Problems solved by technology

Thus, after the object device transmits and receives connection information of the wireless LAN via NFC communication and connects with the wireless LAN, the object device recognizes that the desired communication service cannot be performed
Due to this, although the connection process of the wireless LAN is performed, in the case of attempting to execute the service discovery protocol after the connection using the wireless LAN, it may not be possible to perform the desired communication service with the connected communication partner.
Unnecessary wireless LAN connection processing may occur

[0036] refer to Figure 8 The flow chart of the figure is used to explain the operation procedure of the smartphone 101 according to the first embodiment.

[0037] Figure 8 The flow chart of is showing the operation procedure of the smartphone 101 in the case where the smartphone 101 is brought close to the digital television 102 and in the case where the smartphone 101 is brought close to the printer 103 by the user's operation.

[0038] In a case where approach of the NFC communication unit 309 of the digital television 102 is detected, the NFC communication control unit 510 of the smartphone 101 establishes communication using NFC with the digital television 102 (S801). Then, the control unit 205 of the smartphone 101 transmits a service information acquisition request message to the digital television 102 via the NFC communication unit 208 (S802). The service information acquisition request message in this case is a message requesting (requesting to be sent by the oppos...

[0055] In the first embodiment, a method of sharing service information between devices by NFC communication using a relay device has become a method of transmitting service-related information from one device to other devices by two NFC communications. An embodiment has been exemplified in which the relay device notifies the counterpart device of the second NFC communication of the service provided by the counterpart device of the first NFC communication and executes the service between the devices. Hereinafter, as a second embodiment, a method of transmitting service information through three NFC communications is exemplified. The structure and flowchart of the communication system in this embodiment are the same as those of the first embodiment.

[0056] In the following, refer to Figure 10An example of a communication sequence between the smartphone 101, the digital television 102, and the printer 103 will be described in detail. exist Figure 10 In this, first, NFC co...

Abstract

The invention relates to a communication device and a control method for the communication device. The communication device includes: communication means for performing wireless communication using a first communication scheme; first receiving means for receiving from a first other communication device by using a communication means using a second communication scheme different from that of the first other communication device. . First information related to communication processing executable through wireless communication; second receiving means for receiving from the second other communication device by using the communication means the information that is executable through wireless communication with the second other communication device using the second communication scheme second information related to the communication process of the communication device; and sending means for transmitting, by using the communication means, connection parameters required for performing wireless communication between the first other communication device and the second other communication device using the second communication scheme and information from the first other communication device. A request from one other communication device for communication processing indicated by the first information is sent to a second other communication device.

Description

technical field [0001] The present invention relates to communication technology. Background technique [0002] In recent years, for mobile phones, short-distance wireless communication such as NFC (Near Field Communication), IrDA (Infrared Data Association), or TransferJet (registered trademark) has begun to be used. For example, in a case where a user only performs an operation to bring devices closer to each other, short-distance wireless communication is used to establish a one-to-one correspondence communication path, and data can be transmitted and received between the above devices. Also, there is a technique of switching such short-distance wireless communication to a different wireless communication scheme such as wireless LAN (IEEE 802.11 series) or Bluetooth (registered trademark) (Japanese Patent Laid-Open No. 2011-193474). [0003] Furthermore, there is a technique of transmitting and receiving connection information of a short-distance wireless communication s...
