Method and system for conserving power in a telecommunications network during emergency situations
| DWPI Title: Method for conserving power in wireless telecommunication network during e.g. natural disaster by cellular telephone, involves dropping call if digits do not match entries in permissible number list |
| Abstract: Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls. |
| Use: Method for conserving power in a wireless telecommunication network during an emergency situation e.g. natural disaster, terrorist attack and power outage, by a wireless communication device e.g. cellular telephone, personal digital assistant and laptop computer. |
| Advantage: The method enables conserving power for emergency calls and priority calls and back-up power sources to last longer in the emergency situation, thus reducing telecommunication network traffic that occurs during the emergency situation to ensure that enough bandwidth exists for emergency calls. The method enables a telecommunication network manager to send a signal to a base station from a remote location to alert the base station about the emergency situation, so that a device in the telecommunication network can automatically sense when power outage occurred to determine when the emergency situation existed and transmits the signal to another device in the network when the power outage occurs. The method enables maintaining permissible number lists in the telecommunication network, so that amount of power conservation can be varied by restricting the calls using different lists based on seriousness of the situation. |
| Novelty: The method involves identifying which type of a set of types of emergencies characterizes an emergency situation. A permissible number list is selected from a set of permissible number lists that is tied to identified type of the emergency situation. Digits are compared to a set of entries in the permissible number list. A call is routed (340) if the digits match one of the entries in the entries in the permissible number list. The call is dropped (350) if the digits do not match the entries in the permissible number list in response to determining that the emergency situation exists. |
