Mobile terminal, and method for controlling a maximum power of the mobile terminal

The present invention relates to the maximum output control of the mobile terminal, the invention relates to controlling the maximum output of the mobile terminal according to the call mode indicating how the call is made.

When talking to the other party using a mobile terminal is generally used in a position close to the head of the body, in which case there is a national and international standard for Specific Absorption Rate (SAR).

In this case, the specific absorption rate of electromagnetic waves means an energy ratio per unit mass absorbed by living tissue, and is expressed as 'mW / g' as a unit, and a standard measuring procedure is a portable wireless device used at a position close to the human head. Is being applied to.

Due to the limitation of the electromagnetic specific absorption rate specification, for example, in the case of a WCDMA terminal, the maximum power limit is fixed to about 24 dBm.

On the other hand, according to the development of various interface technologies in recent years, it is possible to use a mobile terminal away from the head of the body rather than necessarily using the mobile terminal in a position close to the head of the body when talking to the other party.

For example, a wired earphone jack may be coupled to a mobile terminal to make a call with the other party through a wired earphone, or a Bluetooth module may be mounted in the mobile terminal and a call may be made with a wireless earphone capable of Bluetooth communication. (Hereinafter, the mode of making a call in this manner will be referred to as an 'earphone call mode'). In addition, when it is difficult to make a call using a hand or when a user wants to make a call with several people, the call may be made using the mobile terminal as a speakerphone (hereinafter referred to as a speakerphone call mode. Will be called).

 By the way, in the earphone call mode or speakerphone call mode as described above, although the mobile terminal is not located close to the head of the body, the above-mentioned electromagnetic wave specific absorption rate standards are applied to improve the output of the mobile terminal. Has become a constraint specification.

Technical problem to be solved by the present invention is not limited to the maximum output limit value when the mobile terminal is located near the head of the body when the mobile terminal is not located close to the head of the body, the output of the mobile terminal To improve.

Hereinafter, a method of controlling the maximum output of the mobile terminal according to an embodiment of the present invention will be described in detail.

1 is a flowchart illustrating a method of controlling a maximum output of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 1, first, after the power of the mobile terminal is turned on (S100), when a call reception or a call origination of the mobile terminal occurs, the current communication mode is used in a position close to the head of the human body ( Hereinafter, it will be referred to as "human contact call mode") (S110). Of course, the call mode may be determined before the incoming call or the call origination after the mobile terminal is turned on, but the call mode is determined by the user's will (for example, the earphone is removed) until the incoming call or the call is made. Since may be changed, it is preferable to determine the call mode after the call incoming or outgoing call occurs.

If the current call mode is the body contact call mode, the maximum output of the mobile terminal is adjusted to a preset maximum output limit value according to the standard for the specific absorption rate of electromagnetic waves (S120).

However, if the current call mode is not the body contact call mode, it is determined whether the current call mode is a call mode which is not used at a position close to the head of the human body (hereinafter referred to as a 'human non-contact call mode'). (S130).

Examples of the non-contact communication mode of the human body include the earphone call mode or the speakerphone call mode described above.

In addition, a call type of the mobile terminal, that is, video call, message transmission, data transmission, and the like may also be included in the non-contact communication mode.

If the current call mode is the non-contact communication mode, the maximum output is adjusted to represent the maximum output of the mobile terminal by maximizing the output of the high frequency circuit modules constituting the mobile terminal (S140). That is, when the call mode is the non-contact communication mode, the mobile phone adjusts to the maximum output value that can be represented by the mobile terminal without conforming to the specification for the specific absorption rate of the electromagnetic wave.

On the other hand, if it is set to the maximum output limit value in accordance with the specification for the current electromagnetic wave specific absorption rate, if it is determined that the human body contact call mode in step S110 to maintain the same as the current maximum output limit value set in step S120, step S110 And if it is determined in the non-contact communication mode human body through the step S130 is adjusted to the maximum output limit value that can be represented by the mobile terminal without following the specification for the electromagnetic wave specific absorption rate in step S140.

Similarly, when the current state is set to the maximum output limit value according to the non-contact communication mode, if it is determined in step S110 that the body contact call mode is adjusted to the maximum output limit value according to the specification for the electromagnetic wave absorptivity in step S120 and If it is determined that the human body is in the non-contact communication mode through steps S110 and S130, the maximum output value currently set in step S140 is maintained.

Meanwhile, in FIG. 1, it is determined that the human body contact mode is first and then the human body non-contact mode, but is not limited thereto. For example, it may first determine whether the body is in a non-contact communication mode, otherwise it may be determined whether the body is in a human-contact communication mode. Instead, the communication mode is not sequentially determined as shown in FIG. 1, but various events occurring in the mobile terminal are detected. It is also possible to determine the call mode.

In addition, the timing of detecting and determining the current call mode is periodically performed at a predetermined time interval after the power of the mobile terminal is turned on, or more preferably, after a call reception or call origination occurs after the power of the mobile terminal is turned on. You can also determine the call mode.

As another embodiment of detecting and determining a current call mode, the present invention may be performed based on an event for determining a call mode by detecting a specific event (eg, detecting transmission / reception of communication data) occurring in a mobile terminal.

When the current call mode is detected based on an event, it is preferable to periodically detect the current call mode at a predetermined time interval from a time when a specific event occurs. This is because the caller may change the communication method from the non-contact communication mode to the non-contact communication mode or change the communication method from the non-contact communication mode to the human contact communication mode during the call in the human-contact communication mode.

In addition, in FIG. 1, when the current call mode is different from the previous call mode, it is necessary to adjust the new maximum output limit value. In this case, the mobile terminal may automatically adjust the maximum output limit value according to the current call mode. When changing modes, the caller may manually adjust the maximum output limit value according to the current call mode.

2 is a block diagram showing the configuration of a mobile terminal according to an embodiment of the present invention. If the user is a terminal such as a mobile phone that allows a user to make a call through a communication network, all of the mobile terminal 200 according to the present invention. May be included.

Referring to FIG. 2, the mobile terminal 200 according to the present invention includes a call mode identification module 210, a maximum output adjustment module 220, an input / output module 230, a storage module 240, and a control module 250. Include.

The call mode identification module 210 detects and identifies which call mode state when a user makes a call with a counterpart using a mobile terminal.

That is, it is identified whether the current call mode is the body contact call mode or the non-contact call mode. The step S110 or the step S130 illustrated in FIG. 1 may be performed by the call mode identification module 210.

A method for identifying whether the current call mode is a non-contact call mode, for example, by detecting that a function of a Bluetooth module or speakerphone mounted in a mobile terminal is activated or an earphone jack is connected, the current call mode is called a non-contact call mode. You can judge. In particular, the wired earphone jack may be identified on a general purpose input / output port mounted on the mobile terminal.

As another example of identifying whether the current call mode is a non-contact call mode, since the call type of the mobile terminal is spaced apart from the head of the human body when the call type is a video call, message transmission, data transmission or the like, such a call type In one case, it is determined that the current call mode is a non-contact call mode.

On the other hand, call types can be distinguished in a call manager layer that provides an overall function of a call to an application. For example, a call type can be identified within a data structure in which the call type is defined as 'call_type'. Call types can be distinguished by defining variables representing 'CALL_TYPE_VT' and variables representing messages, such as 'CALL_TYPE_SMS'. The maximum output coordination module 220 is determined by the call mode identification module 210. It provides the ability to adjust the corresponding maximum output according to the type of the current call mode identified.

For example, when it is determined that the current call mode is the body contact call mode, the maximum output adjustment module 220 adjusts the maximum output of the mobile terminal 200 according to the specification for the electromagnetic wave absorptivity, and the current call mode is When it is determined that the human body is in a non-contact communication mode, the maximum output limit is adjusted to the maximum output that the mobile terminal 200 can display without being limited by the standard for the electromagnetic wave absorptivity. That is, step S120 or step S140 shown in FIG. 1 is performed by the maximum output adjustment module 220.

In the non-contact communication mode, the maximum output of the mobile terminal 200 may be represented in consideration of characteristics of circuit elements or components constituting the mobile terminal 200. For example, in the case of PAM (Power Amplifier Mudule) conforming to 3GPP Power Class 3 specification, when the standard is applied to WCDMA terminal, the maximum output is fixed at about 24dBm, The maximum output of the mobile terminal can be improved from 28dBm to 28.5dBm.

When the input / output module 230 wants to manually adjust the maximum output of the mobile terminal 200 by the user, the user may query whether the maximum output is changed according to the change of the call mode, and whether the maximum output is changed from the user. Provides the ability to receive input.

In addition, the user may select or release a direct call mode through the input / output module 230.

If the maximum output of the mobile terminal 200 is automatically adjusted according to the call mode, the input / output module 230 visually displays the changed contents of the changed call mode and the corresponding maximum output to the user. Call alerts) or by acoustic means of delivery (eg, voice alerts).

The storage module 240 stores the maximum output information for the human body contact call mode and the human body contactless call mode.

In this case, the storage module 240 may include a cache, a read only memory (ROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), and an electrically erasable programmable ROM (EEPROM). And at least one of a nonvolatile memory device such as flash memory, a volatile memory device such as random access memory (RAM), and a storage medium such as a hard disk drive or a removable storage device. It may be implemented as above, but is not limited thereto.

The control module 250 provides a donation that is responsible for the communication and control between each of the components shown in FIG.
