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.

Further, the first base station transmits one or more packets of the plurality of packets corresponding to the first fragment to the mobile station. The method further includes initiating a handover of the mobile station to at least one second base station. The at least one base station caches a remaining plurality of packets corresponding to the first fragment of the content in response to the handover.

Abstract: The present invention provides methods and systems for transmitting content in a wireless communication network. The method includes caching a content in each base station of a set of base stations in the wireless communication network. The content includes a plurality of packets. In response to caching the content, a first base station belonging to the set of base stations transmits a first group of packets of the content to a mobile station. The method further includes handing over the mobile station to a second base station. The second base station belongs to the set of the base stations. The second base station resumes transmission of a second group of packets of the content to the mobile station.
