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.
