Abstract: A method, system and device for implementing security control are provided. The method for implementing security control includes: receiving, by the Policy and Charging Enforcement Function (PCEF) entity, security control policy information from the Policy Control and Charging Rules Function (PCRF) entity; and executing, by the PCEF entity, user security control according to the security control policy information. The provided method, system, and device may provide security control for the user session in the Policy Charging Control (PCC) architecture.

Abstract: A method for implementing data service security in a mobile communication system includes: obtaining security condition of a user terminal based on security-relevant configuration information reported by the user terminal; determining a security policy for the user terminal based on the security-relevant configuration information of the user terminal and security policy information stored, and sending the security policy determined to a packet service support node and/or the user terminal; implementing, by the packet service support node and/or the user terminal, a control process based on the security policy. The method, system and apparatus provided by the embodiments of the present invention introduce a security mechanism cooperated by the mobile communication network and a user terminal to effectively prevent the mobile communication network against viruses.
