Abstract:
A method for handing off one of a plurality of mobile nodes in a wireless network having a core network (CN), the method comprising:examining overload factors at a first radio access network (RAN) serving the plurality of mobile nodes, wherein the first RAN is coupled to the CN; examining the CN for admission capabilities to neighboring cells; determining a traffic situation of the neighboring cells, wherein the determination includes analyzing an availability of at least one resource based on a service level associated with the mobile node; monitoring a cell containing a plurality of mobile nodes of a specified service level, wherein a resource reservation is triggered in the neighboring cells in anticipation of a handoff when a predetermined threshold is met; reserving at least a portion of the resource to ensure a level of availability based on the service level prior to knowing which neighboring cell will receive the handoff; and admitting a mobile node to one of the neighboring cells based on results of the examinations and the determination, wherein admitting the mobile node includes allocating the portion of the resource to the mobile node.
