Abstract
A mobile internet protocol regional paging networkincludes 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 nodemay include a mobile phone, a pager, or any telecommunications device capable of wireless communicating, including communication over the internet.
