Ensuring emergency availability of communications devices

   
   

A communications apparatus includes an energy storage device, such as a backup battery, that provides power in certain circumstances, such as when an external power supply is not available. The communications device determines an emergency threshold that provides sufficient power to communicate emergency information. The communications device also monitors the energy level remaining in the energy storage device and provides communications services so long as the energy level remaining in the energy storage device exceeds the emergency threshold.

Un appareillage de communications inclut un dispositif de stockage d'énergie, tel qu'une batterie de secours, qui fournit la puissance dans certaines circonstances, comme quand une alimentation d'énergie externe n'est pas disponible. Le dispositif de communications détermine un seuil de secours qui fournit la puissance suffisante de communiquer l'information de secours. Le dispositif de communications également surveille la force restante dans le dispositif de stockage d'énergie et fournit des services de communications à condition que la force restante dans le dispositif de stockage d'énergie excède le seuil de secours.
