Brown also works on the Telecoms &amp; Internet converged Services &amp; Protocols for Advanced Networks (<a href=\"http:\/\/portal.etsi.org\/portal_common\/home.asp?tbkey1=TISPAN\"><span style=\"COLOR: windowtext; TEXT-DECORATION: none; text-underline: none\">TISPAN<\/span><\/a>) group, a standardization body of European Telecommunications Standards Institute (ETSI). TISPAN incorporates elements of 3GPP IMS in its next-generation network architecture. The organization focuses on fixed networks and convergence with the goal of promoting a subsystem-oriented architecture in which network resources, applications and user equipment are standards based and common to all subsystems.<\/p>\n<p>The resulting article is an excellent primer on IMS, why IMS is needed and where it fits from a social and technical perspective.<\/p>\n<p>&quot;One of the big problems is that there are two sets of history coming at the marketplace,&quot; said Brown. &quot;On the PC side everything is new and there aren&#8217;t a lot of user expectations for new product concepts. The other dynamic is that we&#8217;ve had voice and phone communications for over 100 years and there are social, end user, governmental and regulatory expectations.&quot; Brown said combining devices and services is one challenge, but converging two very different attitudes toward delivering products may be an even bigger challenge. That&#8217;s where groups like 3GPP and TISPAN come in, trying to build a bridge between people and attitudes, as well as networking environments.<\/p>\n<p>The modular standards embodied in IMS <span style=\"COLOR: #1d0128\">enables easy interoperability of products and services from both the circuit and packet-switched worlds.
