36.321中,只有一处地方会在Msg3的时候带上C-RNTI:
if the transmissionis not being made for the CCCH logical channel, indicate to the Multiplexingand assembly entity to include a C-RNTI MAC control element in the subsequentuplink transmission.
即Msg3不是通过CCCH发上来的时候,那么这种情况只会对应HO。而RRC建立请求和重建立请求都是走的CCCH。因此,这个C-RNTI的MAC CE是不带的。

是用于验证UE的接入层安全模式是否已经激活,36.331 5.3.7.1说的很明白:If AS security has not been activated, the UE does not initiate the procedure but instead moves to RRC_IDLE directly.
