as paying for it through my monthy mobile bill.
I also see failed attempts at convergence in areas such as aggregated views of
social networks - yet another of the many reasons for the irrelevance of RCS. http://

A good example of divergence is the current viral adoption of BlackBerry Messenger among
youths in some countries. From a purist's perspective it's the wrong answer - silo'd, non-
interoperable, non-integrated, proprietary. Yet unlike its lowest-common-denominator peers,
it has a compelling *user-driven* appeal of "exclusivity" - the complete opposite of ubiquity. It
allows cliques to form, it tends to work best for the "cool kids" and so forth. And all that is an
"emergent" property, not really the objective of RIM - but like SMS, it fits with the underlying,
decomposed user social needs & psychology. (And the battery).
Divergence in mobile voice use is going to be the next trend. It's something I've been
advising various clients on recently, and should prove pretty fascinating to see evolve over
the next couple of years.
