METHOD OF MOBILE COMMUNICATION, BASIC RADIO COMMUNICATION STATION AND MOBILE STATION Russian patent published in 2012 - IPC H04W12/04 

FIELD: information technologies.

SUBSTANCE: method includes a step to generate an intermediate key (K_ekv*) handover in an initial basic radio communication station by substitution of a basic station key (K_eNB*) into the first function KDF (*), information of identification (PCI) of a handover purpose cell and information of identification (ARFCN) on a frequency for the handover purpose cell, and to transfer an intermediate key (Ke_NB*) handover from the initial basic radio communication station into the target basic radio communication station in process of handover operation, and a step to generate a key (K_eNB) of the basic station in the target basic radio communication station on the basis of the intermediate key (K₆nb*) during realisation of the handover operation.

EFFECT: invention provides for security of a communication network due to provision of maximum uniqueness of an intermediate key in multiple cells in process of handover.
