Description
Technical field
The present invention relates to field of computer technology, more specifically, the present invention relates to a kind of Poewr control method and output control device.
Background technology
In recent years, the electronic equipment such as notebook, desktop computer, panel computer (PAD), mobile phone, multimedia player, personal digital assistant (PDA) is universal all the more.At present, the most support of wireless communication function of electronic equipment, for communicating and transmit various data by using different Wireless Access Standards with other equipment such as base station, access point or peer device.
When electronic equipment is in the time carrying out radio communication, its transmitting power in up channel due to a variety of causes (for example, in the time using multiple Wireless Access Standard to transmit data simultaneously) and can become larger, may exceed the restriction of specific absorption rate (SAR).Health for the user of electronic equipment considers, this is obviously not wish long-term appearance.
In order to reduce the radiation (SAR value) to user, can suitably reduce the transmitting power of electronic equipment in up channel by back-off technology.Conventionally,, after carrying out back-off, the transmitting power of electronic equipment can become the maximum lower than the permission transmitting power specifying in third generation partner program (3GPP) agreement.For example, in WCDMA agreement, the maximum transmission power of the up channel allowing is 24dBm, but after carrying out power rollback, it may become and only has 22dBm.
At present, in the time carrying out back-off operation, the transmitting power of all up channels all can be subject to back-off impact.But, due among the various up channels of wireless communication technology, Random Access Channel is the channel for sending networking request, call request and cell update request etc., so in the very weak place of signal, if Random Access Channel power is restricted, the call completing rate that will cause communicating by letter reduces greatly.
For this reason, a solution has been proposed in prior art, at the application processor (AP) of electronic equipment, two states about radio communication are above set: under standby (IDLE) state, AP notice communication processor (BP) does not carry out back-off operation, to obtain better communication call completing rate; And under service connection success (CONNECTED) state, AP notice BP calls back-off operation to all up channels, to reduce the radiation to user.By so doing, can aspect user healthy, obtain certain balanced with the call completing rate aspect of communicating by letter.
But still there is certain defect in this solution.For example, if communication disruption appears suddenly in electronic equipment in communication process, AP still thinks that owing to learning immediately this communication disruption electronic equipment is in CONNECTED state, thereby notice BP is continued to call back-off.At this moment, because electronic equipment need to re-establish communication connection by Random Access Channel, but Random Access Channel power is still limited, so the call completing rate that can cause communicating by letter reduces.Until BP has changed into IDLE state to AP notice current state, this AP just can notify BP to stop carrying out back-off, thereby again attempts establishing a communications link with the Random Access Channel of high transmit power.Like this, obviously will cause slowly (conventionally need 1-2 second) of switch speed, and in direct-cut operation or communication process suddenly the situation such as call drop more cannot process.

Embodiment
Describe in detail with reference to the accompanying drawings according to each embodiment of the present invention.Here, it should be noted that in the accompanying drawings, identical Reference numeral is given and substantially had part identical or similar structures and function, and will omit being repeated in this description about them.
First, with reference to Fig. 1, the Poewr control method according to the embodiment of the present invention is described.
Fig. 1 illustrates the Poewr control method according to the embodiment of the present invention.
The illustrated Poewr control method of Fig. 1 is applied to an electronic equipment.For example, described electronic equipment can carry out radio communication with other equipment, to transmit various data, for example, control signal, business datum etc.
For make user can by this electronic equipment come with other equipment (such as, base station, access point or peer device) carry out radio communication, in this electronic equipment, can be integrated with radio communication device.By described radio communication device, described electronic equipment can be from other equipment receiving datas in a communication channel, and in another communication channel to other equipment transmission datas.
For example, in the time that described electronic equipment communicates as terminal equipment and with base station as service node or access point, channel from service node to electronic equipment can be called to down link, and the channel from electronic equipment to service node is called to up link.
In order to complete different functions, as a rule, down link and up link all comprise many different channels separately, and it can be respectively used to transmit various types of other control signal, business datum etc. between electronic equipment and service node.For example, up link comprises multiple up channels, that is to say, electronic equipment can transmit in different classes of up channel.
In order to reduce the injury that uses electronic equipment to cause user, can use back-off technology.
Due to the down channel in the situation that, electronic equipment only can receive data passively, so as a rule, can not control on one's own initiative the transmitting power being used by service node in down channel in electronic equipment side.In addition,, because the service node such as base station is often far away apart from using the user of electronic equipment, so the receiver radiation of electronic equipment is often very low, generally can not cause too major injury to user.
On the contrary, when electronic equipment is in the time carrying out radio communication, its transmitting power in up channel may be very large, thereby may exceed the restriction of specific absorption rate (SAR).Therefore, consider for the user's of electronic equipment health, can suitably reduce the transmitting power of electronic equipment in up channel by back-off technology.
In order to describe the Poewr control method according to the embodiment of the present invention, first, by the classification of clear and definite up channel and function.
For example, various up channels can be divided into control channel and Traffic Channel simply, control channel is for transmit various control signals from electronic equipment to service node, and Traffic Channel is for transmitting various data-signals from electronic equipment to service node.In addition,, according to concrete control function, can also further control channel be divided into connect and set up channel and other control channels.Connect and set up channel for launching the request signal for establishing a communications link.For example, it can be Random Access Channel that channel is set up in this connection, and its effect is to send networking request, call request, cell update request etc. to base station application Radio Resource.Other control channels are used for carrying out other and control function, for example, and power adjustment, measurement data, Non-Access Stratum signaling etc.
Due among the various up channels of wireless communication technology, if connection is set up channel power and is restricted, in the weak environment of signal of communication, the call completing rate that will cause communicating by letter reduces greatly, so proposed in an embodiment of the present invention a kind of Poewr control method, it is in the time carrying out power control to each up channel, can set up channel to connection is distinguished with other up channels, make to set up channel and other up channels carry out back-off by mode differently to connecting, thereby connection is set up to channel suffered impact in back-off operation and reduce to minimum, to ensure the outstanding communication call completing rate of electronic equipment.
Below, to in an instantiation, illustrate according to the Poewr control method of the embodiment of the present invention, wherein, suppose that this electronic equipment is mobile phone, this mobile phone can carry out radio communication with base station, with the required communication function of completing user (for example, online, voice or video communication etc.), and suppose that it is Random Access Channel that channel is set up in this connection, make this mobile phone to send networking request, call request and cell update request etc. to base station in Random Access Channel, to realize above-mentioned communication function.
But, it should be noted that, the invention is not restricted to this.This electronic equipment can be the electronic equipment of any type, and it includes but not limited to: notebook, panel computer, mobile phone, multimedia player, personal digital assistant etc.Ascending control channel or the reverse link traffic channel that channel can be also other types set up in this connection.In addition, can also any other processing in electronic equipment will be applied to according to the Poewr control method of the embodiment of the present invention.
As illustrated in figure 1, described Poewr control method comprises:
In step S110, obtain transmitting power control signal.
For example, in order to reduce the radiation (SAR value) to user of transmitting power that electronic equipment (, mobile phone) produces, can suitably reduce the transmitting power of electronic equipment in up channel by back-off technology.
Back-off technology is a kind of technology, it for example, by (suitably reducing the transmitting power of electronic equipment in up channel, the transmitting power of electronic equipment is reduced lower than the maximum of the permission transmitting power specifying in wireless communication standard protocol), alleviate the radiation effect of electronic equipment to user.
In one example, can be all the time the up channel of electronic equipment be carried out to back-off operation, so as electronic equipment to be remained user's radiation level always minimum, thereby farthest ensure user's health.But, if done like this, likely causing the place very weak at signal, when electronic equipment and other equipment communicate, the power of the control signal of required transmission, business datum is smaller, thereby causes decoding error, and finally causes communication abnormality.
Therefore,, in order to obtain good equilibrium with realizing communicating by letter normally aspect two in the health that ensures user, in another example, can trigger back-off operation based on a transmitting power control signal.
In the first situation, this transmitting power control signal can be generated by operating electronic equipment artificially by user.
For example, after the electric weight of finding current mobile phone reduces, in order to prevent that mobile phone from producing too high radiation to human body, user can generate this transmitting power control signal by manually key in the mode such as instruction or actions menu on the input unit of electronic equipment in electronic equipment.
In the second situation, this transmitting power control signal also can be by receiving to obtain from other equipment.
In the 3rd situation, this transmitting power control signal can also automatically be generated by electronic equipment.
For example, can determine the first distance between described electronic equipment and the user of described electronic equipment, and generate described transmitting power control signal according to described the first distance.
Particularly, at present, for example, in a lot of electronic equipments (, mobile phone or panel computer etc.), be all equipped with range sensor (for example, CapSensor transducer), the distance for human body apart from electronic equipment.Usually, this range sensor can be various types of proximity transducers, such as, inductance type transducer, capacitance type sensor, hall sensor, electro-optical pickoff, pyroelectricity formula transducer, linear proximity transducer etc.
Thus, can first carry out the distance between detected electrons equipment and user's body by the range sensor of equipping in electronic equipment.Then, can further judge the relation between detected distance and a specific threshold.In the time that this distance is greater than this specific threshold, think that electronic equipment and user distance are far away, therefore, can the transmitting power in up channel control electronic equipment.On the contrary, in the time that this distance is less than or equal to this specific threshold, think that electronic equipment and user distance are nearer, therefore, can generate transmitting power control signal, so that the transmitting power to electronic equipment in up channel is controlled.
In addition, can also be further by other transducers (for example, sphygmomanometer, blood glucose meter, electrocardiograph) etc. device judge user's health, and at user's body health degree itself with regard to poor in the situation that, above-mentioned specific threshold is chosen as to a larger distance value, make, just to start, in electronic equipment, up channel is carried out to back-off operation in the situation that far away in electronic equipment and user distance.Alternatively, also can, judging user's body health degree not good in the situation that, directly generate this transmitting power control signal.
In step S120, determine the channel classification of the up channel transmitting in described electronic equipment.
After obtaining transmitting power control signal, in order to be distinguished in the time that the up channel to different carries out power control, to make to come these up channels to carry out back-off by mode differently, can determine the channel classification of the up channel transmitting in described electronic equipment.
Here, in order to ensure good communication call completing rate, for example wish, to (setting up channel for the connection of launching the request signal for establishing a communications link, be used for sending the Random Access Channel of networking request, call request and cell update request etc.) carry out the back-off different from other up channels, make to set up the high as far as possible transmitting power of channel guarantee for connecting.
For this reason, for example, can be identified in the up channel transmitting in described electronic equipment, and judge whether described up channel is to connect to set up channel, and described connection is set up channel for launching the request signal for establishing a communications link.
Particularly, at different wireless communications modes (for example, global system for mobile communications (GSM), Wideband Code Division Multiple Access (WCDMA) (WCDMA), Long Term Evolution-Frequency Division Duplexing (FDD) (LTE-FDD) etc.) in, can be in the time transmitting, judging current electronic device by the different channel informations such as channel logo, preamble is in which up channel, to carry out firing operation on earth.
That is to say, can in the radio-frequency transmissions circuit of electronic equipment, add a decision logic, thereby judge the channel classification of the current up channel transmitting, and determine whether this up channel is to connect to set up channel.
In step S130, according to described channel classification, described up channel is carried out to different back-off operations.
Determine the channel classification of the up channel transmitting in described electronic equipment after, can set up channel to connection is distinguished with other up channels, make to set up channel and other up channels carry out back-off by mode differently to connecting, thereby alleviate electronic equipment to user's radiation effect in, ensure electronic equipment still can obtain outstanding communication call completing rate.
For example, that described connection is while setting up channel when judging described up channel, by the first back-off value, described connection is set up to channel and carry out back-off operation, and not that described connection is while setting up channel when judging described up channel, come described up channel to carry out back-off operation by the second back-off value, wherein, described the first back-off value is less than described the second back-off value.
In one example, can set up channel and the operation of other up channels execution back-off to connecting by different back-off values.For example, can make to connect and (for example set up channel, Random Access Channel) performance number of rollback 1dB, and make to set up the performance number of other up channels (for example, can comprise other control channel and all Traffic Channels) the rollback 2dB channel except connecting.
In the second example, also can not set up the operation of channel execution back-off to connecting, and only other up channels be carried out to back-offs operation.For example, can only make to set up except connection the performance number of other up channel rollbacks 2dB channel, that is to say, the first back-off value of carrying out back-off operation for described connection being set up to channel is zero.
In addition, better balanced in order to obtain between user's health and communication call completing rate, can also adjust adaptively the back-off value of carrying out back-off for connection is set up to channel and other up channels.
For example, can be in this step S130, continue to determine the first distance between described electronic equipment and the user of described electronic equipment, and be identified for respectively connecting according to described the first distance the back-off value of setting up channel and other up channels.
Particularly, described the first back-off value and described the second back-off value can and described electronic equipment and the user of described electronic equipment between first distance be inversely proportional to.That is to say, electronic equipment and user's distance are nearer, can the radiant power of up channel be reduced manyly, and electronic equipment and user's distance are far away, can the radiant power of up channel be reduced lesser.But, no matter it should be noted that how described the first back-off value and described the second back-off value carried out to value, all need to ensure that described the first back-off value is less than described the second back-off value.
As can be seen here, adopt according to the Poewr control method of the embodiment of the present invention, can be automatically or manually trigger for the back-off of the up channel of electronic equipment and operate by user, to make, according to described channel classification, described up channel is carried out to different back-off operations.Therefore, a kind of Poewr control method has been proposed in an embodiment of the present invention, it is in the time carrying out power control to each up channel, can set up channel to connection is distinguished with other up channels, make to set up channel and other up channels carry out back-off by mode differently to connecting, thereby ensureing user's health and realizing normal communication aspect two, to obtain good equilibrium.
