What to read next Radio Resource Utilization MetricsRadio Resource Utilization (RRU) metrics provide Distributed Unit (DU) measurements between gNodeB and the User Equipment (UE). This metric also provides operators the load information of the radio network during the measurement time period. Carrier MetricsCarrier metrics provide metrics for physical uplink or downlink shared channel radio bearers at Distributed Unit (DU). Paging MetricsPaging 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. Mobility Management MetricsMobility Management (MM) is one of the most significant feature of the mobile networks, and Handover is one typical action of mobility. Centralized Unit User Plane MetricsCentralized Unit User Plane (CUUP) provides metrics at the CUUP. Radio Resource Control MetricsThe Radio Resource Control (RRC) provides metrics for Centralized Unit Control Plane (CUCP) and other connection establishment related functionalities such as success attempts, re-establishment, and active number of connections. Quality of Service MetricsYou can calculate Quality of service (QoS) metrics per 5QI, per slice at CUCP and at CUUP. Random Access Channel MetricsA Random Access Channel (RACH) is a shared channel used by User Equipment (UE) to access the mobile network for call set up and bursty data transmission. Whenever a mobile makes a Mobile Originating (MO) call, it schedules the RACH. RACH is a transport layer channel, and the corresponding physical layer channel is Physical Random Access Channel (PRACH). Automatic Neighbor Relation MetricsThe Automatic Neighbor Relation (ANR) resides in the gNB and manages the Neighbor Relation Table. Domain Radio Bearer MetricsThe Domain Radio Bearer (DRB) metrics measures the number of radio bearer establishment attempts or successes at CUCP. Session Management MetricsThe Session Management (SM) metrics measures the number of CUCP PDU session setups. Transport Blocks MetricsThe Transport Blocks (TB) metrics measures the intial uplink or downlink percentage at DU. Physical Layer MetricsThe Physical (PHY) layer uses the physical uplink shared channel to measure the noise power and the number of allocated PUSCH Radio Bearers (RBs) for a UE in time period T. Medium Access Control Layer MetricsThe Medium Access Control (MAC) layer metrics provides the total number of QAM and QPSK modulation used in DL MAC HARQ. User EquipmentThe User Equipment (UE) metrics provides the number of release failures for RLC and other categories. Cell MetricsThe Cell metrics provides measurements for uplink and downlink bandwidth, cell unavailable time, number of dynamically scheduled UEs in uplink and downlink, and cell activation and deactivation based on the number of MAC CEs sent.
