    Abstract: An MME negotiates security in case of idle state mobility for a UE from a first network to a LTE network. The UE sends its security capabilities including non-access stratum (NAS) security capabilities supported by the UE to the LTE network. The MME selects a NAS security algorithm, in accordance with the NAS security capabilities of the UE, and sends the selected NAS security algorithm to the UE, sharing the NAS security algorithm between the UE and the LTE network when the UE moves from the first network to the LTE network. The MME also derives, in accordance with the selected NAS security algorithm, a NAS protection key from an authentication vector-related key so as to security communication between the UE and the LTE network.

    Abstract: A method, user equipment (UE) and system are provided for negotiating a security capability during idle state mobility of the UE from a non-long term evolution (non-LTE) network to a long term evolution (LTE) network. The UE sends UE security capabilities supported by the UE to the LTE network for a non-access stratum (NAS) security algorithm selection use. The UE then receives from the LTE network selected NAS security algorithm. The UE further generates a root key from an authentication vector-related key stored at the UE and then derives, from the generated root key, a NAS protection key for security communication with the LTE network.

    Abstract: A security capability negotiation method is applicable to perform security capability negotiation during a mobile network handover. Moreover, a security capability negotiation system is also provided. Consistent with the provided system and method, it may be unnecessary for the MME to know the security capability of the corresponding eNB in a certain manner during a handover from a 2G/3G network to an LTE network. Meanwhile, during the handover from the LTE network to the 3G network, the SGSN does not need to introduce new requirements.

    Abstract: A signaling attack prevention method and apparatus, where the method includes receiving a general packet radio service (GPRS) Tunneling Protocol (GTP-C) message from a public data network gateway (PGW), determining whether the GTP-C message is received from an S8 interface, determining whether a characteristic parameter of the GTP-C message is valid when the GTP-C message is received from the S8 interface, and discarding the GTP-C message or returning, to the PGW, a GTP-C response message carrying an error code cause value when the characteristic parameter of the GTP-C message is invalid. By determining validity of each parameter in the GTP-C message, a hacker is effectively prevented from attacking a serving gateway (SGW) using each attack path, and communication security is improved.
