QoS Class Identifier (QCI)

In LTE dedicated bearers carry traffic for IP flows that have been identified to require a specific packet forwarding treatment. QCI determines which bearers are categorized as Guaranteed Bit Rate (GBR level 1-4) and which as Non-Guaranteed Bit Rate (GBR level 5-9). The priority associated with each QCI is applied when forwarding packets across the LTE network.
