IMS

The world’s most experienced IMS partner

Ericsson has, to date, delivered 64 IMS networks into commercial operation, establishing itself as the world’s most-experienced IMS partner. Many of these projects involved rapid transformation of large networks. With this kind of intensive practical experience, Ericsson can offer operators a safer investment in IMS, due to shorter implementation times, reduced risk and global best-practices sharing.

The world’s most reliable IMS system

Since 2005, when Ericsson launched the world’s first commercial IMS network, we have completed close to 20 large-scale deployments, with networks serving anything from several hundred thousand users up to 6 million.

More than 650 Ericsson IMS nodes are in commercial live-service, which makes our IMS system the world’s most field-proven. Node and network level redundancy, coupled with the unique Dynamic Subscriber Allocation functionality, ensures 99.999 percent availability. The M+N architecture ensures cost efficiency and high scalability.

Solutions for revenue growth and opex reduction

We offer solutions for revenue growth and opex reduction:

• Evolving mobile telephony to full voice over LTE with enhancements of multimedia communication. Securing the voice business in LTE and delivering seamless services to any access.
• Evolving broadband communication by launching new services cost-efficiently for families and individuals. Leveraging convergence and creating bundles to reduce churn and increase revenues.
• Transforming PSTN networks with Ericsson IMS, which enables lower costs for first-line services and builds a foundation for top-line growth.
• Capturing the enterprise communication opportunity with unified communication and network-based HD video-conferencing services, based on the converged IMS network.

Grow economically with superior capacity and reusable hardware

Ericsson IMS nodes boast the highest capacity on the market, considering the functions needed in a normal traffic situation. Their capacity efficiency decreases energy consumption, floor space and the number of nodes which must be operated and managed.

All Ericsson control nodes run on the same Ericsson Blade System, and the media plane functions are uniquely combined in the Ericsson Media Resource System. Common hardware allows operators to co-locate different nodes in a cabinet, minimize spare-part investment and reuse hardware in different nodes, based on varying capacity needs.

The very same system is used for fixed and mobile networks, which ensures convergence and further minimizes network complexity.

Our complete offering

Realizing the potential of IMS requires planning and a structured approach to implementation. In addition to the pre-integrated network system, our offering includes Consulting, System Integration, Managed Services, Network Deployment and Integration, and Education and Support Services. It also ensures that the applications have the interoperability, quality of service and security needed to ensure mass market take-up.
