A position information relay device interposed between a network device and an apparatus includes: a position information recognizer which recognizes position information of the apparatus; and a position information relay which receives a communication packet transmitted by the apparatus to the network device, includes the position information in the communication packet received, and transmits the communication packet including the position information to the network device.

A threshold value calculation device includes: a device state acquirer that acquires a device state of a first device provided in a facility in which a home network is installed during a first period; an occupancy state determiner that determines an occupancy state by people in the facility during the first period based on information acquired from a second device in the facility; a communication log collector that collects a communication log; and a learner that calculates a threshold value for the communication transmitted and received by the first device during a second period that is a period after the first period. The learner calculates the threshold value for each of combinations of one or more states of the first device and one or more states of the people.

A terminal includes: a communicator that wirelessly performs encrypted communication with an access point; a processor; and a memory that stores at least one program executed by the processor and a key management table for storing a group key for the encrypted communication. The processor performs: acquiring the group key from the access point and storing the group key acquired in the key management table as a first group key; receiving a broadcast packet encrypted by the access point via the communicator; making a first determination as to whether the broadcast packet received is decryptable by using the first group key; and when it is determined, in the first determination, that the broadcast packet is not decryptable by using the first group key, generating information indicating that the first group key needs to be updated.
