1. A method for calculating a consumed charge Q referred to a period Δ
- t in a mobile device with mains-independent power supply, which can be in different system states in the period Δ
t, comprising;
determining a period of a receiving/transmitting state in which the mobile device is in a transmitting state or in a receiving state in the period Δ
t;
reading out a stored current value for a current typical of the receiving/transmitting state from a memory; and
multiplying the stored current value with the period determined in order to calculate the consumed charge Q for the receiving/transmitting state occurring in the period Δ
t.

Abstract
A method for calculating the power consumption of a mobile device, particularly of a mobile station of a mobile radio system, in an observation period Δt based on various possible system states sk in which the device can be in the period Δt. A value of a quantity Δk is determined system-state-dependently for the system states sk occurring in the period Δt. The power consumption in the period Δt is calculated in such a manner that the quantities Δk and state-dependent typical currents ik are taken into consideration.

14. A method for calculating a consumed charge Q referred to a period Δ
- t in a mobile device with mains-independent power supply, which can be in different system states in the period Δ
t, in which the system states exhibit a receiving/transmitting state in which the mobile device operates in a receiving state and in a transmitting state in the period Δ
t, and a frequency-changing state in which the carrier frequency is changed in the period Δ
t, the method comprising;
determining a first period in which the mobile device is in the transmitting state in the period Δ
t;
determining a second period in which the mobile device is in the receiving state in the period Δ
t;
determining a third period in which the mobile device is in the frequency-changing state in the period Δ
t;
reading out a stored first current value for a current typical of the transmitting state from a memory;
reading out a stored second current value for a current typical of the receiving state from a memory;
reading out a stored third current value for a current typical of the frequency-changing state from a memory; and
multiplying the first, second and third current values by the first, second and third periods to calculate the consumed charge Q for the transmitting, receiving and frequency-changing state occurring in the period Δ
t.
