Deutsche Telekom partnered with Juniper Networks, AirHope, VMware and Viavi for this multi-vendor trial
German service Deutsche Telekom introduced technical particulars of a multi-vendor trial round programmable radio entry networks that demonstrates the potential of the non-real-time RIC and rApp idea to automate and optimize disaggregated RAN.
The telco mentioned that this trial is a part of the telco’s dedication to the event of Open RAN (O-RAN) know-how.
The service mentioned that non-RT RIC brings agility, and programmability to disaggregated radio entry networks and permits third-party purposes (rApps) that may carry out closed-loop automation and optimization of RAN components and assets.
Deutsche Telekocom, along with its companions AirHop, Juniper Networks, Viavi Options and VMware, accomplished a RAN closed-loop optimization proof of idea (PoC) inside Deutsche Telekom’s lab setting in a multi-vendor setup primarily based on ONAP & O-RAN specs.
In the course of the PoC, the companions efficiently executed two use circumstances:
-Bodily Cell Identifier (PCI) optimization targeted on detection and backbone of PCI confusion and collision situations.
-Power Financial savings dynamic Multi-Service administration (ESMC) utilizing a synthetic intelligence and machine studying (AI/ML) mannequin, educated to find out the optimum time to allow/disable sleep-mode on capability cells to be able to save vitality whereas sustaining consumer high quality of expertise (QoE).
Deutsche Telekom famous that preliminary checks had been carried out in an actual end-to-end lab setup utilizing a small O-RAN community to validate end-to-end configuration and efficiency administration (CM & PM) integration for an actual community setting. Most checks had been executed on a extra complicated community setup utilizing an O1 community emulator to validate rApp logic and stress check the RIC parts to benchmark the assorted options, Deutsche Telekom mentioned.
For this trial, Deutsche Telekom supplied a self-developed service administration and orchestration (SMO) framework together with a Non-RT RIC resolution primarily based on the O-RAN SC Non-RT RIC
In the meantime, Juniper Networks and VMware built-in their Non-RT RIC merchandise into the service’s SMO framework, whereas Viavi supplied their RIC tester to emulate the O1 interface.
“With this PoC, we got down to assess the technical integration complexity of the parts delivered by every get together, the extent of customization required, to gauge the maturity of merchandise and to establish potential future standardization necessities,” mentioned Petr Ledl, VP and head of community trials and Integration Lab at Deutsche Telekom.
A RAN Clever Controller (RIC) is a software-defined part of the O-RAN structure that’s chargeable for controlling and optimizing RAN capabilities conduct, Deutsche Telekom defined. The RIC permits quick onboarding of third-party purposes (Apps) that automate and optimize RAN operations at scale.
The non-real-time RIC (Non-RT RIC) is a part of the SMO framework, which is centrally deployed within the service supplier community. In accordance with the German telco, it permits greater-than-one-second management and coverage steerage over the RAN components and their assets via so referred to as rApps.
It additionally permits AI/ML capabilities for the RAN and makes use of long-term community knowledge, reminiscent of efficiency metrics in addition to enrichment knowledge from exterior purposes to coach and generate AI/ML-driven purposes, Deutsche Telekom mentioned.
