Wireless LAN system, communication terminal, LAN control apparatus and QoS control method
First Claim
1. A wireless LAN (Local Area Network) system comprising:
- a communication terminal connectable to a wireless LAN; and
a LAN control apparatus to be connected to said communication terminal via said wireless LAN in such a manner as to be able to exchange communication data with said communication terminal, wherein said communication terminal including policy request means which requests of said LAN control apparatus for a QoS (Quality of Service) management table as a QoS policy to manage QoS of said communication data at a time of establishing connection to said wireless LAN, analyzing/setting means which analyzes said QoS management table sent from said LAN control apparatus in response to a request made by said policy request means and sets QoS setting data of said communication terminal in an updatable manner based on a result of that analysis, and setting-data transmission means which sends said QoS setting data, set by said analyzing/setting means, to said LAN control apparatus, and said LAN control apparatus including table holding means which holds said QoS management table in an updatable manner, table transmission means which sends said QoS management table in response to said request from said communication terminal, policy reconstruction means which updates said QoS setting data, sent from said communication terminal, on said QoS management table to reconstruct said QoS policy, and QoS control means which executes QoS control on said communication data with said communication terminal in accordance with said QoS policy which is determined by said QoS management table.

Abstract
Disclosed is a wireless LAN (Local Area Network) system which overcomes a troublesome operation and process of setting QoS needed for each LAN at the time of using various LANs in a home, an office, countless Hotspots and so forth. The wireless LAN system has a terminal and LAN control section. The terminal has a QoS (Quality of Service) analyzing/setting section which requests of the LAN control section for a QoS management table as a QoS policy to manage QoS of communication data at the time of establishing connection to a wireless LAN, analyzes the table sent from the LAN control section in response to the request, sets QoS setting data based on the result of that analysis, and sends the data to the LAN control section. The LAN control section has a QoS setting DB (Data Base) which holds the table in an updatable manner, and a QoS communication control section which sends the table in response to the request from the terminal, updates the QoS setting data from the communication terminal on the table, and executes QoS control on the communication data with the communication terminal in accordance with the QoS policy.
