Description

  The present invention relates to a communication relay device, a communication terminal, a communication system and a communication method, and a computer program.

  In recent years, portable terminals (also referred to as portable terminals and communication terminals) such as smartphones and notebook personal computers have become widespread. Since the portable terminal is also used at the destination, a mobile router may be used as a means for connecting to the Internet. Mobile routers are assumed to be used on the go, and some have a mode for reducing power consumption so that they can be used for a long time.

  If the user does not use the mobile router (communication relay device) to achieve both long-term use and convenience, the communication relay device will switch to a mode that reduces power consumption. The communication relay device is expected to return from the mode that suppresses power consumption.

  When the state (mode) of the communication relay device is linked to the user's operation on the mobile terminal (for example, notification that the communication relay device is activated from the application embedded in the mobile terminal), the communication relay from the mobile terminal Sending commands to the device may fail. In this case, if the state of the communication relay device does not change according to the command from the application, a mismatch occurs between the command (instruction) by the application of the mobile terminal and the actual state of the communication relay device. As described above, there are cases where the mobile terminal cannot correctly know the state of the communication relay device at that time point only by the operation information of the application executed by the mobile terminal.

  Conversely, even when the state of the communication relay device is changed by an operation in the communication relay device, if the correct information is not transmitted to the mobile terminal, only the information held by the application executed by the mobile terminal The state of the communication relay device at that time cannot be correctly known by the portable terminal.

  Here, as related technologies existing prior to the present application, there are, for example, the following patent documents.

  Patent Document 1 discloses a technique for providing consulting information indicating how to use a home appliance to the home appliance from a server device connected via a network.

  Patent Document 2 discloses a technique for appropriately setting a communication cycle in order to reduce power consumption of a portable information communication device as much as possible.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration of a communication system according to the first embodiment of the present invention.

  The communication system according to the present embodiment includes a communication terminal 100 and a communication relay device 200.

  The communication terminal 100 is a portable terminal such as a smartphone or a notebook personal computer.

  The communication terminal 100 includes a control unit 101, a first communication unit 102, a second communication unit 103, and a display unit 104.

  The display unit 104 can display a connection state between the communication terminal 100 and the communication relay device 200.

  The control unit 101 controls the state of the communication relay device 200. There are two types of states of the communication relay device 200 held by the control unit 101 in the present embodiment. The first state is a state in which the communication relay device 200 is activated and the communication terminal 100 and the communication relay device 200 are communicating (a state in which power consumption is high. Hereinafter, also referred to as “communication state”). Another state is a state in which the communication relay device 200 is in a power saving state and the communication terminal 100 and the communication relay device 200 are not communicating (a state in which power consumption is extremely low. Hereinafter, also referred to as “non-communication state”). It is.

  The communication relay device 200 is a portable communication relay device such as a mobile router.

  The communication relay device 200 includes a control unit 201, a first communication unit 202, a second communication unit 203, and a third communication unit 204.

  The control unit 201 controls the state of the communication relay device 200.

  The communication terminal 100 and the communication relay device 200 are communicably connected by the first communication unit 102 and the first communication unit 202, and the second communication unit 103 and the second communication unit 203.

  The first communication unit (102, 202) is a communication unit that has high communication speed but high power consumption. The first communication unit (102, 202) is, for example, a wireless LAN (Local Area Network).

  The second communication unit (103, 203) is a communication unit that has a low communication speed but low power consumption. The second communication unit (103, 203) is, for example, Bluetooth (registered trademark).

  The third communication unit 204 connects the communication relay device 200 to a communication means (communication line) different from the above-described two types of communication means such as the Internet. The third communication unit 204 is, for example, WiMAX (Worldwide Interoperability for Microwave Access).

  When the communication unit 100 detects the communication ID of the communication relay device 200 as a result of searching the operation state of the first communication unit 102, the control unit 101 of the communication terminal 100 determines that the communication relay device 200 is in the activated state. . The communication ID (identifier) is information that can identify the communication relay device 200 and represents a value unique to the communication relay device.

  However, if the user is set so that the communication ID of the first communication unit 202 of the communication relay device 200 cannot be detected from the outside in order to improve security, the communication ID of the communication relay device 200 is searched from the communication terminal 100. I can't find it. For example, if the wireless LAN SSID (Service Set Identifier) is set so that it cannot be detected from the outside using the stealth function, the wireless LAN SSID will not appear in the search result even if a search is performed. Therefore, depending on the setting of the communication relay device 200, the control unit 101 cannot determine whether the communication relay device 200 is in an activated state based on whether the communication ID of the communication relay device 200 is detected. .

  Therefore, in the present embodiment, the communication relay device 200 communicates with the communication terminal 100 using the second communication unit 203 instead of the first communication unit 202. The communication relay device 200 communicates with the communication terminal 100 using the communication ID 206 in the activated state and the communication ID 207 in the power saving state as the communication ID. In addition, the first communication unit of the communication relay device 200 communicates with the communication terminal 100 using the communication ID 205.

  The communication terminal 100 recognizes whether the communication relay device 200 is in the power saving state or in the activated state based on the value represented by the communication ID of the second communication unit 203 of the communication relay device 200. That is, the communication relay device 200 according to the present embodiment has two values as the communication ID, and uses these two values depending on the state of the communication relay device 200.

  The communication relay device 200 changes the communication ID of the second communication unit 203 from the communication ID 206 to the communication ID 207 when transitioning from the activated state to the power saving state. On the other hand, when transitioning from the power saving state to the activated state, the communication relay device 200 changes the communication ID of the second communication unit 203 from the communication ID 207 to the communication ID 206.

  The communication terminal 100 searches the second communication unit 103 in its own terminal, and acquires a communication ID currently used by the second communication unit 103. Based on the communication ID, the control unit 101 determines the state of the communication relay device 200. When the communication ID 206 is detected in the communication ID, the control unit 101 determines that the communication relay device 200 is activated. When the communication ID 207 is detected, the control unit 101 determines that the communication relay device 200 is in the power saving state. When neither the communication ID 206 nor the communication ID 207 is detected, the control unit 101 determines that the communication relay device 200 is not nearby or is not turned on.

When the control unit 101 of the communication terminal 100 determines that the communication relay device 200 is in the activated state, the communication terminal 100 and the communication relay device 200 are connected by the first communication unit (102, 202). In addition, the control unit 101 displays on the display unit 104 that the normal transition has been made, and notifies the communication state. When the control unit 101 of the communication terminal 100 determines that the communication relay device 200 is in the power saving state, the control unit 101 displays on the display unit 104 and notifies the display unit 104 of the normal transition, and transitions to the non-communication state.
((When the communication terminal 100 instructs the communication relay device 200 in the activated state to transition to the power saving state))
Next, a process in which the communication terminal 100 recognizes that the communication relay device 200 has transitioned from the activated state to the power saving state will be described.

  FIG. 2 is a flowchart showing processing in the control unit 101 of the communication terminal 100 when the communication relay device 200 according to the first embodiment of the present invention transitions from the activated state to the power saving state.

  First, it is assumed that the communication terminal 100 is in communication with the communication relay device 200 by the first communication unit 102. That is, the control unit 101 recognizes that its own device is in a communication state. The communication relay device 200 is in a state where the first communication unit 202 and the second communication unit 203 can communicate with the first communication unit 102 and the second communication unit 103, respectively. The third communication unit 204 makes the communication relay device 200 connectable to the Internet.

  The control unit 101 of the communication terminal 100 acquires information about the communication relay device 200 using the first communication unit 102 (step S110).

  When the information of the communication relay device 200 can be acquired (“Yes” in step S120), the control unit 101 uses the first communication unit 102 to request the communication relay device 200 to transition to the power saving state. (Step S130).

  Next, the control unit 101 sets “0” to a counter (here, “n”) (step S140). The counter is used to determine the upper limit value of the number of processing repetitions. Here, as an example, the upper limit value is assumed to be “3”.

  The control unit 101 of the communication terminal 100 searches the operation state of the second communication unit 103 and acquires the communication ID currently used by the second communication unit 103 (step S160). When the communication ID 207 that is the communication ID of the second communication unit 203 is found in the communication ID (“Yes” in step S170), the control unit 101 normally shifts the communication relay device 200 to the power saving state. Judge that Then, the control unit 101 notifies the user of the communication terminal 100 using the display unit 104 that the communication relay device 200 has entered the power saving state. When the communication relay device 200 enters the power saving state, the control unit 101 transitions to a non-communication state (step S180).

  When the communication ID 207 that is the communication ID of the second communication unit 203 cannot be found in the communication ID (“No” in step S170), the control unit 101 adds “1” to the counter (step S171). ). When the counter is smaller than “3” (“Yes” in step S150), the control unit 101 searches the operation state of the second communication unit 103 (step S160) and performs the above-described process again. When the counter is “3” or more (“No” in step S150), the control unit 101 determines that the communication relay device 200 has failed to transition to the power saving state (step S151).

  FIG. 3 is a flowchart showing processing in the control unit 201 of the communication relay device 200 when the communication relay device 200 according to the first embodiment of the present invention transitions from the activated state to the power saving state.

The control unit 201 of the communication relay device 200 uses the first communication unit 202 to receive a request for transition to the power saving state from the communication terminal 100 (step S210). The control unit 201 changes the communication ID of the second communication unit 203 to the communication ID 207 (step S220). Next, the control unit 201 puts the third communication unit 204 into a state where it cannot communicate (invalid) (step S230). The control unit 201 makes the first communication unit 202 unable to communicate (step S240). Thereafter, the control unit 201 places the communication relay device 200 in a power saving state.
((When the communication terminal instructs the communication relay device 200 in the power saving state to transition to the activated state))
Next, a process in which the communication terminal 100 recognizes that the communication relay device 200 has transitioned from the power saving state to the activated state will be described.

  FIG. 4 is a flowchart illustrating processing in the control unit 101 of the communication terminal 100 when the communication relay device 200 according to the first embodiment of the present invention transitions from the power saving state to the activated state.

  First, it is assumed that the communication relay device 200 is in a power saving state. That is, the first communication unit 202 and the third communication unit 204 are in a state where communication is not possible, and the second communication unit 203 has a communication ID 207 in a state where communication is possible. Further, the control unit 101 of the communication terminal 100 is in an uncommunication state.

  The control unit 101 of the communication terminal 100 searches the operation state of the second communication unit 103, and acquires the communication ID currently used by the second communication unit 103 (step S310).

  When the communication ID 207 that is the communication ID of the second communication unit 203 is found in the communication ID (“Yes” in step S320), the control unit 101 can issue an activation request to the communication relay device 200. (Step S330). The communication terminal 100 transmits an activation request to the communication relay device 200 using the second communication unit 103 (step S340).

  Next, the control unit 101 sets “0” to a counter (here, “n”) (step S350). The counter is used to determine the upper limit value of the number of processing repetitions. Here, as an example, the upper limit value is assumed to be “3”.

  The communication terminal 100 searches the operation state of the second communication unit 103, and acquires the communication ID currently used by the second communication unit 103 (step S370). When the communication ID 206 can be found by the search of the second communication unit 103 (“Yes” in step S380), the control unit 101 connects to the communication relay device 200 using the first communication unit 102 (step S390). When the connection is completed, the control unit 101 of the communication terminal 100 transitions to a communication state (step S400).

  When the communication ID 206 that is the communication ID of the second communication unit 203 cannot be found in the communication ID (“No” in step S380), the control unit 101 adds “1” to the counter (step S381). ). When the counter is smaller than “3” (“Yes” in step S360), the control unit 101 searches the operation state of the second communication unit 103 (step S380) and performs the above-described processing again. When the counter is “3” or more (“No” in step S360), the control unit 101 determines that the communication relay device 200 has failed to transition to the activated state (step S361).

  FIG. 5 is a flowchart showing processing in the control unit 201 of the communication relay device 200 when the communication relay device 200 according to the first embodiment of the present invention transitions from the power saving state to the activated state.

  The communication relay device 200 receives an activation request from the communication terminal 100 using the first communication unit 202 (step S410).

  The communication relay device 200 sets the third communication unit 204 in a communicable (valid) state (step S430), and sets the first communication unit 202 in a communicable state (step S440). Next, the control unit 201 changes the communication ID of the second communication unit 203 to the communication ID 206 (step S450).

  FIG. 6 is a flowchart showing processing in the control unit 201 of the communication relay device 200 when the communication relay device 200 according to the first embodiment of the present invention transitions from the power saving state to the activated state.

  FIG. 6 is obtained by adding step S560 and subsequent steps to the flowchart of FIG. Steps S510 to S550 in FIG. 6 are the same as steps S410 to S450 in FIG.

  The communication relay device 200 confirms the connection with the communication terminal 100 (step S560). If the communication relay device 200 is connected to the communication terminal 100 (“Yes” in step S570), the communication relay device 200 invalidates the second communication unit 203 (step S580).

  Even if the second communication unit 203 is disabled, there is no problem because the communication relay device 200 can communicate with the communication terminal 100 using the first communication unit 202.

  As described above, according to the first embodiment, when the state of the communication relay device 200 is changed from the control unit 101 of the communication terminal 100, the state that the state of the communication relay device 200 has changed normally is early. There is an effect that it can be grasped.

  The reason is that in the communication system according to the present embodiment, the second communication unit 203 of the communication relay device 200 has different communication IDs in the activated state and the power saving state. The communication ID 206 indicating the activation state and the communication ID 207 indicating the power saving state are checked. Thereby, according to the present embodiment, the communication terminal 100 can grasp the state of the communication relay device 200. Thus, if the communication terminal 100 uses the value represented by the communication ID of the second communication unit 203 to determine the state of the communication relay device 200, the value represented by the communication ID of the first communication unit 202. However, even if it cannot be detected from the outside by the stealth function, the communication terminal 100 can grasp the state of the communication relay device 200.

  Furthermore, the communication relay device 200 transitions from the power saving state to the activated state, and after confirming the connection with the communication terminal 100 after the transition, the second communication unit 203 is disabled to allow further power saving. Can do.

  In the first embodiment described above, the function of the control unit 101 shown in FIG. 1 can also be achieved by executing a computer program on a computer (processor) (not shown) included in the communication terminal 100. The function of the control unit 201 shown in FIG. 1 can also be achieved by executing a computer program on a computer (processor) (not shown) included in the communication relay device 200.

<Second Embodiment>
Next, a second embodiment based on the communication system according to the first embodiment described above will be described.

  FIG. 7 is a block diagram showing a configuration of a communication system according to the second embodiment of the present invention.

The communication system according to the present embodiment is obtained by adding an operation unit 208 to the configuration described in the second embodiment. That is, the communication relay device 200 includes an operation control system 201, a first communication unit 202, a second communication unit 203, a third communication unit 204, and an operation unit 208. The communication relay device 200 can change the state by the operation unit 208.
((When the operation unit 208 instructs the communication relay device 200 in the power saving state to transition to the activated state))
FIG. 8 is a flowchart showing processing in the control unit 101 of the communication terminal 100 when the communication relay device 200 according to the second embodiment of the present invention transitions from the power saving state to the activated state by the operation unit 208.

  First, it is assumed that the communication relay device 200 is in a power saving state. That is, the first communication unit 202 and the third communication unit 204 are in a state where communication is not possible, and the second communication unit 202 has a communication ID 207 in a state where communication with the terminal 100 is possible. Further, the control unit 101 of the communication terminal 100 is in an uncommunication state.

  The control unit 101 sets “0” to a counter (here, “n”) (step S610). The counter is used to determine the upper limit value of the number of processing repetitions. Here, as an example, the upper limit value is assumed to be “3”.

  The control unit 101 of the communication terminal 100 searches the operation state of the second communication unit 103 and acquires the communication ID currently used by the second communication unit 103 (step S630).

  When the communication ID 207 that is the communication ID of the second communication unit 203 is found in the communication ID (“Yes” in step S640), the control unit 101 determines that the communication relay device 200 is in the power saving state. (Step S650).

  When the communication ID 207 cannot be found in the communication ID (“No” in step S640), the control unit 101 searches for the communication ID 206. When the communication ID 206 is found (“Yes” in step S641), the control unit 101 transitions to a communication state (step S651).

  When the communication ID 206 and the communication ID 207 cannot be found together (“No” in step S641), the control unit 101 adds “1” to the counter (step S642). When the counter is smaller than “3” (“Yes” in step S620), the control unit 101 searches the operation state of the second communication unit 103 (step S630), and performs the above-described process again. If the counter is “3” or more (“No” in step S620), the control unit 101 ends the process.

  As described above, in the second embodiment, even when the operation unit 208 of the communication relay device 200 changes the state of the communication relay device 200, the communication terminal 100 changes the state of the communication relay device 200. There is an effect that it can be grasped early.

  The reason is that in the communication system according to the present embodiment, the second communication unit 203 of the communication relay device 200 has different communication IDs in the activated state and the power saving state. This is because the state of the communication relay device 200 can be grasped by checking which communication ID 206 indicating the activation state or communication ID 207 indicating the power saving state is used. Thus, if the communication terminal 100 uses the value represented by the communication ID of the second communication unit 203 to determine the state of the communication relay device 200, the value represented by the communication ID of the first communication unit 202. However, even if it cannot be detected from the outside by the stealth function, the communication terminal 100 can grasp the state of the communication relay device 200.
