Abstract

For monitoring a battery status of a battery included in a mobile communication device (1), battery status reports are received (S12) in a computerized service unit (2) via a mobile radio network from the mobile communication device (1). The battery status reports include at least an electrical battery parameter indicative of a current charge or voltage level of the battery. Based on the battery status reports, received from the mobile communication device (1), battery data is stored (S17) in the computerized service unit (2), the battery data including at least a time series of the electrical battery parameter. Using the battery data, determined is a deviation of a battery parameter, included in the battery status report, from an expected value of the battery parameter derived from the battery data.

Claims

1. A method of monitoring a battery status of a battery included in a mobile communication device, the method comprising:

receiving in a computerized service unit via mobile radio network battery status reports from the mobile communication device, the battery status reports including at least an electrical battery parameter indicative of a current charge or voltage level of the battery; and

storing in the computerized service unit battery data, based on the battery status reports received from the mobile communication device, the battery data including at least a time series of the electrical battery parameter.

2. The method of claim 1, further comprising receiving in the computerized service unit battery related event information included in the battery status reports from the mobile communication device, the battery related event information including at least one of:

time when the battery was installed, time when battery recharging started, time when battery recharging completed, time when standby mode was turned on, and time when standby mode was turned off; and

storing in the computerized service unit battery data including the battery related event information.

3. The method of claim 1, further comprising receiving in the computerized service unit ambient temperature information associated with the battery and included in the battery status reports from the mobile communication device;

and storing in the computerized service unit battery data including the ambient temperature information associated with the battery.

4. The method of claim 1, further comprising determining in the computerized service unit, using the battery data, an expected value of a battery parameter;

determining a deviation of a battery parameter, included in the battery status report, from the expected value of the battery parameter; and

transmitting a battery alarm signal from the computerized service unit to one or more recipients, assigned in the computerized service unit to the mobile communication device, for cases where the deviation exceeds a defined deviation threshold.

5. The method of claim 1, further comprising determining in the computerized service unit, using the battery data, an average recharging cycle time at the mobile communication device;

and generating in the computerized service unit a battery alarm signal for cases where the average recharging cycle time deviates from an expected value of the recharging cycle time.

6. The method of claim 1, further comprising determining in the computerized service unit, using the battery data, a threshold level for triggering in the mobile communication device a low battery warning signal;

and transmitting the threshold level from the computerized service unit to the mobile communication device.

7. The method of claim 1, further comprising receiving in the computerized service unit a low battery warning signal from the mobile communication device;

and generating in the computerized service unit a battery recharging alarm for cases where the battery is not recharged or replaced at the mobile communication device within a defined time limit after the low battery warning signal.

8. A computerized service unit comprising:

a communication module configured to receive via a mobile radio network periodic battery status reports from a mobile communication device, the battery status reports including at least an electrical battery parameter indicative of a current charge or voltage level of the battery; and

a battery analyzer configured to store in the computerized service unit battery data, based on the battery status reports received from the mobile communication device, the battery data including at least a time series of the electrical battery parameter.

9. The computerized service unit of claim 8, wherein the battery analyzer is further configured to store in the computerized service unit battery data including battery related event information received in the battery status reports from the mobile communication device, the battery related event information including at least one of:

time when the battery was installed, time when battery recharging started, time when battery recharging completed, time when standby mode was turned on, and time when standby mode was turned off.

10. The computerized service unit of claim 8, wherein the battery analyzer is further configured to store in the computerized service unit battery data including ambient temperature information associated with the battery and received in the battery status reports from the mobile communication device.

11. The computerized service unit of claim 8, wherein the battery analyzer is further configured to determine, using the battery data, an expected value of a battery parameter, to determine a deviation of a battery parameter, included in the battery status report, from the expected value of the battery parameter, and to transmit a battery alarm signal to one or more recipients, assigned in the computerized service unit to the mobile communication device, for cases where the deviation exceeds a defined deviation threshold.

12. The computerized service unit of claim 8, wherein the battery analyzer is further configured to determine, using the battery data, an average recharging cycle time at the mobile communication device, and to generate a battery alarm signal for cases where the average recharging cycle time deviates from an expected value of the recharging cycle time.

13. The computerized service unit of claim 8, wherein the battery analyzer is further configured to determine, using the battery data, a threshold level for triggering in the mobile communication device a low battery warning signal, and to transmit the threshold level to the mobile communication device.

14. The computerized service unit of claim 8, wherein the battery analyzer is further configured to generate a battery recharging alarm for cases where the battery is not recharged or replaced at the mobile communication device within a defined time limit after a low battery warning signal has been received in the computerized service from the mobile communication device.

15. A battery powered mobile communication device comprising a battery monitoring system configured to monitor a battery status of the battery, the battery status including at least an electrical battery parameter indicative of a current charge or voltage level of the battery,

wherein the battery monitoring system is further configured to generate and transmit battery status reports via a mobile radio network to a computerized central service unit, the battery status reports including at least the electrical battery parameter, for generating and storing at the computerized central service unit battery data including at least a time series of the electrical battery parameter.

16. The mobile communication device of claim 15, wherein the battery monitoring system is further configured to transmit to the computerized service unit battery related event information included in the battery status reports, the battery related event information including at least one of:

time when the battery was installed, time when battery recharging started, time when battery recharging completed, time when standby mode was turned on, and time when standby mode was turned off, for storing in the computerized service unit battery data including the battery related event information.

17. The mobile communication device of claim 15, wherein the battery monitoring system is further configured to measure and transmit to the computerized service unit ambient temperature information associated with the battery and included in the battery status reports, for storing in the computerized service unit battery data including the ambient temperature information associated with the battery.
