Embodiment Construction

[0047] figure 1 is the battery voltage V displayed as a measure of the battery's charge level batt how time t use changing graph. Power consumption varies largely depending on a number of different factors. If the terminal is only maintained in a waiting state, the so-called "standby" state, a fully charged battery will last a long time before it is exhausted. If the terminal is used for transmitting and receiving very frequently, the battery will naturally be used up much faster. If the signal reception conditions are poor at the place where transmission and reception are performed, the power consumption will be greatly increased compared to the usual environment. Therefore, the time scale and length of the curve will vary largely with its primary end use.

[0048] The form of the curve also depends on the type of battery used. Many battery types have a flat and slowly decreasing characteristic battery curve. When the charge starts to run out after some usage time, the...

Abstract

The present invention relates to mobile radio communication. More particularly, the invention relates to a method, a device and a terminal (10) for mobile radio communication, which comprises an antenna unit (102), a radio portion (104), a control unit (120), a unit (122) for storing of control programs, a unit (124) for storing of data, a keypad unit (110), a display unit (112), a power supply unit (12) which is the sole common storing unit for electrical charge, a means (26) for sensing the electrical charge in the power supply unit (12) and for determining a matched measuring signal (CL) which corresponds to the electrical charge of the power supply unit, a comparison means (32) for continuous determination of the difference between the matched measuring signal (CL) and a reference signal (Uref), which is a conversion of a reference value parameter R. The invented device comprises a means (50) for selecting and assigning to the reference value parameter R a value (R(1); RH) if reserve power is to be reserved and a value (R(0); RL) if the reserve power is to be used. The change of reference values can be blocked by an unlockable blocking means.

Description

technical field [0001] The present invention relates to the technical field of mobile radio terminals, more precisely, the invention relates to terminals for mobile radio communications, and methods and arrangements for conserving reserve power for terminals of this type. The present invention also provides a method and device for blocking the use of standby power, a method for unlocking, and a terminal with these functions. Background technique [0002] A wireless terminal can be divided into a number of main functional units. The power transfer unit supplies electric power to other units of the terminal. In small handheld wireless terminals used for telecommunications, the power transfer unit is a rechargeable energy storage, colloquially known as a battery. Most often, a depleted battery can be replaced with a fully charged one. Replacement can be done with at most a few simple operations. However, there are also terminals where it is possible to charge the battery wh...
