Why does mme initiates E-RAB modification procedure ?
The purpose of the E-RAB Modify procedure is to enable modifications of already established E-RABs for a given UE. This message is also initiated by MME, Whenever there is an requirement to change the QoS parameters for UE. MME will initiate this message and according to this E-NodeB will made the changes.
In LTE , after successful completion of attach-process , i want to fail the dedicated radio bearer , which is initiated by PGW ,what is the procedure to fail the dedicated radio bearer
I am looking for actual use of this procedure ?
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?
