Non GBR
Non Guaranteed Bit Rate

In LTE Dedicated bearers carry traffic for IP flows that have been identified to require a specific packet forwarding treatment. Dedicated bearers can be either GBR (Guaranteed Bit Rate) or non-GBR. A GBR bearer has a guaranteed bit rate and MBR (Maximum Bit Rate) while more than one non-GBR bearer belonging to the same UE shares an AMBR (Aggregate Maximum Bit Rate). Non-GBR bearers can suffer packet loss under congestion while GBR bearers are immune to such losses. Consequently these bearers are generally subject to admission control within the network.
