Example implementations described herein involve systems and methods that can involve detecting, from a device schedule indicating a schedule of a plurality of applications used by a plurality of mobile devices in a plurality of locations over a plurality of time slots, whether a bandwidth shortage will occur in each of the plurality of locations; and for detection that a bandwidth shortage will occur at a location in the plurality of locations, calculating a user priority of each of the plurality of applications on each of the plurality of devices at the location based on a bandwidth reduction efficiency and a staying time of the each of the plurality of devices at the location; and determining a bandwidth allocation for each application across the each device at the location and an edge server for managing one or more of the plurality of the applications based on the priority for use.
