Abstract: The present invention provides a network topology hiding method and device. The method includes: receiving a first service request, where the first service request is sent by a subscriber through a first network function entity and includes a name of the first network function entity and a subscriber identifier; determining a virtual name set corresponding to the name of the first network function entity, where the virtual name set includes at least two virtual names; and determining one virtual name from the virtual name set, and replacing the name of the first network function entity with the determined virtual name. The unfixed replacement further ensures effectiveness of network topology hiding.
