Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention determines whether or not to turn on the power of the entire system in a portable mobile terminal having a communication function when a communication request is detected (when a call arrives). The present invention relates to a device for suppressing automatic power-on in a communication terminal to be executed.

In particular, in a portable communication terminal using a battery, it is necessary to avoid unnecessary battery consumption as much as possible.
Therefore, it is necessary to provide a device that determines whether the communication request is useful or necessary, and suppresses power-on if unnecessary.

[0003]

2. Description of the Related Art In recent years, along with the miniaturization of various communication terminals and the widespread use of wireless communication technology, it has become possible to make information devices portable such as mobile phones and portable communication personal computers.

In such a portable terminal, the power source for operating the device is often a battery, and in order to prolong the operating time of the device, the power of the function in the idle state is turned off. Power management is performed by lowering the operating clock frequency to reduce power consumption. These functions are generally known as a suspend function and a standby function.

When such a power management function is operating, the processing capacity of the device is often reduced or incapable of processing as compared with the normal device on state. When a communication request is generated from the device, it is difficult to perform a process that can sufficiently meet the request.

Therefore, when the power management function operates and the processing capacity is lower than usual, when the communication request is detected, the power supply of the apparatus is fully turned on and the processing is continued thereafter. That is, in the prior art, when the portable terminal detects a communication request (for example, the ring indicator [RI] of the modem), the power of the device is immediately turned on fully and the device processing capacity is maximized to meet the communication request. Naturally, when the power supply of the device is in the full-on state, the amount of battery consumption increases correspondingly, and as a result, the operating time of the device is shortened.

[0007]

If these communication requests are useful, the decrease in operating time due to the increase in battery consumption for that purpose is unavoidable. However, if there are many miscommunications such as a wrong phone call and intentional mischief communication, the battery is consumed, and when the operation of the device becomes necessary, the device cannot operate due to insufficient power. There is a risk.

According to the prior art, when the communication request is detected, the device is indiscriminately brought into the full-on state, so that the unnecessary battery power may be wasted for unnecessary communication (junk communication). Then, when the operation of the device becomes necessary, there is a problem that the remaining battery level is low and it is impossible to execute a satisfactory process.

According to the present invention, in order to avoid the wasteful consumption of the battery due to such unnecessary communication as much as possible, the communication I on the transmission side is performed.
The purpose of this invention is to solve the above-mentioned problems by determining whether or not the communication request can be received by setting D, the caller identification address, the caller's voice print, and the time limit for incoming call.

Notice. The power supply unit 5 turns on an appropriate power source in accordance with this,
The system such as the control unit 21 is started up. After that, the control unit 21 starts communication and starts necessary processing.

In the present embodiment, when the main body device 6 shown in FIG. 1 is operating, whether or not to use the automatic power-on restraint function is determined by the automatic power-on restraint setting processing unit 7 and whether the incoming call is permitted or prohibited by the communication ID. Whether or not to perform, whether to permit / prohibit the incoming call based on the identification address of the other party, whether to permit / prohibit the incoming call by the voice recognition of the other party, whether to perform the incoming / permit depending on the time of the communication request It can be set selectively with a command. Corresponding to these items 1 to 3, a flag indicating valid / invalid is provided in the determination information storage unit 2.

Further, when the incoming / outgoing call is permitted / prohibited by the communication ID, the communication ID as the target is the judgment information storage unit 2.

The automatic power-on suppression setting processing unit 7 performs setting processing and setting cancellation processing of these pieces of information.

3 to 7 are process flowcharts in the embodiment of the present invention. When the communication unit 4 detects a communication request from the outside (for example, in the case of a telephone line, the incoming signal corresponds to this) (S1 in FIG. 3), it notifies the power supply control unit 1 of it. The power supply controller 1 performs the following processing.

The power supply control unit 1 does not immediately turn on all the power supplies of the system, but first determines whether or not the automatic power-on suppression function is effective (S2 in FIG. 3). That is, it is determined whether or not the incoming call permission / prohibition is set.
If the automatic power-on suppression function is not valid here, the communication link is established (S12 in FIG. 3), and the system power is turned on by the power-on instruction to the power supply unit 5 (S7 in FIG. 3). That is, when the automatic power-on suppression function is not effective, the operation is the same as the conventional one.

If the automatic power-on suppression function is effective, it is determined whether or not the power-on is permitted by the following various determination factors. First, it is determined whether or not the incoming call permission / prohibition is set by the communication ID determination (see FIG. 3).
S3). If set, steps S21 to S21 of FIG.
The process of S25 is executed. First, in response to an incoming call, a communication link is established (S21 in FIG. 4) and a communication ID is received (S22 in FIG. 4). The communication ID stored in the determination information storage unit 2 of the database 22 that should be permitted to communicate is read (S23 in FIG. 4), and the received communication ID and the read communication ID are compared and determined (S24 in FIG. 4). . If the received communication ID is valid, the process proceeds to step S4 in FIG.
If it is an invalid reception communication ID, the communication is ended (S25 in FIG. 4) and the power is not turned on.

Next, it is judged whether or not incoming permission / prohibition is set by judging the identification address (for example, the telephone number of the calling side) (S4 in FIG. 3). If set, the processes of steps S31 to S36 of FIG. 5 are executed. First,
It is determined whether the communication link has been established (S3 in FIG. 5).
1) If not established, a communication link is established in response to an incoming call (S32 in FIG. 5). Then, the identification address of the other party is received (S33 of FIG. 5), the identification address to be permitted for communication stored in the determination information storage unit 2 of the database 22 is read (S34 of FIG. 5), and the reception identification address is received. Is compared with the read identification address (Fig. 5).
S35). As a result of the comparison, if the received identification address is valid (incoming call possible), the process proceeds to step S5 in FIG. If it is an invalid (unable to receive) reception identification address, the communication is terminated (S36 in FIG. 5) and the power is not turned on.

Next, it is judged whether or not the incoming call permission / prohibition is set by the judgment of the voice print (the kind of the voice of the calling side, the secret word, etc.) (S5 in FIG. 3). If set,
The processing of steps S41 to S46 of FIG. 6 is executed. First, it is determined whether the communication link has been established (S in FIG. 6).
41), if not established, a communication link is established in response to an incoming call (S42 in FIG. 6). After that, the voice of the other party is confirmed and the voice print is analyzed (S43 in FIG. 6). And
The voice print data to be permitted for communication stored in the determination information storage unit 2 of the database 22 is read (S4 in FIG. 6).
4), the received analysis result of the voice print and the read voice print data are compared and determined (S45 of FIG. 6). If the voice print is valid, the process proceeds to step S6 in FIG. If the voiceprint is invalid, the communication is ended (S46 in FIG. 6) and the power is not turned on.

Next, it is judged whether or not the incoming call permission / prohibition is set by the time designation (time zone for permitting or prohibiting the incoming call) (S6 in FIG. 3). If set, the processes of steps S51 to S55 shown in FIG. 7 are executed. First, the current time is read from the timer (S5 in FIG. 7).
1), read the incoming call prohibition time zone information stored in the determination information storage unit 2 of the database 22 (S5 in FIG. 7).
2) Before communication, it is determined whether or not the current time is a time period during which communication is permitted (S53 in FIG. 7). As a result, in the permitted time zone, it is determined whether or not the communication link has been established (S54 in FIG. 7), and the communication link is established only when it is not established (S55 in FIG. 7). Then, it progresses to step S7 of FIG. If the current time is a time period during which communication is not permitted, it is determined whether or not a communication link has been established (S56 in FIG. 7). If established, the link is released and communication ends (S57 in FIG. 7). ), The power is not turned on. Then, the process returns to step S1 in FIG. If it has not been established, nothing is done and the process returns to step S1 in FIG.

When the communication is permitted by the above determination processing, the power-on / start-up control unit 15 of the communication control unit 1
Instructs the power-on unit 16 of the power supply unit 5 to power on the main body device 6 including the control unit 21 and the like (S7 in FIG. 3). In response to this, the power supply unit 5 performs power-on. To do.
At this point, the control unit 21 becomes operable and executes subsequent communication (S8 in FIG. 3).

After the communication processing is completed (S9 in FIG. 3),
If the power management function of the power supply controller 1 is valid (S10 in FIG. 3), the power down mode is entered (see FIG. 3).
S11) and reduce the power consumption of the device.

Therefore, each of these means makes it possible to avoid turning on the power of the control unit 21 or the like in response to an unnecessary communication request. As a result, it is possible to prevent wasteful use of the power source (particularly the battery), and it is possible to extend the effective operating time of the device.
