Abstract:
A method in a User Equipment (UE) of an Evolved Packet System (EPS) establishes a security key (K_eNB) for protecting Radio Resource Control/User Plane (RRC/UP) traffic exchanged with a serving eNodeB. The method comprises sending a Non-Access Stratum (NAS) Service Request to a Mobility Management Entity (MME), the request indicating a NAS uplink sequence number (NAS_U_SEQ). The method further comprises receiving an indication of the NAS_U_SEQ of the NAS Service Request sent to the MME, back from the MME via the eNodeB. The method further comprises deriving the K_eNB from at least the received indication of the NAS_U_SEQ and from a stored Access Security Management Entity-key (K_ASME) shared with said MME.

Claim (Index 11):
The method according to  claim 7 , comprising the step of receiving an indication of the NAS_U_SEQ of the NAS Service Request sent to the MME, back from the MME via the eNodeB.
