Apparatus, and associated method, for facilitating routing of a call to a public safety answering point
First Claim
1. In a telephonic communication system permitting of a call, originated at a calling station, to be placed to a selected public safety answering point of a set of public safety answering points by way of a call routing entity of a set of call routing entities, an improvement of apparatus for facilitating service handling of the call to the selected public safety answering point together with providing selected information pertaining to the calling station to the selected public safety answering point, said apparatus comprising:
- a centralized routing data base maintainable in communication connectivity with each call routing entity of the set of call routing entities, said centralized routing data base containing a listing indexing together a calling-station identity of the calling station and a public safety identity of at least one of the public safety access points, said centralized routing data base accessed by the call routing entity by way of which the call is placed at least to identify the selected public safety answering point to which to route the call, the selected public safety answering point comprising the public safety answering point indexed together with the calling station; and
a signaling transfer point (STP) having the centralized routing database at the STP, wherein the STP directly accesses the centralized routing data base, wherein the centralized routing data base is maintained in communication connectivity with each call routing entity by way of the STP, and wherein the information of the centralized routing data base is updated by way of the signaling transfer point.

Abstract
Apparatus, and an associated method, for facilitating service handling of a call placed to a public safety answering point using a universal dialing code, such as an emergency 9-1-1 dialing code. A centralized routing database is formed and maintained. When a call is originated and routed to a call routing entity, the centralized routing data base is accessed to obtain the identity of the public safety answering point to which to route the call. Thereby, a call connection is formed to an appropriate public safety answering point. Due to the centralized nature of the routing data base, updates to the data base are readily and easily ascertainable.

10. In a method for communicating in a telephonic communication system permitting of a call, originated at a calling station, to be placed to a selected public safety answering point of a set of public safety answering points by way of a call routing entity of a set of call routing entities, an improvement of a method for facilitating service handling of the call to the selected public safety answering point together with providing selected information pertaining to the calling station to the selected public safety answering point, said method comprising:
-
forming a centralized routing data base at a signaling transfer point (STP) containing a listing indexing together a calling station identity of the calling station and a public safety identity of at least one of the public safety answering points, the centralized routing data base maintainable in communication connectivity with each call routing entity of the set of call routing entities by way of the STP; routing the call, when originated at the calling station, to the call routing entity of the set of call routing entities; accessing the STP, from the call routing entity, and directly accessing by the STP the centralized routing data base, to identify therefrom the selected public safety answering point to which further to route the call, the selected public safety answering point comprising the public safety answering point indexed together with the calling station; and updating the information of the centralized routing data base by way of the signaling transfer point. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
