Abstract
The invention relates to a method for controlling at least one service performed in a radiocommunication device, ensuring at least two distinctive services. According to the invention, one such method comprises a stage for authorising the performance of one of said services if the energy consumed by said device during the performance of said service tallies with a criterion for managing the use of the energy of a battery pertaining to the device.
Description
Technical field
The present invention relates to radio communication field.Or rather, the present invention relates to a kind of technology of controlling the use of the miscellaneous service that the radio communication equipment user can insert, so that optimize management to the energy content of battery.This equipment can be for example mobile phone, PDA (English " PersonalDigital 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, this charge level represents that with one group of rule on the call screen 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 equipment of battery charge level too simple and crude.
In view of the faint residue duration of battery, this usually causes the user to be engaged in the operation that he can not finish.For example, the user may begin file of remote loading, and in view of the dump energy of battery, this file is proved too greatly and intactly remote loading.The user also may begin a telephone relation, but has to interrupt owing to electric energy is not enough at last.
This makes the user very unhappy: if he knows that he can not finish the application of a high energy consumption, perhaps he knows that he no longer includes enough electric energy before battery discharges fully and carries out last telephone relation, and he often will determine not carried out the application of these high energy consumptions so.
Yet, still do not exist any known technology to inform the application that he can also use in view of battery remaining power so far to the user.
In fact, according to prior art, people are the interior energy remaining of assessment apparatus battery not, and only assesses the ratio with respect to the dump energy of the maximum charge level of battery.
Yet, the maximum charge level meeting of battery---for example along with battery aging---and reducing.Therefore, if cell degradation, the user may see that many rules are presented on the screen, demonstrate battery and 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.
In addition, such certain situation is arranged: same radio communication equipment can insert two different networks, has different energy consumption characteristics.
Therefore, when the end of the year 2003, Europe started the UMTS network, will be set an interstage, during this interstage, radio communication equipment can be dual mode operated with GSM/UMTS.Yet, about the UMTS standard, found a main shortcoming, compare with the GSM/GPS system exactly, in same application (voice communication and low speed data transmission), UMTS caused energy consumption.According to mobile phone manufacturer according to a preliminary estimate, " stand-by time " of UMTS and " air time " almost are half of time of observed GSM, thereby make the duration of mobile phone on UMTS be a half.
As drawn among Fig. 5, the energy consumption peak value of UMTS, GSM, GPRS shows that the energy consumption of UMTS is nearly three times of GPRS, is nearly ten times of GSM.
This following characteristic of crossing energy consumption mainly due to UMTS:
The operation that the realization of ■ UMTS base band more consumes CPU (" CPU ", or " central location ") than GSM base band.
■ is because QPSK (" quaternary PSK ") modulation, and radio needs a very linear emission power amplifier, therefore efficient very low (about 10%, rather than 50%) on GSM.
Transmitting and receiving under the ■ dedicated mode continues to carry out, and GSM runs on " pulse " (being rafales) pattern;
■ UMTS frame is than GSM frame longer (10ms rather than 4.615ms).
One places the duration of the radio communication equipment of UMTS cellular cell therefore to be significantly less than the duration that runs on the same equipment on the GSM.
Yet, some application, for example voice call and low speed transmissions, quality online and that can obtain equating on the net at UMTS at GSM/GPRS.Thereby when the user wished to insert these application, his radio communication equipment need not insert GSM net (more power consumption).
Yet, still allow that without any technology controlling this equipment when radio communication equipment can insert the network of a plurality of different energy consumption characteristics inserts this or that network so far.
Summary of the invention
Purpose of the present invention is exactly these disadvantages of slowing down former method.
Or rather, the purpose of this invention is to provide a kind of technology that is controlled at the business of utilizing on the radio communication equipment, to optimize the battery energy management of this equipment.
Especially, the purpose of this invention is to provide a kind of like this technology, this technology is allowed the complete execution that guarantees once-through operation to the user.
A further object of the invention: a kind of like this control technology is provided, and this technology guarantees higher in terms of existing technologies service quality to the user.
Another object of the present invention is to implement this reliable technique, even when cell degradation.
A further object of the invention: a kind of so simple and not high technology of implementation cost is provided.
These purposes as other purpose that will occur subsequently, all are to reach by a kind of at least one professional method of implementing on the radio communication equipment that is controlled at, and this method is allowed at least two different business of assurance.
According to the present invention, if the energy of the consumption of described equipment between the described service period of enforcement meets the criterion of the described device battery energy of optimum management, this method just comprises that is authorized a step of implementing one of described business.
Therefore, the present invention is based on a kind of novelty and the method for the business implemented on the creative control radio communication equipment.In fact, the present invention proposes: before starting any application or business, consider the criterion of optimum management remaining battery duration,, or be enough to starting another one to user's operations necessary afterwards so that can guarantee that dump energy will be enough to complete operation to the user.
The present invention thereby become in terms of existing technologies an important innovation; Prior art can not be determined the dump energy in the battery reliably, more can not provide a kind of to the user and control the means of each application that can insert of startup or business.
The present invention thereby provide a kind of convenient service to the user, the use of managing better his mobile phone or PDA is allowed in this service.
Advantageously, this method also comprises a preliminary step of determining dump energy in the described radio communication equipment battery, and, having only when described dump energy is higher than a predetermined threshold value, we just authorize one of described each business of implementing.
According to first favourable feature of the present invention, described business comprises at least one voice communications applications and at least one additional application.
Therefore, the present invention for example is applied to simple telephone talk, but also is applied to remote loading file or video, is applied to multimedia application, or the like.
According to another favourable feature of the present invention, described business is the access service of described equipment at least two different radio communication nets.
We certainly consider common implementing the present invention for the business of the business of application type and access service type.
Advantageously, described radio communication net belongs to a set that comprises as the lower part:
■ GSM net;
■ UMTS net;
■ GPRS (English " GSM Packet Radio Service ", i.e. " GSM packet wireless business ") net;
■ EDGE (English " Enhanced Data for GSM Evolution ", i.e. " GSM that strengthens data transfer rate evolves ") net;
■ IS95 net;
■ CDMA2000 net;
■ PDC net.
For example, the present invention thereby allow mobile phone is switched to GSM/GPRS net (low energy consumption) from UMTS net (high energy consumption) is to optimize the management of dump energy in its battery.
In fact, for example, when described equipment uses the access service of radio communication net of minimum power consumption, optimize criterion and just be verified.
Best is, described threshold value is calculated as can allow that described application intactly carries out an operation.
Therefore, have only as user when certainly he can finish the operation that he wishes to carry out, he just can start an application, and this has been avoided losing time in rain and the energy content of battery.
Best is, is under the situation of a file of remote loading in described operation, and described threshold value is considered the size of described file.
In fact, we determine the time that remote loading is required according to the size of file, thereby determine that respective application is once that complete remote loading is with the energy that consumes.Have only when we consider to remain the duration and certainly intactly during remote loading, we just authorize remote loading.
Best is, described threshold value has been considered a nargin, and some energy of allow retention, these energy are enough to guarantee at least once voice call in selected time limit.
Therefore, the user has kept the possibility of making a call last, for example in case of emergency.
Advantageously, this method comprises the step of a prompting, indicates the dump energy of estimation after described service implementation is finished and/or the residue air time of estimation.
Therefore, for example, must make a call one long the time, use the remaining air time of back and seem that inadequately he just can select not carry out this application if execute another one when the user reckons with.
Best is, has only when the residue air time of the dump energy of estimation or estimation is lower than predetermined threshold value, and described prompting step is just carried out.
This threshold value can be set by equipment or by the network that links to each other with equipment in advance, and is perhaps selected by the user.
According to a favourable feature of the present invention, at least two of the step of described definite dump energy considerations can be by the required concrete energy of different business of described equipment access; Adjust according to the business that is used and/or planned to use described service time.
The present invention thereby proposition not only will be considered the battery remaining power of a certain given time, also to consider the energy that different application consumed of equipment, thereby can indicate him to the user and whether can also use in the application that he can insert each, and how long can use.
Best is that we are according to the charge level of described battery, and a concrete professional energy needed is carried out in consideration respectively, calculate at least two and remain service time.
Advantageously, the step of described definite dump energy is considered the characteristic that at least one represents described battery.
Best is that the step of described definite dump energy is implemented the measurement to the terminal 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 slopes different straightway 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 (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:
-be stored in the described dump energy at least one predetermined point of in the nonvolatile memory, described discharge curve;
The start-up time of at least one parts of-described radio communication equipment;
The theory consumption of described at least one parts of-described equipment.
Therefore, in that those are not known on the point of its energy in advance on the discharge curve, we by assessment since discharge curve be stored go up a bit since energy consumption come the dump energy of counting cell at this point.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, 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.
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.
According to the first favourable modification of the present invention, described authorisation step is implemented by described radio communication equipment.
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 network challenge equipment---for example according to a regular time at interval---is to learn the residue duration of battery.
According to the second favourable modification of the present invention, described mandate is carried out the step of one of described application by described network implementation.

Embodiment
The overall principle of the present invention is based on the Charge Management of optimizing by the business of control appliance application the radio communication equipment battery.Under a special execution mode, the present invention is based on the dump energy of determining the radio communication equipment battery, carry out a specific application so that when dump energy is not enough, can control---forbidding in case of necessity---.
We tell about the example of using radio communication equipment 1 of the present invention and associated batteries 2 corresponding to Fig. 1.
The equipment of drawing among 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.
In other words, according to the present invention, every the business that we can insert according to the user or the intrinsic energy consumption of application are determined their residue service time separately.
1. determine battery remaining power
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, the voltage at its terminal place 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 is with regard to according to upgrading the monitoring of battery continuous 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.We also consider the operational mode (for example GSM or UMTS) of mobile phone, use intrinsic energy consumption so that therefrom extrapolate each.
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.
2.
Upload information to network about the remaining battery duration
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 with the form of a standardized messages 6, 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 the head of a legacy protocol and one " body ", i.e. body, this body has comprised the information with the remaining battery time correlation.
Can consider that two kinds are implemented modification.
2.1.
Network calculations remains service time
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 each application that the user can insert, is determined 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 communication 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.
2.2.
Mobile device calculates and remains service time
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 function of voice communication, 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 (perhaps, even the residue of being apprised of each application the user after service time by user oneself) fully.Contrast Fig. 4, this execution mode is described in more detail.
3.
Carry out the mandate of using during the mobile phone management
On Fig. 4, radio communication equipment 1 is a mobile phone, and it allows that the user inserts following application:
■ sends the application of note 40;
The application of ■ remote loading file 41, for example remote loading from the Internet;
■ Video Applications 42, it for example can allow the user see a film;
■ voice communications applications 43.
When the user wishes to carry out when using 40 among 43 one, mobile phone 1 is at first determined dump energy in (44) battery 2 according to said method.
Known be labeled as 40 to 43 each use in after each the per second energy consumption, the microprocessor of phone 1 is just therefrom extrapolated the residue service time of each application by division arithmetic.
For example, we obtain following residue service time:
■ 15 minutes: send note 40;
■ 1 minute and 30 seconds: remote loading file 41;
■ 3 minutes: Video Applications 42;
■ 11 minutes: voice communications applications 43;
If the user represents to wish to send a note, the time of this operation is lower than 15 minutes, and phone 1 is just authorized and carried out application corresponding 40, and is as shown in arrow 45.
If the user wishes to set up a voice communication, phone 1 just can show a piece of news on screen, shows the duration that he has was enough to make a call 11 minutes to the user.Also parameter setting can be the telephone relation of only authorizing below 10 minutes, as shown in arrow 46, so that be that last urgent brief a calling keeps enough duration.
If the user starts Video Applications 42, for example in order to watch a fragment of 8 minutes, phone 1 just detects this time and is longer than the residue service time of estimating into Video Applications 42, thereby forbids that (48) user carries out this application.
At last, if the user wishes 41 1 files of remote loading, mobile phone 1 will at first be determined the size of file that will remote loading.So microprocessor is therefrom extrapolated the required time of this operation according to remote loading speed.If this time is longer than 1 minute 30 seconds the residue service time of estimating previously (for example allowing the file of a maximum 500Ko of remote loading), mobile phone 1 is not just authorized and is carried out remote loading and use 41, as being labeled as indicated in 47 the arrow.
If the user selects to start the application 40 that sends note, mobile phone 1 can also show a piece of news on screen, be used to inform that---for example after having sent two notes---user: owing to use 40 energy that consume, he has only had 5 minutes maximum voice communication time again.
Thereby because control method of the present invention, the user can have benefited from the more intellectualized management to the dump energy of radio communication equipment battery.
4.
Mobile phone is inserted the management of the mandate of dissimilar radio communication nets
Except management inserted the application of some voice call type or file remote loading type, the present invention can also be used to manage the type of the radio communication net that the multi-mode radio mobile device inserts.In other words, the present invention allows the selection of the RAT (English " Radio Access Technology ", i.e. " wireless access technology ") of managing radio communication equipment.
Pointed as this paper front contrast Fig. 5, when mobile phone runs on the UMTS pattern, rather than for example when GSM or GPRS pattern, the more much more energy of its consumption.
For example, the present invention allows that assurance GSM/UMTS dual-mode mobile phone places the UMTS cellular cell as far as possible infrequently, to keep its duration to greatest extent.
4.1.
Radio communication equipment is selected RAT
Select RAT to operate by wireless device.For example, when according to aforementioned mechanism, when mobile phone detected battery faint electric weight is only arranged again, it just stopped the measurement activity of any UMTS type, and only authorizes the conversation of GSM type again.
When battery remaining power was lower than a predetermined threshold value (set in advance, or disposed by the user), the automatic switchover from the UMTS pattern to the GSM/GPRS pattern had just taken place.
Otherwise if the user charges again to battery, it is double mode that mobile phone can initiatively switch back " entirely " GSM/UMTS again, to authorize the application that starts very at a high speed.
This automatic switchover is to being possible by one of four class dual-mode mobile phones of the TR21.910 standard defined of 3GPP (English " Third Generation PartnershipProject ", i.e. " third generation partnership projects ").Under this background, there is one first switched system, promptly manual " switching " system and three automatic " switching " systems.When from the UMTS mode switch to the GSM/GPRS pattern, mobile phone switches to manual " switching " system from one of three automatic " switching " systems.Yet we will notice that this manually " switching " system does not allow the user of mobile phone get involved, but be implemented to switch by mobile phone oneself.
We also will notice under the GSM/GPRS pattern, and mobile phone is as GSM monotype equipment operation: double mode mechanism thus is stopped.Especially, the cellular cell search and the synchronizing function (" cellular cell search " and " multipath search ") of the UMTS of phone part are inoperative.Mobile phone thereby also no longer upload the measurement data of UMTS cellular cell, this has facilitated the lot of energy saving.
4.2.
Network selecting RAT
According to this second enforcement modification, select RAT by network, so that guiding is selected cellular cell for mobile phone, especially in the operation of " handover " (switching).
Except the result of the power and communication quality uploaded by mobile phone, and beyond the criterion of cellular cell overload, according to the present invention, network keeps the data about the remaining battery duration of being come by mobile phone transmission, to select RAT.
As previously mentioned, network receives the message of mobile phone, and this message shows the remaining battery duration (with the form of dump energy and/or residue service time) to network.
For example, if should the duration deficiency, network switches to independent GSM/GPRS pattern with mobile phone.For this reason, it can also keep following criterion:
The application that ■ user wishes to implement (voice or low speed data transmission, these needn't move on UMTS);
The quality of reception of ■ mobile phone;
The saturation of ■ GSM or UMTS cellular cell.
When battery is charged again, or when the user asks to carry out high-speed applications, for example during video " stream " type, network can switch to the UMTS pattern again with radio communication equipment.
The type of the present invention thereby the radio communication net that inserts by control appliance not only, and the type of the application that the control user implements under a given operational mode (for example UMTS or GSM), allow the use of the managing radio communication equipment energy content of battery better.
These two kinds of execution modes can be implemented independently of each other, perhaps merge to get up simultaneously and implement.We it is also contemplated that the control of carry out using is managed by radio communication equipment, and, we simultaneously, manage RAT by network and select.The present invention also is applied to any other combination of these two kinds of execution modes: for example, RAT selects to be implemented by radio communication equipment, and can be implemented by radio communication net the control of using.
