This KPI evaluates the percentage effectiveness of the network in successfully initiating RRC connections for data sessions, voice calls, and other communication activities. The RRC connection is a critical component of the signaling process that facilitates the establishment and maintenance of communication between a mobile device and the base station.
This KPI refers to the percentage of successfully completed handovers between different cells (base stations) within a 4G network. This KPI assesses the network's efficiency in transitioning an ongoing call or data session from one cell to another as a user moves within the coverage area.
This KPI measures the percentage of successfully established radio access bearer channels out of the total attempted connections. A radio access bearer (RAB) channel is a logical communication pathway that allows data to flow between a user's device and the cellular network. The eRABSR KPI evaluates the network's ability to efficiently set up and maintain these bearer channels, which are essential for data services like internet browsing and multimedia streaming.
This KPI measures the rate at which radio access bearer channels are prematurely terminated or dropped in the 4G network. Bearers in 4G are channels used to transmit data and services between the user's device and the network infrastructure.
This KPI measures the efficiency of the network in preparing the necessary resources and signaling for a seamless transition from 4G to an older network technology (2G or 3G) to support voice calls. CSFB is a mechanism that allows a 4G device to fall back to a 3G or 2G network for voice calls, as 4G networks primarily use packet-switching technology.
