MOBILE COMMUNICATION METHOD, RELAY NODE, AND RADIO BASE STATION

摘要

PROBLEM TO BE SOLVED: To strengthen security of signaling of an S1AP/X2AP layer transmitted and received in a Un radio section.

SOLUTION: The invention relates to a mobile communication method for transmitting and receiving signaling of an S1AP/X2AP layer on a DRB established between a radio base station DeNB and a relay node RN. The mobile communication method includes a step of generating a key KS1X2_intto perform integrity protection at the DRB in SMC (security mode command) processing performed in attach processing at the relay node RN.
