IMS Redux

In the telecom industry the difference between the hype of new technology and actual implementation of solution sets, that includes that technology, is anything but rational thinking. As a long time colleague of mine used to say, “between vision and reality there lives hallucination”.

IP-Multimedia Subsystem (IMS) started out as the brainchild of the 3rd Generation Partnership Project (3GPP), which incidentally is celebrating its tenth anniversary as a specifications body—a rather long time given the turbulent world of mobile telecom. IMS was part of its Release 5 specification, back in mid-2003, and further revised in Releases 6 & 7. While there is nothing wrong with the basic premise of IMS, there is a world of hard work in going from the concept to the reality of service delivery.

As some of you who follow my scribbling might recall in the past I wrote about the need for common catalogs. A recent whitepaper co-authored by Chun-Ling Woon and Bill Otto released by Pipeline Publishing converges on the topic of IMS and its dependence upon product/service/network catalogs. I’m a big fan of knowing what you have and catalogs are one important way to get there. If you are flummoxed by the conflicting and confusing aspects of IMS you might want to read their paper.

Chun-Ling Woon is VP of marketing and business development at ConceptWave, while Bill Otto is CTO at TierOne both are companies that Shulist Group has worked with.
