Abstract

An improvement in the transparency of personal telecommunications over the prior art is achieved by automatically placing a return call from a personal communications unit of a called individual in response to a call from a caller and alerting the called individual to the existence of the call placed to his personal number only upon an indication that the call from the calling telephone remains in progress. In one embodiment of the invention, the called individual associates his personal communications unit with a telephone channel, before his reception of any calls. Should a caller make a call to the called individual'"'"'s personal calling number, the telephone network causes the transmission of an actuation signal. In response to the actuation signal, the personal communications unit places a call to a predetermined number over a switched telephone network using the aforementioned associated telephone channel. As long as the telephone network determines that the caller'"'"'s telephone call continues to be in progress, it sends an "in progress" signal over the telephone channel to the personal communications unit. During continued reception of the in-progress signal, the personal communications unit causes the generation of an alerting indication. A going off-hook on the telephone channel by a telephone during alerting results in completion of the caller'"'"'s telephone call to the seizing telephone. To this end, the telephone network stops sending the in progress signal and bridges the caller'"'"'s call to the return call placed by the personal communications unit.

Claims

1. A method for use in completing a telephone call that is initiated from a calling telephone to a called individual comprising the steps of:

receiving a call placed to a telephone number of said called individual from said calling telephone;

sending a signal for actuating a personal communications unit of said called individual without alerting the called individual;

receiving a call to a predetermined number placed automatically by said personal communications unit in response to said signal for actuating;

checking if said telephone call from said calling telephone continues to be in progress;

transmitting a signal indicating the said telephone call from said calling telephone continues to be in progress if the result of said step of checking is affirmative; and

then alerting the called individual for the first time, that the called individual is being called, so long as said telephone call from said calling telephone continues to be in progress.

2. The invention as defined in claim 1 including the further step of connecting said call from said calling telephone with said call placed by said personal communications unit.

3. The invention as defined in claim 2 including the further step of supplying answer supervision for said calling telephone substantially concurrently with said connecting step.

4. The invention as defined in claim 1 including the further steps of receiving a code that identifies said personal communications unit and said code determining whether said telephone call from said calling telephone is to be connected to said call placed automatically by said personal communications unit, and connecting the call from the calling telephone to the call placed by the personal communications unit when said telephone call from the calling telephone is to be connected to said call placed automatically by the personal communication unit.

5. The invention as defined in claim 1 including the step of supplying ringback signal to said calling telephone upon receipt of said call placed by said personal communications unit.

6. The invention as defined in claim 1 wherein said signal for actuating is a paging signal.

7. The invention as defined in claim 1 including the further step of sending over said call from said personal communications unit the telephone number of said calling telephone.

8. The invention as defined in claim 1 including the further steps of:

holding said call from said calling telephone for a predetermined period of time after said call from said personal communications unit has been disconnected; and

repeating said steps of receiving from said personal communications unit, checking and sending.
