STL and ASOCS demonstrated “RAN Intelligent controller (RIC) interworking with O-eNB”.
Scope included demonstrating Mobile Load Balancing (MLB) xApps, E2 setup and subscriptions as per O-RAN standards.
The key elements of overall setup include “Near–RT RIC” and “MLB XApps” developed by STL and “O-eNB” developed by ASOCS. The RIC and O-eNB interact through E2 interface which is aligned with the published O-RAN E2 Application Protocol (E2AP) specification v1.0.
The Mobile Load Balancing solution is an xApp of the Near-RT-RIC, which is used to achieve optimal traffic distribution based on desired objectives.
RIC is continuously monitoring the utilization of RAN slice resources and as soon as a cell utilization reaches its threshold, it triggers to shift some of the users to a nearby less busy cells that can accommodate users of the slice with the pre-defined QoS. This entire process is automated and works in near real time to balance the load on cells.
