Integration of Session Border Controllers and Diameter Signaling Technology Provides the Security and Quality-of-Service Required by Operators to Deliver LTE Roaming and Voice over LTE Services

Key Takeaways:

  • Sonus and F5 Networks partner to deliver integrated solutions based on best-of-breed SIP and Diameter signaling management solutions
  • The partnership addresses needs of the growing numbers of operators who are deploying LTE and IMS networks and IPX carriers offering roaming across them
  • The solution, available now through Sonus, enables Service Providers to combine the Sonus 5000 series of Session Border Controllers (SBCs) with the F5® Traffix™ Signaling Delivery Controller™ (SDC™) to combine session and Diameter signaling control capabilities, allowing mobile operators to rapidly provide services and service entitlements to users as they roam across LTE and 3G networks
  • The joint Sonus/F5 solution simplifies Service Providers' ability to deliver and monetize mobile Unified Communication (UC) and multi-media services accessed with smart mobile devices

WESTFORD, Mass.--(BUSINESS WIRE)-- Sonus Networks, Inc. (NAS: SONS) , a global leader in SIP communications, today announced it has partnered with F5 Networks (NAS: FFIV) , the industry's leader in Diameter signaling technology, to deliver integrated solutions designed to simplify the way Service Providers deliver differentiated mobile UC and multi-media experiences across blended network environments.

Operators are constructing 4G networks based on LTE and IMS technologies in support of the growing number of smartphones and devices that require 'always on' accessibility to mobile broadband and applications. The combination of capabilities from the Sonus SIP-based Session Border Controller (SBC) and the Diameter-based F5® Traffix™ Signaling Delivery Controller™ (SDC™) enables the delivery of these services in a scalable, billable, secure manner across networks. Service delivery and metering can now transcend network and operator boundaries, and go across network types such as LTE-to-3G. Additionally, operators are able to retain their existing 3G assets, while adding LTE and IMS elements to offer faster and better quality mobile broadband services.

The joint solution will enable growth for Service Providers through the deployment and maintenance of high performance LTE networks and while providing the seamless roaming required in the use of broadband mobile networks and smart devices:

  • "Smartphone shipments are expected to grow 32.7% year over year in 2013 reaching 958.8 million units, up from 722.5 million units last year." (Source: IDC press release, June 4, 2013)
  • 72% of enterprises support tablets for business use "driven by the ubiquitous access and increased speeds of 3G and long-term evolution (LTE)/4G." (Source: Nemertes Research Benchmark, The Business Case for Tablets, December 2012)
  • LTE revenue was $2.7 billion in 1Q'13, an increase of 21% quarter-over-quarter and 108% year-over-year according to Infonetics Research. (Source: 2G, 3G, 4G Mobile Infrastructure & Subscribers Market Share & Forecasts, Infonetics, June 2013)
  • In line with the deployment of mobile services such as VoLTE, Infonetics Research found that the top driver of growth in use of Service Providers SBCs is to locate them at the access edge of mobile networks.

"When combining the advanced, robust solutions of F5 Networks and Sonus, operators can remain confident in delivering LTE roaming and VoLTE services that will satisfy customers and generate revenue," said Mallik Tatipamula, vice president of Service Provider Solutions, F5. "We view addressing the requirements to deliver these services as a natural blend of our two product areas. Looking forward we envision other innovative joint scenarios, such as supporting operators to benefit from offering premium OTT services with our SDC gateway to enable real-time billing and charging. Through our partnership with Sonus, customers will benefit from working with the experts in SBCs and Diameter signaling control."

"The industry is becoming increasingly mobile and, behind the scenes, much is being accomplished to keep up with the demands of enterprises and consumers," said Todd A. Abbott, executive vice president, Strategy & Go to Market, Sonus. "As a result of Sonus' close collaboration with F5, the integration of our products will empower operators of 4G/LTE networks to scale their delivery of enhanced services required by always-connected users and to track service usage, independent of end user location or the network to which they are connected."

"While it is early days for LTE and IMS, we are seeing strong positive growth and expect the trend to continue," stated Diane Myers, principal analyst, VoIP, UC, and IMS, Infonetics Research. "The increased use of mobile broadband networks is driving the growth of Diameter signaling within and between operators."

"The integration of F5's Diameter-based products with the Sonus SBC portfolio is logical, as they perform complementary functions to enable flexible service delivery across multiple types of networks," said Zeus Kerravala, founder and principal analyst of ZK Research. "And with complementary go to market models, I foresee a win for Sonus and F5 as they deliver simpler provisioning and reduced OpEx for their customers building out and interfacing to LTE networks."
