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 can provide an inter-cell handover method and a controller to shorten a handover delay. For achieving such, a target cell can be determined by a first controller of a source cell. The first controller can send a pre-handover request to a second controller, which may be a controller of the target cell. The pre-handover request can be configured for instructing the second controller to allocate a first resource for a cell handover to a terminal device. The first controller can send a handover command to the terminal device when the first controller determines that the terminal device meets a handover condition. The handover command can be configured for instructing the terminal device to be handed over from the source cell to the target cell based on the first resource.
