RB is a set of connection formats between UE and UTRAN, that is, the formats of UU port L 1 and L2, that is, the configuration of physical channel, transmission channel and logical channel. If there is no service, RB is unnecessary. Therefore, to transmit signaling between CN/URTRN and UE, as long as there is RRC connection (in fact, there is also a radio bearer, that is, SRB), but as long as there is business, RB must be configured. Similarly, the bearer of Iub must be configured (as long as there is DCH, the bearer of DCH FP must be configured, just like RL).

As for SRB, it is actually RB, which is also a service provided by RLC, except that they are used to carry control messages of the control plane, so as to distinguish them from RB, they are called SRB. RB is a radio bearer between RNC and UE, and it is a transparent direct transmission between RNC and NodeB before transmission between NodeB and UE.
