IP Multimedia Subsystem
IP Multimedia Subsystem - Wikipedia, the free encyclopedia. This is an area of great innovation right now. It is a little confusing what folks are doing. Wikipedia give a good over view of what it is.
It's a good overview, basically IMS puts IP networking into a carrier network. You can for instance have a Wifi phone talk peer-to-peer with a GSM phone for instance. They do billing for instance as well.
The entire telecom infrastructure is converging on this. Nice thing about the web is that everyone puts their slides up now. So here are what the big players are doing. There is also IMS for Dummies you can get from Amazon for more depth:
Comments
IMS is the carrier's only hope to be relevant in a world where other than voice, they have no "application" to control. with bulk data plans catching on and MVNO model also coming on strong, the application folks (think amazon, google, yahoo, ebay) hold all the cards in this round. "intelligence" needs to reside on the application-side, not the network. we have been hostage to PSTN-taxes for way too long - time to move the networks to be 'dumb pipes' with network-smart apps running over them (e.g. google should/could know how to get to my multi-band phone via t-mobile wimax or cingular-bulk-data or a local wifi hotspot at starbux).
