Description

  The present invention relates to a communication system.

  In recent years, mobile phones have become widespread and are used by many people. As for mobile phones, infrastructure development by mobile phone operators is progressing, and calls can be made everywhere. However, it is not suitable for frequent contact because of the cost of call charges. Also, especially when considering use in automobiles, the operation of mobile phones is dangerous while driving and is a violation in Japan. When a mobile phone is used during operation, for example, as disclosed in Patent Documents 1 and 2, a device having a hands-free function or the like is separately required.

  On the other hand, a wireless device representative for business use often does not incur a call charge and is very convenient for business communication, but has a limited call area and often lacks infrastructure.

Therefore, for example, a truck driver of a transportation company makes communication on a business basis with a wireless device, but most of them have a mobile phone at the same time, and two devices are used as communication means.

However, when two communication devices are used as described above, the following points are inconvenient.
・ Even if the purpose (call or data communication) was the same, it was necessary to operate the terminals used separately.
・ Even if you want to talk to the same party, if the other party is using a telephone and a radio, the other party's data (phone number, etc.) must be managed separately for each device.
-When either device was out of service area, the operator had to check the status and select the device.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a communication system that improves usability when using two communication devices, a wireless device and a mobile phone.

  The communication system of the present invention connects a wireless device and a mobile phone, and the wireless device can be used as a hands-free device for the mobile phone and can also communicate with the wireless device alone. A connector and a connection protocol adapted to the external connection interface of the telephone are installed, and the wireless device and the mobile phone are connected by wire or wireless.

In the communication system of the present invention as described above, a more specific example can be as follows.

  According to the communication system of the present invention as described above, it is only necessary to operate the wireless device regardless of whether the communication is performed using the mobile phone or the wireless device. improves.

  Embodiments of a communication system according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention, in which 10 is a mobile phone, and 20 is, for example, a business radio. The radio device 20 has a speaker 21 on the upper surface of the main body, an operation unit 22 and a display unit 23 on the front surface of the main body, and a microphone with a PTT switch 26 via a connector 24 and a cable 25 on the front surface of the main body. 27 is connected.

  Furthermore, the radio device 20 is equipped with a connector and a connection protocol (not shown) that match the external connection interface of the mobile phone 10. Therefore, the connector 20 and the external connection terminal 11 of the mobile phone 10 are connected by the interconnection cable 30 for serial communication, and the mobile phone 10 is connected to the radio device 20, whereby the radio device 20 is connected to the handset of the mobile phone 10. It can be used as a free device, and communication (data communication and voice call) with the mobile phone 10 can be performed by operating the radio device 20. Of course, even in such a connected state, the wireless device 20 can communicate with the wireless device alone.

  Therefore, when the mobile phone 10 receives an incoming call, a ring tone sounds from the speaker 21 of the wireless device 20. When responding, the user presses the PTT switch 26 attached to the microphone 27 of the wireless device 20. As a result, the mobile phone 10 enters an off-hook state and can talk. The telephone call is performed using the microphone 27 and the speaker 21 of the wireless device 20. At this time, it is not necessary to press the PTT switch 26 for each transmission as in a normal radio. After the call, when the call ends, the PTT switch 26 is pressed and held. Then, the wireless device 20 detects the end-of-call operation and disconnects the mobile phone 10.

  On the other hand, when there is an incoming call to the radio device 20, it is the same as the conventional method of use, and a call is made using the microphone 27, PTT switch 26 and speaker 21 of the radio device 20.

  On the other hand, the transmission is performed by depressing the PTT switch 26 of the wireless device 20. At this time, as to a transmission method of using the mobile phone 10 or the wireless device 20 to transmit, (1) Automatic A method of making a call by selection, (2) a method of making a call by designating the mobile phone 10 as a device for sending, and (3) a method of making a call by designating the radio device 20 as a device for making a call. The information is registered in the device 20, and at the time of making a call, which transmission method is used is selected by the operation unit 22 of the wireless device 20.

  The automatic transmission method of (1) is based on the S meter value of the wireless device 20 and the RSSI value (received radio wave state) of the mobile phone 10, which of the wireless device 20 and the mobile phone 10 has a communication state. Judge whether it is good, select the device with the better communication state, and make a call. When the communication state is the same, a call is made using a priority device registered in advance in the wireless device 20. In that case, it is necessary to designate the other party's telephone number for the mobile phone 10. In the wireless device 20 according to the present embodiment, the mobile phone 10 is accessed to acquire the phone book information of the mobile phone 10 and can be browsed on the display unit 23. Further, the radio phone 20 can be selected from the browsed phone book information. Can be selected by the operation unit 22. Then, the selection information is transmitted from the wireless device 20 to the mobile phone 10, and the mobile phone 10 also selects a desired call partner from the phone book information and designates the phone number of the call partner as the mobile phone 10.

  FIG. 2 shows an operation flowchart in the case of making a call by automatic selection. First, when the PTT switch 26 of the wireless device 20 is pressed in step S1, the wireless device 20 confirms the communication state of both devices (the mobile phone 10 and the wireless device 20) (step S2). Next, the process proceeds to step S3, and it is determined from the communication state whether both devices can be used. If there is only one device that can be used, the process proceeds to step S4, and the message is transmitted from the device that can be used. For example, when it is determined in step S3 that the radio wave condition of the radio device 20 is poor and the radio device 20 cannot be used, the mobile phone 10 is selected in step S4 and transmitted by the mobile phone 10.

  On the other hand, if it is determined in step S3 that both devices can be used, the priority device registered in advance in the wireless device 20 is used for transmission. For example, if the wireless device 20 is registered as a priority device, the wireless device 20 is used for transmission. Then, when the other party responds after being transmitted by the mobile phone 10 or the wireless device 20 in this way, the speaker 21 and the microphone 27 of the wireless device 20 are connected regardless of the transmission by the mobile phone 10 or the wireless device 20. Use to make a call. Further, in the case of a call using the mobile phone 10, the call is ended using the PTT switch 26 of the radio device 20.

  In the case of a mobile phone, the communication state can always be determined from the RSSI value. However, in the case of a wireless device, when the PTT switch 26 is pressed, radio waves from the other station are captured in a timely manner and the other station can be determined from the value of the S meter. Since it is difficult to determine the communication state of the other station, it is preferable to receive the radio wave of the other station before the time of transmission and store it while sequentially updating the communication state with the other station. When the PTT switch 26 is pressed, it is preferable to determine the communication state from the latest communication state stored (the value of the S meter and the received radio wave state). Here, it is more preferable to determine the communication status by capturing the radio waves of the partner station that actually communicates. However, is it possible to communicate with this radio even if the communication status is determined by capturing the radio waves of other stations on the same channel? It's okay if it's a rough idea.

  The method of making a call by designating the mobile phone 10 as a calling device in (2) is used when the other party can receive a call only by phone. When the PTT switch 26 of the radio 20 is pressed, the mobile phone 10 Make outgoing calls. Also at this time, the telephone number of the other party is designated to the mobile phone 10 by the wireless device 20 as in the case of the automatic selection of (1). Further, the telephone call and the end call after the other party answers are performed using the speaker 21, the microphone 27, and the PTT switch 26 of the radio device 20, as in the case of (1).

  In the method (2), when the mobile phone 10 is out of service area or cannot be used due to extremely poor radio wave environment, the radio device 20 is equipped with a PSTN connection function, and the radio device 20 is connected to a general telephone line. By doing so, it is possible to make a call via a general telephone line. However, this method can be used only in an environment where the wireless device 20 can be connected to a general telephone line such as in a company. Also, since the wireless device 20 is owned by the company and private use is prohibited, and depending on the other party, it is assumed that wireless communication is not possible. Can be selected. For example, in the method (1), even if the phone number is specified and the mobile phone 10 is supposed to make a call, depending on the RSSI value of the mobile phone 10, the radio is transmitted. If it is determined that the specific partner is selected in (2), the method (2) is forcibly selected.

  The method of transmitting by specifying the wireless device 20 as a transmission device in (3) is used when the other party can receive a call only with the wireless device. When the PTT switch 26 of the wireless device 20 is pressed, the wireless device 20 is used. Makes outgoing calls. Of course, the call after the other party answers is performed using the speaker 21 and the microphone 27 of the wireless device 20.

And according to the above communication systems, the following effects can be acquired.
In both cases of communication using the mobile phone 10 and communication using the wireless device 20, only the wireless device 20 needs to be operated, so that the usability when using two communication devices is improved. Moreover, since it becomes hands-free by radio | wireless machine operation, the safety | security on driving | running can be ensured.
-The phone book information of the mobile phone 10 can be acquired and viewed by the radio device 20 and the phone book information only needs to be managed on the mobile phone side, so that the phone book information can be easily managed.
-If automatic selection is used at the time of transmission, the user does not select a device according to the communication state, and the mobile phone 10 is used in an area where the wireless device cannot be used, and the wireless device 20 is used where the wireless device can be used. Thus, reliable communication can be performed at low cost.
-In addition to automatic selection, by specifying the mobile phone 10 or the radio device 20 as a transmission device and enabling transmission, it is also possible to select an optimal communication device according to the purpose with the intention of the user it can.
-If the mobile phone transmission is forcibly selected by the other party, it is possible to prevent the other party who cannot make a call with the wireless device from making an erroneous transmission with the wireless device.

The communication system as described above can be further performed as follows.
When the mobile phone 10 and the wireless device 20 are connected, the wireless device 20 acquires the identification information from the mobile phone 10 and compares it with the identification information stored in the wireless device 20 itself. If it is determined to be a telephone, a connection is established.
In the embodiment, the cable is assumed to be serial communication for connection, but can be USB connection or the like. Furthermore, not only wired but also wireless connection such as Bluetooth and ZigBee can be used.
The telephone directory information of the mobile phone 10 is edited using the operation unit 22 while acquiring and browsing the phone book information with the radio device 20, and the edited information is transmitted from the radio device 20 to the mobile phone 10. Information can be changed.
・ Since mobile phone charges change depending on the time of day for mobile phones of recent times, in the automatic selection of (1), time information is acquired from the clock mounted on the radio device 20 or the mobile phone 10 and the priority device is selected according to the time. Switching between the radio device 20 and the mobile phone 10 is performed.
Since the display of the recent mobile phone is excellent, the mobile phone 10 can acquire and view information on the wireless device 20 and the setting of the wireless device 20 can be changed on the mobile phone 10.
