Wireless LAN communication terminal and communication control method thereof in wireless LAN system for the same

摘要

A wireless LAN communication terminal and its communication control method are provided that make it possible to configure desired security between the terminal and an other-end terminal, without increasing power consumption of the terminals. The wireless LAN communication terminal (103) in a wireless LAN system including an access point (102), if the other-end terminal (101) has connected to the access point 102, acquires from the other-end terminal information about security functions the other-end terminal has and information about a current connection with the access point; compares the security function information and the connection information on the other-end terminal with its own security policy; selects, based on results of the comparisons, either a direct connection (106) with the other-end terminal or a relay connection (105) via the access point so that the security policy is met; and performs communication with the other-end terminal by using the selected connection.

主权项

1. A wireless LAN communication terminal in a wireless LAN (Local Area Network) system including at least one access point, comprising:
an acquisition section that, when an other-end wireless LAN communication terminal on another end of communication has connected to the access point, acquires from the other-end terminal security function information about security functions of the other-end terminal and current connection information about a current connection between the other-end terminal and the access point; a selection section that compares the security function information and the current connection information on the other-end terminal with a security policy of its own terminal and, based on results of the comparisons, selects either a direct connection with the other-end terminal or a relay connection via the access point so that the security policy is met, wherein the relay connection includes the current connection and wherein when the current connection information meets the security policy, the selection section selects the relay connection and, when the current connection information does not meet the security policy, selects the direct connection or the relay connection using one of the security functions of the other-end terminal that meets the security policy; and a communication section that performs communication with the other-end terminal by using a selected connection.
