Title:
MOBILE COMMUNICATION METHOD, MOBILE MANAGEMENT NODE, AND WIRELESS BASE STATION
Document Type and Number:
Japanese Patent JP2012217103
Kind Code:
A
Abstract:

To generate a mobile station intercommunication key for transmitting/receiving data signals via a Ud interface, by using a mechanism of an existing mobile communication system.

A mobile communication method includes: a step in which a mobile management node MME generates a key Kx to be used for security of data signals to be transmitted/received via a Ud interface, by using a key KASME1 managed only by the mobile management node MME and a mobile station UE#1 and a key KASME2 managed only by the mobile management node MME and a mobile station UE#2; a step in which the mobile management node MME transmits the key Kx to the mobile station UE#1 and the mobile station UE#2; and a step in which the mobile station UE#1 and the mobile station UE#2 transmit and receive data signals via the Ud interface by using the key Kx.
