Zusammenfassung:	Embodiments of the present invention provide a method, an apparatus, and a system for acquiring quality of service QoS control information. A PCRF determines, according to a random algorithm, any time point in a time period from a receiving time of a request message sent by a PCEF for acquiring quality of service QoS control information to an update time of the quality of service QoS control information, as a time for the PCEF to reacquire quality of service QoS control information from the PCRF; and the PCEF reacquires quality of service QoS control information from the PCRF according to the time for reacquiring quality of service QoS control information from the PCRF that is carried in a response message returned by the PCRF, thereby avoiding execution of a quality of service QoS update by multiple PCEFs at a same time point, avoiding update message congestion, and improving an update speed of the quality of service QoS.
