Abstract:
1. A method, comprising: determining when a mobile device enters an overlap region when moved from an old cell toward a new cell in a mesh network, the mesh network having a plurality of cells including the old cell and the new cell and a plurality of mobile devices including the mobile device, and each of the plurality of cells being serviced by at least one router of a plurality of routers; retrieving a user's roaming profile associated with the mobile device from a proxy home agent collocated in a router servicing the old cell, wherein a proxy home agent database replicates a permanent home agent database in the mesh network, both the proxy home agent database and the permanent home agent database containing roaming profiles associated with the plurality of mobile devices including the user's roaming profile, and association information of the plurality of mobile devices with the plurality of routers; authorizing the mobile device to associate with the proxy home agent collocated in the router servicing the old cell without querying the permanent home agent for a security association; transferring in a single hop the user's roaming profile from the router servicing the old cell to a router servicing the new cell, while the mobile device is located within the overlap region; updating association information between the mobile device and the routers servicing the old cell and the new cell in the proxy home agent database prior to updating the association information in the permanent home agent database; synchronizing the updated association information between the mobile device and the routers servicing the old cell and new cell in the permanent home agent database; maintaining the proxy home agent with the mobile device while the mobile device is registered in the mesh network; and tracking the mobile device with the proxy home agent by moving the proxy home agent to the router servicing the new cell.
