Abstract: The present application generally relates to wireless communication technology. More particularly, the present application relates to a method and apparatus for performing protection control in a core network with separation between control plane and user plane. The present application also relates to computer program product adapted for the same purpose. According to one embodiment, a method for performing protection control in a core network with separation between control plane and user plane, comprises the following steps performed on the user plane: —a) pairing a User Plane Function (UPF) and at least one User Plane Security Function (UPSF); and —b) notifying a pairing relationship between the UPF and the UPSF to the control plane so that the pair of the UPF and the UPSF can be controlled by a Control Plane Function (CPF) via the same reference point.
