Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention integrates a pager and other mobile communication terminals (for example, mobile telephones) and shares one common part relating to display and notification sound generation. The present invention relates to a composite mobile communication terminal in which generation is performed by this common unit, and more particularly to one having a feature in controlling power supply.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a composite mobile communication terminal in which a pager and a mobile phone are integrated and one display unit is shared by the pager and the mobile phone. In this type of compound mobile communication terminal, as shown in FIG. 2, a group of a mobile phone unit 2 and a common control unit 3 which are supplied with power via a regulator 1 which is on / off controlled by an on / off control signal A, The power supply system is divided into a pager section 7 which is supplied with power via a regulator 6 which is on / off controlled by an on / off control signal B. The display and notification sound generation related to the mobile phone unit 2 and the pager unit 7 are displayed by the common control unit 3 which receives a control signal from the mobile phone unit 2 or the pager unit 7 and sends a display control signal and a drive signal. The part 4 and the sounder 5 are driven and executed. Therefore, the above display and notification sound generation by the display unit 4 and the sounder 5 are executed only when the regulator 1 is in the ON state and the mobile phone unit 2 and the common control unit 3 are supplied with power.

The power is supplied in the above-described configuration because normally, the regulator 1 is turned off to stop the power supply to the portable telephone section 2 and the common control section 3 which consume a relatively large amount of power. The reason is that only the regulator 6 is turned on, and power is supplied only to the pager unit 7 that consumes relatively little power so that it can be received (standby mode). In the standby mode, no call is received by the mobile phone unit 2 in the first place.
That is, the mobile phone unit 2 in this kind of compound mobile communication terminal
Is, as a rule, only for outgoing calls). The reason for providing the standby mode as described above and keeping it in the normal mode is to reduce the consumption of the power supply battery as much as possible.

[0004]

However, in the compound mobile communication terminal as described above, the pager unit 7 operates in the standby mode.
However, even when a call to the pager unit 7 is received,
Since the common control unit 3 is not supplied with power, the display unit 4 and the sounder 5 cannot notify the incoming call, and at most store the received message in a storage circuit unit (not shown) in the pager unit 7. I could only do that.
When such a message is stored, the user of the composite mobile communication terminal sends an on / off control signal A to the regulator 1 by operating a key on a key input unit (not shown) of the pager unit 7. , The regulator 1 is turned on so that the common control unit 3 is supplied with power (inevitably the mobile phone unit 2 is also supplied with power), that is, the display unit 4 and the sounder 5 can be driven. Then, the search key of the key input unit of the pager unit 7 is operated to display the stored message on the display unit 4 and recognize it. In this case, in response to the operation of the search key, data and a control signal are sent from the pager unit 7 to the common control unit 3, and the common control unit 3 controls the display of the display unit 4 based on these.

However, the confirmation of the message by the above method is not responsive, and when the message is related to the emergency notification, it may not be possible to take an appropriate response. Absent. Further, in order to recognize the stored message, it is necessary to perform a key operation for turning on the regulator 1 and an operation for the search key, and two key operations, resulting in poor operability.

The present invention has been made in view of the above circumstances, and in order to reduce the consumption of the power supply battery, the standby mode in which only the pager unit with low power consumption can receive a call can be selected. , When the pager receives a call in the standby mode, it automatically supplies the power to the function unit related to the display and the alarm sound at that time without any key operation. Another object of the present invention is to provide a composite mobile communication terminal capable of generating an incoming call notification sound.

[0007]

According to a first aspect of the present invention, there are provided a pager section which is configured by excluding a function section relating to display and notification sound generation from a pager, and a mobile communication terminal which consumes more power than the pager. The main mobile communication terminal unit having a configuration excluding the function unit related to display and notification sound generation, shared by the pager unit and the main mobile communication terminal unit,
A composite mobile communication terminal including the pager section and the common section that performs display and notification sound generation related to the main mobile communication terminal section is configured as follows.

That is, the standby mode in which power is supplied only to the pager unit to put the pager unit in the reception standby state is selected, and when there is a call to the pager unit and it is received, Power is also supplied to the common unit, and the common unit is configured to perform display and notification sound generation operations under the control of the pager unit.

According to the invention of claim 2, the following functions are added to the compound mobile communication terminal according to the invention of claim 1. That is, in the standby mode, there is a call to the pager section, receives the pager section, and also supplies power to the common section, and the common section performs display and notification sound generation operation under the control of the pager section. After that, when a certain period of time has passed, a function to stop the power supply to the common unit was added.

According to a third aspect of the invention, the main mobile communication terminal section according to the first and second aspects has a configuration in which the functional section relating to display and notification sound generation is removed from the portable telephone.
