System and method for recognizing and routing telephone calls involving hearing or speech impaired persons
First Claim
1. A system for recognizing and routing telephone call activity involving a hearing or speech impaired person, comprising:
- a switching network having one or more switches for mounting telephone call activity, said telephone call activity having been initiated by a caller dialing a three digit prefix together with a called party number;
wherein said three digit prefix indicates that one of the parties involved in said telephone call activity is hearing or speech impaired;
the switching network coupled to an originating telephone call location and a destination telephone call location;
a first database means coupled to the switching network for analyzing origination and destination information associated with the telephone call activity so as to retrieve a profile of the hearing or speech impaired person involved in said telephone call activity;
a signaling network coupling the switching network with the first database means for transmitting the origination and destination information from said switching network to said first database means, and for transmitting said profile from said database means to said switching network;
an adjunct coupled to the switching network for controlling routing of the telephone call activity in the system;
a first interface for routing the telephone call activity, including said profile, from the switching network to the adjunct in response to the dialing of said three digit prefix by said caller; and
a relay center operably connected to the adjunct for servicing said telephone call activity when a hearing or speech impaired person is involved.

Abstract
A system and method are disclosed for recognizing and routing telephone call activity involving a hearing or speech impaired person. A caller places a local, intra-LATA, or inter-LATA telephone call by adding a three digit prefix to a called party number (CPN); the prefix identifies the call as one in need of routing to an Operator Services for the Deaf (OSD) or Tele-communications Relay Services (TRS) center. The call is first routed to a switching network where a query is sent to a Universal Subscriber Data Structure database using the caller'"'"'s Automatic Number Identification (ANI) and the CPN of the called party. The database responds with the caller'"'"'s and the called party'"'"'s profiles. Thereafter, the call is routed to an adjunct which connects the call to an appropriate OSD or TRS center, whereupon the conversation can be relayed between the hearing or speech impaired person and the voice party. During this time, the adjunct can monitor a call for a particular subscriber'"'"'s feature interaction, and can route the call to an appropriate switch in the network based upon the feature invoked by that party. A second and third database connected to the adjunct can verify feature subscriptions and perform calling card validation, respectively.

10. A system for recognizing and routing telephone call activity involving a hearing or speech impaired person, comprising:
-
a switching network having one or more switches for routing telephone call activity, said telephone call activity having been initiated by a caller using "operator cut-through"; wherein said "operator cut-through" comprises a yoice caller dialing "00" and verbally indicating that one of the parties involved in said telephone call activity is hearing or speech impaired, and a hearing or speech impaired caller dialing a called party number plus a suffix to indicate same; the switching network coupled to an originating telephone call location and a destination telephone call location; database means coupled to the switching network for analyzing origination and destination information associated with the telephone call activity so as to retrieve profiles of the caller and called party; a signaling network coupling the switching network with the database means for transmitting the origination and the destination information from said switching network to said database means, and for transmitting said profiles from said database means to said switching network; an adjunct coupled to the switching network for controlling routing of the telephone call activity in the system; a first interface for routing the telephone call activity, including said profiles, from the switching network to the adjunct in response to the use of "Operator Cut-Through" by said caller; and a relay center operabl y connected to the adjunct for servicing the telephone call activity when a hearing or speech impaired person is involved. - View Dependent Claims (11, 12, 13, 14, 15, 16, 25)

17. A method for recognizing and routing a telephone call involving a hearing or speech impaired person, comprising the steps of:
-
routing a telephone call from an originating telephone call location over a switching network to a destination telephone call location, said telephone call having been initiated by a caller dialing a three digit prefix along with a called party number; said three digit prefix indicating that one of the parties involved in said telephone call is hearing or speech impaired; transmitting origination and destination information from said switching network to a first database means via a signaling network; said first database means analyzing the origination and the destination information associated with the telephone call and retrieving a profile of the hearing or speech impaired person involved in said telephone call; transmitting said profile from said first database means to said switching network via said signaling network; routing the telephone call from the switching network to an adjunct via a first interface in response to the dialing of said three digit prefix by said caller; and the adjunct routing the telephone call to a center which relays conversations between hearing or speech impaired persons and persons whose hearing or speech is not impaired. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

26. A method for recognizing and routing a telephone call involving a hearing or speech impaired person, comprising the steps of:
-
routing a telephone call initiated by a caller using "operator cut-through" from an originating telephone call location over a switching network to a destination telephone call location; wherein said "operator cut-through" comprises a voice caller dialing "00" and verbally identifying the telephone call as one involving a hearing or speech impaired person, and a hearing or speech impaired caller dialing a called party number plus a suffix to identify same; transmitting origination and destination information from said switching network to a database means; the database means analyzing the origination and the destination information associated with the telephone call and retrieving profiles of the caller and called party; transmitting said profiles from said database means to said switching network; routing the telephone call from the switching network to an adjunct via a first interface in response to said profiles indicating that one of the parties involved in said telephone call is hearing or speech impaired; and the adjunct routing the telephone call to a center which relays conversations between hearing or speech impaired persons and persons whose hearing or speech is not impaired. - View Dependent Claims (27, 28, 29, 30, 31, 32)
