Abstract
The invention relates to a method for controlling power for a mobile communications terminal, which comprises a battery with a time-dependent battery voltage and comprises a power amplifier. The invention provides that before the transmission of a signal, the battery voltage is determined by a control and testing unit and is compared to a predetermined upper threshold voltage U nominal*. The signal is transmitted with a predetermined transmit power while creating a voltage dip Delta U1, which is correlated with the predetermined transmit power, when the battery voltage is greater than the upper threshold voltage U nominal*. The signal is transmitted with a reduced transmit power while creating a voltage dip Delta U2, which is correlated with the reduced transmit power, when the battery voltage is less than or equal to the upper threshold voltage U nominal*. The reduced transmit power is selected in such a manner that the battery voltage minus the voltage dip Delta U2, which is correlated with the reduced transmit power, is greater than or equal to a predetermined lower threshold voltage U burst.

Technical field
The present invention relates to a kind ofly regulate method, the suitable circuit of power and have the mobile communication transmitting apparatus of this circuit for the mobile communication transmitting apparatus.
Background technology
The mobile communication transmitting apparatus, especially must satisfy the requirement of GSM standard TS45005 according to the mobile phone of GSM standard.The mobile communication transmitting apparatus drives with rechargeable battery usually.With 2.2 volts of drivings of Annex D, its characteristic is met in this rechargeable battery types in this regulation.Rechargeable battery has maximum cell voltage U_nenn under the state that is full of electricity.In afore mentioned rules, except that other, also be limited to cell voltage and drop to before the stop voltage value, as U_nenn
*=0.85 or 0.9 * U_nenn, must guarantee specific transmitted power performance in other words.Like this, for example must send signal with the transmitted power that reaches particular value P_reduc_spec.
In addition, this standard also stipulates, must guarantee under the magnitude of voltage that is limited, just for example 0.85 or 0.9 * U_nenn under when moving, can not disturb adjacent channel.
Up to now, in mobile phone and gsm module, come very strictly to explain this regulation like this, under the magnitude of voltage that limits, just at U_nenn
*=0.85 or 0.9 * U_nenn under transmitted power can reach the P_reduc_spec value at least.If this transmitted power can not reach, then close the mobile communication transmitting apparatus automatically.But the latter is again unwanted with regard to regulation TS45005.
A very big shortcoming of known method is that rechargeable battery is not used by the best with regard to its capacity.But the mobile communication transmitting apparatus just had been closed before rechargeable battery exhausts.Thus, under the situation of mobile phone also strong restrictions the air time.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of possibility, can utilize the capacity of the rechargeable battery of mobile communication transmitting apparatus better.
Technical problem of the present invention solves by the inventive method of claim 1, the circuit of claim 5 and the mobile communication transmitting apparatus of claim 7.Other preferred implementation provides in the corresponding dependent claims.
Provide a kind of method for mobile communication transmitting apparatus adjusting power according to claim 1, this communication transmitting apparatus comprises the rechargeable battery and the power amplifier of the cell voltage with the time of depending on, wherein,

*Compare,
If-cell voltage is greater than upper threshold voltage U_nenn
*, then under the condition that produces a voltage disturbance Δ U1 that predetermined transmitted power is proofreaied and correct with this, send this signal with predetermined transmitted power,
If-cell voltage is less than or equal to this upper threshold voltage U_nenn
*Then use the transmitted power of determining by control unit that reduces under the condition of the voltage disturbance Δ U2 that produces the transmitted power correction that reduces with this, to send this signal, wherein select this transmitted power that reduces like this, make cell voltage after having deducted the voltage disturbance Δ U2 that proofreaies and correct with the transmitted power that reduces more than or equal to the threshold voltages U_Burst that is scheduled to.
Generally known, along with the voltage that reduces rechargeable battery of rechargeable battery capacity also reduces.Power amplifier in the mobile communication transmitting apparatus is within the equipment of maximum customer.When sending signal, produce electric current, on the internal resistance of rechargeable battery, have voltage disturbance thus all the time.The variation of the time of electric current is an impulse form when sending burst, also can occur the voltage disturbance of impulse form thus.These voltage disturbances are determined the close moment of mobile communication transmitting apparatus at last.Proofread and correct this voltage disturbance with corresponding transmitted power.According to described regulation TS45005, voltage disturbance Δ U1 in the specific voltage value that drops to cell voltage (as U_nenn
*=0.85 or 0.9 * U_nenn) all must keep constant before.Magnitude of voltage U_nenn in this qualification
*Under, the power by limiting power amplifier is reduced to P_reduc_spec with transmitted power at present, and this makes this voltage disturbance be reduced to voltage disturbance Δ U2.Voltage disturbance Δ U2 keeps constant then.If cell voltage less than the predetermined voltage U _ Abschalt that closes, is then closed the mobile communication transmitting apparatus after deduction voltage disturbance Δ U2.The method according to this invention is, up to the magnitude of voltage that limits (as U_nenn
*All provide described regulation desired maximum transmit power till=0.85 or 0.9 * U_nenn).But under the magnitude of voltage of this qualification, opposite with current measure, all use littler transmitted power that the mobile communication transmitting apparatus is remained on running status till up near the discharging fully of rechargeable battery the time, because the magnitude of voltage U_nenn that is limiting
*Under, constant voltage disturbance Δ U2 is not provided, constant transmitted power just is not provided.But according to the present invention, guarantee cell voltage after the voltage disturbance Δ U2 that deduction is proofreaied and correct with the transmitted power that reduces more than or equal to the threshold voltages U_Burst that is scheduled to.Guaranteed that thus all circuit elements that should power are all enough powered, and therefore kept the function good state.At this, important circuit element is voltage regulator and power amplifier.
In the preferred implementation of the inventive method,, then close the mobile communication transmitting apparatus if voltage disturbance Δ U2 is equal to or less than predetermined voltage disturbance threshold value.
Particularly preferably be, the transmitted power of proofreading and correct with the specific voltage disturbance is reduced to till minimum transmit power predetermined, that for example required by the base station reaches always.At this time of day just close the mobile communication transmitting apparatus.
Preferably, if cell voltage is less than or equal to upper threshold voltage U_nenn
*, then reduce transmitted power according to this cell voltage, make this cell voltage after the voltage disturbance Δ U2 that deduction is proofreaied and correct with transmitted power, equal predetermined threshold voltages U_Burst.Reducing on the charging interval of rechargeable battery of transmitted power is continuous.
Method of the present invention has provided lot of advantages.Like this, can utilize existing rechargeable battery capacity better.In addition, under the situation of mobile phone, significantly improved the air time.Also keeping the technical parameter of in regulation TS45005, describing under the maximum conditions by method of the present invention simultaneously.According to of the present invention, at the stop voltage value U_nenn of rechargeable battery voltage
*Under reduce transmitted power and meet this regulation.
In addition, the present invention also is included as the circuit that the mobile communication transmitting apparatus is regulated power.Circuit of the present invention comprises following element at least:
-have a rechargeable battery of the cell voltage of the time of depending on,
