Huawei IMS — VoLTE & VoNR Engineering (CloudIMS, ATS, SBC)

End-to-end voice on Huawei networks: CloudIMS CSCF, ATS9900 application server, SE2900 SBC and their interworking with RAN and core for VoLTE, VoNR, EPS fallback and emergency calls — with SIP-level troubleshooting.

Independent training on Huawei technologies by practising engineers. Teleriu is not affiliated with, endorsed by or an authorised partner of Huawei; product names are used only to describe course content.

Course overview

Voice quality is a regulator-monitored KPI across the GCC. This program gives engineers a complete view of how a VoLTE/VoNR call is registered, established and maintained across Huawei IMS, core and RAN, and how to diagnose failures from SIP and Diameter traces.

Covers the practical migration questions operators face today: VoNR readiness, EPS fallback tuning, SRVCC retirement and roaming voice.

Who should attend

  • IMS and voice core engineers
  • Core and RAN engineers involved in voice KPIs
  • Test and integration engineers for VoLTE/VoNR
  • NOC teams handling voice complaints

Prerequisites

  3. 3Configure voice-related QoS, policy and RAN interactions
  4. 4Diagnose VoLTE/VoNR failures from SIP, Diameter and RAN traces
  5. 5Plan VoNR launch and EPS fallback optimisation

Frequently asked questions

No. This is an independent Teleriu program taught by engineers with hands-on Huawei deployment experience. Where a course is aligned to an HCIA/HCIP exam we cover the published exam domains, but the certificate issued is a Teleriu certificate of completion; the Huawei exam is booked separately by the participant.

Live online programs are delivered in real time by an instructor over video with shared labs and interactive Q&A. Classroom programs are delivered face to face in Dubai or other GCC locations, with the instructor and lab environment in the room. Both use the same curricula and instructors.

Programs are built on 3GPP, O-RAN and industry standards and are vendor-agnostic by default. Corporate deliveries can include vendor-specific parameter mapping and scenarios where required.

Participants who complete a program receive a Teleriu certificate of completion. Teleriu programs are professional technical training and are not affiliated with any certification body unless explicitly stated.
