Description
Technical field
The present invention relates to radio communication field.Or rather, the present invention relates to the technology of a kind of residue service time of the battery that is estimated as radio communication equipment power supply.Such equipment can be for example mobile phone, PDA (English " Personal Digital Assistant ", i.e. " personal digital assistant ") or any other portable terminal.
Background technology
Most of present mobile phones all have the function of the charge level of battery being informed its user.For example, one group of rule that this charge level is used on the call screen represents that the quantity of the rule or size reduce along with battery electric quantity.Therefore, when battery had just filled electricity, the user sees that all rules show on screen, then, make a call several or send several notes (i.e. " SMS ", the expression English " Short Message Service ", i.e. " short message service ") after, the quantity of the rule reduces, when having put electricity when battery, and rule complete obiteration.
A disadvantage of prior art is: the indication that this system offers the user often is too at random, and the residue continuous working period of battery is not informed the user a bit.In fact, often be that the rule of maximum quantity shows that for a long time then, after the once short telephone relation, the quantity of the rule reduces suddenly and sharp.Originally thought that its phone also has the very user of long duration before current conversation, finished once new conversation so catch sight of with can not or else emitting the power down risk.
The disadvantage that this user of order is very unhappy derives from being used for of adopting in the current mobile phone, and to assess the device of battery charge level too simple and crude.Especially, one of main disadvantage of prior art is: it can not the assessment apparatus battery in energy remaining, and can only assess ratio with respect to the dump energy of the maximum charge level of battery.
Yet, the maximum charge level meeting of battery, aging along with battery for example, and reduce.Therefore, if cell degradation, the user may see that many rules are presented on the screen, shows that battery it seems enough electric weight, but the Meteorological Services that in fact but can not consult message or use operator to provide owing to there are not enough duration.
Summary of the invention
The present invention is a purpose with the disadvantage of slowing down former method especially.
Or rather, an object of the present invention is to provide in a kind of estimating battery residue service time, reliable technique, and give one of user than the more accurate indication of prior art.
Especially, the purpose of this invention is to provide a kind of like this technology: this technology allow the user know which or which be the application that he can continue the radio communication equipment that uses according to the charge level of battery.
Another object of the present invention is: implement a kind of such technology, or even also reliable in cell degradation.
A further object of the invention: a kind of so simple and low technology of implementation cost is provided.
These purposes, as other purpose that will occur subsequently, all be that method by means of residue service time of a battery that is used to estimate radio communication equipment reaches, this method allows that one side guarantees at least one voice communications applications to guarantee at least one additional application on the other hand.
According to the present invention, this method has been considered the needed concrete energy of at least two available on described equipment different application, and described residue is adjusted according to the application that is used or planned to use service time.
Therefore, the present invention is based on charge level, the novel and creative method of an estimation radio communication equipment battery.In fact, the present invention proposes not only will consider the battery remaining power of a given time, also to consider the energy that different application consumed of equipment, whether can also use in the application that he can insert each thereby can indicate him, and how long can use to the user.
Therefore the present invention has constituted a tangible progress with respect to prior art; Prior art only indicates the percentage of battery electric quantity to the user, do not reflect the energy that in fact remains in the battery fully.
Therefore it provide a much important convenience concerning the user, allows that he manages his use to its phone or PDA according to the duration of real surplus better.
Advantageously, we have considered the feature that at least one represents described battery, to estimate the residue service time of radio communication equipment.
Best is that this method comprises a step of measuring the voltage of described battery.
This voltage has provided first indication about the dump energy of a certain given time battery.It is determined by the transducer of battery.
According to a favourable feature of the present invention, described tested voltage is weighted according to the operating temperature of described equipment.
In fact, ambient temperature is a parameter that makes that cell voltage changes, and therefore should be considered, to calculate energy remaining.
Best is that this method comprises step and step of storing the parameter of that at least one is derived out by described monitoring, as to represent described battery characteristic of a described battery of periodic monitoring.
In fact, be not that all battery is all identical.Although the standard that is provided by manufacturer is arranged, the discharge curve of two batteries of same type also may be different slightly when dispatching from the factory.So the monitoring battery that must be in operation, to allow reliable calculating to dump energy.
Advantageously, this method comprises a step of managing the evolution history of at least one parameter of representing described battery.
Therefore we considered the aging action of battery.
Best is, described (respectively) parameter is stored in the nonvolatile memory, for example EEPROM (English " EEPROM ") type or flash memory (Flash) type.
Even when radio communication equipment no longer was powered, for example under the situation that battery discharges fully, these parameters still had been stored therefore.
Best is that described parameter is the dump energy of described battery on a certain predetermined point on the discharge curve.
The discharge curve of battery is made of a series of straightways or horizontal line usually, and the public point of these line segments is easy to identification.For example, we can be stored in the energy (usually in advance know) of battery at these end points places in the static memory.
Advantageously, this method comprises a step that is stored in the described dump energy in the nonvolatile memory according to the aging conditions correction of described battery.
In fact, along with aging, the ability that battery keeps electric charge worse and worse, thereby its discharge curve is also developing.
Best is that by the dump energy of dump energy of relatively estimating and the described battery that measures, the aging conditions of described battery is evaluated.
Therefore, we use the error that the energy of estimating is measured to distinguish the aging conditions of battery, and therefrom extrapolate the corresponding differentiation of discharge curve.For example, if we notice that battery is almost empty, and this should be not empty according to calculating it, and we just reduce to be stored in the residual energy value for predetermined some point on the discharge curve in the nonvolatile memory.
Advantageously, we estimate arbitrarily the dump energy a bit on of described battery at described discharge curve according in the following data at least some:
That ■ is stored in is in the nonvolatile memory, the described dump energy at least one predetermined point of described discharge curve;
During the start-up time of at least one parts of the described radio communication equipment of ■;
The theory consumption of described at least one parts of the described equipment of ■.
Therefore, in that those are not known on the point of its energy in advance on the discharge curve, we have come the dump energy of counting cell at this point by the energy consumption of assessment since discharge curve stored goes up a bit.Energy consumption since a last known point is calculated with the form of the product of the theory consumption of start-up time of each parts of this mobile phone and each parts.
According to a favourable feature of the present invention, this method used one level and smooth described measure voltage and/or the function of energy.
Therefore we have become more meticulous the result of the algorithm of dump energy in the counting cell.
Best is that if remaining electric weight meets certain application-specific of use, this method comprises the step of a warning.
For example, if battery electric quantity is not enough for certain Video Applications, the user just is alerted no longer can use this program.
Advantageously, under the situation that described application implementation remote data loads, if be not enough to implement remote loading remaining time, if and/or the dump energy behind the described remote loading be lower than certain predetermined threshold value, we just do not authorize this remote loading so.
Therefore we avoided knowing that battery dump energy will not allow the remote loading of finishing a high energy consumption well, or no longer allow afterwards and use some application than low energy consumption, and for example voice call is used, the time carry out this remote loading.Threshold value can be set by network or radio communication equipment in advance, or selected by the user.
According to a favourable modification of the present invention, when using at least one minimum time of using in addition corresponding to a minimum voice call time and/or described equipment remaining time, this method bans use of or advises not using application.
Again, this minimum time can be selected according to its needs by the user, or is set by the network that phone or phone connected in advance.
Therefore we allow the user for example in case of emergency make a call last before battery discharges fully.The application of quilt priority can pre-determine, perhaps by the user according to its most frequent use should be used for select.
According to another favourable modification of the present invention, when remaining time corresponding to minimum voice call time once and/or when using the minimum time of Another application at least, this method is interrupted or the use of using is interrupted in suggestion.
This method thereby can implement a ratio and when using equipment, send out an intrusion that simple reminding short message is stronger.
Advantageously, this method has been considered the necessary transmission of power of a certain given time, especially according to described equipment and with base station that it is communicated by letter between distance.
In fact, for example, when mobile phone during further from the base station, the energy consumption during the voice call is higher, because the transmitting power of phone must be higher.
Best is, this method has comprised that produces a step that is sent to the message of the radio communication net that is connected with described equipment, and this message is used for described residue is informed described network service time.
Therefore we provide the possibility of the remaining time of knowing telephone cells to radio communication net.This message can be a specific message, it according to the communication protocol of equipment and network by standardization.
Best is that described message is sent by described radio communication equipment according to the request of described network.
Thereby the network challenge equipment time interval of a rule---for example according to---is to learn the remaining time of battery.
Best is, when described residue service time corresponding to the minimum voice call time and/or when using the minimum time of at least one other application, the described equipment of described network limits inserts application.
Thereby if this network is concluded deficiency remaining time of battery, it can be forbidden or limit mobile phone and insert some application.
Description of drawings
One reads the description to a kind of preferred forms and each accompanying drawing subsequently, and other characteristic of the present invention and advantage just will more clearly display, and this preferred forms provides as descriptive and nonrestrictive simple case.Accompanying drawing is as follows:
-Fig. 1 has showed a radio communication equipment and to the schematic diagram of the battery of its power supply;
-Fig. 2 has drawn the discharge curve of the battery among Fig. 1;
-Fig. 3 has described the exchange agreement about residue duration of the battery among Fig. 1 between radio communication equipment and the network.
Embodiment
General principle of the present invention based on: not only according to the dump energy in the battery, and the residue service time of coming estimating battery according to each energy consumption of using that radio communication equipment inserts.
We tell about the example of using radio communication equipment 1 of the present invention and associated batteries 2 corresponding to Fig. 1.
Battery 2 is contained in the machine box of equipment 1, and when equipment directly is not connected civil power when online, this battery provides the energy to equipment.
Equipment shown in Fig. 1 is a mobile phone.It can certainly be any other battery-powered radio communication equipment, for example PDA, laptop computer, or the like.We have also drawn an icon 3 on the screen of phone 1, this icon is represented the dump energy of battery 2 according to prior art.This icon 3 comprises one group of rule, when these rules all show, shows that the charge level of battery is in maximum.
Otherwise according to the present invention, each that can insert according to the user residue service time of phone 1 used the energy that consumes and calculated according to the knowledge to the discharge curve (drawing among Fig. 2) of battery 2.
The curve of Fig. 2 is represented the voltage V of the terminal place of battery 2 corresponding to time t.When battery had just filled electricity, its terminal voltage equaled V
MAXVoltage descends gradually then, passes through A, B, C, the D point of discharge curve successively.We will notice that the voltage at interdischarge interval battery 2 is not linear change.When mobile phone 1 is slowly discharging owing to use, can there be the stage of one section constant voltage on the discharge curve.
Some A on the curve among Fig. 2, B, C are first end points that constitutes each straightway of discharge curve, can recognize easily: battery is known in advance and be stored in the static memory of phone 1 in the dump energy of these points.
More accurate theory, when analyzing the discharge curve of battery for the first time, the dump energy at some A, B, C place is learnt from the specification that battery manufacturers provides.It just upgrades according to the monitoring that battery is connected discharge then, and the numerical value that monitors is stored, and the numerical value that provides of alternative manufacturer.
Otherwise the dump energy at some D place that is in the optional position on a certain section of discharge curve is then more difficult to be determined.In order to calculate it, we detect a C (it is the known point of closest approach D on the discharge curve), and the energy consumption of computing equipment 1 between a C and some D.
For this reason, we measure the voltage at the terminal place of battery 2 by battery sensor.We also consider the operating temperature of phone 1, and this temperature can make the change in voltage (in fact, knowing that temperature is one of criterion that stops battery charge) of battery 2.
If we order battery 2 at C dump energy is called E
C, battery 2 in a dump energy at D place is exactly:
E
D=E
CThe energy consumption that-C point is ordered to D
In order to calculate the energy consumption that mobile phone 1 is ordered to D from the C point, we are according to the starting time of the different parts of this mobile phone, and the theoretical energy consumption of each parts, for example the energy consumption of defined in the specification of this phone 1 that is provided by manufacturer.
Therefore, if from a C, user's remote loading two minutes file, three notes in 1 minute 30 seconds, have been sent out then, we calculate on the one hand owing to the remote loading that starts two minutes is used the energy that consumes, calculate on the other hand owing to sending the energy that note consumes, we deduct this energy consumption from the dump energy of a C, so that therefrom obtain a dump energy at D place.
Each uses the energy consumption that the energy that consumes comprises this application itself on the one hand, comprises that on the other hand this energy consumption depends on for example transmitting power of phone 1 owing to the caused energy consumption of telecommunications functions, and this transmitting power is relevant apart from the distance of base station with phone.
The starting time of different application can determine that accurately this clock is allowed minute from the real-time clock (RTC) RTC (English " Real Time Clock ") of mobile phone.
Therefore, the energy of A, B, C is allowed the energy at other each point place of calculating discharge curve.
Yet because battery is aging, the energy at some A, B, C place may in time and slightly change.Therefore, must in the cell degradation process, revise the numerical value that is stored in the memory.
For this reason, we detect the aging performance of battery from the error that estimated value is measured.If we have noticed that battery 2 is similar empty, and be not like this according to calculating, we just reduce to be stored in the E in eeprom memory or quickflashing (Flash) memory
A, E
B, E
CNumerical value, to obtain more realistic discharge curve.
After this, our corresponding diagram 3 is described the information exchange about remaining time of battery 2 between the radio communication net that phone 1 and its connects.
In a mark step of 5, the base station 4 near phone 1 sends a request to phone, to know the dump energy of battery 2.Equipment 1 is replied (6) with the form of a standardized messages, and this standardized messages comprises the identity information of equipment 1, and the dump energy numerical value of the battery 2 that calculates.
This standardized messages (6) is 3 grades of protocol messages, is RR (expression " radio resource ") layer under the GSM situation, and is RRC (expression " radio resource control ") layer under the UMTS situation.
It comprises head and one " body " of a legacy protocol, i.e. body, and this body has comprised the information with the remaining battery time correlation.
Can consider that two kinds are implemented modification.
Implement in the modification of the present invention first, phone 1 sends to base station 4 with the battery remaining power numerical value that calculates.In this case, the body of standardized messages 6 comprises a battery charge level indication, represents with mAh.For example, the body band of message 6 numerical value 0,1,2 or 3, and expression comprises the numerical value interval of battery remaining power: for example the charge level of numerical value 0 expression battery is lower than 10mAh, and numerical value 1 expression charge level is comprised between 10 to 20mAh, or the like.
So network according to the required concrete energy of application that each user can insert, is determined the residue service time that each is used from this dump energy.So if network-evaluated residue deficiency service time, it can determine limited subscriber to insert some application.It can also send a reminder message to the user, for example allows the user notice that battery dump energy can only allow that he carries out 8 minutes voice call or sends out 10 notes again.Thereby network can be forbidden the user and carry out the long and file remote loading of highly energy-consuming.
Implement in the modification of the present invention second, the own dump energy from the battery 2 that calculates of phone 1 calculates the residue service time of each program that the user can insert.
For example, known the energy that dump energy and each use per second and consume (according to the energy consumption of each element of phone 1 itself with according to by the caused energy consumption of telecommunications functions), phone 1 just calculates the possible service time of each voice call function, remote loading file, transmission note etc.
So it shows a message on screen, to inform the user.Sometimes, if the user has started one of application that can insert, phone 1 just shows a reminder message on screen, inform the interruption that is about to that may cause because the residue duration is not enough.
Second implement modification according to this, phone 1 is not only to the dump energy of online transmission battery 2, and sends the residue service time that it calculates.
So whether network can determine available application on the limited subscriber Access Network in view of these service times.
In this case, in the body of standardized messages 6 with information be the residue service time (for example, voice call time or possible transfer of data byte number) of the telephony feature of some.
We it is also conceivable that certainly and do not allow radio communication net get involved.So, whole calculating, and generate reminder message and possible mandate, forbid or interrupts the access of some application is all managed by mobile phone 1 fully.
