Abstract
Provided are a method and apparatus for acquiring security context. The method comprises: a user plane gateway receiving a PDU session establishment request from a UE, wherein the PDU session establishment request is used for requesting the establishment of a PDU session between the user plane gateway and the UE, and the PDU session is carried between the UE and a service server of a data network; and the user plane gateway and the UE respectively acquiring security context used for the PDU session, and activating user plane security protection based on the security context. Therefore, in the case of PDU session re-establishment, for example, PDU session re-establishment triggered by switching of a user plane gateway, a session management network element, etc., the user plane gateway and the UE can acquire new security context, thereby realizing end-to-end protection between the UE and the user plane gateway.
