Abstract
A wireless network allocates special base-station resources to mobile user devices in the inter-station overlapping fringes that are also serviceable by a neighboring base-station. Included-fringe mobile user devices interoperate with a base-station that has been assigned to handle those particular mobile user devices. If a central controller has assigned another base-station to service them, they are referred to as an excluded-fringe mobile user device. Mobile user devices that are not visible to other base-stations can access the general base-station resources, but not any of the special base-station resources reserved for overlapping fringe area use. If no mobile user devices are operating in the overlapping fringe areas, then all the special base-station resources can be returned to the main pool of general base-station resources. A global scheduler, one part of split-level scheduling, in the central controller determines the amount of special and general base-station resources. A local scheduler, another part of split-level scheduling, in the base station do fair-sharing of its resources among user devices within their allocated type of resources. Base station can use special …
