Wireless LAN system, wireless LAN access point, handover execution method and program

摘要

Disclosed is a wireless LAN access point which has a detection means for detecting another wireless LAN access point; a handover timing adjustment means which makes a wireless LAN client under the control of the local wireless LAN access point transmit the handover information required to accommodate the other wireless LAN access point and adjust the handover timing with the other wireless LAN access point when it is judged whether or not a handover to the other wireless access point of the wireless LAN client under control can be executed and the handover is executed based on information relating to the other wireless LAN access point detected; and handover execution means for stopping the communication to the wireless LAN client at the adjusted timing.

主权项

1. A wireless LAN system comprising a first wireless LAN access point and a second wireless LAN access point:
wherein said first wireless LAN access point comprises:
a detector that detects said second wireless LAN access point independent of wireless LAN clients;a handover timing adjuster that judges whether or not a handover of the wireless LAN clients under control to said second wireless LAN access point is to be executed independent of the wireless LAN clients based upon information relating to said detected second wireless LAN access point, transmits handover information necessary for accommodation of said wireless LAN clients under control of said first wireless LAN access point to said second wireless LAN access points independent of the wireless LAN clients, said accommodation being performed by said second wireless LAN access point, and adjusts timing of the handover with said second wireless LAN access point independent of the wireless LAN clients when the handover is executed, wherein said handover information includes a timer value of Delivery Traffic Indication Map (DTIM) of said first wireless LAN access point; anda handover execution unit that stops communication to said wireless LAN clients at said adjusted timing independent of the wireless LAN clients; and wherein said second wireless LAN access point comprises:
a handover timing adjuster that makes a response to a request for the handover coming from said first wireless LAN access point, judges whether or not said handover is to be executed independent of the wireless LAN clients, and adjusts timing of the handover with said first wireless LAN access point independent of the wireless LAN clients when the handover is executed; anda handover execution unit that starts communication to said wireless LAN clients at the timing in which said handover is executed based upon said handover information, wherein said first wireless LAN access point comprises a storage that stores information relating to said second wireless LAN access point, wherein said handover timing adjuster judges whether or not the handover of the wireless LAN clients under control to said second wireless LAN access points is to be executed by collating with the information relating to said second wireless LAN access points stored in said storage.
