ABSTRACT:
A system and method is provided that enables the transfer of policy resource tokens (PRT) in the process of a handover of a mobile node in a wireless network. The system includes a granting agent that grants the PRT to a first access router to enable the mobile node to access network resources. In one embodiment, in the process of handing over the mobile node, the first access router provides the PRT to the second access router, thereby reducing data latency, and a disruption for an application executing on the mobile node. In another embodiment, the mobile node provides the PRT to the second access router after connectivity is established. A PRT data structure also is provided that includes a data field of profile types. A profile type describes context authorization information for granting access to a network resource.
