Method for configuring a path for intercepting user data, method for intercepting, apparatus and entity

A method for intercepting user data comprising:

• sending, by a control plane entity, data path configuration information to a user plane entity;
• receiving, by the user plane entity, the data path configuration information from the control plane entity,
• wherein the data path configuration information comprises identifier information of a target to be intercepted and an interface address of an intercepting entity;
• establishing, by the user plane entity, a path for data transmission according to the data path configuration information;
• sending, by the control plane entity, a connection identifier of an intercepting interface for the path to the user plane entity;
• receiving, by the user plane entity, the connection identifier from the control plane entity;
• intercepting, by the user plane entity, data transmitted by the target to be intercepted on the path;
• and
• sending, by the user plane entity, the data to the intercepting entity through the interface address according to the connection identifier.
