Abstract

A method for providing telecommunication service to a terminal includes loading a text-based script. The text-based script includes a service definition identifying a user interface web service and an address for the user interface web service. The text-based script also includes a signaling web service definition identifying a signaling web service and an address for the signaling web service. Additionally, the text-based script includes a user interface event handler identifying a user interface event type and including a call to the user interface web service, and a signaling event handler identifying a signaling event type and including a call to the signaling web service. The method additionally includes registering with the user interface web service by communicating a text-based message to the address of the user interface web service, and registering with the signaling web service by communicating a text-based message to the address of the signaling web service. The method further includes receiving an incoming event, determining that the incoming event corresponds to the user interface event type or the signaling event type, and communicating a service request to the address of one of the user interface web service or the signaling web service.

register with the user interface web service;

receive a text-based incoming event from the signaling web service indicating an incoming call;

determine that the incoming event corresponds to the user interface event type;

communicate a service request to the user interface web service;

send a ring service request to the user interface web service in response to receiving the text-based incoming event from the signaling web service;

wait a predetermined period of time after sending the ring service request;

send a service request to a voicemail web service, after the predetermined period of time; and

send a stop ringing service request to the user interface web service after sending the service request to the voicemail web service; and

a user interface web service, operable to provide low level interface to audio output, audio input, user input, and display, and operable to engage in text-based messaging with controlling process.

8. The system of claim 7, wherein the service request comprises Extensible Markup Language (XML) instructions.

9. The system of claim 7, wherein the controlling process is further operable to communicate the service request by using the HyperText Transfer Protocol (HTTP).

10. The system of claim 7, wherein the controlling process is further operable to receive a service response from the web service.

11. A system for providing modular telecommunication service comprising:
