  • Method, apparatus, and system for acquiring quality of service QoS control information
    Patent number: 9397908
    Abstract: A method, an apparatus, and a system for acquiring quality of service (QoS) control information. A policy control and charging rules function entity (PCRF) determines, according to a random algorithm, a time point in a time period from a receiving time of a request message sent by a policy and charging enforcement function entity PCEF for acquiring QoS control information to an update time of the QoS control information, as a time for the PCEF to reacquire QoS control information from the PCRF; and the PCEF reacquires QoS control information from the PCRF according to the time for reacquiring QoS control information from the PCRF that is carried in a response message returned by the PCRF, thereby avoiding execution of a QoS update by multiple PCEFs at a same time point, avoiding update message congestion, and improving an update speed of the QoS.
