Nokia (News - Alert) Solutions and Networks (NSN) announced an enhanced solution optimizing Voice over LTE (VoLTE) network connection quality and control with better bearer switching and shorter delay.
VoLTE is emerging as the preferred solution to support real-time voice traffic in a world where an increasingly number of networks are turning all IP. The LTE (News - Alert) standard is specifically designed to support a significant amount of traffic.
NSN’s enhanced voice call continuity complements VoLTE by enabling seamless handovers to 2G or 3G networks, the company said, allowing operators with selective LTE coverage to deliver VoLTE services.
With VoLTE optimization capabilities, the solution allows for faster and more precise handover, enabling longer use of VoLTE within LTE coverage.
With an aim to help operators ensure better voice and data quality to customers, NSN is also expanding its Service Quality Manager with a VoLTE content pack.
The fact that voice can be carried more efficiently over LTE makes VoLTE services more attractive. NSN has commercialized its enhanced Single Radio Voice Call Continuity (eSRVCC) solution to enable VoLTE offerings across both variants of LTE networks.
Since voice quality is a key differentiator for VoLTE, ensuring top service quality is a high priority. NSN Service Quality Manager (SQM) now features a new VoLTE content pack in order to monitor the VoLTE service in real-time, across multi-technology, multi-vendor networks.
SQM is designed to correlate network events to provide one view, through which operators can see all relevant information at a glance, helping them identify faults 70 percent sooner and resolving them 20 percent faster, the company said.
NSN is well placed in the VoLTE arena with 12 commercial contracts and IMS deployment in one of the world’s largest live LTE networks, the company said. With IMS core and Telephony Application Server (TAS) core offering seamless integration to existing 2G or 3G core networks, NSN aims to provide full VoLTE functionality.
“Once subscribers get a taste of high-speed data, ultra fast call set-up times and HD-voice quality of 4G LTE networks, they’re keen to stay on 4G wherever they can,” said Michael Clever, vice president, Voice and IP Transformation at NSN. “We have implemented enhanced SRVCC functionality as a software upgrade on top of our existing IMS/VoLTE core, further simplifying network deployments.”
