Hi,
SRB1 is to manage over the air connection and SRB2 is to manage mobility. If ENB sends SRB1 data then it maybe an reconfiguration or connection release. In this case if over the air connection is releasing or re configuring then that should be more priority than SRB2.
we know SRB0 is for rrc message on ccch , SRB1 rrc +nas messages on DCCH and SRB 1 has higher priority than SRB2 ok then y SRB2 is implemented ? when SRB 2 is used ? which type of messages v can expect in SRB2 ?
