Abstract

Embodiments of wireless packet-switched paging apparatus, systems, and methods are described generally herein. Other embodiments may be described and claimed.

Claims

1. A method, including:

2. The method of claim 1, wherein the power management protocol includes:

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

exiting the idle state following the idle period;

receiving a first paging advertisement at the mobile node from a first paging base station upon exiting the idle state, the first paging advertisement triggered by the first paging controller module; and

sending a location update message from the mobile node to the first paging base station in response to the first paging advertisement.

3. The method of claim 2, further including:

upon exiting the idle state, receiving at the mobile node at least one packet buffered in the first paging controller module.

4. The method of claim 1, further including:

registering the mobile node with the first paging controller module before the mobile node enters an idle state.

5. The method of claim 1, further including:

maintaining a first paging database using the first paging controller module, wherein the first paging database includes at least one entry representing the mobile node, the at least one entry to be maintained while the mobile node is in an idle state.

6. The method of claim 5, wherein the at least one entry comprises at least one of a paging controller identification, a paging group identification, and an identification associated with the first aggregation router, wherein the first aggregation router originates the packet stream to be directed to the mobile node.

7. The method of claim 1, further including:

moving the mobile node within an area of radio-frequency coverage associated with the first paging group without performing a location update unless the mobile node is paged.

8. The method of claim 1, further including:

providing a paging message to the mobile node upon command from the first paging controller module; and

receiving a location update from the mobile node at the first paging controller module in response to the paging message.

9. The method of claim 1, further including:

moving the mobile node from a first area of radio-frequency (RF) coverage associated with the first paging group to a second area of RF coverage associated with a second paging group;

receiving a second paging advertisement at the mobile node from a second paging base station located in the second paging group;

at the mobile node, comparing at least one of a paging controller identification associated with the second paging advertisement and a paging group identification associated with the second paging advertisement to at least one of a paging controller identification stored in the mobile node and a paging group identification stored in the mobile node, respectively; and

at the mobile node, inferring from the comparison that the mobile node has moved from the first area of RF coverage to the second area of RF coverage.

10. The method of claim 9, further including:

communicating the paging controller identification stored in the mobile node to the second paging base station;

at the second paging base station, comparing the paging controller identification stored in the mobile node to the paging controller identification associated with the second paging advertisement; and

upon recognizing that the paging controller identification stored in the mobile node and the paging controller identification associated with the second paging advertisement are different, communicating the paging controller identification stored in the mobile node from the second paging base station to a second paging controller module within a second aggregation router associated with the second paging group.

11. The method of claim 10, farther including:

communicating from the second paging controller module to the first paging controller module to advise the first paging controller module that the mobile node has moved to the second paging group;

receiving a response at the second paging controller module from the first paging controller module including at least one paging group identification parameter stored in the mobile node and an identification associated with the first aggregation router, wherein the first aggregation router originates the packet stream to be directed to the mobile node;

storing the at least one paging group identification parameter and the identification associated with the first aggregation router in a second paging database associated with the second paging controller module; and

updating and storing within the mobile node at least one of a second paging group identification associated with the second paging group and a second paging controller identification associated with the second paging controller module.

12. The method of claim 11, wherein communications between the first paging controller module and the second paging controller module traverse at least one of a backhaul network or a network backbone.

13. The method of claim 1, further including:

establishing a packet stream forwarding route between the first aggregation router and a second aggregation router associated with a second paging group upon moving the mobile node from a first area of radio-frequency (RF) coverage associated with the first paging group to a second area of RF coverage associated with the second paging group.

14. The method of claim 13, wherein the packet stream forwarding route comprises an Internet protocol tunnel.

15. The method of claim 1, further including:

buffering the packet stream while the mobile node moves between the first paging group and a second paging group.

16. The method of claim 15, wherein the packet stream is buffered in the first paging controller module.

17. The method of claim 15, wherein the packet stream is buffered in a second paging controller module within a second aggregation router associated with the second paging group.

18. The method of claim 1, further including:

performing an operation defined by at least one of a mobile-Internet protocol or an Institute of Electrical and Electronic Engineers 802.16e protocol using the first paging controller module.

19. An article including a machine-accessible medium having associated information, wherein the information, when accessed, results in a machine performing:

localizing a mobile node operating according to a power management protocol to a first paging group within a wireless packet-switched network using a first paging controller module within a first aggregation router associated with the first paging group; and

directing a packet stream to the mobile node using the first paging controller module.

20. The article of claim 19, wherein the information, when accessed, results in a machine performing:

21. The article of claim 19, wherein the information, when accessed, results in a machine performing:

providing a paging message to the mobile node upon command from the first paging controller module; and
