Abstract

A method for handling alarm conditions from paging stations in a paging system is disclosed. The paging system includes a paging terminal, a plurality of paging stations, and a network manager. When a paging station has an alarm condition, the paging station forwards the alarm to the network manager, which in turn, compares the alarm with an alarm record for that paging station and determines whether or not that alarm is a higher priority than the previous alarms received from the paging station. If so, the network manager transmits a signal to the paging terminal to page the technician responsible for servicing that particular paging station. The technician is paged and dispatched to the paging station for service.

Claims

1. A method of processing a current alarm in a paging system said paging system including a plurality of paging stations and a network manager said current alarm originating from a one of said paging stations to indicate an alarm condition at said one of said paging stations, the method including the steps of:

maintaining an alarm record said alarm record including a record of previous alarms received from each said one of said paging stations;

comparing said current alarm with a predetermined set of said previous alarms in said alarm record to determine if said current alarm is a duplicate of any of said predetermined set of said previous alarms;

alerting a technician of said current alarm if said current alarm is not a duplicate of any of said predetermined set of said previous alarms; and

determining whether an ALERT_-- ENABLE flag is high, and if so, even if said current alarm is a duplicate of any of said predetermined set of said previous alarms, alerting the technician.

2. The method of claim 1 further including the step of determining said set of predetermined previous alarms as those previous alarms within a predetermined filter time of said current alarm.

3. The method of claim 2 further including the step of determining said set of predetermined previous alarms as those previous alarms within a predetermined filter time of said current alarm and as those previous alarms that resulted in said technician being alerted.

4. The method of claim 1 further including the step of determining said set of predetermined previous alarms as those previous alarms that resulted in said technician being alerted.

5. The method of claim 1 wherein the step of alerting includes the step of sending a page to said technician through said paging system.

6. The method of claim 1 further including the step of adding said current alarm to said alarm record.

7. A method of processing a current alarm in a paging system, said paging system including a plurality of paging stations and a network manager, said current alarm originating from a one of said paging stations to indicate an alarm condition at said one of said paging stations, the method including the steps of:

maintaining an alarm record, said alarm record including a record of previous alarms received from each said one of said paging stations;

comparing said current alarm with a predetermined set of said previous alarms in said alarm record to determine if said current alarm is of higher priority than any of said predetermined set of said previous alarms;

alerting a technician of said current alarm only if said current alarm is of higher priority than any of said predetermined set of said previous alarms; and

determining whether an ALERT_-- ENABLE flag is high, and if so, even if said current alarm is of lower priority than any of said predetermined set of said previous alarms, alerting the technician.

8. The method of claim 7 further including the step of determining said set of predetermined previous alarms as those previous alarms within a predetermined filter time of said current alarm.

9. The method of claim 8 further including the step of determining said set of predetermined previous alarms as those previous alarms within a predetermined filter time of said current alarm and as those previous alarms that resulted in said technician being alerted.

10. The method of claim 7 further including the step of determining said set of predetermined previous alarms as those previous alarms that resulted in said technician being alerted.

11. The method of claim 7 wherein the step of alerting includes the step of sending a page to said technician through said paging system.

12. The method of claim 7 further including the step of adding said current alarm to said alarm record.
