The walled garden approach, adopted by most wireline and mobile telecom providers, has a number of key shortcomings says a new report by Pyramid Research; Transforming Telcos With IMS: The Telco Silver Bullet for an Applications-Centric World.
Eventually, voice and data will converge around an IP transport. The IP Multimedia System (IMS) is the multimedia architecture that provides interoperability.
"The walled garden approach remains the preferred option for telcos, for a simple core reason: control," comments Svetlana Issaeva, the report's author.
Using IMS, carriers can track, charge for or block subscriber access to
Internet-based services. They will be able to charge extra for
preferred handling of multimedia traffic, and allow preferential
treatment for some services and websites over others.
For all the advantages that the walled garden approach has, says the report, it does not take the full measure of the challenges telcos are facing. Walled gardens have a number of key limitations. The cost and ultimate price of quality of service and service customization and also the restrictions to subscriber choices make this model inadequate for ultimate IMS rollout, says the report.
IMS is the foundation for next-generation fixed/mobile convergence based on IP. It allows, for example, a single video clip to be played on a cellphone, laptop or television set. It allows interoperable messaging, data exchange and billing across different platforms (like a WiFi/Cellphone).
Sprint's commitment to Mobile WiMAX yesterday also brings challenges.
The Average Revenue Per User could be under attack if users dumped
Sprint voice services and went with Skype. iSkoot allows Skype calling on regular cellphones, for example. WiFi or WiMAX might provide a (cheaper) alternative route to cable or cellular VoIP services, resulting in a net loss of revenue.
The next 12 months will be critical for the future of the IP Multimedia Subsystem (IMS), as carriers begin to deploy IMS-specific systems and determine whether it can deliver on its promises, according to Heavy Reading analyst Graham Finnie.
Carrier vendors implement IMS around their own hardware and software:
- Motorola's IMS approach is based on their SoftSwitch platform for seamless mobility. Using their IMS core and MOTOwi4 wireless solution, Motorola provides IP-based voice, video, conferencing services, unified messaging, ringback tones and other SIP-based applications on multiple devices.
-
Nokia's IP Multimedia Subsystem
uses SIP (Session Initiation Protocol) to establish IP connections
between terminals. The IP connection can then be used to carry any IP
traffic, for example interactive game sessions or push to talk
communication.
-
Nortel's IMS system is likely to be a key piece of Microsoft's plans. It enables a subscriber to launch a video conference during a voice conversation, or access a personalized Video-on-Demand service subscription not just from their home TV, but online from a laptop, a hotel room or from a mobile phone.
- Ericsson's IMS system
says it enables communication through various media, adapted to each
individual's preference and provides a consistent experience across
multiple access technologies.
- Lucent's IP Multi-Media Subsystem
supports IP to IP session over wireline IP, 802.11, 802.15, CDMA,
packet data along with GSM/EDGE/UMTS and other packet data
applications.
- Hewlett-Packard has a a multimedia service to help carriers provide "triple-play" services of voice, video and data.
Control of the IP Multimedia Subsystem could become an thory issue. Consumers want "open" systems while cellular and cable operators prefer a closed "walled garden" approach.
Verizon, Cisco, Lucent, Motorola, Nortel and Qualcomm have collaborated over the last year to create A-IMS (Advances to IMS), meant to provide a foundation for the roll-out of both SIP- and non-SIP-based services in future networks, according to the companies.
The Sprint/Cable wireless partnership may have lots of tricky issues to resolve.

The Weekly Show

drawing from extrastruggle.
We've been having a back channel conversation amongst the trackers at unmediated about how/whether to update the way in which we aggregate, present, and make useable the content on the site, in light of all the various aggregators, digg and its clones, and role model group blog sites that we all consume/use/hate/love. Since we all primarily support open media movements and the freedom of bits and so forth, and with all of us being busy with our primary projects, we are looking for ways to make getting content on the site easier and more streamlined, while making it obvious that we are presenting other sources content. With the availability of open API's for just about any type of media aggegration literally getting past the saturation point, and mashups taking every possible form, we are wondering, is it time to take a step back, or a step forward with how/what we do at umediated? In the course of my surfing today, i found this new site, Boxxet Which just might be the straw that breaks the camel's back in how we all perceive the current mix and match nature of the web as it now stands. What's different about Boxxet from other aggregators and mashups like the newest entry popurls, (which aggregates digg, slashdot, reddit, newsvine, tailrank, and flickr) is that Boxxet is a Website generator. Thats right, just pop in all the urls u want to aggregate (and WHAT from them) choose how u want to format it, plug in the url that u want it to be accessed at... and whammo: Your own site with everyone elses content, and all thats left to do is decide whether googleplex or yahooza is going to be the source of your linklove revenue. And if u have on older domain that u plug this into...well, we all know how the pageranking with search engines work by now. It used to be that u had to have a bit of code knowledge to make all this stuff work. Eyebeam's Re-blog engine which powers this site was not a simple undertaking at the time that Michael Frumin and Michael Migurski put it all together... a half a year before Marc Broadband-mechanicked the term Reblog as his latest buzzword before casting his attention on the ourmedia-meme. (kudo's, kudo's) But now, with the cut and paste mentality of webculture that we at unmediated have helped create, the pace at which people are remixing and repurposing code is accelerating at a rate similar to the curve that we saw with pro-sumer desktop video... almost anyone can do it. I have this sinking feeling in my gut that we will arrive sooner than later at the same existential threshold that the film studios and record labels are squirming under to our joyful cries of "die, dinosaurs, die!". What i am wondering, is how long until my hero of the open-information movement, Cory Doctorow, and the rest of our pals at BB will tolerate re-aggregation and repurposing of his content, (now that he is investing so much more time at the site) before he (or any of one us) screams, "FOUL!" Stewart Butterfield over at Flickr is dealing with this beast at the moment...and i have to admire the dryness with which he states, "I loaded the FlickrCentral pool and firefox got up to using 240mb of ram before dying. So that's not a great user experience, but it's really terrible for Flickr. If it catches on and you don't limit it, we'll have to cut you off :\" Sure, Stewart, blame it on the user experience and firefox. ;) I admire your candor, and personal attention/approach to what has become one of the hottest new BRANDS in Web 2.0 ...that u still have time to be personal and all flickr-fuzzy even after being acquired, but I am sure that your jeans feel like they're fitting a bit tighter all of a sudden. Pretty soon, I expect, a lot of us bell-bottomed infornistas are going to wake up in a similar pair of Jordaches. I'm curious which of us will cut the inseams and sew in another totally different material to keep our style,and which of us will claim that now that we're wearing skintight jeans ("they're really really comfortable...REALLY! You think i should get a pair of Reeboks to go with 'em?"), that the manufacture of bell-bottoms should be forbidden. I point this all out in good humour only to illustrate a point: The times, they are('nt) a changin'>, and Cory just might wake up one day soon in his magic kingdom, and say "Hey, man, where'd all my whuffie go? And he's going to have no choice but to join Walt's pinstripesuits in pushing for copyright extension. It's a pill i hope he (and we) never have to swallow. So i pose the question to our community readers: How do you see unmediated-Are we crossing the boundaries in how we repurpose content? Would you like to see more editorializing? Narrower/Broader scope? Are we a repository of information that you come back to use, or just part of your daily information addiction? Let us know... I, for one, would like to have an idea about what pair of jeans to wear this year ;) michael
