Paging Metrics
Paging metrics provide measurements at the Central Unit Control Plane (CUCP) and the
Distributed Unit (DU). In a mobile network, when a device does not have any ongoing data
transmissions, it enters an IDLE state to preserve battery. If new data arrives for the
device, the network probes the IDLE device by sending a Paging message and the device
correspondingly responds.
Example of sample Paging
metrics.

The following table lists the JSON
definitions.
JSON | Description | Units |

number of paging records received by the gNB-DU for paging
occasion in each cell. | Double |
