  FIG. 4 is a sequence diagram showing a flow of processing for pre-registering terminal remote control information from the maintenance terminal 11 to the registration management system 101.

  Referring to FIG. 4, first, a control information registration request is transmitted from maintenance terminal 11 to registration management system 101 (step S101). This control information registration request includes a terminal ID, which is terminal identification information of the terminal 301 to be registered, and a remote control code indicating control content.

  The registration management system 101 returns a control information registration response in response to the control information registration request received from the maintenance terminal 11 (step S102). This control information registration response includes OK (registration is possible) or NG (registration is not possible) information as a registration result.

  If registration is possible (OK), the registration management system 101 stores the terminal ID and remote control code in the terminal remote control information storage unit 110 as terminal remote control information (step S103).

  With the above processing procedure, the maintenance terminal 11 can register the terminal remote control information for the terminal 301 in the terminal remote control information storage unit 110.

  FIG. 5 is a sequence diagram showing the flow of the first remote control process in the terminal remote control device according to the present invention. Hereinafter, the processing flow will be described with reference to FIG.

  When a data transmission request is generated in the terminal 301 in the sleep period (sleep state) (step S201), the terminal 301 transitions to the wakeup period (active state). Then, a terminal authentication request is transmitted from the terminal 301 to the relay node 201 (step S202). This terminal authentication request includes a terminal ID (terminal identification information) and a terminal authentication key (authentication data) for authenticating the legitimacy of the terminal.

  The relay node 201 transmits the terminal authentication request received from the terminal 301 to the registration management system 101 (step S203). The registration management system 101 authenticates the terminal 301 based on the terminal ID and the terminal authentication key included in the terminal authentication request received from the relay node 201, and transmits a terminal authentication response to the relay node 201 (step S204). . This terminal authentication response includes information on the terminal ID, the authentication result (OK / NG), and the remote control code.

  The relay node 201 transmits a terminal authentication response to the terminal 301 based on the terminal authentication response received from the registration management system 101 (step S205). The terminal authentication response transmitted to the terminal 301 includes the terminal ID and authentication result (OK / NG) information.

  After receiving the terminal authentication response from the relay node 201 and obtaining authentication, the terminal 301 transmits a communication acceptance request to the relay node 201 (step S206). This communication acceptance request includes information on the terminal ID.

  When receiving the communication acceptance request from the terminal 301, the relay node 201 determines whether or not the terminal 301 needs to be remotely controlled based on the terminal ID of the terminal 301 (step S207). In this determination, when a remote control code for the terminal 301 is stored, the difference between the terminal 301 and the remote control code acquired at the previous authentication is compared to determine the necessity of control processing.

  When the relay node 201 determines that remote control of the terminal 301 is necessary (step S207: YES), a terminal control request is transmitted to the terminal 301 (step S208). This terminal control request includes information on the terminal ID and the remote control code.

  The terminal 301 performs control processing based on the remote control code included in the terminal control request received from the relay node 201 (step S209). In this control process, the necessity for the remote control process is determined by comparing the difference with the remote control code acquired at the time of previous authentication, and the remote control process is performed when it is determined that it is necessary.

  After executing the control process based on the remote control code, the terminal 301 transmits a terminal control response to the relay node 201 (step S210). This terminal control response includes the terminal ID and the remote control result (OK / NG).

  When receiving the terminal control response from the terminal 301, the relay node 201 transmits a communication acceptance response to the terminal 301 (step S211). This communication reception response includes information on the terminal ID and the communication reception result (OK / NG).

  On the other hand, when it is determined that there is no need for remote control in the determination of the necessity of remote control of the terminal in step S207 (step S207: NO), the process proceeds to step S211 and the communication acceptance response is sent to the terminal. 301 is transmitted.

Thereafter, the terminal 301 transmits data to the relay node 201 (step S 21 2). This transmission data includes terminal ID information and data to be communicated. After data transmission, the terminal 301 transitions to a sleep period (rest state).

  The relay node 201 transmits the transmission data received from the terminal 301 to the Internet GW 31 (step S213). The Internet GW 31 transmits the transmission data received from the relay node 201 to the PC 41 (Step S214).

With the remote control sequence described above, the terminal 301 does not always have to be able to wait for an incoming call, and remote control of the terminal 301 that is activated only when data communication is necessary is possible.
Further, on the registration management system 101 side, remote control can be performed even if the position of the terminal 301 is not always managed. For this reason, it is possible to save the wireless bandwidth associated with the remote control, which is effective for a wireless system having a narrow bandwidth (shared by tens of thousands of terminals).

  FIG. 6 is a sequence showing a flow of second remote control processing in the terminal remote control system according to the present invention.

  The sequence showing the flow of the second remote control process shown in FIG. 6 is different from the sequence showing the flow of the first remote control process shown in FIG. 5 in the steps enclosed by the broken line block in FIG. S207A and step S207B are newly added, and the other processing steps are the same as the sequence showing the flow of the first remote control processing shown in FIG. For this reason, the same processing steps are denoted by the same reference numerals, overlapping description is omitted, and only newly added steps will be described.

  When the necessity for remote control of the terminal in step S207 of FIG. 6 is determined (step S207: YES), the relay node 201 sends a request for continuous reception extension to the terminal 301. Is transmitted (step S207A). The continuous reception extension request includes information on the terminal ID and the continuous reception end timer. When the terminal remote control information is transmitted as a control message to the terminal 301 by this continuous reception extension request, the continuous reception is terminated in advance. After instructing the extension of the timer (the sleep timer that determines the time from when the terminal 301 once wakes up to sleep), the remote control setting information is sent. In this continuous reception extension request, it is also possible to control the terminal 301 to stop the continuous reception end timer.

  In the terminal 301, the continuous reception end timer is extended based on the continuous reception extension request received from the relay node 201 (step S207B).

  With the above processing, the extension of the continuous reception end timer time of the terminal 301 can be controlled, but this extended time may be determined in advance according to the contents of the remote control processing in step S207B. When instructing to stop the sleep in step S207A, the terminal 301 sleeps after the remote control process (step S209) is completed.

  The embodiment of the present invention has been described above. However, in the description of the above embodiment, when the terminal is in a sleep state (sleep), the terminal does not receive terminal remote control information from the terminal remote control device. Although the terminal remote control device has been described as being incapable of remote control of the terminal, the present invention is not limited to this.

  For example, even if the terminal is in a place where radio waves do not reach from the terminal remote control device due to shielding, etc., and the terminal remote control information from the terminal remote control device does not reach the terminal, the terminal transitions to the dormant state As in the case where the terminal is remote, the terminal remote control device may not be able to remotely control the terminal.

  As described above, even when the terminal cannot be remotely controlled from the terminal remote control device because the radio waves from the terminal remote control device do not reach the terminal, the terminal remote control device according to the present embodiment allows the terminal remote control device to The terminal remote control information is stored, the terminal remote control device receives the terminal identification information from the terminal, and the radio waves of the terminal remote control device reach the terminal. Is transmitted to the terminal by the terminal remote control device, it becomes possible for the terminal remote control device to remotely control the terminal even for a terminal for which radio waves from the terminal remote control device have not arrived.

  Further, the terminal remote control device according to the present embodiment is not limited to a terminal as a target terminal, and can be similarly applied to a wired terminal in which the operation state of the terminal transitions to a dormant state.

  Further, each processing unit in the registration management system 101 and the relay node 201 shown in FIG. 2 may be realized by dedicated hardware, or each processing unit in the registration management system 101 and the relay node 201. The program for realizing the above function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to realize the function. . Here, the “computer system” includes an OS and hardware such as peripheral devices.

  In addition, it is assumed that an input device, a display device, and the like (none of them are displayed) are connected to the registration management system 101 and the relay node 201 as peripheral devices. Here, the input device refers to an input device such as a keyboard and a mouse. The display device refers to a CRT (Cathode Ray Tube), a liquid crystal display device, or the like.

Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
