Evolving Next-Generation Architecture for Mobile Networks

Industry Tasks Force Announces A-IMSVerizon, along with a group of major telecom industry suppliers, including Cisco, Lucent, Motorola, Nortel and Qualcomm took an important step forward to advance next-generation network architecture for wireless mobile telecommunications networks. The group announced an initiaitve to develop enhancements to an emerging architecture, IMS (IP Multimedia Subsystem).The new architecture, called A-IMS, for Advances to IMS, provides solutions to implement next-generation services in current networks, and creates a foundation for the 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.Dick Lynch, Executive Vice President and Chief Technical Officer at Verizon Wireless, said more work was needed.”We applaud the visionaries who have done a great job developing IMS over the last few years,” Lynch said. “But as we approached implementation planning, it became apparent that there are some practical, real-world issues that need to be addressed if we are to transparently and completely deploy and maximize the use of this new architecture. To us, it is also important that it be built to support the bridging of the present non-IP reality as we transition to the future. As people look at what our task force has accomplished, I expect that they will see significant benefits, including embedding VoIP hooks into the lower levels of the stack and addressing security issues in a more systemic way. These are exciting advancements that are headed rapidly into our mainstream technology roadmap.”The group’s task force has developed a concept document and an architecture document that are being provided to industry leaders. The task force plans to make standards contributions in the near future.”The promise of IMS is extraordinary, for wireless service providers, as well as for all network providers,” said Charlie Giancarlo, Chief Development Officer, Cisco. “A-IMS enhances the opportunity for success for not only the network providers but also for companies in technology, infrastructure, handset manufacturing and service design and, most importantly, for the consumer.”Andrew Seybold, of the Andrew Seybold Group, endorsed the initiative. “I plan to actively support the adoption of A-IMS as a set of enhancements to IMS and MMD,” he wrote in Outlook 4Mobility. “I believe that the wired and wireless communities will also recognize the value of A-IMS and I encourage them support its adoption. Verizon and its vendors have identified problems and provided solutions in a manner that will result in an even better IP experience for all with multiple vendor solutions and a truly open set of standards.”
