Let us consider the radio resource connection establishment procedure initiated by an LTE UE toward its RAN E‐UTRAN. To initiate this procedure, a UE makes the radio resource requests and sends the RRCConnectionRequest message to the E‐UTRAN, shown in Figure 3.11, which is reproduced from TS 36.331 [94]. The RRCConnectionRequest is an AS RRC layer message that terminates at the E‐UTRAN end; refer to TS 36.331 [94]. This figure shows the RRC layer message names without showing the contents of each message.
