Verizon, together with key telecom industry suppliers, has announced a vision for the advancement of next-generation network architecture for wireless mobile telecommunications networks. Dick Lynch, Executive Vice President and Chief Technical Officer at Verizon Wireless, said the company has been working for nearly a year with a task force of the industry's "best and brightest" network engineers and strategists from Cisco, Lucent Technologies, Motorola, Nortel and Qualcomm. Their goal has been to develop enhancements to a well known, emerging architecture, known as IMS (IP Multi-media Subsystem).
The multi-vendor team has generically termed this architecture A-IMS - for Advances to IMS -- in order to reflect its evolution from work done earlier in technology standards bodies.
The A-IMS architecture developed by the task force provides solutions to implement next-generation services in current networks, as well as creates a foundation for the efficient roll-out of both SIP- and non-SIP-based services in future networks.
IMS is generally accepted as a core component of virtually all next-generation, IP-based communications networks for SIP-based applications, and is designed to assure standardization of multi-media services across all of these interconnected networks.
Analysts at Ovum commented "Verizon Wireless' deployment of CDMA2000 1XEV-DO Revision 0 in October 2003 has kick-started 3G deployments in the US market, putting pressure on Cingular and Sprint Nextel to follow suit. Unlike its EV-DO announcement, Verizon Wireless is not the first tier 1 mobile operator in the US market to embrace IMS architecture: Sprint Nextel and Cingular made their announcements before Verizon Wireless. However, Verizon Wireless' approach clearly has more of a carriers' view on how the industry should implement the IMS architecture. A-IMS places emphasis not only on SIP-based applications but also on non-SIP-based applications."
