Service Provisioning Using Abstracted Network Resource Requirements

摘要

Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

1. A method for wireless network virtualization, the method comprising:
identifying, by a controller, virtual links in a wireless network, the virtual links including at least a first virtual link corresponding to a first radio interface and a second virtual link corresponding to a second radio interface, wherein the first radio interface and the second radio interface are available for carrying traffic in the wireless network; obtaining, by the controller, resource cost data for the wireless network; and generating, by the controller, a resource cost database for the wireless network in accordance with the resource cost data, the resource cost database specifying an interference cost on the first virtual link as a function of loading on the second virtual link, wherein the resource cost database is configured to be used for provisioning resources in the wireless network.
