Clients: Moving from Homogeneous to Heterogeneous

  1. 1. Clients: Moving from Homogeneous to... Mark Grayson 18 posts sinceMay 13, 2009As we have been updating our solutions for Service Provider WiFi, one of the key questionsthat we needed to answer concerned the assumptions regarding client functionality. Theissues raised are perhaps broader than just SP WiFi and key to driving a coherent approachto Mobile SP architectures - can we assume that the client functionality is homogeneousor do we need architectures which accept that there will be a heterogeneous array of clientcapabilities?Clearly, GSM was built on an assumption of a standardized client - indeed the MMI isstandardized (in 3GPP 22.030) such that when we enter *#06# we are all presented with thedevices IMEI. Perhaps we can see UMA/GAN in the same light, trying to extend the sameapproach to dual mode phones - defining an architecture which assumed a homogeneousclient 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 homogeneousclient environment. We need SP WiFi architectures which incrementally provide enhancedfunctionality depending on client capabilities but which do not exclude users in the "all-ornothing" approach of UMA/GAN.If this is true for SP WiFi, then how does such learnings impact the architectures forsupporting RCS, VoLTE mobile video and other clients focused on monetization rather thanoptimization?Tags: wifi, mobile_monetization, packet_core, uma, clients Mark Grayson 18 posts sinceMay 13, 2009 Reply 1.

  2. 2. Clients: Moving from Homogeneous to...The part that resonates with me was... "As always, divergence will be more important thanconvergence. 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 operators are going to have to address allfuture monetization opportunities.- Mark deanbubley 7 posts sinceJun 25, 2009 Reply 2. Re: Clients: Moving from Homogeneous to Heterogeneous Jul 15, 2010 2:11 AMHi MarkThanks 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 operatorstanding at a conference in 2005, saying that SMS revenues on Brand A of phones was 3xthat on Brand B, as it was a much simpler & more seamless experience that encouragedconsumers to try, and become loyal, to the service.Connection management is even more problematic - its an area that Ive been following fora while, and see that the underlying complexity of networks is outpacing the ability of the CMto evolve fast enough. In particular, because WiFi is unlicenced, and effectively has "PrivateMode", "Public Mode" and "Operator Mode", the number of scenarios is proliferating evenfurther. 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 getsdeeper still.Generated by Jive SBS on 2010-11-29-07:00 2
  3. 3. Clients: Moving from Homogeneous to...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 ficklehand of fashion. Convergence regularly fails to address user psychology about combiningthings that "ought" to stay separate. As an analogy - it may make economic *sense* to havea 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 ofsocial networks - yet another of the many reasons for the irrelevance of RCS. good example of divergence is the current viral adoption of BlackBerry Messenger amongyouths in some countries. From a purists perspective its the wrong answer - silod, 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. Itallows 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. Its something Ive beenadvising various clients on recently, and should prove pretty fascinating to see evolve overthe next couple of years.Dean BubleyFounder & DirectorDisruptive Analysisinformation AT disruptive-analysis DOT comGenerated by Jive SBS on 2010-11-29-07:00 3
