System and method for routing a special number call from a calling unit to an answering point

摘要

A system for routing a special number call from a calling unit to an answering point based upon location of the calling unit includes: (a) a communication network configured for effecting communicative coupling between the calling unit and one or more receiving answering point; each receiving answering point having a respective responsibility area; (b) a mobile positioning center coupled with the communication network; the mobile positioning center determining the location of the calling unit within a first location area; (c) a communication switch coupled with the communication network and coupled with the answering point; and (d) a controller unit coupled with the communication switch for controlling selected operations of the communication switch. The mobile positioning center and the controller unit cooperate to effect routing a call from the calling unit to each respective answering point having a respective responsibility area at least partly common with the first location area.

1. A system for concurrently routing a special number call from a calling unit to at least two receiving answering points having geographic responsibility area at least partly in common with a first geographic location area of said calling unit, without regard to caller ID of said calling unit; the system comprising:
(a) at least one communication network; each respective communication network of said at least one communication network being configured for effecting communicative coupling between said calling unit and said receiving answering points; each of said receiving answering points having a respective geographic responsibility area; (b) at least one mobile positioning center coupled with said at least one communication network; said at least one mobile positioning center determining said geographic location of said calling unit within a first geographic location area; (c) at least one communication switch coupled with said at least one communication network and coupled with said receiving answering points; and (d) at least one controller unit coupled with said at least one communication switch for controlling selected operations of said at least one communication switch;wherein said at least one mobile positioning center and said at least one controller unit cooperating to effect concurrently routing a call from said calling unit to each said receiving answering point having a respective geographic responsibility area at least partly common with said first geographic location area; andwherein routing to at least one of said at least two receiving answering points is torn down upon determining with greater accuracy a second geographic location area of said calling unit.
