In embodiments of the present application, an application component obtains location information of a user from a first application, and then obtains an application partition of the user in a second application according to the location information of the user, so that the application component associates the user to the application partition and implementing the application partition of the user.

Abstract: The present invention discloses an energy-saving deployment method of a virtual CDN. According to the historical flow data of the virtual CDN and the prediction model (ARIMA) in the controller, the network peak flow in the next time period is predicted. Next, the scale of the virtual CDN system at the next moment is calculated according to the peak flow. Meanwhile, several redundant servers are added to correct the prediction error. The network flow is aggregated to the desired virtual servers based on the calculation of the controller through a load balancer. In this way, the utilization rate of the virtual CDN system can be increased, and the energy consumed due to the higher utilization rate of the CDN system is saved.

Abstract: The present invention provides a method for associating a user with a base station based on backhaul capacity in heterogeneous cellular network. First, an available base station set is obtained through the SINRs, and the downlink data rate between the new user and each base station in the available base station set is calculated according to the SINR between them; Then, the usable link capacity factor of each base station is calculated based on the used link capacity and the backhaul capacity; Finally, the optimal base station is selected for the new user i under a constraint which is constructed by the bandwidth of the new user and the usable link capacity factor. The backhaul capacity of each base station is taken into account in selecting the optimal base station to associate with for the new user, thus the real time of user association and the overall performance of heterogeneous cellular network can be guaranteed.
