Making IMS More Resilient and Reliable Today

For the last few years, the IP Multimedia Subsystems (IMS) architecture has been heavily discussed by leading service providers and their suppliers but not rapidly implemented due to fragile interoperability and untested specifications.  Both barriers, expected during initial development, appear to be quickly falling as the technology with more production deployments.  This week at CableLabs, Mu is working with its MSO clients to help speed IMS deployment of advanced IP services.

Another solid point of IMS engagement occurs regularly at the IMS Forum’s Plugfest at UNH IOL.  Many IMS ecosystem members participate to ensure both product interoperability and testing of availability/resiliency before deployment in production Carrier networks.  The IMS Forum and Mu also just published a new paper describing the importance of IMS Availability and Resiliency testing prior to product deployment – including the proactive elimination of product weaknesses and 0day issues.  Interoperability was the IMS Forum’s starting point  but always-available IMS-based services are essential to carrier profitability and vendor success.

Similarly, mobile operators in the US and Europe at this week’s Mobile World Congress Conference including Verizon and AT&T are moving beyond specs and noticing the revenue implications of advanced IMS applications and mobility services.  In the United States, AT&T is gearing up their IMS-based applications.  AT&T is rolling out VoIP over IMS through its U-verse (SM) VoIP offering. 

Nokia last week rallied a group of key IMS-interested operators, infrastructure and device vendors comprised of Orange, Telecom Italia, Telefónica, TeliaSonera, Ericsson, Nokia Siemens Networks, Nokia, Sony Ericsson and Samsung, towards IMS services calling them “rich communication” applications.  Naming doesn’t matter much since both carriers and their vendors realize the revenue opportunity associated with their respective IMS ecosystems and the maturing IMS standards.  This holds true for extending traditional GSM standards over IP as defined by the 3GPP group and in enhancing existing services (voice, now over IP as well as GSM) for ultimately offering new services, to drive real-time application usage and associated revenue.
