<p>Methods and apparatus for improving the robustness of paging in wireless networks by defining separate signaling (502) and boundary paging areas (504) are described. Each boundary paging area (504) is a region used to control mobile node registration with a paging agent (506. There is a corresponding larger signaling paging area (502) into which paging signals are transmitted for each boundary paging area (5049. Signaling paging areas (502) normally have some overlap. Since the signaling paging area (502) is larger than the corresponding boundary paging area (504) a mobile node (510) may travel into a region into which it is supposed to register with a new paging agent (506), e.g., into a new boundary paging area (504), but still receive paging signals from the paging agent (506) with which it was just previously registered. Thus, failure to promptly detect entry into a new paging (504) area and to promptly register does not result in the loss of the ability to page a mobile node 510).</p> |
