A method for configuring a path for intercepting user data, a method for intercepting user data, an apparatus, a system, a control plane entity and a user plane entity, the method for configuring the path for intercepting user data comprises: acquiring a target to be intercepted and an intercepting interface address; configuring data path configuration information on a user plane entity GW-U according to the target to be intercepted and the intercepting interface address; sending the data path configuration information to the user plane entity GW-U so that the GW-U establishes a path for data transmission; initiating an establishment of an intercepting connection of an intercepting interface to an intercepting entity based on the intercepting interface address so as to transmit the data of the target to be intercepted. The embodiments of the present invention decrease data flow of the target to be intercepted between the control plane entity and the user plane entity significantly as well as simplifying the structure complexity of the control plane entity, improve performance of the GW-C and reduce cost.
