Disruptive Analysis’ report, “The evolution of
SIP- and IMS-capable mobile handsets” is the most comprehensive review
of the market for next-generation IP-connected cellphones, offering detailed
analysis and recommendations.
The noise level around IMS is huge. But up until now, almost all attention
has been focused on IMS network deployments and SIP applications. The phone
itself - the "User Equipment" in IMS industry jargon - has almost been
ignored. Once again, the telecom industry seems to have under-estimated the
complexity of getting the phones "right" before investing billions on new
infrastructure. Not only that, but the gap is likely to be filled by "open"
or "naked" SIP-enabled mobile phones, which will enable 3rd-party providers
- such as Internet VoIP and IM specialists - to exploit a huge mobile user
base with their own on-handset software applications.
This ground-breaking study provides extensive argument and
rich quantitative forecasts of the future of IMS- and SIP-enabled mobile
phones. It assesses operator and "disruptive" usage cases, looks at a wide
range of handset types and software architectures, and considers practical
issues around standards, user experience and integration. It profiles the
leading suppliers of IMS and SIP handset software.
The market size and segmentation data covers handset type (eg smartphone vs
featurephone), SIP/IMS implementation (eg "Naked SIP", "Closed IMS" etc.),
regional market sizes and wireless bearers (cellular, WiFi, UMTS, CDMA,
Based on a huge research effort spanning 300+ interviews
and meetings with
key providers of handsets, software, network services, semiconductors,
operator infrastructure and corporate networks, the study provides
actionable, substantiated insights into the "End User Battleground" for SIP
and IMS services - the handset itself.
many operators are deploying IMS networks now, it is highly likely that
IMS phones will be late-to-market, and suffer from poor user experience.

standards are too protocol-focused and are insufficient to define how IMS

operators will attempt to block “parasitic” 3rd-party SIP
applications, by “locking” handsets or intercepting network traffic. These
attempts will seem clumsy and vindictive, and will likely drive churn and
operators’ visions of stopping threats from Internet-based brands, 3rd-party
VoIP and other services, by locking-down IMS networks and only permitting
customers to access IMS-based services, are totally unrealistic.
number of specialist firms are emerging to supply SIP and IMS software for
mobile phones. However, many will struggle with integration of their
clients into existing OS and application software on handsets.
