Method and apparatus for mobile internet protocol regional paging
First Claim
1. A mobile internet protocol regional paging network having a visited-domain mobility agent for handling a regional registration of a mobile node visiting a paging area,the mobile node having an idle mode module for periodically providing an idle mode request to the visited-domain mobility agent containing information that the mobile node is entering an idle mode so as to deactivate one or more components for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network,the mobile node negotiating a time slot based paging scheme with the visited-domain mobility agent.

Abstract
A mobile internet protocol regional paging network 10 includes a paging foreign agent for handling a regional registration of a mobile node visiting a paging area, which includes internet protocol subnetworks. In operation, the mobile node periodically can provide an idle mode request to the paging foreign agent to enter an idle mode so as to deactivate one or more components for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network. The invention provides a small and link-layer independent extension to Mobile Internet Protocol with Regional Registrations to support power-constrained operation in the mobile nodes and to reduce routing state information in the visited domain. The extension allows a Mobile Node to enter a power saving Idle Mode during which its location is known with the coarse accuracy defined by a Paging Area. The mobile node and the visited domain may optionally agree on time slots used for Agent Advertisements and paging. The mobile node 14 may include a mobile phone, a pager, or any telecommunications device capable of wireless communicating, including communication over the internet.

1. A mobile internet protocol regional paging network having a visited-domain mobility agent for handling a regional registration of a mobile node visiting a paging area,
the mobile node having an idle mode module for periodically providing an idle mode request to the visited-domain mobility agent containing information that the mobile node is entering an idle mode so as to deactivate one or more components for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network, the mobile node negotiating a time slot based paging scheme with the visited-domain mobility agent.

16. A method for entering an idle mode in a mobile internet protocol regional paging network having a visited-domain mobility agent for handling a regional registration of a mobile node visiting a paging area, the mobile node having a plurality of components that consume energy when activated, characterized in that the method comprises the steps of:
-
periodically providing with the mobile node an idle mode request to the visited-domain mobility agent containing information that the mobile node is entering an idle mode so as to deactivate one or more components of the mobile node for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network; and negotiating a time slot based paging scheme with the visited-domain mobility agent and agreeing on time slots used for paging area advertisements and paging within the paging area. - View Dependent Claims (17)

18. A mobile node for entering a mobile internet protocol regional paging network having a visited-domain mobility agent for handling a regional registration of the mobile node visiting a paging area, the mobile node comprising:
-
an idle mode module for periodically providing an idle mode request to the visited-domain mobility agent containing information that the mobile node is entering an idle mode so as to deactivate one or more components for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network; and a time slot paging module for negotiating time slot based paging with the visited-domain mobility agent. - View Dependent Claims (19, 20, 21, 22)

23. A visited-domain mobility agent for handling a regional registration of a mobile node visiting a paging area in a mobile internet protocol regional paging network,
the mobile node having an idle mode module for periodically providing an idle mode request to the visited-domain mobility agent containing information that the mobile node is entering an idle mode so as to deactivate one or more components for energy-saving purposes and reduce active communication with the mobile internet protocol regional paging network, the visited-domain mobility agent having an idle mode reply extension module for negotiating time slot based paging with a time slot paging module of the mobile node.
