Abstract:
A communication method includes receiving by a SGSN a context request message from a mobility management entity (MME), obtaining by the SGSN an authentication vector-related key, and calculating by the SGSN a root key according to the authentication vector-related key. In addition, the method further includes sending by the SGSN a context response message including the root key to the MME, wherein the MME derives a NAS protection key according to the root key.

Claim (Index 1):
A mobility management entity (MME) performing security negotiation for idle state mobility from a third generation (3G) network to a long term evolution (LTE) network, comprising:\n a receiver configured to receives from a user equipment (UE) security capabilities of the UE including non-access stratum (NAS) security capabilities of the UE, and receive an authentication vector-related key from a service general packet radio service (GPRS) support node (SGSN) in the 3G network; a processor configured to select a NAS security algorithm supported by the NAS security capabilities of the UE, and derives a NAS protection key with the selected NAS security algorithm from the authentication vector-related key; and a transmitter configured to send a message that indicates the selected NAS security algorithm from the MME to the UE.
