Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable telephone, a PH
More specifically, the present invention relates to a mobile wireless terminal device such as an S terminal, and more specifically, a wireless unit for performing wireless communication with a communication facility of a mobile communication system, and a functional unit for performing an operation based on a predetermined function regardless of the wireless communication. The present invention relates to a mobile radio terminal having the same.

[0002]

2. Description of the Related Art In recent years, mobile terminal devices, for example, portable telephones have been realized which have various functions such as a mail transmitting / receiving function and a browser function in addition to a voice communication function. Such a mobile phone is directly involved in the wireless communication in addition to a wireless unit for performing wireless communication with a communication facility (for example, a base station) of a mobile communication system (for example, a PDC: Personal Digital Cellular system). It has a part that operates based on a function without it. Functions that are not directly related to the wireless communication include, for example, display of received mail, sent mail, editing of mail, registration and correction of a telephone directory, display of web information received and stored by a browser function, and various conditions. Settings (password settings, ringtone settings and editing, etc.), data exchange with external terminals (personal computers), and the like.

[0003] Such a cellular phone performs a location registration (transmission) operation and a standby operation (reception) using a radio unit when it is within a service area. In addition, when the mobile phone is out of the service area, the location registration operation is not performed, but the cell search operation is performed. In such a state, the user can perform various processes (editing mail, exchanging data with an external terminal, and the like) by enabling a function not directly related to the wireless communication.

Conventionally, in a mobile communication terminal device such as a cellular phone, a location registration operation or a location registration operation is always performed irrespective of the presence or absence of processing based on functions not directly related to wireless communication.
From the necessity of performing standby operation and cell search operation,
The supply and cutoff of power to the wireless unit that realizes wireless communication and the supply and cutoff of power to parts that are not directly related to the wireless communication are performed simultaneously according to the on / off state of the power switch.

[0005]

As described above, in the conventional mobile radio terminal, a radio unit for realizing radio communication,
Since the power supply control for the parts not related to the wireless communication function is performed collectively, power consumption may be wasted depending on the situation.

For example, a user who wants to enable a part not related to the wireless communication function to create and edit mail, check received mail, exchange data with an external terminal, etc.
While such processing is being performed, there is a case where no incoming call or outgoing call is desired for the wireless communication terminal device.
In such a case, supplying power to a wireless unit that realizes wireless communication wastes power consumption.

On the other hand, when the user is performing voice communication and data communication using the wireless communication function, it is impossible to perform processing using a function irrelevant to the wireless communication function. Supplying power to a portion not related to the wireless communication function wastes power consumption.

When regulation information indicating that connection cannot be established from the network due to congestion or the like is received, since transmission and reception cannot be performed from the beginning, supplying power to a radio unit for realizing radio communication is a waste of power consumption. .

[0009] Further, when the voice communication is locally restricted (such as a concert hall), performing only the position registration operation and the standby operation using the wireless communication function wastes power consumption.

Furthermore, in a situation where the remaining amount of the battery mounted on the mobile radio terminal device is low, supplying power to a portion that realizes a function not required by the user wastes power consumption.

It is an object of the present invention to provide a mobile communication terminal device capable of reducing power consumption as much as possible while using functions as much as possible.

The circuit control unit 40 includes a control signal processing unit / communication data processing unit 41
And generates a power supply control signal to a power supply control unit 100, which will be described later, based on an operation signal corresponding to the operation of the keyboard unit 32, and displays the information received by the wireless unit 10 and various other information on the display unit. 3
1 is displayed. The application unit 50 performs processing according to various programs such as a browser and a mailer, and stores a telephone directory, an address book, received mail, transmitted mail, acquired web information, and the like. The application processing unit 51 and a storage circuit 52.

The portable telephone further includes a battery 7
0, a remaining amount detection circuit 60 and a power control unit 100. The power control unit 100 includes a power circuit 101 and a power control circuit 102. The power supply circuit 101 converts the voltage of the battery 70 into a stabilized predetermined power supply voltage,
The power supply voltage is supplied to the power supply control circuit 102. The power control unit 102 is a wireless unit 10, a communication unit 20, a display / operation unit 30, a circuit control unit 40, and an application unit 50 based on the power supply control signal from the circuit control unit 40 described above.
Control of the supply of the power supply voltage to. The remaining amount detection circuit 60 detects the remaining amount of the battery 70. The detection signal from the remaining amount detection circuit 60 is supplied to the power supply control circuit 102, and the power supply control circuit 102 can control the supply of the power supply voltage to each unit based on the detection signal.

In the mobile phone having the above configuration,
The application unit 50 is a functional unit that operates based on a predetermined function irrespective of wireless communication by the wireless unit 10, such as editing mail, updating a telephone directory and an address book stored in the storage circuit 52, and updating the storage circuit 52. Has a function unit for reading out received mails, transmitted mails and web information stored in the Web browser.

The power supply control circuit 102 in the power supply control section 100 performs processing according to, for example, a procedure as shown in FIG.

In FIG. 2, when the power control circuit 102 recognizes that the power switch has been turned on (S
0), power supply control is performed for each unit in a predetermined initial state (S1). By the power supply control in this initial state, for example, all parts, that is, the radio unit 10 and the communication unit 2
0, a power supply voltage is supplied to each of the display / operation unit 30, the circuit control unit 40, the application unit 50, and the remaining amount detection circuit 60. In this state, the power supply control circuit 102 determines whether a power supply control signal has been received from the circuit control unit 40 in response to an operation on the keyboard 32 (S2).
When determining that the power supply control signal has been received (YES in S2), the power supply control circuit 102 controls the power supply to each unit so as to be in the power supply state specified by the power supply control signal.

For example, when the user recognizes that the user is out of the service area or when the user does not particularly desire wireless communication, the address book is updated, the mail is edited, the received mail, the received mail is read and stored. When the user performs an operation related to power control in such a state with the keyboard 32 in order to perform data processing such as browsing of the performed web information, power supply from the circuit control unit 40 in response to the operation is performed. Based on the control signal, as shown in FIG. 3, the supply of the power supply voltage to the wireless unit 10 is interrupted, and the supply of the power supply voltage to other parts including the application unit 50 is maintained (S31). Hereinafter, this state is referred to as state A.

In this state A, the power supply voltage is not supplied to the radio unit 10, and the location registration (transmission) operation, the standby operation (reception), and the cell search operation are not performed. In this manner, power consumption can be saved because the power supply voltage is not supplied to the wireless unit 10. Then, in such a state that the power consumption is reduced, the application unit 50 performs various data processing (update of telephone directory, address book, editing of mail, received mail, transmitted mail, etc.) in accordance with the operation of the display / operation unit 30 by the user. (E.g., reading mail, browsing accumulated web information, etc.).

In addition, when the user performs an operation related to power control in such a state with the keyboard 32 in a state of requesting a telephone call without particularly requesting the above-described data processing, the operation is performed. As shown in FIG. 4, the supply of the power supply voltage to the application unit 50 is interrupted based on the power supply control signal from the circuit control unit 40 in response to the Is maintained (S32). Hereinafter, this state is referred to as state B.
That.

In this state B, the application unit 50
Is cut off, the power consumption can be saved accordingly. Then, in a state where such power consumption is saved, when the mobile phone is located within the service area, the mobile phone performs a position registration (transmission) operation and a standby operation (reception) by a function of the wireless unit 10. . Then, the user makes a call according to the outgoing call and the incoming call. When the mobile phone is out of the service area, the cell search operation is repeatedly performed by the function of the radio unit 10.

Further, the user may wish to receive various information such as confirmation of incoming voice call and reception of e-mail, but may not desire outgoing voice call or mail transmission. In such a case, when the user performs an operation related to power control in such a state using the keyboard 32, as shown in FIG. 5, based on a power supply control signal from the circuit control unit 40 in response to the operation. Then, the supply of the power supply voltage to the transmission circuit 13 of the wireless unit 10 is shut off, and the supply of the power supply voltage to other parts including the wireless unit 10 and other parts including the application unit 50 is maintained (S33). . Hereinafter, this state is referred to as state C.

In this state C, the transmission function of the portable telephone is invalidated, so that voice signals, mails and the like cannot be transmitted, but the receiving operation of various information and the data processing as described above become possible. Since the supply of the power supply voltage to the transmission circuit 13 is cut off, power consumption can be saved.

In some cases, the user wants to keep all functions of the mobile phone enabled. In this case, when the user performs an operation related to the power control in such a state on the keyboard 32, the circuit control unit 40 responding to the operation.
Based on the power supply control signal from, the supply of power supply to all parts including the wireless unit 10 and the application unit 50 is maintained (S34). This state is hereinafter referred to as state D. In this state D, the above-described data processing can be performed while the location registration operation, the standby operation, and the cell search operation are performed, as in the conventional mobile phone.

As described above, the power supply control circuit 102
Is based on a power supply control signal from the circuit control unit 40 in response to a user's operation on the keyboard 32, and controls power supply to each unit in any of the states A, B, C, and D described above. I do. In this state, the power control circuit 102 further determines whether the power switch has been turned off (S4) and determines whether a new power supply control signal has been received from the circuit control unit 40 (S4).
Repeat step 5).

The process of such processing (NO in S4, S5
When the user operates the keyboard 32 in a request for a new power control state, a power supply control signal corresponding to the operation is transmitted from the circuit control unit 40 to the power control circuit 1.
02 (YES in S5). Then, based on the new power supply control signal, the power supply control circuit 102 supplies power to each unit so as to be in one of the states A, B, C, and D as described above. Perform control. Thereafter, the power control circuit 102 repeatedly determines whether the power switch has been turned off (S4) and determines whether a new control signal has been received from the circuit control unit 40 (S5). In this process, when it is determined that the power switch has been turned off (YES in S4), power supply control circuit 102 cuts off the supply of the power supply voltage to each unit (S6) and ends the process.

In the portable telephone as described above, the user operates the keyboard 32 and operates the power switch, as shown in FIG. A where the supply of the power supply voltage to the
State B in which the supply of the power supply voltage to power supply 0 is stopped, radio unit 1
The power supply control state can be transited to any one of the state C, in which the power supply voltage is not supplied to the transmission circuit 13, and the state D in which the power supply voltage is supplied to all parts. Therefore, power supply control can be performed with appropriate power consumption according to the function desired by the user. In particular, the power supply control in the state A, the state B, and the state C can reduce the power consumption as compared with the power supply control in the conventional mobile phone.

In the above example, the initial state (S1)
Was in a state where power was supplied to all parts,
From the viewpoint of further reducing power consumption, the above initial state can be set to the above-described state A (a state in which the power supply voltage to the wireless unit 10 is cut off).

In the above example, the keyboard 3 by the user
The state of the power supply control can be changed to any of the states according to the operation of step 2. For example, the state is changed based on a control signal corresponding to the remaining amount of the battery 70 detected by the remaining amount detection circuit 60. The state of the power supply control that can be performed can be limited.

For example, if the remaining amount of the battery 70 is equal to or greater than the first remaining amount, the power supply control circuit 102 enables transition to any of the states A, B, C, and D, If the amount is equal to or less than the second remaining amount that is smaller than the first remaining amount, only the power supply control in the state A is enabled, and the remaining amount of the battery 70 is equal to the first remaining amount and the second remaining amount. If it is between the amounts, the power supply control in the states B and C can be performed.

By limiting the state of the power supply control that can be changed according to the remaining amount of the battery 70,
When the battery 70 is greatly consumed, the mobile phone is used in a state where power consumption is further reduced.

Further, the power supply control circuit 102 can directly control the power supply based on a control signal corresponding to the remaining amount of the battery 70 detected by the remaining amount detection circuit 60.

For example, if the remaining amount of the battery 70 is equal to or more than the first remaining amount, the power control circuit 102
The power supply control is performed in a state where the power supply voltage is supplied to all parts. If the remaining amount of the battery 70 is equal to or less than the second remaining amount which is smaller than the first remaining amount, the state A (to the wireless unit 10 Power supply control in a state in which the power supply voltage supply is interrupted, and if the remaining amount of the battery 70 is between the first remaining amount and the second remaining amount, the state C (transmitting circuit 13
Power supply control in a state in which the supply of the power supply voltage to the power supply is interrupted). In this case, the power supply control in the state B (a state in which the supply of the power supply voltage to the application unit 50 is cut off) is not performed.

Further, power supply control to each part of the portable telephone can be performed based on a control signal from an external device (for example, a personal computer). In this case, the mobile phone is configured, for example, as shown in FIG.

Referring to FIG. 7, this portable telephone has a radio unit 10, a communication unit 20, and a communication unit 20 as in the example described above (see FIG. 1).
It has a display / operation unit 30, a circuit control unit 40, an application unit 50, a remaining amount detection circuit 60, and a battery 70,
Further, the external device interface 80 (Bluetooth, Ir-D
A, USB, serial interface, etc.). In the external device interface 80, the power supply voltage supplied by the power supply control circuit 102 is controlled. The external device 200 is connected to the external device interface 80, and the mobile phone can exchange data with the external device 200 via the external device interface 80.

In such a mobile phone, power supply control circuit 102 performs processing according to the procedure shown in FIG. 2, as in the above-described example.

When the user needs the function of the radio unit 10 for sending and receiving e-mails and the like, when a predetermined operation is performed on the external device 200 so that the power supply control in the state B is performed, the operation is performed. Is supplied to the circuit control unit 40 via the external device interface 80. For example, when a power supply control signal corresponding to the control signal is supplied from the circuit control unit 40 to the power supply control circuit 102 that performs power control (S0, S1) in the initial state (state D) (S2). YES), the power supply control circuit 102 switches the state of the power supply control to the state B (S32). That is, in the mobile phone, FIG.
As shown in (1), power is supplied to each unit (including the wireless unit 10) except the application unit 50.
As a result, the external device 200 can transmit and receive mail via the external device interface 80 and the wireless unit 10 of the mobile phone.

For example, when the user of the external device 200 does not want to perform data communication such as sending and receiving mail, but wants to acquire information stored in the storage circuit 52 of the application unit 50 of the mobile phone, the state A When a predetermined operation is performed on the external device 200 to perform power supply control, a control signal corresponding to the operation is supplied to the circuit control unit 40 via the external device interface 80. When a power supply control signal corresponding to the control signal is supplied from the circuit control unit 40 to the power control circuit 102 (YE in S2)
S), the power control circuit 102 controls the power of each unit in the state A (S31). That is, in the mobile phone,
As shown in FIG. 8, power is supplied to each unit (including the application unit 50) except the wireless unit 10.
As a result, the external device 200 can receive data from the application unit 50 of the mobile phone via the external device interface 80 in a state where operations such as a position registration operation, a standby operation, and a cell search are not performed.

For example, when the user of the external device 200 does not want to send a mail using a mobile phone, but wants to receive the mail, the external device 200 is controlled to supply the power in the state C. When the operation is performed, the power supply control signal corresponding to the operation is supplied to the power supply control circuit 102 in the same manner as described above (YE in S2).
S). The power control circuit 102 controls the power of each unit in the state C (S33). That is, in the mobile phone, as shown in FIG. 10, power is supplied to each part (including the receiving circuit 14 of the wireless unit 10) except the transmitting circuit 13 of the wireless unit 10. As a result, the external device 200
Information such as e-mail cannot be transmitted, but information such as e-mail can be received via the mobile phone.

According to the above example, the portable telephone is connected to the external device 2.
When the portable telephone is connected to 00 and used, it is possible to control the power of the portable telephone with appropriate power consumption according to the function desired by the user. Then, similarly to the above-described example (see FIG. 1), the power consumption control is particularly performed in the state A, the state B, and the state C to reduce the power consumption as compared with the power supply control in the conventional mobile phone. be able to.

Further, it is also possible to control the power supply to each part of the portable telephone based on regulation information transmitted from an external facility.

Also in this case, the power supply control circuit 102
The processing is performed according to the procedure shown in FIG.

For example, regulation information may be transmitted from the network side to regulate communication by the mobile phone due to congestion, a situation in which the transmission operation of the mobile phone is inappropriate, or the like. In such a case, power supply control is performed in an initial state (S0, S1). When the wireless unit 10 of the mobile phone receives such regulation information, power supply from the circuit control unit 40 in response to the regulation information is performed. The control signal is, for example, a power control circuit 102 that controls power supply in an initial state (state D).
(S2). The power supply control circuit 102 that has received the power supply control signal switches the state of the power supply control to, for example, the state A or the state C (S31, S33).
That is, in the mobile phone, the supply of the power supply voltage to the entire radio unit 10 or the transmission circuit 13 is cut off. As a result, the above-described data processing by the application unit 50 can be performed in a state where transmission (transmission) of radio waves is not performed according to the regulation information.

As described above, by controlling the power supply to each part of the mobile phone based on the regulation information, transmission regulation is surely performed, and unnecessary power consumption can be reduced.

When the state of the power supply control is changed to state C based on the regulation information, the reception function is enabled. With the disappearance of the regulation information, the state of the power supply control can be automatically returned from the state C to the state D.

The restriction of the local functions of the mobile phone is not performed based on the control information transmitted from the network side as described above, but rather, the restriction area information notified from the network in advance and the mobile phone detects the restriction. It is also possible to carry out based on the position information. In this case, the mobile phone is configured, for example, as shown in FIG.

In FIG. 11, this portable telephone has a radio unit 10 and
Communication unit 20, display / operation unit 30, circuit control unit 40, application unit 50, remaining amount detection unit 60, and battery 7
0, and further has a position detection unit 90. The position detection unit 90 is a GPS (Global Positioning System).
m) to detect the location of the mobile phone,
It has a GPS receiving circuit 91 and a GPS control circuit 92. The GPS control circuit 92 calculates the position of the mobile phone based on the signal from the satellite received by the GPS receiving circuit 91. Then, position information corresponding to the calculated position is supplied from the GPS control unit 92 to the circuit control unit 40.

The circuit control unit 40 determines whether the current position is within any of the restricted areas based on the position information from the position detecting unit 90 and the information on the restricted area of each function previously received. . Then, a power supply control signal according to the determination result is supplied from the circuit control unit 40 to the power supply control circuit 102. Then, the power supply control circuit 102 performs processing in accordance with the procedure shown in FIG. 2, and controls power supply to each unit according to the supplied power supply control signal (S
2, S31, S32, S33, S34, etc.).

For example, an area in which the voice communication function is restricted (for example, a concert hall), an area in which wireless communication should be given priority over data processing (for example, an area in which emergency communication should be given continuous priority in the event of a disaster, etc.). ),Also,
Information about an area where the transmission function is restricted (for example, an area where congestion is expected in a disaster or the like) is notified to the mobile phone in advance, and the area information is stored inside the mobile phone.

In such a state, the circuit control unit 40 determines that the portable telephone is present in the area where the voice communication function is restricted based on the position information from the position detection unit 90 and the area information. Then, the circuit control unit 40
Supplies a power supply control signal to the power supply control circuit 102 so that power supply control in state A is performed. Under the control of the power supply control circuit 102 based on the power supply control signal, as shown in FIG. 12, power is supplied to each unit (including the application unit 50) except the wireless unit 10. As a result, in an area where the voice communication function is restricted, useless power supply to the radio unit 10 can be avoided, and the restriction of the voice communication function is reliably performed.

If the circuit control unit 40 determines that the portable telephone is in an area where the wireless communication should be given priority over the data processing based on the position information from the position detection unit 90 and the area information, the circuit The control unit 40 supplies a power supply control signal to the power supply control circuit 102 so that the power supply control in the state B is performed. By the control of the power supply control circuit 102 based on the power supply control signal, FIG.
As shown in (1), power is supplied to each unit (including the wireless unit 10) except the application unit 50. As a result, useless power supply to the application unit 50 can be avoided in an area where wireless communication is to be performed prior to data processing.

Further, if the circuit control unit 40 determines that the portable telephone is present in the area where the transmission function is to be restricted, based on the position information from the position detection unit 90 and the area information, the circuit control unit 40 will be described. Supplies a power supply control signal to the power supply control circuit 102 so that power supply control in state C is performed. As shown in FIG. 14, by controlling the power supply control circuit 102 based on the power supply control signal, a part of the wireless unit 10 excluding the transmission circuit 13 and a part other than the wireless unit 10 (including the application unit 50) are controlled. Power is supplied. As a result, in the area where the transmission function is to be restricted, the transmission circuit 1 of the radio unit 10
3 can be avoided.

In each of the above examples, the supply and cutoff of power to the radio unit 10 and the supply and cutoff of power to the application unit 50 including a functional unit that operates according to a predetermined function regardless of wireless communication are individually controlled ( State A, state B, and state D) are used. However, in a mobile phone, the location registration operation, the standby operation, and the cell search operation require particularly power. ) May be individually controlled to supply and cut off power to the wireless unit 10 while power is constantly supplied. In this case, the state of the power supply control transitions between state A and state D.

As described above, when the supply and cutoff of the power to the radio unit 10 are individually controlled, the supply and cutoff of the power to the transmission circuit 13 are further performed while the power is supplied to the radio unit 10. Control may be performed individually.
In this case, the state of the power supply control transitions between state A, state C, and state D.

In each of the above examples, the power supply control circuit 1
