Summary of the Invention

Problems to be Solved by the Invention

[0004] The disclosure of the above prior art documents is incorporated herein by reference. The following analysis was made by the present inventor.

[0005] However, Patent Document 1 does not disclose a method for setting information necessary for establishing communication between a communication device such as a plurality of IP telephones and a network connection device such as a wireless LAN access point (LAN-AP (Local Area Network Access Point)).

[0006] An object of the present disclosure is to contribute to automatically setting information required for network connection to a plurality of communication devices in view of the above problems.

Means for Solving the Problems

[0007] From a first perspective of this disclosure, a communication device is provided that includes an information communication device that receives communication establishment information used to establish communication with a wireless connection device connected to a network via a first wireless communication line, and a voice communication device that, in response to a voice request to transmit the communication establishment information received via a second wireless communication line, transmits the communication establishment information by voice via the second wireless communication line when the voice communication establishment information is being received via the first wireless communication line or the second wireless communication line.

[0008] A second aspect of this disclosure provides a communication method using a communication device comprising one or more processors, an information communication device, and a voice communication device. The communication method involves causing the one or more processors to cause the information communication device to receive communication establishment information used to establish communication with a wireless connection device connected to a network via a first wireless communication line, and causing the voice communication device to transmit the communication establishment information by voice via the second wireless communication line in response to a voice request for transmission of the communication establishment information received via a second wireless communication line, if the voice communication device has received the communication establishment information via the first wireless communication line or the second wireless communication line.

[0009] A third aspect of this disclosure provides a program to be executed in a communication device comprising one or more processors, an information communication device, and a voice communication device. The program causes the one or more processors to perform a process of causing the information communication device to receive communication establishment information used to establish communication with a wireless connection device connected to a network via a first wireless communication line, and causes the voice communication device to perform a process of causing the voice communication device to transmit the communication establishment information via the second wireless communication line in response to a voice transmission request for the communication establishment information received via a second wireless communication line, if the voice communication device has received the communication establishment information via the first wireless communication line or the second wireless communication line. This program can be recorded on a computer-readable storage medium. The storage medium may be non-transitory, such as semiconductor memory, hard disks, magnetic recording media, or optical recording media. This disclosure can be embodied as a computer program product. [Effects of the Invention]

[0010] From each perspective of this disclosure, it is possible to contribute to the automatic configuration of information required for network connectivity to multiple communication devices. [Brief explanation of the drawing]

[0012] Embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to the embodiments described below. In each drawing, identical or corresponding elements are appropriately denoted by the same reference numeral, and identical or corresponding processes and communications are appropriately denoted by the same reference numeral. In addition, subscripts may be added to the reference numerals and information symbols of multiple possible components, but subscripts may be omitted when one of the multiple possible components is shown without being specified. Furthermore, it should be noted that the drawings are schematic, and the quantity and positional relationships of each element may differ from reality, and the positional relationships and numbers of each element may also differ between drawings. In addition, the connecting lines between blocks such as drawings referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows schematically indicate the flow of the main signal (data) and do not exclude bidirectionality. Also, in the following description, information and data are not strictly distinguished. Furthermore, for the sake of clarity, thresholds are sometimes written as "less than or equal to" and "less than," and also as "greater than or equal to" and "greater than" (including "longer," "heavier," etc.). However, there is no substantial difference between "less than or equal to" and "less than," or between "greater than or equal to" and "greater."

[0013] Figure 1 illustrates an example of the correspondence between the communication device (IP phone 20) from a first perspective and the communication system 1 and IP phone system 2 according to the embodiment. The correspondence between the communication device (IP phone 20) from a first perspective and the communication system 1 and IP phone system 2, which will be described later with reference to Figure 2A and later, is as shown in Figure 1. In other words, as shown in Figure 1, the communication device (IP phone 20) from a first perspective is included in the IP phone system 2, and the IP phone system 2 is further included in the communication system 1.

[0014] Next, the configurations of communication system 1, IP phone system 2, and IP phone 20 will be described. Figure 2A is an example of one configuration of communication system 1 shown in Figure 1. Figure 2B is an example of one configuration of IP phone 20 shown in Figures 1 and 2A. As shown in Figure 2A, communication system 1 includes IP phone system 2 and a wide area network (WAN) 10 such as a VPN (Virtual Private Network) within a company. Note that if the wide area network 10 is unsuitable for ownership by an individual or organization such as a company, such as the Internet or a mobile phone network, communication system 1 does not need to include the wide area network 10.

[0015] The IP phone system 2 comprises IP phones 20-1 to 20-i to 20-n (where n is an integer greater than or equal to 2, and i is an integer from 1 to n), a wireless LAN access point (wireless LAN-AP) 24, and a configuration device 26. Communication between each of the IP phones 20-1 to 20-n and the wireless LAN access point 24 (wireless connection device) is established using communication establishment information such as the SSID (Service Set IDentifier) ​​and password (PW (Password)) of the wireless LAN access point 24, which conforms to wireless communication standards such as Wi-Fi (registered trademark), and can be conducted via wireless communication lines.

[0016] The configuration device 26 transmits communication establishment information to at least one of the IP telephones 20-1, 20-i, and 20-n via wireless or wired communication to configure them. The configuration device 26 and the IP telephones 20 may be connected via the wireless communication line used between the wireless LAN access point 24 and the IP telephones 20.

[0017] The wireless LAN access point 24 is, for example, a wireless router and is connected to the wide area network 10. The IP telephone 20 that has established communication with the wireless LAN access point 24 can transmit and receive digital-form information or analog-form signals to and from the wide area network 10 and other IP telephones 20 via the wireless LAN access point 24. That is, the IP telephones 20-1 to 20-i to 20-n and the wireless LAN access point 24 constitute a kind of wireless LAN. Further, at least two of the IP telephones 20-1 to 20-i to 20-n are connected via a radio wave signal that complies with a wireless communication standard such as Wi-Fi (registered trademark) or Bluetooth (registered trademark) and can transmit an audio signal modulated by digital-form information. That is, for example, between the IP telephones 20-i and 20-(i + 1) that are at least adjacent and are arranged at a short distance where the radio wave signal can reach, they are connected via the radio wave signal.

[0018] As shown in FIGS. 2A and 2B, the IP telephone 20 includes a receiver 202, an input device 204, an output device 206, a voice communication device 208, one or more processors 210, a main storage device 212, an auxiliary storage device 214, a voice processing device 216, and a wireless LAN interface (wireless LAN-IF (InterFace)) 218, which are housed in a housing 200 and are connected to each other so as to be able to mutually input and output information via a bus, signal lines, etc. That is, the IP telephone 20 includes components as a computer in addition to components as a telephone. In the IP telephone 20, an OS (Operating System; not shown) that mediates between the hardware of the IP telephone 20, such as Android (registered trademark), iOS (registered trademark), or TRON (The Real-time Operating system Nucleus), and the program executed in the IP telephone 20 is executed. Programs that execute various functions of the IP telephone 20 operate on the OS.

[0019] When the IP phones 20 are connected to each other via a wired communication line for calls (not shown), the IP phone 20 may further include a telephone communication line interface 220 (wireless communication line IF) as shown by the dotted line in FIG. 2B. The components of the IP phone 20 shown in FIGS. 2A and 2B are examples, and the IP phone 20 may further include other components.

[0020] The receiver 202, the input device 204, and the output device 206 are components used in a general digitally controlled telephone. The receiver 202 includes a microphone and a speaker, receives the user's voice through the microphone, outputs it as a voice signal to the voice processing device 216, and outputs the voice signal input from the voice processing device 216 to the user through the speaker. Note that the receiver 202 is also called a handset or the like.

[0021] Specifically, the input device 204 is a telephone keypad or the like, receives an operation by the user, and outputs information indicating the operation by the user to the processor 210. The output device 206 is, for example, a display device such as an LED (Light Emitting Diode) display device or an LCD (Liquid Crystal Display), displays the information input from the processor 210, and shows it to the user.

[0022] The voice communication device 208 receives a radio wave signal transmitted by another IP phone 20, demodulates the voice from the radio wave signal, and outputs the demodulated voice to the voice processing device 216. Also, the voice communication device 208 modulates a radio wave signal with the voice input from the voice processing device 216 and transmits the modulated radio wave signal to another IP phone 20. Note that the voice communication device 208 may be configured to receive a voice signal transmitted by another IP phone (by a microphone or the like), output the received voice signal to the voice processing device 216, and transmit the voice signal input from the voice processing device 216 to another IP phone 20 (by a speaker or the like).

[0023] The voice processing device 216 includes an analog-to-digital conversion circuit that converts voice signals into digital voice information, and a digital-to-analog conversion circuit that converts voice information into voice signals. The voice processing device 216 performs voice processing related to voice communication of the IP phone 20, detects information from voice signals received from other IP phones 20 and outputs it to the processor 210, and converts information such as communication establishment information input from the processor 210 into voice signals and outputs them to the voice communication device 208.

[0024] The wireless LAN interface 218 performs processing for transmitting and receiving information between the IP phone 20 and the wireless LAN access point 24 via a wireless communication line. The telephone communication line interface 220 performs processing for transmitting and receiving voice signals via a wired communication line for telephone calls.

[0025] The processor 210 includes one or more CPUs (Central Processing Units), or at least two combinations of one or more CPUs, one or more DSPs (Digital Signal Processors), and one or more GPUs (Graphics Processing Units). In the IP phone 20, one or more MPUs (Micro Processing Units) may be used instead of one or more CPUs. The processor 210 executes instructions contained in one or more programs stored in at least one of the main memory 212 and the auxiliary memory 214.

[0026] The main memory 212 includes, for example, one or more RAM (Random Access Memory) and one or more ROM (Read Only Memory) storage devices. The main memory 212 temporarily stores one or more programs that the IP phone 20 will run, as well as information and data required for the execution of those programs, in these storage devices.

[0027] The auxiliary storage device 214 includes, for example, a non-volatile computer-readable storage device such as an SSD (Solid State Drive) and flash memory, or one or more thereof. The auxiliary storage device 214 stores the program executed by the IP phone 20 and the information and data required for its execution for the medium to long term.

[0028] Furthermore, one or more programs stored in the main memory 212 of the IP phone 20 and executed by the processor 210 may be provided as a program product recorded on a non-transitory computer-readable storage medium. In addition to one or more programs, such a program product may include information and data that are essential for the execution of one or more programs.

[0029] Next, an overview of the operation of the IP phones 20 in the IP phone system 2 will be explained. Figure 3 is a diagram illustrating an overview of one operation of IP phones 20-1, 20-i, and 20-n shown in Figures 1, 2A, and 2B. As shown in Figure 3, for example, the configuration device 26 transmits communication establishment information (SSID, PW) to IP phones 20-1, 20-2, and 20-3, which are installed within range #1 of the radio signal from IP phone 20-1, with a radius r (m). IP phones 20-1, 20-2, and 20-3 receive the communication establishment information from the configuration device 26. IP phones 20-1, 20-2, and 20-3 transmit the received communication establishment information to the wireless LAN access point 24, establishing communication between IP phone 20-1 and the wireless LAN access point 24.

[0030] As explained above, the setting device 26 sets communication establishment information for one or more of the IP phones 20-1 to 20-i to 20-n, either by the setting device 26 or via the input device 204 of the IP phone 20. In this way, the communication establishment information set for one or more of the IP phones 20-1 to 20-i to 20-n is automatically set sequentially for all of the IP phones 20-1 to 20-i to 20-n.

[0031] IP phones 20-4 and 20-i, located in range #2 with a radius r(m) adjacent to range #1, transmit a radio signal modulated with a voice communication establishment information request to another IP phone 20 (e.g., IP phone 20-3) at predetermined timings, for example, at predetermined times or at predetermined intervals. IP phone 20-3 receives this communication establishment information request. In response to the received communication establishment information request, IP phone 20-3 transmits a radio signal modulated with voice communication establishment information to IP phones 20-4 and 20-i. IP phones 20-4 and 20-i receive voice communication establishment information from IP phone 20-3. Furthermore, IP phones 20-4 and 20-i demodulate the communication establishment information from the received voice communication establishment information and transmit it to the wireless LAN access point 24, establishing communication between IP phones 20-4 and 20-i and the wireless LAN access point 24. Furthermore, voice communication establishment information and communication establishment information requests can be obtained, for example, by converting the carrier wave of the voice frequency band to DTMF (Dual Tone Multi Frequency) or by modulating it using PSK or QPSK (Quadrature Phase Shift Keying) based on digital communication establishment information and communication establishment information requests.

[0032] Furthermore, similarly, IP phones 20-(n-1) and 20-n installed in range #3 with a radius r(m) adjacent to range #2 transmit a radio signal modulated by a voice communication establishment information request to another IP phone 20 (for example, IP phone 20-i) at a predetermined timing. IP phone 20-3 receives this communication establishment information request. IP phone 20-i receives this communication establishment information request. In response to the received communication establishment information request, IP phone 20-i transmits communication establishment information to IP phones 20-(n-1) and 20-n. IP phones 20-(n-1) and 20-n receive the communication establishment information from IP phone 20-i. Furthermore, IP phones 20-(n-1) and 20-n transmit the received communication establishment information to the wireless LAN access point 24, establishing communication between IP phones 20-(n-1) and 20-n and the wireless LAN access point 24.

[0033] Next, the processing of the IP phone system 2 and the IP phone 20 will be described in detail. For the purpose of making the explanation more concrete and clear, the following explanation will use the example of a case where the IP phone 20 and the wireless LAN access point 24 are connected via a wireless communication line compliant with the Wi-Fi (registered trademark) standard, and the SSID and its password are used as communication establishment information. Furthermore, the explanation of the call functions of the IP phone system 2 and the IP phone 20 will be omitted in the following explanation.

[0034] Figure 4 is a flowchart illustrating an example of the communication establishment process S10 of the IP telephone 20 shown in Figures 1, 2A, and 2B. Figure 5 is a communication sequence diagram illustrating the SSID and PW (communication establishment information) setting process S20 between IP telephones 20 in the IP telephone system 2. For illustrative purposes, Figure 5 shows a specific example of the communication sequence between the wireless LAN access point 24, the configuration device 26, and IP telephones 20-1, 20-i, and 20-n. Each of the processes shown in Figures 4 and 5 may also be called a step or process.

[0035] As shown in Figure 4, in S100, the IP phone 20 starts up in response to the user powering it on. In S102, the processor 210 of the IP phone 20 (Figure 2B) determines whether the SSID and PW of the wireless LAN access point 24 have been stored in the auxiliary storage device 214 by the setting device 26 or by user operation and have been set on the IP phone 20. If the SSID and PW have been set (Y in the process of S102), the processor 210 proceeds to the process of S104; otherwise, it proceeds to the process of S120.

[0036] In S104, the processor 210 transmits the configured SSID and PW from the wireless LAN interface 218 to the wireless LAN access point 24, establishing communication between the IP phone 20 and the wireless LAN access point 24. In S106, the processor 210 controls each component of the IP phone 20 and starts processing it as an IP phone to communicate digital information and voice with other IP phones 20 via the wireless communication line with the wireless LAN access point 24.

[0037] In S108, the processor 210 determines whether it has received a request to set a voice SSID and PW (communication establishment information request) from another IP phone 20 via radio signals through the voice communication device 208 and the voice processing device 216. If the processor 210 has received a request to set a voice SSID and PW from another IP phone 20 (Y in the process of S108), it proceeds to the process of S110; otherwise, it proceeds to the process of S112. In S110, the processor 210 transmits the voice SSID and PW to the other IP phone 20 via the voice communication device 208 and the voice processing device 216 in response to the SSID and PW setting request.

[0038] In S120, the processor 210 determines whether the SSID and PW have been set by the setting device 26. If the SSID and PW have been set (Y in the process of S120), the processor 210 proceeds to the process of S122; otherwise, it proceeds to the process of S140. In S122, the processor 210 receives the digital SSID and PW obtained by demodulating the voice SSID and PW using the voice processing device 216. In S124, the processor 210 stores the received SSID and PW in, for example, the auxiliary storage device 214.

[0039] In S140, the processor 210 uses the timer circuit (not shown) of the IP phone 20 to determine whether the time at which this process is performed is the time when a radio signal for requesting the setting of the voice SSID and PW can be sent to another IP phone 20. If it is the time to send the radio signal for requesting the setting of the voice SSID and PW to another IP phone 20 (Y in the process of S140), the processor 210 proceeds to the process of S142; otherwise, it returns to the process of S120.

[0040] In S142, the processor 210 generates a voice SSID and PW setting request using the voice communication device 208 and the voice processing device 216, and transmits it as a radio signal to the other IP phone 20 from the voice communication device 208. In S144, the processor 210 determines whether or not it has received the voice SSID and PW from the other IP phone 20 via the voice communication device 208 and the voice processing device 216. If the processor 210 has received the voice SSID and PW (Y in the process of S144), it proceeds to the process of S124; otherwise, it returns to the process of S120. As each of the IP phones 20-1, 20-i, and 20-n performs the process described above, the SSID and PW set on any of them are sequentially set on all of the IP phones 20-1, 20-i, and 20-n.

[0041] Furthermore, as shown in Figure 5, in S200, the setting device 26 sets the SSID and PW on the IP phone 20-1. In S202, the processor 210 of the IP phone 20-1 sets the configured SSID and PW on the IP phone 20-1 by storing them in the auxiliary storage device 214. In S204, the processor 210 of the IP phone 20-1 transmits the configured SSID and PW from the wireless LAN interface 218 to the wireless LAN access point 24, establishing communication between the IP phone 20-1 and the wireless LAN access point 24.

[0042] When it is time to request the setting of the SSID and PW, in S210, IP phone 20-i transmits a voice SSID and PW setting request to another IP phone 20 (IP phone 20-1) via radio signal. In S212, upon receiving the voice SSID and PW setting request radio signal from IP phone 20-i, IP phone 20-1 transmits the voice SSID and PW radio signal to the other IP phone 20 (IP phone 20-i). In S214, IP phone 20-i receives the voice SSID and PW radio signal from IP phone 20-1 and sets the SSID and PW by storing the demodulated SSID and PW from the radio signal. In S216, IP phone 20-i transmits the set SSID and PW to the wireless LAN access point 24, establishing communication between the wireless LAN access point 24 and IP phone 20-i.

[0043] When it is time for SSID and PW setting requests to be made, in S220, IP phone 20-n sends a voice SSID and PW setting request to another IP phone 20 (IP phone 20-i) via radio signal. In S222, upon receiving the voice SSID and PW setting request radio signal from IP phone 20-n, IP phone 20-i sends the voice SSID and PW radio signal to the other IP phone 20 (IP phone 20-n). In S224, IP phone 20-n receives the voice SSID and PW radio signal from IP phone 20-i and sets the SSID and PW by storing the demodulated SSID and PW from the radio signal. In S226, IP phone 20-n sends the set SSID and PW to the wireless LAN access point 24, establishing communication between the wireless LAN access point 24 and IP phone 20-n.

[0044] Most IoT (Internet of Things) devices, including IP phones, access wide-area networks such as the internet via Wi-Fi. However, there are various methods for configuring Wi-Fi connections depending on the type of IoT device. One example of such a method is to temporarily establish a network compliant with the Bluetooth® standard between the IoT device and a device such as a smartphone to configure the Wi-Fi connection. The Wi-Fi Easy Connect standard has also been developed for this purpose. Furthermore, when IoT devices are equipped with input and output devices, system administrators may have to manually configure the Wi-Fi connection for each of the numerous IoT devices. When IP phones are used as IoT devices, the number of devices can reach tens to hundreds, so configuring the Wi-Fi connection for each device places a heavy burden on system administrators and requires a long amount of work time. The IP phone described above reduces the burden and work time for system administrators when configuring Wi-Fi connections for many IoT devices.

[0045] Some or all of the above embodiments may also be described as follows, but are not limited to the following: [Note 1] (See Perspective 1 of the above disclosure) [Note 2] The voice communication device, except when it is receiving the communication establishment information via the first wireless communication line or the second wireless communication line, transmits a request to transmit the communication establishment information by voice, as described in Appendix 1.
