Abstract

In a telephone network, a platform is coupled to a profile database and a telecommunications relay center. A voice telephone or text telephone caller dials a telephone number for a text telephone subscriber. The platform receives the telephone call and generates voice and text prompts for the caller. The platform senses calling equipment type by listening for the caller'"'"'s response to the prompts. The platform accesses the profile database and retrieves a prioritized sequence of one or more telephone numbers corresponding to activated locations for the text telephone subscriber. If the caller is a text telephone user, the text telephone call is routed by the platform directly to the text telephone subscriber. If the caller is a voice telephone user, the voice telephone call is relayed through the relay center to the text telephone subscriber.

Claims

1. A telecommunications system for use in a telephone network to process communications with a telecommunications relay center, comprising:

a platform for routing a telephone call based on an equipment type for the telephone call; and

a profile database for supplying a particular data record which includes at least one potential destination for a text telephone party and information identifying the relay center. wherein

the platform includes signal detection circuitry for determining that the call is a voice call,

the platform routes the voice call to the relay center, and

said at least one potential destination is identified to the relay center in association with said voice call.

2. The invention as defined in claim 1, wherein:

the relay center is operative to automatically complete the voice call as a telecommunications relay session to the text telephone party.

3. The invention as defined in claim 1, wherein:

the relay center is operative to complete the voice call as a telecommunications relay session to the text telephone party upon actuation by a communications assistant.

5. The invention as defined in claim 1, wherein:

the profile database includes a plurality of data records, and each of the plurality of data records includes a sequence of numbers for routing the telephone call to the text telephone party and a number for the relay center.

4. A telecommunications system for use in a telephone network to process communications with a telecommunications relay center, comprising:

a platform for routing a telephone call based on an equipment type for the telephone call; and

a profile database for supplying a particular data record which includes at least one potential destination for a text telephone party and information identifying the relay center, wherein;

the platform includes signal detection circuitry for determining that the call is a text call; and

the platform operates

(i) to access a data record which includes at least one potential destination for the text telephone party, and

(ii) to route the text call to said potential destination.

6. A method of routing a telephone call for use in a telephone network which includes a telecommunications relay center, comprising the steps of:

(A) retrieving a prioritized list of potential destinations for a text telephone party in response to the telephone call; and

(B) routing the telephone call using the prioritized list, wherein the telephone call can be routed directly to a potential destination for the text telephone party or to said relay center as a function of the type of telephone station originating said telephone call; and

further comprising the step of

generating a prompt responsive to the telephone call to determine the type of telephone station originating the telephone call.

7. The invention as defined in claim 6, further comprising the steps of:

detecting a voice response to the prompt; and

identifying that the telephone call originated from a telephone station configured as a voice telephone station.

8. The invention as defined in claim 6, further comprising the steps of:

detecting a text response to the prompt; and

identifying that the telephone call originated from a telephone station configured as a text telephone station.

9. The invention as defined in claim 6, further comprising the steps:

accessing a profile database in response to the telephone call; and

retrieving one or more identifiers for use in routing the telephone call.

10. The invention as defined in claim 9, wherein:

the one or more identifiers include a telephone number.

11. The invention as defined in claim 6, further comprising the steps of:

accessing a profile database to retrieve a telephone number for the text telephone party and a number for the relay center;

transferring the telephone call to the relay center; and

passing the telephone number to the relay center.

12. A telecommunications system for use in a telephone network to process communications with a telecommunications relay center, comprising:

means for detecting an equipment type used for making a telephone call;

a database; and

means for (i) retrieving a data record for routing the telephone call, and (ii) routing the telephone call to a text telephone party based on the equipment type and a record retrieved from the database;

wherein

the means for detecting includes signal detection circuitry for determining that the telephone call is a voice call.

13. The invention as defined in claim 12, wherein:

the data record includes a number corresponding to a potential destination for the text telephone party.

14. The invention as defined in claim 12, wherein:

the data record includes a sequence of numbers and a number corresponding to the relay center.

15. The invention as defined in claim 12, wherein:

the data record includes at least one potential destination for the text telephone party and a number corresponding to the relay center.
