Communication apparatus, control method, and storage medium

A method for controlling a communication apparatus having

• a first wireless communication function of carrying out, at a first communication interface, first wireless communication by a first wireless communication method conforming to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series;
• and
• a second wireless communication function of carrying out, at a second communication interface, second wireless communication by a second communication method in compliance with the Fifth-generation Mobile Communication System (5G) formulated by the Third Generation Partnership Project (3GPP), and
• the method comprising:
• obtaining, by the second communication method, country information identifying a country from a base station that performs the 5G communication using a band of 6 gigahertz (GHz) or higher, wherein the country information identifying the country in which the base station performing the 5G communication using the band of 6 GHz or higher is located,
• determining, based on the obtained country information, whether a country in which the communication apparatus is located has changed to a different country or not,
• determining, in a case where the country in which the communication apparatus is located is determined to have changed, whether a wireless channel that is in use in the first wireless communication by the first wireless communication method and an upper limit on transmission power are compliant with a communication regulation of the different country or not,
• performing control for continuing the first wireless communication using the first wireless communication function in a case where the wireless channel and the upper limit are determined to be compliant with the communication regulation of the different country and for disabling the first wireless communication function in a case where the wireless channel and the upper limit are determined to be not compliant with the communication regulation of the different country,
• changing, after disabling the first wireless communication function, a useable channel and/or the upper limit on the transmission power, for compliance with the communication regulation of the different country, and
• enabling the first wireless communication function after completion of the changing,
• wherein country information obtained from a base station that performs the 5G communication using a band lower than 6 GHz is not used for the determining of whether the country in which the communication apparatus is located has changed.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of a communication apparatus, the communication apparatus having:

• a first wireless communication function of carrying out, at a first communication interface, first wireless communication by a first wireless communication method conforming to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series;
• and
• a second wireless communication function of carrying out, at a second communication interface, second wireless communication by a second communication method in compliance with the Fifth-generation Mobile Communication System (5G) formulated by the Third Generation Partnership Project (3GPP), and
• the control method comprising:
• obtaining, by the second communication method, country information identifying a country from a base station that performs the 5G communication using a band of 6 gigahertz (GHz) or higher, wherein the country information identifying the country in which the base station performing the 5G communication using the band of 6 GHz or higher is located,
• determining, based on the obtained country information, whether a country in which the communication apparatus is located has changed to a different country or not,
• determining, in a case where the country in which the communication apparatus is located is determined to have changed, whether a wireless channel that is in use in the first wireless communication by the first wireless communication method and an upper limit on transmission power are compliant with a communication regulation of the different country or not,
• performing control for continuing the first wireless communication using the first wireless communication function in a case where the wireless channel and the upper limit are determined to be compliant with the communication regulation of the different country and for disabling the first wireless communication function in a case where the wireless channel and the upper limit are determined to be not compliant with the communication regulation of the different country,
• changing, after disabling the first wireless communication function, a useable channel and/or the upper limit on the transmission power, for compliance with the communication regulation of the different country, and
• enabling the first wireless communication function after completion of the changing,
• wherein country information obtained from a base station that performs the 5G communication using a band lower than 6 GHz is not used for the determining of whether the country in which the communication apparatus is located has changed.
