Method and apparatus for transferring information on station in wireless mesh network
First Claim
1. A method for a mesh access point to transfer information on a station in a wireless mesh network comprising a plurality of mesh access points and a mesh portal which connects the wireless mesh network to an external network via a wired network, the method comprising:
- (a) generating, by a processor, a disassociation message indicating that the station is disassociated from the mesh access point, when a disassociation of the station is detected; and
(b) requesting the mesh portal designated as a root node in a tree structure formed using a proactive routing protocol to insert the disassociation message into a message regularly broadcasted in order to maintain the tree structure by the mesh portal,wherein the wireless mesh network uses a hybrid wireless mesh protocol (HWMP) including an ad hoc on-demand distance vector (AODV) routing protocol, andwherein the message regularly broadcasted by the mesh portal includes an address of the station coupled with an address of the mesh access point.

Abstract
A method and apparatus of transferring information on a station to other nodes in a wireless mesh network if the station is associated in or disassociated from a mesh access point are provided. The apparatus includes detection unit which detects a disassociation or association of the station, a message generation unit which generates a disassociation message or an association message indicating that the station is associated in or disassociated from the mesh access point, a requesting unit which transmits the message to a root node in a tree structure formed using a proactive routing protocol, and a message transmission unit which broadcasts the received message.

10. A method for a mesh portal designated as a root node to transfer data in a wireless mesh network comprising a plurality of mesh access points and a mesh portal which connects the wireless mesh network to an external network via a wired network, wherein nodes form a tree structure through a proactive routing protocol in the wireless mesh network, the method comprising:
-
(a) determining, by a processor, whether a message received from a mesh access point is a disassociation message or an association message of a station; and (b) selectively inserting the message received into a message regularly broadcasted in order to maintain the tree structure by the mesh portal based on a determined result, wherein the wireless mesh network uses a wireless mesh protocol (HWMP) including an ad hoc on-demand distance vector (AODV) routing protocol, and wherein the message regularly broadcasted by the mesh portal includes an address of the station coupled with an address of the mesh access point when the message received from the mesh access point is determined to be a disassociation message or an association message of the station. - View Dependent Claims (11)
