Description

[Technical Field]

[0001] The present invention relates to an information output device and the like. [Background technology]

[0002] In wireless communication, one of the factors that reduces throughput is radio interference.

[0003] When radio wave interference occurs and throughput decreases, the quality of the services provided by wireless communication may be degraded, such as distortion of the video and audio being played back or a deterioration in the accuracy of remote control.

[0004] Therefore, when radio wave interference occurs, it is desirable to take measures to resolve the radio wave interference.

[0005] However, there may be other factors besides radio interference that cause a decrease in throughput. Therefore, in order to take measures against radio interference, it is first necessary to investigate whether radio interference is occurring.

[0006] A decrease in throughput is generally detected when a decrease in service quality occurs. Generally, an investigator visits the site where the decrease in service quality occurs and investigates the surrounding radio wave conditions to determine whether radio wave interference is occurring. If radio wave interference is detected, countermeasures are taken to address it.

[0007] Further, related techniques include those described in Patent Documents 1 and 2. [Prior art documents] [Patent documents]

[0017] [First embodiment] A first embodiment of the present invention will be described.

[0018] A specific example of the information output device 10 in the first embodiment is an information output device 20 in a second embodiment, which will be described later.

[0019] First, a configuration example of the information output device 10 of this embodiment will be described. Fig. 1 shows a configuration example of the information output device 10 of this embodiment. The information output device 10 includes a receiving unit 11, an estimating unit 12, an acquiring unit 13, and an output unit 14.

[0020] The receiving unit 11 (receiving means) receives quality information from the wireless communication means. The wireless communication means performs wireless communication. The quality information is information about the quality of the communication in use. The communication in use is the wireless communication being used by the wireless communication means.

[0021] The estimation unit 12 (estimation means) estimates the occurrence of radio wave interference with the communication in use based on the quality information.

[0022] The acquisition unit 13 (acquisition means) acquires alternative communication information from the storage means when it is estimated that radio wave interference with the communication in use will occur. The storage means stores communication information for each wireless communication that can be used by the wireless communication means. The communication information is information related to wireless communication. The alternative communication is wireless communication that can be used by the wireless communication means instead of the communication in use. The alternative communication information is communication information for the alternative communication.

[0023] The wireless communication that the wireless communication means can use instead of the used communication is wireless communication that uses a wireless communication method different from the used communication, or wireless communication that is provided by a carrier different from the used communication.

[0024] The output unit 14 (output means) outputs output information including the alternative communication information.

[0025] Next, an example of the operation flow of the information output device 10 of this embodiment will be described. Fig. 2 shows an example of the operation flow of the information output device 10 of this embodiment.

[0026] The receiving unit 11 receives quality information from the wireless communication means (step S101). The estimating unit 12 estimates the occurrence of radio wave interference with the communication in use based on the quality information (step S102). The acquiring unit 13 acquires alternative communication information from the storage means when it is estimated that radio wave interference with the communication in use will occur (step S103). The output unit 14 outputs output information including the alternative communication information (step S104).

[0027] As described above, in the first embodiment of the present invention, the information output device 10 includes a receiving unit 11, an estimating unit 12, an acquiring unit 13, and an output unit 14. The receiving unit 11 receives quality information from a wireless communication means. The wireless communication means performs wireless communication. The quality information is information about the quality of the used communication. The used communication is wireless communication used by the wireless communication means. The estimating unit 12 estimates the occurrence of radio wave interference with the used communication based on the quality information. The acquiring unit 13 acquires alternative communication information from a storage means when the occurrence of radio wave interference with the used communication is estimated. The storage means stores communication information for each wireless communication usable by the wireless communication means. The communication information is information about wireless communication. The alternative communication is wireless communication that the wireless communication means can use instead of the used communication. The alternative communication information is communication information about the alternative communication. The wireless communication that the wireless communication means can use instead of the used communication is wireless communication that uses a wireless communication method different from the used communication or wireless communication provided by a different operator from the used communication. The output unit 14 outputs output information including the alternative communication information.

[0028] In this way, when it is estimated that radio wave interference with the communication in use is occurring, the information output device 10 outputs information including communication information of a radio communication that the radio communication means can use instead of the communication in use. Since the information of a radio communication that the radio communication means can use instead of the communication in use is output from the information output device 10, the user can refer to the output information and change the radio communication used by the radio communication means from the communication in use to another radio communication. As a result, the possibility of avoiding radio wave interference and continuing communication is improved. Furthermore, the user can more easily deal with radio wave interference. Therefore, it is possible to output information that makes it easier to deal with radio wave interference.

[0029] [Second embodiment] Next, an information output device 20 according to a second embodiment of the present invention will be described. Note that the information output device 20 according to the second embodiment is a specific example of the information output device 10 according to the first embodiment.

[0030] 3 shows an example of the configuration of a system including the information output device 20 of this embodiment. The information output device 20 is connected to a wireless communication means 40. The information output device 20 is also connected to a display means 60. The information output device 20 is also connected to a storage means 50. The storage means 50 and the wireless communication means 40 may be included in the information output device 20.

[0031] The information output device 20, the storage means 50, the wireless communication means 40, and the display means 60 are included in, for example, a mobile object 70. The mobile object 70 is, for example, an airplane, a ship, or a mobile phone.

[0032] The wireless communication means 40 performs wireless communication. The wireless communication means 40 can use two or more wireless communications. The wireless communication means 40 can use any type of wireless communication. Wireless communication that the wireless communication means 40 can use includes, for example, various types of mobile communication, business wireless communication, optical wireless communication (infrared communication, visible light communication, etc.), short-range wireless communication, etc. In this embodiment, wireless communication using different wireless communication methods is treated as different wireless communication. Furthermore, wireless communication using the same wireless communication method but provided by different service providers is treated as different wireless communication.

[0033] The wireless communication means 40 transmits quality information to the information output device 20. The quality information is information relating to the quality of the communication in use. The communication in use is the wireless communication used by the wireless communication means 40. The quality information is, for example, a received signal level, throughput, PER (Packet Error Rate), BER (Bit Error Rate), SINR (Signal to Interference Plus Noise Ratio), etc.

[0034] The storage means 50 stores communication information for each wireless communication that can be used by the wireless communication means 40. The communication information is information related to wireless communication, and includes, for example, information such as the name, frequency band used, and communication method.

[0035] The display means 60 is a man-machine interface such as a display serving as an output device. The display means 60 displays an image. In this embodiment, the information output device 20 outputs output information to the display means 60. However, the output destination of the output information is arbitrary. The information output device 20 may output the output information to an output destination other than the display means 60.

[0036] 4 shows an example of the configuration of the information output device 20 of this embodiment. The information output device 20 of this embodiment includes a receiving unit 21, an estimating unit 22, an acquiring unit 23, and an output unit 24.

[0037] The receiving unit 21 receives quality information of the used communication from the wireless communication means 40. The used communication is wireless communication used by the wireless communication means 40. The quality information is information relating to the quality of the used communication.

[0038] The estimation unit 22 estimates the occurrence of radio wave interference with the communication in use based on the quality information.

[0039] The estimation unit 22 performs estimation based on estimation conditions. The estimation conditions are conditions that are met when radio wave interference is occurring. The estimation conditions also include conditions related to quality information received from the wireless communication means 40. The estimation unit 22 estimates that radio wave interference is occurring when the estimation conditions are met. The estimation unit 22 estimates that radio wave interference is not occurring when the estimation conditions are not met. The method for estimating radio wave interference will be described later.

[0040] When it is estimated that radio wave interference with the communication in use will occur, the acquisition unit 23 acquires alternative communication information from the storage means 50. The alternative communication information is information relating to the alternative communication. The alternative communication is wireless communication that the wireless communication means 40 can use instead of the communication in use. The alternative communication information is communication information of the alternative communication. A method for acquiring the alternative communication information will be described later.

[0041] The output unit 24 outputs output information including alternative communication information. In this embodiment, the output unit 24 outputs the output information to the display means 60. In addition, in this embodiment, the output information is image information for causing the display means 60 to display an image showing information related to the alternative communication. In other words, the output unit 24 causes the display means 60 to display an image showing information related to the alternative communication by outputting the output information to the display means 60.

[0042] Furthermore, the output unit 24 may instruct the wireless communication means 40 to use an alternative communication. In this case, the output information may be instruction information that indicates an instruction to the wireless communication means 40. Furthermore, when an instruction input instructing the use of one of the alternative communications is made, the output unit 24 may instruct the wireless communication means 40 to use the instructed alternative communication.

[0043] Next, examples of estimation conditions will be described.

[0044] The estimation condition is, for example, that the received signal level is equal to or greater than a first threshold and the throughput is equal to or less than a second threshold. This condition indicates that the signal level is sufficient but the throughput is reduced. In such a case, there is a high possibility that radio interference is occurring. Note that the estimation condition may use SINR instead of throughput.

[0045] Alternatively, the estimation condition may be that the received signal level is equal to or greater than a first threshold and that the PER is equal to or greater than a third threshold. The estimation condition may be a BER instead of a PER.

[0046] Furthermore, for example, the estimation condition may be a condition based on date, time, and location. For example, it is known that radio wave interference occurs at a specific location due to the passage of an interference source at a specific time on a specific day of the week. In such a case, the estimation condition may be a specific time (time zone) on a specific day of the week for the specific location.

[0047] When location information is used, the information output device 20 can grasp the position of the wireless communication means 40 by using the GNSS (Global Navigation Satellite System) or the like. Alternatively, the wireless communication means 40 may grasp the position information of the wireless communication means 40 by using the GNSS or the like, and the information output device 20 may receive the position information of the wireless communication means 40 from the wireless communication means 40.

[0048] The estimation conditions may also be generated based on a history of past estimation results. For example, the estimation unit 22 stores information on the date, time, and location where radio wave interference is estimated to be occurring in the storage means 50. Then, the condition generation unit 35 generates conditions for the date, time, and location where radio wave interference is estimated to be occurring based on the history of information on the date, time, and location where radio wave interference is estimated to be occurring. The condition generation unit 35 may be included inside the information output device or may be external to the information output device 20. The condition generation unit 35 may also generate the estimation conditions by machine learning, for example. Note that FIG. 5 shows an example configuration of the information output device 30 including the condition generation unit 35.

[0049] The estimation condition may be a combination of two or more of the individual estimation conditions described above. Hereinafter, the individual estimation condition will be referred to as an individual condition. For example, the estimation condition may be the satisfaction of one or more of the individual conditions, or the satisfaction of a predetermined number or more of the individual conditions.

[0050] Next, a method for acquiring alternative communication information will be described.

[0051] The acquisition unit 23 acquires alternative communication information, which is communication information of alternative communication, from the storage means 50. The storage means 50 stores communication information for each wireless communication that can be used by the wireless communication means 40. Note that, among the wireless communications for which resource candidates are stored in the storage means 50, wireless communications excluding the in-use communication are called alternative candidates. The alternative candidates are wireless communications that can be used by the wireless communication means 40 excluding the in-use communication.

[0052] When there is one alternative candidate, the acquisition unit 23 may acquire the communication information of the alternative candidate as the alternative communication information. When there are two or more alternative candidates, the acquisition unit 23 may acquire the communication information of all or some of the alternative candidates as the alternative communication information.

[0053] Furthermore, the acquisition unit 23 may set wireless communication having a longer communication distance than the distance between the wireless communication means 40 and the communication partner as the alternative communication. In this case, the acquisition unit 23 acquires, from the communication information of the alternative candidates, communication information of wireless communication having a longer communication distance than the distance between the wireless communication means 40 and the communication partner as the alternative communication information. The communication partner is a connection destination of the wireless communication performed by the wireless communication means 40. For example, when wireless communication is performed via a base station, an access point, or the like, the communication partner is the base station, the access point, or the like. When wireless communication is performed between terminals without via a base station, an access point, or the like, the communication partner is the opposing terminal.

[0054] When the acquisition unit 23 compares the distance between the wireless communication means 40 and the communication partner with the communicable distance, the communication information stored in the storage means 50 includes information on the communicable distance.

[0055] In this way, the acquisition unit 23 can acquire, as the alternative communication information, communication information of a wireless communication with which the communication partner is within a communicable distance. Therefore, the acquisition unit 23 can set, as the alternative communication information, communication information of a wireless communication with a high probability of communication among the alternative candidates. This further improves the convenience for the user.

[0056] The acquisition unit 23 can calculate the distance between the wireless communication means 40 and the communication partner based on the location information of the communication partner and the location information of the wireless communication means 40. More specifically, the acquisition unit 23 can calculate the distance between the wireless communication means 40 and the communication partner as follows.

[0057] If the location of the communication partner is fixed, the acquisition unit 23 may acquire the location information of the communication partner from the storage means 50. In this case, the storage means 50 stores the location information of the communication partner in association with each wireless communication that can be used by the wireless communication means 40. Note that if the location information of two or more communication partners is stored in the storage means 50 for one wireless communication, the acquisition unit 23 may compare the communication distance with the communication partner that is closest to the location of the wireless communication means 40.

[0058] Furthermore, when the wireless communication means 40 is installed on a ship, an aircraft, or the like, the position information of ships, etc. belonging to the same group may be exchanged through a communication different from the communication in use. When the communication partner is installed on such a ship, etc., the acquisition unit 23 may use the position information obtained through the communication different from the communication in use as the position information of the communication partner.

[0059] Furthermore, the acquisition unit 23 may, for example, select wireless communication using a frequency that is not used at the location of the wireless communication means 40 as the alternative communication. In this case, the acquisition unit 23 acquires, from the communication information of alternative candidates, communication information of wireless communication using a frequency that is not used at the location of the wireless communication means 40 as the alternative communication information. In this case, the wireless communication means 40 may have a function of investigating unused frequencies, such as a spectrum analysis function. Then, the acquisition unit 23 may cause the wireless communication means 40 to investigate unused frequencies.

[0060] Furthermore, the acquisition unit 23 may cause the wireless communication means 40 to attempt communication using an alternative candidate, and may set the alternative candidate with which the wireless communication means 40 can communicate as the alternative communication. In this case, the acquisition unit 23 acquires, from the communication information of the alternative candidate, communication information of wireless communication with which the wireless communication means 40 can communicate as the alternative communication information. The wireless communication means 40 can attempt communication using the alternative candidate by, for example, transmitting trial data to the communication partner.

[0061] Furthermore, the acquiring unit 23 may select a wireless communication having a communication frequency lower than a predetermined frequency from among the alternative candidates as the alternative communication. In this case, the acquiring unit 23 acquires communication information of the wireless communication having a communication frequency lower than the predetermined frequency as the alternative communication information. Furthermore, the receiving unit 21 may receive information on the communication frequency of the alternative candidate from the wireless communication means 40.

[0062] Furthermore, the acquisition unit 23 may acquire the alternative communication information based on a past history of information on available frequencies. For example, the storage unit 50 further stores a past history of information on available frequencies. Then, the acquisition unit 23 may select, from among the alternative candidates, wireless communication using a frequency that was previously available at the location of the wireless communication unit 40 as the alternative communication. The acquisition unit 23 acquires communication information of the alternative communication as the alternative communication information. In this case, the communication information of the alternative communication is communication information of wireless communication using a frequency that was previously available at the location of the wireless communication unit 40, from among the communication information of the alternative candidates.

[0063] The past history of information on available frequencies may be based on, for example, the results of spectrum analysis by the wireless communication means 40. The past history of information on available frequencies may also be information on wireless communications that were previously available by the wireless communication means 40. In this case, the wireless communication means 40 can collect multiple correspondences between spatial positions, dates and times, and information on available frequencies as the mobile object 70 equipped with the wireless communication means 40 moves.

[0064] Furthermore, the past history of available frequency information may be information on available frequencies acquired by wireless communication means mounted on another mobile body or a fixedly installed information acquisition device. In this case, the information acquisition device has a function for investigating available frequencies (for example, a spectrum analysis function). In this case, the available frequency information acquired by the other wireless communication means or the fixedly installed information acquisition device may be collected by a management device (not shown). The storage means 50 may then store the information collected by the management device as a past history of available frequency information.

[0065] The acquisition unit 23 may also estimate a currently available frequency based on a past history of information about available frequencies. For example, the acquisition unit 23 estimates a frequency that can be used at the current date and time and the current location of the wireless communication means 40 based on the history of information about available frequencies. The acquisition unit 23 acquires communication information about an alternative communication as the alternative communication information. In this case, the alternative communication is wireless communication that uses a frequency that can be used at the current date and time and the current location of the wireless communication means 40, among alternative candidates. The acquisition unit 23 may use machine learning to estimate an available frequency. For example, the acquisition unit 23 may estimate an available frequency using an estimation model that estimates an available frequency. In this case, when date and time information and location information are input, the estimation model outputs information about a frequency that can be used at the date and time and location. The information output device 20 may include a model generation unit (not shown) that generates an estimation model.

[0066] A plurality of methods for acquiring alternative communication information have been described above. The acquisition unit 23 can acquire the alternative communication information by one or more of the above-described methods. When acquiring the alternative communication information by two or more methods, the acquisition unit 23 can acquire the alternative communication information, for example, as follows. For example, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication that satisfies any one or more of two or more acquisition conditions. Furthermore, for example, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication that satisfies a predetermined number or more of the two or more acquisition conditions. Note that the acquisition conditions are wireless communication conditions for acquiring communication information as alternative communication information in each method. The acquisition conditions are conditions in the above-described methods, such as a condition based on distance, a condition based on communication availability, a condition based on communication frequency, etc.

[0067] Next, a specific example of an image that the output unit 24 causes the display means 60 to display will be described.

[0068] For example, the image may include alternative communication information. Furthermore, when the acquisition unit 23 acquires two or more pieces of alternative communication information, the image may include a screen item for inputting an instruction to use any one of the pieces of alternative communication information.

[0069] Fig. 6 is a diagram showing an example of an image that the output unit 24 displays on the display means 60. In the example of Fig. 6, the image includes multiple names of alternative communications. Also, in the example of Fig. 6, radio buttons are screen items for inputting instructions to use one of the multiple alternative communications.

[0070] Furthermore, when an instruction input instructing the use of one of the alternative communications is made, the output unit 24 may instruct the wireless communication means 40 to use the instructed alternative communications. In this case, the instruction input is input to the output unit 24 by a user operating a screen item.

[0071] When the number of pieces of alternative communication information acquired by the acquisition unit 23 is two or more, the display order of the alternative communication information included in the image can be any order. For example, the display order may be a predetermined order of priority. Alternatively, the display order may be an order of decreasing communication frequency.

[0072] The display order may also be in order of communication quality. In this case, the acquisition unit 23 causes the wireless communication means 40 to perform communication via alternative communication. Then, the reception unit 21 receives information on the communication quality of the communication via alternative communication. The output unit 24 rearranges the alternative communication information included in the image in order of highest communication quality.

[0073] Also, for example, the image may include a screen item indicating the wireless communication means 40 at the position of the wireless communication means 40 on the map. In this case, the image may include a screen item indicating the connection destination at the position of the connection destination (connection partner) on the map. Note that the connection destination in this case is a connection destination to which the wireless communication means 40 connects using alternative communication. Furthermore, if the position of the connection destination is unknown or if the position of the connection destination is not included on the map, the display position on the image of the screen item indicating the connection destination is arbitrary.

[0074] The image may also include at least a portion of the alternative communication information for each alternative communication. For example, the image may include the name of the alternative communication, the frequency used, etc. The image may also include information on the communication frequency of each alternative communication. The image may also include information on the communication quality of each alternative communication.

[0075] FIG. 7 shows an example of an image that the output unit 24 displays on the display means 60. In the example of FIG. 7, the image includes a screen item indicating the wireless communication means 40. The image also includes screen items indicating connection destinations for each alternative communication. Each screen item may be distinguished by color, pattern, or the like. In the example of FIG. 7, the communication to be used is indicated by a solid line. The alternative communication is indicated by a dashed line. The dashed line may be a screen item for inputting an instruction to use the alternative communication. For example, when a dashed line is selected by a user's operation, an instruction to use the alternative communication corresponding to the dashed line may be input.

[0076] Furthermore, the output unit 24 may output the output information to an output destination other than the display means 60. For example, the output information may be data including information related to alternative communication.

[0077] Next, an example of the operation flow of the information output device 20 of this embodiment will be described. Fig. 8 shows an example of the operation flow of the information output device 20 of this embodiment.

[0078] The receiving unit 21 receives quality information from the wireless communication means 40 (step S201). In this embodiment, the quality information is transmitted from the wireless communication means 40 at predetermined time intervals.

[0079] The estimation unit 22 estimates the occurrence of radio wave interference with the communication in use based on the quality information (step S202). In this embodiment, the estimation is performed at predetermined time intervals.

[0080] When it is estimated that radio wave interference with the communication in use will occur (YES in step S203), the acquisition unit 23 acquires alternative communication information from the storage means 50 (step S204). The output unit 24 outputs output information including the alternative communication information (step S205). Furthermore, for example, when there is no alternative communication information acquired by the acquisition unit 23, the output unit 24 may output information indicating that radio wave interference is occurring but there is no alternative communication. Furthermore, the output unit 24 may output the output information when requested by a device to which the alternative communication information is to be output.

[0081] As described above, in the second embodiment of the present invention, the information output device 20 includes a receiving unit 21, an estimating unit 22, an acquiring unit 23, and an output unit 24. The receiving unit 21 receives quality information from a wireless communication means. The wireless communication means performs wireless communication. The quality information is information about the quality of the used communication. The used communication is wireless communication used by the wireless communication means. The estimating unit 22 estimates the occurrence of radio wave interference with the used communication based on the quality information. The acquiring unit 23 acquires alternative communication information from a storage means when the occurrence of radio wave interference with the used communication is estimated. The storage means stores communication information for each wireless communication usable by the wireless communication means. The communication information is information about wireless communication. The alternative communication is wireless communication that the wireless communication means can use instead of the used communication. The alternative communication information is communication information about the alternative communication. The wireless communication that the wireless communication means can use instead of the used communication is wireless communication that uses a wireless communication method different from the used communication, or wireless communication provided by a different operator from the used communication. The output unit 24 outputs output information including the alternative communication information.

[0082] In this way, when it is estimated that radio wave interference with the communication in use is occurring, the information output device 20 outputs information including communication information of a radio communication that the radio communication means can use instead of the communication in use. Since the information of a radio communication that the radio communication means can use instead of the communication in use is output from the information output device 20, the user can refer to the output information and change the radio communication used by the radio communication means from the communication in use to another radio communication. As a result, the possibility of avoiding radio wave interference and continuing communication is improved. Furthermore, the user can more easily deal with radio wave interference. Therefore, it is possible to output information that makes it easier to deal with radio wave interference.

[0083] In addition, in this embodiment, the acquisition unit 23 may acquire, as alternative communication information, communication information of wireless communication having a communication distance longer than the distance between the wireless communication means 40 and the communication partner to which the wireless communication means 40 is connected via wireless communication.

[0084] In the present embodiment, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication that uses a frequency that is not used in the location where the wireless communication means 40 is located.

[0085] In the present embodiment, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication with which the wireless communication means 40 was able to communicate.

[0086] In the present embodiment, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication whose communication frequency is lower than a predetermined frequency.

[0087] In the present embodiment, the acquisition unit 23 may acquire, as the alternative communication information, communication information of wireless communication using a frequency that was previously available at the location of the wireless communication means 40.

[0088] Furthermore, in this embodiment, the acquisition unit 23 may estimate, based on a past history of information on available frequencies, frequencies that can be used at the current date and time and at the location of the wireless communication means 40. Furthermore, the acquisition unit 23 may acquire, as the alternative communication information, communication information for wireless communication that uses frequencies that can be used at the current date and time and at the current location of the wireless communication means 40.

[0089] As a result, the information output device 20 can present wireless communication that is likely to be available to the user as an alternative communication.

[0090] In addition, in this embodiment, when a plurality of pieces of alternative communication information are acquired, the output information includes the alternative communication information in the order of priority, communication frequency, and communication quality, thereby improving convenience for users.

[0091] In this embodiment, the output unit 24 outputs output information to the display means 60, which displays an image. The output information is image information for displaying the image on the display means 60. The image includes a screen item for inputting an instruction to use the alternative communication. This allows the user to more easily switch to the alternative communication.

[0092] In this embodiment, the image further includes a screen item indicating the wireless communication means 40 at the position of the wireless communication means 40 on the map, and also includes a screen item indicating the connection destination at the position on the map of the connection destination to which the wireless communication means 40 will connect using the alternative communication. This allows the user to grasp the position of the connection destination in the alternative communication and determine whether or not to switch to the alternative communication.
