Hi All,
It is mentioned in different websites that in LTE max. of 8 DRB can be established per UE. But as per page 652 of 36.331 V13.2.0, the max no. of DRB is 11.
"maxDRB INTEGER ::= 11 -- Maximum number of Data Radio Bearers"
Based on what source are we saying that max. DRB in LTE is 8 and not 11.
It was mentioned in one of the old threads the following:
If EPS bearer ID is = x +4 ;
Then
DRB ID = x;
Logical Channel ID = x + 2
I found the above relationship of DRB ID & EPS Bearer ID to be true for one of the eNB vendors but not for another one.
Example:
EPS ID is 5 and DRB ID is 4 instead of 1. Can somebody comment in this?
NOTE : All these ranges is with respect to DRB establishment
EPS Bearer ID Range is INTEGER (0..15) (But 0-4 is reserved so we use starting from 5 )
DRB ID Range is INTEGER (1..32) (As in LTE max 8 DRB can be established per UE so we use from 1-8)
Logical Channel ID range for DRBs is INTEGER (3..10) ( For for DRB1 we use 3 as logical channed ID)
Thanks
