Abstract
A radio wave generation device transmits and receives packets by radio waves. The radio wave generation device determines, based on sensor data acquired from a server, whether a wireless terminal has newly entered a floor subject to position determination. When it is determined that the wireless terminal has newly entered the floor subject to position determination, the radio wave generation device performs association of a MAC address of a floor entry terminal with an IP address, the floor entry terminal being the wireless terminal determined to have newly entered the floor subject to position determination. The radio wave generation device performs the association by transmitting a packet requesting a response from the floor entry terminal.
Claims3
A radio wave generation device comprising:
- a memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- transmit and receive packets by radio waves;
- when at least one media access control (MAC) address included in sensor data acquired from a server is a MAC address that is not present in an address resolution protocol (ARP) table, determine that a wireless terminal has newly entered a floor subject to position determination;
- when it is determined that the wireless terminal has newly entered the floor subject to position determination, perform association of a MAC address of a floor entry terminal with an internet protocol (IP) address, the floor entry terminal being the wireless terminal determined to have newly entered the floor subject to position determination;
- perform the association by transmitting a packet requesting a response from the floor entry terminal;
- unicast an ARP request packet requesting a response from the floor entry terminal;
- generate a transmission destination list in which each of a plurality of IP addresses in a subnetwork in which the radio wave generation device belongs is associated with the MAC address of the floor entry terminal;
- and
- unicast an ARP request packet requesting a response from the floor entry terminal in a sequence based on the transmission destination list.

A radio wave generation device comprising:
- a memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- transmit and receive packets by radio waves;
- acquire setting information from a server;
- generate a position determination terminal table for a wireless terminal subject to position determination based on the setting information;
- acquire sensor data from the server;
- when at least one media access control (MAC) address included in the sensor data acquired from the server is a MAC address that is not present in an address resolution protocol (ARP) table, determine that a wireless terminal has newly entered a floor subject to position determination;
- when it is determined that the wireless terminal has newly entered the floor subject to position determination, perform association of MAC address of a floor entry terminal with an internet protocol (IP) address, the floor entry terminal being the wireless terminal determined to have newly entered the floor subject to position determination, wherein
- perform the association by transmitting a packet requesting a response from the floor entry terminal, and
- update the position determination terminal table so that the floor entry terminal for which the association has been performed becomes the wireless terminal subject to the position determination;
- unicast an ARP request packet requesting a response from the floor entry terminal;
- generate a transmission destination list in which each of a plurality of IP addresses in a subnetwork in which the radio wave generation device belongs is associated with the MAC address of the floor entry terminal;
- and
- unicast an ARP request packet requesting a response from the floor entry terminal in a sequence based on the transmission destination list.
12 more elements
An address association method comprising:
- transmitting and receiving packets by radio waves;
- when at least one media access control (MAC) address included in sensor data acquired from a server is a MAC address that is not present in an address resolution protocol (ARP) table, determining that a wireless terminal has newly entered a floor subject to position determination;
- and
- when it is determined that the wireless terminal has newly entered the floor subject to position determination, performing association of a MAC address of a floor entry terminal with an internet protocol (IP) address, the floor entry terminal being the wireless terminal determined to have newly entered the floor subject to position determination,
- wherein a packet requesting a response from the floor entry terminal is transmitted when the association is performed, and
- wherein the method further comprises:
- unicasting an ARP request packet requesting a response from the floor entry terminal;
- generating a transmission destination list in which each of a plurality of IP addresses in a subnetwork in which a radio wave generation device belongs is associated with the MAC address of the floor entry terminal;
- and
- unicasting an ARP request packet requesting a response from the floor entry terminal in a sequence based on the transmission destination list.
