Ericsson is leading the IMS market.
Infonetics Research said Ericsson continues to be the
leading IMS vendor in terms of equipment installed by respondent operators.
Huawei is a real standout in this year’s survey,
growing its installed base every year among survey respondents and topping the
vendor leadership list for pricing, total cost of ownership, product roadmap,
financial stability, and reliability.
“For the first time ever, LTE is the top driver
for IMS deployments in our annual IMS service provider survey. But while LTE
may be the number-one driver, the reality is the majority of services running
over IMS today are fixed-line VoIP. None of our survey respondents has yet
deployed voice over LTE (VoLTE),” said Diane Myers, principal analyst for VoIP
and IMS at Infonetics Research.
The longer-term inevitability of an all-IP mobile network is
leading operators to IMS for other services first, even if VoLTE services are
farther down the road.
IMS networks continue to be deployed by fixed-line
operators, mobile operators, and cable operators; 71 percent of Infonetics’
survey respondents have already deployed IMS and the rest are in the process of
deploying IMS.
Fixed-line VoIP service is the mainstay of IMS deployments,
with 76 percent of respondents running residential voice over broadband, SIP
trunking, or hosted business VoIP over IMS today, growing to 100 percent by
2014.
Mobile services are growing in importance: by 2014, 71
percent of respondent operators plan to offer RCS/e, more than half plan
to offer VoLTE, and more or less a third will offer VoIP over 3G and mobile
messaging.
