The invention belongs to the technical field of communication, and particularly relates to a method and equipment for protecting specific user location information in an IMS network. The method is implemented according to the following steps: acquiring request data of a target user in an IMS network session request message according to an SIP field; for the request data of the target user, constructing corresponding virtual location data which is used to cover original identity location information of the target user, and storing the request data of the target user and the constructed corresponding virtual location data; replacing the original identity location information in the request data of the target user with the virtual location data, and forwarding a session request message obtained after the replacement to the IMS network; and receiving response data of the IMS network session request message, restoring the original identity location information in the response data according to an information cache module, and sending response data obtained after the restoration to a user terminal. The method and equipment provided by the invention has the advantages that a network location of the specific target user can be effectively protected, high safety and reliability is achieved, and the method and equipment can be widely applied to specific target users who are sensitive to network location privacy.
