Wireless LAN system for predicting movement destination of child station and wireless LAN parent station therefor
First Claim
1. A wireless LAN system for predicting movement destination of a child station, which includes the child station and a plurality of parent stations, wherein each of said parent stations has a MAC address and comprises:
- a wireless communication section for conducting communication with the child station, the communication including detecting a handover of said child station from said parent station;
a table control section acquiring a table having the MAC address of each said parent stations that, relative to said parent station, can be a movement destination parent station registered, in response to said wireless communication section detecting the handover of the child station;
a band reserving request signal transmitting section for generating a transmission instruction for transmitting a band reserving request frame to all of said plurality of movement parent stations having their respective MAC address registered in said table movement destination parent station; and
a LAN communication section for receiving the transmission instruction and transmitting the band reserving request frame to the movement destination parent stations via LAN, further comprising;
a local area route information server for providing a route information to each of said parent stations, said route information representing a direction that a child station cannot be moved in relation to said parent station, whereinsaid parent station further comprises a route state determining section for receiving and storing the route information and, based on said stored route information, nullifying a transmission instruction for transmitting a band reserving reguest to the parent station positioned in the direction in which the child station can not be moved.

Abstract
In the wireless LAN system including the child station and parent stations, when each parent station detects handover of the child station during QoS communication through a wireless communication section, a table control section acquires the table where MAC addresses of movement destination parent stations have been registered and the band reserving request signal transmitting section transmits the band reserving request frame to the parent stations through a LAN communication section via Ethernet. The table control section includes a registering means which registers the acquired table, a deleting means which deletes the table and a managing means which updates and manages the table.

11. A wireless LAN parent station for predicting movement destination of a child station, comprising:
-
a wireless communication section for conducting communication with the child station, the communication including detecting a handover of said child station from said parent station; a table control section for acquiring a table having the MAC address of each said parent stations that, relative to said parent station, can be a movement destination parent station registered, in response to said wireless communication section detecting the handover of the child station; a band reserving request signal transmitting section for generating a transmission instruction for transmitting a band reserving request frame to all of said plurality of movement parent stations having their respective MAC address registered in said table movement destination parent station; and a LAN communication section for receiving the transmission instruction and transmitting the band reserving request frame to the movement destination parent stations via LAN, further comprising; a local area route information server for providing a route information to each of said parent stations, said route information representing a direction that a child station cannot be moved in relation to said parent station, wherein said parent station further comprises a route state determining section for receiving and storing the route information and, based on said stored route information, nullifying a transmission instruction for transmitting a band reserving request to the parent station positioned in the direction in which the child station can not be moved.
