ABSTRACT:
A mobile communication method according to the present invention includes steps of: generating, at a HO-source radio base station, an intermediate key (KeNB*), by inputting, into a first function KDF (*), a base station key (KeNB), identification information (PCI) of a HO-target cell, and identification information (ARFCN) of a frequency for the HO-target cell; and transmitting, from the HO-source radio base station to a HO-target radio base station, the intermediate key (KeNB*), in the HO process; and generating, at the HO-target radio base station, a base station key (KeNB) on the basis of the intermediate key (KeNB*) in the HO process.
