Title: METHOD AND APPARATUS FOR SELECTIVE CALL FORWARDING
Abstract:
The present invention provides a selective automatic call forwarding method and system. In response to a request from a subscriber for the selective call forwarding service, a selective call forwarding service record is created for the subscriber which includes the subscriber's telephone number, a 'trigger' telephone number, and a call forwarding number associated with the trigger number. An example of the trigger number might be the subscriber's Internet access telephone number. An example of the call forwarding number might be the subscriber's mobile telephone number. A determination is made, e.g. a flag is set in the subscriber record, whenever the subscriber is engaged in a communication initiated to the trigger number. Thereafter, incoming calls directed to the subscriber are automatically forwarded to the call forwarding number. However, if the subscriber is currently engaged in a communication with a telephone number other than the trigger number registered in the subscriber's call forwarding service record, incoming calls are handled in a manner other than forwarding the incoming call to the call forwarding number. Such other procedures might include, for example, generation of a busy signal, execution of a call waiting service, or execution of a call completion service.
