Description

  The present invention relates to a communication system, and more particularly to a communication system that controls a communication device that performs a two-way communication service such as a videophone or an instant message via an electronic device connected to a network.

  In recent years, with the spread of networks, a plurality of electronic devices are being connected via home networks even at home. There are various types of home networks, such as those using power lines, those using a wired LAN (Local Area Network), and those using a wireless LAN. This is a function for checking and controlling the state of the device from a room different from the room where the device is placed. Such remote control of devices using a home network is expected to become increasingly popular in the future.

  Patent Document 1 discloses a technique for notifying another electronic device of a warning state generated in a certain electronic device connected to a home network.

  On the other hand, as a service using a network, in recent years, interactive communication services such as a videophone and an instant message have been expanded. Many of these two-way communication services use “presence” that is not available in conventional communication devices. Presence is information indicating the status of a device or user. A user who wants to communicate can determine in advance whether the other party can communicate by checking the presence of the other party prior to the communication.

Patent Document 2 discloses a technology for determining the state of a user based on the opening / closing status of a foldable cellular phone, the operation status of an antenna or a button, and notifying the other party of the cellular phone.

  Next, an operation flow when the communication device 100 and the electronic device 200 according to the present embodiment are connected will be described with reference to FIGS. 4 to 7.

  FIG. 4 is a data flow diagram showing exchanges at the time of connection between the communication device 100 and the electronic device 200 in the present embodiment. It is assumed that the communication device 100 and the electronic device 200 are connected to the network 300 in advance. The communication device 100 according to the present embodiment operates as a server, and the electronic device 200 according to the present embodiment operates as a client.

  First, when either of the following two requirements is satisfied, a search request for server device (information requesting device information) is transmitted from the electronic device 200 to the network 300 (step S401). The message transmission unit 208 of the electronic device 200 controls the communication unit 202 to transmit the search request. The first requirement for transmitting the search request is that the electronic device 200 is newly connected to the network 300. The second requirement is that any power source of the electronic device 200 connected to the network 300 is turned “on”. The search request is transmitted to all devices connected to the network 300.

  The communication device 100 that has received the search request transmits its own device information to the electronic device 200 (step S402). Accordingly, when the communication unit 102 receives information from the electronic device 200 that requests device information that is information including the identifier of the electronic device 200, the message transmission unit 110 of the communication device 100 requests the device information. The communication unit 102 is controlled to transmit the device information to the electronic device 200 that has transmitted the information to that effect.

  FIG. 5 is an example of device information held by the communication device 100 and the electronic device 200 according to the present embodiment.

  The device information 500 includes information indicating each item of the device type 501, device providing service 502, and device occurrence event 503, and device type data 504, device providing service data representing the contents thereof by data. 505, and device occurrence event data 506.

  The message analysis unit 206 of the electronic device 200 that has received the device information 500 analyzes the device information 500 to determine what kind of server is connected to the network 300, or a server connected to the network 300. It is possible to know what functions are supported and what the destination addresses on the network 300 are.

  The electronic device 200 that has received the device information 500 from the communication device 100 issues a registration request to the communication device 100 (step S403). The “registration request” is to transmit information (registration information) including information on the type of the electronic device 200 together with information on the identifier of the electronic device 200. When the communication unit 202 receives the device information 500, the message transmission unit 208 of the electronic device 200 controls the communication unit 202 to transmit registration information to the communication device 100 using the identifier of the communication device 100. . As a result, the electronic device 200 is registered in the communication device 100. When the electronic device 200 is registered in the communication device 100, an event occurring in the communication device 100 can be received.

  Next, the exchange operation between the communication device 100 and the electronic device 200 at the time of connection will be described for each device with reference to the drawings.

FIG. 6 is a flowchart when the communication device 100 is connected in the present embodiment.
First, in step S <b> 601, the communication unit 102 waits for a search request from another electronic device 200. If there is a search request, the process proceeds to step S602, and the communication unit 102 transmits device information 500 to the electronic device 200 that has transmitted the search request under the control of the message transmission unit 208. In step S603, the communication unit 102 waits for a registration request from the electronic device 200. If there is a registration request (when the communication unit 102 receives information including the identifier information of the electronic device 200), the process proceeds to step S604.

  In step S604, the second storage unit 111 stores information included in the registration information. In the case of the present embodiment, the information that is actually stored is information on the identifier of electronic device 200 and information on the type of electronic device 200 (for example, “TV”). In addition, an event is set to be transmitted to the electronic device 200 in which the destination is stored. That is, the control unit 101 stores information indicating that a message should be transmitted in the second storage unit 111. As a result, an event (also referred to as “event message”) can be transmitted to the registered electronic device 200 as a number corresponding to the content of the message. This is because in the present embodiment, electronic device 200 can receive an event. Then, the process proceeds to step S605, and the changing unit 114 updates the presence. Here, updating the presence means changing the information of the electronic device 200 stored in the second storage unit 111 such as “at home” to “at home (using TV)”. At the same time as the presence is updated, the changing unit 114 causes the second storage unit 111 to store the address of the destination and the type of the electronic device 200 represented by the destination. There are a method of representing the type of electronic device 200 as a method of representing as an ID and a method of representing as a character string.

  When the type of the electronic device 200 is expressed as an ID, for example, a device ID defined by the DLNA guidelines is used, such as a television if the ID value is “1” and an audio device if the ID is “2”. When representing the type of electronic device 200 as an ID, the changing unit 114 can update the presence from “at home” to “at home (using XXX)” using this ID. The “XXX” portion of “at home (using XXX)” represents the name of the device corresponding to the ID.

  When the type of the electronic device 200 is represented as a character string, the character string itself stored in the second storage unit 111 is used instead of replacing the name of the device corresponding to the ID. That is, the part “XXX” is replaced with the character string stored in the second storage unit 111. In any method, the changing unit 114 may change the phrase “in use” according to the device. For example, if the ID is “1” or the character string is “TV”, the phrase “busy” may be used instead of the phrase “in use”. If the ID is “3” or the character string is “DVD”, the phrase “watching” may be used instead of the phrase “in use”. If there is no registration request in step S603, the processing of the communication device 100 is terminated as it is.

FIG. 7 is a flowchart at the time of connection of electronic device 200 in the present embodiment.
First, in step S <b> 701, the communication unit 202 transmits a search request under the control of the message transmission unit 208. Next, if the determination unit 210 determines that the device information 500 can be acquired in step S702 (YES in step S702), the process proceeds to step S703, and the communication unit 202 waits until the device information 500 is acquired.

  If the device information 500 can be acquired, the message analysis unit 206 analyzes the device information 500. In step S <b> 704, the determination unit 210 determines whether the analyzed device information 500 is for the communication device 100.

  If analyzed device information 500 is not for communication device 100 (NO in step S704), control of electronic device 200 proceeds to step S708. In step S708, each unit of the electronic device 200 performs processing corresponding to the content of the analyzed device information 500. After the corresponding processing ends, the control of the electronic device 200 returns to step S702 via step S701.

  If analyzed device information 500 is for communication device 100 (YES in step S704), control of electronic device 200 proceeds to step S705. In step S <b> 705, the determination unit 210 determines whether to receive an event from the communication device 100. This determination may be based on criteria set in advance by the user, or may be in accordance with the user's determination each time a determination is made. If an event is received (YES in step S705), control of electronic device 200 moves to step S706. In step S706, the storage unit 209 stores the destination of the communication device 100 under the control of the control unit 201. After the destination is stored, the control of the electronic device 200 moves to step S707. In step S <b> 707, the communication unit 202 transmits a registration request to the communication device 100 under the control of the message transmission unit 208. Thereby, it is possible to receive an event notification from the communication device 100.

  Next, the control of the electronic device 200 goes back to step S705 through steps S702 to S704. If no event is received in step S705 (NO in step S705), control of electronic device 200 returns to step S702. In step S702, if communication unit 202 cannot acquire more device information 500 (NO in step S702), control of electronic device 200 is terminated.

  In this embodiment, the communication device 100 returns the device information 500 immediately in response to the search request from the electronic device 200. However, the communication device 100 responds to the search request by using the device information 500. After returning the stored URL, the electronic device 200 may be divided into a plurality of sequences so as to obtain the device information 500 stored in the URL. In addition, when there is a registration request from the electronic device 200, the communication device 100 is configured so that the event can be transmitted to the electronic device 200. However, this also includes a registration only sequence and an event request only sequence. , May be divided into a plurality of sequences.

  When the connection is made as described above, the communication device 100 and the electronic device 200 can know each other's device information and destination. If the device information and the destination of the other party can be known, it becomes possible to identify and communicate with each other by using the destination.

  FIG. 8 and FIG. 9 are schematic diagrams when a communication device 800 at another location is connected to each device in the communication system 1 including the communication device 100 and the electronic device 200 of the present embodiment. . The communication device 800 performs bidirectional communication with the electronic device 200 in the communication system 1 of the present embodiment. In this example, the communication device 800 displays the presence of many communication partners connected to the communication device 800. In order to display the presence, the message transmitting unit 110 of the communication device 100 uses the presence (such as “in use”) stored in the third storage unit 113 as information corresponding to the type of the electronic device 200 to the communication device 800. In this embodiment, “at home” or “absence” is also a kind of presence) and information indicating the type of electronic device 200 (this information is stored in the second storage unit 111). The communication unit 102 is controlled to transmit to the communication device 800. In the case of the present embodiment, normally, “at home” or “absent” is displayed on the display of the communication device 800 as shown in FIG. When “information corresponding to the type of electronic device 200” is transmitted, information indicating the usage status of electronic device 200 by the user (“in use” in FIG. 8) and information indicating the type of electronic device 200 ( In the case of FIG. 8, “TV”) can also be displayed.

  In the communication system 1 including the communication device 100 and the electronic device 200 according to the present embodiment, the communication device 800 can acquire a part of the operation of the electronic device 200 connected to the network 300. As shown, for example, if the TV is being operated, more detailed contents such as “at home (using TV)” can be presented to the communication partner.

  Next, the flow from the communication device 100 and the electronic device 200 according to the present embodiment to the presentation that the incoming call has been received will be described with reference to FIGS.

  FIG. 10 is a data flow diagram showing exchanges until presentation that the communication device 100 and the electronic device 200 have received an incoming call in the present embodiment.

  The detection unit 112 of the communication device 100 determines whether an incoming call has occurred from the communication device that is a communication device independent of the communication system 1 according to the present embodiment (the communication unit 102 displays information indicating a request for an incoming call). Or not). When an incoming call occurs in the communication device 100, the message transmission unit 110 controls the communication unit 102 to notify the registered electronic device 200 that an “incoming event” has occurred (step S901). The electronic device 200 that has received the “incoming event” requests the communication device 100 to obtain an incoming message in order to know the content of the incoming call (step S902). The control unit 101 of the communication device 100 receives the information indicating the incoming call request, and generates a message information so as to create message information including the information indicating the incoming message when the incoming message request is received. The unit 109 is controlled. The message transmission unit 110 transmits the identifier information and message information of the electronic device 200 as an “incoming message” to a device corresponding to information indicating that the identifier desires transmission of the incoming message among the electronic devices 200. Thus, the communication unit 102 is controlled.

  FIG. 11 is an example of an incoming message in the present embodiment. The incoming message 1000 is information indicating each item of the display message 1001, incoming content URL 1002, applicable service and guide message 1003, and display message data 1004, incoming content URL data 1005, which is information indicating the contents thereof, applicable. It consists of service and guide message data 1006 data. The display message data 1004 is data representing a display message for presenting an incoming call to the electronic device 200. The incoming content URL (Uniform Resource Locator) data 1005 is, for example, a substitute for data such as an incoming melody. The incoming content URL data 1005 is data representing the address of content (in this case, incoming melody) for notifying the user of incoming by URL (in the case of the present embodiment, this content is stored in the communication device 100). ) The applicable service and guide message data 1006 includes a service that can be used by the communication device 100 when an incoming call is presented by the electronic device 200, and a guide message that should be displayed when the user selects the service. It is data. As a result, the control unit 101 controls the message generation unit 109 so as to create information including information representing an incoming message together with information to be output together with the incoming message as message information. “Information to be output together with the incoming message” is information indicating the correspondence that the user can select for the incoming call request. In the case of the present embodiment, the guide message to be displayed when the user makes a selection corresponds to “information indicating the correspondence that the user can select with respect to an incoming call request”.

  When the communication unit 202 of the electronic device 200 receives the incoming message 1000 from the communication device 100 (step S903), the message analysis unit 206 of the electronic device 200 analyzes the message. The output unit 204 of the electronic device 200 outputs an analyzed message (any of the information received from the communication device 100 by the communication unit 202) under the control of the control unit 201, so that the user receives an incoming call. Can be notified. In addition, the electronic device 200 can not only present the incoming call to the user, but can also acquire incoming notification content from the communication device 100, reproduce the content, and present the incoming call to the user.

  FIG. 12 is an example of incoming call presentation in the electronic device 200 of the present invention. Information is displayed on the screen in accordance with the contents of the incoming message shown in FIG. By confirming this, the user can know that the communication device 100 has received an incoming call.

  As described above, when an incoming event is transmitted from the communication device 100 to the electronic device 200 at the time of an incoming call, the electronic device 200 acquires the incoming message 1000 from the communication device 100, analyzes it, and presents it to the user. The person can know the incoming call of the communication device 100 by using the electronic device 200 located away from the communication device 100. That is, according to the communication system 1 according to the present embodiment, the incoming call can be presented not only by the communication device 100 but also by the electronic device 200 connected to the network in use by the user. As a result, an opportunity for the user to notice the incoming call increases and a quick response to the communication device 100 becomes possible. In addition, the communication partner can be notified as a presence that the user has accepted the incoming call, and can recognize that the user has confirmed the incoming call until communication is actually established. .

  Further, by determining the state of the user from the usage status of the electronic device 200 connected to the network and using it as the presence of the communication device 100, more accurate presence can be transmitted to the communication partner.

  Further, the communication device 100 receives an apparatus for reading a program for realizing the communication device 100 according to the present embodiment from a flash memory, and a program for realizing the communication device 100 according to the present embodiment via the Internet. An apparatus for further may be included. The same applies to the electronic device 200.

<Second Embodiment>
The communication system according to the second embodiment of the present invention will be described below.

  In the first embodiment, when the communication device 100 receives an incoming call, the portion that presents the incoming call to another electronic device 200 connected to the network has been described. In addition, in the second embodiment, a method of controlling the communication device 100 with respect to an operation performed by the user on the electronic device 200 after the incoming call presentation will be described. The hardware configuration is the same as that of the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  First, the flow of processing after presenting an incoming call between the communication device 100 and the electronic device 200 according to the present embodiment will be described with reference to FIGS.

  FIG. 13 is a data flow diagram showing the exchange of the entire incoming call between the communication device 100 and the electronic device 200 according to the present embodiment. In the flowchart shown in FIG. 13, the processing shown in FIG. 10 is given the same step number. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  The difference from the data flow diagram of FIG. 10 is that after presenting incoming call information, an input operation from the user is waited, and a device control message is transmitted to the communication device 100 according to the result (step S1204). is there.

  For example, when the incoming message 1000 shown in FIG. 11 is acquired, the message to be displayed is “incoming from Mr. XX”. The services applicable at that time are “incoming call confirmation”, “reception of incoming call”, and “ignore incoming call”. Information indicating the correspondence that can be selected by the user for the incoming call request output by the output unit 204 is “confirmation”, “rejection”, and “ignore”. The display of the electronic device 200 has the same contents as in FIG. When the output unit 204 outputs information indicating the correspondence that the user can select for the incoming call request, the control unit 201 displays information indicating one of the correspondences that the user can select for the incoming call request ("confirmation"). , “Reject” and “Ignore”).

  Here, the operation of the electronic device 200 to which the applicable service is assigned or whether the applicable service is not assigned to the electronic device 200 is a matter arbitrarily determined by the designer of the electronic device 200. For example, if there are few operation keys of the electronic device 200, it is not necessary to assign all services to the operation keys. Only the first one of “confirmation”, “rejection”, and “ignore” may be assigned. Further, three buttons 1301 of “A”, “B”, and “C” on the remote controller 1300 as shown in FIG. 14 may be assigned to each applicable service.

  When the operation unit 203 receives information indicating correspondence (in the case of the present embodiment, any one of “confirmation”, “rejection”, and “ignore”), the message transmission unit 208 receives a device control message (the operation unit 203 The communication unit 202 is controlled to transmit the information indicating the accepted correspondence).

  The communication device 100 that has received the device control message performs processing corresponding to the content. For example, if the device control message instructs execution of the “incoming call confirmation” service, the communication device 100 executes the “incoming call confirmation” service. Here, the “incoming call confirmation” service is a service that notifies the communication partner that the user has confirmed the incoming call. For example, a voice message “Please wait for a while” may be transmitted to the other party, but here, this is realized by updating the presence of the communication device 100. That is, when the presence is updated, the presence notified to the communication device 800 of the communication partner is also updated, so that the communication partner can know that the user has responded to the incoming call. In the case of the present embodiment, communication device 100 has a mechanism for immediately transmitting a change in presence to communication device 800 (message generation unit 109 creates a message indicating the content of the presence after the change, and message transmission unit 110 This is because it has a mechanism for controlling the communication unit 102 so as to transmit information indicating the contents of presence after the change. In order to execute the “incoming call confirmation” service, the operation unit 203 indicates that “acknowledgement of incoming call” should be performed as information indicating correspondence that can be selected by the user (request for incoming call from the communication device 800). Message transmission unit 208 controls communication unit 202 to transmit a device control message (information indicating the response accepted by operation unit 203). .

  FIG. 15 is a display example of the communication device 800 of the communication partner when an incoming call is received. The output unit 801 displays a calling screen and also displays “Mr. A: at home (using TV)” as the presence 802. At this time, the electronic device 200 on the communication system 1 including the communication device 100 and the electronic device 200 of the present invention displays as shown in FIG. FIG. 16 shows a case where the user selects “Confirm”. FIG. 17 shows a case where the user selects “reject”. When “ignore” is selected, there is no particular change in display on the communication device 800 on the communication partner side.

  In this embodiment, when “Confirm” is selected, the presence 802 changes from “at home (using TV)” to “at home (moving)”. This is because the changing unit 114 of the communication device 100 updates the presence so that information indicating the action that the user will take is added as an “incoming call confirmation” service. As a result, the communication partner knows that the user who was using the TV notices the incoming call and is moving to use the communication device 100. In addition, when updating presence with the “incoming call confirmation” service, arbitrary information input in advance by the user may be used. When using arbitrary information previously input by the user, “arbitrary information previously input by the user” is included as data in the registration information in step S403. Thus, for example, if the presence is updated to something like “Now moving toward the videophone”, the communication partner can acquire a more accurate presence.

  When “Reject” is selected, the disconnection screen 803 is displayed instead of the presence 802. As a result, the communication partner knows that the user who was using the TV noticed the incoming call and performed the disconnection process. In order to execute the “incoming call rejection” service, the operation unit 203 should make “incoming call rejection” as information indicating correspondence that can be selected by the user (request for incoming call from the communication device 800). Message transmission unit 208 controls communication unit 202 to transmit a device control message (information indicating the response accepted by operation unit 203). . When the communication unit 102 receives information indicating that the incoming call request from the communication device 800 is rejected as a device control message, the message transmission unit 110 of the communication device 100 transmits information indicating that the incoming call request is rejected. As described above, the communication unit 102 is controlled.

  In addition to “confirmation”, “rejection”, and “ignore”, the applicable service related to the incoming call may include “hold” and “forward”. For example, in the case of the “transfer” service, the communication device 100 accepts an incoming call, establishes a connection with the communication device 800 as a communication partner, and transmits video data and audio data sent from the communication device 100 to the electronic device 200. If the video data and audio data sent from the electronic device 200 are sent to the communication device 800, the electronic device 200 can be handled as if it were the communication device 100. In this case, when the communication unit 102 receives information indicating that the communication unit 102 wishes to transfer information from the communication device 800 as a device control message, the message transmission unit 110 of the communication device 100 receives the information from the communication device 800 to the electronic device 200. The communication unit 102 is controlled to transmit information. In the electronic device 200, the operation unit 203 responds to the fact that “call transfer” is to be performed (information transfer from the communication device 800 is desired) as information indicating correspondence that the user can select. When the information to be received is received, a device control message (information indicating the correspondence received by the operation unit 203) instructing the execution of the “call transfer” service (to request transfer of information from the communication device 800) is transmitted. Next, the communication unit 202 is controlled. When a device control message instructing execution of the “call transfer” service is transmitted, the output unit 204 outputs any of the information (video data and audio data) received by the communication unit 202 from the communication device 100. Become. If it is “pending”, a message such as “please wait” is displayed on the communication device 800 by the same processing as the “reception confirmation” service.

  Next, operations of the communication device 100 and the electronic device 200 for the entire incoming call will be described with reference to the drawings.

  18 and 19 are flowcharts at the time of incoming call of communication device 100 in the present embodiment.

  First, in step S1501, the detection unit 112 detects whether there is an incoming call. If there is no incoming call (NO in step S1501), step S1501 is repeated. If detection unit 112 detects an incoming call (YES in step S1501), the process proceeds to S1502, and control unit 101 prepares for the incoming call. Here, the output unit 106 presents an incoming call so that the incoming operation can be performed by operating the input unit 105.

  Next, the process moves to step S1503, and the control unit 101 determines whether or not the destination of the electronic device 200 to which the message is to be transmitted is registered in the second storage unit 111. If the destination is not registered or the registered destination does not permit event reception (NO in step S1503), the process proceeds to step S1508.

  If the registered destination permits event reception (YES in step S1503), the process proceeds to step S1504, and communication unit 102 and message transmission unit 110 transmit an incoming event to the destination. The electronic device 200 that has received the incoming event transmits information requesting acquisition of incoming information as a device control message. In step S1505, the communication unit 102 and the message receiving unit 107 wait for the request.

  When the communication unit 102 receives a device control message from the electronic device 200, the process proceeds to step S1506, and the control unit 201 controls the message generation unit 109 so as to create message information corresponding to the device control message. When the message generation unit 109 is controlled, the message transmission unit 110 controls the communication unit 102 to transmit message information corresponding to the device control message to the communication device 800. Then, the process proceeds to step S1507, and after the communication unit 102 and the message transmission unit 110 transmit an incoming message to the electronic device 200, the process proceeds to step S1508.

  In step S1508, the detection unit 112 determines whether the incoming call is disconnected. If disconnected (YES in step S1508), the process proceeds to step S1516. If the incoming call continues (NO in step S1508), the process proceeds to step S1509.

  In step S1509, the communication unit 102 and the input unit 105 wait for control input. The communication unit 102 and the input unit 105 wait until one of operation of the input unit 105 by the user and reception of a message from the electronic device 200 is performed as a control input. In step S1510, the control unit 101 determines whether or not the user has operated the input unit 105. If there is an operation by the user (YES in step S1510), the process proceeds to step S1511. If not (NO in step S1510), the process proceeds to S1513.

  In step S1511, the control unit 101 checks whether the user operation is an incoming call operation. If the operation by the user is a refusal operation (NO in step S1511), the process directly proceeds to S1516. If the operation by the user is an incoming operation (YES in step S1511), the process proceeds to step S1512. In step S1512, control unit 101 performs normal incoming call processing. Thereby, the communication with the communication partner is started. At this time, when the communication unit 102 receives a device control message from the electronic device 200, the message transmission unit 110 controls the communication unit 102 so as to respond to an incoming call request from the communication device 800. The message transmission unit 110 controls the communication unit 102 so that the information received by the communication unit 102 from the communication device 800 is transmitted to the electronic device 200. When the communication ends, the process moves to step S1516.

  In step S1513, control unit 101 checks whether or not the operation by the user is ignoring incoming calls. If the operation by the user is an incoming call confirmation (NO in step S1513), the process directly proceeds to S1514. If the operation by the user is ignored (YES in step S1513), the process proceeds to step S1508.

  In step S1514, control unit 101 checks whether the operation by the user is an incoming call confirmation. If the operation by the user is call rejection (NO in step S1514), the process directly proceeds to S1516. If the operation by the user is an incoming call confirmation (YES in step S1514), the process proceeds to step S1515. In step S1515, the third storage unit 113 updates the presence under the control of the control unit 101. When the presence is updated, the process proceeds to S1508.

  In step S1516, control unit 101 performs a cutting process. After the cutting process, the process proceeds to step S1517. In step S1517, the control unit 101 determines whether the destination of the electronic device 200 to which the message is to be transmitted is registered in the second storage unit 111 and event reception is permitted. If the destination is registered and event reception is permitted (YES in step S1517), the process proceeds to S1518, and communication unit 102 and message transmission unit 110 transmit a disconnection event to the destination and end. If the destination does not permit event reception (NO in step S1517), the process ends as it is.

FIG. 20 is a flowchart at the time of incoming call of the electronic device 200 in the present invention.
First, in step S1601, the communication unit 202 and the message reception unit 205 wait for event reception. If an event is received, the process proceeds to step S1602. In step S1602, the message analysis unit 206 determines whether the event is a disconnection notification. If the event is an incoming call notification from communication device 100 (NO in step S1602), the process branches to step S1603. If the event is a disconnection notification from communication device 100 (YES in step S1602), the process branches to step S1612.

  In step S1603, the message analysis unit 206 determines whether the event is an incoming call notification. If the event is an incoming notification from communication device 100 (YES in step S1603), the process branches to step S1604. If the event is another event (NO in step S1603), the process branches to step S1613.

  In step S <b> 1604, the message transmission unit 208 and the communication unit 202 transmit the incoming message acquisition request generated by the message generation unit 207 to the communication device 100 under the control of the control unit 201. Next, the process moves to step S1605, and the message receiving unit 205 and the communication unit 202 receive an incoming message transmitted from the communication device 100. When the incoming message is received, the process proceeds to step S1606, and the message analysis unit 206 analyzes the incoming message. Next, the processing moves to step S1607, and the output unit 204 presents the result analyzed by the message analysis unit 206 as an output under the control of the control unit 201.

  Next, the process moves to step S1608, and the control unit 201 determines whether or not the user can perform some control according to the presented output. The control unit 201 determines that control is impossible if there is no applicable service in the incoming message. Even if there is an applicable service, the control unit 201 determines that control is impossible unless the electronic device 200 can allocate it. If it is determined that control is impossible (NO in step S1608), the process proceeds to step S1601. If control is possible (YES in step S1608), the process proceeds to step S1609.

  In step S609, the operation unit 203 waits for input of the assigned operation. If there is an input of the assigned operation, the process proceeds to step S1610, and the message generation unit 207 generates a device control message. Then, the process proceeds to step S <b> 1611, and the communication unit 202 and the message transmission unit 208 transmit a device control message to the communication device 100. At this time, when the operation unit 203 receives from the user information indicating correspondence corresponding to communication with the communication device 800 as information indicating correspondence that can be selected by the user, the message transmission unit 208 displays the device control message (operation The communication unit 202 is controlled so as to transmit information representing the correspondence received by the unit 203. Thereafter, the process proceeds to step S1601.

  In step S1612, when the output unit 204 deletes the content presented to the user in step S1607, the process ends. In step S1613, each unit of the electronic device 200 performs processing corresponding to the content of the event, and the process proceeds to step S1601.

  As described above, as shown in FIG. 1, when an incoming event is transmitted from the communication device 100 to the electronic device 200 at the time of an incoming call, the electronic device 200 acquires and analyzes the incoming message from the communication device 100, and the user By presenting the information, the user can know the incoming call of the communication device 100. At that time, the user's operation is prompted by presenting the user with any possible operation. If there is an operation, the communication device 100 can be controlled in accordance with the operation.

  If the presence is changed through the processing of S1510, S1513, and S1514 as control of the communication device 100, as shown in FIG. 21, the presence of the user confirming the incoming call to the communication partner is confirmed. It becomes possible to notify using.

<Third Embodiment>
The communication system according to the third embodiment of the present invention will be described below.

  In the first embodiment and the second embodiment, when the communication device 100 and the electronic device 200 are connected, the presence of the communication device 100 is converted into detailed information including the type of the electronic device 200. Explained about updating. Further, in the second embodiment, the presence of the communication device 100 is obtained by operating the electronic device 200 when an incoming call is being presented, and the detailed information including the user's action, or arbitrarily We explained about updating to information.

  Here, how the presence of the communication device 100 is controlled after the user actually leaves the electronic device 200 and communicates with the communication device 100 will be described.

  The hardware configuration of the communication system 1 according to the present embodiment is the same as that of the first embodiment. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  FIG. 22 is a flowchart of communication device 100 at the time of presence update of communication system 1 including communication device 100 and electronic device 200 according to the present embodiment.

  First, in step S <b> 1701, the communication unit 102 and the message receiving unit 107 wait until an event request is received from the electronic device 200. If there is an event request, the process moves to step S1702, and the message analysis unit 108 determines whether the received event request is an event notification request.

  If the received event request is an event notification request (information indicating whether or not an incoming message is desired to be transmitted) (YES in step S1702), the process proceeds to step S1703, and second storage unit 111 stores The destination is updated under the control of the control unit 101. Information indicating that event reception is permitted is attached to the destination. Then, the process proceeds to step S1704, and the third storage unit 113 updates the presence stored therein to a detailed presence including the device type under the control of the control unit 101.

  If the received event request is an event cancel request (NO in step S1702), the process proceeds to step S1705, and the second storage unit 111 updates the destination under the control of the control unit 101. Information indicating that event reception is permitted is removed from the destination. Then, the process proceeds to step S1706, and the third storage unit 113 updates the presence stored by itself to the presence from which the device type is removed under the control of the control unit 101. By the processing in steps S1703 and S1705, the control unit 101 of the communication device 100 transmits the incoming message when the communication unit 102 receives information indicating whether or not the electronic device 200 desires transmission of the incoming message. In accordance with the content of the information indicating whether or not it is desired, the content of the information indicating whether or not to transmit the incoming message stored in the second storage unit 111 is updated.

  FIG. 23 is a flowchart of the electronic device 200 at the time of updating the presence of the communication system 1 including the communication device 100 and the electronic device 200 according to the present embodiment.

  First, in step S1801, the operation unit 203 waits until a user operation is performed. If there is a user operation, the process proceeds to step S1802, and the control unit 201 determines whether or not it is necessary to retransmit the event notification request. For example, when the electronic device 200 has been set not to accept an incoming call from the communication device 100, or when an event notification request has been issued in the past, an event has not yet been received. Judged not. In other cases, it is determined that retransmission is necessary. If it is determined that retransmission is necessary (YES in step S1802), the process proceeds to step S1803, and communication unit 202 and message transmission unit 208 transmit an event notification request. Thereby, when the operation unit 203 receives information indicating whether or not the transmission of the incoming message 1000 is desired, the message transmission unit 208 transmits information indicating whether or not the transmission of the incoming message is desired. The communication unit 202 is controlled. When the event notification request is transmitted, the process proceeds to step S1804. If it is determined that retransmission is not necessary (NO in step S1802), the process directly proceeds to step S1804. In step S1804, the control unit 201 performs some processing corresponding to the input operation.
