IP multimedia subsystems deployment continues to grow
The growth of LTE deployments and the scalability of IMS should lead to further expansion of IMS technology.

Designed to fill the gap between traditional telecommunications technology and Internet technology, IMS (IP multimedia subsystem) technology allows service providers and network operators to offer innovative services to their customers. This technology has evolved over the last few years with a reasonably mature standard available currently. It is expected that in the future, the subsystems will likely be deployed in large numbers. Key market drivers for test and monitoring equipment for this technology include the growth of LTE (long term evolution) deployments and the scalability of IMS (see chart).

The capability of IMS to deliver faster transmission of voice and data, including standard calling features like caller ID, click-to-call, and messaging, as well as a whole gamut of enriching services like voice and video for TV-screen delivery, access to call history, and click-to-call from the IPTV remote, at much cheaper rates, will likely ensure more deployment of the technology in the future. IMS provides scalability, flexibility, and ease of use for service providers and network operators. IMS deployment has moved from projects that were mostly experimental and small scale to more realistic deployments that must ensure QoE (Quality of Experience) and QoS (Quality of Service) for consumers. The technology now focuses more on the access side of both wireline and wireless networks.
IMS offers a scalable architecture that enables the gradual build up of networks. Such scalability augurs well for the deployment of this service-enriching technology during the current economic situation. The deployment may face some resistance as service providers and network operators put a freeze on capital expenditure, but because they face the challenge of ensuring higher average revenues per user, it makes sense to gradually build a scalable and flexible setup that can ultimately yield a complete deployment of IMS. Moving from 2010 onward, when service providers feel that they are unable to manage their services with legacy networks, IMS deployment will likely grow.

Another important driver, the scheduled LTE deployment, will likely happen in 2010 with larger versions to follow a couple of years later. LTE’s support for IP-based traffic with end-to-end QoS supports IMS well. From the network equipment manufacturer’s viewpoint, IMS is considered a foundation for LTE deployment, and these manufacturers have supported the technology throughout its evolution. Alcatel-Lucent, Nokia Siemens, Verizon, and others are currently capable of offering infrastructure for IP converged applications and services on their wireless and landline broadband networks. LTE will remain one of the key wireless access networks linked to the IMS technology.
The overall picture in the IMS test and monitoring market, even under a strained economy, depends on the capabilities of the technology. The IMS test and monitoring market, though crowded, remains very competitive with a very high potential for growth.
