Network convergence, the rise of content distribution networks and the consolidation of service hosting enabled by the cloud-computing model are significantly altering traffic patterns being observed by service providers. These developments, along with changes in the business environment, are driving the choices for technology.

WebRTC: enhancing the web with real-time communication capabilities

April 5, 2012

WebRTC: enhancing the web with real-time communication capabilities Technical, sociocultural, local and global changes in ICT can happen overnight. People adopt new solutions instantly, with cutting-edge technologies rapidly becoming mainstream. HTML5 is a clear example of how change, driven by a combination of factors, creates something new and is itself a catalyst for more innovation. Support for enabling real-time communication (RTC) on the web – WebRTC – is gaining momentum.

Validating voice over LTE end-to-end

February 23, 2012

Validating voice over LTE end-to-end Unlike previous 3GPP wireless technologies, LTE has no circuit-switched bearer to support voice, so carrying voice over LTE requires a migration to a voice over IP (VoIP) solution – commonly under the umbrella of IMS. Until this migration occurs, LTE-capable handsets need to revert to 2G or 3G for voice calls: an approach that is not ideal in the long term. Driven by major operators, the voice over LTE (VoLTE) ecosystem is maturing rapidly and tracking well to target commercial timelines.

Wi-Fi integration – Easing hotspot issues

Wi-Fi integration – Easing hotspot issues People want to be able to use their smartphones, laptops, tablets and other devices everywhere, and so they need access to 3G, 4G and Wi-Fi. Now that mobile broadband and mobile multimedia services are so popular, subscribers are beginning to expect broadband access to be available wherever they go – not just at home or in the office. People want to be able to connect from their cars, on the train, in aircraft, from remote locations, in the urban jungle and even from areas where it is difficult to provide access, such as in mines, tough terrain or subway tunnels.

Adding value to IMS multimedia telephony

December 31, 2011

Service quality – managing the user experience How service developers can focus on adding new value to IMS telephony for both users and operators – without having to apply basic SIP. Multimedia communication networks based on IMS and standards for multimedia telephony (MMTel) provide support for voice-over-LTE (VoLTE) and a basic set of telephony services. The combination of IMS and multimedia telephony (MMTel) make multimedia functions possible, so that users can add or remove services and callers during an ongoing communication session – a user can start a communication session with messaging, complement it with voice or video, add or remove participants, send files, share pictures and more.
