Description

The present invention, online controller state controls the connection by the data connection between the terminal devices connected with the network (line), the system ,, method, the service server, you and the proxy server, and a program.

  As wireless terminals (cell phones, PDAs, etc.) become more sophisticated and the capacity of wireless networks increases, applications that perform real-time communication such as messenger services are also used on the go. These applications establish a data connection between a terminal server and a service server that manages application users, messages, and connection (online) states. As a result, an active state is maintained between each data connection (data session) with a plurality of terminals, and messages such as messages can be immediately transmitted and received between the terminals. Such an application is defined as a connection-type application, and a state in which an active data session is held (a data connection is established) is defined as an online state.

  On the other hand, since the wireless terminal is small and light, the battery duration is short and the connection cost of the wireless network is high. Therefore, it is difficult to always operate the connection-type application as described above on the wireless terminal and maintain the online state. For this reason, there is a demand for realizing immediate communication even if the connection-type application is not always operating on the wireless terminal.

  In response to such a request, even if the connection between the connection-type application and the service server is not maintained, the service server can receive the message even if the application as described above is not operating. There is a technology that virtually considers an online state (see Non-Patent Documents 1 and 2).

  In this technique, when the wireless terminal A is in a virtual online state, the service server accepts a message from another connection type application (wireless terminal B). The service server that accepts the message in this way notifies the wireless terminal A that the message has been received by a connectionless application that sends data without holding an active data session such as an e-mail or a short message.

  If the wireless terminal A is connected to the network, the notification by the connectionless application described above is received by the wireless terminal A. When a connection-type application is started on the received wireless terminal side, triggered by the notification received in this way, a connection with the service server is established, and messages can be transmitted and received between the wireless terminals. Become. According to this technology, even if no connection-type application is operating on the wireless terminal, a data connection is virtually established (online).

  In addition, there is a technique for notifying the other party by other communication means when communication using a data session is not possible (see Non-Patent Document 3, Patent Documents 1, 2, and 3). In this technology, based on conditions such as network communication quality and wireless terminal type, the presence engine installed on the wireless terminal determines the user status, application settings, etc., and shares these as presence information among wireless terminals. To do.

  When a wireless terminal (self terminal) inquires about the presence information to another wireless terminal (other terminal), if there is no response due to power interruption or out of communication area, a backup that maintains the presence function instead of the other terminal Inquire the server and receive the current status of other users who have not responded and other contact methods. Thereby, the user of the own terminal can notify the user of the other terminal by another contact method.

  In addition, in a state where other terminals cannot receive data, the custody retransmission server keeps the data in place of the other terminal, and after the wireless terminal returns, notifies the application that the wireless terminal keeps the data, and keeps the data Can be downloaded to other devices. With these functions, even if the application is not always running on the wireless terminal, such as when the wireless terminal is outside the communication area, the presence information notified to other wireless terminals is used to notify among users of the wireless terminals. You can also receive custody messages after starting the application.

  However, in the technology for virtually online, the wireless terminal is online to a connection-type application in another wireless terminal regardless of the connection state between the terminal and the network, such as whether the wireless terminal exists within the wireless network area. To notify. For this reason, for example, when the wireless terminal is not in the wireless network area and the message cannot be transmitted / received by the connectionless application, the real-time communication by the connection application is established even though the online state is notified. There is a problem that cannot be made.

  Also, in the technology using presence information, when trying to communicate with an offline wireless terminal, first confirm that the wireless terminal is offline, then acquire the contact method from the backup server, Will be notified that communication is desired. For this reason, this technique has a problem that a certain procedure is required on the requesting wireless terminal side. In addition, there is a problem in the requested wireless terminal that a certain time is required until a connection-type application for realizing real-time communication is activated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Embodiment 1]
First, the first embodiment of the present invention will be described. FIG. 1 is a configuration diagram showing the configuration of the online state control device according to Embodiment 1 of the present invention. This online state control device can be connected to a plurality of terminal devices including the terminal device A 131 and the terminal device B 132 via the network 120. For example, the network 120 is a wireless network such as a wireless WAN (3GPP, 3GPP2), a wireless MAN (IEEE802.16 / 20), a wireless LAN (IEEE802.x), a cellular phone network, or the like. The terminal device is a PDA (Personal Data Assistance) that can be connected to the network 120 as described above, for example, and a mobile phone.

  The online state control device that can be connected to a plurality of terminal devices as described above includes a network connection determination unit 101 that first determines that the connection between the terminal device A 131 and the network 120 is established. The net frame connection determination unit 101 performs the above-described determination based on connection confirmation information transmitted from any terminal device such as the terminal device A131 or the terminal device B132. For example, the network connection determination unit 101 determines connection establishment with the network 120 for the terminal device A131 and the terminal device B132 registered in advance. In addition, the network connection determination unit 101 determines connection establishment with the network 120 with respect to the terminal device A 131 and the terminal device B 132 that have a record in which a data connection has been established in the past.

  For example, the network connection determination unit 101 can be determined based on connection confirmation information such as a connection request to the network 120 transmitted from the wireless terminal device and a response from the cellular phone to a connection confirmation signal (beacon) transmitted to the cellular phone. Determines establishment of connection to the network 120. Here, for example, it is assumed that the mobile phone is connected to the mobile phone network (network) even in a state where the mobile phone is in a callable area.

  Further, for example, even if the connection establishment state with the network 120 is determined by acquiring information indicating a state in which the connection request is accepted from an authentication server that performs authentication when the wireless terminal device connects to the network 120. Good. In addition, the connection establishment state with the network 120 may be determined by acquiring information indicating that the mobile phone is present in the callable area from the mobile phone base station.

  Further, the online state control device is configured to establish a data connection between the data connection establishment unit 102 that establishes a data connection with the requesting terminal device based on a request from the terminal device, and each data connection established by the data connection establishment unit 102. And a relay unit 103 that relays. The terminal device with which the data connection establishing unit 102 has established the data connection is brought online.

  For example, when the user activates the connection-type application on the terminal device B 132, a data connection establishment request is transmitted to the network 120, and this establishment request is accepted by the online state control device via the network 120. In response to this establishment request, the data connection establishment unit 102 establishes a data connection with the requesting terminal device B 132 and enters an online state. In this way, in a state where the data connection with each terminal device is established, the relay unit 103 relays between each data connection, so that communication between different terminal devices in real time such as a messenger service is possible. Realized.

  The online state control device determines that the connection with the network 120 is established by the data connection determination unit 104 that determines that the data connection with the terminal device is not established and the network connection determination unit 101. In addition, the terminal device for which it is determined by the data connection determination unit 104 that the data connection has not been established includes a terminal state setting unit 105 that sets that the data connection is virtually established.

  For example, it is assumed that the terminal device A131, which is a mobile phone, exists in an area where communication is possible, but the connection-type application as described above is not activated. In this case, the network connection determination unit 101 determines that the terminal device A 131 is connected to the network 120. On the other hand, the data connection determination unit 104 determines that a data connection with the terminal device A 131 has not been established. Accordingly, the terminal state setting unit 105 sets the terminal device A 131 in the above-described state to have a virtual data connection established (virtual online state).

  If the terminal state setting unit 105 determines that the terminal device A 131 is not connected to the network 120 by the network connection determining unit 101, the terminal device A 131 is in an offline state in which no data connection is established. And set. If the data connection determination unit 104 determines that the data connection with the terminal device A131 is established, the terminal state setting unit 105 determines that the terminal device A131 has an established data connection (online state). ) And set.

  In addition, the online state control device accepts a connection request for the virtual data connection of the terminal device A131 which is set as a virtual data connection established by the terminal state setting unit 105, for example, and sends it to the terminal device A131. A data connection establishment request transmission notification unit 106 that notifies transmission of a data connection establishment request is provided. For example, when receiving a data connection relay request by the terminal device B 132 for the virtual data connection of the terminal device A 131, the data connection establishment request transmission notification unit 106 notifies the terminal device A 131 of the transmission of the data connection establishment request.

  The data connection establishment request transmission notification unit 106 notifies the terminal device A 131 of the transmission of a data connection establishment request by a connectionless application such as e-mail or a short message. If the user of the terminal device A131 starts a connection-type application on the terminal device A131 and the connection-type application is operating by this notification, first, the terminal device A131 sends a data connection establishment request. The Note that the connectionless application of the terminal device A131 may automatically start the connection-type application based on the received notification.

  For example, the data connection establishment request transmission / notification unit 106 may use MIME (Multipurpose Internet Mail Extension) or the like for the notification message and store data necessary for starting the connection-type application. In the terminal device that has received such a notification message, the connectionless application can activate the connection-type application based on the data stored in the received notification message.

  The data connection establishment unit 102 establishes a data connection with the terminal device A 131 in response to the establishment request sent by the activated connection type application. Next, the relay unit 103 relays the data connection with the terminal device A131 and the data connection with the terminal device B132. As a result, communication in real time such as a messenger service is realized between the terminal device A131 and the terminal device B132.

  As described above, according to the online state control device according to the present embodiment, even if the terminal device A131 in which the connection type application is not activated is the other party, the connection type application makes a connection with the terminal device B132. Real-time communication will be possible. In addition, a real-time communication service such as a messenger service can be used more easily for a user without requiring a complicated operation procedure.

  Next, the operation (online state control method) of the online state control apparatus in the present embodiment will be described with reference to the flowchart of FIG. First, when the data connection establishment unit 102 receives a data connection establishment request (Y in step S201), in step S202, the data connection establishment unit 102 establishes a data connection with the terminal device that has accepted the request. Here, in the following, it is assumed that the data connection request from the terminal device B132 is accepted and the data connection is established, but the data connection request from the terminal device A131 is not accepted.

  Next, in step S203, the network connection determination unit 101 sends out the terminal device A131 and the terminal device B132 that are registered, or the terminal device A131 and the terminal device B132 that have a data connection establishment record, from the terminal device. It is determined from the connection confirmation information that the connection between the terminal device and the network is established. In step S203, for the terminal device A131 and the terminal device B132 that are determined to have established network connection (Y in step S203), in step S204, the data connection determination unit 104 determines the establishment of the data connection. In step S204, the terminal status setting unit 105 sets that the data connection is virtually established in step S205 for the terminal device A131 determined that the data connection has not been established (N in step S204). To do.

  Thereafter, when a data connection relay request by the terminal device B 132 is received for the virtual data connection of the terminal device A 131 that is set as having been virtually established (Y in step S206), the data connection establishment request The transmission notification unit 106 notifies the terminal device A 131 of transmission of a data connection establishment request. Thereafter, when a data connection establishment request is sent from the terminal device A131, the data connection establishment unit 102 establishes a data connection with the terminal device A131, and the relay unit 103 establishes a data connection with the terminal device A131, and The data connection with the terminal device B132 is relayed.

  When setting the virtual data connection, the type of the network (line) between the terminal device is determined, and if the network is a broadband, it is set that large-capacity data can be transmitted and received. If the network is a narrow band, It may be set that a large amount of data cannot be transmitted / received. The network bandwidth may be determined based on a set connection fee. Thus, by determining the bandwidth of the network, it is possible to limit the amount of data to be transmitted / received, and for example, it is possible to consider power saving in the terminal device. Further, the same determination as described above may be performed based on area information indicating the current position of the terminal device. These may be set separately by the user using the terminal device.

  Here, in the present invention, the network connection determination unit 101 determines that the connection between the terminal device and the network is established, and the data connection determination unit 104 establishes the data connection with the terminal device. The terminal state setting unit 105 determines that the connection is established by the network connection determination unit 101, and in addition, the data connection determination unit 104 determines that the data connection is not established. The terminal device thus set sets the data connection to be virtually established, and the data connection establishment request sending notification unit 106 is set by the terminal state setting unit 105 to set the data connection to be virtually established. Accepts a connection request for a virtual data connection of a terminal device It is important to notice the sending of establishment request over data connection.

  In other words, the present invention relates to a network connection determination unit 101 that determines that a connection between a terminal device and a network is established, and a data connection determination unit 104 that determines that a data connection with a terminal device is not established. In addition, the terminal device for which it is determined that the connection is established by the network connection determining unit 101 and that the data connection is not established by the data connection determining unit 104 is virtually connected to the terminal device. A terminal state setting unit 105 that is set to be established, and a request for connection to a virtual data connection of a terminal device that is set to be virtually established by the terminal state setting unit 105; Data that notifies the terminal device that a data connection establishment request has been sent It is important that a Nekushon establishment request sending notification unit 106.

  By providing these, according to the present invention, even if the terminal device in which the connection-type application is not activated is the other party, the connection-type application can perform real-time communication with the terminal device. For example, in response to a connection request to a terminal device from an application server that provides services such as providing content, the terminal state (virtual online state) set by the terminal state setting unit 105 is notified to the application server. Also good. Thereafter, if a data connection is established with the terminal by a notification from the data connection establishment request transmission notification unit 106, real-time content distribution from the application server becomes possible.

  When authentication is performed by the authentication unit 701 that has received the terminal ID, the wireless terminal device A 731 and the wireless terminal device B 732 can be connected to the wireless network 720. Further, this connection state is managed by the connection management unit 702. In the connection management unit 702, for example, in the table 702a, a terminal ID for identifying each wireless terminal device, a state indicating a network connection state, a type indicating a line bandwidth, and an area where a wireless terminal device exists ( A line state including (region) is provided for each wireless terminal device.

  Thus, in a state where the wireless terminal device A 731 and the wireless terminal device B 732 are connected to the wireless network 720, the data connection of the wireless terminal device B 732 as described later, and the data connection to the wireless terminal device A 731 are performed. Notification of establishment request transmission. These are the same as those in the fourth embodiment.

  The service server 900 includes a relay unit 901 that relays between established data connections, and a terminal state storage unit 902 that stores the terminal state notified from the proxy server 910. For example, the terminal state storage unit 902 indicates in the online state table 902a, together with user IDs (user1, user2) for identifying users using each wireless terminal device, that the large-capacity communication of each wireless terminal device is disabled. An online state including this is provided for each wireless terminal device.

  Next, the proxy server 910 first determines a connection between the wireless terminal device A731 and the wireless network 720 based on the connection confirmation information obtained from the network authentication server 700. 911. For example, the network connection determination unit 911 determines connection establishment with the wireless network 720 for the wireless terminal device A 731 and the wireless terminal device B 732 registered in advance. In addition, the network connection determination unit 911 determines connection establishment with the wireless network 720 for the wireless terminal device A 731 and the wireless terminal device B 732 in which data connection has been established in the past.

  As described above, the network connection determination unit 911 notifies the network authentication server 700 of the terminal ID of the wireless terminal device that is the connection determination target. In the network authentication server 700 that has received this notification, the terminal ID that has received the line status (network connection status) of the target wireless terminal device that is recognized (managed) by the connection management unit 702 in the connection status notification unit 703. At the same time, the proxy server 910 is notified.

  The proxy server 910 also establishes that the data connection establishment unit 912 establishes a data connection with the requesting wireless terminal device based on a request from the wireless terminal device, and the data connection establishment unit 912 establishes the data connection. A transfer unit 913 that notifies the service server 900 is provided.

  In this embodiment, for example, when a user activates a connection-type application on the wireless terminal device B 732, a data connection establishment request is sent to the wireless network 720 together with the user ID and terminal ID. This establishment request is accepted by the data connection establishment unit 912 via the wireless network 720. In response to this establishment request, the data connection establishment unit 912 establishes a data connection with the requesting wireless terminal device B 732 and brings it online. The proxy server 910 relays between the wireless terminal device thus established with the data connection and the service server 900.

  In the present embodiment, as described above, the relay unit 901 relays between each data connection in a state where the data connection with each wireless terminal device is established via the proxy server 910. Real-time communication such as a messenger service is realized between different wireless terminal devices.

  Further, the proxy server 910 determines that the connection with the wireless network 720 has been established by the data connection determination unit 914 that determines that the data connection with the wireless terminal device has not been established, and the network connection determination unit 911. In addition, the wireless terminal device determined that the data connection is not established by the data connection determination unit 914 includes a terminal state setting unit 915 that sets that the data connection is virtually established. Further, the terminal state setting unit 915 notifies the terminal state storage unit 902 of the service server 900 of the set terminal state.

  For example, it is assumed that the wireless terminal device A731, which is a mobile phone, exists in an area where communication is possible, but the connection-type application as described above is not activated. In this case, the network connection determination unit 911 determines that the wireless terminal device A 731 is connected to the wireless network 720. On the other hand, the data connection determination unit 914 determines that the data connection with the wireless terminal device A 731 has not been established. Accordingly, the terminal state setting unit 915 sets that the wireless terminal device A731 in the above-described state has virtually established a data connection.

  Further, the terminal state setting unit 915 includes, for example, a virtual online state, a wireless network area together with a user ID (user1, user2) and a terminal ID (terminal1, terminal2) for identifying each wireless terminal device in the online state table 915a. , Information on online notification area (Tokyo, all areas), network connection status (connectable), line bandwidth type (broadband), area where wireless terminal devices exist (Tokyo, Osaka) ) And an online state including the incapability of large-capacity communication are provided for each wireless terminal device.

  Further, the proxy server 910 relays the data connection by the wireless terminal device B 732 with respect to the virtual data connection of the wireless terminal device A 731 that is set to be virtually established by the terminal state setting unit 915, for example. A data connection establishment request transmission notification unit 916 that receives a request and notifies the wireless terminal device A 731 of transmission of a data connection establishment request is provided. The data connection establishment request transmission notification unit 916 notifies the wireless terminal device A731 of the transmission of the data connection establishment request by a connectionless application such as e-mail or a short message.

  As a result of this notification, the user of the wireless terminal device A731 or the connectionless application 751 starts the connection-type application 741 in the wireless terminal device A731, and the connection-type application 741 is operating. A request for establishing a data connection is sent from the device A731. In response to this request, the data connection establishment unit 912 establishes a data connection with the wireless terminal device A731. Next, the relay unit 901 relays the data connection with the wireless terminal device A 731 and the data connection with the wireless terminal device B 732. As a result, real-time communication such as a messenger service is realized between the wireless terminal device A 731 and the wireless terminal device B 732.

  As described above, according to the online state control system according to the present embodiment, even if the wireless terminal device A731 in which the connection type application is not activated is a partner, the connection type application establishes a connection with the wireless terminal device B732. Real-time communication between the two. In addition, a real-time communication service such as a messenger service can be used more easily for a user without requiring a complicated operation procedure.

  Note that the determination of the network connection of the terminal device, the determination of the data connection, and the setting of the terminal state may be performed regularly or at a set time. Further, when a request for establishing a data connection is received, determination of the network connection of the terminal device, determination of the data connection, and setting of the terminal state may be performed.

  The above-described online control device and each server are computer devices including a CPU, a main storage device, an external storage device, a network connection device, and the like, and the CPU is operated by a program developed in the main storage device. Each function described above is realized.

  For example, the online control device has a network connection determination function for determining that a connection between the terminal device and the network is established, a data connection determination function for determining that a data connection with the terminal device is not established, A terminal device for which it is determined that a connection has been established by the network connection determination function and, in addition, a data connection that has not been established by the data connection determination function has a virtual data connection established. The terminal status setting function to be set and the terminal status setting function to accept a connection request for the virtual data connection of the terminal device that is set to be virtually established, and the terminal device Establish data connection to notify establishment request transmission It can be realized by executing a program and a delivery notification function to the computer.

  Each function may be distributed to a plurality of computer devices (servers). For example, network connection determination, data connection establishment determination, terminal state setting, and data connection establishment request transmission notification may be performed by different servers. Further, network connection determination, data connection establishment determination, terminal state setting, and data connection establishment request transmission notification may all be performed by different servers.

  Conventionally, for example, a connection-type application that operates on a wireless terminal has a problem that it cannot communicate with other terminals in real time because the connection cannot always be maintained due to power supply and cost problems. On the other hand, in the present invention, it is determined whether the terminal device exists in the network area and the connection can be established immediately, and if it can be established, even if the connection is disconnected, it is virtually online. Therefore, it is now possible to communicate with other terminals in real time without maintaining a connection at all times.

  For example, when a connection-type application does not maintain a connection, there is a technique that is uniformly regarded as a virtual online state. On the other hand, in the present invention, a connection is immediately established based on the network connection state of the terminal device. The only difference is that it is virtually online only when possible. As described above, the most important feature of the present invention is that the network connection information of the terminal device is used for determining whether or not the virtual online state should be set.

  In the present invention described above, for example, since the network authentication server notifies the service server whether or not a terminal device such as a wireless terminal exists in a network area such as a wireless network, the service server can set a connection by the wireless terminal. The virtual online state can be realized only when it is possible to know whether or not the communication is in real time. As a result, even a terminal device that has not activated a connection-type application can communicate in real time.

  Also, for example, since the network authentication server notifies the service server of the line type and bandwidth information of the wireless network in which the wireless terminal is accommodated, the service server determines the communication means suitable for the bandwidth that the wireless terminal can transmit and receive It can be known to the terminal, and other terminals can send messages using appropriate communication means. This eliminates the need for the user to consider possible communication means.

  Also, for example, since the network authentication server notifies the service server of the area where the wireless terminal exists, the service server can inform the other wireless terminals of the virtual online state only in the area requested by the user. Become. Alternatively, the service server may limit the choices of possible communication means in consideration of the band that can be transmitted and received by the wireless terminal. This eliminates the need for the user to initiate unwanted communication. Thus, according to the present invention, the convenience of the communication application in the terminal device is improved.
