Detecting 911 service disruptions
View Patent ↗Service disruptions in a 911 system are detected by receiving reports from mobile positioning centers that detail certain activities of the 911 system. These reports are compiled into a log. Parts of this log are then searched for conditions that would indicate a service disruption. For example, a certain number of errors appearing in the log in the last six hours may indicate a service disruption. If a condition that would indicate a service disruption is found, a notice is generated so that action may be taken.
1. A method of detecting 911 service disruptions, the method comprising:
receiving a request report from a mobile positioning center, wherein the request report comprises a plurality of requests made to the mobile positioning center;
processing the request report to generate a request log comprising the plurality of requests made to the mobile positioning center;
generating a group of entries of the request log associated with a public service answering point;
searching the group of entries of the request log for a search criteria that was satisfied over a limited time window; and
generating a notice if said search criteria is satisfied over said limited time window.
2. The method of claim 1 , wherein said searching comprises counting a number of failure indications reported by said mobile positioning center.
3. The method of claim 1 , wherein said limited time window is configurable.
4. The method of claim 1 , wherein said searching comprises counting a number of indications reported by said mobile positioning center that correspond to the public service answering point.
5. The method of claim 1 , wherein said search criteria comprises a ratio of a first type of indication to a second type of indication.
6. The method of claim 1 , wherein said search criteria comprises a cross-check of redundant data.
7. The method of claim 1 , wherein a number of indications reported by said mobile positioning center that correspond to the public service answering point are counted and said search criteria is satisfied by comparing said number of indications to a threshold value.
8. A communication network that detects 911 service disruptions, comprising:
a mobile positioning center that generates a request report, wherein the request report comprises a plurality of requests made to the mobile positioning center;
a location provisioning system that receives said request report, processes the request report to generate a request log comprising the plurality of requests made to the mobile positioning center, and generates a group of entries of the request log associated with a public service answering point; and
a monitor system configured to receive said request log and search the group of entries of the request log to determine if a search criteria was satisfied over a limited time window, said monitor system also generating a notice if said search criteria was satisfied over said limited time window.
9. The communication network of claim 8 , wherein the monitor system configured to search the group of entries of the request log comprises the monitor system configured to count a number of failure indications indicated by said request log.
10. The communication network of claim 8 , wherein said limited time window is configurable.
11. The communication network of claim 8 , wherein the monitor system configured to search the group of entries of the request log comprises the monitor system configured to count a number of indications indicated by said request log that correspond to the public service answering point.
12. The communication network of claim 8 , wherein said search criteria comprises a ratio of a first indicator to a second indicator.
13. The communication network of claim 8 , wherein said search criteria comprises a cross-check of redundant data.
14. The communication network of claim 8 , wherein a number of indications in said request report are correlated to the public service answering point and counted to produce a count and said count is compared to a threshold value.
15. A program storage device to detect 911 service disruptions, the program storage device comprising:
software instructions configured, when executed by a computer system, to direct the computer system to receive a request report from a mobile positioning center, wherein the request report comprises a plurality of requests made to the mobile positioning center, process the request report to generate a request log comprising the plurality of requests made to the mobile positioning center, generate a group of entries of the request log associated with a public service answering point, search the group of entries of the request log for a search criteria that was satisfied over a limited time window, and generate a notice if the search criteria is satisfied over the limited time window; and
at least one non-transitory computer-readable storage medium storing the software instructions.
16. The program storage device of claim 15 , wherein the software instructions configured to direct the computer system to search the group of entries of the request log for the search criteria comprises the software instructions configured to direct the computer system to count a number of failure indications reported by said mobile positioning center.
17. The program storage device of claim 15 , wherein said limited time window is configurable.
18. The program storage device of claim 15 , wherein the software instructions configured to direct the computer system to search the group of entries of the request log for the search criteria comprises the software instructions configured to direct the computer system to count a number of indications reported by said mobile positioning center that correspond to the public service answering point.
19. The program storage device of claim 15 , wherein said search criteria comprises a ratio of a first type of indication to a second type of indication.
20. The program storage device of claim 15 , wherein a number of indications reported by said mobile positioning center that correspond to the public service answering point are counted and said search criteria is satisfied by comparing said number of indications to a threshold value.
