13. The system of claim 12, wherein the first MPC is communicatively coupled to a second MPC associated with the second paging group, the second MPC to receive a notification from a second paging controller that the mobile node has moved into a second RF coverage area, to notify the first MPC that the mobile node has moved into the second RF coverage area, to cause any packets buffered by the first paging controller to be forwarded to the second paging controller, and to establish a forwarding route through the network to the second paging controller.

14. A method, including:

localizing a mobile node to a first paging group within a wireless packet-switched network (WPSN) using a first master paging controller (MPC) collocated with an MPC base station associated with the first paging group; and

establishing a packet forwarding route through the network to deliver a packet to the mobile node.

15. The method of claim 14, further including:

grouping a plurality of base stations including the MPC base station into a first paging group, wherein a paging controller is collocated with each base station;

selecting one of the paging controllers as the first MPC; and

denominating the paging controllers not selected to be the first MPC as slave paging controllers.

16. The method of claim 14, further including:

maintaining a first paging database using the first MPC, wherein the first paging database includes idle-mode retention information associated with the mobile node, the idle-mode retention information to be maintained while the mobile node is in an idle state; and

registering the mobile node with the first MPC before the mobile node enters the idle state.

17. The method of claim 16, wherein the idle-mode retention information comprises at least one of a paging controller identification (PCID) associated with the first MPC and a paging group identification (PGID) associated with the first paging group.

18. The method of claim 17, further including:

storing the PCID and the PGID in the mobile node;

placing the mobile node in the idle state for an idle period;

exiting the idle state following the idle period;

notifying the first MPC that the mobile node has exited the idle state; and
