IMS in the Spotlight

10:00 AM -- After years of hype, there are signs that the IP Multimedia Subsystem (IMS) concept is becoming a real part of carriers' day-to-day operations. (See What's Up With IMS?)

Swisscom AG (NYSE: SCM) has just announced that it will launch an IMS-based converged service starting next month and that it will roll out multiple new integrated services during the next few years. "Swisscom is one of the first telecoms providers in Europe to start the gradual changeover to this pioneering technology," it boasts in its press release. (See Swisscom Trials IMS.)

The news will no doubt please Ericsson AB (Nasdaq: ERIC), which landed a multiyear IMS deal with the Swiss carrier in early 2007. (See Ericsson Picked by Swisscom.)

Ericsson is also the vendor behind Telenor Group (Nasdaq: TELN)'s plans to introduce unified IMS-based services for enterprise users in Sweden. (See Telenor Does IMS With Ericsson.)

Attitudes to IMS have waivered over the years, with many carriers put off by some of the initial claims that IMS would be a cure-all for operators' service delivery and management needs. Despite this, many carrier CTOs have recognized the potential benefits of IMS, while recognizing it might be some years before the key technologies are mature enough for them to decommission their legacy voice and applications platforms.

Meanwhile, there's no shortage of IMS-related news to keep the bandwagon rolling. (See DT Checks Out Italtel's IMS, TWC Uses NSN for IMS, Cedar Point Blazes IMS Path , Starent Intros Convergence Platform, and Acme Teams for SIP Femtos.)
