Claim 7:
8. A method for providing security policy in a wireless network, the method comprising:
transmitting, by a base station to a user equipment (UE), an access stratum (AS) security mode command (SMC) message during an AS SMC procedure, the AS SMC message being integrity protected with a RRC integrity key and indicating a first integrity protection algorithm and a first encryption algorithm for a radio resource control (RRC) traffic signaling protection procedure between the base station and the UE;
receiving, by the base station from the UE, a security command complete message that is integrity protected with the RRC integrity key and the first integrity protection algorithm as indicated in the AS SMC message; and
transmitting, by the base station to the UE during a data radio bearer (DRB) establishment procedure that is performed after receiving the security command complete message, a RRC message comprising a user plane (UP) integrity indication and a UP encryption indication for a DRB of a protocol data unit (PDU) session between the base station and the UE.
