In short, for a GBR bearer eNodeB reserves the radio resources even though there is no data transmission on going over the bearers.
As per my understanding, default bearer with GBR qos is not good way to utilize radio resources.

In LTE, when UE is first time attached to a network, it is usually allocated a default non-GBR bearer. Can this bearer be converted to a GBR bearer, without releasing the UE context at eNodeB?

Hello all,

Can anybody suggests how we can set maximum bitrates for parameters like MBR, GBR (UL,DL), APN-AMBR(UL/DL), UE-AMBR(UL/DL) for GBR and Non GBR bearer.?

Are those values standard from PCRFor does it define dynamically based on user subscription.?
Please suggest some sources to choose the exact the bitrates for QoS parameters mentioned above.

Thanks in advance,
Naveen.
