Description

  The present invention relates to a remote control transmitter and a remote control receiver, and more particularly to a remote control transmitter and a remote control receiver that perform transmission or reception using radio.

  Conventionally, remote controllers that use infrared (IR) are widely used. Recently, a “remote control using radio waves” that takes advantage of non-directionality has also appeared.

  For example, Patent Document 1 incorporates Bluetooth (registered trademark) in order to compensate for the disadvantage of the conventional infrared remote control that the remote control must be directed to the operation target device, so that the remote control can be operated without worrying about the orientation. Is proposing a remote control.

  Patent Document 2 proposes a remote controller with low power consumption, which includes a low power consumption unit (infrared, Bluetooth, etc.) and a high-speed communication unit (IEEE 802.11, etc.) in the radio unit.

In Bluetooth, “pairing”, which is an operation for linking devices, is performed to prevent an operation other than the original user from being hijacked. There is a detailed description of Bluetooth in Non-Patent Document 1 and the like. Non-Patent Document 2 describes Secure Simple Pairing, which is a technique that makes Bluetooth pairing easier than in the past.

  According to the above configuration, the first remote control transmitter transmits a signal for turning on the power of the remote control receiver to be a communication partner by the transmitter-side infrared transmission unit. After transmitting a signal for turning off the remote control receiver, if the amount of power supplied to the transmitter-side radio wave transmitting / receiving unit is increased, the signal for turning off the remote control receiver is transmitted. There is no problem even if the power supply amount supplied to the transmitter-side radio wave transmission / reception unit is reduced, and the power consumption in the first remote control transmitter can be reduced by reducing the power supply amount.

  In addition, a first remote control receiver according to the present invention is a remote control receiver that communicates with a remote control transmitter, the receiver side infrared receiving unit that receives signals from the remote control transmitter via infrared rays, and the remote control A receiver-side radio transmission / reception unit that transmits / receives signals to / from the transmitter, a receiver-side infrared reception unit, a receiver-side power supply unit that supplies power to the receiver-side radio transmission / reception unit, and the remote control reception The receiver side that increases the power supply amount from the receiver-side power supply unit to the receiver-side radio wave transmission / reception unit after the receiver-side infrared receiving unit receives a signal for turning on the power of the receiver After the receiver-side radio wave transmitter / receiver or the receiver-side infrared receiver receives a signal for turning off the power-on control means and the remote control receiver, the receiver-side power supply unit It is characterized in that it comprises a receiver-side power-off control means for reducing the power supply to the receiver radio transceiver.

  Here, in order to make the explanation easier to understand, the external appearance of the remote control transmitter and the remote control receiver will be described with reference to the drawings before the operation of the remote control transmitter 100 and the remote control receiver 200 is described.

  FIG. 10 is a schematic diagram showing the external appearances of a remote control transmitter 1000 which is an example of a remote control transmitter according to the present invention and a remote control receiver 1010 which is an example of a remote control receiver according to the present invention. FIG. 10 is merely an example, and does not limit the configurations of the remote control transmitter according to the present invention and the remote control receiver according to the present invention.

  As shown in FIG. 10, the remote control transmitter 1000 is provided with a plurality of buttons, and a key operation unit 1003 is formed. There is only one power button. On the other hand, the remote control receiver 1010 is a television as shown in FIG. 10, and is provided with a main body power switch 1013 in addition to a display screen.

  The remote control transmitter 1000 includes an infrared transmission unit 1001 and transmits an infrared remote control signal, Bluetooth PIN data, or the like to the infrared reception unit 1011 provided in the remote control receiver 1010. The remote control transmitter 1000 also includes a radio wave transmission / reception unit 1002, transmits a Bluetooth remote control signal or the like to the radio wave transmission / reception unit 1012 provided in the remote control receiver 1010, and the Bluetooth transmission data etc. from the radio wave transmission / reception unit 1012. Receive.

  Although an embodiment in which a remote control signal is transmitted / received using Bluetooth will be described here, the present invention is not limited to Bluetooth, but any remote controller that transmits a signal using radio waves may be ZigBee or other unique devices. It can also be applied to a remote control by a method.

  In the following description of the operation, a system including a remote control transmitter and a remote control receiver as shown in FIG. 10 will be described as a typical example, but the scope of the present invention is not limited to this. In the following description, a system as shown in FIG. 11 may also be mentioned.

  FIG. 11 is a schematic diagram showing the external appearance of a remote control transmitter 1100 which is an example of a remote control transmitter according to the present invention and a remote control receiver 1010 which is an example of a remote control receiver according to the present invention which is also shown in FIG. FIG. FIG. 11 is merely an example, and does not limit the configurations of the remote control transmitter according to the present invention and the remote control receiver according to the present invention.

  Unlike remote control transmitter 1000, remote control transmitter 1100 is provided with two power buttons “ON” and “OFF”. The rest is the same as remote control transmitter 1000.

  Next, operations of the remote control transmitter 100 and the remote control receiver 200 will be described with a focus on power on and off. In the following, the radio wave transmission / reception units 104 and 204 are Bluetooth devices, and PIN codes (first transmitter-side authentication data, second receiver) used in the Bluetooth device as authentication data for pairing are used. Side authentication data) and a link key (first receiver side authentication data, second transmitter side authentication data) will be described, but the present invention is not limited to this, Other wireless technologies may be used.

  When the power of the remote control receiver 200 (operated device such as a TV) is turned off (the remote control may be turned off or the main body power switch may be turned off), the main control unit 210 Prior to turning off the power of the remote control receiver 200, information that “the remote control receiver is turned off” is sent from the radio transmission / reception unit 204 to the radio transmission / reception unit 104 of the remote control transmitter 100. Upon receiving this information, control unit 110 turns off remote control transmitter 100.

  When the remote control receiver 200 is turned off by the remote control signal, the infrared receiving unit 203 of the remote control receiver 200 turns on the remote control signal of “power on” or “switch on / off of power” (the power of the remote control receiver 200 is turned off). (Signal for turning on) can be received (other signals may not be received), and transitions to a low power consumption state (sleep mode), and other parts (infrared receiving unit 203, such as radio wave transmitting / receiving unit 204) The other parts) can be completely turned off.

  Next, processing when the power is turned on will be described with reference to FIG.

  When the key operation unit 107 detects the input of the power button of the remote control key, the remote control transmitter 100 refers to the data of the power supply flg. If “0” (off), the radio wave transmission / reception unit 104 remains powered off. First, the power of the infrared transmitter 103 is turned on, and a remote control signal for turning on the power of the remote control receiver 200 from the infrared transmitter 103 (that is, “a remote control signal for commanding to turn on the power of the remote control receiver”). Or a remote control that generally uses a remote control transmitter having only one power button, such as the remote control transmitter 1000 shown in FIG. Signal ").

  In this specification, the “power supply flg” is data (flag) stored in the internal memory (storage unit 120) of the remote control transmitter 100, and the main control unit 110 has a remote control operation target device (remote control). Used to grasp the power state of the receiver 200). When the power-on / off remote control signal does not reach the remote control receiver 200 properly, the remote control receiver is set so that there is as little discrepancy as possible between the value of the power supply flg and the power state of the remote control receiver 200. When the power supply state of 200 is changed, information (ON or OFF) indicating the state is transmitted to the remote control transmitter 100, and the main control unit 110 changes the value of the power supply flg based on the information. By doing so, the power state of the remote control receiver 200 and the value of the power supply flg held in the remote control transmitter 100 are always controlled to be the same value (on or off).

  When the “power key” attached to the remote control transmitter 100 is not a single key but is divided into “power on key” and “power off key” (see FIG. 11), which power key is pressed? Thus, it can be clearly seen whether the power of the remote control receiver 200 is turned on or off, so that the process of changing the value of the power supply flg, the power supply flg, and the like are not necessary.

  Next, the PIN code (first transmitter side authentication data) generated by the pairing control unit 113 is transmitted from the infrared transmission unit 103. On the other hand, if the remote control receiver 200 is turned off by the remote control, the infrared receiver 203 receives the “power on” (or “switch on / off”) signal by the infrared remote control signal, and then the remote control receiver 200 The power supply of the entire 200 is turned on, and the link key (first receiver side authentication data) generated by the pairing control unit 213 based on the PIN code sent thereafter is transmitted from the radio wave transmitting / receiving unit 204 to the remote control transmitter 100. Send to.

  The radio transmission / reception unit 104 of the remote control transmitter 100 receives the link key transmitted from the remote control receiver 200, and the pairing control unit 113 receives the PIN code generated by the pairing control unit 113 and the radio transmission / reception unit 104. The remote controller receiver 200 is authenticated by comparing with the link key. At this time, the remote control transmitter 100 changes the data of the power supply flg to “1” (ON). Further, the pairing control unit 113 generates a link key (second transmitter side authentication data) based on the PIN code generated by the pairing control unit 113 and transmits the link key from the radio wave transmission / reception unit 104. The remote control receiver 200 authenticates the remote control transmitter 100 using this link key. Note that the transmission of the link key by the remote control transmitter 100 may be performed after reception of the link key from the remote control receiver 200 as shown in FIG. 2, or from the remote control receiver 200 as shown in FIG. It may be performed before receiving the link key.

  Note that authentication is performed by exchanging the link key generated from the PIN code as described above. Specifically, an initialization key is calculated by an initialization key algorithm using a PIN code as an input, and a link key is set using the initialization key. The present invention is intended to create and authenticate authentication data by “sharing certain types of information by both sides using infrared rays”, and it does not necessarily generate a PIN code. It may not be necessary, but may be initialization key generation data, a personal identification number, personal identification data, or the like. The authentication method may be performed in accordance with the Bluetooth standard in the present embodiment, but is not limited to this, and the remote control transmitter performs the first authentication as described in the second embodiment. If the configuration is such that the data is transmitted to the paired remote control receiver by infrared and the first authentication data associated with the first authentication data is returned from the remote control receiver, the remote control transmitter and the remote control reception are provided. Since both of the machines can confirm that the other party has the first authentication data, authentication can be performed.

  After the authentication is completed, the remote control signal can be transmitted by using the radio wave transmission / reception unit 104 thereafter, so that the power of the infrared transmission unit 103 can be turned off. Further, the power of the pairing control unit 113 can be turned off until the time when authentication is required again. When the remote control receiver 200 completes the authentication of the remote control transmitter 100 using the radio wave from the remote control transmitter 100 received by the radio wave transmission / reception unit 204, the power of the infrared reception unit 203 and the pairing control unit 213 is turned on. Can be turned off.

  Here, I would like to reconfirm that sending this PIN code by infrared rays instead of radio waves is an extremely important mechanism for security. This is because if the process of exchanging the PIN code is performed only by radio waves, the remote control receiver 200 may be authenticated by transmitting the PIN code from a malicious person outside the room. That is, as long as the PIN code is transmitted by radio waves, no matter how weak the radio wave output is, the Service-to-Self may use a high-performance antenna or the like. It is difficult to prevent. Incorporating infrared rays into this process makes authentication by such Service-to-Self impossible.

  Next, processing when the power is turned off will be described with reference to FIG.

  When the remote control transmitter 100 senses the input of the power button of the remote control key with the key operation unit 107, the remote control transmitter 100 refers to the value of the power supply flg, and if it is “1” (on), “remote power off” (or “ On / off switching ”) is transmitted. When the “power off” remote control signal and the “power on” remote control signal are the same (for example, in a remote control transmitter having only one power button such as the remote control transmitter of FIG. When the remote control signal and the “power on” remote control signal are the same), the signal corresponding to the “power” button on the remote control (the remote control signal of “on / off switching”) is transmitted regardless of the value of the power supply flg. To do.

  When the remote control receiver 200 receives the power-off signal, it confirms that there is no problem even if the entire remote control receiver 200 is turned off, and then starts the process of turning off the power. Further, when the remote control receiver 200 receives a remote control signal of “ON / OFF switching”, if the remote control receiver 200 is in an on state, it is confirmed that there is no problem even if the entire remote control receiver 200 is turned off. Then, start the process of turning off the power. When it can be confirmed that there is no problem even if the power supply of the entire remote control receiver 200 is turned off, and the power-off process can be completed, a power-off completion notification is transmitted to the remote control transmitter 100. Thereafter, the remote control receiver 200 is in a sleep mode in which power-on with infrared light can be detected in preparation for the next power-on instruction from the remote control (other operation parts of the remote control receiver 200, radio wave transmission / reception unit 204, etc. Shifts to the power off state.

  When receiving the “power-off completion notification” from the remote-control receiver 200, the remote-control transmitter 100 changes the power supply flg to “0” (off), and then issues a command to turn on the power at the remote-control transmitter 100. The remote control transmitter 100 shifts to a sleep mode in which key input can be detected (the other operation parts of the remote control transmitter 100, the radio wave transmission / reception unit 104, etc. are in a power-off state).

  Note that the “power off” or “power on / off switching” signal from the remote control transmitter 100 during the power off process may be transmitted from the infrared transmitter 103. In that case, when receiving the power-off signal in the infrared receiver 203, the remote control receiver 200 starts a process of turning off the power of the remote control receiver 200 as in the case of receiving via radio waves. Similarly, when the remote control receiver 200 receives the remote control signal of “ON / OFF switching” in the infrared receiver 203, the power supply of the entire remote control receiver 200 is turned off if the remote control receiver 200 is in the ON state. After confirming that there is no problem, the process of turning off the power is started.

  A processing sequence when the power-off of the remote control receiver 200 is performed not by the remote control signal from the remote control transmitter 100 but by the power switch of the remote control receiver 200 main body will be described with reference to FIG.

  When the remote control receiver (such as a television) 200 detects that the power button on the main body has been pressed, it transmits a “power-off completion notification” from the radio wave transmission / reception unit 204 to the remote control transmitter 100 before the power is turned off. Thereafter, the remote control receiver 200 shifts to a complete power-off state. The remote control receiver 200 does not necessarily have to be completely turned off. In this case, however, it is assumed that the subsequent power on is not performed by the remote control but only by the main body power switch, and the remote control receiver 200 is set to sleep. In general, the power supply is completely turned off without entering the mode.

  When receiving the “power-off completion notification” from the remote-control receiver 200, the remote-control transmitter 100 changes the power supply flg to “0” (off), and prepares for the subsequent remote-control remote controller 100 to issue a power-on instruction, etc. The mode shifts to a sleep mode in which the key input of the transmitter can be detected (the other operation parts of the remote control transmitter 100, the radio wave transmitting / receiving unit 104, etc. are in a power-off state).

  Contrary to the above, the processing sequence when the power-on of the remote control receiver 200 is performed not by the remote control signal from the remote control transmitter 100 but by the power switch of the remote control receiver 200 main body will be described with reference to FIG. .

When the remote control receiver (such as a television) 200 detects that the power button of the main body has been pressed, when the power is turned on, the remote control receiver 200 can perform power on processing (when the remote control receiver 100 and the remote control receiver 100 are connected). If the pairing is not canceled), a “power-on completion notification” is transmitted to the remote control transmitter 100 by radio waves. When receiving the “power-on completion notification” from the remote-control receiver 200, the remote control transmitter 100 changes the power supply flg to “1” (on). (If pairing is not canceled between the remote control receiver 200 and the remote control transmitter 100, the remote control operation with radio waves can be continued thereafter.)
When the pairing is canceled between the remote control transmitter 100 and the remote control receiver 200, the power status cannot be transmitted by radio waves. In this case, the “power-on completion notification” is transmitted. Absent. At this time, a mismatch occurs between the value of the power supply flg of the remote control transmitter 100 and the power supply state of the remote control receiver 200 (the power supply flg is “0” (off), and the remote control receiver is turned on. .) However, this is solved when the user subsequently performs a remote control operation with the remote control transmitter 100. This mechanism will be described with reference to FIG.

  At this time, when the user performs any operation on the remote control transmitter 100, a remote control signal corresponding to the operation is transmitted by infrared rays. In the case of infrared rays, since there is directivity, the remote control receiver 200 does not react unless the remote control is pointed at the remote control receiver (such as a television) 200, so the user naturally points the remote control at the remote control receiver 200.

  When the remote control receiver 200 receives the remote control signal, the remote control signal 200 performs processing (channel change, volume up / down, etc.) corresponding to the remote control signal, and then the PIN code (first transmitter side authentication data) from the remote control transmitter 100. Is transmitted by infrared. The remote control receiver 200 returns a link key (first receiver side authentication data) generated based on the PIN code received by infrared rays by radio waves.

  The remote control transmitter 100 authenticates the remote control receiver 200 using the link key returned by radio waves, and turns the power supply flg of the storage unit 120 to “1” (ON). Thereafter, the sequence is the same as that described in FIG. In this way, the value of the power supply flg and the power supply state of the remote control receiver 200 can be matched. Note that the remote control transmitter 100 may transmit the link key generated by itself to the remote control receiver 200 before receiving the link key from the remote control receiver 200 as in the sequence described with reference to FIG.

  In addition, in FIG. 6, when the remote control transmitter 100 cannot normally receive the “power off completion notification”, the power supply flg of the remote control transmitter 100 is “1” (on), but the power supply of the remote control receiver 200 is A situation occurs that is turned off. In this case, after that (while the power of the remote control receiver 200 is off), radio waves from the remote control transmitter 100 are not received by the remote control receiver 200. When it is confirmed by the time measuring function (not shown) that communication cannot be performed for a certain period, the transmission side radio wave transmitting / receiving unit of the remote control transmitter 100 enters a timeout state. At this time, remote control transmitter 100 (main control unit 110 thereof) changes power supply flg to “0” (off). This is an example of a mechanism for detecting the power supply state of the remote control receiver. Thus, in this case as well, the value of the power supply flg and the power supply state of the remote control receiver can be matched.

  The pairing may be performed any time as long as the authentication is completed immediately before the remote control operation. For example, pairing may be performed before the process of sending a remote control signal when the user performs some remote control operation without performing pairing immediately after the power is turned on.

  Normally, once pairing is performed, pairing is not required again until the power is turned off, but the number of devices that can be paired may be limited depending on the model. In the case of such a model, pairing may be cut off even when the power is turned on, and pairing may be necessary again. Even in this case, pairing may be performed before the process of sending the remote control signal.

  Also, when the power is turned off, the MAC address and link key are saved in a non-volatile memory such as a flash memory, and when the power is turned on, these values are used to enable reconnection. Sometimes you don't have to pair every time.

(Second Embodiment)
In the second embodiment of the present invention, the operations of the pairing control unit 113 and the pairing control unit 213 are different from those of the first embodiment. The description of the other parts is the same as in the first embodiment.

  FIG. 5 is a sequence diagram illustrating control when the system according to the present embodiment is turned on. When remote controller transmitter 100 detects that the “power” button of the remote controller key is pressed by key operation unit 107, remote controller transmitter 100 refers to the data of power supply flg, and if “0” (off), radio wave transmitter / receiver 104 and infrared transmitter 103, and the infrared transmitter 103 sends a “remote control signal for instructing to turn on the remote control receiver” or a “remote control signal for instructing to turn on / off the remote control receiver”. Send.

  The remote control receiver 200 receives the “remote control signal instructing to turn on the remote control receiver” by the infrared remote control signal in the infrared receiving unit 203 or when the remote control receiver 200 is off. When the “remote control signal instructing to switch on / off the power supply of the remote control receiver” is received by the infrared remote controller, power supply to the entire remote control receiver 200 is started. Next, the pairing control unit 213 generates a PIN code (second receiving-side authentication data), and transmits the generated PIN code from the radio wave transmission / reception unit 204.

  On the other hand, the remote control transmitter 100 receives the PIN code at the radio wave transmission / reception unit 104, and the pairing control unit 113 sends the PIN code (first transmitter side authentication data) from the infrared transmission unit 103. While transmitting to the remote control receiver, the value of the power supply flg is changed to “1” (ON).

  In the remote control receiver 200, the PIN code transmitted from the infrared transmission unit 103 of the remote control transmitter 100 is received by the infrared reception unit 203, and the pairing control unit 213 receives the received PIN code (on the first transmitter side). After the remote control transmitter 100 is authenticated by comparing the authentication data) with the PIN code (second receiver side authentication data) generated by the pairing control unit 213, the radio wave transmission / reception unit 204 receives the PIN. The link key (first receiver side authentication data) generated from the code is transmitted.

  After the authentication is completed, since the remote control signal can be transmitted and received using the radio wave transmitting / receiving unit 204 thereafter, the power of the infrared receiving unit 203 can be turned off. Until the time when authentication is required again, the power of the pairing control unit 213 can be turned off. The remote control transmitter 100 also turns off the power of the infrared transmission unit 103 and the pairing control unit 113 when authentication of the remote control receiver 200 is completed based on the link key received by the radio wave transmission / reception unit 104. I can leave.

  When transmitting a power-on signal, the remote control transmitter 100 needs to face the remote control receiver 200 (since infrared rays have directivity). Since there is no burden on the user (the user does not have to worry about pointing the remote control transmitter 100 toward the remote control receiver 200 when sending the PIN code), the infrared of the PIN code is used. Can be transmitted.

  Thus, in the system according to the present embodiment, the PIN code is returned by infrared rays instead of radio waves. This is a very important mechanism for security. This is because if the process of exchanging the PIN code is performed only by radio waves, the remote control receiver 200 may be authenticated by returning the PIN code from a malicious person outside the room. Incorporating infrared rays into this process makes authentication by such Service-to-Self impossible.

  The control when the power is turned off is the same as in the first embodiment, but when the remote control transmitter 100 is powered on with the power flg “0” (off), the user then performs remote control transmission. The control for resolving the inconsistency by operating the remote control with a machine is slightly different. This will be described with reference to FIG.

  In the state where the power supply flg is “0” (off) and the remote control receiver is turned on, if the user performs any operation on the remote control transmitter 100, the remote control signal corresponding to the operation is transmitted by infrared rays. . In the case of infrared rays, since there is directivity, the remote control receiver 200 does not react unless the remote control is pointed at the remote control receiver (such as a television) 200, so the user naturally points the remote control at the remote control receiver 200.

  When receiving the remote control signal, the remote control receiver 200 performs processing (channel change, volume up / down, etc.) corresponding to the remote control signal. Thereafter, a PIN code (second receiver side authentication data) is generated, and the PIN code is transmitted from the radio wave transmission / reception unit 204. When the radio transmitter / receiver 104 receives the PIN code, the remote control transmitter 100 turns the power supply flg to “1” (ON), and the pairing control unit 113 uses the same PIN code (first transmission) as the received PIN code. Machine side authentication data) is transmitted from the infrared transmitter 103. The remote control receiver 200 authenticates the remote control transmitter using the PIN code returned by infrared rays. Thereafter, the sequence is the same as that described with reference to FIG. In this way, the value of the power supply flg and the power supply state of the remote control receiver 200 can be matched.

  As described above, the remote control receiver 200 and the remote control transmitter 100 in the system according to the present embodiment can reduce standby power, and can automatically generate a PIN code for authentication. It is also possible to automate pairing.

  In addition, once a radio wave connection is established (the password is sent and received to authenticate the remote control and the device), the remote control signal can be sent by radio wave thereafter, allowing remote control operation independent of direction. In addition, the power of the infrared device can be turned off, and the power consumption can be reduced.

(Third embodiment)
FIG. 12 is a schematic diagram showing an outline of a system according to the third embodiment of the present invention. The remote control transmitter 100 is the same as the remote control transmitter 100 according to the first embodiment. The remote control transmitter 300 includes an infrared receiver (transmitter side infrared receiver) 302 in addition to the configuration of the remote controller transmitter 100 (infrared transmitter 304 and the like).

  As described above, remote control transmitter 100 transmits a PIN code (first transmitter side authentication data) from infrared transmission unit 103, but remote control transmitter 300 receives the PIN code at infrared reception unit 302. To do. The pairing control unit 313 of the remote control transmitter 300 causes the received PIN code to be transmitted from the infrared transmission unit 304 in the same manner as the PIN code generated in the first embodiment.

  By adopting such a mechanism, it becomes possible to exchange the Bluetooth PIN code between the remote control transmitters without explicitly showing it to the user. That is, the PIN code can be exchanged between the remote control transmitters while keeping it secret to the user.

  In addition, since the exchange of personal identification data by infrared rays can use IrSS to make it look like image data (JPEG data) to the user, It also has the effect of preventing you from being realized.

Finally, the main control unit 110 included in the remote control transmitter 100, the main control unit 210 included in the remote control receiver 200, and the main control unit 310 included in the remote control transmitter 300 are performed by hardware logic.

  The object of the present invention can also be achieved by configuring main control units 110, 210, and 310 (or remote control transmitter 100, remote control receiver 200, and remote control transmitter 300) to be connectable to a communication network. In this case, the program code is supplied to the main control units 110, 210 and 310 via the communication network. The communication network is not limited to a specific type or form as long as it can supply program codes to the main control units 110, 210, and 310. For example, the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, etc. may be used.
