UCN

In the era of digital transformation, to help enterprises develop and improve information-based communications, Huawei innovatively launches the new-generation Unified Communication Node (UCN) solution. Based on completely independent and controllable software and hardware technologies, Huawei provides small-sized and highly reliable voice core network solutions for customers. The UCN provides access capabilities of soft and hard terminals, PBXs, and IADs for enterprise fixed voice services. It also provides VoLTE/VoNR voice and video call capabilities for 4G/5G mobile voice services, meeting customers' increasing communication requirements in the 5G interconnection era.
Highly integrated and miniaturized IMS

Highly integrated and miniaturized IMS

• High-performance hardware platform: implements switching-free networking and simplifies the network
• Switching-free and disk array-free: The UCN does not require dedicated management nodes. Centralized deployment of the forwarding plane to maximize port efficiency

Carrier-class reliability

Carrier-class reliability

• Network overload protection: When the network is overloaded three times, the traffic is not lost and the service unit is not affected
• Hot backup of dual-system user data: No call drop occurs in dual-site switchover and upgrade scenarios

Efficient security protection

Efficient security protection

• IDS, CAC, network isolation
• Service encryption
• blocklist and trustlist

Easy deployment and installation

Easy deployment and installation

• Out-of-the-box use, reducing deployment parameters by 80% compared with the carrier's large-network IMS network
