Methods and apparatus for limiting communication capabilities in mobile communication devices
A computer-readable medium having computer-readable instructions stored on the computer-readable medium for execution of the computer-readable instructions by a processor to use in a mobile device having a visual display is provided. The instructions comprise monitoring an operating temperature at the device and, when the monitored operating temperature is greater than a first threshold temperature, allowing only emergency communication and providing a visual indication indicating that only emergency communication is allowed.
1. A non-transitory computer-readable medium having computer-readable instructions stored on the non-transitory computer-readable medium for execution of the computer-readable instructions by a processor to use in a mobile device having a visual display, said computer-readable instructions comprising:
monitoring an operating temperature at the device;
when the monitored operating temperature is greater than a first threshold temperature:
allowing only emergency communication; and
providing a visual indication indicating that only emergency communication is allowed.
2. The non-transitory computer-readable medium of claim 1 , further comprising allowing only emergency communication and providing a visual indication indicating that only emergency communication is allowed when the monitored operating temperature is greater than the first threshold temperature and less than a second threshold temperature.
3. The non-transitory computer-readable medium of claim 2 , wherein the monitored operating temperature is a first monitored operating temperature, further comprising:
monitoring a second temperature at the device; and
inhibiting all communication when the second monitored operating temperature is greater than the second threshold temperature.
4. The non-transitory computer-readable medium of claim 1 , wherein the visual indication comprises an “EMERGENCY ONLY” indication.
5. A non-transitory computer-readable medium having computer-readable instructions stored on the non-transitory computer-readable medium for execution of the computer-readable instructions by a processor to use in a mobile device, said computer-readable instructions comprising:
monitoring an operating temperature at the device;
allowing only emergency communication when the monitored operating temperature is greater than a first threshold temperature and less than a second threshold temperature; and
inhibiting all communication when the monitored operating temperature is greater than the second threshold temperature.
6. The non-transitory computer-readable medium of claim 5 , further comprising allowing user-initiated communication requests for emergency and non-emergency communications from the mobile device when the monitored operating temperature is below the first threshold temperature.
7. The non-transitory computer-readable medium of claim 5 , further comprising:
receiving a user-initiated communication request while only emergency communication is allowed; and
allowing the emergency communication.
8. The non-transitory computer-readable medium of claim 5 , wherein the emergency communication comprises an emergency telephone call.
9. The non-transitory computer-readable medium of claim 5 , wherein the emergency communication comprises an emergency data message.
10. The non-transitory computer-readable medium of claim 5 , wherein the emergency communication comprises at least one of a communication with a public safety access point and a communication initiated by entry of an emergency telephone number.
11. The non-transitory computer-readable medium of claim 5 , wherein the monitored operating temperature comprises a monitored temperature of a battery of the mobile device.
12. A non-transitory computer-readable medium having computer-readable instructions stored on the non-transitory computer-readable medium for execution of the computer-readable instructions by a processor to use in a mobile device configured to communicate in a wireless network, said computer-readable instructions comprising:
detecting whether a temperature condition exists at the mobile device; and
when the temperature condition exists:
causing a visual indication to be presented, the visual indication indicating that the mobile device is in an emergency communication state;
operating to prohibit user-initiated communication requests for non-emergency telephone calls via the wireless network; and
operating to allow a user-initiated communication request for an emergency telephone call via the wireless network.
13. The non-transitory computer-readable medium of claim 12 , wherein when the temperature condition fails to exist:
operating to allow user-initiated communication requests for emergency and non-emergency telephone calls via the wireless network.
14. The non-transitory computer-readable medium of claim 13 , wherein the visual indication indicates “EMERGENCY ONLY”.
15. The non-transitory computer-readable medium of claim 12 , wherein detecting that the temperature condition exists further comprises:
monitoring a temperature based on signals read from a temperature sensor; and
detecting that the temperature condition exists based on the monitored temperature.
16. The non-transitory computer-readable medium of claim 12 , wherein detecting that the temperature condition exists further comprises:
monitoring a temperature from signals read from a temperature sensor; and
detecting that the temperature condition exists if the monitored temperature is greater than a predetermined threshold.
17. The non-transitory computer-readable medium of claim 16 , wherein the temperature sensor is in a battery or battery pack of the mobile device.
18. The non-transitory computer-readable medium of claim 12 , wherein the act of detecting that the temperature condition exists comprises detecting a temperature condition at which a battery of the mobile device may become damaged or explode.
19. The non-transitory computer-readable medium of claim 12 , wherein detecting whether the temperature condition exists comprises detecting whether a temperature condition of a power amplifier of the mobile device exists.
20. The non-transitory computer-readable medium of claim 12 , wherein the mobile device comprises a cellular telephone configured for communications in a cellular telephone network.
