Communication apparatus, control method thereof, and storage medium
A communication apparatus includes a sharing unit configured to share a communication parameter for wireless communication with another communication apparatus with the another communication apparatus, a connection unit configured to connect to the another communication apparatus using the communication parameter shared by the sharing unit, a communication unit configured to, after connection with the another apparatus by the connection unit, communicate with the another communication apparatus by utilizing a predetermined function, and a control unit configured to control the communication parameter shared by the sharing unit according to a result of communication by the communication unit utilizing the predetermined function.
1. A communication apparatus comprising:
a receiver configured to receive, from another communication apparatus, service type information indicating a type of service that is executable between the communication apparatus and the another communication apparatus after communication has been established;
at least one processor and a memory storing instructions, that when executed by the at least one processor controls the at least one processor to perform operations comprising:
obtaining a communication parameter for communication with the another communication apparatus;
establishing communication between the communication apparatus and the another communication apparatus using the communication parameter;
searching for the service type information via the communication established based on the obtained communication parameter, wherein the receiver is configured to receive the service type information from the another communication apparatus based on the searching; and
discarding the obtained communication parameter in response to a failure of the search to locate the service type information,
wherein the communication parameter includes identification information of a wireless network, and an encryption method and an authentication method that are used for the wireless network.
2. The communication apparatus according to claim 1 , wherein the obtained communication parameter is discarded in a case where the service type information is received by the receiver but does not include a predetermined type of service.
3. The communication apparatus according to claim 1 , wherein the communication apparatus transmits, to the another communication apparatus, function type information indicating a function of the communication apparatus, and
discards the obtained communication parameter in a case where a failure to transmit the function type information is detected.
4. The communication apparatus according to claim 1 , wherein the communication apparatus obtains a type of the another communication apparatus from the another communication apparatus, and
discards the obtained communication parameter in a case where the obtained type of the another communication apparatus is not a predetermined type.
5. The communication apparatus according to claim 4 , wherein the receiver receives the service type information in a case where the type of the another communication apparatus is the predetermined type.
6. The communication apparatus according to claim 1 , wherein the communication apparatus issues a request for the service type information to the another communication apparatus, and
wherein the receiver receives the service type information from the another communication apparatus as a response to the issued request.
7. The communication apparatus according to claim 1 , wherein the service type information includes at least one of a name of a service, a type of a service, a command for causing the another communication apparatus to execute the service, a name of a function, a type of the function, and a command for causing the another communication apparatus to execute the function.
8. A method for controlling a communication apparatus, the method comprising:
obtaining a communication parameter for establishing communication with another communication apparatus;
establishing communication between the communication apparatus and the another communication apparatus using the communication parameter,
searching for the service type information via the communication established based on the obtained communication parameter, wherein the communication apparatus is configured to receive the service type information from the another communication apparatus based on the searching; and
discarding the obtained communication parameter in response to a failure of the search to locate the service type information,
wherein the communication parameter includes identification information of a wireless network, and an encryption method and an authentication method that are used for the wireless network.
9. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, execute a control method for controlling a communication apparatus, the control method comprising:
obtaining a communication parameter for establishing communication with another communication apparatus;
establishing communication between the communication apparatus and the another communication apparatus using the communication parameter,
searching for the service type information via the communication established based on the obtained communication parameter, wherein the communication apparatus is configured to receive the service type information from the another communication apparatus based on the searching; and
discarding the obtained communication parameter in response to a failure of the search to locate the service type information,
wherein the communication parameter includes identification information of a wireless network, and an encryption method and an authentication method that are used for the wireless network.
10. The communication apparatus according to claim 1 , wherein the service type information includes an identifier usable by the communication apparatus to execute the service with the another communication apparatus.
11. The communication apparatus according to claim 1 , wherein the service type information includes an identifier enabling execution of the service between the communication apparatus and the another communication apparatus.
12. The communication apparatus according to claim 1 , wherein the service type information describes a function being performed between the communication apparatus and the another communication apparatus and an identifier including information enabling the communication apparatus to execute the service type between the communication apparatus and the another communication apparatus.
