1. A network virtualization method in a wireless communication system, the method comprising:

  • aggregating sets of uplink and downlink flows on a cellular basestation into groups;

    allocating wireless resources to each of the sets as a respective basestation slice; and

    enabling each of the sets of flows to be under a distinct administrative entity,wherein the wireless communication system is configured so that said administrative entity can request reservations for aggregate flows in terms of selected one of bandwidth and resources,wherein said cellular basestation allows optimal co-existence of said reservations using normalized weight functions per slice that are computed differently for resource-based and bandwidth-based types of said reservations,wherein said basestation enables said slices to perform customized slices, within each of which customization of resource allocation of each flow is provided for customized flow management functions and application optimizations, andwherein the customized flow management functions comprise a virtual time tagging, a scheduler selection to provide a variety of commonly employed schedulers that said administrative entity can choose one from and a model specification to provide a programming interface to specify weight distribution on a per-class or per-flow basis.
