    Abstract: The present invention relates to a counter check and reconfiguration method, apparatus, and system. The method includes: sending a second identity information and a second count information to a terminal, so that the terminal compares, according to the second identity information, the second count information with third count information maintained by the terminal itself to obtain first comparison result information or second comparison result information; receiving the first comparison result information sent by the terminal, or the second identity information and second comparison result information sent by the terminal; and determining counter check result information according to the received first comparison result information, or the received second identity information and second comparison result information. Thereby, the present invention implements a counter check process and a reconfiguration process in a network architecture in which a primary base station is separated from a secondary base station.

    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.
