Abstract
In transferring a service context during hand-over of a mobile node located in a wireless mesh network, transfer boundaries are set according to positions spaced from an initial Access Point (AP) to which the mobile node is initially connected to, AP types being determined based upon the set transfer boundaries. Prior to hand-over of the mobile node in response to its movement, a service context is transferred to APs arranged in a moving direction of the mobile node based upon context transfer policies according to the determined AP types.
Claims18
A method of transferring a service context during a hand-over of a mobile node in a wireless mesh network, the method comprising:
- setting transfer boundaries according to positions spaced from an initial Access Point (AP) initially connected to the mobile node and determining AP types based upon the set transfer boundaries;
- and
- transferring a service context to APs arranged in a moving direction of the mobile node based upon context transfer policies according to the determined AP types prior to hand-over of the mobile node in response to its movement.
A method of transferring a service context during a hand-over of a mobile node in a Wi-bro network, the method comprising:
- setting transfer boundaries to increase in hop units according to positions from an initial Access Point (AP) initially connected to the mobile node and determining AP types based upon the set transfer boundaries;
- and
- prior to hand-over of the node in response to its movement, transferring a service context to at least one AP subject to transfer selected based upon service context transfer policies according to the AP types.
An Access Point (AP) comprising:
- a mobile node connected thereto during a hand-over in a wireless network;
- and
- service context transfer policies defined according to AP types determined based upon transfer boundaries set to gradually increase according to positions from an initial AP initially connected to the mobile node;
- wherein the AP is adapted to transfer a service context to surrounding APs according to the context transfer policies before hand-over of the mobile node in response to its movement;
- and
- wherein the surrounding APs are arranged in a moving direction of the mobile node.
A system of transferring a service context during a hand-over of a mobile node arranged in a wireless mesh network, the system comprising:
- a plurality of Access Points (APs) adapted to be connected to a mobile node during hand-over in the wireless mesh network, each of the APs having service context transfer policies defined according to AP types based upon transfer boundaries set to gradually increase according to positions from an initial AP initially connected to the mobile node, and adapted to transfer a service context to surrounding APs according to the context transfer policies before hand-over of the mobile node in response to its movement, wherein the surrounding APs are arranged in a moving direction of the mobile node;
- and
- an access router adapted to interface the APs with the Internet;
- wherein the mobile node is adapted to move in the wireless mesh network while changing its connection with the APs.
