LOAD ESTIMATION AND BALANCING IN VIRTUALIZED RADIO ACCESS NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827681 titled 'LOAD ESTIMATION AND BALANCING IN VIRTUALIZED RADIO ACCESS NETWORKS

Simplified Explanation

This patent application describes a method for monitoring data traffic between a radio unit (RU) and a virtualized Radio Access Network (vRAN) instance. The vRAN instance is running on a server and is responsible for processing the physical layer (PHY) and Layer 2 (L2) of the data traffic.

• The method involves monitoring the data traffic during a first transmission time interval (TTI) between the RU and the vRAN instance.
• The first vRAN instance is running on a specific server and is responsible for PHY layer processing and L2 processing.
• Based on the data traffic observed during the first TTI, the method estimates the workload that the first vRAN instance will experience during a second TTI.

Original Abstract Submitted

During a first transmission time interval (TTI) of a vRAN, data traffic between a radio unit (RU) of a cellular network and a first vRAN instance of the vRAN is monitored. The first vRAN instance executes on a first server of the vRAN and the first vRAN instance is configured to perform PHY layer processing and L2 processing of the data traffic. Based on the data traffic between the RU of the cellular network and the first vRAN instance during the first TTI, a workload at the first vRAN instance during a second TTI is estimated.
