Who will assign max bit rate for uplink and downlink?guranteed bit rate for UL and DL?

Question

Is there any scheme for eNB to inform UEs to change their UL bit-rate? Or is it entirely dependent on the bandwidth/PRBs allocated??

Answer 1

It is all about subscription which is stored in HSS and used by nodes such as PGW and eNodeB during the data flow.
During establishment of default or dedicated bearer, QoS information associated with the bearer is transferred to PGW as well as eNodeB.
eNodeB MAC scheduler takes care of QoS. There are so many parameters are considered at MAC layer while scheduling data and channel condition. Each company has its own scheduler. Scheduler algorithm is not defined in 3GPP specification.

In attach procedure in create session request it is transferred from MME to SGW. How does MME will come to know about it? Will it come come to know before attach procedure?
