    Abstract: A method for predicting information propagation in a social network includes acquiring target information to be predicted, and acquiring influences of K clusters, where the target information is posted or forwarded by a first user at a first moment, and K is a positive integer; determining a role probability distribution of the first user, and determining a second user who has not propagated the target information, where the role probability distribution of the first user is used to indicate probabilities that the first user belongs separately to the K clusters; and determining, according to the influences of the K clusters and the role probability distribution of the first user, a probability that the second user forwards the target information from the first user. In the embodiments of the present application, propagation of target information in a social network can be predicted by using influences of K clusters.

    Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for QoS control based on a charging system. In solutions provided by the embodiments of the present invention, after a service resource reservation request from a PCEF is received, a preset QoS value for a service may be directly determined according to a service identifier of the service from a locally stored mapping relationship between service identifiers and preset QoS values of services, and a QoS value for the service is determined according to the preset QoS value, and the determined QoS value is directly delivered to the PCEF, so that the QoS value for the service may be determined and delivered without the participation of the PCRF, so as to significantly reduce the time for determining the QoS value for the service.

    Abstract translation: 本发明的实施例提供了一种基于充电系统的QoS控制的方法,装置和系统。 在本发明的实施例提供的解决方案中,在接收到来自PCEF的服务资源预留请求之后,可以根据本地存储的业务映射关系根据业务的服务标识直接确定业务的预设QoS值 服务的标识符和预设QoS值,并且根据预设的QoS值确定服务的QoS值,并且确定的QoS值被直接传递到PCEF,使得可以确定和传送服务的QoS值而不用 PCRF的参与,以便显着减少用于确定服务的QoS值的时间。
