Abstract:
1. A method for automatically updating routing information for routing of special number calls comprising: receiving a plurality of routing parameters relating to a communications device from a plurality of sources; determining a differential related to the plurality of routing parameters; each respective routing parameter of said plurality of routing parameters being expressed in a respective record; said differential indicating one of a difference between a first predetermined characteristic of a first record expressing a first said respective routing parameter and said first predetermined characteristic of a second record expressing a second said respective routing parameter and a difference between a second predetermined characteristic of a selected record expressing a selected said respective routing parameter and a predetermined threshold established with respect to said plurality of routing parameters; comparing the determined differential to other previously determined differentials related to previously received routing parameters associated with the communications device; selecting one of the routing parameters relating to a communications device based on said comparison; and providing the selected routing parameter for routing of special number calls received from the communications device; said differential comprising one of a difference between time stamps associated with said first record and said second record and a difference between time stamps associated with said selected record and said threshold.
