Title:
MOBILE COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/068799
Kind Code:
A1
Abstract:
The present invention protects a key (K_eNB-int) and a key (K_eNB-enc) which are used by a wireless base station (MeNB), even when a malicious third person has stolen a key (K_SeNB) from a wireless base station (SeNB). A mobile communication method according to the present invention has a step in which, upon start of "Inter-eNB carrier aggregation" (CA) configured so that downlink data is distributed to the wireless base station (MeNB) and the wireless base station (SeNB) by a serving gateway device (S-GW), the wireless base station (MeNB) generates the key (K_SeNB) on the basis of a key (KeNB) and transmits the generated key (K_SeNB) to the wireless base station (SeNB), and a step in which the wireless base station (SeNB) generates, on the basis of the generated key (K_SeNB), the key (K_SeNB-enc) and the key (K_SeNB-int) which are used for communication between a mobile station (UE) and the wireless base station (SeNB) in the "Inter-eNB CA."
