Wireless LAN system, access point management apparatus, access point, wireless LAN control method, and computer program

摘要

An object of the present invention is to reduce the time required for reacquiring an IP address at the time of handover without requiring control on the wireless terminal side. A wireless LAN system according to an embodiment includes a first AP and a second AP having a function as a DHCP server, and an AP management apparatus capable of communicating with the first AP and the second AP. A DHCP Request packet destined for the first AP, which is transmitted when the wireless attribution is changed from the first AP to the own device, is transferred to the AP management device, and the AP management device transmits the DHCP Request packet transmitted from the second AP. The first AP generates a DHCP Nak packet for the wireless terminal in response to the DHCP Request packet transmitted from the AP management apparatus and transmits the DHCP Nak packet to the AP management apparatus. The transmitted DHCP Nak packet is transferred to the second AP, and the second AP transfers the DHCP Nak packet transmitted from the AP management apparatus to the wireless terminal.
