Abstract:
1. An infrastructure station in a cellular mobile communication system, the infrastructure station comprising: an infrastructure station core configured to provide infrastructure station functionality to a plurality of dependent stations; a topographer configured to discover a network topology and designate a failover topology from the network topology for use in the event that the infrastructure station fails thereby no longer being capable of providing infrastructure station functionality to the plurality of dependent stations, the failover topology comprising failover stations; and a synchronizer configured to periodically provide timing estimates of dependent stations to failover stations such that network reentry after infrastructure station failure is shorter than normal network entry; wherein the infrastructure station is configured to process a SBC-REQ message from a dependent station when a dependent station performs network entry and requests infrastructure station functionality from the infrastructure station, the SBC-REQ message indicating that the dependent station is capable of being a failover station.
