IMS is an open, standards-based architecture for next-generation IP-based networks, supporting both mobile and fixed services, and is touted by its supporters as the ultimate goal for carrier networking, casting the Unlicensed Mobile Access technology that underscores BT’s recent Fusion announcement as no more than an interim step along the way.

SIP underscores IMS, which is an implementation of the 3GPP’s SIP standard running on a standard IP network to enable network-controlled multimedia services.

This is where Cardiff-based Ubiquity’s technology comes in, relative to the IMS offering from Nokia. Ubiquity calls its SIP A/S a carrier-class deployment platform and a programmable, standards-based application creation environment that allows customers to develop and deploy next-generation converged communications services.

Ubiquity also helps customers develop these services through its Professional Services Group, with offices in the US, Canada, Japan, and China, as well as the UK. Customers can extend the SIP A/S through a standards-based SIP Servlet API, while the company offers a number of pre-built Application Building Blocks (ABBs) and non-SIP connectors (ABB-Cs) for rapid development without detailed knowledge of SIP.

In parallel with the SIP A/S announcement, Nokia and Ubiquity also announced the creation of a first SIP-enabled multimedia app, Media Push, enabling mobile users to subscribe to news and other types of media or information channels and have content pushed to their terminal.
