Abstract
A method and system for distributed roaming in a wireless mesh network are disclosed. Cells are able to track and predict a users movement throughout the network. The user's roaming profile is forwarded to predicted future cells before the user actually enters those cells. When the user enters a new cell, roaming is completed without communication to any other cells. Thus, handoff time is reduced and users may more seamlessly move throughout the network coverage area.
Claims7
A method, comprising:
- determining when a device enters an overlap region when moved from an old cell toward a new cell in a mesh network;
- retrieving a user's roaming profile associated with the device from a router servicing the old cell;
- and
- storing the user's roaming profile in a router servicing the new cell, while the device is located within the overlap region.
1 more element
A network, comprising:
- a plurality of cells, further comprising:
- an old cell in which a device exists;
- a new cell toward which the device moves;
- an overlap region in which the device can be detected by the old cell and the new cell;
- a plurality of routers servicing the plurality of cells, wherein:
- the router servicing the new cell retrieves a user's roaming profile associated with the device from the router servicing the old cell;
- and
- the router servicing the new cell stores the user's roaming profile while the device is in the overlap region.
