(Embodiment)
FIG. 1 is a schematic diagram of a communication system 100 according to an embodiment of the present invention. The outline of the present embodiment will be described with reference to FIG.

  A method of communication between the communication terminal apparatus 101 and the center side apparatus 102 will be described. The communication terminal apparatus 101 communicates with the center side apparatus 102 via the surrounding base station apparatus.

  Now, it is assumed that the communication terminal apparatus 101 is communicating with the base station apparatus 103 having a communication tower. The base station apparatus 103 is connected to the base station apparatus 104 via a high-speed communication line 105 using a wired line such as a microwave line or an optical fiber.

  The center side device 102 is assumed to be connected to the base station device 104. As a result, the center side apparatus 102 can communicate with the communication terminal apparatus 101 via the high speed communication line 105 at low and high desired communication speeds.

  A communication terminal device 101 such as a mobile phone terminal possessed by a user can always communicate with the center side device 102, and in addition, can transmit a command to the center side device 102 to request assistance from itself. . Further, the communication terminal device 101 has a built-in imaging camera, and can always store imaging information up to a predetermined time before and transmit the imaging information to the center side device 102 by a user's operation.

  Now, assume that the user is visually impaired. When the communication terminal device 101 makes a setting indicating that the user desires support according to the setting of the user, it is considered that the user is in a smooth state immediately after the setting, and thus a signal indicating that the communication terminal device 101 is normally “smooth” Is transmitted to the center side apparatus 102 at a low transmission speed.

  Now, assume that the user senses some emergency and operates the communication terminal device 101. By this operation, the communication terminal apparatus 101 sends the stored information about the past certain period and the current imaging information to the center side apparatus 102 together with a signal indicating that an “emergency has occurred” to the center side apparatus 102. Send to.

  Next, the server device 106 of the center side device 102 stores the imaging information transmitted from the communication terminal device 101. Further, the center side apparatus 102 creates support information effective for support such as related information of the corresponding user together with the imaging information, and transmits the support information to the small computer 108 of the monitoring center 107. This support information includes the arrangement information of the monitoring camera device when a monitoring camera device capable of imaging the vicinity of the place where the corresponding user exists is arranged. As a result, the imaging information and the related information of the corresponding user are displayed on the display screen 109 of the small computer 108.

  Next, the support operator of the monitoring center 107 transmits a command signal to the center side apparatus 102 by the small computer apparatus 108 to the effect that the imaging information of the monitoring camera apparatus 110 that is supposed to image the corresponding user should be transmitted. To do.

  Next, the center side apparatus 102 commands the monitoring camera apparatus 110 that is supposed to image the user to transmit imaging information. Accordingly, the monitoring camera device 110 transmits the imaging information to the center side device 102 in real time and at a high communication speed. The center side device 102 transmits this imaging information to the small computer device 108 of the monitoring center 107.

  As a result, on the screen 109 of the small computer apparatus 108, imaging information including the corresponding user and indicating the surrounding situation is displayed together. Note that the imaging information may not include the corresponding user depending on the shooting direction of the monitoring camera device 110.

  Next, the support operator of the monitoring center 107 confirms by looking at the screen 109 of the small computer device 108 and, for example, “confirmed. There is a dog nearby. Support information for the user such as “.” Is input to the small computer device 108 using a microphone, for example, and output to the center side device 102. The voice support information is transmitted to the communication terminal device 101 of the user by the center side device 102.

  As described above, in the communication system according to the present embodiment, the user of communication terminal apparatus 101 communicates with center-side apparatus 102 or monitoring center 107 and receives support during a predetermined period for which support is desired. Can do. In addition, the support operator of the monitoring center 107 not only sees the current imaging information output by the camera device or the monitoring camera device 110 of the communication terminal device 101, but also immediately before the emergency situation stored in the communication terminal device 101 occurs. Since it can be confirmed including imaging information for a certain period, in addition to the support automatically performed by the center side apparatus 102, more advanced and accurate support can be performed for the user of the communication terminal apparatus 101.

  In the above description, the monitoring camera device 110 is selected by the support operator of the monitoring center 107. However, this selection is automatically performed by the center side device 102 based on the current position of the user. You may make it perform. In a case where a monitoring target can be captured almost certainly such as a place where a large number of monitoring camera devices are arranged such as in a downtown area, even if it is automatic, imaging including the user of the target communication terminal device 101 Since there is a high possibility of acquiring information, it is possible to provide more accurate and accurate user support in combination with support from the support operator.

  In addition, when the screen 109 of the small computer device 108 is small, a large display device can be provided.

  FIG. 2 is a block diagram showing a configuration of communication terminal apparatus 200 according to the embodiment of the present invention.

  The communication terminal device 200 is equivalent to the communication terminal device 101 of FIG.

  The monitored registration unit 201 operates the user to output a support request signal indicating that the user wants monitoring to be performed to the transmission control unit 202.

  The transmission control unit 202 outputs to the low-speed transmission unit 203 a signal indicating that the operation is “smooth” at the initial normal time when the user operates the monitored registration unit 201 (information indicating the user status in the normal state). In addition, the transmission control unit 202 inputs the current video information from the camera unit 206 in the event of an emergency when the user operates the emergency operation unit 208, and the past video information stored in the nonvolatile memory unit 207, which will be described later. Is input and output to the high-speed transmission unit 209.

  The low-speed transmission unit 203 wirelessly transmits a signal indicating “smooth” as a low-speed transmission signal by modulating the signal with a modulation method with a small number of modulation multi-values or by encoding with a coding method with a low coding rate. The data is output to the transmission unit 204. The wireless transmission unit 204 wirelessly processes and transmits a low-speed signal indicating “normal” in normal time and a high-speed signal that is emergency imaging information. The terminal function unit 205 performs input / output to / from the communication terminal device 200 by a user operation. The camera unit 206 images the imaging target and outputs imaging information. The camera unit 206 also outputs audio information synchronized with the imaging information together with the imaging information. Therefore, in the following description, the imaging information includes audio information unless otherwise specified.

  The nonvolatile memory unit 207 stores imaging information output from the camera unit 206. The emergency operation unit 208 outputs an emergency signal to the transmission control unit 202 when operated by the user when an emergency occurs. The high-speed transmission unit 209 employs a modulation method with a large number of modulation multi-values and a coding method with a large coding rate, and can perform high-speed transmission. In an emergency, the current image pickup information from the transmission control unit 202 and the past The imaging information is output to the wireless transmission unit 204. The past video information output by the high-speed transmission unit 209 includes imaging information after a time 30 seconds after detecting an emergency, or imaging information for a predetermined time (for example, 30 seconds) before detecting an emergency state, etc. It is. In the case of the present embodiment, the imaging information sent from the transmission control unit 202 to the high-speed transmission unit 209 is 30 frames per second, like a normal television signal.

  FIG. 3 is a block diagram showing the configuration of the server device 300 and the monitoring center 350. The server device 300 corresponds to the server device 106 in FIG. 1, and the monitoring center 350 corresponds to the monitoring center 107 in FIG.

  The server apparatus 300 mainly includes a transmission / reception unit 301, a server control unit 302, a monitoring center I / F (interface) unit 303, a monitoring camera control unit 304, and a communication control unit 305.

  The transmission / reception unit 301 transmits / receives signals to / from external and internal units (such as the server control unit 302). Specifically, the transmission / reception unit 301 transmits a support request signal, a terminal number of the communication terminal apparatus 200, an emergency notification signal, for example, imaging information for the past 30 seconds and current imaging information, which are wirelessly transmitted by the communication terminal apparatus 200 of FIG. Receive and output to the server control unit 302. The transmission / reception unit 301 also receives related information such as the base station number of the base station device with which the communication terminal device 200 of FIG. 2 has communicated, and outputs it to the server control unit 302.

  The server control unit 302 is based on information input from the transmission / reception unit 301 and the monitoring center I / F unit 303 described later, and the monitoring camera control unit 304, the communication control unit 305, the transmission / reception unit 301, and the monitoring center I / F unit 303. Input / output operation commands and necessary information.

  Specifically, the server control unit 302 installs a plurality of monitoring cameras 110 (a plurality of monitoring cameras 110) shown in FIG. 1 with respect to the monitoring camera control unit 304 when an emergency situation occurs in the user. However, only one unit is shown in FIG. 1), information for identifying the monitoring camera related to the position where the user is staying is generated. That is, each surveillance camera belongs to a cell formed by the base station apparatus (see 103 and 104 in FIG. 1). The administrator of the communication system according to the present embodiment knows in advance where the surveillance camera is located in the cell, and in many cases, to identify the cell to which each surveillance camera belongs. Using the cell identification information (for example, cell ID) that is the information of the monitoring camera, the identification number of each monitoring camera and the cell ID are associated with each other to confirm the position of the monitoring camera. Correspondingly, the server control unit 302 has a table in which the positions of all the monitoring cameras are stored in advance in association with the cell IDs. When an emergency situation occurs in the user, the base station information including the cell ID indicating the cell is stored in the server from the base station device of the cell to which the point belongs to the position of the communication terminal device possessed by the user. The data is transmitted to the device 300 and received by the transmission / reception unit 301. The received cell ID is output to the server control unit 302. As a result, the server control unit 302 refers to the table, selects the monitoring camera corresponding to the cell ID indicating the position of the user where the emergency occurred, and generates the number of the corresponding monitoring camera. When the monitoring camera to be activated is specified in this way, the server apparatus 302 outputs the number of the corresponding monitoring camera to the monitoring camera control unit 304, and outputs a command signal for causing the monitoring camera to transmit imaging information. To do.

  In addition, when an emergency occurs in the user, the server control unit 302 receives the imaging information transmitted by the communication terminal device at a high communication speed with respect to the communication control unit 305 or the corresponding monitoring camera In order to receive the imaging information to be transmitted at a high communication speed, the line priority for the communication terminal device or the monitoring camera is increased by narrowing the communication band for the communication terminal device used by other users. The command signal to command is output.

  Further, the server control unit 302 wirelessly transmits a support request signal, a terminal number of the communication terminal apparatus 200, an emergency notification signal, for example, imaging information for the past 30 seconds, current imaging information, Related information such as the base station number of the base station apparatus with which the communication terminal apparatus 200 of FIG. 2 is communicating is output to the monitoring center 350 via the monitoring center I / F unit 303. This is because it is easier for the support operator of the monitoring center to confirm the user's situation by visual recognition or the like.

  The monitoring camera control unit 304 outputs a corresponding camera activation signal that instructs the corresponding monitoring camera designated by the server control unit 302 to transmit imaging information to the transmission / reception unit 301.

  The communication control unit 305 requests to increase the line speed for the corresponding communication terminal device or the corresponding monitoring camera that has transmitted the occurrence of an emergency to the user according to the command signal from the server control unit 302. A line speed switching request signal is output to the transmission / reception unit 301.

  The transmission / reception unit 301 receives a corresponding camera activation signal from the monitoring camera control unit 304 or a line speed switching request signal from the communication control unit 305, and is communicating with the corresponding monitoring camera or the corresponding communication terminal device in FIG. The communication line speed switching signal is output to the base station apparatus 104 constituting the high-speed communication line 105 for the base station apparatus 103 and the center side apparatus 102 shown in FIG. As a result, the base station device 103, the base station device 104, and the server device 106 of the center side device 102 shown in FIG. 1 are switched from the previous low-speed communication line state to the high-speed communication line state. That is, the priority as a line is set high.

  The monitoring center 350 includes a small computer device 351 and a large display unit 352. The small computer device 351 inputs and outputs signals to and from the server device 300 via the monitoring center I / F unit 303. The large display unit 352 displays information obtained via the small computer device 351 on a large screen.

  Next, the operation of communication terminal apparatus 200 will be described.

  Assume that when going out, the user operates the monitored registration unit 201 and sets that he wants to receive support along with his destination information. The contents set by the user by operating the monitored registration unit 201 are output to the transmission control unit 202 as a support request signal. Here, the support request signal means that the user of the communication terminal device 200 has gone out and registered in the center side device 102 of FIG. 1, and after that, when the user has notified the emergency situation, A signal that plays a role of registering that the center side device 102 in FIG. However, when the user goes out and generates this support request signal, the user does not have any problem, that is, an emergency. Accordingly, the support request signal at this time is handled as a signal for notifying that the user is “smooth” in the server apparatus 300 and the monitoring center 350 in FIG. 3.

  The transmission control unit 202 inputs a signal from the monitored registration unit 201 and outputs a support request signal to the low-speed transmission unit 203. The low-speed transmission unit 203 outputs the support request signal to the wireless transmission unit 204 as a low-speed transmission signal.

  The wireless transmission unit 204 performs wireless transmission processing such as up-conversion on the input support request signal and transmits the signal to the outside. At this time, the wireless transmission unit 204 inputs the terminal number of the communication terminal device 200 from the terminal function unit 205 and wirelessly transmits it together with the destination information.

  The radio signal transmitted from the radio transmission unit 204 is received by the corresponding base station apparatus. In this way, the base station apparatus that has received the radio signal from communication terminal apparatus 200 uses the base station number that identifies itself as the destination information of the user and the terminal number of communication terminal apparatus 200 received from radio transmission section 204. (Including the cell ID) is added to the center side apparatus 102 of FIG. As a result, the center side apparatus 102 determines the relevant information (terminal number, base station number (including cell ID) of the base station apparatus) and the current location information and destination information of the user of the communication terminal apparatus 200 that requested this support. )

  In addition, the transmission control unit 202 that has received the support request signal from the monitored registration unit 201 activates the camera unit 206 and commands imaging.

  The camera unit 206 instructed to capture images from the transmission control unit 202 starts imaging, and sequentially updates and records, for example, 30-second imaging information in the nonvolatile memory unit 207. Thereby, after setting that the user wants to receive support, the communication terminal apparatus 200 repeatedly stores the image in the imaging direction arbitrarily set by the user in the nonvolatile memory unit 207 for at least the last 30 seconds. To do. The nonvolatile memory unit 207 normally has a capacity of several M (megabytes) or more, and can store imaging information and audio information collected during imaging for several hours if necessary.

  Assume that the user recognizes an emergency situation and operates the emergency operation unit 208 to notify the emergency situation. Accordingly, the emergency operation unit 208 outputs an emergency notification signal to the transmission control unit 202.

  The transmission control unit 202 that has received the emergency notification signal from the emergency operation unit 208 outputs an emergency occurrence signal to the camera unit 206.

  The camera unit 206 that has input the emergency occurrence signal stops the update storage operation to the non-volatile memory unit 207 and starts a higher-definition imaging operation than previously determined, and shows how it currently occurs. The imaging information is output to the transmission control unit 202.

  Further, the transmission control unit 202 inputs imaging information from when the emergency occurred from the nonvolatile memory unit 207, for example, after the past 30 seconds. Thereby, the transmission control unit 202, the emergency notification signal indicating that the user has recognized that an emergency has occurred, the imaging information of the last 30 seconds and the current imaging information of the imaging density of 30 frames per second, Is output to the high-speed transmission unit 209. Accordingly, the high-speed transmission unit 209 outputs the emergency notification signal, the imaging information for the past 30 seconds at 30 frames per second, and the current imaging information to the wireless transmission unit 204 as a high-speed transmission signal.

  The wireless transmission unit 204 performs wireless transmission processing such as up-conversion on the input emergency notification signal, imaging information for the past 30 seconds, and current imaging information, and transmits them to the outside. At this time, the wireless transmission unit 204 wirelessly transmits the terminal number of the communication terminal device 200 together. In this case, the destination information of the user may be wirelessly transmitted together. This is to cope with the case where the user changes the destination.

  As described above, the user uses the communication terminal device 200 to transmit a support request or occurrence of an emergency to the server device 300 shown in FIG.

  Next, operations of the server device 300 and the monitoring center 350 will be described.

  Before receiving the emergency notification signal from the communication terminal device 200, the server control unit 302 monitors the current location of the user indicated by the terminal number, the destination, and the base station number of the communication terminal device 200 of the corresponding user. The data is output to the monitoring center 350 via the center I / F unit 303. In response to this, the small computer device 351 of the monitoring center 350 displays the terminal number (including the user's name), the destination information, and the current position on the screen. From this display, the support operator of the monitoring center 350 confirms that the corresponding user is requesting support and that the user is proceeding smoothly toward the destination at that time. .

  Assume that an emergency situation has occurred in the user and the user has operated the emergency operation unit 208 in FIG. Along with this operation, the transmission / reception unit 301 receives the terminal number (including the user's name) of the communication terminal device 200, the emergency notification signal, the imaging information for the past 30 seconds, and the current imaging information, and sets the corresponding base station number. And output to the server control unit 302.

  The server control unit 302 outputs, to the monitoring camera control unit 304, a transmission command signal for, for example, the monitoring camera 110 in FIG. 1 around the user according to the current position information of the user indicated by the corresponding base station number.

  The monitoring camera control unit 304 instructs the corresponding monitoring camera to transmit imaging information via the transmission / reception unit 301. In response to this, the corresponding monitoring camera transmits imaging information at that time to the server apparatus 300.

  Accordingly, the transmission / reception unit 301 receives imaging information transmitted by the corresponding monitoring camera. In general, there are a plurality of corresponding monitoring cameras. In this case, the transmission / reception unit 301 receives imaging signals from the plurality of monitoring cameras and outputs them to the server control unit 302.

  Next, the server control unit 302 includes a user name indicated by the terminal number of the communication terminal device, an emergency notification signal, imaging information for the past 30 seconds, current imaging information, current location information of the user indicated by the corresponding base station number, The imaging information at that time of the corresponding monitoring camera is output to the monitoring center 350 via the monitoring center I / F unit 303.

  Correspondingly, the small computer device 351 of the monitoring center 350 indicates that the user name (including the terminal number if necessary), the user has an emergency, and the user is requesting assistance. Imaging information for the past 30 seconds, current imaging information, current location information of the user indicating which base station device the communication terminal device 200 possessed by the user is under, and imaging information at that time of the corresponding monitoring camera Is displayed. When there is a lot of information to be displayed, the support operator of the monitoring center 350 can display the large display unit 352 by operating the small computer device 351.

  In such a case, the support operator confirms the display on the small computer device 351 or the large display unit 352 while monitoring the support information using the input device of the small computer device 351 such as a microphone or a keyboard. Through the / F unit 303, the server control unit 302, the transmission / reception unit 301, etc., more accurate and advanced support is provided for users in an emergency based on their own judgment.

  When the communication capacity needs to be controlled due to a large amount of imaging information from the monitoring camera or the camera unit of the user's communication terminal device, the server control unit 302 performs an allowable delay in addition to the priority control of the communication line. It is also possible to output a control signal including time control to the communication control unit 305. The communication control unit 305 outputs a communication line control signal corresponding to the control signal including the allowable delay time control input from the server control unit 302 to the transmission / reception unit 301.

  Specifically, the communication terminal device 200 outputs a command for increasing the priority for the monitoring camera of the high-speed communication line 105 in FIG. 1 to the base station device 104 in FIG. Since the high-speed communication line 105 in FIG. 1 is originally secured to have a large communication capacity, the communication system 100 in FIG. 1 is, for example, a monitoring camera that captures the situation of a user who is in an emergency most accurately. Increase the line capacity. As a result, the status of the user imaged by the corresponding camera is displayed on the small computer device 351 and the large display unit 352 of the monitoring center 350 without difficulty with high-definition information. This increases the possibility that the support operator of the monitoring center 350 can more accurately support a user in an emergency.

  Note that the communication control by the communication control unit 305 is performed by the server control unit 302 by receiving an instruction signal from the operator of the monitoring center 350 via the small computer device 351 and the monitoring center I / F unit 303. Based on the imaging information of the past 30 seconds, the current imaging information, the current position information of the user indicated by the corresponding base station number, the imaging information at the time of the corresponding monitoring camera, etc. received by the control unit 302, the server control unit 302 It can also be done autonomously and automatically.

  As described above, in the communication system according to the present embodiment, a signal indicating that the operation is normal in the normal state is transmitted at low speed. It can help the user early and guide the user to get out of the emergency. In an emergency, imaging information indicating a user's situation is output to the center device using a high-speed communication line, so that support can be provided based on imaging information with good video quality early after the occurrence of an emergency. The imaging information sent to the center device is not only the video information after the emergency occurrence, but also the pre-event video, so-called pre-occurrence time, so the center side can check the situation of the user more accurately, Appropriate support becomes possible. In particular, according to the support operator of the monitoring center, it is possible to provide more advanced and appropriate support utilizing the experience of the support operator from the displayed imaging signal. Moreover, since the priority of the imaging information from the communication terminal device of the user who has experienced an emergency is increased, the center device can reliably receive the emergency imaging information.

  In the present embodiment, it is assumed that an emergency notification signal is output to the transmission control unit 202 or the like when the user operates the emergency operation unit 208 when an emergency has occurred. The communication terminal device 200 may include a separate sensor for monitoring the user's situation, and the emergency notification signal may be output by detecting an emergency although the sensor is built in. As this sensor, for example, an acceleration sensor may be built in, and a sudden change amount generated in the communication terminal device 200 due to an impact or a drop may be detected, and an emergency notification signal may be automatically output.

  In the above description, the imaging information of the camera unit 206 is not transmitted in the normal state, but the communication terminal device 200 according to the present embodiment is not limited to this, and the user sets the communication terminal device 200 in the normal state. If set, for example, imaging information of about 5 frames per second may be transmitted at low speed, or imaging information with low accuracy and low image quality may be transmitted at low speed. In this way, even if it is a continuous transmission in the normal state, if it is performed at a low speed, it is possible to avoid excessive communication traffic at the normal time and burden on the server of the center device. . In addition, when an emergency state occurs, it can be promptly transmitted from the communication terminal device 200 to the server device 300. Furthermore, if imaging information of a predetermined quality can be transmitted to the center side even in the normal state, the operator of the monitoring center 350 can confirm the user's situation using the screen information from the communication terminal device 200. Accurately grasp and provide quick support. Thus, a user who has set transmission of image information even in a normal state can receive thicker support from the center apparatus side.

  In the present embodiment, the destination of the user is registered by the monitored registration unit 201 first when the user requests monitoring. However, the present invention is not limited to this, and the user changes the destination. Each time a new operation is performed, or a timer device may be built in the communication terminal device 200 and transmitted to the monitoring center 350 or the like every predetermined time, for example, 10 minutes. Similarly, the server device 300 communicates with the communication terminal device 200 every predetermined time, for example, 10 minutes, and acquires the setting contents of the monitored registration unit 201 and the imaging information of one frame of the camera unit 206, for example. Also good.
