Abstract: Embodiments of the present invention disclose a security processing method and system in a network handover process. The method includes: generating, by a network switching node, a target key after receiving a handover request; sending, by the network switching node, security information including the target key to a target network node, and receiving a handover response message sent by the target network node; and sending, by the network switching node, a handover command to a mobile terminal, so that the mobile terminal accesses a target network. By adopting the present invention, security processing in handover of a mobile terminal from a 3G network to an HSPA network or an LTE network may be completed in a case that the network switching node currently used in the network is not changed.

Abstract: Embodiments of the present invention provide an MTC device communication method, device, and system. A second network element receives, a query message sent by a first network element after the first network element identifies that a type of a received short message is a preset-type short message. The query message comprises an identifier of a receiver of the short message and an identifier of a sender of the short message. The second network element checks whether the sender is authorized to send the preset-type short message to the receiver. The second network element sends a message to the first network element indicating whether or not to send the short message to the receiver.

Abstract: Embodiments of the present invention provide a method and a related device for generating a group key. The method includes: obtaining a group ID of a group where a machine type communication MTC device is located; obtaining a group communication root key corresponding to the group ID; generating a group key corresponding to the group ID according to the group communication root key; and sending the group key encrypted by using an access stratum key of the MTC device to the MTC device, so that the MTC device obtains the group key through decryption according to the access stratum key of the MTC device. According to the foregoing technical solutions, a base station may allocate, to an MTC device, a group key corresponding to a group where the MTC device is located.
