  The present invention relates to a mobile phone system, and more particularly, to a mobile phone system capable of forcing a report via a mobile phone in an emergency or a disaster and notifying many people of the danger.

  Conventionally, TV and radio are the most commonly used methods for informing people in advance of emergencies and disasters, and although they are highly effective, modern people with a wide range of actions are not necessarily in the information society. It is not always in contact with the radio.

  Under such circumstances, mobile phones are widely spread due to their ease of use, and are highly advantageous as terminals that can always obtain information.

  However, in the above conventional mobile phone system, there is no system for forcibly transmitting information by taking advantage of the fact that the terminal is always in contact with the user, so that many people can be notified in an emergency or emergency situation. There is a problem that the advantage of the mobile phone that can be used is not fully utilized.

  The present invention has been made in view of the above circumstances, and provides a mobile phone system capable of forcibly reporting information to a mobile phone from the top of the system and providing information to an emergency or emergency to many people. The purpose is to provide.

  The present invention for solving the problems of the above conventional example, in a mobile phone system, a main host station that outputs an instruction to a base station, a base station that transmits specific data according to an instruction from the main host station, When specific data transmitted from the base station is received, it is judged whether it is in a standby state or in a call, and if it is in a standby state, a ringing tone is output, and if a call is in progress, information corresponding to the specific data is displayed. In the event of an emergency, an emergency call can be sent from the main host station to the mobile station to notify the danger regardless of whether it is on standby or on a call.

  In addition, the present invention is a mobile station in a mobile phone system that determines whether a sounder that outputs a ringing tone, a speaker that outputs sound, and whether or not a call is on standby when receiving specific data. It is characterized by having a processing unit that outputs a ringing tone to the sounder when in the middle, and outputs information corresponding to specific data to the display when in the middle of a telephone conversation. Can be notified.

  According to the first aspect of the present invention, when a specific data is transmitted from the base station to the mobile station in response to an instruction from the main host station, and the mobile station receives the specific data, whether the mobile station is on standby or talking. The mobile phone system displays the information corresponding to the specific data on the display if it is in a call, and outputs a ringing tone if it is waiting. Therefore, it is possible to forcibly make an emergency call and to notify the danger regardless of whether it is in standby / calling, and to transmit emergency information to many people.

  According to the second aspect of the present invention, it is determined whether a sounder that outputs a ringing tone, a speaker that outputs sound, and whether or not a call is in a waiting state when specific data is received. Since the mobile station is provided with a processing unit that outputs a ringing tone and outputs information corresponding to the specific data to the display when a call is in progress, the danger can be notified regardless of whether the call is on standby or in a call. This has the effect of transmitting emergency information to many people.

Embodiments of the present invention will be described with reference to the drawings.
In the case of an emergency, the mobile phone system according to the embodiment of the present invention forces an emergency from a base station to a mobile terminal via a control channel in response to an instruction from a main host station that controls the entire mobile phone system. By making a report, it is possible to quickly send an emergency message to users, and to provide emergency information to more people.

  First, the configuration of the mobile phone system will be described with reference to FIG. FIG. 1 is a system configuration block diagram of a mobile phone system. As shown in FIG. 1, the mobile phone system includes a main host station 1 that controls the entire system, a host station 2 connected to the main host station 1, a base station 3 connected to the host station 2, and a user. The mobile station 4 is carried.

  Then, the mobile station 4 communicates with the base station 3, the base station 3 sends the location information of the mobile station 4 to the higher-order host station 2, and similarly, the host station 2 moves to the main host station 1. Station 4 information is sent out. Conversely, when an instruction or information is transmitted from the main host station 1 to the lower host station 2, the same information can be transmitted to all the mobile stations 4 via each base station 3. Yes. In this system, by utilizing this fact, an emergency call is sent from the main host station 1 to all the mobile stations 4.

  Here, transmission / reception of audio signals between the mobile station 4 and the base station 3 is performed using different frequencies (audio channels) in order to prevent interference with other mobile stations 4. The frame configuration is also different. Therefore, the voice channel cannot be used to send the same information to all the mobile stations 4.

  Furthermore, there are two states of the mobile station 4, that are standby and during a call. When an emergency call is transmitted, it is necessary to transmit the same information in either state.

  Therefore, in this system, an emergency call is sent from the main host station 1 to all the mobile stations 4 using the control channel. The control channel is a channel in which all base stations 3 and mobile stations 4 are always connected in the same frame configuration, and is used for location registration, channel allocation, and the like. The control channel is provided with an RSVD (Reserved) field (hereinafter simply referred to as “RSVD”) as a part to which new information can be added as necessary. In this system, a downlink control channel transmitted from the main side toward the lower mobile station side is used.

  Here, the configuration of the control channel will be briefly described with reference to FIGS. FIG. 2 is a schematic explanatory diagram illustrating the bit configuration of the control channel during standby, and FIG. 3 is a schematic explanatory diagram illustrating the bit configuration of the control channel during a call. The examples in FIGS. 2 and 3 are used in analog TACS (Total Access Communications System) and AMPS (Advanced Mobile Phone Service), but the digital system has a similar configuration. The description is omitted here.

  As shown in FIG. 2, the signal transmitted from the base station 3 to the mobile station 4 by the control channel at the time of standby includes Controll-Filler-Message, and between the mobile station 4 and the base station 3 at the time of standby, They are connected with the same frame configuration at a constant period. RSVD is provided in Controll-Filler-Message, and in this system, emergency call data is entered here according to an instruction from the main host station 1, and the controll-Filler-Message receives controll from each base station 3 to the mobile station 4 waiting. -Filler-Message is sent out.

  Further, as shown in FIG. 3, the control channel during a call is a Mobil Station Controll Message, which is connected with the same frame configuration between the mobile station 4 and the base station 3 during the call. RSVD is provided in both AMPS. In this system, the base station 3 puts emergency call data (emergency data) into the RSVD and sends it to the mobile station 4 that is talking in the same manner as in the standby mode. Send a Message.

  That is, in the event of an emergency, the main host station 1 outputs an instruction to each base station 3 to put specific emergency data in RSVD of Controll-Filler-Message and RSVD of Mobil Station Controll Message. By using the control channel, emergency data can be transmitted to all the mobile stations 4 on standby and the mobile stations 4 in communication.

  Next, the mobile station 4 on the receiving side will be described using FIG. FIG. 4 is a configuration block diagram showing the configuration of the mobile station 4 of this system. As shown in FIG. 4, the basic configuration of the mobile station 4 is the same as in the prior art, and a radio unit 41 that transmits and receives radio signals and a DSP (Digital Signal Processor) that encodes and decodes digital signals. 42, a storage unit 43 that stores data, a display 44 that displays data, a CPU 45 that performs processing associated with communication, a sounder 46 that outputs a ringing tone, and a speaker 47 that outputs sound. ing. Although originally provided with an audio signal processing unit for encoding / decoding an audio signal, an audio input unit, and the like, they are omitted here because they are not directly related to the present invention.

  As a feature of the mobile station 4 of this system, an emergency data table 43a is provided in the storage unit 43. FIG. 5 is an explanatory diagram of the emergency data table 43a. As shown in FIG. 5, the emergency data table 43a stores emergency data set in advance and corresponding emergency messages in association with each other. The RSVD of the control channel received by the mobile station 4 When data described in the emergency data table 43a is included, the mobile station 4 outputs an emergency message defined by the emergency data table 43a by voice.

  For example, if the data included in the RSVD of the control channel is “01”, the mobile station 4 outputs an emergency message “Take a tsunami, please be careful”, and if it is “02”, “Take a tsunami and evacuate” The urgent message is output.

  Next, the operation of this system in an emergency will be described. When an emergency occurs, the main host station 1 instructs the base station 3 to enter specific data into the RSVD of the Controll-Filler-Message and the RSVD of the Mobil Station Controll Message via the host station 2. Output. In the main host station 1, emergency data defined in the emergency data table 43a of the mobile station 4 is prepared in advance. For example, when a tsunami occurs to call attention to the residents, the main host station 1 The base station 3 is instructed to send the emergency data “01” via the host station 2.

  When receiving the instruction from the main host station 1, the base station 3 sends a Controll-Filler-Message containing emergency data “01” to the RSVD to all the mobile stations 4 that are waiting. Send it out. Similarly, the base station 3 sends a Mobil Station Controll Message including emergency data “01” to the RSVD through the control channel to all mobile stations 4 in a call.

  When receiving the control channel, the mobile station 4 reads the RSVD data to check whether emergency data is contained, and if it is entered, the mobile station 4 outputs an emergency message or the like according to the emergency data. A notification operation is performed.

  Specifically, when the radio unit 41 of the mobile station 4 receives the control channel, the DSP 42 decodes the received signal and sends the data to the CPU 45. When there is data in the RSVD, the CPU 45 refers to the emergency data table 43a in the storage unit 43 to check whether the RSVD data is emergency data. A ringing tone during standby and a notification tone during a call are output to the sounder 46 to alert the user, and the emergency data corresponding to the emergency data is referred to the emergency data table 43a as a voice to the speaker 47. Output. As described above, the mobile station 4 reads the RSVD of Controll-Filler-Message when waiting, and reads the RSVD of Mobil Station Controll Message during a call.

  For example, when the emergency data of the control channel RSVD is “01”, the CPU 45 refers to the emergency data table 43a and gives an emergency message “Please note that a tsunami has occurred” to the speaker 47 by voice. It is designed to output.

  As a result, in this system, the main host station 1 can forcibly make an emergency call to all the mobile stations 4 in an emergency, taking advantage of the mobile phone that is always in contact with the user, Even when it is difficult to obtain information from television or radio, urgent information can be transmitted to as many people as possible.

  Next, the operation of the CPU 45 will be specifically described with reference to FIG. FIG. 6 is a flowchart showing the operation of the CPU 45 of the mobile station 4 when a control channel is received. As shown in FIG. 6, when receiving data from the DSP 42 (100), the CPU 45 refers to the emergency data table 43a and checks whether there is emergency data in the RSVD (102). In the case of Yes, it is determined whether the state of the mobile station 4 (own device) is a standby or busy (104). If there is no emergency data (No), the process is terminated.

  If it is standby, the CPU 45 outputs a preset ring tone to the sounder 46 (106), checks whether the user has answered the phone (off-hooked) (108), and if it is off-hooked, Then, referring to the emergency data table 43a of the storage unit 43, an emergency message corresponding to the emergency data is read out and output to the speaker 47 as voice (110), and the process is terminated.

  In the process 104, when the state of the mobile station 4 (own device) is busy, the CPU 45 outputs a notification sound (melody, tone, etc.) notifying that emergency data has entered to the speaker 47. (120) Subsequently, referring to the emergency data table 43a, a voice emergency message corresponding to the emergency data is output to the speaker 47 over the call (122), and the process is terminated. In this way, processing in the CPU 45 of the mobile station 4 is performed.

  According to the mobile phone system according to the embodiment of the present invention, the mobile station 4 includes the emergency data table 43a that stores the emergency data and the corresponding emergency message in association with each other. In accordance with an instruction from the main host station 1, specific emergency data is transmitted in the RSVD of the message transmitted by the control channel, and when the mobile station 4 receives the control channel, the RSVD data is read and the emergency data table 43a, the mobile phone system outputs a corresponding emergency message as a voice to the speaker 47. In an emergency, it is possible to make an emergency call from the main host station 1 to all the mobile stations 4, and the TV It can be used as a means of communication other than radio and radio, and provides emergency information to more people There is an effect that can be bet.

  Further, in the present system, the case where the message is output as voice has been described, but it may be displayed on the display 44 in addition to the voice. In addition, the type of ringing tone or notification sound may be changed depending on the degree of urgency. In such a case, ringing tone and notification tone data are also specified in the emergency data table 43.

  Furthermore, in this system, an emergency call is transmitted using a control channel instead of a voice channel, so that an emergency message can be heard without hanging up even during a call.

  Furthermore, when the main host station 1 outputs an emergency data transmission instruction to the host station 2, it is also possible to select and output a specific host station 2, so that only the mobile station 4 in a specific area is urgently selected. There is an effect that information can flow.

  Next, a mobile phone system according to another embodiment of the present invention will be described. In the example described above, an analog system has been described, but a mobile phone system according to another embodiment is used for a mobile phone system using a digital system such as PDC (Portable Digital Cellular). The schematic configuration of the system and the configuration of the mobile station 4 are the same as those of the analog system shown in FIGS.

  Even in the digital system, as in the analog system, emergency data is transmitted using a signal transmitted from the base station to the mobile station via the control channel. In the digital system, there is a broadcast information message (BCCH) as a message transmitted from the base station to the mobile station, and the emergency information preset in the extended information element length in the BCCH is transmitted. Since the BCCH is common information during standby and during a call, an emergency call can be sent to all mobile stations using the BCCH regardless of the state of the mobile station.

  That is, in an emergency, the main host station instructs the base station via the host station to enter specific emergency data in the BCCH extended information element length, and the base station follows the instruction to extend the BCCH extended information element length. The emergency data is put in and sent to all the mobile stations 4 through the control channel.

  As in the case of analog, the mobile station is provided with an emergency data table that associates preset emergency data with an output message. When the mobile station receives the BCCH from the base station, the CPU Checks the data of the extended information element length, and if emergency data is included, refers to the emergency data table and outputs a corresponding message.

  According to the mobile phone system according to another embodiment of the present invention, in the digital mobile phone system, the mobile station is provided with the emergency data table for associating the emergency data with the output message, and the main host station The base station outputs an instruction to send the specific emergency data in the extended information element length of the BCCH, and the base station sends the BCCH to the mobile station according to the instruction from the main host station. When specific emergency data is included in the extended information element length of the BCCH received by the control channel, a message corresponding to the emergency data is output with reference to the emergency data table. The telephone system also sends an emergency call to all mobile stations regardless of whether they are on standby or on a call, and the mobile station sends a message. It can be output as over-di, there is an effect that it is possible to transmit the emergency information to the user.
