Communication apparatus, communication method, and program

Abstract

A communication apparatus includes an acquisition unit that acquires identification information from a first different communication apparatus, a determination unit that determines whether the acquired identification information is first identification information, a reception unit that receives, from the first different communication apparatus, a predetermined request to connect a second different communication apparatus to a wireless network generated by the communication apparatus, and a providing unit that, in a case where the identification information is the first identification information, provides the second different communication apparatus with a communication parameter for connecting to the wireless network in response to receipt of the predetermined request.

What is claimed is: 
     
         1 . A communication apparatus, comprising:
 an acquisition unit configured to acquire identification information from a first different communication apparatus;   a determination unit configured to determine whether the identification information acquired by the acquisition unit is first identification information;   a reception unit configured to receive, from the first different communication apparatus, a predetermined request to connect a second different communication apparatus to a wireless network generated by the communication apparatus; and   a providing unit configured to, in a case where the identification information is the first identification information, provide the second different communication apparatus with a communication parameter for connecting to the wireless network in response to receipt of the predetermined request,   wherein in a case where the identification information is not the first identification information, the second different communication apparatus is not provided with the communication parameter even upon receipt of the predetermined request.   
     
     
         2 . The communication apparatus according to  claim 1 , further comprising a display unit configured to display at least one of the first identification information or second identification information different from the first identification information. 
     
     
         3 . The communication apparatus according to  claim 2 , wherein the display unit displays the first identification information or the second identification information as a QR code® or a bar code. 
     
     
         4 . The communication apparatus according to  claim 2 , wherein when the identification information acquired by the acquisition unit is the first identification information or the second identification information, the providing unit provides the first different communication apparatus with the communication parameter for connecting to the wireless network. 
     
     
         5 . The communication apparatus according to  claim 1 , further comprising a generation unit configured to generate a wireless network and periodically transmit a beacon. 
     
     
         6 . The communication apparatus according to  claim 1 , wherein the first identification information includes at least any one of information of a public key of the communication apparatus, information of a certificate of the communication apparatus, or an identifier specific to the first different communication apparatus. 
     
     
         7 . The communication apparatus according to  claim 1 , further comprising a control unit configured to, when the identification information acquired by the acquisition unit is the first identification information, store information of the first different communication apparatus in a storage unit. 
     
     
         8 . The communication apparatus according to  claim 1 , wherein when the identification information acquired by the acquisition unit is not the first identification information, the providing unit does not provide the second different communication apparatus with the communication parameter for connecting to the wireless network. 
     
     
         9 . The communication apparatus according to  claim 1 , wherein when the communication parameter for connecting to the wireless network is requested by the first different communication apparatus, the acquisition unit acquires the identification information. 
     
     
         10 . The communication apparatus according to  claim 1 , wherein when the first identification information or the second identification information is acquired from the first different communication apparatus, the first communication apparatus changes setting of a network generated by the communication apparatus. 
     
     
         11 . A communication method implemented by a communication apparatus, the communication method comprising:
 a first acquisition step of acquiring identification information from a first different communication apparatus;   a determination step of determining whether the identification information is first identification information;   a reception step of receiving, from the first different communication apparatus, a predetermined request to connect a second different communication apparatus to a wireless network generated by the communication apparatus; and   a providing step of, in a case where the identification information is the first identification information, the second different communication apparatus with a communication parameter for connecting to the wireless network in response to receipt of the predetermined request,   wherein in a case where the identification information is not the first identification information, the second different communication apparatus is not provided with the communication parameter even upon receipt of the predetermined request.   
     
     
         12 . The communication method according to  claim 11 , comprising:
 an input step of inputting a QR code® including the identification information by capturing an image of the QR code® by the first different communication apparatus;   a transmission step of transmitting the identification information included in the QR code® from the first different communication apparatus to the communication apparatus; and   a second acquisition step of acquiring the communication parameter from the communication apparatus by the first different communication apparatus in response to transmission of the identification information.   
     
     
         13 . The communication method according to  claim 11 , further comprising a requesting step of making the predetermined request to the communication apparatus by the first different communication apparatus. 
     
     
         14 . A storage medium storing computer executable instructions causing a communication apparatus to implement a communication method, the communication method comprising:
 acquiring identification information from a first different communication apparatus;   determining whether the acquired identification information is first identification information;   receiving, from the first different communication apparatus, a predetermined request to connect a second different communication apparatus to a wireless network generated by the communication apparatus; and   providing, in a case where the identification information is the first identification information, the second different communication apparatus with a communication parameter for connecting to the wireless network in response to receipt of the predetermined request, and   wherein in a case where the identification information is not the first identification information, the second different communication apparatus is not provided with the communication parameter even upon receipt of the predetermined request.
