Wireless communication terminal with an rfid module, wireless communication system, wireless communication method, and a device storing a program

A wireless communication system, comprising:

• a wireless communication terminal with an RFID module;
• and
• an external terminal,
• wherein the wireless communication terminal with the RFID module comprises:
• a wireless communication module configured to operate in one of a first state in which wireless communication with the external terminal is performed through a layer higher than a data link layer and a second state in which the wireless communication with the external terminal is not performed through the layer higher than the data link layer or electric power supply used to perform wireless communication with the external terminal through the data link layer is not performed, the wireless communication module wirelessly transmitting transmission target data when operating in the first state;
• a power supply unit configured to perform the electric power supply to the wireless communication module;
• a power supply control unit configured to perform power supply control of the power supply unit;
• a control unit configured to perform control such that parameters of the layer higher than the data link layer is set to parameters of the wireless communication module;
• an RFID module configured to store wireless communication setting information which is used for the external terminal to perform wireless communication with the wireless communication module and data presence/absence information indicating presence/absence of the transmission target data, the RFID module detecting a read request to read the wireless communication setting information transmitted from the external terminal, the RFID module wirelessly transmitting the wireless communication setting information to the external terminal that has transmitted the read request in response to the read request when the read request is detected;
• and
• a data update unit configured to update the data presence/absence information stored in the RFID module,
• wherein when the read request is detected and the data presence/absence information indicating the presence of the transmission target data is stored while the wireless communication module is operating in the second state, the RFID module outputs a signal to one of the control unit and the power supply control unit which causes a state of the wireless communication module to transition from the second state to the first state, and
• the external terminal comprises:
• a tag reading unit configured to transmit the read request to the RFID module, and receives the wireless communication setting information transmitted in response to the read request, and
• a terminal wireless communication module configured to perform wireless communication with the wireless communication module using the wireless communication setting information received by the tag reading unit.

A wireless communication method, comprising:

• a wireless communication step of wirelessly transmitting transmission target data when a wireless communication module operates in a first state, the wireless communication module being configured to operate in one of the first state in which wireless communication with an external terminal is performed through a layer higher than a data link layer and a second state in which the wireless communication with the external terminal is not performed through the layer higher than the data link layer or electric power supply used to perform wireless communication with the external terminal through the data link layer is not performed;
• a power supply control step of controlling power supply of a power supply unit configured to perform the electric power supply to the wireless communication module;
• a control step of setting parameters of the layer higher than the data link layer to parameters of the wireless communication module;
• a step of wirelessly transmitting the wireless communication setting information to the external terminal that has transmitted a read request in response to the read request when the read request to read the wireless communication setting information transmitted from the external terminal is detected by an RFID module that is configured to store wireless communication setting information which is used for the external terminal to perform wireless communication with the wireless communication module and data presence/absence information indicating presence/absence of the transmission target data;
• and
• a step of outputting a signal by the RFID module to one of the control unit and the power supply control unit when the read request is detected and the data presence/absence information indicating the presence of the transmission target data is stored while the wireless communication module is operating in the second state, the signal causing a state of the wireless communication module to transition from the second state to the first state.

A device storing a program to execute:

• a wireless communication step of wirelessly transmitting transmission target data when a wireless communication module operates in a first state, the wireless communication module being configured to operate in one of a first state in which wireless communication with an external terminal is performed through a layer higher than a data link layer and a second state in which the wireless communication with the external terminal is not performed through the layer higher than the data link layer or electric power supply used to perform wireless communication with the external terminal through the data link layer is not performed;
• a power supply control step of controlling power supply of power supply unit configured to perform the electric power supply to the wireless communication module;
• a control step of setting parameters of the layer higher than the data link layer to parameters of the wireless communication module;
• a step of wirelessly transmitting the wireless communication setting information to the external terminal that has transmitted a read request in response to the read request when the read request to read the wireless communication setting information transmitted from the external terminal is detected by an RFID module that is configured to store wireless communication setting information which is used for the external terminal to perform wireless communication with the wireless communication module and data presence/absence information indicating presence/absence of the transmission target data;
• and
