Abstract

A service node is used in an intelligent communications network to provide services for customers. The node includes a service defining sub-system arranged to define a plurality of services. A first resource has a memory for storing speech segments, each segment having a corresponding identity, and a resource controller is arranged to convert a received command signal to a corresponding succession of speech segment identities for a speech announcement corresponding to the command signal. The first resource accesses the memory storing speech segments in accordance with the speech segment identities, to generate the corresponding speech segments for the speech announcement and provides an "announcement finished" signal when a last speech segment of the announcement has been generated. A switch is arranged to connect the first resource to an incoming call routed by the network to the service node. A node control is arranged to respond to an incoming call (i) to pass details of the call to the service defining sub-system for processing and queuing the call for subsequent processing if required due to already ongoing call processing, (ii) to logically connect the service defining sub-system to the first resource and to the switch, and (iii) to pass "announcement finished" signals from the first resource to the service defining sub-system.

Claims

1. A service node for use in an intelligent communications network for providing services for customers, said service node comprising:

service defining means arranged to define a plurality of services;

a first resource comprising means for recognizing customer-provided data and for storing said recognized data, a store for storing speech segments, each segment having a corresponding identity, and resource controlling means arranged (i) to convert a received command signal to a corresponding succession of speech segment identities for a speech announcement corresponding to the command signal, (ii) to access the speech segment store in accordance with said speech segment identities, (iii) to generate the corresponding speech segments for the speech announcement and (iv) to provide an announcement finished signal when a last speech segment of the announcement has been generated;

a switch arranged to connect the first resource to an incoming call routed by the network to the service node; and

node controlling means arranged to respond to said incoming call (i) to pass details of the call to the service defining means for processing and queuing the call for subsequent processing if required due to already ongoing call processing, (ii) to logically connect the service defining means to the first resource and to the switch, and (iii) to pass announcement finished signals from the first resource to the service defining means.

2. A service node as in claim 1, further comprising a second resource comprising means for recognizing customer-provided data and for storing said recognized data, and wherein the first resource is arranged to command a connection between the second resource and the incoming call and to command the second resource to activate the second recognizing and storing means and to provide said stored data therefrom to the first resource.

3. A service node as in claim 1, further comprising a second resource comprising means for recognizing customer-provided data and for storing said recognized data, and wherein the first resource is arranged to make a connection via itself between the second resource and the incoming call and to command the second resource to activate the second resource recognizing and storing means and to provide said stored data therefrom to the first resource.

4. A service node as in claim 1, wherein the first resource further comprises a database of customer-related data and means arranged to validate recognized customer-provided data by comparison with corresponding data stored in said database of customer-related data for the customer.

5. A service node as in claim 1, further comprising a third resource having a database of customer-related data and means arranged to validate recognized customer-provided data by comparison with corresponding data stored in said database of customer-related data for the customer and wherein the first resource is arranged to provide recognized data to the third resource and to command it to validate the provided data and provide to the first resource a signal indicative of the validation.

6. A service node as in claim 1, wherein the first resource is arranged to generate an announcement offering the customer a first plurality of numbered service-related options and to generate a further announcement offering a second plurality of numbered service-related options upon receipt of a recognized number from the customer.

7. A method of operating a service node in an intelligent communications network for providing services for customers, said method comprising the steps of:

receiving an incoming call routed by the network to the service node and passing details of the incoming call to a service defining means for processing and queuing the call for subsequent processing if required due to already ongoing call processing;

connecting a speech announcement resource to the incoming call in response to a request from the service defining means;

sending a command signal from the service defining means to the resource;

converting the command signal received by the resource to a corresponding succession of speech segment identities;

accessing a memory storing speech segments in accordance with said speech segment identities;

generating the corresponding speech segments;

providing an announcement finished signal when a last speech segment of the announcement has been generated;

receiving, at the resource, customer-provided data;

recognizing said received customer-provided data; and

storing said recognized data.

8. A method as in claim 7, wherein the recognizing and storing steps are performed by the speech announcement resource.

9. A method as in claim 7, further comprising the step of generating an announcement offering the customer a first plurality of numbered service-related options and generating a further announcement offering a second plurality of numbered service-related options upon receipt of a recognized number from the customer.

10. A method as in claim 7, further comprising the step of validating said recognized customer-provided data.

11. A method as in claim 10, wherein the validating step is performed by the speech announcement resource.
