WIRELESS COMMUNICATION METHOD, MOBILE IP TERMINAL, ACCESS POINT, AND INTELLIGENT SWITCH

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication method for smoothly executing switching of access points, and to provide a mobile IP terminal, the access point, and an intelligent switch for the wireless communication method.

SOLUTION: A mobile IP terminal STA1 detects decrease in a communication level via active transmitter-receiver and receives a beacon signal including a paging identifier corresponding to a second access point via a standby side transmitter-receiver of the mobile IP terminal STA1. Then the mobile IP terminal STA1 transmits a bicast request message to the intelligent switch, the message requesting transmission of a packet addressed to the mobile IP terminal STA1 to both first and second transmitter-receivers. Further, the intelligent switch transmits the packet addressed to the mobile IP terminal STA1 to both the first and second transmitter-receivers. When the communication level is decreased in either of the first and second transmitter-receivers, the mobile IP terminal STA1 transmits a bicast stop request message for requesting the stop of transmission to the transmitter-receiver whose communication level is decreased.
