The analyst firm warned, however, that operators will have to develop long-term plans for implementation because of the inherent risks involved in deploying "unproven technologies".
Vendors are pushing the potential to offer services such as push-to-talk, mobile VoIP, video sharing and instant voice messaging.
"The examples currently being proposed do not in themselves provide strong justification for IPMS deployment,” said report co-author Dr Alistair Brydon.
"Many services are relatively weak or unproven, and in some cases proprietary solutions may be better."
But the report stressed that in the longer term operators will find that IPMS offers a better way of providing a wide range of mobile services flexibly and cheaply, and that the technology will help operators compete strongly with fixed line services.
Analysys claimed that early users include BT, France Telecom and Sprint in the US. But the firm concluded that, although IPMS could be used to help converge fixed and mobile networks, "network convergence is unlikely within five years".
