11 ″) is inserted in a certain pattern.

Next, the incoming call control operation of the mobile station PS will be described. When the mobile station PS receives the paging channel PCH in the LCCH superframe transmitted from the base station CS in the standby state, the control unit 6 first controls the channel identifier (CI) unit in the paging channel PCH. By checking 61a, it is determined that the paging channel PCH has been received. Next, the control unit 6 sets the calling identification code (CS-ID) unit 62a and the I (PCH) information element unit 63 in the paging channel.
a, the calling identification code (CS-
(ID) from the base station CS.

Next, the control unit 6 of the mobile station PS transmits the uplink SC
CH data (see FIG. 5A) is created and transmitted to the base station CS. At this time, the destination identification code section 52a of the uplink SCCH data includes the ID (CS-I
D) and its own ID (PS)
-ID), and a message of “link channel establishment request” is inserted into the I (SCCH) information element part 54a.

On the other hand, the base station CS receives the uplink SCCH data from the mobile station PS, and checks and matches each information in the data with the corresponding information held in the own station (under the control of the own station). The mobile station PS checks whether or not it is an incoming call from the mobile station. If a match is detected, downlink SCCH data (see FIG. 5B) is created and transmitted to the mobile station PS.
At this time, the ID (CS-ID) of the own station is assigned to the source identification code unit 52b of the downlink SCCH data, and the individual ID (PS-ID) of the mobile station PS to be called is assigned to the destination identification code unit 53b.
Is inserted into the I (SCCH) information element part 54b.

In the above communication, the coincidence of the identification numbers of the uplink SCCH (link channel establishment request) transmitted by the mobile station PS and the downlink SCCH (link channel allocation) transmitted by the base station CS is detected. Thus, the establishment of the link channel is completed. Thereafter, the base station CS and the mobile station PS shift to the TCH (communication channel), and the mobile station PS generates a ringing tone. When the user performs a response operation using the ringing tone, a predetermined control sequence (for example, a control sequence described in the communication protocol RCR STD-28) is performed, and a call is started.

The mobile station PS according to the present invention is configured to be able to listen to the radio using an earphone or the like at the same time as the above-described operation of waiting for an incoming call from the base station CS (standby operation). In the present embodiment, in particular, the radio is listened to using the earphone microphone set 17 in which the microphone function is added to the earphone function.

As can be seen from FIG. 1, the earphone / microphone set 17 is provided at one end with an earphone plug which can be inserted into or removed from the earphone jack on the mobile station main body side, and the other end has a speaker section 17a and a speaker section 17a. A microphone unit 17b is provided. Thus, the radio unit 14 is operated while the earphone plug is inserted into the earphone jack, and the acoustic path switching unit 15 is switched to the illustrated side, so that the demodulated signal of the radio unit 14 is transmitted to the acoustic path switching unit 15 and the amplifier unit. The radio broadcast can be heard by taking in to the earphone microphone set 17 side through 16 and reproducing the sound by the speaker unit 17a.

In this embodiment, the earphone microphone set 17 includes the microphone section 1 together with the speaker section 17a.
7b. Thus, in a state where the acoustic path switching unit 15 is switched to the voice output path side of the communication unit 5 in the mobile station main unit, the output signal from the communication unit 5 is transmitted to the acoustic path switching unit 1.
5, while the audio is reproduced by the speaker 17a through the amplifier 16, the earphone jack, and the earphone plug, the audio input from the microphone 17b is converted into an audio signal, and the audio is input to the audio input path of the communication unit 5 through the earphone plug and the earphone jack. , The earphone / microphone set 17 can be used as an external handset.

In the mobile station PS, when trying to listen to the radio, the user turns on the radio key provided on the operation unit 10 with the earphone plug of the earphone microphone set 17 inserted into the earphone jack. When recognizing the key operation, the radio unit control unit 601 in the control unit 6 activates the radio unit 14 and switches the sound path switching unit 15 to the output path side of the radio unit 14. Thereafter, the radio unit 14 receives the broadcast radio wave via the antenna, demodulates the received signal, and outputs the demodulated signal. In this embodiment, two signals for right and left are output as output signals from the radio unit 14. The output signal of the radio unit 14 is sent to the earphone microphone set 17 through the audio path switching unit 15, the amplifier unit 16, the earphone jack, and the earphone plug, and the right audio signal and the left audio signal correspond to the respective speakers. The voice is reproduced from the unit 17a. Thereby, the user can listen to the radio broadcast by stereo sound.

Further, the mobile station PS according to the present invention registers the alarm notification information including the alarm notification time,
When the alarm notification time has been reached, an alarm notification function is provided for performing alarm notification based on the alarm notification information registered corresponding to the alarm notification time. The alarm notification function includes an alarm function for sounding an alarm sound at an alarm notification time, a simple schedule function for notifying various schedules such as meetings and meals before the scheduled time, and the like. This alarm notification function can be realized by registering alarm notification information including at least the alarm notification time in advance. The alarm registration processing unit 603 in the control unit 6 of the mobile station PS registers and manages the alarm notification information, and the alarm notification control unit 602 controls the alarm notification registered in the alarm registration processing unit 603. The alarm notification is executed based on the information.

Here, an example of the alarm registration processing in the mobile station PS will be briefly described with reference to the flowchart shown in FIG. When performing an alarm setting, the user first sets an alarm registration mode by operating, for example, a mode setting key of the operation unit 10 (step 701). At this time, the alarm registration processing unit 603 displays a screen for alarm registration on the display unit 11 by recognizing the key operation. Next, the user designates the content of the alarm to be notified by using the function keys or the like while viewing the registration screen (step 702), and further designates the time at which the content of the alarm is to be reported (step 702). Step 703). Note that the alarm content specified in step 702 includes, for example, message information displayed to make it easy to understand what the notification content is at the time of alarm notification, illustration information displayed corresponding to the message information, alarm notification sound. For example, the information includes sound quality switching switching information of the alarm notification sound in the case of selecting and operating each time from among tones and various melodies.

Subsequently, it is determined whether there is an alarm to be registered next (step 704). If there is an alarm to be registered (step 704: YES), step 70 is executed.
The processing from step 1 to step 703 is repeated. If there is no alarm to be registered next (step 704N)
O), an alarm registration operation is performed (step 704), and the process ends.

After the alarm registration operation, the alarm registration processing unit 603 stores the alarm content specified in step 702 in the memory unit 12 or the like as alarm notification information in correspondence with the alarm time specified in step 703. Thereafter, the alarm notification control unit 602 compares the alarm notification time in the registered alarm notification information with the current time, and finds one of the registered alarm notification times that has reached the current time. It is determined whether the alarm notification time has been reached or not, and if any alarm notification time has been reached, an alarm is notified based on the alarm notification information corresponding to the alarm notification time. This alarm notification can be realized by a method such as sounding the sounder 9 by the specified sound, displaying the specified message, illustration, or the like on the display unit 11, or simultaneously performing the sounding and display. .

Since the mobile station PS according to the present invention includes the radio unit 14 in addition to the alarm notification function described above, it is natural that the alarm notification time arrives during the operation of the radio unit 14. obtain.

As a control feature of the mobile station PS according to the present invention, during the operation of the radio unit 14, when the alarm notification time is reached, the operation of the radio unit 14 is stopped, and the alarm corresponding to the alarm notification time is notified. I do.

The alarm notification control during the radio operation in the mobile station PS will be described in detail with reference to the flowchart shown in FIG. As described above, when the radio key of the operation unit 10 is turned on, for example, with the earphone plug of the earphone microphone set 17 inserted into the earphone jack, the radio unit control unit 601 recognizes the key operation and activates the radio unit 14. I do. Thereafter, the user
The radio broadcast received by the radio unit 14 can be heard as stereo sound using the earphone microphone set 17 (speaker unit 17a).

During operation of the radio unit 14, the radio unit control section 601 monitors the key input from the operation section 10 to determine whether or not a radio stop operation (for example, an operation to turn off the radio key) has been performed. Monitoring (step 801), and when the operation is performed (step 80)
1YES), stops the operation of the radio unit 14, and shifts to the standby operation (step 804).

If the radio stop operation has not been performed (step 801 NO), the control unit 6 refers to the detection result of the battery remaining amount detecting unit 604 to determine whether the battery remaining amount exceeds the level “0”. (Step 80)
2).

If the remaining battery level is below the level "0" (step 802: NO), it is notified through the alarm notification control section 602 that there is no remaining battery level (step 803). The operation shifts to a standby operation (step 804).

On the other hand, when the remaining battery level exceeds the level “0” (step 802 YES), the alarm notification control unit 602 refers to the alarm notification information in the memory unit 12 through the alarm setting processing unit 603. It is determined whether or not it is the alarm notification time (step 805).

Here, if the alarm notification time has not been reached (step 805 NO), the processing from step 801 to step 805 is repeated, and the radio unit 14
While performing the control to stop the operation of the radio unit 14 by the radio stop operation during the operation of the radio and the control to notify the user when the remaining battery level falls below the level “0”, the alarm notification time is set during the radio operation. Continue monitoring whether it has reached.

If it is determined during the monitoring that the alarm notification time has been reached (step 805 YES), the control unit 6 refers to the detection result of the battery remaining amount detection unit 604 to check that the battery remaining amount is at the level “ It is determined whether or not the number exceeds "1" (however, level "1"> level "0") (step 806).

If the remaining battery level is above the level "1" (step 802 YES), the operation of the radio unit 14 is stopped via the radio unit control unit 601 (step 807), and the alarm notification control unit 60
2, an alarm is notified based on the alarm notification information corresponding to the alarm notification time (step 80).
8). Thereafter, it is determined whether or not the alarm notification has been completed (step 809). If the alarm notification has been completed (step 809 YES), the radio unit control unit 60
1 to return the radio unit 14 to the operating state (step 810).

On the other hand, when the remaining battery level is lower than the level "1" (step 802 NO), the operation of the radio unit 14 is stopped through the radio unit control section 601 (step 811), and the alarm notification control is performed. The alarm corresponding to the alarm notification time is notified through the unit 602 (step 812). Thereafter, it is determined whether or not the alarm notification has been completed (step 81).
3) If the alarm notification is completed (step 871)
3YES), and shifts to a standby operation (step 81).
4).

It is needless to say that the alarm of the low battery level in step 804 is notified in a manner different from the alarm in step 808 or step 812. Further, in step 808, the alarm is notified when the remaining battery level is relatively large, and
It is preferable that the contents of the alarm notification under the condition where the remaining battery level in the battery 12 is low are also different. This allows the user to know in advance whether the user can listen to the radio again after the alarm notification, or whether to enter the standby operation with the radio stopped.

In the mobile station PS, the actual alarm notification is performed by sounding the sounder 9 and displaying the contents of the alarm on the display unit 11 under the control of the alarm notification control unit 602. Therefore, step 8
When different types of alarm notification are performed in step 04, step 808, and step 812, it can be dealt with by changing the sound of the sounder 9 and the display content for each step.

Under the above control, when the alarm notification time is reached during the radio operation, the operation of the radio unit 14 is stopped, and the alarm is notified. Thus, in the present invention, it is possible to avoid losing the alarm notification while listening to the radio, and it is possible to reliably cope with various schedules and the like being set. Further, according to the alarm notification function of the present invention, the radio operation can always be stopped at the alarm notification time regardless of the remaining battery level. In this case, the alarm notification time is set to the stop time of the radio unit 1. By setting it, an automatic power-off function can be realized to prevent forgetting to switch off the radio.

In the above-described embodiment, an example has been described in which the radio unit 14 is added to the mobile station PS as a circuit unit that performs a function other than the call function that is the original use of the mobile station PS. The additional function unit is not limited to the radio unit.
It may be an acoustic unit such as a D player.

The present invention is not limited to the PHS, but may be applied to other mobile radio terminals such as PDC (Personal D).
It is needless to say that the present invention can be applied to digital cellular and pager.

[0070]

As described above, according to the present invention,
During the operation of the additional function unit, when the alarm notification time has been reached, the operation of the additional function unit is stopped, and the alarm is notified based on the alarm notification information registered corresponding to the alarm notification time. Even when the additional function unit is in operation, the user can be reliably notified of an alarm, and the incorporation of the additional function unit has an excellent advantage that the original alarm notification function can be prevented from being damaged.
