  When performing remote operation using the above method, it is necessary to receive an SMS from a service provider at an information terminal. In order to receive the SMS by the information terminal, it is necessary to secure a storage area of a specific size for performing processing related to the reception of the SMS. However, in an information terminal such as a smartphone or a tablet terminal, an operation of downloading data from the network is frequently performed by a user operation, and therefore SMS cannot be received and remotely operated by the information terminal without the user's knowledge. It can be a situation.

  The present invention has been made in view of the above, and an object thereof is to provide a terminal control system, a terminal control server, an information terminal, and a terminal control method capable of reliably performing remote operation of an information terminal.

Remote operation means for transmitting an instructing remote operation start signal.

  An information terminal according to the present invention is an information terminal included in a terminal control system including a terminal control server and an information terminal, and is transmitted from the terminal control server and instructs the start of remote processing in the information terminal. A memory in which a remote operation memory area for receiving a remote operation start signal is secured in advance and a preparation signal for instructing execution of a preparation process for starting a remote process transmitted from the terminal control server are received. Together with a preparation communication means for transmitting a response signal to the preparation signal to the terminal control server, and upon receipt of the preparation signal by the preparation communication means, the remote operation memory area included in the memory is released. Memory area releasing means, and the remote operation start signal from the terminal control server after processing in the memory area releasing means Receiving, characterized in that it comprises a remote processing unit for starting the remote processing.

  In the terminal control system described above, the memory area for remote operation is secured in the memory in advance in the information terminal, so that the memory area necessary for receiving the remote operation start signal is lost due to data download by the user. Is prevented. Then, by transmitting a preparation signal from the terminal control server to the information terminal before transmitting the remote operation start signal, the remote operation memory area secured in the memory of the information terminal is released. Therefore, before the remote control start signal is received at the information terminal, the memory capacity can be increased by the size of the remote control memory area. Therefore, the remote control start signal can be reliably received using this open area. can do.

  As described above, when the memory area releasing means determines whether or not it is necessary to open the memory area for remote operation based on the free capacity of the memory, the remote area can be remotely controlled even though the free capacity of the memory is sufficiently secured. Since the operation memory area can be prevented from being released, the amount of processing in the information terminal can be reduced.

Hereinafter, returning to FIG. 1, the function of each device will be described in detail.

  The remote service providing device 10 included in the terminal control system 1 is a device that provides a service for remotely operating the information terminal 30 to a user. The services provided by the remote service providing apparatus 10 include, for example, a location information providing service that provides location information of the information terminal 30, a terminal lock service that switches the information terminal 30 from a normal use state to a locked state, and the like. It is done. That is, in the terminal control system 1, examples of processing executed on the information terminal 30 by remote operation include acquisition and provision of position information and switching to a locked state.

  In the case of the location information providing service, the remote service providing device 10 includes, for example, an LCS (Location Service) Client that acquires location information of the information terminal 30 and provides a user interface with a location information searcher. In the case of a terminal lock service, the remote service providing apparatus 10 includes, for example, a system provided for managing an information terminal related to a user.

  The remote service providing apparatus 10 identifies the information terminal 30 that wants to execute the remote processing and obtain the result, and the content of the processing that the information terminal 30 wants to execute (acquisition of location information, terminal lock, etc.) The remote processing execution instruction is transmitted to the terminal control server 20 and the execution result is acquired from the terminal control server 20.

  The terminal control server 20 is a device having a function of causing the information terminal 30 to execute a predetermined process by remote operation based on an instruction from the remote service providing device 10.

  The terminal control server 20 includes a terminal communication unit 21 (preparation processing unit, remote operation unit), a remote service processing unit 22, and a terminal information storage unit 23 (preparation processing unit, remote operation unit). The terminal communication unit 21 has a function of performing communication with the information terminal 30 based on an instruction from the remote service providing apparatus 10. The remote service processing unit 22 has a function of communicating with the remote service providing apparatus 10, and processes such as processing the information acquired from the information terminal 30 to provide to the remote service providing apparatus 10. It is done together. The terminal information storage unit 23 has a function of storing information necessary for communicating with the information terminal 30 based on an instruction from the remote service providing apparatus 10. Specifically, in-service information of the information terminal 30, information specifying the model of the information terminal 30, and the like are associated with information (for example, a telephone number) specifying the information terminal 30. Further, an authentication key or the like for performing a specific process (for example, terminal lock) on the information terminal 30 may be stored in association with the information terminal 30.

  The terminal communication unit 21 of the terminal control server 20 performs two-stage communication with the information terminal 30 based on an instruction from the remote service providing apparatus 10. The first-stage communication is communication for causing the information terminal 30 to execute a preparation process in order to start remote processing in the information terminal 30. Communication for executing this preparation processing includes telephone call as a preparation signal to the information terminal 30 and reception of a preparation completion response as a response signal from the information terminal 30. The communication at the second stage is communication for executing remote processing in the information terminal 30 that has performed the preparation processing. The communication for executing the remote processing includes the transmission of SMS (Short Message Service) as a remote operation start signal to the information terminal 30 and the execution result of the remote processing based on the remote operation start signal from the information terminal 30. Reception is also included. Is mentioned. This point will be described later. When the terminal communication unit 21 communicates with the information terminal 30, communication is performed using information related to the information terminal 30 stored in the terminal information storage unit 23.

  The apparatus which comprises the terminal control server 20 is changed according to the content of the process performed in the information terminal 30. FIG. The terminal control server 20 may be realized by a single device, but in many cases, the function as the terminal control server 20 is exhibited by a plurality of devices operating in conjunction with each other. When the service provided by the remote service providing device 10 is a location information providing service, the terminal control server 20 includes, for example, an SLP (SUPL Location Platform) / GMLC (Gateway Mobile Location) functioning as a platform for the location information providing service. Center), an HSS (Home Subscriber Server) for managing subscriber information, an SMS center for transmitting SMS to the information terminal 30, and the like. When the service provided by the remote service providing apparatus 10 is a terminal lock service, the terminal control server 20 includes, for example, an HSS (Home Subscriber Server) that manages subscriber information and information on the information terminal 30, a remote DME (Device Management Equipment) that changes settings of the information terminal 30 by operation, a database that manages telephone numbers and the like associated with the information terminal 30, and an SMS for transmitting SMS to the information terminal 30 Centers etc. are included.

  The information terminal 30 includes a communication unit 31 (preparation communication unit, memory area release unit, remote processing unit) that performs communication with the terminal control server 20, and a control unit 32 (memory area release) that performs control related to remote processing in the information terminal 30. Means, remote processing means), and a memory 33 for executing the remote processing. In the memory 33, a remote operation memory area 35 as a capacity for performing the remote operation is secured in advance. The remote operation memory area 35 is secured by storing some substitute data (image data or the like generated on the information terminal 30 side) in the memory 33 during normal use.

  The communication unit 31 has a function of performing a series of communications with the terminal control server 20. In communication performed with the terminal control server 20, as a first-stage communication, an incoming call as a preparation signal from the terminal control server 20 and transmission of a preparation completion response as a response signal to the terminal control server 20 are included. included. In the second stage communication, SMS (Short Message Service) as a remote operation start signal instructing execution of remote processing from the terminal control server 20 and remote processing based on the remote operation start signal are performed. Transmission of the execution result to the terminal control server 20 is included. Information received by the communication unit 31 is sent to the control unit 32.

  The control unit 32 has a function of controlling processing related to remote operation based on an instruction from the terminal control server 20. When the communication unit 31 receives a preparation signal from the terminal control server 20, the communication unit 31 opens the remote operation memory area 35 in the memory 33 and instructs the communication unit 31 to transmit a preparation completion response. When the communication unit 31 receives a remote operation start signal, the communication unit 31 transmits a notification of the result to the communication unit 31 after executing the process specified in the remote operation start signal. If necessary, the remote operation memory area 35 may be secured again after a series of remote operation processes are completed.

  The memory 33 is used as an area for storing information when communication by the communication unit 31 and execution of processing by the control unit 32 are performed. As described above, the memory 33 for the remote operation is secured in advance in the memory 33, and the remote operation memory area 35 is opened under the control of the control unit 32.

  Next, the terminal control method by the terminal control system 1 will be described with reference to the sequence diagram shown in FIG.

  First, the remote service providing apparatus 10 transmits to the terminal control server 20 a remote process execution instruction for instructing execution of a remote operation related to the information terminal 30 together with information for specifying the information terminal 30 (S01). When a remote processing execution instruction is received by the remote service processing unit 22 of the terminal control server 20, information stored in the terminal information storage unit 23 (telephone number, location information, etc.) by the terminal communication unit 21 of the terminal control server 20 ), A preparation signal for performing a remote operation is transmitted to the information terminal 30 (S02: preparation processing step / preparation communication step). The type of the preparation signal is not particularly limited, but is preferably a signal that uses a small amount of the memory 33 of the information terminal 30 or a signal that does not use the memory 33. For example, a telephone call to the information terminal 30 can be used. . Note that, when the configuration is such that a telephone call to the information terminal 30 is used as the preparation signal, it is necessary to distinguish from a normal incoming call from another terminal on the information terminal 30 side. As a method for distinguishing the preparation signal from the information terminal 30, for example, a telephone number when making a call to the information terminal 30 as a preparation signal is registered in the information terminal 30 in advance, and the number registered in the information terminal 30 is registered. When there is a call from, the call can be recognized as a preparation signal.

  In the information terminal 30, when the preparation signal is received by the communication unit 31, the control unit 32 releases the remote operation memory area 35 of the memory 33 (S03: memory area release step). The remote operation memory area 35 may be released by activating an application for releasing the memory area and executing a process related to the release. As a specific method for releasing the remote operation memory area 35, when the remote operation memory area 35 is occupied by alternative data or the like in a normal time when a preparation signal is not received, this alternative data is deleted. And increasing the free space. Thereafter, in response to an instruction from the control unit 32, a preparation completion response is transmitted from the communication unit 31 to the terminal control server 20 (S04: preparation communication step). The preparation completion response may be performed simultaneously with the release of the remote operation memory area 35 (S03), and the release of the remote operation memory area 35 is completed by the reception of the remote operation processing signal at the subsequent stage. That's fine.

  Further, when the preparation signal is received by the communication unit 31, it may be determined whether or not the remote control memory area 35 of the memory 33 is opened by the control unit 32 (S03). For example, even if the remote operation memory area 35 is not released, the usable area (free space) in the memory 33 has a sufficient margin for processing after receiving the remote operation processing signal in the subsequent stage (remote operation is performed). If it is equal to or greater than a predetermined value set as necessary for implementation), the subsequent process can be executed without releasing the remote control memory area 35. Therefore, the control unit 32 determines whether or not the remote operation memory area 35 needs to be opened based on the free capacity of the memory 33. If the free capacity of the memory 33 is smaller than a predetermined value, the remote operation memory area 35 is determined. Can be prevented from opening the remote operation memory area 35 even though the free space of the memory 33 is sufficient, reducing the processing that is not essential in the information terminal 30. it can. It should be noted that even when the control unit 32 determines that it is not necessary to open the remote operation memory area 35 before releasing the remote operation memory area 35 of the memory 33 (S03), Accordingly, a preparation completion response is transmitted from the communication unit 31 to the terminal control server 20 (S04: preparation communication step).

  After receiving the preparation completion response from the information terminal 30, the terminal communication unit 21 of the terminal control server 20 transmits a remote operation start signal to the information terminal 30 that has transmitted the preparation completion response (S05: remote instruction step). . This remote operation start signal is transmitted as SMS from the terminal control server 20 to the information terminal 30. Also at this time, information (telephone number, location information, etc.) stored in the terminal information storage unit 23 is used as necessary. The communication unit 31 of the information terminal 30 receives and stores the SMS after the processing in the previous stage (S03), and executes the predetermined processing instructed by the SMS in the control unit 32 (S06: remote processing step). At this time, all or part of the remote control memory area 35 opened in the previous stage (S03) may be used. Further, an area different from the remote operation memory area 35 in the memory 33 may be used. Further, when a signal is transmitted a plurality of times as a remote operation start signal, the process related to the first signal uses the remote operation memory area 35, and the process related to the second and subsequent signals is performed as the remote operation memory area 35. Can be configured to use different areas. Note that the processing executed with the reception of the remote operation start signal as an opportunity includes acquisition of position information, locking of the information terminal 30, and the like. When executing the process instructed by the SMS, the information terminal 30 may communicate with other devices as necessary.

  Thereafter, the result of the process executed by the information terminal 30 instructed by the SMS is transmitted as a process result notification from the communication unit 31 of the information terminal 30 to the terminal control server 20 (S07). The processing result included in the processing result notification includes, for example, the position information of the own terminal acquired by the information terminal 30 in the case of the position information providing service, and the own terminal is in the locked state in the case of the terminal lock service. The information indicating that the change has been made. When the terminal communication unit 21 of the terminal control server 20 receives the processing result notification from the information terminal 30, the remote service processing unit 22 transmits a remote processing result notification to the remote service providing apparatus 10 as a response to the remote processing execution instruction. (S08).

  Note that the remote operation memory area 35 may be re-reserved as necessary before or after the notification of the processing result from the information terminal 30 to the terminal control server 20 (S07) (S09). Re-reserving of the remote operation memory area 35 is necessary when there is a possibility that the remote operation may be performed again. For example, provision of position information of the information terminal 30 by the position information providing service may be performed a plurality of times by remote operation before the user operates the information terminal 30. Therefore, after a series of processing related to acquisition of position information is executed, a new remote operation memory area 35 is secured for the next remote operation using the memory area used for the processing. As a result, the second and subsequent remote operations can be performed smoothly.

  Regarding re-reserving of the remote operation memory area 35, the information terminal 30 may be instructed to the information terminal 30 by SMS transmitted as a remote operation start signal, or a series of processing related to the remote operation may be performed. The re-allocation may be performed without fail, including the re-allocation of the remote operation memory area 35 for the next time. As described above, when the remote operation memory area 35 is re-secured, the second and subsequent remote operations can be smoothly performed by the same process as the first. When the control unit 32 is configured to determine whether the remote operation memory area 35 needs to be opened, the control unit 32 does not need to open the remote operation memory area 35 before the first remote operation. If it is determined that there is, it is conceivable that the first remote operation ends without the remote operation memory area 35 being opened. In this case, since the remote operation memory area 35 for the second and subsequent remote operations has already been secured, the second and later remote operations can be performed without re-reserving. Therefore, a configuration may be further provided in which it is determined whether or not it is necessary to reallocate the remote operation memory area 35 based on whether or not the remote operation memory area 35 for the second and subsequent remote operations is secured. The terminal control process related to the remote operation is thus completed.

  The effect by the terminal control method by the terminal control system 1 which concerns on this embodiment is demonstrated. When the remote control of the information terminal 30 is performed by the terminal control system 1 described above, as described above, based on the remote control instruction from the remote service providing device 10, the terminal control server 20 and the information terminal 30 are largely operated. Two-stage communication is performed separately. The first-stage communication is communication for causing the information terminal 30 to execute a preparation process in order to start remote processing in the information terminal 30. The communication at the second stage is communication for executing remote processing in the information terminal 30 that has performed the preparation processing.

  Among these, the communication at the second stage, that is, the communication for executing remote processing in the information terminal 30 is communication standardized by OMA (Open Mobile Alliance) or the like, and S05 to S07 in FIG. The process shown in Specifically, it includes transmitting an SMS (Short Message Service) instructing execution of a specific process to the information terminal 30 as a remote operation start signal instructing the start of remote processing in the information terminal 30. The information terminal 30 executes processing designated by the SMS in response to the reception of the SMS. The process executed in the information terminal 30 triggered by the reception of the SMS is, for example, an information terminal such as activation of an application for performing a specific process, acquisition of position information using the activated application, or terminal lock Or at least a part of the application termination. All of these processes are performed in response to the reception of SMS, which is a remote operation start signal from the terminal control server 20, in the information terminal 30.

  Here, in order to receive the SMS at the information terminal 30, it is necessary to secure a memory area of a predetermined size (for example, 1 MB) in the memory 33 due to restrictions on the OS (Operating System) side of the information terminal 30. There is. In the conventional method of using the information terminal 30, it is considered that the memory 33 is not used until the memory area necessary for receiving the SMS is lost. It was not supposed. However, in recent usage methods of the information terminal 30, since the user has increased the chance of downloading data via the network, the memory area for receiving the SMS without the user's knowledge is lost. An event using the memory 33 may occur. In this case, since the information terminal 30 cannot receive the SMS as a remote operation start signal that triggers the information terminal 30 to execute the process by remote operation, the information terminal 30 can execute a desired process. It becomes difficult.

  As a method for solving the above problem, for example, it is conceivable that the remote operation start signal is a signal having a smaller capacity different from that of SMS. However, as described above, the signal used in the second-stage communication (S05 to S07) is a signal standardized by OMA or the like, and is difficult to change in the application on the information terminal 30 side. In addition, in order to perform remote operation of the information terminal 30 by adopting a signal different from the standardized signal (SMS), it is necessary to greatly change the specifications of the information terminal 30. From a point of view, it is not realistic.

  On the other hand, in the terminal control system 1 according to the present embodiment, in the information terminal 30, the remote operation memory area 35 is secured in the memory 33 in advance, so that the SMS is received by the user downloading the data or the like. A configuration for preventing the memory area to be lost from being lost. And in the terminal control system 1 which concerns on this embodiment, before transmitting SMS as a remote operation start signal, the memory 33 of the information terminal 30 is transmitted by transmitting a preparation signal from the terminal control server 20 to the information terminal 30. A series of first-stage communications (S02 to S04) is performed in which the remote operation memory area 35 secured in step S1 is released and the terminal control server 20 responds. Therefore, before the remote control start signal is received at the information terminal 30, the capacity of the memory 33 can be increased by the size of the remote control memory area 35. Therefore, SMS can be reliably received using this open area. can do. By adopting the above configuration, the remote operation at the information terminal 30 can be reliably executed without changing the second-stage communication (S05 to S07) standardized by OMA or the like. become.

  Further, in a normal state, the remote operation memory area 35 is secured in the memory 33 by alternative data or the like, and the remote operation memory area 35 is opened based on the preparation signal. Since it is possible to prevent a third party from operating the free space in the memory 33 of the information terminal 30 to be small, the remote operation of the information terminal 30 can be more reliably executed. Specifically, when the user of the information terminal 30 loses the information terminal 30, the user of the information terminal 30 tries to lock the information terminal 30 or transmit position information from the information terminal 30 by remote operation. Conceivable. However, when a malicious third party picks up the information terminal 30, there is a possibility that the remote operation of the information terminal 30 may be hindered by operating the information terminal 30 to store data so as to occupy the memory 33. is there. On the other hand, by providing the configuration for opening the remote operation memory area 35 based on the preparation signal as described above, the remote operation on the information terminal 30 can be reliably executed, and the malicious third It is possible to prevent a remote operation from being disturbed by a person.

  In addition, the terminal control system 1 according to the present embodiment has a configuration in which the remote operation memory area 35 is secured again in the memory 33 after the remote processing is completed, so that the first and subsequent remote operations are also performed. Therefore, the convenience relating to the remote operation of the information terminal 30 can be enhanced.

  Further, in the terminal control system 1 according to the present embodiment, it is determined whether or not the remote operation memory area 35 needs to be opened based on the free capacity of the memory 33, and when the free capacity of the memory 33 is smaller than a predetermined value. When the configuration for opening the remote operation memory area 35 is adopted, it is possible to prevent the remote operation memory area 35 from being opened even though the free space of the memory 33 is sufficient. The amount can be reduced.

  Although the preferred embodiments of the present invention have been described above, the terminal control system 1 according to the present invention can be variously modified.

  For example, the functions related to the remote service providing apparatus 10 and the terminal control server 20 shown in the terminal control system 1 may be all included in one apparatus, or each function is distributed to different apparatuses. It may be a configuration.

  Moreover, in the said embodiment, although it was set as the structure which transmits a preparation signal and a remote operation start signal with respect to the information terminal 30 based on the information stored in the terminal information storage part 23 provided in the terminal control server 20, The information stored in the information storage unit 23 may be obtained from another device (for example, the remote service providing device 10) and may communicate with the information terminal 30.
