O-RAN Service Models
O-RAN Service Models
BubbleRAN supports all the mandatory fields of KPM v3, RC v1.03 and CCC v3.
KPM
Key Performance Metric is the O-RAN service model for monitoring. As of today, the following variables are supported:

New variables are expected in the near future. More than 900 variables are defined by 3gpp and O-RAN. If you are missing a value, please, do not hesitate and contact the bubbleran team if a concrete variable is needed.
RC
The RAN Control is the O-RAN service model to control the RAN. As of today, handover (connected mode mobility), MCS selection (extending RC 7.6.XXX) and slicing (dedicated PRB Policy Ratio 8.4.3.6) are supported.
CCC
This is the Cell Configuration and Control service model. As of today the bandwidth part manipulation is supported, enhancing the energy saving.
