[0037]
FIG. 6 is a sequence diagram illustrating processing of the entire wireless communication system.
[0038]
In FIG. 6, first, a Bluetooth access point (hereinafter abbreviated as BAP) 123 makes an inquiry (Inquiry) to surrounding client terminals (devices). The client terminal that has received the inquiry signal from the BAP 123 makes an inquiry response to the BAP 123. At the same time, the BID and the device class, which are the IDs of the client terminals, are included in the response parameters of the inquiry response inquiry message.
[0039]
The BAP 123 creates the device class management table shown in FIG. 5 in response to receiving the inquiry response from the client terminal. The BAP 123 updates the contents of the device class management table every time there is an inquiry response from a plurality of client terminals. When the creation of the device class management table is completed, the BAP 123 transmits device class information corresponding to the device class management table to the host terminal 100 via the MAP 120.
[0040]
Next, in order for the client terminal to connect to the BAP 123, a connect request is transmitted to the BAP 123. The client terminal completes the connection with the BAP 123 through a connection phase including authentication and the like (Connected). Subsequently, the client terminal transmits a host connection request to the host terminal 100 via the BAP 123. At this time, the parameter of the host connection request includes CID and User representing the user name as an ID for identifying the link. Subsequently, the BAP 123 transmits a connection request from the client terminal to the MAP 120, and accordingly, the MAP 120 transmits a connection request from the client terminal to the host terminal 100. In this case, BID, CID, and User (user name) can be considered as parameters included in the connection request.
[0041]
When the host terminal 100 that has received the connection request for the client terminal from the MAP 120 identifies that the client terminal is a device capable of remote control based on the device class management table, the service request from the client terminal will be transmitted in the future. Set to interpret as remote control signal. The host terminal 100 transmits a connection response to the client terminal via the MAP 120 and the BAP 123. At this point, the communication path between the client terminal and the host terminal is in an “Opened” state, and the client terminal operates as a device capable of remote control operation.
[0042]
Next, as a typical example of the remote control operation in the client terminal, consider a case where conference materials are downloaded to the client terminal. The remote control command in this remote control operation is realized only by the remote control command without using a file transfer protocol such as HTTP (Hyper Text Transfer Protocol) or FTP (File Transfer Protocol).
[0043]
First, the client terminal transmits a material list request command to the host terminal 100 via the BAP 123 and the MAP 120 in order to obtain a list of all conference materials stored in the host terminal 100. Upon receiving the document list request command, the host terminal 100 creates a list of all conference materials storing user names and document attributes in a structured document language such as XML (Extensible Markup Language), and requests the document list. Is transmitted to the client terminal via the MAP 120 and the BAP 123 as a response to the material list. The method for creating the material list will be described later.
[0044]
When the client terminal receives the material list from the host terminal 100, the client terminal displays the material list on the display unit of the client terminal, and makes a request for downloading the material data selected by the user from the displayed material list to the host terminal 100. The document download request command is transmitted from the client terminal to the host terminal 100 via the BAP 123 and the MAP 120.
[0045]
The host terminal 100 transmits the material data to the client terminal via the MAP 120 and the BAP 123 according to the material data download request command transmitted from the client terminal. In addition, regarding the download request of the material data from the client terminal to the host terminal 100, the material attribute indicating whether or not the client terminal has permitted the download authority is set to be disabled (the download authority is not permitted). When a download request is made, a command is not requested to the host terminal 100, but a rejection is made within the client terminal (the user does not accept an operation of a download request for material data).
[0046]
FIG. 7 is a view showing a user interface (hereinafter abbreviated as UI) screen of the material list creation method described above, and is a view showing a material data registration screen (material attribute setting screen) when the material is stored in the host terminal 100. is there.
[0047]
In FIG. 7, the material is registered through the material data registration screen 700 shown in FIG. 7 displayed on the display unit 109 of the host terminal 100. On the document data registration screen 700, a document data name 701 indicating the name of the document data, a user name 702 indicating the owner of the document, an access management check box 703, a create button 704, and a cancel button 705 are displayed. Further, the access management check box 703 displays an area where only users, the same group, other groups, and specific users can be permitted access.
[0048]
In the access management check box 703 of the document data registration screen 700, the document attribute authority (permitted / unpermitted) is set to permit / deny browsing, permit / deny download, permit / deny writing, etc. It is possible to register. When the creation button 704 is pressed on the material data registration screen 700, material attribute information described in the structured language shown in FIG. 8 is generated. Further, when a cancel button 705 is pressed on the document data registration screen 700, the screen is switched to another screen.
[0049]
FIG. 8 is a diagram showing material attribute information when conference material is stored in the host terminal 100.
[0050]
In FIG. 8, material attribute information is described in a structured language.
[0051]
FIG. 9 is a diagram showing an attribute list of all conference material data stored in the host terminal 100.
[0052]
In FIG. 9, the attribute list of all meeting material data is generated from the material attribute information of each material data created in FIG. By using the structured language shown in the figure, data attributes (permission / non-permission of browsing of document data to the user, permission / non-permission of downloading) in the system part (via the application) that is not visible to the user on the client terminal. It is possible to determine whether or not access to the material is permitted.
[0053]
As described above, according to the present embodiment, in the wireless communication conference system, according to the device class of the client terminal (whether it is a PDA or a mobile phone), that is, according to the storage capability and display capability of the client terminal, By enabling the client terminal to operate in the remote control operation mode, even when the client terminal is not equipped with the same application as the host terminal 100, the application of the host terminal 100 can be operated by the remote control operation of the client terminal. There is an effect. Further, since the amount of data transmitted and received in the wireless data communication of the client terminal can be reduced by remote control operation, there is an effect that the power required for the wireless data communication can be reduced and power saving can be realized.
[0054]
Further, since the host terminal 100 can know the attribute of the client terminal (whether or not the remote controller can be operated) by the notification from the BAP 123 based on the device inquiry to the client terminal by the BAP 123 before the client terminal is connected, the client terminal Even when a client terminal connection request is made from the host terminal side as well as the connection from the host terminal 100 to the host terminal 100, the specification is not so that the client terminal can operate as a remote controller before the client terminal is connected to the host terminal 100 Can be determined without adding special processing, and there is a specific effect that serviceability can be improved.
[0055]
In addition, regarding the downloading of conference materials to client terminals, by including the document attribute information in the document list, a download request is issued for documents that have unauthorized document attributes (download not permitted). Even if it is performed, the download request can be rejected by judgment inside the client terminal, so that it is possible to prevent unnecessary radio wave radiation, and both the client terminal and the host terminal 100 can be used from the viewpoint of security. Therefore, it is possible to perform a security check, and there is a specific effect that the security of the system can be improved.
[0056]

FIG. 10 is a flowchart showing the processing of the BAP 123. The processing shown in this flowchart is executed by the CPU control unit 126 of the BAP 123 based on a program.
[0058]
In FIG. 10, first, the BAP 123 waits for a Bluetooth connection request from the client terminal (step S701). When the BAP 123 receives a Bluetooth connection request from the client terminal, the BAP 123 acquires a device class included as a parameter of the Bluetooth connection request, and creates a device class management table shown in FIG. 5 (step S702). Next, the BAP 123 determines whether or not the device class of the client terminal that has made the Bluetooth connection request is a PDA or a mobile phone (step S703).
[0059]
If it is determined that the device class is a PDA or a mobile phone, the BAP 123 turns on the remote control attribute of the device class management table (step S704). On the other hand, if it is determined that the device class is not a PDA or a mobile phone, the BAP 123 turns off the remote control attribute of the device class management table (step S705).
[0060]
Next, the BAP 123 completes the connection with the client terminal by executing a connection control sequence for connecting with the client terminal (step S706). Next, the BAP 123 determines whether or not the number of connected devices has reached the upper limit (step S707). If it is determined that the number of connected devices has not reached the upper limit, the BAP 123 returns to the process of step S701. On the other hand, when the number of connected devices is less than the upper limit, the BAP 123 waits for a connection request from the next client terminal, and when the number of connected devices reaches the upper limit, the connection from the specific client terminal is rejected. (Step S708), the process is terminated.
[0061]
FIG. 11 is a flowchart showing processing of the host terminal 100. The processing shown in this flowchart is executed by the CPU control unit 101 of the host terminal 100 based on a program.
[0062]
In FIG. 11, first, the host terminal 100 waits for a connection request from the MAP 120 (step S801). If it is determined that a connection request has been received from the MAP 120, the host terminal 100 acquires the device class of the client terminal from the MAP 120, and determines whether the device class is a PDA or a mobile phone (step S802).
[0063]
If it is determined that the device class is a PDA or a mobile phone, the host terminal 100 regards the client terminal as a device that can perform a remote control operation, and sets a remote control service for the client terminal (the client terminal is a PDA or a mobile phone). Even when the storage capability and display capability are small, it is possible to receive the same service as a PC with high storage capability and display capability by compressing and transmitting data from the host terminal 100 with the client terminal set in the remote control operation mode. Setting) (step S803), and the process is terminated.
[0064]
FIG. 12 is a sequence diagram showing processing of the entire wireless communication conference system.
[0065]
In FIG. 12, the client terminal transmits to the BAP 123 a BID that is an ID for identifying a Bluetooth client terminal (device) and a ConnectReq connection request message that is a link level connection request including device class information. The client terminal and the BAP 123 enter the “Connected” state through the authentication phase and the upper connection phase. Next, the client terminal transmits a host connection request to the host terminal 100. The BAP 123 notifies the host device 100 of the acquired device class based on the Bluetooth address of the client terminal via the BAP 123.
[0066]
The host terminal 100 can recognize from the device class included in the host connection request that the client terminal has made a connection request as a device capable of remote control operation. The host terminal 100 transmits a connection response to the client terminal via the MAP 120 and the BAP 123. When the client terminal receives a connection response from the host terminal 100, the state between the client terminal and the host terminal becomes “Opened”, and various command data can be exchanged.

FIG. 14 is a flowchart showing processing of the host terminal 100. The processing shown in this flowchart is executed by the CPU control unit 101 of the host terminal 100 based on a program.
[0074]
In FIG. 14, when the host terminal 100 is connected to the host terminal 100 (YES in step S1101), the host terminal 100 receives data from the client terminal (YES in step S1102), and receives from the client terminal. If the data is device class information indicating a device class (YES in step S1103), it is determined whether the device class of the client terminal is a PDA or a mobile phone (step S1104).
[0075]
When it is determined that the device class is a PDA or a mobile phone, the host terminal 100 sets the remote control service for the client terminal (even if the client terminal has a small storage capability or display capability such as a PDA or a mobile phone, the client terminal 100 By setting the terminal in the remote control operation mode and compressing and transmitting data from the host terminal 100, a setting for enabling the same service as that of a PC having a large storage capacity and display capacity is performed (step S1105).

FIG. 15 is a sequence diagram showing processing of the entire wireless communication conference system.
[0077]
In FIG. 15, first, the client terminal transmits a ConnectReq connection request message that is a connection request to the BAP 123. The client terminal completes the connection at the link level through the authentication phase, and then goes through the connection phase of the upper layer. When the “Connected” state is reached, the client terminal uses the connected communication path and transmits a host connection request to the host terminal 100 via the BAP 123 and the MAP 120. When the host terminal 100 accepts the host connection request, the host terminal 100 transmits a connection response to the client terminal via the MAP 120 and the BAP 123. At this point, the connection state between the client terminal and the host terminal is “Opened”.
[0078]
Subsequently, the client terminal transmits a device class that is an attribute of the client terminal to the host terminal 100 via the BAP 123 and the MAP 120. When the host terminal 100 receives a device class notification command from the client terminal, the host terminal 100 identifies that the connected client terminal is a device capable of remote control operation. Thereafter, the host terminal 100 transmits a remote control operation confirmation response to the client terminal via the MAP 120 and the BAP 123.
[0079]
As described above, according to the present embodiment, similarly to the first embodiment, even when the client terminal does not include the same application as that of the host terminal 100, the host terminal 100 can be operated by remote control of the client terminal. The application can be operated, and power saving can be realized.
[0080]
In addition, after the Bluetooth communication path is opened, the host terminal 100 can identify whether or not the client terminal is a device capable of remote control operation. In this case, until the communication channel is opened, it is effective when connecting via IP (Internet Protocol) such as a PAN (Personal Area Network) profile, and the remote control operates with the same processing as communication using a wireless LAN or other IP Since a possible device can be recognized, there is a specific effect that the remote control operation of the client terminal can be accepted without making a special distinction between Bluetooth and wireless LAN.
