Fraunhofer IIS and Nokia have completed the first interoperable Immersive Voice and Audio Services call over a live 5G IMS network.<\/em><\/p>\n\n\n\n

Fraunhofer IIS and Nokia have made a breakthrough in next-generation voice services with the first interoperable Immersive Voice and Audio Services live call over Nokia\u2019s 5G IMS network.<\/p>\n\n\n\n

This milestone was achieved by participants from Fraunhofer IIS and Nokia during the recent 3GPP SA4 meeting in Dallas, demonstrating that immersive audio communication is ready for real-world deployment.<\/p>\n\n\n\n

“This is a significant achievement that brings immersive voice communication closer to reality. It signals to mobile network operators, implementers and other industry stakeholders that IVAS is ready for deployment and opens up new possibilities that could transform everyday telephony into more realistic experiences as the industry moves towards 5G Advanced and 6G,” said Manfred Lutzky, Head of the Audio for Communications Department, Fraunhofer IIS.<\/p>\n\n\n\n

The test involved Nokia\u2019s IMS network and two different client setups, each using distinct immersive audio capture methods and IVAS coding formats. Despite these differences, the call worked seamlessly.<\/p>\n\n\n\n

This demonstration highlights interoperability at its best and shows how global standards can turn innovation into practical solutions for the telecommunications industry.<\/p>\n\n\n\n

\u201cThis interoperable IVAS call over Nokia\u2019s 5G IMS network marks a major milestone towards everyday immersive audio communications. It follows the world\u2019s first IVAS call which Nokia made last year.<\/p>\n\n\n\n

The test showcased seamless interoperability between different spatial audio formats – including Metadata-Assisted Spatial Audio and Ambisonics – proving live immersive cellular calls are nearer to industry adoption. We\u2019re pleased to partner with Fraunhofer and invite widespread industry collaboration to bring IVAS standardized audio experiences to life – because in audio technology, hearing is believing,\u201d said Jyri Huopaniemi, Head of Audio Research at Nokia.<\/p>\n\n\n\n

Immersive Voice and Audio Services, known as IVAS, is the new mandatory voice codec defined in 3GPP Release 18, the global standard that ensures technologies work across networks and devices worldwide.<\/p>\n\n\n\n

IVAS enables spatial audio transmission over 5G with low latency and supports formats ranging from mono and stereo to multi-channel, Ambisonics and object-based audio.<\/p>\n\n\n\n

In practical terms, IVAS transforms calls from simple voice exchanges into rich three-dimensional sound experiences, opening the door to new use cases such as advanced conferencing, remote assistance and extended reality applications.<\/p>\n\n\n\n

The achievement is the result of close collaboration among leading technology companies, including Fraunhofer IIS and Nokia, working together under the 3GPP standardisation process to make immersive communication a reality and accelerate industry adoption.<\/p>\n\n\n\n
