MOBILE COMMUNICATION METHOD, RELAY NODE AND WIRELESS BASE STATION

摘要

The disclosed mobile communication method sends and receives signaling of an S1SP/X2AP layer on a DRB established between a wireless base station (DeNB) and a relay node (RN), wherein the SMC (security mode commands) processing performed in attachment processing of the relay node (RN) involves a step for generating a key (Ks1x2_int) for implementing integrity protection on the aforementioned DRB.
