As described above, for example, in a PHS wireless communication system for offices, when there are a large number of PHS telephones in the same wireless area, it is not possible to cause some PHS telephones to receive broadcast audio. There is a problem, and in particular, when an important message is transmitted by simultaneous broadcasting, there is a request to notify all PHS telephones of it.
The present invention has been made in view of such a conventional situation, and exceeds the number capable of wireless communication with a base station apparatus (for example, the PHS base station apparatus in the above example). Provided is a wireless communication system capable of notifying all terminal devices of broadcast information transmitted wirelessly from a base station device even when a terminal device (for example, a PHS telephone in the above example) exists. The purpose is to do.

In order to achieve the above object, in the wireless communication system according to the present invention, the base station apparatus and the terminal apparatus are wirelessly connected by the first communication method and configured to perform wireless communication using the first communication method as follows. Broadcast information is transmitted to the terminal device via the base station device.
That is, in the base station apparatus, the broadcast receiving means receives the broadcast information transmitted from the broadcast transmitting apparatus, and the broadcast transmission means is wirelessly connected to the base station apparatus (self apparatus). The broadcast information received by the broadcast receiving means is wirelessly transmitted to the terminal device.
In the terminal device, when wirelessly connected to the base station device, the information receiving unit receives the information on the broadcast broadcast wirelessly transmitted from the base station device. In addition, the second wireless transmission unit wirelessly transmits information corresponding to the broadcast information received by the information reception unit using a second communication method different from the first communication method.
Further, in the terminal device, when the wireless connection with the base station device is not connected, the second wireless receiving means is wirelessly transmitted from another terminal device using the second communication method. Receive information corresponding to broadcast information.
In the terminal device, when the reproducing unit receives the broadcast information by the information receiving unit, the reproducing unit reproduces the information, or responds to the broadcast information by the second wireless receiving unit. When information is received, the information is reproduced.

Therefore, a terminal device that wirelessly connects to the base station device and receives broadcast information transmits the information corresponding to the information wirelessly using a different communication method, and a terminal device that cannot wirelessly connect to the base station device performs the different communication. By receiving the information in a manner, for example, even when there are more terminal devices than can be wirelessly communicated with the base station device, wireless transmission is performed from the base station device. Broadcast information (including corresponding information) can be notified to all terminal devices.
As one configuration example, the present invention can be applied to a PHS radio communication system. In this case, the base station apparatus is configured by a PHS base station apparatus, the terminal apparatus is configured by a PHS terminal apparatus, and the first communication method is PHS. It is a communication method.

Here, as the broadcast transmission device, various devices that transmit (send) broadcast information may be used. For example, any terminal device may be used, or broadcast information may be transmitted. Some terminal devices to which the authority to make a call is given may be used, or devices other than the terminal device may be used.
Also, broadcast information transmitted from the broadcast transmission device may be received by the base station device via, for example, a control device.
As broadcast information, for example, various information such as audio information, text information, and image information may be used.
Various communication methods may be used as the first communication method and the second communication method, respectively. For example, a communication system of various wireless communication systems such as PHS is used as the first communication system, and a communication system such as weak wireless or Bluetooth can be used as the second communication system.

In addition, the process in which the terminal device wirelessly transmits information corresponding to broadcast information using the second communication method is executed only when there is an instruction from a higher-level device such as a control device. Such a mode may be used, or a mode that is always executed every time broadcast information is received may be used.
Further, as the information corresponding to the broadcast information that the terminal device wirelessly transmits using the second communication method, for example, the same information as the broadcast information may be used, or the information may not be exactly the same. Information having similar contents may be used.
In addition, as a mode for reproducing information, for example, a mode in which sound based on voice information is output from a speaker, a mode in which characters based on character information are displayed on the screen, or an image based on image information is displayed on the screen The mode to perform etc. can be used.

  As described above, according to the wireless communication system according to the present invention, the base station device and the terminal device are wirelessly connected to perform wireless communication by the first communication method, and the terminal is transmitted from the simultaneous broadcast transmission device via the base station device. When transmitting broadcast information to a device, a terminal device wirelessly connected to the base station device wirelessly transmits information corresponding to the broadcast information received from the base station device using the second communication method. Since the terminal device that could not be wirelessly connected to the station device received information corresponding to the broadcast information wirelessly transmitted from the other terminal device using the second communication method, for example, the base station device Even when there are more terminal devices than can perform wireless communication between them, broadcast terminal information (including corresponding information) wirelessly transmitted from the base station device is transmitted to all terminals. It can be notified to the location.

Embodiments according to the present invention will be described with reference to the drawings.

In this example, one PHS base station apparatus 2 can wirelessly connect to up to three PHS telephones.
Further, in the wireless communication system of the present example, it is possible to broadcast simultaneously to the PHS telephones A1 to A6 and the wired telephone 3 existing under the system, for example, a device that transmits information on the simultaneous broadcasting It is possible to notify the same information simultaneously (or almost simultaneously) to all the telephones existing under the system from the (broadcasting broadcasting device).
In this example, audio information is used as broadcast information, but various information such as text information and image information may be used.

First, with reference to FIG. 1, the outline | summary of the characteristic which the radio | wireless communications system of this example has is demonstrated.
For example, when the same message information is wirelessly transmitted from the PHS base station apparatus 2 to a plurality of PHS telephones by simultaneous broadcasting, the three PHS telephones A1 to A3 are wirelessly connected to the PHS base station apparatus 2. The message information can be received, but the other three PHS telephones A4 to A6 cannot wirelessly connect to the PHS base station apparatus 2 and cannot receive the message.
Therefore, in this example, the PHS base station transmits the message information received by the PHS telephone (for example, PHS telephone A3) that has received the message information from the PHS base station apparatus 2 by using a weak radio or Bluetooth. The message information is also notified to the PHS telephones A4 to A6 that cannot be wirelessly connected to the apparatus 2. Thereby, even in the PHS telephones A4 to A6 that cannot be wirelessly connected to the PHS base station apparatus 2, the same broadcast message information that is wirelessly transmitted from the PHS base station apparatus 2 can be received. The user (person) can hear the voice of the message information.

Next, it explains in detail.
FIG. 2 shows a hardware configuration example of the PHS telephone set A. In this example, the configurations of the PHS telephones A1 to A6 are the same, and these are collectively shown as the PHS telephone A.
The PHS telephone A of this example includes a PHS radio 11 having a transmitter 21, a receiver 22, and an antenna 23, a weak radio 12 having a transmitter 31, a receiver 32, and an antenna 33, a distributor 13, The transmission path switch 14, the reception path switch 15, the receiver 16, the transmitter 17, and the internal memory 18 are provided.
Here, the PHS wireless device 11 has a function of performing wireless communication by a PHS communication method, and the weak wireless device 12 has a function of performing wireless communication by a weak wireless (such as Bluetooth) communication method. is doing.

In the PHS telephone A, a voice such as a user's voice is input by the transmitter 17, and the information of the voice is transmitted by the transmission unit 21 of the PHS radio 11 and wirelessly transmitted from the antenna 23.
In addition, a signal wirelessly received by the antenna 23 of the PHS radio 11 is subjected to reception processing by the receiving unit 22 and distributed to two signals by the distributor 13. A transmission path switch 14 and a reception path switch 15 are connected to the distributor 13.
The transmission path switch 14 has a function of switching the connection state between the distributor 13 and the transmission unit 31 of the weak wireless device 12 between on (connected) and off (not connected). In a state in which the transmission path switch 14 is on, information received by the reception unit 22 of the PHS radio 11 is input to the transmission unit 31 of the weak radio 12 via the distributor 13 and the transmission path switch 14. Then, transmission processing is performed by the transmission unit 31 and wireless transmission is performed from the antenna 33.

A signal wirelessly received by the antenna 33 of the weak wireless device 12 is received by the receiving unit 32.
The receiving path switch 15 has a function of switching between a state in which the distributor 13 and the receiver 16 are connected and a state in which the receiving unit 32 of the weak radio 12 and the receiver 16 are connected.

In a state where the reception path switch 15 connects the distributor 13 and the receiver 16, information received by the receiving unit 22 of the PHS radio 11 is input to the receiver 16 via the distributor 13 and the reception path switch 15. The sound as the information is output to the user.
Further, when the reception path switch 15 connects the reception unit 32 of the weak wireless device 12 and the receiver 16, information received by the reception unit 32 of the weak wireless device 12 is input to the receiver 16 via the reception path switch 15. For example, the voice as the information is output to the user.

FIG. 3 shows an example of information stored in the internal memory 18 of the PHS telephone A.
The internal memory 18 stores preset broadcast special information and broadcast special response information in advance.
The broadcast special number information is information on a special telephone number assigned to the broadcast, and is used in the broadcast from the PHS base station apparatus 2 side to the PHS telephone A side. The broadcast special response number information is information on a special telephone number for responding when a broadcast is received, and is for broadcast from the PHS telephone A side to the PHS base station apparatus 2 side. Used in response.

FIG. 4 shows an example of the weak radio frequency allocation table 41 stored in the internal memory of the PHS control device 1.
In the weak radio frequency allocation table 41, number information (PHS base station No.) that is information for identifying the PHS base station apparatus 2 and information on the frequency allocated to the weak radio (weak radio allocation frequency) are stored in advance. Correspondence is set and stored.
The PHS controller 1 designates a radio channel (frequency in this example) to be used for weak radio in units of each PHS base station apparatus 2 based on the contents of the weak radio frequency allocation table 41. In this example, a different channel number (ch number) is assigned to each radio channel.
Here, in this example, only one PHS base station apparatus 2 is shown, but normally, a plurality of PHS base station apparatuses are provided, and in this case, the communication area of each PHS base station apparatus The frequency of the weak radio used in can be distributed.

Next, an example of the operation performed in the wireless communication system of this example is shown.
Referring to FIG. 5, an example of an operation sequence when PHS telephone A is waiting is shown.
When receiving a broadcast request from a broadcast transmission device (for example, the wired telephone 3 or the PHS telephone A), the PHS control device 1 displays incoming call information (including a broadcast broadcast special number) corresponding to the broadcast. Transmit to the base station apparatus 2. When the PHS base station device 2 receives incoming information (including a broadcast special number) corresponding to the broadcast from the PHS control device 1, the PHS base station device 2 wirelessly transmits the incoming information to the PHS telephone A using the broadcast special number. Send. In addition, as a PHS telephone set that can make a broadcast request, for example, a configuration in which only some authorized PHS telephones are used may be used.
When receiving the incoming information from the PHS base station apparatus 2, the PHS telephone A confirms the contents of the incoming information, and if the incoming call is a broadcast special number, the PHS base station apparatus uses the broadcast response special number. 2 is transmitted wirelessly.

Specifically, when receiving the incoming call information, the PHS telephone set A compares the telephone number stored in the incoming call information with the broadcast broadcast special number preset in the internal memory 18, When the numbers match, it is recognized that the broadcast is simultaneous.
In this example, the PHS telephone A automatically responds to the broadcast, and in this automatic response, the PHS base station apparatus responds with the broadcast special response number registered in the internal memory 18 in advance. 2 starts connection with the PHS control device 1.

When receiving a call from the PHS telephone A, the PHS base station apparatus 2 transmits the call to the PHS control apparatus 1 correspondingly. When receiving a call from the PHS base station apparatus 2, the PHS control apparatus 1 transmits a response to the PHS base station apparatus 2 accordingly. When receiving a response from the PHS control device 1, the PHS base station device 2 wirelessly transmits a response corresponding to the response to the PHS telephone A. Then, when the PHS telephone set A receives the response from the PHS base station apparatus 2, the connection is completed.
Here, when the PHS telephone set A can connect to the PHS control apparatus 1 via the PHS base station apparatus 2 at the time of the response, the contents of the simultaneous broadcast received from the PHS base station apparatus 2 (this book) In the example, voice) is sent to the receiver 16. In this case, in the PHS telephone A, the distributor 13 and the receiver 16 are connected by the receiving path switch 15.

After the above connection is completed, the PHS control device 1 transmits, for each PHS base station device 2, additional information indicating a frequency used for weak radio to a predetermined PHS telephone. In this example, this additional information is sent for each PHS base station apparatus 2 to the PHS telephone that is initially connected. When the PHS base station apparatus 2 receives the additional information from the PHS control apparatus 1, the PHS base station apparatus 2 transmits the additional information to the PHS telephone A (in this example, the PHS telephone that is first connected to the PHS base station apparatus 2). Wirelessly transmit.
When the PHS telephone set first connected to the PHS base station apparatus 2 receives additional information from the PHS base station apparatus 2, the PHS telephone uses the frequency indicated by the additional information to receive from the PHS base station apparatus 2. The broadcast information (sound in this example) is wirelessly transmitted by weak radio. In this case, in the PHS telephone, the distributor 13 and the transmission unit 31 of the weak radio 12 are connected by the transmission path switch 14.

As described above, in this example, after the connection is completed, the PHS control device 1 instructs the PHS telephone A whether or not to perform transmission to the weak radio 12 by additional information, and at the same time, the weak radio 12 The transmission frequency to be used is designated by a channel number, for example. As additional information, for example, in the signal information element on the PHS protocol, there are items of designation of presence / absence of wireless transmission (in this example, transmission by weak wireless) and channel designation (in this example, designation of a wireless channel). Use the one with added. Further, the additional information may include, for example, information indicating whether or not transmission to the weak radio 12 is performed, or an instruction to transmit to the weak radio 12 when the additional information is received. It is also possible to adopt a configuration that recognizes that
Further, in this example, in the PHS telephone that is first connected to the PHS base station apparatus 2, the voice is distributed so that the voice distributed by the distributor 13 is transmitted from the weak radio 12 mounted on the PHS telephone. The distributor 13 and the transmitter 31 of the weak radio 12 are connected by the path switch 14. The receiving path switch 15 is connected to the PHS radio 11 side, that is, the distributor 13 and the receiver 16 are connected.

  Note that, as an aspect of determining a PHS telephone set that has completed connection to the PHS base station apparatus 2 first, for example, the PHS telephone set is notified from each PHS telephone to the PHS control apparatus 1 via the PHS base station apparatus 2. Use a mode in which the control device 1 decides or a mode in which the PHS phone that the PHS control device 1 first sent a connection response is regarded as a PHS phone that was first switched to a broadcast state. Can do.

In the PHS telephone that cannot be connected to the PHS control apparatus 1 via the PHS base station apparatus 2 at the time of response, the reception path switch 15 is connected to the weak radio 12 side, that is, the weak radio. The receiver 32 and the receiver 16 of the mobile device 12 are connected, and the wireless channel (frequency in this example) used by the weak wireless device 12 of the PHS telephone that is initially connected to the PHS base station device 2 is searched. Thus, the voice received by the receiving unit 32 of the weak radio 12 can be heard by the receiver 16.
In the PHS telephone A of this example, when broadcast is performed, for example, only reception is performed and transmission is not performed. The communication is disconnected by pressing the on-hook button of the PHS telephone A.

Referring to FIG. 6, an example of an operation sequence when PHS telephone A is communicating is shown.
The PHS control device 1 transmits additional information to the PHS base station device 2 when receiving a broadcast request from a broadcast transmission device (for example, the wired telephone 3 or the PHS telephone A). When the PHS base station apparatus 2 receives the additional information from the PHS control apparatus 1, the PHS base station apparatus 2 wirelessly transmits the additional information to the PHS telephone set A.
As described above, when the PHS telephone A is in a call state other than the broadcast, the call path (voice line) is forcibly switched to the broadcast line in the PHS control apparatus 1 and the call is automatically made. PHS phone A will enter the broadcast. At this time, the PHS control device 1 notifies the PHS telephone set A whether or not to perform transmission to the weak radio 12 and also notifies additional information indicating the frequency to be used in the weak radio.

In this example, as the PHS telephone set A that notifies the additional information, for each PHS base station apparatus 2, the PHS telephone set A entered the broadcasting first from the wirelessly connected PHS telephone sets A (switched to the broadcasting state first). E) A PHS telephone.
When the PHS telephone that is first switched to the broadcast state receives additional information from the PHS base station apparatus 2, the PHS telephone using the frequency indicated by the additional information uses the simultaneous broadcast received from the PHS base station apparatus 2. Broadcast information (sound in this example) is wirelessly transmitted by weak radio. Specifically, when this PHS telephone receives additional information, the transmission path switch 14 is turned on to send a broadcast sound from the PHS radio 11 side to the weak radio 12 side. 12 starts transmission of radio waves by switching on the transmission path switch 14 and specifying a transmission channel (in this example, frequency).

  As an aspect of determining the PHS phone that has been switched to the broadcast state first, for example, the PHS control device 1 is notified from each PHS phone via the PHS base station device 2 that the PHS phone has been switched to the broadcast state. A mode in which the PHS control device 1 determines, or a mode in which the PHS control device 1 first determines that the PHS phone that is first instructed to switch to the broadcast is a PHS phone that has been switched to the broadcast state first. Can be used.

  Here, in this example, the PHS control device 1 uses the transmission channel used by the weak radio 12 so that the use frequency of the weak radio is distributed in units of the PHS base station device 2 to which the PHS telephone A is connected. (In this example, frequency) is specified. For this reason, as in the weak radio frequency allocation table 41 shown in FIG. 4, weak radio frequency allocation is set in advance for each PHS base station apparatus 2 in the PHS control apparatus 1. The PHS control device 1 instructs the PHS telephone A about the frequency to be used in the weak radio based on the information in the weak radio frequency allocation table 41.

  Further, for example, when both a standby PHS telephone as shown in FIG. 5 and a PHS telephone in communication as shown in FIG. 6 exist, for example, the PHS telephone (FIG. 5)), a mode in which weak wireless communication is performed, or a mode in which weak wireless communication is performed by a PHS telephone (in the case of FIG. 6) that is first switched to a broadcast state, or both A mode in which weak wireless communication is executed by an earlier PHS telephone can be used.

As a specific example, in the wireless communication system shown in FIG. 1, three PHS telephones A1 to A3 out of six PHS telephones A1 to A6 can be wirelessly connected to the PHS base station apparatus 2, one of which The weak PHS telephone A3 completes connection with the PHS base station apparatus 2 first (in the case of FIG. 5) or first switches to the state of simultaneous broadcasting (in the case of FIG. 6) to execute weak wireless communication.
In this case, the other three PHS telephones A4 to A6 were not able to wirelessly connect to the PHS base station apparatus 2, and thus received broadcast information transmitted wirelessly from the PHS base station apparatus 2 directly. Although it is not possible to receive the information (for example, the same information as the broadcast) transmitted by the weak radio by the PHS telephone A3, the same content information as the broadcast is received and output to the user. can do.

  As described above, in the PHS wireless communication system of this example, when broadcasting to the number of terminals exceeding the number that can be wirelessly connected by the PHS base station apparatus 2 when performing simultaneous broadcasting, the PHS base station apparatus PHS telephones A1 to A3 (in this example, PHS telephone A3) that can be connected to PHS telephones PHS telephones A4 to A6 that cannot be connected to the PHS base station apparatus 2, a system other than PHS Broadcast information is relayed using wireless communication (for example, communication method for short-distance communication such as weak wireless or Bluetooth). As described above, the PHS telephones A4 to A6 (for example, such PHS telephones) that could not be connected due to insufficient lines of the PHS base station apparatus 2 by using inter-terminal communication within the PHS reception area. Broadcast information can be relayed from the PHS telephone that can be connected to the PHS base station apparatus 2 to the telephones A4 to A6 only).

Therefore, in the PHS wireless communication system of this example, the PHS telephones A4 to A6 that could not be wirelessly connected to the PHS base station apparatus 2 in the same wireless area can be broadcast simultaneously using other wireless media. By broadcasting similar information (in this example, letting you hear audio broadcasts), you are not limited to the number of lines of the PHS base station device 2, and broadcast information is notified to all telephones under the system. can do.
As described above, in the PHS wireless communication system of this example, the PHS telephones A1 to A6 can be connected to the PHS base station apparatus 2 through a wireless line by installing another wireless medium such as weak wireless or Bluetooth. It is possible to notify broadcast information to another PHS telephone using a different wireless medium. In this way, for example, the number of PHS telephones that can listen to broadcasts at one location is set to exceed the number of PHS systems that are said to be the limit of PHS systems for offices, and more people can listen to broadcasts. Is also possible.

In the base station apparatus of this example (PHS base station apparatus 2 in this example), the broadcast receiving means is configured by the function of receiving the information of the broadcast transmitted from the broadcast broadcast transmission apparatus. The broadcast transmission means is configured by the function of wirelessly transmitting broadcast information using the first communication method (in this example, the PHS communication method).
Further, in the terminal device of this example (PHS telephones A1 to A6 in this example), information is transmitted by the function of receiving broadcast information from the base station device 2 by the PHS radio 11 when wirelessly connected to the base station device 2. The reception means is configured, and the second wireless transmission means has a function of transmitting the information corresponding to the received broadcast information by the weak wireless device 12 by the second communication method (in this example, the weak wireless communication method). The second wireless receiving means is configured by the function of receiving the information transmitted by the weak wireless from the other terminal device by the weak wireless device 12, and is received by the PHS wireless device 11 or the weak wireless device 12. The reproduction means is configured by the function of reproducing the received information (in this example, voice information) by the receiver 16.
