Wireless communication system, wireless LAN access point and settings confirmation/change method used therefor
View Patent ↗There is provided a wireless LAN access point capable of confirming and changing the setting using the IP communication for a target wireless LAN access point positively even when the IP address of the wireless LAN access point is forgotten. The wireless LAN access point, upon receipt of a probe request, transmits a probe response while at the same time starting to transmit a beacon frame required to be periodically transmitted. The wireless LAN access point starts the DHCP server therein at the same time that the process of associating the wireless LAN station is started. The DHCP server operates only for the wireless interface of the wireless LAN access point and the wireless LAN station associated by use of the maintenance SSID. The wireless LAN access point, upon complete association of the wireless LAN station with the local access point, leases the IP address to the wireless LAN station from the DHCP server in the particular local access point.
1. A wireless communication system for conducting wireless communication, the wireless communication system comprising:
a wireless LAN (local area network) terminal; and
a wireless LAN access point in wireless communication with the wireless LAN terminal, the wireless LAN access point comprising means for releasing an IP (Internet protocol) address to the wireless LAN terminal that was associated with the wireless LAN access point by use of a maintenance SSID (service set identifier) set in advance, the maintenance SSID comprising a number unique to the wireless LAN access point,
wherein the means for releasing an IP address comprises a DHCP (Dynamic Host Configuration Protocol) server that executes a DHCP process and is provided within the wireless LAN access point,
wherein the DHCP server is adapted or arranged to execute the DHCP process only for the wireless LAN terminal that was associated with the wireless LAN access point by use of the maintenance SSID,
wherein the wireless LAN access point is adapted or arranged to, upon receipt of a probe signal including the maintenance SSID from the wireless LAN terminal, start transmission of a beacon frame required to be transmitted periodically and then a process to associate the wireless LAN terminal with the wireless LAN access point,
wherein the maintenance SSID is at least one of a MAC (media access control) address and a serial number of the wireless LAN access point, and
wherein the wireless LAN access point is adapted or arranged to prevent data that were sent from the wireless LAN terminal from leaking into a network.
2. The wireless communication system according to claim 1 ,
wherein the wireless LAN access point comprises at least one of a wireless LAN access point in a system with a wireless LAN switch and a wireless LAN access point adapted for a mesh network having no wire line.
3. A wireless LAN access point for conducting wireless communication with a wireless LAN (local area network) station, the wireless LAN access point comprising:
means for communicating with the wireless LAN station; and
means for releasing an IP address to the wireless LAN station that was associated with the wireless LAN access point by use of a maintenance SSID (service set identifier) set in advance, the maintenance SSID comprising a number unique to the wireless LAN access point,
wherein the means for releasing an IP address comprises a DHCP (Dynamic Host Configuration Protocol) server that executes a DHCP process and is provided within the wireless LAN access point,
wherein the DHCP server is adapted or arranged to execute the DHCP process only for the wireless LAN station that was associated with the wireless LAN access point by use of the maintenance SSID,
wherein the wireless LAN access point is adapted or arranged to start transmission of a beacon frame required to be transmitted periodically and then a process to associate the wireless LAN station with the wireless LAN access point upon receipt of probe signal including the maintenance SSID from the wireless LAN station,
wherein the maintenance SSID comprises at least one of a MAC (media access control) address and a serial number of the wireless LAN access point, and
wherein the wireless LAN access point is adapted or arranged to prevent data that were sent from the wireless LAN terminal from leaking into a network.
4. The wireless LAN access point according to claim 3 , wherein the wireless LAN access point comprises at least one of a wireless LAN access point in a system with a wireless LAN switch and a wireless LAN access point adapted for a mesh network having no wire line.
5. A setting content confirmation/change method used for a wireless communication system to conduct wireless communication between a wireless LAN station and a wireless LAN (local area network) access point, the method comprising:
executing by the wireless LAN access point, a process of releasing an IP (Internet protocol) address to the wireless LAN station that was associated with the wireless LAN access point by use of a maintenance SSID (service set identifier) set in advance, the maintenance SSID comprising a number unique to the wireless LAN access point; and
communicating wirelessly between the wireless LAN station and the wireless LAN access point,
wherein the means for releasing an IP address comprises a DHCP (Dynamic Host Configuration Protocol) process that is executed within the wireless LAN access point,
wherein the DHCP process is executed only for the wireless LAN station that was associated with the wireless LAN access point by use of the maintenance SSID,
wherein the wireless LAN access point, upon receipt of a probe signal including the maintenance SSID from the wireless LAN station, starts transmission of a beacon frame required to be transmitted periodically and then a process to associate the wireless LAN station with the wireless LAN access point,
wherein the maintenance SSID comprises at least one of a MAC (media access control) address and a serial number of the wireless LAN access point, and
wherein the wireless LAN access point is adapted or arranged to prevent data that were sent from the wireless LAN terminal from leaking into a network.
6. The setting content confirmation/change method according to claim 5 ,
wherein the wireless LAN access point comprises at least one of a wireless LAN access point in a system with a wireless LAN switch and a wireless LAN access point adapted for a mesh network having no wire line.
