In the embodiment, the portable terminal is described using a wristwatch. However, in addition to the wristwatch 100, the portable terminal can be a portable terminal such as a PDA, a notebook computer, or a mobile phone.

(Embodiment 1)
FIG. 1 is a schematic diagram showing an information distribution system according to Embodiment 1 of the present invention. As shown in FIG. 1, the information distribution system 1 according to this embodiment includes a wristwatch 100 that is a mobile terminal, a mobile phone 200 that is connected to the wristwatch 100 via a wireless communication line 10, and a wireless telephone line 20. A base station 50 connected to the mobile phone 200 and a plurality of information distribution servers 300A to 300N connected to the base station 50 via the network communication line 30. A plurality of connection terminals 400A to 400N are connected to the mobile phone 200 and the information distribution servers 300A to 300N via the network communication line 30. By constructing the information distribution system 1 in this way, as described below, it is possible to automatically acquire the connection information of the connection person currently connected to the information distribution servers 300A to 300N, and The mobile terminal can acquire the change information with high real-time property and can notify the user of the mobile terminal.

  First, the information distribution servers 300A to 300N will be described. Since these information distribution servers 300A to 300N have the same configuration, only the information distribution server 300A will be described below. As shown in FIG. 2, the information distribution server 300 </ b> A includes first communication means 301, connection person authentication means 302, connection person information storage means 303, and clock means 310.

  The information distribution server 300A connects to the base station 50, the connection terminals 400A to 400N, the other information distribution servers 300B to 300N, and the like through the first communication unit 301, and inputs and outputs data.

  In the information distribution server 300A, the connecting person authenticating unit 302 specifies a connecting person who is accessing the information distributing server 300A using any of the plurality of connecting terminals 400A to 400N. When the connection terminals 400A to 400N access the information distribution server 300A, the information distribution server 300A acquires the ID of the connection person (connection person ID) and the password (connection person password) from the accessed connection terminal. Then, the acquired connection ID and connection password are input to the connection authentication unit 302.

  The connection authorization unit 302 includes a user storage unit, a search unit, and a comparison unit. The user storage means stores the ID of the connected person and the password corresponding to the ID in advance. For example, a pointer can be added to an ID and stored in a memory, and a password can be stored in a memory address designated by the pointer, so that the ID and the password can be stored in association with each other. Alternatively, the password may be added to the ID and stored. The connection ID input to the connection authentication unit 302 is input to the search unit. The connection password input to the connection person authentication unit 302 is input to the comparison unit. When the connection means ID is input, the search means searches the user storage means for a password corresponding to the same ID as the connection ID, and outputs the searched password (search result password) to the comparison means. The comparing means compares the connection person password and the search result password to determine whether they match or do not match. The connection authorization unit 302 outputs to the first communication unit an output that permits access to the connected terminal if the comparison unit makes a match, and denies access to the connected terminal if the comparison does not match. The connection terminal to which access is permitted inputs / outputs information to / from the information distribution server 300A.

  In addition, the information distribution server 300A can store that the connection person specified by the connection person authentication unit 302 is accessing the information distribution server 300A by the connection person information storage unit 303. As the connected person information storage means 303, a memory, a hard disk, or the like can be allocated. When the access to the information distribution server 300A of the connection person specified by the connection person authentication means 302 is completed, the information distribution server 300A reads the connection person from the connection person information storage means 303. Can store the fact that the access to the information distribution server 300A has been completed. For example, by storing the ID of the accessing user in the connecting person information storage unit 303, it is stored that the connecting person specified by the connecting person authentication unit 302 is accessing the information distribution server 300A. By deleting the ID of the connecting user who is accessing from the connecting person information storage unit 303, it is stored that the connecting person specified by the connecting person authentication unit 302 has completed access from the information distribution server 300A. be able to. At this time, as another aspect, a connection flag indicating whether or not access is provided is provided, and an ON / OFF state of the flag indicates an access state and a non-access state, and the connection flag is sent to the connected person information storage unit 303. It can be added to the ID and stored. As another aspect, when storing in the connected person information storage means 303 that the connected person specified by the connected person authentication means 302 is accessing the information distribution server 300A, or the access has been completed, The time is extracted from the clock means 310 and stored in the connection person information storage means 303 in correspondence with the ID of the connection person. This way you can see who connected. For example, by adding a pointer to the ID and storing it, and storing the time at the memory address designated by the pointer, the ID and the time can be stored in correspondence with each other, and they can be searched for each other. Alternatively, the time may be added to the ID and stored.

  The operation of the connected person information storage unit 303 will be described using the flowchart shown in FIG. When any of the connection terminals 400A to 400N starts to access the information distribution server 300A (S1-1), the connection terminals 400A to 400N that have started access from the information distribution server are requested to input the ID and password of the connection person. It is done. When the connection person inputs the ID and password from the connection terminal that has started the access, the connection person ID and password are transmitted from the connection terminal to the information distribution server 300A (S1-2).

  Then, when the information distribution server 300A receives the connection ID and password, the connection authentication unit 302 uses the connected user authentication unit 302 in advance to authenticate the connection person to be accessed. It is determined whether or not the password matches the password stored in the storage means (S1-3). If the input password does not match the previously stored password, the process returns to step S1-2. On the other hand, if the input password matches the password stored in advance, it is determined that the connecting person who wants to access may permit the access, and “currently, the connecting person is the information distribution server. The connected person information “accessing 300A” is stored in the connected person information storage means 303 (S1-4).

  Then, when the connected person ends the access to the information distribution server 300A (S1-5), the connected person information storage means 303 indicates that “currently, the connected person has finished accessing the information distribution server 300A. Is stored (S1-6).

  The information distribution server 300A can synchronize the time of the information distribution server 300A with the time of the wristwatch 100 and the time of the mobile phone 200, which will be described later, by the clock means 310. For example, access between the information distribution server 300A and the mobile phone 200 is permitted, and the information distribution server 300A reads the time information from the clock unit 310 and transmits the time information to the mobile phone 200. The cellular phone 200 can synchronize the time by correcting the time obtained by adding the communication delay time to the received time information as the current time of the clock means 210 of the cellular phone 200. By performing the same process between other devices, the time of the clock means can be synchronized between the devices.

  Next, the information distribution servers 300 </ b> A to 300 </ b> N described above are connected to the mobile phone 200 via the base station 50, and the connection information possessed by the information distribution servers 300 </ b> A to 300 </ b> N is transmitted to the mobile phone 200.

It is possible to acquire connection person information of a connecting person who is accessing and transmit the obtained connection person information to the wristwatch 100. Hereinafter, the base station 50 is a device for connecting the mobile phone 200 and the network communication line 30. The information distribution server list 206 is data in which URLs (Uniform Resource Locations) of the information distribution servers 300 </ b> A to 300 </ b> N are written, and are stored in a memory built in the mobile phone 200.

  The first wireless communication unit 201 is connected to the second wireless communication unit 101 of the wristwatch 100 described later by wireless communication, that is, the wireless communication line 10. When the first wireless communication unit 201 and the second wireless communication unit 201 are connected by the wireless communication line 10, the mobile phone 200 and the wristwatch 100 input / output data to / from each other. For example, the first wireless communication unit 201 and the second wireless communication unit 201 can use short-range wireless communication units such as Bluetooth.

  The wireless telephone communication means 202 is means for performing mobile phone communication with the base station 50, and is a wireless telephone line 20 between the mobile phone 200 and the base station 50. When the mobile phone 200 and the base station 50 are connected by the radio telephone line 20, data is input / output to / from each other. The radio telephone communication means 202 is connected to the information distribution servers 300A to 300N, the connection terminals 400A to 400N, the other information distribution servers 300B, etc. via the radio telephone line 20 and the network communication line 30 with the base station 50, and the information I / O is performed.

  The connected person information acquisition unit 203 extracts the URLs of the information distribution servers 300 </ b> A to 300 </ b> N in the information distribution server list 206 from the memory and outputs them to the information distribution server connection unit 205. Further, the connection person information acquisition unit 203 outputs an instruction to connect the information distribution server specified by the extracted URL to the information distribution server connection unit 205 and the mobile phone 200. Here, URL extraction is performed in the order registered in the memory. At this time, as another form, priority order data may be added to URL data in advance, and extraction may be performed according to the priority order.

  The information distribution server connection unit 205 connects to the information distribution server specified by the extracted URL in accordance with an instruction from the connection person information acquisition unit 203. First, the mobile phone 200 and the base station 50 are connected by the radio telephone line 20, and connected to the information distribution server of the URL designated by the network communication line 30 ahead, thereby enabling data input / output.

  The timer unit 207 is a timer unit that outputs an interrupt signal periodically at a time interval when a time interval is set.

  The connected person information notifying means 204 is a means for outputting the connected person information stored in the connected person information acquiring means 203 to the wristwatch 100. The connection information notifying unit 204 operates the first communication unit 201 to connect the wristwatch 100 and the mobile phone 200 via the wireless communication line 10 so that data can be input / output mutually. Then, the connected person information notifying unit 204 instructs the connected person information acquiring unit 203 to output the stored connected person information to the wristwatch 100. When an instruction to output the stored connection person information to the wristwatch 100 is input, the connection person information acquisition unit 203 outputs the connection person information to the wristwatch 100 via the wireless communication line 10.

  FIG. 5 is a diagram illustrating a sequence in which the mobile phone 200 acquires connection information of a user who is accessing the information distribution servers 300A to 300N. As shown in FIG. 5, first, the connected person information acquisition unit 203 extracts one of the URLs of the information distribution servers 300A to 300N in the information distribution server list 206 stored from the memory of the mobile phone 200 (S2- 1). Next, the extracted URL is output to the information distribution server connection unit 205. (S2-2).

  Then, the information distribution server connection unit 205 operates the wireless telephone communication unit 202 to connect the mobile phone 200 to the information distribution servers 300A to 300N through the base station 50 and the network communication line 30. To do. Then, the information distribution server connection unit 205 connects to the information distribution server specified by the extracted URL, and enables data input / output between the information distribution server and the mobile phone 200 (S2-3). .

  Then, the connected person information acquisition unit 203 outputs the connected person information stored in the connected person information storage unit 303 of the information distribution server to the connected person information acquisition unit 203 for the connected information distribution server. To make a request. When the information distribution server receives the request, the information distribution server outputs the connection person information stored in the connection person information storage unit 303 to the connection person information acquisition unit 203. The connected person information acquisition means 203 inputs and stores the connected person information. That is, the connected person information is transmitted from the information distribution server 300A to the mobile phone 200 (S2-4).

  Then, the above-described steps S2-1 to S2-3 are performed on all the information distribution servers 300A to 300N written in the information distribution server list 206 (S2-5).

  Next, the connection person information notification unit 204 operates the first wireless communication unit 201 to enable communication between the mobile phone 200 and the wristwatch 100. Then, the connected person information notifying unit 204 causes the connected person information acquiring unit 203 to output the connected person information stored in the connected person information acquiring unit 203 to the wristwatch 100. The connection person information transmitted to the mobile phone 200 in this way is transmitted to the wristwatch 100 by the connection person information notifying unit 204 of the mobile phone 200 using the first wireless communication unit 201 (S2-6).

  Steps S2-1 to S2-6 described above are periodically performed by the timer means 207. The timer means 207 outputs an instruction to operate the connected person information acquisition means 203 at a time interval of 10 minutes. The time interval can be changed to a predetermined value by setting. The shorter the time interval, the better the system. Note that the mobile phone 200 synchronizes the time of the mobile phone 200 with the time of the wristwatch 100 and the time of the information distribution servers 300A to 300N in the same manner as the clock means 310 of the information distribution server 300A. Can be done.

  Next, the connection information transmitted from the mobile phone 200 is received by the wristwatch 100. FIG. 6 is a schematic diagram of the wristwatch 100. As shown in FIG. 6, the wristwatch 100 includes a second wireless communication unit 101, a display unit 102, a notification unit 103, a filtering unit 104, a clock unit 110, an input unit 111, and a control unit 120. These are controlled by the control means 120. The wristwatch 100 can display the received connection information by the display means 102. Here, in this embodiment, since the wristwatch 100 is used as the portable terminal, there is an effect that the user of the wristwatch 100 can easily and immediately confirm the received connection information.

  The second wireless communication unit 101 is a wireless communication unit that communicates with the first wireless communication unit 201, and is a short-range wireless communication unit such as Bluetooth. The display means 102 is, for example, a liquid crystal display device. The wristwatch 100 can inform the user of the wristwatch 100 that the connection information has been received by the notification means 103. When the wristwatch 100 receives the connection information from the mobile phone 200, the wristwatch 100 drives the notification unit 103. Examples of the notification unit 103 include a vibration motor, a warning lamp, and a speaker.

  Further, the wristwatch 100 can display only important connection information by the filtering means 104. That is, for example, as the filtering unit 104, a priority order is set in advance for the information distribution servers 300A to 300N, and a search unit for searching according to the instructed condition is provided, and the search result is displayed on the display unit 102. When the maximum amount of connection information to be displayed is set, among the connection information transmitted from the mobile phone 200, the connection person of the information distribution server having a high priority within the range of the maximum amount Only information can be retrieved and displayed on the display means 102. By using such filtering means 104, the wristwatch 100 can display only the connection information of the information distribution server having a high priority to the wristwatch user.

  Note that the wristwatch 100 can synchronize the time of the wristwatch 100 with the time of the mobile phone 200 and the time of the information delivery servers 300A to 300N by the clock means 110, similarly to the clock means 310 of the information delivery server 300A described above. It can be done. In addition, the wristwatch 100 can input information related to the wristwatch 100 by the input unit 111. For example, the setting of the filtering means 104 described above can be input.

  When the wristwatch 100 receives the connection information transmitted from the mobile phone 200. Connecter information is input to the control means 120 of the wristwatch 100. The control means 120 outputs the input connection person information to the display means 102, and the display means 102 displays the connection person information. At this time, in order to confirm the filtering setting of the filtering unit 104, the control unit 120 outputs a request signal for outputting the filtering setting information to the control unit 120 to the filtering unit 104. When the received filtering unit 104 outputs the filtering setting to the control unit 120 and the control unit 120 inputs the filtering setting, the control unit 120 performs the filtering process according to the setting.

  In addition to password authentication, another form of the connection person authentication means 302 includes biometric authentication such as fingerprint authentication and iris authentication.

  Further, since the filtering means 104 can process the transmitted connection information as set in advance, in addition to the above, for example, the priority of the information distribution server and the wristwatch 100 are previously set. The minimum operating power supply voltage is set, the power supply voltage of the wristwatch 100 is periodically measured, and when the minimum operating power supply voltage is reached, the connection information transmitted from the mobile phone 200 is assigned the priority order. For example, a program that processes only the connection information of the upper three information distribution servers. Finally, the processed connection information is displayed on the display means 102.
