* No strong case for short-term IMS deployment to support services such as
push-to-talk and video sharing

* IMS will be widely deployed by mobile operators within five years,
enabling faster and more efficient service delivery and helping to
accelerate fixed­mobile substitution

* IMS enables service and network convergence, but adoption will be
constrained by commercial, technical and regulatory issues


CAMBRIDGE, UK, 27 July 2005 ­ IMS (the Internet Protocol Multimedia
Subsystem), the latest so-called “must have” technology for telecom
operators, will be widely adopted within the mobile operator community
within five years, according to a new report, Delivering Strategic Benefits
with IP Multimedia Subsystem(IMS), published by Analysys, the global
advisers on telecoms, IT and media (http://research.analysys.com).


IMS is an open, standardised, relatively easily deployed network
architecture that enables more flexible control and billing of multimedia
services delivered by IP networks using SIP (Session Initiation Protocol).
Shrouded in technical complexity and hype, IMS is being heavily promoted by
vendors as the “next big thing” for both fixed and mobile operators,
promising diverse service opportunities and cost benefits.


According to the Analysys report, while vendors of IMS are eager to point to
the immediate service opportunities to justify its short-term deployment,
the examples currently proposed do not, in themselves, provide strong
justification for IMS deployment. Consequently, warns Analysys, operators
should avoid being distracted from their core revenue opportunities in voice
and messaging into making rushed decisions about implementing IMS in order
to launch as yet unproven services such as push-to-talk, mobile VoIP, video
sharing, IP Centrex and instant voice messaging.


“Many services are relatively weak or unproven, and in some cases
proprietary solutions may provide quicker, cheaper or better-tested
alternatives,” says co-author Dr Alastair Brydon. The report cites a number
of weaknesses in short-term services enabled by IMS, including uncertain
demand, risk of revenue cannibalisation, quality of service, interworking
and handset availability. “Operators should maintain their focus on the most
attractive service opportunities, not just those enabled by IMS,” says Brydon.


The report is more upbeat on the prospects for IMS in the slightly longer
term. “IMS presents operators with valuable capabilities to support enhanced
services, and service and network convergence,” says co-author Dr Mark Heath.


For mobile operators there is a strong, longer-term business case for
deploying IMS in order to support a wide range of mobile services flexibly
and cost effectively. “IMS will enable enhancements to basic 3G
circuit-switched voice services, such as presence information, advanced
voice and text messaging capabilities and improved ease of use. These will
help to position mobile voice services as significantly superior to PSTN
(public switched telephone network) services, to accelerate fixed­mobile
substitution,” says Heath.


IMS can also support service convergence, with a common set of services
across fixed and mobile networks, and network convergence, providing cost
savings with a single core IP network. “While we see a number of early
movers, such as BT, France Telecom and Sprint, widespread service and
network convergence is unlikely within five years,” says Heath. “Complex
technical, commercial and regulatory issues need to be addressed and early
movers may need significant customised developments.”


The new report studies specific mobile, fixed and converged services
proposed by IMS vendors, assessing their market potential and barriers. It
also considers the role of IMS in supporting strategic initiatives, such as
fixed­mobile substitution, converged broadband-to-mobile services and
integrated all-IP networks. The report provides specific recommendations to
network operators, to guide their decisions on IMS deployment, and to
equipment vendors, to strengthen their propositions.
