Resource optimization in a wireless IP network

摘要

A method and apparatus in accordance with the present invention provide for releasing resources dedicated to a dormant mobile station in a region served by a first network access server that has migrated to in a region in an IP network served by a second network access server to allow those released resources to be allocated more efficiently. Generally the invention includes defining logic with a Authentication, Authorization and Accounting facility (AAA) and within a network access server for triggering a release of network access server (NAS) resources allocated for a given Mobile Station (MS) when the MS moves to a physical location requiring service by a different NAS.
