The frame configuration is also different. Therefore, the voice channel cannot be used to send the same information to all mobile stations 4.

【0014】

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

【0015】

Therefore, in this system, an emergency call is sent from the main host station 1 to all 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 needed. In this system, a downlink control channel transmitted from the main side to the lower mobile station side is used.

【0016】

Here, the configuration of the control channel will be briefly described with reference to FIGS. 2 and 3. FIG. 2 is a schematic explanatory diagram showing the bit configuration of the control channel during standby, and FIG. 3 is a schematic explanatory diagram showing the bit configuration of the control channel during a call. The examples in Fig. 2 and Fig. 3 are used in the 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.

【0017】

As shown in FIG. 2, the signal transmitted from the base station 3 to the mobile station 4 by the control channel during standby includes a Controll-Filler-Message, which is between the mobile station 4 and the base station 3 during standby.

As shown in FIG. 5, the emergency data table 43a stores the preset emergency data in association with the corresponding emergency message, and stores the RSVD of the control channel received by the mobile station 4 in the RSVD. When the data described in the emergency data table 43a is included, the mobile station 4 is adapted to output the emergency message specified by the emergency data table 43a by voice.

【0022】

For example, if the data contained in the RSVD of the control channel is "01", the mobile station 4 outputs an emergency message "Tsunami occurred, please be careful", and if it is "02", "Tsunami occurred, please evacuate". Is output as an emergency message.

【0023】

Next, the operation of this system in an emergency will be described. In the event of an emergency, the main host station 1 instructs base station 3 to put specific data in the RSVD of Controll-Filler-Message and the RSVD of Mobil Station Controll Message via host station 2. Output. The main host station 1 is prepared with emergency data specified in the emergency data table 43a of the mobile station 4 in advance. For example, when a tsunami occurs and alerts the residents, the main host station 1 is set to Instruct base station 3 to send emergency data "01" via host station 2.

【0024】

Then, when the base station 3 receives the instruction from the main host station 1, it sends a Controll-Filler-Message containing the emergency data "01" to the RSVD by the control channel to all the standby mobile stations 4. Send out. Similarly, the base station 3 sends a Mobil Station Controll Message containing the emergency data "01" to the RSVD by the control channel to all the mobile stations 4 during the call.

【0025】

When the mobile station 4 receives the control channel regardless of whether it is in standby / call, it reads the RSVD data, checks whether emergency data is included, and if so, outputs an emergency message according to the emergency data. Performs a notification operation.

【0026】

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. If the RSVD has data, the CPU45 refers to the emergency data table 43a of the storage unit 43 to check whether the RSVD data is emergency data, and if it is emergency data, a preset sound ( A ringing sound is output to the sounder 46 during standby, and a notification sound is output during a call to alert the user. Furthermore, referring to the emergency data table 43a, an emergency message corresponding to the emergency data is output to the speaker 47 as voice. Output. As described above, the mobile station 4 reads the RSVD of the Controll-Filler-Message during standby and the RSVD of the Mobil Station Controll Message during a call.

【0027】

For example, when the emergency data of RSVD of the control channel is "01", the CPU 45 refers to the emergency data table 43a and gives the speaker 47 an urgent message "Tsunami occurred, please be careful" by voice. It is designed to output.

【0028】

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

【0029】

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 the control channel is received. As shown in FIG. 6, the CPU 45 receives data from the DSP 42 (100), refers to the emergency data table 43a, checks if there is emergency data in the RSVD (102), and if there is emergency data. (If Yes), it is determined whether the status of mobile station 4 (own machine) is standby or busy (104). If there is no urgent data (No), the process ends.

【0030】

In the standby mode, the CPU 45 outputs a preset ring tone to the sounder 46 (106), checks whether the user has answered (off-hooked) the call (108), and if it is off-hooked. , The emergency data table 43a of the storage unit 43 is referred to, the emergency message corresponding to the emergency data is read, and the emergency message is output to the speaker 47 as a voice (110), and the process is completed.

【0031】

Further, in the process 104, when the mobile station 4 (own machine) is in a call, the CPU 45 outputs a notification sound (melody, tone, etc.) indicating that emergency data has been input to the speaker 47. (120) Then, with reference 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 ends. In this way, the processing in the CPU 45 of the mobile station 4 is performed.

【0032】

According to the mobile phone system according to the embodiment of the present invention, the mobile station 4 is provided with an emergency data table 43a that stores emergency data in association with an emergency message corresponding to the emergency data, and in an emergency, the base station 3 provides. According to the instruction from the main host station 1, the RSVD of the message transmitted by the control channel is sent with specific emergency data, and when the mobile station 4 receives the control channel, the RSVD data is read and the emergency data table is displayed. Since the mobile phone system refers to 43a and outputs the corresponding emergency message as voice to the speaker 47, it is possible to make an emergency call from the main host station 1 to all mobile stations 4 in an emergency. It can be used as a means of transmitting information other than mobile phones and radio, and has the effect of being able to provide emergency information to as many people as possible.

【0033】

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

【0034】

Further, in this system, since the emergency call is sent using the control channel instead of the voice channel, there is an effect that the emergency message can be heard without hanging up even during a call.

【0035】

Furthermore, when the main host station 1 outputs an emergency data transmission instruction to the host station 2, a specific host station 2 can be selected and output, so that only the mobile station 4 in a specific area is urgent. It has the effect of allowing information to flow.

【0036】
