Definitions
- the present invention relates to a method for power regulation for a mobile communication terminal, a suitable circuit and a mobile communication terminal with such a circuit.
- Mobile communication terminals especially cell phones based on the GSM standard, must
- U_nenn when fully charged.
- a certain transmission power or performance must be guaranteed. For example, a signal with a transmission power that reaches a certain value P_reduc_spec must be able to be sent.
- the standard stipulates that, when operating below this defined voltage value, for example below 0.85 or 0.9 * U_nom, it must be ensured that no adjacent channels are disturbed.
- a major disadvantage of the known procedure is that a battery is not optimally used in terms of its capacity. Rather, the mobile communication terminal is switched off long before the battery is used up. In the case of a cell phone, the speaking time is also severely limited.
- a method for power regulation for a mobile communication terminal which comprises a battery with a time-dependent battery voltage and a power amplifier, in which the battery voltage is determined before transmission of a signal from a control and monitoring unit and with a predetermined upper threshold voltage U_nenn * is compared the signal is sent with a predetermined transmission power producing a voltage drop ⁇ Ul correlating with the predetermined transmission power if the battery voltage is above the upper threshold voltage U_nenn * , the signal with a reduced transmission power determined by the control unit, producing one with the reduced transmit power correlating voltage drop ⁇ U2 is sent if the battery voltage is less than or equal to the upper threshold voltage U_nom * , the reduced transmit power being selected such that the battery voltage minus the voltage dip ⁇ U2 correlating with the reduced transmit power is greater than or equal to a predetermined value lower threshold voltage U_Burst is.
- the voltage of the battery decreases with a decreasing battery capacity.
- the transmit power reduced to P_reduc_spec which is accompanied by a reduction in the voltage drop to a voltage drop ⁇ U2.
- This voltage drop ⁇ U2 then remains constant. If the battery voltage minus the voltage drop ⁇ U2 then falls below a predetermined switch-off voltage U_about, the mobile communication terminal is switched off.
- the mobile communication terminal with reduced transmission power can now be kept in operation until the battery is almost completely discharged, since below the defined voltage value U_nom * there is no constant voltage drop ⁇ U2, ie no constant transmission power becomes.
- U_nom * there is no constant voltage drop ⁇ U2
- U_Burst a predetermined lower threshold voltage
- the mobile communication terminal is switched off when the voltage drop ⁇ U2 is equal to or less than a predetermined threshold voltage drop.
- the transmission power that correlates with a specific voltage drop is particularly preferred in this case until a predetermined one, for example from a base Required minimum transmission power is reached. Only then is the mobile communication terminal switched off.
- the transmission power as a function of the battery voltage is reduced such that the battery voltage minus the voltage dip ⁇ U2 correlating with the transmission power is equal to the lower predetermined threshold voltage U_Burst.
- the reduction of the transmission power over the discharge time of the battery is continuous.
- the method according to the invention has considerable advantages. This means that an existing battery capacity can be used much better. Furthermore, the talk time increases considerably in the case of a mobile phone. At the same time, the technical parameters described in the specification TS45005 are also maintained under extreme conditions by the method according to the invention. The reduction of the transmission power provided according to the invention below a defined voltage value U_nenn * of the battery voltage is in accordance with the specification.
- the present invention comprises a circuit for power regulation for a mobile communication terminal.
- the circuit according to the invention comprises at least the following elements: a rechargeable battery with a time-dependent rechargeable battery voltage, a receiving and transmitting unit for the cordless reception and transmission of signals, a power amplifier for setting a transmission power of a signal to be transmitted, a baseband controller, a control and monitoring unit, the control and monitoring unit with the battery for querying the battery voltage, with the receiving and transmitting unit for querying a required minimum transmission power and with the power amplifier for setting the of the
- Control unit is connected to determinable transmission power.
- control and monitoring unit is integrated in the baseband controller. It is also conceivable to integrate the control and monitoring unit in the power amplifier or the receiving and transmitting unit. Integration advantageously takes place in a so-called baseband controller, since all the information for calculating a control or regulating variable of the power amplifier is present in a baseband controller.
- the present invention also relates to a mobile communication terminal, a circuit according to the invention being integrated therein.
- FIG. 1 Comparison of the course of a battery voltage of a battery of a mobile communication terminal as a function of time according to an operational management according to the prior art (Fig. La) with the course of a battery voltage of a battery of a mobile communication terminal as a function of time according to an embodiment of the inventive method (Fig. Lb);
- Fig. 2 Schematic representation of an embodiment of a circuit according to the invention
- Figure la shows a curve of a battery voltage as a function of time, as it looks when operating a mobile communication terminal according to the prior art.
- U_nom the battery voltage decreases over time, even if no signals are sent, as in the course of section 1, for example.
- a voltage drop ⁇ Ul occurs, as explained at the beginning.
- This voltage drop ⁇ Ul is coupled to a specific transmission power P.
- the transmission power P is reduced to P_reduc_spec, which goes hand in hand with a reduced voltage drop ⁇ U2.
- the voltage drop ⁇ U2 remains constant. If the operating voltage falls below during transmission, i.e. the battery voltage minus the voltage dip ⁇ U2 a predetermined switch-off voltage U_Abschalt, the mobile communication terminal switches off.
- the mobile communication terminal in FIG. 1b switches off much later using an embodiment of the method according to the invention at the same transmission frequency.
- the voltage dips ⁇ U2 that occur when signals are sent are not only reduced once to a certain value and then kept constant in all subsequent transmission actions, but the reduced transmission power is selected so that the battery voltage is reduced of the with the reduced transmission power Relative voltage drop ⁇ U2 is greater than or equal to a predetermined lower threshold voltage U_Burst, ie the voltage drop ⁇ U2 correlating with the reduced transmission power is successively reduced. This process is ongoing.
- the voltage drop ⁇ U2 correlating with the reduced transmission power is reduced to a certain predetermined threshold voltage drop value, which is specified indirectly, for example, by a base station when it requires a minimum transmission power.
- the lower threshold voltage U_Burst is specified by all circuit elements to be supplied in the mobile communication terminal.
- the mobile communication device preferably only switches off when the voltage drop ⁇ U2 falls below a predetermined threshold voltage drop.
- This drop in threshold voltage, which is coupled with a specific threshold transmission power can be specified, for example, by a base station, which requires a predefined threshold transmission power in the sense of a minimum transmission power.
- a mobile communication terminal with a power control according to one embodiment of the method according to the invention can transmit significantly longer.
- the capacity of the battery is better used.
- FIG. 2 shows a schematic representation of an embodiment of a circuit according to the invention.
- a rechargeable battery 1 is shown.
- the rechargeable battery 1 is connected to a control and monitoring unit 2 via a connection a.
- This control and monitoring unit 2 is in turn connected via a connection b connected to a transmitting and receiving unit 3 and via a connection c to a power amplifier 4.
- Via the Connection a of the control and control unit 2 to the battery 1 gives the control and control unit 2 information about the currently available battery voltage.
- the control and monitoring unit 2 receives information about a minimum or threshold transmission power required, for example, by a base station.
- control and monitoring unit 2 it is now determined according to the invention which transmission power, combined with a voltage drop correlating therewith, is to be realized on the power amplifier 4.
- This information or control instruction is forwarded via connection c to the power amplifier 4, which realizes the corresponding transmission power in accordance with this control instruction.
- a baseband controller is also provided, in which the control and monitoring unit 2 is preferably integrated.
- receiving amplifier 5 a so-called low noise amplifier, for incoming signals.
