Fixed/Mobile Convergence, UMA, and IMS: An Unstrung Reality Check
Interest in IP Multimedia Subsystem (IMS) technology has exploded in the past 18 months, with the architecture linked to everything from fixed/mobile convergence, rich-media combinational services, and wireline VOIP.

But IMS has been on the roadmap at large mobile operators for several years now just without the kind of public attention that now sees CEOs and CTOs at major operators feel compelled to articulate their "IMS strategies" in formal forums such as earnings calls, analyst briefings, and media appearances.

This report examines an stepwise approach to IMS implementation in mobile core networks, across the transport, control, and services layers. It includes analysis of the positions of major vendors in the IMS systems market, with data on contract awards and operator deployment schedules.

In addition, the report profiles the privately-held vendors that, arguably, offer operators a faster and cleaner path for converging their fixed and mobile networks. As convergence takes off, several of these approaches have been adopted by Tier 1 vendors looking to fill out gaps in their "pre-IMS" portfolios.
Sample research data from the report is shown in the excerpts below:

"Convergence" is happening at all levels of the mobile network, including the move to IP transmission; the introduction of alternative IP-based access networks; the implementation of a distinct control layer; and the introduction of a common service delivery layer. The diagram below highlights the broad convergence trends in the mobile landscape.

An IMS contract should, typically, include at least two out of the following three components: a home subscriber server (HSS), a call session control function (CSCF), and an application server. The chart below shows a total of 19 commercial contracts for IMS systems over the past year (vendor names removed).
