Device processed.
Background technology
In recent years, such as notebook computer, desktop computer, tablet computer (PAD), mobile phone, multimedia
The electronic equipment of device, personal digital assistant (PDA) etc is more universal.Currently, electronic equipment supports wireless communication function mostly,
For being carried out with the other equipment of such as base station, access point or peer device etc by using different Wireless Access Standards
It communicates and transmits various data.
When electronic equipment is when carrying out wireless communication, its transmission power in up channel due to various reasons (for example,
When using a variety of Wireless Access Standard simultaneous transmission data) and can become bigger, may be more than that electromagnetic wave energy absorbs
Than the limitation of (SAR).Health for the user of electronic equipment considers that this is clearly to be not intended to occur for a long time.
In order to reduce the radiation (SAR value) to user, electronic equipment can be suitably reduced using back-off technology
Transmission power in up channel.In general, after executing back-off, the transmission power of electronic equipment can get lower than
Allow the maximum value of transmission power specified in third generation partnership project (3GPP) agreement.For example, in WCDMA agreements, institute
The maximum transmission power of the up channel of permission is 24dBm, however, after executing power and retracting, may become only having
22dBm。

The channel of call request and cell update request etc., so the place very weak in signal, if random access channel power by
Limitation will then cause communication percent of call completed to substantially reduce.
For this purpose, proposing a solution in the prior art, i.e., it is arranged on the application processor of electronic equipment (AP)
Two states about wireless communication：Under standby (IDLE) state, AP notifies communication processor (BP) without back-off
Operation, to obtain preferably communication percent of call completed；And under service connection success (CONNECTED) state, AP notifies BP to institute
There is up channel to call back-off operation, to reduce the radiation to user.It, can be in the health of user by doing so
It is obtained in terms of aspect and communication percent of call completed certain balanced.
However, the solution still has certain defect.For example, if electronic equipment occurs suddenly in communication process
Communication disruption, AP still believe that electronic equipment is in CONNECTED states due to that can not learn the communication disruption immediately, to
Continue notice BP to call back-off.At this moment, since electronic equipment needs to re-establish communication by random access channel
Connection, but random access channel power is still limited, so can cause to communicate percent of call completed reduction.Until BP works as to AP notices
Until preceding state has been changed to IDLE state, which is just notified that BP stops executing back-off, to compared with high emission work(
The random access channel of rate establishes communication connection to reattempt to.Thus, it is apparent that switch speed will be caused slowly (it is generally necessary to 1-
2 seconds), and for can not more be handled situations such as unexpected call drop in direct-cut operation or communication process.

It will be described in detail with reference to the accompanying drawings each embodiment according to the present invention.Here it is to be noted that it in the accompanying drawings,
It assigns identical reference numeral to the substantially component part with same or like structure and function, and will omit about it
Repeated description.
First, Poewr control method according to the ... of the embodiment of the present invention will be described with reference to Figure 1.
Fig. 1 illustrates Poewr control methods according to the ... of the embodiment of the present invention.
The illustrated Poewr control methods of Fig. 1 are applied to an electronic equipment.For example, the electronic equipment can be set with other
It is standby to carry out wireless communication, to transmit various data, for example, control signaling, business datum etc..
In order to enable user can be by the electronic equipment come (such as, base station, access point or equity are set with other equipment
It is standby) it carries out wireless communication, wireless communication device can be integrated in the electronic equipment.Pass through the wireless communication device, institute
Data can be received in a communication channel from other equipment by stating electronic equipment, and be set to other in another communication channel
Standby transmission data.
For example, when the electronic equipment as terminal device and with as service node base station or access point communicated
When, the channel from service node to electronic equipment can be known as to downlink, and will be from electronic equipment to service node
Channel is known as uplink.
In order to complete different functions, usually, downlink and uplink all include respectively many different letters
Road may be respectively used for transmitting various types of other control signaling, business datum etc. between electronic equipment and service node.Example
Such as, uplink includes multiple up channels, that is to say, that electronic equipment can emit letter in different classes of up channel
Number.
It is injured caused by user using electronic equipment to reduce, back-off technology can be used.
Since in the case of down channel, electronic equipment is merely capable of passively receiving data, so usually, no
The transmission power by service node used in down channel can be actively controlled in electronic equipment side.Further, since such as
The service node of base station etc often distance using electronic equipment user farther out, so the reception radiation of electronic equipment is often very
It is low, too major injury will not be generally caused to user.
On the contrary, when electronic equipment is when carrying out wireless communication, its transmission power in up channel may be very
Greatly, consequently, it is possible to being more than the limitation of specific absorption rate (SAR).Therefore, for the health of the user of electronic equipment
Consider, can suitably reduce transmission power of the electronic equipment in up channel using back-off technology.
In order to describe Poewr control method according to the ... of the embodiment of the present invention, first, by the classification of clear up channel and work(
Energy.
For example, various up channels can be simply divided into control channel and Traffic Channel, control channel be used for from
Electronic equipment transmits various control signalings to service node, and Traffic Channel is various for being transmitted from electronic equipment to service node
Data-signal.In addition, according to specific control function, can also further by control channel be divided into connection establish channel and
Other control channels.Connection establishes channel for emitting the request signal for being used for establishing communication connection.For example, letter is established in the connection
Road can be random access channel, and effect is to apply for radio resource to base station to network request, call request, cell more to send
New request etc..Other control channels are for executing other control functions, for example, power adjustment, measurement data, Non-Access Stratum signaling
Deng.
Due among the various up channels of wireless communication technique, being restricted if connecting and establishing channel power,
In the weaker environment of signal of communication, it will cause communication percent of call completed to substantially reduce, so proposing in an embodiment of the present invention
A kind of Poewr control method can establish channel and other when carrying out power control to each up channel to connection
Up channel is distinguish so that establishes channel to connection by differently mode and other up channels carry out power and return
It moves back, minimum is reduced to which channel influence suffered in back-off operation is established in connection, to ensure that electronic equipment is outstanding
Communication percent of call completed.
In the following, will illustrate Poewr control method according to the ... of the embodiment of the present invention in a specific example, wherein assuming that should
Electronic equipment is mobile phone, which can carry out wireless communication with base station, to complete the communication function needed for user
(for example, online, voice or video communication etc.), and it is also supposed that it is random access channel that channel is established in the connection so that the shifting
Mobile phone can send the request that networks, call request and cell update request etc. to base station in random access channel, in realization
State communication function.
However, it is necessary to explanation, the invention is not limited thereto.The electronic equipment can be any kind of electronic equipment,
It includes but not limited to：Notebook computer, tablet computer, mobile phone, multimedia player, personal digital assistant etc..It should
It can also be other kinds of uplink control channel or reverse link traffic channel that channel is established in connection.Further, it is also possible to will be according to this
The Poewr control method of inventive embodiments is applied to any other processing in electronic equipment.
As illustrated in figure 1, the Poewr control method includes：
In step s 110, transmission power control signal is obtained.
It, can in order to reduce radiation (SAR value) of the transmission power caused by electronic equipment (for example, mobile phone) to user
Transmission power of the electronic equipment in up channel is suitably reduced to use power back off technique.
Back-off technology is a kind of technology, by suitably reducing transmission power of the electronic equipment in up channel
(for example, reducing the transmission power of electronic equipment to allow transmission power most less than specified in wireless communication standard protocol
Big value), to mitigate radiation effect of the electronic equipment to user.
In one example, can back-off operation be executed to the up channel of electronic equipment always, so as to will be electric
Sub- equipment the radiation level of user is always remained as it is minimum, to farthest ensure user health.However, if this
Sample is done, it is likely that leads to the place very weak in signal, the control of required transmission when electronic equipment is communicated with other equipment
Signaling processed, the power of business datum are smaller, so as to cause decoding error, and ultimately cause communication abnormality.
Therefore, in order to obtain good equilibrium in the health for ensureing user and realization two aspects of normal communication,
In another example, back-off operation can be triggered based on a transmission power control signal.
In the first case, which can artificially be given birth to by user by operating electronic equipment
At.
For example, after the electricity for finding current mobile phone reduces, mobile phone generates human body excessively high in order to prevent
Radiation, user can be by manually keying in instruction or the modes such as actions menu come in electricity on the input unit of electronic equipment
The transmission power control signal is generated in sub- equipment.
In a second situation, which can also be obtained by being received from other equipment.
In the third case, which can also be automatically generated by electronic equipment.
For example, it may be determined that the first distance between the electronic equipment and the user of the electronic equipment, and root
The transmission power control signal is generated according to first distance.
Specifically, currently, being equipped with distance in many electronic equipments (for example, mobile phone or tablet computer etc.)
Sensor (for example, CapSensor sensors), the distance for detection human body apart from electronic equipment.Usually, which passes
Sensor can be various types of proximity sensors, such as, inductance type transducer, capacitance type sensor, hall sensor, light
Electric-type sensor, pyroelectric sensor, linear proximity sensor etc..
Thus, it is possible to detect electronic equipment and user's body by the range sensor equipped in the electronic device first
The distance between.It is then possible to further judge the relationship between detected distance and a specific threshold.When the distance is more than
When the specific threshold, it is believed that electronic equipment and user distance farther out, therefore, it may not be necessary to electronic equipment in up channel
Transmission power is controlled.On the contrary, when the distance is less than or equal to the specific threshold, it is believed that electronic equipment and user distance
It is relatively close, therefore, transmission power control signal can be generated, to be controlled to transmission power of the electronic equipment in up channel
System.
Further, it is also possible to further by the devices such as other sensors (for example, sphygmomanometer, blood glucose meter, electrocardiograph) come
The physical condition of user is judged, and in the case where user's body health degree is inherently poor, by above-mentioned specific threshold
Be selected as a bigger distance value so that electronic equipment and user distance farther out in the case of, begin to set in electronics
Back-off operation is carried out to up channel in standby.Alternatively, it can also judge the bad situation of user's body health degree
Under, directly generate the transmission power control signal.
In the step s 120, the channel category for the up channel for emitting signal in the electronic equipment is determined.
After obtaining transmission power control signal, in order to be subject to area when carrying out power control to different up channels
Point, so that executing back-off to these up channels by differently mode, it may be determined that in the electronic equipment
Emitting the channel category of the up channel of signal.
Herein, in order to ensure good communication percent of call completed, it is desirable to being used to establish the request communicated to connect for emitting
The connection of signal establishes channel (for example, for sending the random access of the request that networks, call request and cell update request etc.
Channel) execute the back-off different from other up channels so that it establishes channel for connection and ensures transmitting work(as high as possible
Rate.
For this purpose, for example, the up channel for emitting signal in the electronic equipment can be identified, and described in judging
Whether up channel is that channel is established in connection, and the connection establishes channel for emitting the request for being used to establish communication connection letter
Number.
Specifically, in different wireless communications modes (for example, global system for mobile communications (GSM), wideband code division multiple access
(WCDMA), long term evolution-frequency division duplex (LTE-FDD) etc.) in, different channel marks can be passed through when emitting signal
The channel informations such as knowledge, preamble are come to judge current electronic device on earth be to carry out transmitting operation in which up channel.
That is, a decision logic can be added in the radio frequency transmitter circuitry of electronic equipment, it is current to judge
Emitting the channel category of the up channel of signal, and is determining whether the up channel is that channel is established in connection.
In step s 130, it is operated according to the channel category to execute different back-offs to the up channel.
It, can be to connection after the channel category for determining the up channel for emitting signal in the electronic equipment
It establishes channel and other up channels is distinguish so that channel is established to connection by differently mode and other uplinks are believed
Road carries out back-off, to while mitigating radiation effect of the electronic equipment to user, ensure that electronic equipment still can
Obtain outstanding communication percent of call completed.
For example, when judge the up channel be it is described connection establish channel when, by the first back-off value come pair
The connection establishes channel and executes back-off operation, and is that channel is established in the connection when judging the up channel not
When, back-off operation is executed to the up channel by the second back-off value, wherein the first back-off value
Less than the second back-off value.
In one example, channel can be established to connection by different back-off values and other up channels is held
Row back-off operates.For example, connection can be made to establish the performance number of channel (for example, random access channel) rollback 1dB, and
So that other up channels other than channel is established in connection are (for example, may include other control channels and all industry
Be engaged in channel) rollback 2dB performance number.
In the second example, channel can not also be established to connection and executes back-off operation, and only to other uplinks
Channel executes back-off operation.For example, can be only so that other up channels other than channel is established in connection retract
The performance number of 2dB, that is to say, that be for establishing the first back-off value that channel execution back-off operates to the connection
Zero.
In addition, it is more preferable balanced in order to be obtained between user's health and communication percent of call completed, it can also be adaptively adjusted
Back-off value for establishing channel and other up channels progress back-off to connection.
For example, in this step S130, can continue to determine the electronic equipment and the electronic equipment user it
Between the first distance, and channel and other up channels are established for connecting to be individually determined according to first distance
Back-off value.
Specifically, the first back-off value and the second back-off value can with the electronic equipment with it is described
The first distance between the user of electronic equipment is inversely proportional.That is, electronic equipment is closer with user's distance, can incite somebody to action
The radiant power of up channel reduces more, and electronic equipment is remoter with user's distance, can be by the radiation of up channel
Power reduces fewer.It is to be noted, however, that no matter to the first back-off value and the second back-off value
Carry out how value, be required for ensureing that the first back-off value is less than the second back-off value.
It can be seen that using Poewr control method according to the ... of the embodiment of the present invention, it can be automatically or by user's hand
