The present disclosure discloses a method, an apparatus and a system for managing user access to a network. The method includes: carrying, by a mobile management apparatus, in a location update request a radio access type currently used by a user; and determining, by an access restriction management apparatus in accordance with the received radio access type currently used by the user and access restriction subscription data of the user stored therein, whether the user is allowed to get access to the network through the currently used access type, and, when it is determined the access is not allowed, directly returning a location update failure response to the mobile management apparatus, thereby avoiding unnecessary signaling load between the mobile management apparatus and one of an HLR and an HSS.
