Method and arrangement for controlling the operation of mobile communication equipment in a power-off state
First Claim
1. A method for controlling the operation of mobile communication equipment in a power-off state, in which part of the mobile communication equipment is kept in operation for receiving and analyzing at least one excitation signal (VBAT, VCHAR, PWR_BTN, ALARM), wherein, said method comprises steps of:
- keeping only a first part (30) of the mobile communication equipment, which essentially consists of timing means, in continuous operation, and controlling a second part (29, 31, 32, 18), provided for receiving and analyzing said signals of the mobile communication equipment, by means of said first part (30) to operate and analyze said signals during specified time intervals (t1), and to be inoperative at another time (t2), wherein radio frequency (RF) components of the second are powered-off during the power-off state; and
wherein said analyzing of said signals is accomplished during said power-off state.

Abstract
Control of the operation of mobile communication equipment is provided in a power-off state, wherein a part of the mobile communication equipment is kept in operation for receiving and analyzing at least one of a set of excitation signals (VBAT, VCHAR, PWR_BTN, ALARM). Only a first part (30) of the mobile communication equipment, which essentially consists of timing means, is kept in operation continuously. A second part (29, 31, 32, 18) of the mobile communication equipment, provided for receiving and analyzing the signals, is controlled by means of the first part (30) to operate and analyze the signals during specified time intervals (t1), and to be inoperative at another time (t2). Power for a radio frequency (RF) transmitter and receiver of the second part is switched off during the power-off state. Analysis of the signals is accomplished during the power-off state.
