The invention discloses a method, system and device for realizing PS domain roaming restriction, belonging to the communication field, wherein the method includes the following steps: when a terminal user is accessed to a high-speed packet data network, positional information of a user can be obtained from a packet access gateway, and roaming permission information signed by the user can be obtained from an authorization, verification and charging AAA server; whether the positional information is matched with the roaming permission information signed by the user is judged; finally, according to the judgment, the invention carries out PS domain user roaming restriction. The system comprises a packet access gateway and an AAA server, wherein the AAA server comprises a positional information receiving unit, a first judgment unit and a first processing unit; the access gateway comprises a roaming permission information receiving unit, a second judgment unit and a second processing unit. Through expanding parameters, the invention transmits user positional information or roaming permission information signed by a user and realizes effective management of a roaming user; moreover, the invention solves the roaming restriction problem of a VoIP user, thereby lowering the operating risk of an operator.
