METHOD, APPARATUS AND SYSTEM FOR SECURITY PROCESSING IN SWITCH PROCESS

摘要

A method, an apparatus, and a system for security processing in a handover process in the field of communication technologies are provided, including: in a handover preparation and handover execution processes performed by a user equipment UE and a source node and a target node on a network side, obtaining, by the target node, security capability information of the UE provided by the source node or a security verification entity, where the security verification entity includes a gateway in case of UE handover under a NodeB or a donor NodeB in case of UE handover under a relay node; and if the source node provides the security capability information of the UE, the method further includes: sending a path modification ACK message to the target node if the security verification entity verifies that the security capability information of the UE carried in the path modification request message is consistent with locally stored security capability information of the UE. Embodiments of the present invention ensure that the target node can select appropriate security algorithms, thus further improving security of the optimized handover process.
