Abstract

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.

Claims

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; and

wherein 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.

2. A method 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 method comprising;

(a) in no particular order;

(1) providing 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;

(2) providing 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;

(3) providing at least one communication switch coupled with said at least one communication network and coupled with said at least two answering points; and

(4) providing at least one controller unit coupled with said at least one communication switch for controlling selected operations of said at least one communication switch; and

(b) operating said at least one mobile positioning center and said at least one controller unit cooperatively 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; and

(c) operating said at least one mobile positioning center and said at least one controller to effect tearing down routing to at least one of said at least two receiving answering points upon determining with greater accuracy a second geographic location area of said calling unit.
